▼ This thesis investigates variability in airway caliber and the distribution of ventilation within the human lung as thought to occur in asthma. Currently, the understanding of how an integrated network of airways can lead to temporal and spatial variation as found in the human lung is unclear. Throughout this thesis, a multibranch airway tree model was used in a forward modeling approach. In a variability study, the mean airway resistance (RL) was observed to be proportional to the standard deviation in airway resistance (SDRL) as reported in the literature under several conditions of airway diameter indicating the strong robustness of this behavior. The model predicted previously reported RL distributions and the reported proportionality of SDRL and RL, but only when we included coherency between airways. In a second study, patient specific ventilation was investigated using an image functional approach by closing specific airways (creating defects) identified by hyperpolarized 3He MRI from asthmatic subjects. Impedance predictions from the imposed heterogeneous ventilation were then calculated and correlated to 3He MRI ventilation defect percent (VDP), plethysmography, and spirometry data. These predictions suggest the forced oscillation technique (FOT) to be a superior metric toward the evaluation of the VDP. In a third study, we investigated how asymmetric branching could play a role in ventilation defect emergence and persistence. At high muscle activation levels simulating an asthmatic episode, airway trees with greater asymmetry reached steady state sooner, with defects that were more persistent in location, had lower RL values (~50%), and greater EL values (~25%) after bronchoconstriction. These results suggest the initial formation of ventilation defects was dependent on airway instability; however, the location and persistence of ventilation defects may be due to geometric airway structure. By modeling the contribution of ventilation defects to lung impedance, we were able to show that defects can play a role in governing the relationship between RL and its variation, and the effect of defects through VDP could be better assessed using FOT. Moreover, lung structure contributed to the emergence and persistence of ventilation defects, meaning that defects could be potentially ameliorated through structural intervention.

Additional Thesis work performed as part of the master Hydraulic Engineering at Delft University of Technology in collaboration with University of Southampton, Ocean and Earth Sciences, Physical Oceanography - In this research the outcome of several realisations of 10 different models from the CMIP5 program is used to predict the El Niño/Southern Oscillation (ENSO).With her extreme phases ’El Niño’ and ’La Niña’, ENSO is probably the most infamous oceanographic and climate phenomenon in the physical climate system with a great influence on the world’s climate and weather systems. Despite the fame amongst public and the high importance in research programmes throughout the last decades, the potential causes, cyclicity patterns and the possible forcing of ENSO are still not fully understood. Even with state of the art models its predictability (up to 12 months ahead) remains quite low compared to the time scale of the phenomenon (2-5 years). In this study a statistical model is developed to predict ENSO with a transfer operator framework based on model output from 10 models. This method is based on a recent study by Sévellec [19] and transforms a deterministic single time series evolution of sea surface temperature in the Tropical Pacific, extracted from existing coupled atmosphere-ocean model data, into a probabilistic method to determine the evolution of an observational initial condition in time. The main goal of this research is to explore and define by means of hindcasting (predicting the past) the predictive skills and reliability of this statistical method. The results show that the reliability is similar to previous studies. Where the most computational extensive coupled ocean-atmosphere models show a good prediction skill up to 9 months, with this quick model a similar skill is sustained up to a prediction window of 5 months. Since this is the first time this method applied on ENSO, recommendations are done for further development of the model as well as for the application on ENSO. Suggestions for potential other systems this model could be applied to are made.

▼ Considerable efforts have been made in recent decades to diagnose how the climate of our planet is changing in response to anthropogenic greenhouse gas forcing. There are considerable risks associated with a warming climate, with possible hazards to life, property, economy, and the environment. These changes and the risks associated with them are inherently uncertain, and scientists use tools such as global coupled climate model ensembles to attempt to quantify these uncertainties. Quantifying different types of uncertainties involved in modeling the Earth’s climate system is of high importance as processes within the climate system are chaotic and challenging to predict. This dissertation contains a comprehensive quantification of climate uncertainty, focusing primarily on the uncertainty due to coupled atmosphere-ocean internal variability, utilizing a global coupled climate model ensemble (the Community Earth System Model; CESM). Here, this work poses key science questions related to quantifying internal variability in three different model variables, all of which are important in the context of a changing climate. Firstly, uncertainties surrounding decadal trends in depth-integrated, drift-removed global steric sea-level rise are evaluated. Results show that the effects of both internal variability and structural model differences contribute substantially to uncertainties in modeled steric sea-level trends for recent decades and the magnitude of these effects vary with depth. Uncertainties are amplified for regional assessments, highlighting the importance of both sources of variability when considering uncertainties surrounding modeled sea-level trends. Results can provide useful constraints on estimations of global and regional sea-level variability, in particular for areas with few observations such as the deep ocean and the Southern Hemisphere. Secondly, a statistical framework using a block-maxima approach is used to analyze the representation of warm temperature extremes in global climate model ensembles. Uncertainties due to structural model differences, grid resolution and internal variability are characterized and discussed. Results show that models and ensembles differ greatly in the representation of extreme temperature over the United States, but that there is overwhelming evidence suggesting variability in tail events is dependent on time and anthropogenic warming. These sources of variability can considerably influence the uncertainty of modeled extremes. Several idealized regional applications are highlighted for evaluating ensemble skill, based on quantile analysis and root mean square errors in the overall sample and the upper tail. Results are relevant to regional climate assessments that use global model outputs and that are sensitive to extreme temperatures. Lastly, this dissertation evaluates internal variability in ocean adjustment in the low-resolution CESM ensembles, by assessing ocean temperature. Uncertainty due to internal variability is used as a proxy to quantify the timescales… Advisors/Committee Members: Sriver, Ryan (advisor), Sriver, Ryan (Committee Chair), Trapp, Robert (committee member), Wang, Zhuo (committee member), Dominguez, Francina (committee member).

▼ Glaciers change length in response to fluctuations in climate. In addition, atmospheric and geomorphic processes modulate glacier response to climate change. These factors must be explored in detail to understand glacier response. I engage two factors modulating glacier response: 1) the effect of year-to-year weather variability on glacier length and 2) the effect of debris cover on glacier dynamics. I use case studies from the Last Glacial Maximum (LGM) in Colorado in addition to modern glaciers in the Nepalese Himalaya and Alaska to address these issues. The effect of interannual variability on the moraine record Multi-decadal, kilometer-scale fluctuations in glacier length occur in response to stochastic, year-to-year variability in mass balance. I address the effect of weather variability on our interpretation of the moraine record using glacier models in the Colorado Front Range during the LGM. My analyses suggest that (1) glacial standstills longer than 50 years were unlikely; (2) mean glacier lengths are ~10%-15% up-valley from maximum glacier lengths; and (3) individual LGM terminal moraines were formed by a combination of a climate change and interannual variability-forced advances. Numerical modeling of debris-covered glaciers Debris cover can significantly affect the length and dynamics of valley glaciers. I developed a 2D vertical plane long-valley numerical glacier model with which we explore the feedbacks between debris and ice dynamics. Debris input to the glacier in the accumulation zone emerges in the ablation zone, and is then advected along the glacier surface, damping melt rate. Debris cover reduces ice surface slopes, ice thickness gradients, ice discharge gradients, and englacial velocities in the ablation zone. Ice cliffs on debris-covered glaciers Debris cover suppresses ice melt on glaciers. However, the retreat of debris-free ice cliffs within otherwise debris-covered glaciers counters the insulating effects of debris. I provide a theoretical framework for the production and removal of ice cliffs and glacier surface topography on the Kennicott Glacier, Wrangell Mountains, Alaska. Mean debris thickness exerts primary control on glacier surface relief and ice cliff concentration. Approximately 30% of net mass loss from the study area is due to the retreat of ice cliffs.

▼ The continued push for microelectronics scaling has driven many changes in modern transistor design, such as the adoption of non-planar, multi-gate architectures (e.g., FinFETs) starting at the 22nm node. It is envisioned that other solutions such as junctionless FETs (JL-FETs), tunnel FETs (TFETs), or heterogeneous materials integration may be needed to sustain the pace of Moore’s law beyond 14nm. To assess the viability of these emerging devices prior to commercial investment, we must consider the impact of process variations such as line edge roughness (LER) and random dopant fluctuation (RDF), both of which are major concerns in the nanoscale regime. The challenges associated with dimensional scaling also compel us to explore heterogeneous integration as a possible end-of-roadmap solution for future micro- and nanoelectronics.In this dissertation, we first present our findings on the impact of LER and RDF variability on FinFETs, JL-FETs, and TFETs targeted for sub-32nm generations. Using technology computer-aided design (TCAD) simulations combined with physical descriptions by which LER and RDF affect the intrinsic operation of different FETs, we compare the impact of LER and RDF on the emerging candidates of interest. We extend the study to include III-V FETs as well to determine if materials like InGaAs are inherently more or less affected by variability compared to equivalently designed silicon devices. Second, we study how heterogeneous integration (HGI) of different material systems can drive a new approach toward improving circuit and system performance outside of traditional scaling concepts. To this end, we develop a cross-layer evaluation framework (spanning process, device, and circuit-level perspectives) to assess the potential benefits of InGaAs/Ge-based HGI circuits against silicon-only technology. To give credence to the framework, we also present experimental work in developing a nanotransfer printing process to enable feature-level HGI in real-world settings. Third, we present a method to fabricate coplanar supercapacitors onto silicon substrates for integration with microelectronic circuits. Along with experimental demonstrations, we also develop a physical TCAD model to enable simulation-based design exploration and optimization of on-chip supercapacitors for integrated circuit applications.Ultimately, the insights gained in this study will help guide the semiconductor industry to choose next-generation device technologies which are best suited for commercial adoption with process variability and the potential for heterogeneous integration in mind.

Циљ докторске дисертације био је да се применом популационе фармакокинетичке анализе идентификују и квантификују фактори фармакокинетичке варијабилности такролимуса и сиролимуса у пацијената са трансплантираним бубрегом. Сви коришћени подаци, укључујући измерене концентрације лекова, били су део редовног терапијског и клиничког праћења пацијената. Популациона анализа вршена је коришћењем софтвера NONMEM®. Подаци за такролимус за период до 6 месеци и период од око годину дана након трансплантације анализирани су независно. Према критеријумима за укључивање/искључивање укупно је у групи за рани период након трансплантације било 105 пацијената, док је у групи за период од око годину дана након трансплантације било 45 пацијената. Развијени модели валидирани су техникама интерне валидације. Групу за развој модела за сиролимус чинили су подаци 25 пацијената, док су подаци 13 пацијената коришћени за екстерну валидацију. Додатно, развијени модел за сиролимус валидиран је и техникама интерне валидације. Као фактори фармакокинетичке варијабилности оралног клиренса (CL/F) такролимуса у првих 6 месеци након трансплантације идентификовани су протекло време од трансплантације, укупна телесна маса, хематокрит, ниво аспартат аминотрансферазе (АST) и укупни протеини плазме. На вредности CL/F у периоду од око годину дана након трансплантације значајно су утицали укупна телесна маса и дневна доза такролимуса. Део варијабилности у CL/F сиролимуса објашњен је старошћу и функцијом јетре, израженом преко АST. Валидација развијених модела показала је њихову стабилност и адекватну предиктабилност. Примена добијених валидираних модела омогућава израчунавање индивидуалних вредности CL/F, параметра који је основ за индивидуализацију режима дозирања.

▼ Global mean surface temperatures (GMST) warmed in the early 20th century, experienced a mid-century lull, and warmed again steadily until 1997. Observations at the turn of the 21st century have revealed another period of quiescent warming of GMSTs from 1998 to 2012, thus prompting the notion of a global warming “hiatus”. The warming hiatus occurred concurrently with steadily increasing atmospheric greenhouse gas concentrations, sea level rise, and retreating arctic sea ice. The occurrence of the warming hiatus suggests that natural variability continues to be a sizable contributor to modern climate change and implies that energy is rearranged or changed within the climate system. Much of the scientific research conducted over the last decade has attempted to identify which modes of natural variability may be contributing to the GMST signal in the presence of anthropogenic warming. Many of these studies concluded that natural variability, operating in the global oceans were the largest contributors to GMST. What remains unclear is how oceanic variability and its contribution to GMST may change on a warmer globe as greenhouse gas concentrations continue to rise. Our research includes diagnostic analyses of the available observational surface temperature estimates and novel state-of-the-art climate model experiments from the fifth phase of the Coupled Model Intercomparison Project (CMIP5). Our analyses seek to understand how the natural modes of variability within the ocean will change under different warming scenarios. Utilizing simulations forced with observed pre-industrial and historical greenhouse gas emissions in combination with several future warming simulations, we quantify the probability of similar “hiatus-like” periods occurring on a warmer globe. To that end employ various metrics and detrending techniques including EOF decomposition, running climatologies, along with linear and nonlinear trends to elucidate how natural variability changes over time. We also examine the changing influence of natural modes of variability with respect to the anthropogenic radiative forcing over different regions on the globe.Results suggest that natural variability for much of the global oceans decreases as the radiative forcing increases in the future warming scenarios.

▼ With each new generation of IC process technologies, the impact of manufacturing variability is increasing. As such, design optimality is harder and harder to achieve and effective modeling tools and methods are needed to capture the effects of variability in such a way that it is understandable and useful to IC designers. Our research has been stimulated by such needs and the goal of our work is to study and model the effect of manufacturing variations (systematic and random) on on-chip interconnects, and to make it transparent to designers. Specifically, we focus on interconnect capacitances. We propose a sensitivity-based modeling method and present a fast algorithm for sensitivity computation. The algorithm is applicable for layout parasitics extraction (LPE) tools based on a boundary element method (BEM). It is efficient in the sense that both the nominal values of capacitances and their sensitivities with respect to multiple parameters can be obtained with only one system solve. Such an algorithm forms a core of other algorithms for handling various aspects of variability-related problems in practice. Two extension algorithms have been developed in this thesis. The first extension provides a technique for computing the statistical properties of interconnect capacitances resulting from line-edge-roughness (LER). Using the proposed algorithm, the nominal values of capacitances as well as their statistical properties accounting for both the systematic and the random variations can be obtained at a negligible extra computational time, compared to the nominal capacitance computation. The fast estimate of LER effects on interconnect capacitances can be very useful for designs of passive components with high-precision requirements. In this context, a real design case is studied. Supported by the measurement results on test chips, our technique successfully estimates the mismatch of capacitances due to LER. Calculating the statistical properties of capacitances is, in many cases, not the eventual purpose of modeling manufacturing variabilities. Instead, it is the circuit performance, e.g. the system response, that designers care about. Traditionally, the statistical properties of the system response are obtained by the Monte-Carlo approach, which, however, suffers from a huge computational burden due to the need of sampling the parameter space. This problem can be solved by the second extension algorithm, which achieves zero parameter sampling, by combining the proposed sensitivity-based parameterized parasitics extraction technique and a structure-preserving parameterized model order reduction technique. It demonstrates a highly efficient methodology to obtain the statistical properties, such as the mean and the standard deviation, of the system response of RC nets subject to systematic variations. The proposed algorithm for the sensitivity computation has been implemented in a layout-to-circuit parasitics extractor SPACE. Advisors/Committee Members: Dewilde, P.M., Van der Meijs, N.P..

▼ Congestion on the Dutch motorway network is an actual problem, which originated over the past decades. Over the past few years, the extent of congestion is decreasing, though still very significant. Road authorities therefore show interest in traffic congestion forecasting. In this way they can inform road users or undertake other strategic actions. This thesis is therefore dedicated to the variability of traffic in congestion forecasting. The main objective is to develop a methodology operationalized in a model, which is able to predict congestion on motorways without knowledge of the actual traffic conditions. The model takes the variability of traffic into account and is substantiated with a solid theoretical framework relating the predictability of factors and their effects to traffic supply and demand. To fulfill this objective, a literature research has been conducted on traffic flow theory, factors and effects influencing traffic demand and traffic supply, model approaches and probabilistic methods. The identified influence factors are listed below: regular pattern of variation in human travel behavior over the day, over the days of the week and over the periods of the year; public holidays / vacation periods; events; weather conditions; road works; incidents; variations in vehicle population; variations in driver population; luminance; ‘intrinsic’ variations in driving behavior and in human travel behavior. Using the acquired knowledge a research methodology is developed. The model approach makes use of the basic principles of traffic flow theory based on the conservation of vehicles and first order traffic flow theory. To take the variability of influence factors into account, an intelligent sampling technique is used: Latin Hypercube Sampling. Before the model is constructed, the predictabilities and the effects of the various influence factors on traffic demand and traffic supply are described and explained through a theoretical framework. Some of them are always predictable (e.g. public holidays, luminance), while the predictability of others depend on data (e.g. road works or weather conditions). Incidents are considered not very predictable. The occurrence and therefore the effects of the identified influence factors can be continuously present or only on certain moments in time. They can also be on every cell of the motorway corridor or only on a selection of cells of the motorway corridor. The developed model makes use of traffic demand profiles and traffic supply variables. These are processed by a first order traffic model using a Godunov scheme. Traffic is numerically sent through the model subject to the defined boundary conditions. When the flow exceeds the capacity, congestion sets in and propagates backwards in space according to the first order traffic theory. From the modeled data, travel times and other performance indicators can be derived. A trajectory method is used to calculate the actual travel times. Before the model processes the traffic demand profile and traffic supply variables,… Advisors/Committee Members: Hoogendoorn, S.P. (mentor), Van Lint, J.W.C. (mentor), Goemans, J.W.

▼ The Indo-Pacific Ocean, particularly in Southeast Asia, directly affects an enormous coastal and island population, drives heat and moisture transfer across the globe, and provides a critical influence on future anthropogenic climate change. Natural variability in the climate system, acting in concert with global warming, leads to sea level changes that vary considerably across the region. Here we present three studies where sea level gradients in the Indo-Pacific are used to better understand variability and trends in global climate Satellite altimetry measurements have recently reached 25 years in length (1993 to 2017) providing a precise global sea level record to illuminate changes in ocean heat storage. The data shows that from 1993 to 2012 sea level in the western Pacific has risen up to four times faster than the global mean due to strengthening trade winds. To ensure robust results and extend the sea level record further our work includes data from state-of-the-art climate models, reanalysis products, sea level reconstructions, and ocean temperature databases. In Appendix A (published in Geophysical Research Letters), we quantify for the first time the relationship between fast sea level rise in the western Pacific and the observed slowdown of global average surface temperature from 1998-2012. In Appendix B (published in Water), we use the east-west sea level gradient in the Pacific as a metric for evaluating climate model skill in simulating variability. In Appendix C (in preparation for submission to Geophysical Research Letters), we show how the Indonesian Throughflow response to western Pacific sea level rise differs between reanalysis products and climate model simulations. In these three studies we utilize the newly available satellite altimetry record to better understand Indo-Pacific Ocean dynamics and how they are represented in the current generation of climate models.

▼ The Uintah and Ouray Reservation in northeastern Utah has not been widely studied, and access to non-tribal members is highly restricted. We sampled vegetation to summarize condition in 300,000 acres of unsurveyed Reservation lands in 2017-2018, combining these data with data collected by the Bureau of Indian Affairs from 2010-2015 to complete an initial rangeland vegetation inventory of the Reservation. This survey was designed to inform management of the area by determining cattle stocking rates and overall ecological condition across the Reservation. Both the density of forage available to cattle and appropriate cattle stocking rates vary greatly throughout management units in the Reservation. We also used the vegetation inventory data to run a model which estimates forage availability in every year from 1984-2018 throughout the Reservation. Whereas the initial inventory only considers the typical forage availability in management units, this method allows us to estimate how forage varies through space and time. The results show that forage availability varies significantly through time, declining and increasing by approximately one-third from median forage availability. Such variability indicates that typical forage availability, the measure used to determine stocking rates in the initial inventory, does not fully address forage availability dynamics. Since actual forage availability can be far lesser or greater than typical forage availability, stocking rates based on typical availability will often be an under or over estimation. The model results therefore lend a fuller picture of appropriate stocking rates. This may improve grazing management by revealing how much forage declines in unfavorable years such as during drought, and improving grazing planning during these years. The forage availability model can continue to be used in the future to monitor trends in vegetation over time, and the modeling method may be applicable to other similar study systems.

▼ The aging process is often coupled with major life changes such as retirement, death of friends and family members, and declines in physical and psychological functioning. Intuitively, any one or a conjunction of these events might be expected to lead to decreases in positive affect (PA) and increases in negative affect (NA). However, older adults tend to be emotionally positive and stable even late in life. Thus, it is possible that emotion-based strategies for coping with the challenges presented in later life can be used effectively by older adults, even amidst potential vulnerabilities in other domains. The design of effective interventions and technologies aimed at facilitating this coping process, will depend on understanding that emotions can influence health in different ways. Affect level and intraindividual variability (IIV) are independently related to distal factors such as personality and health-related outcomes such as immune functioning and mortality, among others. By nature, emotions are subject to daily fluctuations that cannot be captured by investigation of mean affect levels alone. Research on affect IIV has focused primarily on whether there are stability differences in younger and older adults. In general, older adults tend to be more stable, perhaps because the failure to regulate emotions is particularly detrimental for older adults’ physiological health. It is therefore important to understand how proximal factors in everyday life lead to intraindividual emotional changes. The primary goal of this study was to identify the factors occurring within older adults’ daily lives that predicted emotional deviations and to determine whether individuals differed in the types of factors that were emotionally-relevant. As such, it was imperative to employ a methodology that could differentiate the factors that evoked consistent emotional responses across all individuals from the factors whose impact on affect were person-dependent. Specifically, participants were given online surveys three times per day for 20 consecutive weekdays that included assessments of their current positive and negative emotional states and questions (at least once per day) about their stress, pain, sleep quality, life space, physical activity, and social activity. Multilevel modeling (MLM) was used to determine if there was significant affect IIV for these older adults and how much IIV could be explained by these proximal predictors. This analysis approach was used because it is well-suited for nested data (in this case, observations nested within-persons) and does not assume independence of observations (which is a concern when individuals receive repeated assessments). Additionally, MLM analyzes the complete dataset rather than complete cases (individuals), which allowed for comparison of fixed effects regression models and random effects regression models. Random effects models, which are the hallmark of MLM, enabled the analysis of potential individual differences in the within-person relationships between the… Advisors/Committee Members: Rogers, Wendy A.

▼ Semiconductor technology has been scaling down at an exponential rate for many decades, yielding dramatic improvements in power, performance and cost, year after year. Today’s advanced CMOS transistors have critical dimensions well below 24nm. This means that controlling the manufacturing process is increasingly difficult. Process and material fluctuations cause device and circuit characteristics to deviate from design goals, and introduce significant device-to-device variability due to spatial variations across silicon wafers. Accurate modeling of these spatial process variations has become critical to both foundries and circuit designers that seek optimal power/speed/area balance. To understand the nature of spatial process variations, we first carried out a comprehensive variability analysis of data measured from thousands of variability-sensitized test structures, including ring oscillators, SRAM bit cells and their internal transistors. We manufactured these test chips using early stage 90nm and 45nm commercial semiconductor processes. We proposed a hierarchical variability model to capture the systematic and random components of device parameter variations across silicon wafers, and across chips. The detailed decomposition of the process variation profile reveals significant across-wafer systematic component for the delay and leakage of ring oscillators, and across-chip systematic component for the read/write margins of SRAM bit cells, as well as their internal transistors. The proper modeling of each hierarchical component proved to be crucial for the accurate estimation of the statistics of device performance distribution and its parametric yield.The knowledge gained about process variation from carefully designed test structures was leveraged into estimating the variation and parametric yield of new devices and circuits. This was accomplished by improved the statistical compact model parameter extraction methodology, and by proposing a stepwise parameter selection method. We used a normalized notional confidence interval and, and the sum of squares of fitting residuals as extraction and fitting quality criteria. This allowed us to determine the essential model parameters for accurate fitting over a large number of transistors. We applied this methodology to EKV and PSP with both simulated and experimental data, demonstrating its effectiveness. Finally, we combined the results from statistical parameter extraction with the hierarchical spatial variability model. This, compared to traditional methods, produced much-improved estimates of device performance and manufacturing yield.

▼ Continued scaling of semiconductor technology has greatly increased the complexity of the manufacturing process, and Design for Manufacturing (DFM) has emerged as an important topic of research over the last decade. DFM strives to reduce variability in Integrated Circuits through extensive modeling and analysis of process induced variability. This dissertation focuses on modeling, analysis and optimization techniques to manage variability within IC design. This dissertation begins with proposing the use of so called soft-edge flip-flops with a small window of transparency, instead of a hard edge for capturing data. Soft edge flip-flops allow time borrowing and averaging across stages, making the design less sensitive to process variations. Next four chapters model the layout dependence of mechanical stress and explore techniques to exploit the layout dependencies of mechanically stressed silicon through mechanical stress aware design and optimization. Chapter 3 uses mechanical stress aware standard cell library design in conjunction with dual threshold voltage (Vth) assignment to achieve optimal power-performance tradeoff, and decrease leakage power consumption by ~24%. Chapter 4 discusses a standard cell library design technique called STEEL. Chapter 5 presents compact closed-form models for layout dependence of process induced stress, and its impact on carrier mobility. Chapter 6 proposes a technique to model non-rectangular gates (NRG) with non-uniform carrier mobility to enable accurate prediction of both device drive current and leakage. Next chapter studies the impact of Rapid Thermal Anneal (RTA) temperature variation on circuit timing and leakage, and proposes techniques to minimize the impact of anneal temperature variation. Chapters 8 and 9 show significant impact of different Double Patterning Lithography (DPL) techniques on Static random-access memory (SRAM) robustness through measurement and simulation, and propose DPL-aware sizing optimization of SRAM cell. Experimental results based on 45nm industrial models show that using the best DPL option for each layer, along with the sizing optimization presented, can achieve single exposure robustness together with improved DPL printability at nearly no overhead. Finally, a framework that captures through-silicon via (TSV) induced mechanical stress and its impact on device mobility is discussed, and TSV stress is shown to cause delay variations of up to 6.9%.

▼ Despite the immense impacts that large, modern North American droughts, such as those of the 1930s and 1950s, had on economic, social, environmental, and agricultural systems, they were ultimately shorter in duration than the multidecadal to centennial scale megadroughts that affected North America, in particular the western United States,during the Medieval Climate Anomaly (MCA, ~ 850-1300 AD)and the Little Ice Age (LIA, ~1450-1850 AD. Although various proxy records have been used to reconstruct the timing of these MCA and LIA megadroughts in the western United States, there still exists great uncertainty in the magnitude and spatial coherence of such droughts in various cross sections of western North America (i.e. the Pacific Northwest region),especially on decadal to centennial timescales. This uncertainty motivated the following study to establish a causal link between the climate forcing that induced these megadroughts and the spatiotemporal response of regional North American hydroclimates,such as those of the Pacific Northwest, American Southwest, and the Great Plains,to this forcing. This study seeks to establish a better understanding of the influence of tropical Pacific,tropical Indian, extratropical North Pacific, and North Atlantic sea surface temperatures (SSTs) on North American drought during the MCA (950-1250 AD) and LIA (1400-1700 AD). We force NCAR’s Community Atmosphere Model version 5.1.1 (CAM 5), as part of a special configuration of the fully coupled Community Earth Systems Model version 1.0.5 (CESM 1.0.5), with prescribed proxy-reconstructed tropical Pacific, tropical Indian, extratropical North Pacific, and North Atlantic SST anomalies from the MCA and LIA, in order to investigate the influence that these SST anomalies had on the spatiotemporal patterns of drought in North America. To isolate the effects of individual and multiple ocean basin SSTs on the North American climate system, the conducted model experiments use a variety of SST permutations in the tropical Pacific, tropical Indian, extratropical North Pacific, and North Atlantic basins as climate forcing. In order to quantify the spatiotemporal response of the western North American hydroclimate system to these SST forcing permutations, precipitation data derived from the MCA and LIA model experiments are presented here as MCA anomalies relative to the LIA reference period. The spatiotemporal precipitation patterns from the model experiments indicate that in the Pacific Northwest, the MCA and LIA were anomalously wet and dry periods, respectively, a finding that is largely supported by the available lake sediment proxy records. This pattern contrasts with the dry MCA/wet LIA pattern diagnosed in model experiments for the U.S. Southwest and Great Plains regions and indicated by tree ring-based proxy data. Thus, the CAM 5 model experiments confirm the wet/dry meridional precipitation dipole pattern suggested by proxy data for the western U.S. during the MCA and LIA and highlight the role that the natural variability of tropical… Advisors/Committee Members: Michael Mann, Thesis Advisor/Co-Advisor.

▼ The massive amount of current data has led to many different forms of data analysis processes that aim to explore this data to uncover valuable insights such as trends, anomalies and patterns. These processes support decision makers in their analysis of varied and changing data ranging from financial transactions to customer interactions and social network postings. These data analysis processes use a wide variety of methods, including machine learning, in several domains such as business, finance, health and smart cities. Several data analysis processes have been proposed by academia and industry, including CRISP-DM and SEMMA, to describe the phases that data analysis experts go through when solving their problems. Specifically, CRISP-DM has modeling as one of its phases, which involves selecting a modeling technique, generating a test design, building a model, and assessing the model. However, automating these data analysis modeling processes faces numerous challenges, from a software engineering perspective. First, software users expect increased flexibility from the software as to the possible variations in techniques, types of data, and parameter settings. The software is required to accommodate complex usage and deployment variations, which are difficult for non-experts. Second, variability in functionality or quality attributes increases the complexity of these systems and makes them harder to design and implement. There is a lack of a framework design that takes variability into account. Third, the lack of a more comprehensive analysis of variability makes it difficult to evaluate opportunities for automating data analysis modeling. This thesis proposes a variability-aware design approach to the data analysis modeling process. The approach involves: (i) the assessment of the variabilities inherent in CRISP-DM data analysis modeling and the provision of feature models that represent these variabilities; (ii) the definition of a preliminary framework design that captures the identified variabilities; and (iii) evaluation of the framework design in terms of possibilities of automation. Overall, this work presents, to the best of our knowledge, the first approach based on variability assessment to design data modeling process such as CRISP-DM. The approach advances the state of the art by offering a variability-aware design a solution that can enhance system flexibility and a novel software design framework to support data analysis modeling.

▼ Terrain-induced gravity waves and rotor circulations have been hypothesized to enhance the generation of submeso motions (i.e., nonstationary shear events with spatial and temporal scales greater than the turbulence scale and smaller than the meso-gamma scale) and to modulate low-level intermittency in the stable boundary layer (SBL). Intermittent turbulence, generated by submeso motions and/or the waves, can affect the atmospheric transport and dispersion of pollutants and hazardous materials. Thus, the study of these motions and the mechanisms through which they impact the weakly to very stable SBL is crucial for improving air quality modeling and hazard predictions. It is important to note that while gravity waves and rotors have been thoroughly studied through theoretical, observational, and idealized modeling studies, little still is known about the response of nonstationary and nonlinear waves for real cases under typical SBL conditions, and about the impact of different wave behaviors on rotor development and evolution, and the generation of intermittent low-level turbulence. Consequently in this thesis, the effects of waves and rotor circulations on submeso and turbulence variability within the SBL is investigated over the moderate terrain of central Pennsylvania using special observations from a network deployed at Rock Springs, PA and high-resolution Weather Research and Forecasting (WRF) model forecasts. The investigation of waves and rotors over central PA is important because 1) the moderate topography of this region is common to most of the eastern US and thus the knowledge acquired from this study can be of significance to a large population, 2) there have been little evidence of complex wave structures and rotors reported for this region, and 3) little is known about the waves and rotors generated by smaller and more moderate topographies. Six case studies exhibiting an array of wave and rotor structures are analyzed. Observational evidence of the presence of complex wave structures, resembling nonstationary trapped gravity waves and downslope windstorms, and complex rotor circulations, resembling trapped and jump-type rotors, is presented. These motions and the mechanisms through which they modulate the SBL are further investigated using high-resolution WRF forecasts. First, the efficacy of the 0.444-km horizontal grid spacing WRF model to reproduce submeso and meso-gamma motions, generated by waves and rotors and hypothesized to impact the SBL, is investigated using a new wavelet-based verification methodology for assessing non-deterministic model skill in the submeso and meso-gamma range to complement standard deterministic measures. This technique allows the verification and/or intercomparison of any two nonstationary stochastic systems without many of the limitations of typical wavelet-based verification approaches (e.g., selection of noise models, testing for significance, etc.). Through this analysis, it is shown that the WRF model largely underestimates the number of small amplitude… Advisors/Committee Members: David R Stauffer, Dissertation Advisor/Co-Advisor, George Spencer Young, Committee Member, Fuqing Zhang, Committee Member, Jacob Willem Langelaan, Committee Member.

Programų sistemų kūrimas, kai yra daug užsakovų, kurių reikalavimai skiriasi, yra sudėtingas procesas ir reikalauja aprašyti galimus programų sistemos variantus. Programų variantiškumui aprašyti naudojami kuriamos sistemos požymių modeliai. Sistemos požymių modeliavimas yra svarbus variantiškumo aprašymo metodas. Sistemos požymių variantiškumo modeliai aprašo aibę programų sistemų, kurios dar vadinamos programų sistemų linija. Programų sistemų linija yra eilė panašių programų kurios dalinasi bendrais atributais. Tiksliau apibūdinti programų sistemų linijai yra nustatomi sistemų atributai ir jų tarpusavio sąryšiai, jie yra pavaizduojami požymių diagramose. Požymis tai savitas, charakteringas sistemos atributas, kuris nusako matomus sistemos atributus, tačiau nesigilina į detalų sistemos apibūdinimą. Greitam ir kokybiškam programų sistemos variantiškumo modeliavimui reikalingas geras įrankis. Tam skirtas požymių diagramų modeliavimo įrankis, nes sukurti požymių modeliai yra informatyvūs ir gali lengvai perteikti sistemos variantiškumo informaciją. Tačiau programų sistemos požymių diagrama neturi techninės informacijos, kuri yra reikalinga programos kūrimui. Ši informacija yra saugoma UML modeliuose. Programos UML modelį galima išplėsti variantiškumo informacija, papildant jį sistemos požymių modelio informacija. Magistrinio projekto metu buvo sukurtas įrankis (FD2), kuris įgyvendina požymių diagramos susiejimą su UML klasių diagrama. Magistriniame darbe tiriamas sistemų... [toliau žr. visą tekstą]

Feature modeling is important approach to deal system variability at higher abstraction level. Variability models define the variability of a software product line. Unfortunately, it is not integrated into a modeling framework like the Unified Modeling Language (UML). To use it in conjunction with UML, it is important to integrate feature modeling into UML. This thesis describes the way how feature variability models can be linked with existing UML models and how it is done in the feature modeling tool FD2. The feature modeling tool is described and the complete example provided. Chapter 2 discusses the way of Feature model integration with UML model. Chapter 3 describes the implementation of FD2 tool. Chapter 4 discusses the advantages and disadvantages of FD2 tool. Chapter 5 provides examples and discusses their results. In conclusion this thesis propose feature modeling integration with UML modeling, discusses the program developed during master project, provides 2 examples and discusses their results, points out some issues requiring further work.

▼ Le bassin méditerranéen est sujet à de nombreuses sources d'aérosols présentant une variabilité spatio-temporelle élevée. Ces aérosols interagissent de manière directe avec les rayonnements solaire et thermique, et de manière indirecte avec les nuages et la dynamique atmosphérique. Ils peuvent donc avoir un impact important sur le climat de cette région. Ce travail de thèse, à la frontière entre les projets HyMeX et ChArMEx, considère une approche par la modélisation régionale couplée pour répondre aux questions des interactions aérosols-rayonnement-nuages par rapport à la variabilité climatique de la région méditerranéenne. Afin de mieux caractériser les aérosols méditerranéens, une nouvelle climatologie mensuelle et interannuelle d'épaisseur optique a été développée à partir d'une combinaison de produits satellites et de modèles. Ce jeu de données, disponible pour tous les modèles régionaux de climat en Méditerranée sur la période 1979-2012, a été mis au point dans le but d'obtenir la meilleure estimation possible du contenu atmosphérique en aérosols pour les cinq types considérés (sulfates, carbone suie et organique, poussières désertiques et sels marins). Des ensembles de simulations réalisées sur la période 2003-2009 avec et sans aérosols montrent un impact majeur sur le climat régional. Cet impact se caractérise par un forçage radiatif négatif en surface (dû à la diffusion et l'absorption du rayonnement solaire incident) de -15 W.m−2 en moyenne annuelle sur la mer Méditerranée, par un refroidissement induit en surface à la fois sur mer et sur terre de l'ordre de 0.5◦C en moyenne annuelle, par une diminution moyenne des précipitations ainsi que par des changements de nébulosité. Le cycle saisonnier et les structures spatiales du climat méditerranéen sont ainsi significativement modifiés, ainsi que certaines situations spécifiques comme la canicule de juillet 2006 qui a été renforcée par la présence d'aérosols désertiques. Le rôle essentiel de la température de surface de la mer Méditerranée dans la réponse du climat aux aérosols est mis en évidence, et permet de comprendre les modifications induites des flux air-mer (notamment la diminution de la perte en chaleur latente) et ses conséquences sur le climat régional. La convection océanique en mer Méditerranée est également renforcée par la présence d'aérosols. En outre, on démontre que la diminution des aérosols anthropiques observée depuis plus de trente ans a contribué significativement aux tendances climatiques de rayonnement (représentant 81 ± 15 % de l'éclaircissement) et de température (représentant 23 ± 5 % du réchauffement) observées en Europe et en Méditerranée. D'autre part, un schéma interactif d'aérosols a été mis en place dans le modèle atmosphérique ALADIN-Climat afin de pouvoir comprendre les processus liés aux aérosols à l'échelle quotidienne. On montre ici la capacité de ce schéma de simuler de manière réaliste les aérosols présents en Méditerranée, notamment dans le cas des intrusions de poussières désertiques observées pendant la campagne de… Advisors/Committee Members: Déqué, Michel (thesis director), Somot, Samuel (thesis director).

▼ The Madden-Julian Oscillation (MJO) is the leading source of predictability on seasonal and subseasonal scales in the tropics, and is one of the least understood phenomena of tropical meteorology. Although extensive research has been done on the topic of MJO initiation and its eastward propagation, there is not a single widely-accepted theory that explains the phenomenon. The lack of understanding is reflected in the poor representation of the MJO in global and numerical weather prediction models. In this study, a regional, atmosphere-ocean coupled model is used to perform a series of high- and low- resolution experiments in coupled and uncoupled configurations to address the effects of moist physics, resolution, and atmosphere-ocean coupling on the simulation of MJO. As a case study, we use the second MJO event (MJO2) observed during the Dynamics of the MJO (DYNAMO) field experiment (October 2011 - March 2012). MJO2 is currently the best observed MJO event on record, and the copious amount of data collected by multiple observational platforms is used for model evaluation. We find that the MJO in the coupled model run at a relatively low resolution (12 km grid spacing) is very sensitive to the choice of convective parameterization, which does not only affect the amount and distribution of precipitation, but also influences the vertical structure of winds and relative humidity in the atmospheric boundary layer. Two convective parameterizations, with different triggering mechanisms for convection are considered, with one producing tropical cyclones, and the second one simulating an MJO, though not accurately representing individual features. When resolution is increased to a convection-permitting grid spacing (4 km resolution) in the coupled configuration, the representation of individual convective features improves regardless of the convective parameterization outside the high-resolution domain. A high precipitation bias is present in all experiments and can be linked to a high bias in the surface-layer air-sea flux parameterization, and a positive bias in the ocean mixed layer depth. Reducing the air-sea flux bias through a modification of the buoyancy-driven turbulence parameterization for air-sea fluxes succeeds at reducing the precipitation bias and improves (weakens) the surface winds, and enhances the representation of MJO’s eastward propagation. With weaker surface winds, the ocean cooling is reduced, which slightly offsets the introduced modification. The high-resolution uncoupled experiment (atmosphere only) does not produce an MJO - it produces excessive precipitation that is present throughout the 15-day simulation and extends eastward from the Indian Ocean, but never propagates out of it. The study concludes that high (cloud-permitting) resolution is integral in accurately representing the precipitation features associated with the MJO, and the MJO-induced upper-ocean cooling in atmosphere-ocean coupled experiments is essential for the MJO’s eastward propagation.

▼ Service Oriented Architecture (SOA) has emerged as an architectural style for distributed computing that promotes flexible application development and reuse. One of the major benefits claimed for SOA is the flexible building of IT solutions that can react to changing business requirements quickly and economically. Services could be consumed by many applications that have different requirements. In addition, applications usually change by adding new requirements, removing existing requirements, or updating existing requirements. Thus, applications that consume the same service usually exhibit varying requirements. Varying requirements usually necessitate varying software architectures that satisfy the varying requirements of software applications. Thus, both requirements and architectures have intrinsic variability characteristics. SOA development practices currently lack a systematic approach for managing variability in service requirements and architectures. This dissertation addresses this gap by applying software product line (SPL) concepts to model SOA systems as service families. The dissertation introduces an approach to model SOA variability with a multiple-view service variability model and a corresponding meta-model. The approach integrates SPL concepts of feature modeling and commonality/variability analysis with multiple service requirements and architectural views by using UML and the Service Oriented Architecture Modeling Language (SoaML). At the heart of this research is a multiple-view meta-model that defines the relationships among variable service views and maps features to variable service models along with a corresponding consistency checking rules that ensure the consistency of the multiple service views as they change. The dissertation describes how to derive family member applications from the SPL and presents a validation of the approach. This dissertation makes the case that the presented multiple-view service variability modeling and meta-modeling approach facilitates variability modeling of service families in a systematic and platform independent way. The key contributions of this research include: Multiple-View Service Variability Meta- Model, Multiple-View Service Variability Model, Consistency Checking and Mapping Rules, Model Driven Framework for Service Oriented SPL Engineering, Service Member Applications Derivation Rules, Explicit Modeling of Service Coordination Variability, and a Proof-of-Concept Tool Prototype.S Advisors/Committee Members: Gomaa, Hassan (advisor).

L’industrie microélectronique arrive à concevoir des transistors atteignant dimensions de l’ordre de la dizaine de nanomètres. Et ce faisant elle tend atteindre ses limites en terme de réduction des dimensions des transistors CMOS. Or à ces dimensions, la fiabilité et la variabilité des dispositifs prennent une ampleur critique en ce qui concerne les prédictions de durée de vie et de garantie des composants. Parmi les aspects critiques, la dégradation NBTI (Négative Bias Temperature Instability) représente l’un des plus gros défis en termes de fiabilité. Cette dégradation tire son origine d’un piégeage de charge dans l’oxyde de grille et est responsable pour une grande partie de la dégradation des transistors. A l’aide d’un important travail expérimental, nous avons caractérisé à l’aide de mesure rapide les cinétiques de dégradation et de relaxation de la dégradation NBTI, puis nous avons travaillé sur la modélisation des phases de stress et de relaxation. Nous sommes parvenues à créer un modèle pour le stress et la relaxation que nous avons éprouvé sur un certain nombre de nœuds technologiques allant du 14nm FDSOI au 180nm Bulk. Nous avons aussi évalué l’impact de certains changements de procédées de fabrication sur la dégradation NBTI.Enfin nous proposons une étude poussée de la variabilité induite par le NBTI et du modèle DCM (Defect centric Model) permettant de modéliser cette variabilité. Nous proposons alors une correction mathématique de ce modèle, et la possibilité de le réécrire afin de pouvoir l’utiliser pour un plus grand nombre de défauts. Enfin nous mettrons ce modèle en échec sur les prédictions qu’il fait de défauts et nous proposons un nouveau modèle sous la forme d’un DCM à deux défauts ou DDCM (Dual Defect Centric Model).Mots-clés : Microélectronique, FDSOI, Bulk, variabilité, NBTI, caractérisation électrique, modélisation.

The microelectronics industry is able to design transistors reaching dimensions of the order of ten nanometers. And doing this, we reaching the limits in terms of size reduction of CMOS transistors. At these dimensions, the reliability and variability of the devices is critical in terms of lifetime prediction and component warranty. Among the critical aspects, NBTI (Negative Bias Temperature Instability) degradation represents one of the biggest challenges in terms of reliability. This degradation coming from a charge trapping in the gate oxide is responsible for a large part of the degradation of the transistors. Performing a huge experimental work based on the characterization of the kinetic of degradation and relaxation of the NBTI degradation with rapid measurements, allowing us to work on the modeling of the stress and relaxation phases of NBTI degradation. We have successfully create a model for stress and relaxation of the NBTI degradation. These models were then tested on several technological nodes from 14nm FDSOI to 180nm Bulk. We also study the impact of some process changes on NBTI degradation. Finally, we propose a detailed study of the variability induced by the…

▼ Les systèmes et applications microélectroniques sont présentes partout dans notre civilisation humaine d’aujourd’hui, depuis le plus simple appareil de notre vie quotidienne jusqu’à des vaisseaux/robots spatiaux qui nous permettent d’observer des images des mondes lointains du Système Solaire et au-delà. L’industrie du semi-conducteur est devenue, depuis sa naissance dans les années 1960, l’une des plus grandes d’aujourd’hui et qui connait une croissance continue avec environ 350 milliards de dollars de chiffre d’affaires annuel. Le composant de base de la microélectronique est le transistor, qui depuis sa conception il y a environ 50 ans a subit une évolution impressionnante en termes de performances, coût et densité d’intégration, cette évolution a été soutenue par des investissements économiques et humains pour suivre ladite « Loi de Moore », qui prédit une augmentation du double de composants intégrés dans une puce tous les deux ans. Le Transistor à Effet de Champ Métal/Oxyde/Semi-conducteur (Metal-Oxide-Semiconductor Field-Effect Transistor, MOSFET en anglais) est devenu le composant préféré pour les applications numériques dans l’industrie. Avec la miniaturisation du transistor, l’un des grands défis est de limiter l’impact de la variabilité du transistor, qui devient de plus en plus important lorsqu’on diminue les dimensions du composant. Deux transistors dessinés et fabriqués de manière identique peuvent présenter des caractéristiques très différentes; lorsque cette variabilité est de nature systématique, on peut trouver souvent un moyen technologique pour l’éliminer ou on peut modéliser les effets de manière très précise, ce qui n’est pas le cas lorsque la variabilité est de nature statistique, ce type de variabilité est de nature aléatoire et résulte de la nature granulaire de la matière et la difficulté de contrôler le positionnement des atomes, un-par-un, à un niveau industriel. Il est donc nécessaire de caractériser et modéliser la variabilité local statistique pour permettre de mieux prédire les effets indésirables dans des circuits complexes dus à ce type de variabilité et donc de mieux concevoir les produits pour qu’ils soit le plus robustes. Le but de ce projet est d’aller plus loin dans la manière d’appréhender la variabilité et de revisiter les moyens de caractérisation de la variabilité du MOSFET, développer des méthodes d’analyse de données pour extraire le maximum d’information pertinente sur les sources de variabilité et leur impact dans les performances des composants, le tout basé sur des données expérimentales obtenues sur des structures de test améliorées. L’un des points clés de notre méthode de caractérisation de la variabilité développée dans ce projet, est de permettre une modélisation statistique précise des variations du procédé de fabrication et leur impact dans l’environnement design; pour réussir notre objectif, les méthodes développées doivent fournir des paramètres statistiques avec un intervalle de confiance bien établi, et qui peuvent être implémentés dans des modèles… Advisors/Committee Members: Ghibaudo, Gérard (thesis director).

▼ Mountain snowpacks vary drastically over length scales as small as 1—2 meters in complex terrain and require high resolution measurements to accurately quantify the spatial distribution of snow. This thesis explores this spatial distribution using remote sensing, modeling and ground-based observations. Snow depth estimates from airborne LiDAR at 5 m resolution over 750 km2 was compared to in situ observations and results from physically-based snow and wind redistribution models, and a new low cost method for continuous depth measurements at the slope scale was developed. Repeated airborne Light Detection And Ranging (LiDAR) surveys are capable of recording snow depth distributions at 1—5 meter resolution over very large geographic areas, while additionally providing information about vegetation, slope aspect and terrain roughness. During NASA's second Cold Lands Processes eXperiment (CLPX-II) in the winter of 2006/07, two LiDAR surveys were flown nearly three months apart over a vast 750 km2 swath of the Rocky Mountains near Steamboat Springs, Colorado. Both flights took place well before any significant melt occurred, and the difference of the vegetation-filtered surfaces resulted in an estimate of the change in snow height across the survey area. An intensive manual measurement campaign was conducted to coincide with each LiDAR flight to provide ground truth information for the LiDAR dataset. Using the in situ measurements and the LiDAR-derived snow depth changes, an uncertainty study was performed to investigate errors in snow depth change for this high resolution remote sensing method due to elevation gradients and vegetation types. Secondly, this work leverages the large extent of the CLPX-II LiDAR dataset to validate more than 900 pixels, each at 30 arc-second resolution, of modeled snow depth from the SNOw Data Assimilation System (SNODAS) operational hydrologic model developed by the National Operational Hydrologic Remote Sensing Center (NOHRSC). Upscaling the high resolution LiDAR-derived snow depths to the much lower spatial resolution of the SNODAS estimates produced a statistically robust dataset of over 900 independent pixel comparisons for the first time, due to the difficulty in obtaining independent validation data at the 1 km scale. Results support the notion that sub pixel-scale slope, aspect, vegetation density and terrain rough- ness factors are important to consider for model predictions of snow distribution in mountain regions. To investigate the wind transport factor, a wind redistribution model based on terrain characteristics is implemented for a 1 km2 wind-affected sub region where high resolution snow depths have been supplied from three independent LiDAR flights taken during different winter seasons. The inter-annual consistency of snow depths at the site reveals a close correlation with the terrain parameters produced by the wind model for a known local prevailing wind direction. LiDAR currently remains the highest resolution large extent method for measuring snow depth, even though it is…

▼ Northeast Puerto Rico is home to a wide range of terrestrial and aquatic climate-sensitive ecosystems. Climate disturbances such as extreme events (e.g. hurricanes) and drought have cascading impacts on the biota. The biota responds to changes in precipitation variability on daily and sub-daily time scales. As a result, high temporal and spatial resolution climate data are needed to adequately assess climate impacts on the ecological process occurring in the region. This dissertation analyzes past, present, and future precipitation variability at a highly localized scale in northeast Puerto Rico. Additionally, a more comprehensive understanding of the regional climate forcing on precipitation variability is achieved. Artificial neural networks are used to downscale synoptic scale atmospheric variables to precipitation. These tools allow for modeling precipitation and determining the atmospheric processes driving precipitation variability This dissertation finds that precipitation throughout Puerto Rico is driven primarily by variability in specific humidity and wind shear in the low-troposphere. The driest daily precipitation in northeast Puerto Rico is observed in synoptic environments with high wind shear and low moisture at 700 hPa. Both of these atmospheric variables are driven by changes in the north Atlantic sea-surface temperature, the Saharan Air Layer, and the North Atlantic Subtropical High. The historical record shows little linear trend in total precipitation, however, precipitation variability is shown to be changing especially during the early rainfall season. It is posited that this increase in variability could be in part due to changes in the mechanisms driving the Caribbean Mid-Summer Drought. Future precipitation in northeast Puerto Rico is likely to be more variable with an overall drying trend. The highest magnitude changes are expected to occur in the early rainfall season as the trade wind inversion strengthens and wind shear across the region increases. These changes will cause disruptions to precipitation processes across several scales of motion, from tropical storm development to deep, moist convection. These trends in precipitation will likely cause significant impacts to the ecosystems of northeast Puerto Rico.
