▼ When mixing and mastering modern music, many engineers strive for making the end product to be perceived as loud as possible without sacrificing audio quality. Achieving this will often involve reducing the dynamic range of a track through peak limiting. By reducing the level of the loudest transients, the additional headroom can be used to raise the overall level of the track. This method of maximizing loudness through transient suppression has, arguably, made it more relevant to understand the human perception of transients. By further understanding the psychoacoustical factors that plays a role in how transient loudness is perceived, engineers could hopefully achieve greater audio quality while maximizing loudness, if desirable. This paper will focus on how the signal duration of a transient will affect its perceived loudness and potentially compensate for level changes within transients. The fact that sound signals of longer duration are perceived as louder than signals of shorter duration has been proven several times in prior research. This effect is tested again, in this research, by letting participants match the loudness of several short pink noise bursts of varying durations. The noise bursts are designed to mimic the envelope of a typical snare drum transient, which makes the stimuli differ from stimuli tested in prior experiments testing the same effect. Based on the result from this experiment, each transient is normalized to be perceived as equally loud. Then, a stationary component is added to every transient to make each stimuli mimic a full typical snare drum. In a second experiment, each stimuli is then compared against each other in an ABX test to see if listeners can perceive the differences. The results from the first experiment showed that transients were perceived to be approximately 0.3 dB louder per 5 ms increase in duration. In the second experiment, listeners failed to hear the differences between stimuli when transient duration differed less than 5 ms. For differences in duration longer than this, listeners correctly identified the differences.

▼ The BHA gas field plays a significant role in Oman's gas production. However, production forecasts and reserves estimation in this gas condensate field have shown considerable uncertainty due to the formation complexity and the relatively low permeability (1-5 md). Mismatches between the observed reservoir performance and deterministic performance predictions have resulted in continuous revision of the booked reserves for this field. To address these reserves revisions, we deployed modern time-rate analysis and time-pressure-rate analysis techniques to improve the analysis and interpretation of the reservoir performance data, and thus better constrain the estimated ultimate recovery (EUR) results for the BHA field. Microsoft® Excel® is used to perform "time-rate" or "decline curve" analysis (DCA) on a selected group of fourteen wells. These wells were chosen based on the continuity of the production data (some wells do not have continuously measured pressures). We follow the industry-standard practice for wells in unconventional reservoirs, where the EUR is estimated at 30 years from the forecasted production trend. Specifically, we estimate reserves using both the Modified Hyperbolic (MH) and Power Law Exponential (PLE) methods. In addition to "time-rate" analysis, we also perform "time-rate-pressure" analysis or "rate transient analysis" (RTA) on these same fourteen well cases using the commercial software package Topaze (Kappa Engineering). In the RTA workflow, we first utilize the diagnostic plots to estimate model parameters and then perform a simulation history match using the anazlytical solution for a vertical well with a finite- or infinite-conductivity vertical fracture. Using the history-matched reservoir model, we then generate a forecast of at least 30 years and we use the cumulative production at 30 years as a proxy for EUR for comparison with DCA methods. We tabulate the 30-year EUR values from DCA and RTA, as well as the model parameters used to obtain these forecasts. We provide simplified correlations of EUR results and model parameters for the DCA and estimates of reservoir properties obtained from RTA. The overall goal of this work is to demonstrate the applicability of these methods to improve our confidence in the estimated reserves for the BHA field.

▼ The common development plan for operators in the Williston Basin has been to initially drill and complete one well in order to hold a 1280 acre spacing unit. Once acreage is secure across the asset, operators return to each spacing unit and drill infill wells. By the time infill wells are drilled, reservoir depletion from the original (parent) well can be observed within the spacing unit. Reservoir depletion increases the likelihood of existing wells experiencing inter- communication when infill wells are hydraulically fractured. Such inter-well communication, or frac-hits, often have detrimental effects on existing wells. As such, understanding the effect of well timing and spacing on overall spacing unit performance is of critical importance when determining an appropriate development plan. Rate transient analysis (RTA) is an effective way to quantify the impact of offset frac hits, providing changes in reservoir properties such as stimulated rock volume (SRV) and well productivity. This study used pseudo normalized pressure versus material balance square root of time plots in order to determine the impact of offset frac hits on existing wells. The slope of the superposition time plot is inversely proportional to A_c â(k ) , which offers a good metric for early time well productivity and completion effectiveness. Superposition time plots were created, and a production lookback was performed on 71 operated wells in northern Divide County, North Dakota. Changes observed in reservoir properties and production performance were used to determine appropriate well spacing and infill timing. In addition, this study conducted a look back economic evaluation for 71 wells and 15 spacing units, using current commodity pricing, to assess the investment efficiencies of each project. Results from rate transient analysis, production analysis, and the economic evolution indicate that 5 â 6 wells is the optimal wells spacing per 1280 acre spacing unit within the study area.

▼ This dissertation focuses on the catchment-scale evaluation of groundwater age as a function of space and time in the 270 km² Middle Wairarapa catchment. The simulation of the mean age and point distribution of ages, contributing to a regional age estimate, is a novel demonstration of the recently developed groundwater software, Cornaton (2012). The Wairarapa is in the southern North Island of New Zealand and is a dynamic water catchment exhibiting complex interactions between its rivers and shallow aquifers. Groundwater has been widely utilized since the 1980s for agriculture, horticulture and drinking water; increasing land use development (i.e. irrigation and nutrient application) requires effective regional management of both the quantity and quality of water resources. Groundwater age provides insights into groundwater flow and transport processes and thus enables better management of groundwater resources. Subsurface water age information enables the interpretation of recharge influence, zones of sensitivity for sustainable abstraction, as well as contamination risk from land-use intensification to drinking water supplies. It is accepted that groundwater is composed of a mixture of water with different ages, however, until very recently mean age has been the primary indicator for groundwater age assessment. Mean age alone can misrepresent the potential for contamination from young water; for example, a groundwater sample with an old mean age may still contain a significant fraction of young water; therefore, a fuller understanding of the age distribution in both time and space is important for groundwater management. The ability to simulate the full distribution of groundwater age within transient numerical groundwater models has only been very recently enabled, through implementation of the time-marching Laplace transform Galerkin technique (TMLTGT), and is demonstrated in this dissertation. A transient finite-element groundwater flow model originally developed by Greater Wellington Regional Council was converted to simulate transport of the age tracer tritium and groundwater age using the Ground Water (GW) software. Observed tritium concentrations were utilized in the calibration using the Monte Carlo and Gauss-Marquardt-Levenberg methods. Following the calibration of the transport model the GW software was then used to derive pumping well capture zones and directly simulate age throughout the Middle Wairarapa Valley catchment. The advective dispersive equation and the TMLTGT were used for transient mean-age and transient simulations of the full distribution of groundwater age. The results are presented as maps and graphs of both mean age and age distributions throughout the Middle Valley, covering a 15 year simulation period. The mean-age simulations indicated the groundwater age in the valley was strongly influenced by seasonal changes and extreme climatic events. Significant variations existed, from high rainfall recharge percolating young water throughout the domain, to dry extended droughts limiting… Advisors/Committee Members: Jackson, Bethanna, Daughney, Chris.

ENGLISH ABSTRACT: The purpose of this project is to develop a numerical transient simulation model of the CO2 refrigeration cycle containing a capillary tube as expansion device. A design procedure for CO2 refrigerators is also developed; which makes use of a steady-state capillary tube model for acquiring the initial design of the capillary tube, and uses the transient simulation program to determine the low pressure side internal volume and validate the complete design of the refrigerator. Using this design procedure a CO2 refrigerator was designed, built and then tested to validate the simulation model developed. The project was conducted at the Department of Mechanical and Mechatronic Engineering at the University of Stellenbosch. A literature review on the history of refrigeration, the vapour-compression refrigeration cycle, the transcritical CO2 refrigeration cycle, refrigerant properties, CO2 properties, and a comparison of refrigerant performance was done as background to the use of CO2 as refrigerant. Furthermore, literature review of an alternative expansion device, the vortex tube, was included, but found not practical for implementing with CO2 which behaves more like a real gas and not an ideal gas. Lastly, theory on the development of the one-dimensional CFD finite volume method in terms of a general variable is shown. This provides background to the development of discretised conservation equations for the simulation model. The transient model developed is capable of predicting transient operation from stand-still starting conditions through to steady-state conditions. The model makes use of well-known pipe friction and heat transfer correlations. Furthermore, it makes use of the real gas equation of state for CO2 from Span and Wagner (1996). Moreover, the model determines whether the flow is single - or two-phase and then calculates the appropriate properties. Lastly, it has the whole refrigerant circuit, from compressor outlet back to compressor inlet, as the simulation domain. The simulation results for the pressure and temperature distributions show the transient behaviour at start-up. The transient and steady-state results also agree fairly well with the experimental results. The steady-state pressure graphs are as expected and the constant evaporation temperature is a confirmation that the model approximates real life operation quite well. In conclusion, the results show that the simulation model is a useful tool for designing and understanding capillary tube CO2 refrigeration cycles. Future work involves developing a nonadiabatic compressor model and models for alternative expansion devices to be included in the current refrigerator simulation model.

▼ With the evolution of modern Complementary Metal-Oxide-Semiconductor (CMOS) technology, transistor feature size has been scaled down to nanometers. The scaling has resulted in tremendous advantages to the integrated circuits (ICs), such as higher speed, smaller circuit size, and lower operating voltage. However, it also creates some reliability concerns. In particular, small device dimensions and low operating voltages have caused nanoscale ICs to become highly sensitive to operational disturbances, such as signal coupling, supply and substrate noise, and single event effects (SEEs) caused by ionizing particles, like cosmic neutrons and alpha particles. SEEs found in ICs can introduce transient pulses in circuit nodes or data upsets in storage cells. In well-designed ICs, SEEs appear to be the most troublesome in a space environment or at high altitudes in terrestrial environment. Techniques from the manufacturing process level up to the system design level have been developed to mitigate radiation effects. Among them, silicon-on-insulator (SOI) technologies have proven to be an effective approach to reduce single-event effects in ICs. So far, 28nm ultra-thin body and buried oxide (UTBB) Fully Depleted SOI (FDSOI) by STMicroelectronics is one of the most advanced SOI technologies in commercial applications. Its resilience to radiation effects has not been fully explored and it is of prevalent interest in the radiation effects community. Therefore, two test chips, namely ST1 and AR0, were designed and tested to study SEEs in logic circuits fabricated with this technology. The ST1 test chip was designed to evaluate SET pulse widths in logic gates. Three kinds of the on-chip pulse-width measurement detectors, namely the Vernier detector, the Pulse Capture detector and the Pulse Filter detector, were implemented in the ST1 chip. Moreover, a Circuit for Radiation Effects Self-Test (CREST) chain with combinational logic was designed to study both SET and SEU effects. The ST1 chip was tested using a heavy ion irradiation beam source in Radiation Effects Facility (RADEF), Finland. The experiment results showed that the cross-section of the 28nm UTBB-FDSOI technology is two orders lower than its bulk competitors. Laser tests were also applied to this chip to research the pulse distortion effects and the relationship between SET, SEU and the clock frequency. Total Ionizing Dose experiments were carried out at the University of Saskatchewan and European Space Agency with Co-60 gammacell radiation sources. The test results showed the devices implemented in the 28nm UTBB-FDSOI technology can maintain its functionality up to 1 Mrad(Si). In the AR0 chip, we designed five ARM Cortex-M0 cores with different logic protection levels to investigate the performance of approximate logic protecting methods. There are three custom-designed SRAM blocks in the test chip, which can also be used to measure the SEU rate. From the simulation result, we concluded that the approximate logic methodology can protect the digital logic efficiently.… Advisors/Committee Members: Chen, Li, Ko, Seok-Bum, Kasap, Safa, Wahid, Khan, Vassileva, Julita.

▼ Advances in wide area measurement systems have transformed power system operation from simple visualization, state estimation, and post-mortem analysis tools to real-time protection and control at the systems level. Transient disturbances (such as lightning strikes) exist only for a fraction of a second but create transient stability issues and often trigger cascading type failures. The most common practice to prevent instabilities is with local generator out-of-step protection. Unfortunately, out-of-step protection operation of generators may not be fast enough, and an instability may take down nearby generators and the rest of the system by the time the local generator relay operates. Hence, it is important to assess power system stability over transmission lines as soon as the transient instability is detected instead of relying on purely localized out-of-step protection in generators. This thesis proposes a synchrophasor-based out-of-step prediction methodology at the transmission line level using wide area measurements from optimal phasor measurement unit (PMU) locations in the interconnected system. Voltage and current measurements from wide area measurement systems (WAMS) are utilized to find the swing angles. The proposed scheme was used to predict the first swing out-of-step condition in a Western Systems Coordinating Council (WSCC) 9 bus power system. A coherency analysis was first performed in this multi-machine system to determine the two coherent groups of generators. The coherent generator groups were then represented with a two-machine equivalent system, and the synchrophasor-based out-of-step prediction algorithm then applied to the reduced equivalent system. The coherency among the group of generators was determined within 100 ms for the contingency scenarios tested. The proposed technique is able to predict the instability 141.66 to 408.33 ms before the system actually reaches out-of-step conditions. The power swing trajectory is either a steady-state trajectory, monotonically increasing type (when the system becomes unstable), or oscillatory type (under stable conditions). Un- der large disturbance conditions, the swing could also become non-stationary. The mean and variance of the signal is not constant when it is monotonically increasing or non-stationary. An autoregressive integrated (ARI) approach was developed in this thesis, with differentiation of two successive samples done to make the mean and variance constant and facilitate time series prediction of the swing curve. Electromagnetic transient simulations with a real-time digital simulator (RTDS) were used to test the accuracy of the proposed algorithm with respect to predicting transient in- stability conditions. The studies show that the proposed method is computationally efficient and accurate for larger power systems. The proposed technique was also compared with a conventional two blinder technique and swing center voltage method. The proposed method was also implemented with actual PMU measurements from a relay (General Electric… Advisors/Committee Members: Gokaraju, Rama, Chowdhury, Nurul, Wahid, Khan, Cree, Duncan.

▼ In many engineering applications, thermal shock is an issue that requires serious attention. When a material experiences a large change in temperature, its mechanical properties can change dramatically. Furthermore, any sudden changes in temperature can adversely deform and stress the material such that failure occurs. It is important to be able to monitor sudden changes in temperature in order to avoid these failures. Often times in studies of thermal shock, the boundary condition at the surface is not known, and the direct solution is no longer useful. However, the temperature must still be calculated. These types of situations require an inverse method. As its name implies, it is the opposite of the direct method. Instead, the thermal response at some remote location is used to solve for the boundary condition at the surface. In this thesis, the inverse heat conduction problem was analyzed where the thermal conductivity was assumed to depend on temperature. The inverse method was performed on a semi-infinite slab with an asymptotic exponential thermal surface loading with both increasing and decreasing conductivity. A generalized direct solution was devised and analyzed. The temperature was calculated symbolically in terms of unknown coefficients. A thermal response was measured at a remote location, and the data was fit to the unknown coefficients using the least-squares method. A finite element simulation was run as confirmation. The inverse problem showed excellent agreement compared to the finite element model. In addition to solving for surface temperature, the inverse method can also be used to solve for thermophysical properties such as thermal conductivity. The conductivity can be calculated using the inverse problem provided that the coefficients of the conductivity equation are at least on the order of one. The same process was performed for the finite slab; however, due to complications in computation, the software used was unable to perform the inverse method. However, the method is still conceptually valid and could be done with a more targeted approach. Therefore, only the direct problem was analyzed for the finite slab. Using a Taylor series approximation, good agreement was achieved between the analytical and finite element models. After several seconds, this approximation would become very crude, as the analytical model would sharply diverge from the finite element model. It was proven that an integral within the solution can be modeled as a constant several seconds into the transient analysis; this prevented the divergence that was caused by the Taylor series approximation. The agreement between both the semi-infinite and finite slab models and their finite element counterparts improved as the thermal wave reached the point of interest more quickly. Given the versatility of the polynomials used in the cases presented, the method appears well suited for monotonic or mildly-oscillatory thermal scenarios provided the analysis is restricted to the time interval used to… Advisors/Committee Members: Albert Eliot Segall, Thesis Advisor/Co-Advisor, Albert Eliot Segall, Thesis Advisor/Co-Advisor, Corina Stefania Drapaca, Thesis Advisor/Co-Advisor.

▼ Unconventional resources which are generally categorized by their extremely low permeability and high heterogeneity have become increasingly appealing over recent years. The typical development strategy is drilling horizontal wells with tight spacing hydraulic fractures. Such strategy leads to a significant loss of flowing area during fracture interference, thus resulting in a transition flow regime with unit slope identified as pseudo pseudo-steady state flow. Capturing such flow regime is critical in delivering accurate reservoir performance analysis. This thesis discusses a methodology to accurately capture drainage and pressure depletion behavior of horizontal wells with multiple hydraulic fractures. We will use asymptotic solution with separation of variables in order to model the pseudo pseudo-steady state flow regime. A more precise modeling of pressure behavior with analytical asymptotic solution ensures more confident reservoir forecast with low computation time. Traditionally, we utilize two main methods to conduct unconventional reservoir calibration and forecast in order to obtain Estimated Ultimate Recovery (EUR). The first one is an analytical method such as decline curve analysis. It is a simplified empirical method which is time efficient however also ignores vital information such as complex geometries. The second method is by numerical simulation which takes into account of the geometries and heterogeneity, but is also time consuming especially when reservoir models contain millions of grid cells. The Fast Marching Method emerges as a novel approach to calibrate and forecast reservoir performance with significantly reduced calculation time. The validity of this method has been tested in transient phase (infinite acting flow regime) of pressure diffusion. However, considering the vast existence of hydraulic fractured horizontal wells in unconventional reservoirs, adjacent fractures create virtual boundary conditions. Accordingly, the flow regime associated with hydraulic fractured horizontal wells is channel flow. Such flow regime is characterized by pressure front encountering boundary conditions in one direction while remain infinite acting in the perpendicular direction. Therefore we introduce the separation of variables in order to analyze pressure front propagation in these two directions independently. Such method optimizes the calculation of drainage volume in channel flow scenario, thus capable of modeling the signature feature of unconventional reservoirs, pseudo pseudo-steady state flow regime, more accurately. The results from this methodology is compared against the ones from numerical simulation as validation.

▼ A hybrid bearing designed for use in a next generation turbo-pump is evaluated for the performance of initial lift-off, referred to as start-transient. The radial test rig features a high-speed spindle motor capable of 20,000 rpm that drives a 718 Inconel rotor attached via a high-speed coupling. The drive end is supported by ceramic ball bearings, while the hybrid bearing supports the opposite end. A magnetic bearing delivers the applied loading along the mid-span of the rotor. Many parameters, including ramp rate [rpm/s] (drive torque), supply pressure at 15,000 rpm, magnitude of the applied load, and load orientation, are varied to simulate different start-transient scenarios. The data are recorded in .dat files for future evaluation of transient predictions. Analysis of the data includes an evaluation of hydrodynamic and hydrostatic liftoff, an assessment of rub from passing through a lightly damped critical speed, and observation of pneumatic hammer instability. Hydrodynamic lift-off occurs when the hydrodynamic pressure, resulting from the relative motion of two surfaces, overcomes the forces acting on the rotor; no indication of hydrodynamic lift-off is provided. Hydrostatic lift-off results from the external supply pressure (which for this test rig is speed dependent) overcoming the forces acting on the rotor as determined from rotor centerline plots. With 0.263 bar applied unit load in the vertical direction, hydrostatic lift-off occurs at 0 rpm and 2.08 bar supply pressure. With a much higher load of 1.53 bar, hydrostatic lift-off is at 12,337 rpm and 10.7 bar supply pressure. The required supply pressure for hydrostatic lift-off is approximately a linear function of the applied unit load. In a turbopump, hydrostatic lift-off depends on the speed because the supply pressure is proportional to the speed squared. With the load in the horizontal direction, hydrostatic lift-off occurs at lower speeds and pressures. The ramp rate did not affect the required supply pressure for hydrostatic lift-off. A lower supply pressure at 15,000 rpm lowered the required supply pressure for hydrostatic liftoff as well as the natural frequencies creating a rub. The hydrostatic lift-off speed should be minimized to avoid damage to the rotor/bearing surfaces due to contact.

▼ Permeability and porosity are two very important reservoir properties needed to be accurately measured when studying gas and oil reservoirs, which are essential for designing an optimal and efficient development program of an oil and gas field. There are several ways to determine the permeability and porosity, such as laboratory experiments. It is using cores obtained from a reservoir, which is expensive, complicated, labor intensive and time consuming. Another way is well logging, which has difficulties and uncertainties to directly interpret permeability and porosity. Therefore, alternate methodologies for accurate determination of permeability and porosity are desirable. An artificial neural network (ANN) has the potential to build a model that can be used as an effective tool for permeability and porosity prediction. It has the ability to understand a highly non – linear relationship and to perform simulation studies in a rapid manner. Artificial neural networks for this problem were developed based on well test data, which is more accurate and reflects the whole ̶ flow characteristic in porous media as compared to laboratory and well ̶ logging methods. Moreover, comparing it with other simulation models, the artificial neural network model is not restricted by difficulty to update for different systems. In this study, the model is built with data from dual ̶ lateral wells, which are the major methods to achieve higher accumulative production to meet the current high demand of energy consumption. In previous studies (Basbug, 2007), the authors predicted permeability and porosity with only reservoir and fluid properties without specifying the well type in the reservoir. Therefore, their model may not apply to the situation with dual ̶ lateral wells. In this study, the well ̶ configuration parameter and well test data are added into the ANN model, which is more accurate in estimating permeability and porosity as compared to the previous model. An artificial neural network consists of two primary elements: neurons and interconnections. The number and kinds of neurons are determined by training and learning processes that depend on the input and output data. In the development of the ANN model here, a wide range of data sets were collected from the literature. Those data sets were used for training, testing and validating the proposed model. The objective of this study is to generate two ANN models. The forward model was built to generate the pressure transient data and estimate whether the surface flow rate is reasonable for a specified reservoir. The inverse ANN model was developed to determine permeability and porosity of a specified reservoir with dual ̶ lateral wells. And two Graphic User Interfaces were developed for the forward and inverse ANN models. In the end, the inverse neural network was applied to heterogeneous and anisotropic system to see how well it can perform. For homogeneous and anisotropic system, the forward neural network has approx 86% probability to obtain the result within 0-5% error.

▼ Transient storage models are used to simulate solute transport in streams. The processes characterized and the parameters interpreted from these models are important to our understanding of biogeochemical cycling. Single storage zone (1-SZ) models lump portions of the stream with different biogeochemical and hydrodynamic characteristics into one zone. Recent progress has been made to develop transient storage zone models with two-storage zones (2-SZ) to discriminate between surface and subsurface (hyporheic) exchange. Surface transient storage (STS) is the non-advective portion of channels that surround and sometimes divide the main channel, while hyporheic transient storage (HTS) is the wetted subsurface area adjacent to the stream. These storage zones are subject to different physical and biogeochemical conditions. Thus, to advance biogeochemical models, we want to separate the effects of these storage zones. In models with multiple transient storage zones, each storage zone can exchange with the stream, another storage zone, or both. In a competing model structure both zones are connected to the stream at the same location and the stream interacts with the STS and HTS separately; whereas in a nested model structure the STS interacts directly with the stream and the HTS interacts only with the STS. Residence time metrics used to compare single transient storage models were adapted for use with the competing and nested 2-SZ models and are model-structure based. We investigated the transient storage characteristics of a 460-m reach of Laurel Run, a first-order stream in central Pennsylvania, using a 1-SZ, nested 2-SZ, and competing 2-SZ model configurations. This study modeled the solute breakthrough curves from three salt tracer experiments ranging from high to low flows and compared the results. Results show that both the competing and nested 2-SZ models iv may accurately simulate the BTCs obtained in the STS and main channel. The calibrated model parameters differ for the three model structures, and therefore so does the interpretation of associated transient storage metrics. The new 2-SZ metrics were applied to this data and the results suggest that the interpretation of transient storage processes and its relationship with biogeochemical cycling processes is dependent on model structure.

This research studies the effects of a postulated Main Steam Line Break accident in a nuclear plant on the transient loading of steam generator tubes. The problem involves complex transient two-phase flow dynamics and fluid-structural loading processes. A better understanding of this phenomenon will permit the development of improved design tools to ensure steam generator safety. This Thesis presents the results of an experimental laboratory study of the transient loading of a sectional model of steam generator tubes during a simulated two-phase blowdown. The research was carried out in a purpose designed and built experimental facility. The thermodynamic phenomena were investigated through dynamic pressures and temperatures. The transient tube loads were directly measured using dynamic load cells. The working fluid was R-134a and the tube bundle was a normal triangular array with a pitch ratio of 1.36. Preliminary testing indicated parasitic loading on the instruments and remedial actions were taken to ensure measurement accuracy. The success of the instrumentation development methodologies was validated in a series of single- phase blowdowns. Two-phase blowdown experiments were then conducted with various levels of liquid and numbers of tube rows. The results provided hitherto unknown information relating the nature of the fluid-structure interaction and flow development during a two-phase transient blowdown across a tube bundle. The pressure drop across the tube bundle established the thermal hydraulic fluid behaviour in the pressure vessel and controlled the upstream fluid discharge from the system. The flow through the bundle was choked for the majority of the transient. The transient tube loading was explained in terms of the associated fluid mechanics and the maximum load was compared with existing models obtained under steady flow conditions. An empirical model was developed that enables the prediction of the maximum tube loads once the pressure drop is known.

Thesis

Doctor of Philosophy (PhD)

The design of nuclear plant systems requires that public safety be ensured for the worst-case imaginable accident scenarios. This means that radioactive materials produced by nuclear fission must be safely contained. If the main steam pipe from a nuclear steam generator were to break, the water in the steam generator would rapidly boil off in what is called a blowdown. Such an event could produce significant loading on the heat exchanger tubes. Should the tubes rupture, radioactive materials may breach reactor containment. Thus, knowing the tube loading during this hypothetical scenario is an important input for safe design. The goal of this research is to improve our understanding of the effects of this postulated accident on the transient loading of the tubes. A laboratory study was carried out to simulate the blowdown. The experimental results provided valuable insights and guidance for the development of improved design tools.

▼ ENGLISH ABSTRACT: The generation of ultrafast light pulses and the development of time resolved spectroscopic techniques, such as the femtosecond pump probe spectroscopy technique, have facilitated the study of ultrafast energy transfer in the photosynthetic systems of green plants and photodynamic therapy drugs. It has allowed the investigation of biological and chemical processes that take place on the ultrafast timescale and has allowed us to obtain spectral and kinetic information on energy transfer. In addition, it has allowed time resolved experiments in which the transient absorption of species under investigation was observed and has elucidated molecular dynamics. In the present work this was done with a temporal resolution of approximately 200 fs and covering a pump-to-probe delay range of 300 fs to 2 ns. The main aims of this study were to characterise the femtosecond pump probe spectroscopy system, to investigate the energy transfer in the natural light harvesting complex II (LHC II) in view of future expansion to the study of synthesized arti cial functional light harvesting complexes and nally to study ultrafast processes in zinc phthalocyanine (ZnPc) systems. In photosynthetic organisms, LHC II is the most abundant light harvesting complex and it plays an important role in light harvesting and photoprotection. The light energy is absorbed by light harvesting complexes and transferred to a reaction centre (RC) in an ultrafast timescale. Phthalocyanines are a new class of photosensitiser used for photodynamic therapy. These drugs are used to treat small and super cial tumours. The energy transfer from the singlet excited state to the triplet excited state occurs on an ultrafast timescale. However, recent work done on zinc phthalocyanine has proved that the determination of the ultrafast component remains a challenge. Several ultrafast studies carried out on ZnPc in solvents have been not only unsuccessful to give a clear picture of the ultrafast dynamics but have also produced divergent results. In this study, a characterisation of the femtosecond pump probe spectroscopy setup was done. The samples under investigation were probed by a white light continuum. The generation of the white light continuum introduced chirp, which in uenced the temporal evolution of the transient absorption results. The technique used to correct the chirp introduced by white light generation is discussed in detail. Our femtosecond pump probe spectroscopy setup was benchmarked by using a well known dye, namely malachite green. In addition, the investigation of the transient absorption change of LHC II, an active component in photosynthesis, as extracted from spinach leaves and the ultrafast dynamics of a promising photosensitiser ZnPc in dimethyl sulfoxide (DMSO) as well as in dimethyl formamide (DMF) was done. The spectral and dynamic results obtained using these three samples are described and exponential ts to the absorbance decay curves used to estimate the timescales of the energy… Advisors/Committee Members: Du Plessis, Anton, Steenkamp, Christine M., Rohwer, Erich G., Stellenbosch University.

▼ In 2009, district data revealed that new students at Appoquinimink School District (ASD) were struggling academically and socially. Several specific steps were taken to improve the outcomes of these new students. First, an in-depth review of the relevant data regarding new students in the district was conducted. A white paper on relevant research about new students and successful strategies to support them was created to guide district efforts going forward. Based on these first two steps, goals were created and formalized in the district’s strategic plan to address new students’ needs. To achieve these goals, ASD adopted two key strategies: a beginning-of year data sheet and a New Student Orientation Handbook. The beginning-of-year data sheet provided school staff with valuable information on new students while the Handbook listed the supports that should be provided to new students. ☐ Based upon a “status check” conducted shortly after the New Student Orientation, improvement strategies were enacted. We concluded that the program was effective in increasing instructional staff awareness of who the new students were in their classes as well as their instructional needs. Additionally, there was evidence that some reduction in the discrepancy of discipline referrals between new and established students took place. ☐ An evaluation at the end of the school year examined both the fidelity of implementation of the orientation program and students’ and parents’ satisfaction with the program. An audit to determine whether student orientation procedures were followed revealed that many schools seemed to be inconsistently implementing key elements of the orientation program. Procedures were followed with more fidelity at the elementary level than at the secondary level. Although the majority of the schools provided welcome packets, completed the new student inventories, and provided the incoming students with at least some type of orientation to the school, the secondary schools often did not have their teachers or counselors provide a phone call home or create success plans for new students. Results of the student and parent surveys indicated that school staff were typically very welcoming to new students and opened to assisting them when they needed help. Additionally, the students and parents both reported relatively positive experiences and reported being largely satisfied with their new school. Analyses of academic achievement data suggested that both new and established students saw the same amount of within-year scale score growth, but new students started the school year significantly underperforming established students (in both ELA and Math) and also ended the year underperforming, too. ☐ Based upon these findings, three recommendations were made. First, we should focus our efforts on providing new students a formal orientation to the school and strengthening communication regarding their child’s progress to the parents of new students. Orientation activities promised to parents and students upon registration… Advisors/Committee Members: Wong, Carol.

▼ Transient ischaemic attacks (TIAs) are a warning sign for stroke. The early assessment and management of TIA can decrease the subsequent risk of stroke but the best model of care for TIA has not been established. General practitioners (GPs) in primary care have a significant role in secondary prevention for patients following a TIA and may also be the initial clinician assessing a patient with a suspected TIA. The clinical diagnosis of TIA can be challenging and there is limited literature describing how GPs assess and manage TIAs in practice. Diagnosis and assessment can be assisted by clinical scores and imaging, but these tools may not be accessible or have not been validated specifically in primary care. GPs with special interests (GPwSI) have been involved in providing expert care in areas where access to a specialist may be limited, and a GPwSI in stroke and TIA could be valuable in a TIA care pathway. The aims of this research were to: 1. Determine GP knowledge on current stroke and TIA assessment and management. 2. Educate GPs on the assessment of acute neurological symptoms and the early management of TIA. 3. Examine if additional tools that assist in the assessment and diagnosis of TIA including plasma protein biomarkers can be used in primary care. 4. Determine if a collaborative strategy for TIA management, using GPwSI in a community-based rapid-access TIA clinic (COMBAT clinic) linked with a specialist-based, hospital Rapid Access Clinic (RAC) is a feasible model of TIA care. 5. To assess the role of imaging in a community-based TIA clinic. Methods and Findings A cross-sectional study of GPs in Western Adelaide was conducted to determine the knowledge of TIA assessment and management, and identify perceived barriers. This self-administered questionnaire of 32 GPs found knowledge deficits in TIA care especially diagnosis and treatment. Participants also identified access to neurology specialists as a barrier and that specific education for GPs was needed. This research highlighted the need to improve TIA knowledge amongst GPs with education specifically designed for general practice and that improvement was needed in management pathways of TIA care locally, including access to specialist opinion. A number of resources were thus developed to educate GPs and improve their knowledge and confidence around TIA care. A review of the literature was undertaken and published for GPs specifically. Given the difficulty in diagnosing TIAs and the numerous mimics that may present in primary care, an approach to a “funny turn” was developed and published in a “10-minute consultation” format. GPs respond to different modalities of education delivery and as such two further learning modules were developed. A self-directed learning module was developed for GP registrars and a case of a “funny turn” was written for the independent GP learning program “check”. Time limitations in GP consultations can be a barrier to effective assessment and a comprehensive clinical neurological examination may be a challenge.

▼ Transient absorption spectroscopy has been employed to investigate three photo–active compounds; azobenzene, foldamer controlled by azobenzene, and oxazine. These compounds all have absorption in the ultra–violet regions responsible for their photo–active behavior. Due to this, the current transient absorption setup has been modified to extend the probing wavelength range to 320–650 nm, with the possibility of exciting the photo–active molecule in the ultra–violet. Azobenzene is valuable in benchmarking and optimizing the transient absorption setup, it shows that the detection window has been extended out to 320 nm. By resolving the ground state bleach we have added support for the assignment of the final decay to thermalization in the ground state. Comparison of relaxation lifetime in acetonitrile and tetrahydrofuran shows no noticeable change in the photophysics of isomerization between the two solvents. The foldamer family excited state relaxation is similar to azobenzene. There is an extension in the S₁ branching lifetime from 1.1 ps in azobenzene to 1.7 ps for foldamer 1 and 4.2 ps for foldamer 2. The separation of branching on the S₁ surface and relaxation through the S₁ to electronic ground state intersection was possible by comparison of azobenzene and foldamer family. The solvent effects show little difference for all members of the foldamer family expect for foldamer 2, suggesting that the dynamics of the azobenzene moiety are not affected by the larger macro–structure of the foldamer. For oxazine it has been established, by varying solvent polarity, that isomerization happens through three states; bond breakage, transfer to a dark state, and the final photo–isomer. This is confirmed by further studies completed after the introduction of electron withdrawing fluorine atoms. Carbon–oxygen bond cleavage occurs on the picosecond timescale, with solvent dependent rotation occurring in hundreds of picoseconds. Fluorinated oxazine shows a strong solvent dependence with rotation suppressed for all but the most polar of solvents. Advisors/Committee Members: Hodgkiss, Justin.
