▼ Significant amounts of uncertainty owing to both modeling decisions and inher-
ent randomness are present in simulating the material and geometric nonlinear
response of structural systems to extreme loading. Computing the
sensitivity of
structural response with respect to model parameters indicates which parameters
have the largest affect on the response, which can in some cases be more important
to an engineer than only the deterministic response. Considering the large num-
ber of parameters in a structural model, accurate and efficient response
sensitivity
computations, or gradients of the structural response, are required for nonlinear
structural reliability, optimization, and system identification analyses. Response
sensitivity for geometric nonlinear finite element analysis are presented including a
geometrically-nonlinear displacement based-beam column element formulation, the
displacement control nonlinear static solution method, and the corotational trans-formation of space frame finite elements. The direct differentiation method (DDM)
is used to derive the response
sensitivity equations for the aforementioned formu-
lations. The response
sensitivity equations for geometric nonlinear displacement-
based beam-column element are formulated in the deformed configuration using
Lagrangian strain. The derivation of the
sensitivity equations for the displace-
ment control solution method is performed according to an incremental-iterative
solution strategy. The
sensitivity equations of space frame formulations require
the derivative of the system triads in the deformed configuration according to the
corotational theory and the numerical algorithms for its implementation in a finite
element setting.
The derived equations are implemented in the OpenSees software framework.
To verify the accuracy of the derived equations, standalone
sensitivity analysis
is performed by comparing the response
sensitivity results obtained by the DDM
with those obtained by the finite difference method (FDM). The standalone sen-
sitivity analysis is performed for different element, material, and section models.
Furthermore, the response
sensitivity equations are utilized to perform reliabil-
ity and ranking of importance measures for complex steel and reinforced concrete
structures.

▼ In a proper circuit design procedure, it is important to consider the performance of a circuit when its elements are expected to vary from their nominal values due to various internal and external factors. Performing a
sensitivity analysis on circuit provides deep insight to such a requirement.
The conventional
sensitivity analysis methods catering power electronic circuits need lengthy and computationally demanding simulation effort when the circuit is complex and the number of circuit elements involved is large.
This thesis presents a computationally efficient
sensitivity analysis method which utilizes the salient feature of network-based
sensitivity analysis methods, i.e. less simulation effort. To overcome the applicability limitations of network-based methods on complex power electronic circuits, the proposed method performs
sensitivity analysis on linearized average model of the circuit instead of its original circuit.
The resulting sensitivities derived from proposed method were validated against those derived from a conventional method.

▼ The physical environment affects every individual differently, however past research suggests that certain individuals exhibit a greater susceptibility to environmental factors than the general population (Jawer, 2006). According to Jawer (2006) these environmentally sensitive individuals are also significantly more likely to report paranormal experiences than non-sensitives. The current study set out to test the hypothesis that environmentally sensitive individuals will report more past paranormal experiences as well as more haunt-type experiences in a natural setting. The study also looked at whether subtle differences in electromagnetic fields (EMFs) led to an increase in reported haunt-type experiences among sensitives. Methods: Participants (N=251) completed a questionnaire which categorized them as either environmentally sensitive or non-sensitive and were then led on a guided tour of an allegedly haunted location where they reported any unusual phenomena that they experienced. EMF readings were taken of the rooms visited on the tour and based on those readings the rooms were either designated as ‘High EMF’ rooms or ‘Low EMF’ rooms. Results: Sensitives reported significantly more past paranormal experiences and haunt-type experiences in a natural setting. Overall there were significantly more haunt-type experiences in ‘High EMF’ rooms than ‘Low EMF’ rooms suggesting an association between increased EMFs and reports of haunt-type experiences. Further analysis showed that sensitives reported significantly more haunt-type experiences in ‘High EMF’ rooms than ‘Low EMF’ rooms; however there was no significant difference in reported experiences between rooms among non-sensitives which suggests that sensitives could be picking up on subtle EMF differences leading to an increase in reports of haunt-type experiences.

▼ In this work we consider the dependence of solutions to a partial differential equations system on its data. The problem of interest is a coupled model of nonlinear flow and transport in porous media, with applications, e.g. to environmental modeling. The model of flow we consider is known as the non-Darcy model, and its solutions: the velocity, and pressure unknowns, depend on the coefficients of permeability and inertia, and other data such as boundary conditions. In turn, the transport solutions depend on the velocity of the fluid, and on boundary and initial conditions. Furthermore, one can be interested in a particular quantity computable from the flow and transport solutions, and represented by a functional. In this work we evaluate rigorously the
sensitivity, i.e., the derivative, of the solutions, or of the quantity of interest, upon the data.
Due to its delicate nature, the
sensitivity is evaluated either in a direct way, called Forward
Sensitivity, or via an adjoint method, which only uses a variational form. Our first contribution is that we find a way to find the
sensitivity for the coupled flow and transport model without having to solve multiple flow problems. Second, we prove the well-posedness of the flow problem, and set up the numerical approximation using the framework similar to that of expanded mixed finite element methods.
Next, the numerical approximation of the problem leads to a nonlinear system of discrete equations, which is difficult to solve. To aid in solving this system, we propose to take advantage of
sensitivity analysis, which is used in a novel way within a homotopy framework. The theoretical results in this thesis are illustrated with numerical simulations. The code, in Python, for the examples is provided.

▼ Recently, pavement design has changed from old method based on empirical relation to a new method called Mechanistic Empirical Pavement Design Guide (MEPDG). It is essential to perform a detailed
sensitivity analysis of MEPDG outputs to input variables. In particular, MEPDG inputs need to be classified based on their influence on MEPDG outputs for New Mexico pavement conditions. In this study,
sensitivity analyses are performed to identify a list of input variables that have significant impacts on the MEPDG outputs considering New Mexico pavement conditions.
Sensitivity analyses are performed in two steps. In the first step, a preliminary
sensitivity analysis is carried out by varying one input variable at a time while keeping the other inputs constant. The purpose of the preliminary
sensitivity analysis is to prepare a short-list of significant input variables out of more than hundreds of variables in MEPDG. In the second step,
sensitivity analyses are performed using advanced statistical approaches that consider interactions among the input variables. Parametric procedures such as tests for nonrandomness in scatterplots, linear and nonlinear regression analyses, and nonparametric procedures such as multivariate adaptive regression spline, gradient boosting machine are employed to identify and rank the significant input variables. Results show that predicted pavement performances are sensitive to traffic input variables such as Annual Average Daily Truck Traffic (AADTT) and percent of trucks in design lane. Both asphalt surface layer and total rutting are shown to be the most severe cases among all distresses for New Mexico pavements. Both AC and total rutting are highly sensitive to AADTT, percent of trucks in design lane, and bottom AC layer thickness. Outputs such as terminal IRI, longitudinal cracking, and alligator cracking are highly sensitive to bottom AC layer thickness. MEPDG outputs are also sensitive to HMA mix properties such as thickness, percent air void, binder content and PG grade. Longitudinal and transverse cracking are sensitive to base course material type, modulus and thickness. Depth of water table did not affect the MEPDG outputs at all. Transverse cracking and total rutting are sensitive to subgrade modulus, material properties, and gravimetric water content. MEPDG predicted outputs are found to be moderately sensitive to percent of trucks in design direction, traffic growth factor, and base thickness. Operational speed, depth of ground water table, and design lane width have very little to no effect to MEPDG predicted distresses. Finally, a list of significant variables is made for New Mexico pavement conditions. The list of significant inputs can be useful to pavement engineers to optimize pavement designs and analyze performances as well as for local calibration of MEPDG.

▼ To fulfill the ever-increasing energy demand and to curb the innumerable threats that conventional
energy generation techniques are posing, we are forced to explore the use of renewable
energy sources. The contribution of renewable energy sources in total primary energy consumption
has been steadily rising in the past few decades. The increased penetration of the renewable
energy sources into the power system network have provided enormous opportunities and their
own set of challenges to deal with. Hence, the study of various control strategies and their
performances employed to integrate the renewable energy sources to the existing power system
network is of prime importance. In this research, a novel technique is proposed to analyze the
performance of the close loop system used to integrate a renewable energy source to the power
system network.
A solar photovoltaic array connected to a load interfaced via a dc-dc converter is considered
as the test system in this research. An optimal control theory based linear quadratic regulator
(LQR) controller is designed for the closed loop operation of the system. Derivative based
sensitivity functions are formulated to validate the performance of the designed closed loop
controller. The contribution of closed loop controller to the stability and overall system response
is analyzed using the
sensitivity functions. The system characteristics such as settling time and
percent overshoot are modified to meet the desired requirements using the derived
sensitivity
functions. A simplified model of the system is built using MATLAB/Simulink and several case
studies are performed on the test system to validate the claims of this research.

▼ It is generally assumed that the hedonic response to an outcome is a joint function of the desirability of the outcome and the likelihood of its occurrence. Losses are almost never pleasurable, but people believe that losses hurt less when they are small and/or expected than when they are large and/or unexpected. Conversely, gains are almost always pleasurable, but are more so when they are large and/or unexpected than when they are small and/or expected. When consumers decide which potential losses to avoid and which potential gains to pursue, their decisions depend on predictions of their hedonic responses to those potential future gains and losses. Thus, an important question is whether affective forecasters are able to accurately predict the extent to which their hedonic responses to an outcome are influenced by the magnitude of the outcome and the probability of its occurrence. This dissertation proposes that affective forecasters overestimate the extent to which their happiness with an outcome depends on its magnitude and its probability of occurrence because of differences in affective intensity between affective forecasters and experiencers. The hedonic experience of an outcome is typically more affectively intense than the simulation of that outcome upon which the affective forecasts for it are based. Intense experiences capture attentional resources required to consider and incorporate outcome specifications into judgment. Consequently, hedonic experiences are less influenced by outcome specifications than are affective forecasts of those experiences. The present research establishes that affective forecasters are more sensitive to the magnitude of an outcome and its probability of occurrence than experiencers. It provides support for the theorized account that the asymmetry in affective intensity evoked by the act of making affective forecasts and having the corresponding hedonic experiences leads to different attention and
sensitivity to these outcome specifications. The difference in
sensitivity to outcome specifications between forecasters and experiencers can lead to under-and overestimation of emotional response: High magnitude and low probability beget overestimation of future emotional response, whereas low magnitude and high probability beget underestimation.

▼ In many dry crop production regions of the world, food-insecure farmers rely on sorghum because of its drought tolerance and ability to yield with low inputs. In Central America and Sub-Saharan Africa, these farmers grow photoperiod sensitive (PS) sorghums, which match natural rainfall patterns with the varieties’ growth and development so that they grow in the rainy season and mature into the dry season. Hybrids, despite their proven yield increases, have not been adopted in these regions. While there are several reasons for the absence of hybrids in these systems, an important factor is the complicated logistics of producing photoperiod-sensitive hybrids and the poor seed production systems in the region. To bypass these limitations, PS hybrids were created from photoperiod-insensitive (PI) parents, allowing the seed to be produced anywhere in the world. The objectives of the study were to 1) assess PS hybrids for heterosis and grain quality and 2) review and assess the potential of this seed production system. Results indicate that grain yield heterosis is present in PS hybrids at high enough levels to be economically viable. In addition, variability for grain quality and for grain yield suggests that further breeding progress can be made. Five hybrids have been chosen for further testing based upon their high yields.

▼ Marked differences in the
sensitivity among fish life-stages and species have been observed for cadmium (Cd) and copper (Cu), two contaminants of particular concern in Canadian surface waters. White sturgeon (Acipenser transmontanus) are highly sensitive to metals such as Cu. Moreover, white sturgeon have also shown significant life-stage-specific differences in
sensitivity to metals. When compared to rainbow trout (Oncorhynchus mykiss), white sturgeon are more sensitive to waterborne acute Cu exposure, whereas the trend in
sensitivity is reversed with Cd exposure. The mechanisms of life-stage- and species-specific differences in
sensitivity among fish species are not well understood, especially for data-poor, non-model species such as white sturgeon. Hence, the overall objective of this study was to characterize the physiological, biochemical and molecular drivers of species-specific differences in the
sensitivity of white sturgeon and rainbow trout to Cd and Cu over three different early life-stages.
During acute waterborne exposure to Cd and Cu, the most important mechanisms of toxicity are the disruption of calcium (Ca) and sodium (Na) homeostasis, respectively. Therefore, I compared the effect of Cd and Cu on uptake and whole-body levels of Ca and Na, respectively, between rainbow trout and white sturgeon across multiple early life-stages. I showed that the greater
sensitivity of white sturgeon to Cu was explained by greater reduction of its sodium Na uptake compared to rainbow trout, when exposed to same waterborne Cu concentration. Similarly, higher
sensitivity of rainbow trout to Cd was explained by significantly higher reduction in Ca uptake relative to white sturgeon. With both Cu and Cd, reduction in whole-body ion uptake resulted in reduction of whole-body levels of Na and Ca, respectively, and the response level was significantly higher in the more sensitive species.
Additionally, I analysed Cd/Cu accumulation, Cd/Cu induced oxidative stress, metallothionein and heat shock protein responses and compared these parameters between rainbow trout and white sturgeon across multiple early life-stages. Species-specific differences in these parameters were evaluated because they are known to be important pathways through which Cd and Cu cause toxicity. In larval and swim-up life-stages, white sturgeon showed greater Cu-induced oxidative damage (lipid hydroperoxide (LPO) induction) than in rainbow trout, which explained the greater
sensitivity of white sturgeon to Cu in early life-stages. Similarly, exposure to Cd showed that rainbow trout, the more sensitive species to Cd, had significantly greater LPO induction at the swim-up and juvenile life-stages as compared to LPO levels in the respective life-stages of white sturgeon. Mechanisms such as antioxidant enzymes, antioxidant molecules, metal accumulation and metallothionein could only partially explain the patterns observed in Cd or Cu induced LPO levels with no consistent response across life-stages. Regardless of the underlying mechanism, LPO seems to be a…

▼ Introduction: Although pulpal necrosis can be associated with orthodontically treated ectopic maxillary canine, the literature is scarce on this topic. Objective: This retrospective study aimed to investigate if ectopic maxillary canines were more predisposed to lack of
sensitivity due to orthodontic treatment. Materials and Methods: The sample was comprised of 20 patients (13 females and 7 males) with a mean age of 21.7 years. Forty maxillary canines were divided into two groups: ectopic (n=26) and non-ectopic (n=14). The post-treatment pulpal assessment included thermal, electrical, and percussion tests. Initial panoramic radiographs were used to assess the axial angulation of the ectopic canines and their linear distance to the occlusal plane. A clinical examination and a questionnaire were used to collect data on 14 background variables capable of influencing on pulp status. Results: There was no influence from axial angulation (p=0.0661) and linear distance (p=0.4840), nevertheless rather from duration of traction (p=0.0437). The mixed-effects logistic regression showed no statistically significant difference between ectopic and non-ectopic canines with regard to pulpal
sensitivity (p=0.0744). From a clinical standpoint, 12 teeth (46.15%) presented with lack of
sensitivity in the ectopic group whereas only two (14.29%) had the same outcome in the control group. Of the 14 background variables, only four would be worth pursuing further research: initial location, presence of gingival recession, bracket slot size, and history of spontaneous pain. Conclusion: Although further studies are still necessary, lack of pulpal
sensitivity can be a side effect when treating ectopic maxillary canines.

▼ Noise sensitivity is a condition characterised by an excessive reaction to harmless levels of sound that would not normally affect typically functioning people. Previous research have found that reactions such as the reduction of attention and concentration as well as the presence of medically unexplained common symptoms such as headaches and fatigue appear in sufferers. The aim of the present study was to investigate whether such a class of sound sensitive individuals are affected by exposure to a potentially unpleasant sound source more than a relatively low sound sensitive group of individuals. Forty adults between 18-54 years of age were exposed to a white noise sound stimulus within a soundproof exposure chamber for 45 minutes. The sound pressure level of the sound varied over the course of the exposure session. The dependent variables of the study were perceived intensity, unpleasantness and effect on concentration, symptoms and cognitive strain. After the exposure session, participants were asked to fill in an online survey that included a 21 item Noise Sensitivity Scale. This was used to group the participants accordingly to a low or high NSS group. The high NSS group compared to the low NSS group had higher ratings for unpleasantness and negative effects on concentration after time point four, at which point the noise stimulus had been introduced. No differences were observed in ratings of Intensity of the noise stimulus between groups. The high NSS group also demonstrated higher ratings for symptoms after the noise stimulus had been introduced. In addition they also demonstrated a lower level of improvement for the cognitive task in comparison to the low NSS group. The findings from this study imply that individuals suffering from hyperacusis can be negatively affected by the presence of annoying sound stimuli. Hyperacusis can mean that sounds can become unpleasant to sufferers as well as potentially affecting their ability to concentrate.
Ljudkänslighet är ett tillstånd som karaktäriseras av en överreaktion på ofarliga ljudnivåer, som normalt inte skulle påverka majoriteten av befolkningen. Tidigare forskning har funnit symptom så som minskad uppmärksamhet och koncentration, samt medicinskt oförklarade symptom som huvudvärk och utmattning förekommer hos drabbade. Syftet med den nuvarande studien var att undersöka hur vida ljudkänsliga personer påverkas mer av en potentiellt obehaglig ljudkälla än en grupp av icke-ljudkänsliga. Fyrtio vuxna mellan 18-54 år exponerades för vitt brus under experimentet. Beroende variabler var upplevd intensitet, obehag, effekt på koncentration, symptom, och kognitiv belastning. Efter experimentet fyllde deltagarna i en online-enkät som inkluderade 21 item Noise Sensitivity Scale. Denna skala användes för att gruppera deltagarna i en hög och en låg NSS-grupp. Jämfört med den låga NSS-gruppen, hade den höga NSS-gruppen högre skattningar av obehag och negativa effekter på koncentrationen efter tidpunkt fyra, då ljud stimulit introducerades.

▼ A spectrally integrated response method is proposed for analyzing transmission data from nanohole array sensors. This method increases the
sensitivity by reducing noise and taking more information from the spectrum for bulk and surface sensing. Results from both real experiments and idealized simulations are presented. Comparison with two other methods- peak transmission wavelength shift and a normalized difference integrated response method are shown. This method shows improved sensing performance which can be exploited in future.
Further improvement in sensing using nanohole arrays is explored by improving the instrumentation of the sensor system. Design parameters of the nanohole arrays for transmission at two different operating wavelengths were examined by using finite difference time domain simulations. Focused ion beam milling was used to fabricate chosen arrays. A microfluidic chip with the embedded nanohole array sensor was used to introduce different solutions for bulk chemical sensing. Intensity measurements were taken with a high speed CMOS camera. Sensing results using this system with possible improvements shows promise for future sensing applications.

▼ Parental anxiety is a well-known factor that contributes to the development of anxiety in children. However, little is known about how specific parental factors influence the development and trajectory of childhood anxiety. There is also a paucity of research on separation anxiety disorder specifically. Complicating matters, children who suffer from clinically significant separation anxiety tend to be younger and thus it is harder to obtain accurate information from this age group. The purpose of the present study was to determine the mechanism through which parental factors such as somatization, anxiety sensitivity, and separation anxious behaviors might influence the development of anxiety in young children (specifically separation anxiety). As a result, 50 children and their mothers completed measures asking about demographic variables, internalizing problems, anxiety sensitivity, and somatization. The results showed that only parental separation anxious behaviors uniquely influenced separation anxious behaviors in children. Results and implications of these findings may be used to direct further examination of influential parental factors and inform treatment by targeting anxious parental behaviors.

▼ Introduction: While insulin resistance and obesity coexist, some obese individuals remain insulin-sensitive. We examined phenotypic and metabolic factors associated with insulin
sensitivity in both muscle and liver in obese individuals. Methods: Sixty-four non-diabetic obese adults (29 males) underwent hyperinsulinaemic (15 and 80 mU/m2/min)-euglycaemic clamps with deuterated glucose. Top tertile subjects for glucose infusion rate during the high-dose insulin clamp (GIRHI) were assigned Musclesen and those in the lower two tertiles were assigned Muscleres. Secondarily, top tertile subjects for endogenous glucose production (EGP) suppression during the low-dose insulin clamp were deemed Liversen and the remainder Liverres. Clinical and laboratory parameters, muscle sympathetic nervous activity (MSNA) and visceral, subcutaneous, liver and pancreatic fat were compared.Results: Musclesen and Muscleres had similar body mass index and total fat (P ≥ 0.12), but Musclesen had lower HbA1c (P < 0.001) and systolic (P = 0.01) and diastolic (P = 0.03) blood pressure (BP). Despite similar subcutaneous fat (P = 0.83), Musclesen had lower visceral (P < 0.001) and liver (P < 0.001) fat. Liversen had lower visceral (P < 0.01) and liver (P < 0.01) fat and CRP (P=0.02) than Liverres. When subjects were grouped by both GIRHI and EGP suppression, insulin
sensitivity at either muscle or liver conferred apparent protection from the adverse metabolic features that characterized subjects insulin-resistant at both sites. HDL-cholesterol, 1-hour glucose, systolic BP and triglycerides explained 54% of the variance in muscle insulin
sensitivity. In men (but not women), MSNA burst frequency correlated inversely with liver insulin
sensitivity (r = -0.53, P = 0.02) and positively with the C-reactive protein (CRP) and fibroblast growth factor (FGF)-19 (r = 0.57, P = 0.006 and r = -0.47, P = 0.03, respectively). Conclusions: Obese subjects who were insulin-sensitive at muscle and/or liver exhibited favourable metabolic features, including lower BP, liver and visceral adiposity. Basal sympathetic nerve activity related to liver insulin
sensitivity in men, but not in women. MSNA associated with the circulating hepatokines CRP and FGF-19, suggesting a potential hepato-endocrine-autonomic axis. This study identifies factors associated with, and possibly contributing to, insulin
sensitivity in obesity.

▼ The hydrology of high-elevation, mountainous regions is poorly represented in Earth Systems Models (ESMs). In addition to regulating downstream water delivery, these ecosystems play an important role in the storage and land-atmosphere exchange of water. Water balances are sensitive to the amount of water stored in the snowpack (snow water equivalent, SWE), as much of Colorado’s water supply is derived from snowmelt. In an effort to resolve this hydrologic gap in ESMs, this study seeks to better understand how uncertainty in both model parameters and forcing affect simulated snow processes. To better understand parameter uncertainty and asses model performance, this study conducts a
sensitivity analysis, using active subspaces, on model inputs (meteorological forcing and static parameters) for both evergreen needleleaf and bare ground land cover types. Observations from an AmeriFlux tower at the Niwot Ridge research site are used to force an integrated single-column hydrologic model, ParFlow-CLM. This study found that trees can mute the effects of sublimation causing the evergreen needleleaf model to be sensitive primarily to hydrologic forcing; humidity in the winter, radiation and air temperature in the summer months. However, bare ground simulations were most sensitive to snow parameters along with radiation as these are unblocked by canopy. The bare ground model is most sensitive to overall changes to the linear combination of input parameters, which means radiation observations and snow parameterizations are of great importance for obtaining accurate hydrologic model results. Humidity measurements are also important, but the change in SWE of the evergreen needleleaf simulations was less than that of the bare ground simulations.

▼ Based on the integrated sensitivity method, we introduce the concept of controlled sensitivity, which enables the sensitivity of a geophysical survey to be focused on a specific target area of sea bottom formation. In particular, we find the optimal parameters of the data weighing, which make it possible to increase the sensitivity of the survey within a specific area, where a potential geological target (e.g., a hydrocarbon reservoir) may be located. We demonstrate this approach with a numerical study of the sensitivity of the marine controlled-source electromagnetic (MCSEM) surveys, developing a numerical method and computer codes for constructing one-dimensional and twodimensional controlled sensitivity for given a priori sensitivity models. This method represents an important technique to increase the resolution of MCSEM data with respect to a specific target area.

▼ When solving an optimization problem, the extreme value of the performance metric of interest is calculated by tuning the values of the design variables. Some optimization problems involve shape change as one of the design variables. Change in shape leads to change in the boundary locations. This leads to a change in the domain definition and the boundary conditions. We consider a 1-D structural element, an elastic bar, for this study. Subsequently, we demonstrate a method for calculating the
sensitivity of solution (e.g. displacement at a point) to change in the shape (length for 1-D case) of the elastic bar. These sensitivities, known as shape sensitivities, are critical for design optimization problems. We make use of continuum analytical shape
sensitivity analysis to derive three variational formulations to compute these shape sensitivities. The accuracy and convergence of solutions is verified using a finite element analysis code. In future, the approach can be extended to multi-dimensional structural and fluid domain problems.

▼ This thesis is to derive the customer load composition and the distribution feeder loss by applying the outage management system (OMS). The distribution system network has been obtained by retrieving the component information from OMS database. The topology process and equipment reduction have also been executed to identify the network configuration and to prepare the input data for load flow analysis. With the monthly energy consumption of customers served by each transformer, which has been retrieved from the customer information system (CIS), the hourly loading of each distribution transformer is then derived. By performing the three phase load flow analysis for different types of distribution feeders, the power loss of distribution feeders has been obtained. To solve the effect of temperature change to the power consumption of distribution feeders, the temperature sensitivities of power consumption of each customer class are solved by multiple regression analysis with 95% confidential level. Based on the temperature
sensitivity of the load component and the power loss, the increase of load demand and the power loss due to temperature rise can be estimated. Three practical distribution feeders in Taipei City District of Taipower are selected to demonstrate the impact of temperature change. To the feeder power consumption, it is found that the change of load demand for both residential and commercial customers is more significant as compared to the industrial customers. By applying the OMS for distribution system loss analysis, the feeder power loss can be evaluated according to the hourly loading, which can provide an effective tool to support the assessment of distribution system operation efficiency.

▼ Sensitivity analysis is essential for the hydrologic models to help gain insight into models behavior, and assess the model structure and conceptualization. Parameter estimation in the distributed hydrologic models is difficult due to the high-dimensional parameter spaces.
Sensitivity analysis identified the influential and non-influential parameters in the modeling process, thus it will benefit the calibration process.
This study identified, applied and evaluated two
sensitivity analysis methods for the APEX model. The screening methods, the Morris method, and LH-OAT method, were implemented in the experimental site in North Carolina for modeling runoff, sediment loss, TP and DP losses. At the beginning of the application, the run number evaluation was conducted for the Morris method. The result suggested that 2760 runs were sufficient for 45 input parameters to get reliable
sensitivity result.
Sensitivity result for the five management scenarios in the study site indicated that the Morris method and LH-OAT method provided similar results on the
sensitivity of the input parameters, except the difference on the importance of PARM2, PARM8, PARM12, PARM15, PARM20, PARM49, PARM76, PARM81, PARM84, and PARM85. The results for the five management scenarios indicated the very influential parameters were consistent in most cases, such as PARM23, PARM34, and PARM84. The sensitive parameters had good overlaps between different scenarios. In addition, little variation was observed in the importance of the sensitive parameters in the different scenarios, such as PARM26.
The optimization process with the most influential parameters from
sensitivity analysis showed great improvement on the APEX modeling performance in all scenarios by the objective functions, PI1, NSE, and GLUE.

▼ The increased public outcry has brought public attention to the killings and excessive force used by police officers in the United States on unarmed African American males and criticism of the lack of police implicit bias training within the police services and the criminal justice system. The police bias involves the policing of immigrants, homelessness, Muslims, the LBGTQ community, and the non-English speaking Americans. The Michigan Commission on Law Enforcement Standards (MCOLES) is the governing agent in Michigan for licensing and training of police cadets and police officers. This qualitative study is a content analysis of the MCOLES Cultural Awareness and Diversity Curriculum to see how the MCOLES standards correspond to scientific evidence on reducing implicit bias behavior in officers. The findings suggest that the MCOLES curriculum does not meet the scientific standards on implicit bias training. The training will require significant enhancements that will include America's bias police history, police biases processes, sensitivity training, strategies to promote long term reduction of bias police behavior, and assessment to evaluate police racial attitudes.

▼ The present study tested predictions derived from the Dual Representation Theory (DRT) of memory intrusions in Posttraumatic Stress Disorder (PTSD). It was hypothesized that engagement in a visuospatial task after watching a trauma film would result in a reduction in intrusions and better intentional memory recall relative to a verbal and non-task control conditions, and that engagement in a verbal task would have opposite effects. The present study further examined the effects of visuospatial and verbal tasks on trauma-related memory when these tasks were matched in difficulty and engagement levels. In Study 1, participants in visuospatial, verbal, and control conditions were presented with a trauma film. Then they were asked to record intrusions over a one-week period and their intentional memory recall was assessed one week later. Contrary to predictions, the three conditions failed to differ significantly on intrusions or intentional memory recall. Study 2 attempted to replicate more directly prior findings by using the visuospatial task ¡®Tetris¡¯ that has been used successfully in prior studies. In contrast to hypothesis and previous research, there were no between-condition differences in intrusions. Exploratory analyses in Study 1 and Study 2 did reveal significant positive relations between anxiety
sensitivity and PTSD symptoms, even after controlling for depression and trait anxiety. The findings implicating anxiety
sensitivity in PTSD are discussed in the context of treatment and prevention efforts. Discussion focuses on the implications of the inconsistent experimental findings for an evaluation of the validity of the DRT.

▼ This research presents new physics-based methods to estimate predictive uncertainty stemming from uncertainty in the material opacities in radiative transfer computations of key quantities of interest (QOIs). New methods are needed because it is infeasible to apply standard uncertainty-propagation techniques to the O(105) uncertain opacities in a realistic simulation. The new approach toward uncertainty quantification applies the uncertainty analysis to the physical parameters in the underlying model used to calculate the opacities. This set of uncertain parameters is much smaller (O(102)) than the number of opacities. To further reduce the dimension of the set of parameters to be rigorously explored, we use additional screening applied at two different levels of the calculational hierarchy: first, physics-based screening eliminates the physical parameters that are unimportant from underlying physics models a priori; then,
sensitivity analysis in simplified versions of the complex problem of interest screens out parameters that are not important to the QOIs. We employ a Bayesian Multivariate Adaptive Regression Spline (BMARS) emulator for this
sensitivity analysis. The high dimension of the input space and large number of samples test the efficacy of these methods on larger problems. Ultimately, we want to perform uncertainty quantification on the large, complex problem with the reduced set of parameters. Results of this research demonstrate that the QOIs for target problems agree at for different parameter screening criteria and varying sample sizes. Since the QOIs agree, we have gained confidence in our results using the multiple screening criteria and sample sizes.

▼ Trauma exposure is consistently associated with men’s perpetration of intimate partner violence (IPV), potentially due to trauma-related biased perception of threat. In this area of research, threat is typically defined in terms of physical danger or harm. To date, it is not well known if threat functionally motivates initiation of aggression or if the nature of threat extends beyond stimuli signaling physical danger/harm. However, theory and limited research suggest that threats of rejection/abandonment and threats of social dominance may reflect distinct functional precipitants of aggression perpetration among trauma-exposed men. This study was designed to assess men’s aggressive responses in the context of their wives’ rejection/abandonment and social dominance threats in order to better understand the circumstances in which aggression is used among men varying in degree of trauma exposure. Among 64 community couples selected for elevated symptoms of PTSD in either partner, husbands’ aggressive behaviors and their wives’ threats of rejection/abandonment and social dominance were objectively observed during couple conflict interactions. The severity of wives’ rejection/abandonment threats predicted the severity of husbands’ aggression perpetration among husbands with high ( = .71, t = 3.68, p < .001), but not low ( = .03, t = .18, p = .854), levels of trauma exposure. Likewise, the severity of wives’ social dominance threats predicted the severity of husbands’ aggression perpetration among husbands with high ( = .67, t = 5.34, p < .001), but not low ( = .08, t = .54, p = .590), levels of trauma exposure. Thus, men with relatively high trauma exposure may respond aggressively to women’s threats of rejection/abandonment and social dominance. These findings are consistent with research suggesting that traumatized men’s misperceptions of threat may motivate their aggression, and indicate that aggression may also be used in the context of accurately detected threat. Findings also suggest that men may respond aggressively to an array of objectively threatening behaviors, including those that reflect rejection/abandonment and social dominance.

▼ The ability of the body to manage blood sugar is referred to as insulin sensitivity. Reduced insulin sensitivity is both a risk factor and is involved in the pathogenesis of type-2 diabetes. Cardiorespiratory fitness (CRF) is an established predictor of insulin sensitivity. Whether this association persists following control for exercise is not known. The primary objective of this study was to determine the independent associations between changes in exercise, CRF and insulin sensitivity. The influence of changes in body weight and waist circumference (WC) on these associations was examined in secondary analyses.
Participants were 140 middle-aged, inactive, abdominally obese adults that participated in a 24-week exercise program. Exercise was performed 5 times per week for the duration of the program and was measured as Calories of energy expended, herein referred to as exercise energy expenditure (exercise EE). CRF was measured using a treadmill test to exhaustion. Body weight was measured on a Detecto scale and WC was measured at the level of the hip bone. Physical activity performed outside of the exercise sessions was measured using portable activity monitors known as accelerometers. Caloric intake was monitored using daily diet records. Following oral consumption of a 75-gram glucose drink, 2-hour insulin area under the curve was calculated as a measure of insulin sensitivity.
Change in insulin sensitivity was associated with exercise EE, change in CRF, change in body weight and change in WC. Exercise EE was associated with change in insulin sensitivity after we adjusted for change in CRF, whereas change in CRF was not associated with change in insulin sensitivity after we adjusted for exercise EE. After further adjustment for changes in body weight and WC, neither exercise EE nor change in CRF were associated with change in insulin sensitivity. Changes in body weight and WC were associated with change in insulin sensitivity after adjustment for exercise EE and change in CRF.
The principle finding of this study was that the link between CRF and insulin sensitivity is largely explained by variations in exercise. Further, a reduction in obesity is one of the ways in which exercise improves insulin sensitivity.

▼ Introduction: Accommodation and vergence, in unison, help in maintaining a clear and single binocular vision, a linchpin for normal vision development. Under natural viewing conditions, accommodation and vergence systems mutually interact with each other through a unique cross-link mechanism. Based on the empirical data from visually normal adults, several control theory models were proposed to predict the behavior of accommodation and vergence. Progressive myopic children, however, exhibit a transient but consistent abnormal accommodative behavior which is not predicted by the currently accepted models. Progressive myopes exhibit high accommodative adaptation, elevated AC output coupled with high accommodative lags. Several predictions, both sensory and motor origin, have been proposed to explain this behavior however they failed to predict this behavior completely. Furthermore, empirical conclusions on the impact of myopia over accommodation and blur sensitivity were mostly based on data obtained from adult population. Accordingly, this dissertation examined the sensory and motor mechanism of accommodation in young children with and without progressive myopia. Data from children were also compared to adults.
Methods: 12 children (8-13 years), 6 myopic and 6 non-myopic, and 6 naïve adults (25-33 years) were recruited for the purpose of this dissertation. Varying demands of accommodation were stimulated using a Badal optical system and recorded using custom-built dynamic photorefraction system (DPRS). Theoretical and empirical designs were developed to identify the ideal sampling rate necessary to measure a dynamic accommodative response. First and second order main sequence relationship and strength of the cross-link (CA) response was tested in the first experiment. In the second experiment, blur discrimination thresholds were tested psychophysically using simulated blur targets at two different stimulus demands. Furthermore, objective DOF and sensitivity of accommodative system to blur were examined using known demands of lens defocus and compared across different subject groups.
Results: The new custom built high speed photorefractor (DPRS) was found to be superior in measuring dynamic accommodation compared to the commercially available Power Refractor (p <0.001). The current dissertation makes four major contributions to the field of accommodation and myopia: first, a motor deficit such as a sluggish or rigid plant cannot explain the abnormal behavior of accommodation in myopes. This was established based on the findings of a similar first and second order main sequence relationship between myopes and non-myopes (p > 0.05). Also, CA/C measures were not found to be attenuated as would be expected with a rigid plant. Novel simulations with reduced blur sensitivity coupled with a motor recalibration of AC gain did predict the myopic behavior. Second, atypical response patterns of accommodation such as the dynamic overshoots and double step responses were reported to exist with blur-driven accommodation. These…

▼ Solar energy has seen ever-increasing implementation as a power source throughout the world since its introduction into the energy production market. Meteorological parameters including temperature, wind speed and albedo can have significant impacts on the amount of power that is produced at a utility-scale solar farm. This study sought to review the
sensitivity of solar energy production to these varying weather parameters. The modeled
sensitivity was tested by running simulations using modified weather data and comparing the power output to a baseline simulation. Results show that temperature has a significant effect in the efficiency of the solar panels, and by extension, the power produced. Wind speed plays a significant role in heat dissipation, while modifying albedo results in a change in the power produced as well, albeit to a lesser extent.

▼ The general field of the thesis is the
sensitivity analysis of black-box functions.
Sensitivity analysis studies how the variation of the output can be apportioned to the variation of input sources. It is an important tool in the construction, analysis, and optimization of computer experiments. The total interaction index is presented, which can be used for the screening of interactions. Several variance-based estimation methods are suggested. Their properties are analyzed theoretically as well as on simulations. A further chapter concerns the
sensitivity analysis for models that can take functions as input variables and return a scalar value as output. A very economical sequential approach is presented, which not only discovers the
sensitivity of those functional variables as a whole but identifies relevant regions in the functional domain. As a third concept, support index functions, functions of
sensitivity indices over the input distribution
support, are suggested. Finally, all three methods are successfully applied in the
sensitivity analysis of sheet metal forming models.
