▼ Joint Base Elmendorf-Richardson (JBER), which is a combined United States Army/Air Force installation, and neighboring Anchorage, Alaska, support a population of moose Alces alces (Linnaeus, 1758) that inhabit a fragmented landscape of habitat types interspersed with human development. Because development plans in support of the military mission may have significant impacts on moose movement in the area, JBER and Alaska Department of Fish and Game (ADF&G) biologists began a study of moose habitat use and behavior on JBER. In order to help identify behaviors in wild radio-collared moose captured on JBER, we tested Telonics tri-axial accelerometers for accuracy in the detection of activity and the identification of behaviors in radio-collared moose. Direct observations of three captive animals fitted with radio collars containing accelerometers allowed us to calibrate activity readings to observed behaviors. We developed four datasets in order to test whether readings from this type of accelerometer could identify specific behaviors (browsing, grazing, walking, standing, lying), behavior categories (feeding, traveling, resting), or simply when moose were active or inactive. Multiple threshold criteria were tested in order to maximize correlation to observed behaviors. The highest overall accuracy was achieved when using threshold criteria to characterize behaviors as active (92.29% accuracy) or inactive (90.64% accuracy). A Fisher’s Exact Test indicated that there was no significant difference between observed behaviors and those correctly classified using threshold criteria for either active (p = .9728) or inactive (p = .9431) behaviors, indicating that our threshold criteria is correctly classifying these behaviors. In the next phase of this study, we collected 244,957 GPS locations from 18 female moose captured on JBER and fitted with GPS collars equipped with the same model tri-axial accelerometer used in the captive trials. Data from the accelerometers were used to characterize moose behavior as active or inactive. GPS locations, along with behavior patterns and movement characteristics, were used to rank JBER habitat types. Turning angle and speed were calculated between successive locations for each animal across the animal’s home range. Values were pooled for all animals and used to assess movement characteristics by season and habitat type. The highest velocity recorded for a 60 minute period was 1.50 m/s (5.40 kph), and 99.50% of all steps had velocities < 0.26 m/s (0.94 kph). Turning angle groups did not vary among either habitat types (p = 1.00) or seasons (p = 0.99). A new, intuitive home range estimation method, Dynamic Potential Path Area (dynPPA), was used to incorporate behavioral states into the delineation of animal home ranges. We delineated dynPPA home ranges by season for each moose, and used this technique in combination with Jacobs Index (which measures utilization in relation to availability) to determine habitat preference. Seasonal dynPPA home range sizes averaged 15.28 km2 in… Advisors/Committee Members: Rittenhouse, Larry (advisor), Farley, Sean (advisor), Meiman, Paul (committee member), Peel, Kraig (committee member).

▼ The field of robotic path planning is rich and diverse. As more complicated systems have become automated, the need for simple methods that can navigate high dimensional spaces has increased. However, most path planning methods, such as Road Map methods and Search methods, increase exponentially with dimension, making them undesirable for complex robotics. Thus, the Secant and Traveling Artificial Potential Field (TAPF) approaches were developed. The Secant and TAPF approaches are modifications to the general Artificial Potential Field (APF) path planning algorithm with desirable properties, which make them ideal for path planning in high dimensional space. All APF methods grow linearly with dimension; however, general APF methods are not guaranteed to converge given an arbitrary field of obstacles, significantly hindering the applicability of the APF algorithm. By specially tuning the artificial forces generated by the Secant and TAPF approaches, these methods can be shown to be globally asymptotically stable at the target location for a point robot in a field of point obstacles. To extend this theory for more practical applications, the concept of a boundary layer was introduced into the path planning algorithm. The boundary layer is a finite radius that encompasses an obstacle, such that the field is transformed within the boundary layer to account for the solid shape. By warping the landscape within the boundary layer, the system becomes mathematically equivalent to avoiding a point in space. From these advancements, the Secant and TAPF approaches were then demonstrated on planar robots and manipulators. These real-world systems were handled by selecting individual points on the robot that need to converge and treating them as separate systems coupled together by the defined constraints. For example, a planar robot is dynamically equivalent to two points constrained by a link. Similarly, a manipulator could be considered to be n-points jointed together. With the use of the Secant and TAPF approaches to the APF algorithm, robotic control and path planning could be drastically simplified, even for complex systems.

▼ Robotics has been the subject of academic study from as early as 1948. For much of this time, study has focused on very specific applications in very well controlled environments. For example, the first commercial robots (1961) were introduced in order to improve the efficiency of production lines. The tasks undertaken by these robots were simple, and all that was required of a control algorithm was speed, repetitiveness and reliability in these environments. Now however, robots are being used to move around autonomously in increasingly unpredictable environments, and the need for robotic control algorithms that can successfully react to such conditions is ever increasing. In addition to this there is an ever-increasing array of robots available, the control algorithms for which are often incompatible. This can result in extensive redesign and large sections of code being re-written for use on different architectures. The thesis presented here is that a new generic approach can be created that provides robust high quality smooth paths and time-optimal path tracking to substantially increase applicability and efficiency of autonomous motion plans. The control system developed to support this thesis is capable of producing high quality smooth paths, and following these paths to a high level of accuracy in a robust and near time-optimal manner. The system can control a variety of robots in environments that contain 2D obstacles of various shapes and sizes. The system is also resilient to sensor error, spatial drift, and wheel-slip. In achieving the above, this system provides previously unavailable functionality by generically creating and tracking high quality paths so that only minor and clear adjustments are required between different robots and also be being capable of operating in environments that contain high levels of perturbation. The system is comprised of five separate novel component algorithms in order to cater for five different motion challenges facing modern robots. Each algorithm provides guaranteed functionality that has previously been unavailable in respect to its challenges. The challenges are: high quality smooth movement to reach n-dimensional goals in regions without obstacles, the navigation of 2D obstacles with guaranteed completeness, high quality smooth movement for ground robots carrying out 2D obstacle navigation, near time-optimal path tracking, and finally, effective wheel-slip detection and compensation. In meeting these challenges the algorithms have tackled adherence to non-holonomic constraints, applicability to a wide range of robots and tasks, fast real-time creation of paths and controls, sensor error compensation, and compensation for perturbation. This thesis presents each of the above algorithms individually. It is shown that existing methods are unable to produce the results provided by this thesis, before detailing the operation of each algorithm. The methodology employed is varied in accordance with each of the five core challenges. However, a common element of… Advisors/Committee Members: Weir, Michael (advisor).

▼ Mobile robots are widely used in many applications in industrial fields as well as in academic and research fields. The robot path planning problem is a key problem in making truly autonomous robots. It is one of the most important aspects in mobile robot research and plays a major role in their applications but is a complex problem. The role of path planning of mobile robot can be described as finding a collision free path in a working environmentenriched with obstacles from a specified starting point to a desired destination position called the goal. Additional characteristic of path planning in known environments is to satisfy some certain optimization criteria. Most of the traditional path planning approaches such as visibility graphs, cell decomposition, voronoi diagram, etc. are designed and functioning well in static known environments. However the real environments are consisting of both the stationary and moving obstacles. Artificial potential field based methods can be applicable for both the static and dynamic environments as well as for the known or unknownenvironments. Because of the analytical complexity of the dynamic environments, researchon path planning in dynamic environments is limited but there are hundreds of research workhave been reported on path planning in static known environments.Because of the mathematical simplicity, easy implementation and real time applicability ofartificial potential field, it has become popular in robot path planning. However, the potential field based path planning shows some inherit shortcomings such as dead-lock. Recently, in the field mobile robotics, some different techniques have been proposed to overcome the dead-lock issue associated with the artificial potential field based path planning. Most of these research work targeted only a specified situation where the dead-lock can happen.In this research, we proposed a method for avoiding robot from dead-lock caused in differentsituations of mobile robot path planning using artificial potential field. In the proposedmethod we have introduced a new repulsive force component which is depended on therobot’s heading direction. The proposed method is evaluated for different conditions whichcreate dead-lock for traditional artificial potential field method. The simulations of theproposed approach have indicated that it has a capability of avoiding dead-locking associatedwith the traditional method, and is simpler and easier to implement. However in realimplementation it is required to extract the geometric features of the environment such aswalls and corners for our consideration in structured environments. Consequently, we havediscussed a segmentation and feature extraction adaptive algorithm for structuredenvironments. In this study, several adaptive techniques proposed in literature forsegmentation of laser range data have been implemented and tested in different environmentsto compare the performances of them with the proposed technique. The experimental resultshave shown that the proposed method is superior to… Advisors/Committee Members: 石井, 和男.

Developing regions are often characterized by large areas that are poorly reachable or explored. The mapping and census of roaming populations in these areas are often difficult and sporadic. A recent spark in the development of small aerial vehicles has made them the perfect tool to efficiently and accurately monitor these areas. This paper presents an approach to aid area surveying through the use of Unmanned Aerial Vehicles. The two main components of this approach are an efficient on-device deep learning object identification component to capture and infer images with acceptable performance (latency andaccuracy), and a dynamic path planning approach, informed by the object identification component. In particular, this thesis illustrates the development of the path planning component, which exploits potential field methods to dynamically adapt the path based on inputs from the vision system. It also describes the integration work that was performed to implement the approach on a prototype platform, with the aim to achieve autonomous flight with onboard computation. The path planning component was developed with the purpose of gaining information about the populations detected by the object identification component, while considering the limited resources of energy and computational power onboard a UAV. The developed algorithm was compared to navigation using a predefined path, where the UAV does not react to the environment. Results from the comparison show that the algorithm provide more information about the objects of interest, with a very small change in flight time. The integration of the object identification and the path planning components on the prototype platform was evaluated in terms of end-to-end latency, power consumption and resource utilization. Results show that the proposed approach is feasible for area surveying in developing regions. Parts of this work has been published in the workshop of DroNet, collocated with MobiSys, with the title Surveying Areas in Developing Regions Through Context Aware Drone Mobility. Thework was carried out in collaboration with Alessandro Montanari, Alice Valentini, Cecilia Mascoloand Amanda Prorok.

▼ The Dynamic Voltage Scaling (DVS) technique has proven to be ideal in regard to balancing performance and energy consumption of a processor since it allows for almost cubic reduction in dynamic power consumption with only a nearly linear reduction in performance. Due to its virtue, the DVS technique has been used for the two main purposes: energy-saving and temperature reduction. However, recently, a Dynamic Voltage Scaled (DVS) processor has lost its appeal as process technology advances due to the increasing Process, Voltage and Temperature (PVT) variations. In order to make a processor tolerant to the increasing uncertainties caused by such variations, processor designers have used more timing margins. Therefore, in a modern-day DVS processor, reducing voltage requires comparatively more performance degradation when compared to its predecessors. For this reason, this technique has a lot of room for improvement for the following facts. (a) From an energy-saving viewpoint, excessive margins to account for the worst-case operating conditions in a DVS processor can be exploited because they are rarely used during run-time. (b) From a temperature reduction point of view, accurate prediction of the optimal performance point in a DVS processor can increase its performance. In this dissertation, we propose four performance improvement ideas from two different uses of the DVS technique. In regard to the DVS technique for energy-saving, in this dissertation, we introduce three different types of margin reduction (or margin decision) techniques. First, we introduce a new indirect Critical Path Monitor (CPM) to make a conventional DVS processor adaptive to its given environment. Our CPM is composed of several Slope Generators, each of which generates similar voltage scaling slopes to those of potential critical paths under a process corner. Each CPR in the Slope Generator tracks the delays of potential critical paths with minimum difference at any condition in a certain voltage range. The CPRs in the same Slope Generator are connected to a multiplexer and one of them is selected according to a current voltage level. Calibration steps are done by using conventional speed-binning process with clock duty-cycle modulation. Second, we propose a new direct CPM that is based on a non-speculative pre-sampling technique. A processor that is based on this technique predicts timing errors in the actual critical paths and undertakes preventive steps in order to avoid the timing errors in the event that the timing margins fall below a critical level. Unlike direct CPM that uses circuit-level speculative operation, although the shadow latch can have timing error, the main Flip-Flop (FF) of our direct CPM never fails, guaranteeing always-correct operation of the processor. Our non-speculative CPM is more suitable for high-performance processor designs than the speculative CPM in that it does not require original design modification and has lower power overhead. Third, we introduce a novel method that determines… Advisors/Committee Members: Abraham, Jacob A. (advisor).

▼ With the explosion of e-commerce in recent years, there is a strong desire for automated material handling solutions including warehousing robots. Cable driven parallel robots (CDPRs) are a relatively new concept which has yet to be explored for high-speed pick-&-place applications in the industry. Compared to rigid-link parallel robots, a CDPR possesses significant advantages including: large workspace, low moving inertia, high-speed motion, low power consumption, and incurring minimal maintenance cost. On the other hand, the main disadvantages of the CDPRs are the cable’s unilateral force exerting capability and low rigidity which is resulting in undesired vibrations of their moving platform. Kinematically-constrained CDPRs (KC-CDPRs) include a special class of CDPRs which provide a considerably higher level of stiffness in undesired degrees of freedom (DOFs) via connecting a set of constrained cables to the same actuator. Nevertheless, undesired vibrations of the moving platform are still their main problem which request more attention and investigation. Dynamic modeling, stiffness optimization, vibration and trajectory-tracking control, and stiffness-based trajectory-planning of redundant KC-CDPRs are studied in this thesis. As a new technique, we separate the moving platform’s vibration equations from its desired (nominal) equations of motion. The obtained vibration model forms a linear parametric variable (LPV) dynamic system which is based for the following contributions: 1) Proposing a new tension optimization approach to minimize undesired perturbations under external disturbances in a desired direction; and demonstrating the effectiveness of kinematically-constrained actuation method in vibration attenuation of CDPRs in undesired DOFs. 2) Providing the opportunity of using a wide class of well-established robust and optimal LPV-based control methods, such as H∞ control techniques, for trajectory-tracking control of CDPRs to minimize the effect of disturbances on the robot operation; and showing the effectiveness of kinematically-constrained actuation method in control design simplification of such robots. 3) Proposing the concept of stiffness-based trajectory-planning to find the stiffness-optimum geometry of trajectories for KC-CDPRs; and designing a time-optimal zero-to-zero continuous-jerk motion to track such trajectories. All the proposed concepts are developed for a generic KC-CDPR and verified via numerical analysis and experimental tests of a real planar warehousing KC-CDPR.

▼ The mobility that wireless communication offers to users, added to the ease of installation have increased the demand on such communication systems. However, the main drawback of wireless communication is the degradation of the signal as it travels through the channel due to the different propagation mechanisms the signal undergoes. To minimise the effect of the channel and get the best service, the base stations must be appropriately located within the environment. This requires proper knowledge of the channel characteristics. Ray tracing software is used throughout this work to generate the channel characteristics of an indoor environment. After getting the channel characteristics, a novel cost function is defined based on the path loss values and it is then optimised. Once the optimal base stations’ positions are found, the minimal amount of power required to cover a predefined percentage of the possible receivers’ locations is calculated. On the other hand, a receiver’s position acquiring enough field strength does not necessarily enjoy the service. This depends on the time dispersion parameters values relative to the symbol rate. The time dispersion parameters have always been ignored in the literature while finding the optimal base stations’ locations. Three cost functions that take into consideration both the path loss and rms delay spread, for the first time in the literature, are therefore defined. The cost functions are optimised and their corresponding results are compared. Furthermore, indoor environments have always been considered static which is never realistic. They are subject to continuous changes such as opening doors and windows as well as the presence of people. The first detailed analysis and quantified results of the effect of a dynamic environment on the optimal base stations’ positions and minimal emitted power are presented. It is shown that the optimal base stations’ locations and minimal emitted power are sensitive to such environment changes. The environment changes can also disturb the service for active receivers. Three techniques to overcome the effect of environment changes and bring the disturbed service back to receivers are proposed. The first two techniques rely on increasing the emitted power or changing the antenna polarisation. The third technique is a novel technique that gives the base station the ability to automatically move in various directions within a limited distance. The techniques are tested and their efficiency and limitations are discussed.

▼ This dissertation contributes to the design of better policy implications and improvements of well-being among older adults, especially when resources are limited. This is done by using proper econometric methods and taking advantage of the richness of the Indonesian Family Life Survey, a panel data set containing detailed information for both respondents and their biological parents. ❧ Chapter 2 analyzes the health transmission from parents to their children when they become older adults. I match the health status of older respondents to parental characteristics (several health measures and education) to see if any correlations exist in Indonesia. I find that strong intergenerational correlations exist. For example, children having parents with more difficulties with ADLs are more likely to have the same problem as older adults. However, surprisingly, the magnitude of correlations becomes significantly lower for those born in richer areas of Indonesia such as Java and Bali. This suggests that the level of development at birth or early childhood, which may include having better health infrastructure, substitutes for the influence of parental health and hence highlights the importance of public policies that focus on community level infrastructure development in less developed areas, in order to solve health inequality. ❧ Chapter 3 examines the determinants of chronic health conditions and explains their persistence. I incorporate dynamics into a health demand function, finding strong correlations between lagged and current health measures when nothing else is controlled. This could represent the influence of lagged health or fixed unobserved factors such as genetic endowments and childhood health. To disentangle these, I estimate the influence of lagged health by using first-difference two-step generalized method of moments (FD-GMM), where the first-differencing removes fixed unobserved factors and keeps only lagged health. I found that it is this fixed effect, representing both genetic endowments and early life cycle including childhood health, that is most important in explaining later life chronic conditions. The impact of past health conditioning on the fixed effect, captured by the coefficients on lagged health measures, is weak, with estimated coefficients relatively close to zero. These results are robust to potential measurement errors in health and to sample attrition. Socio-economic status also has very little influence on current health, again conditioned on the fixed effect and on the influence of lagged health. In order to investigate if past health has different impacts across demographic or economic groups, I disaggregate the sample across age, household per capita expenditure level (PCE), and years of education. The results show that those with less education tend to show more persistence, compared to those with higher education. ❧ In developing countries like Indonesia, health disparities are serious issues since they persist over generations due to the lack of proper interventions and also prevail… Advisors/Committee Members: Strauss, John A.

▼ A particular class of optimisation problems can be solved using a technique known as dynamic programming. This technique applies to problems that have many possible solutions, each consisting of a number of individual decision points. In theory, a globally optimal solution relative to a given metric can be obtained by recursively choosing the most optimal option at each decision point. In practice, however, applications of dynamic programming are computationally expensive for the scale of real-world domains.This thesis examines the existing array of robot motion planning algorithms and applications, a core application of dynamic programming for ground and aerial vehicles. In particular, the thesis highlights that the sequential nature of traditional algorithms does not scale in practice as modern central processing units begin to reach physical limits in terms of computational throughput. This thesis then outlines current parallel processing unit architectures that have emerged in the last decade with particular focus on graphical processing units.The main contribution of this thesis is a new class of concurrent dynamic programming algorithms that are applicable to multi-core processor architectures. The core mechanic of the algorithms is proven to generate an equally optimal global solution to existing sequential algorithms, with a computational complexity of O(n), assuming enough cores are available relative to the problem size. Various implementation flavours are developed and benchmarked over a variety of two-dimensional configuration spaces, with the most efficient being able to plan on the scale of the main campus of the University of New South Wales (a 1000m x 500m area) with 1m x 1m resolution in sub-second time.Higher dimensional configuration spaces are also investigated with a proof-of-concept experiment presented to assess the feasibility and performance as the dimensionality increases – a factor notorious in traditional approaches that increases the computational complexity exponentially. The work presented here gains an increased concurrent benefit as the dimensionality of the problem increases and hence is able to perform an order of magnitude more efficiently in the presented three-dimensional experiments.Designing concurrent algorithms can be more difficult, but the implementation benefits will continue to increase as the level of parallelism found in modern hardware approaches that found in nature.

This report presents the results of the graduation thesis from the TU Delft, performed at the Integrated Vehicle Safety department of TNO. The goal of this graduation project is to develop a unified path planning and tracking method for autonomous vehicles in highway driving scenarios, by making use of Artificial Potential Fields (APFs). Most autonomous vehicles base their navigation control on first planning a path, which is then tracked by using a combination of feedback and feedforward control. The strength of using APFs is the possibility to integrate the path planning and tracking process. This concept has been extensively used in the field of robotics. The attractive and repulsive forces coming from the APF guide the robot towards the final goal while avoiding obstacles. This offers an intuitive way to represent the level of hazard experienced in the direct environment. However, considerably less research has been devoted to the application of APFs in the field of autonomous vehicles. Furthermore, the available research mostly treats the vehicle as a particle, thereby leaving out the more complicated vehicle dynamics. Therefore, this research is aimed at including the vehicle dynamics into the path-planning process such as to generate feasible and desirable paths. A Model Predictive Control (MPC) framework is proposed to fulfill this task. The adopted vehicle model is given by the linear bicycle model, which represents the vehicle dynamics sufficiently well for highway applications. The two main manoeuvers of lane keeping and lane changing are executed with the aid of two different APFs that were designed for these specific purposes, respectively. A second order Taylor approximation is used to incorporate the APFs into the quadratic MPC cost function. The Simulink model from TNO to simulate the controlled vehicle is modified by extending it to curved roads and by including the developed APF MPC algorithm. The resulting algorithm is capable of following curved highway lanes and overtaking slower vehicles at different velocities in the simulation environment. The results are compared with the previously developed path planner and lateral controller from TNO. In order to also deliver longitudinal control action, the model can be connected to the adaptive cruise control application of TNO. It is concluded that the suggested method potentially offers a powerful solution to the navigation control of autonomous vehicles. Real-life experiments have to be done in the future to validate the performance of the controller.

▼ This thesis presents the study of weakly bound clusters in the ground state (or the zero-temperature limit) using path integral molecular dynamics. Specifically, we look individually at the quantum properties of small clusters of hydrogen and water molecules and confined hydrogen within water cages, known as clathrate hydrates, which serves as a more practical application. Clathrate hydrates have been extensively studied as a clean storage container for molecular hydrogen and there have been discrepancies on the hydrogen occupancy number between various theoretical and experimental studies. It has been shown that the occupancy number is sensitive to the potential energy surfaces and models of the hydrogen and water systems. A preliminary study of hydrogen contained in clathrates is performed using a traditional hydrogen pair potential and water-hydrogen interaction potential. Hydrogen occupancy and structural distributions are compared to literature values. Small clusters of the individual molecules themselves are then focused on. The molecular hydrogen pair potentials are evaluated by calculating the Raman vibrational shift, a property that is very sensitive to the interaction potential, and comparing to experimental measurements. These shifts are calculated using first order perturbation theory based on pair distribution functions generated from Langevin equation path integral ground state (LePIGS) simulations for all bosonic isotopologues. It is determined that the shifts calculated using the Hinde pair potential give better agreement to experimental results than the traditional hydrogen potentials that we have been using in the past. The perturbation theory approach is then compared with two exact methods to calculate the shifts. For the application of hydrogen clusters, it is determined that perturbation theory is the best choice when balancing accuracy and precision. In the literature, there has been a discrepancy in the shape of the chemical potential at low temperature and in the ground state. We calculate the ground state chemical potential using LePIGS and find agreement with other PIGS results. We then extend our LePIGS code to simulate flexible molecules by investigating the water dimer. Ground state energies, dissociation energies, and structural properties are calculated using two empirically based interaction potentials and one ab initio potential, MB-pol, that includes polarizability and many-body effects which has been shown to reproduce experimental dissociation energies. We further demonstrate that imaginary time correlation functions generated from LePIGS can be used to calculate accurate vibrational transition energies. This work serves as a demonstration of the effectiveness of the LePIGS method towards calculating ground state properties of small clusters and provides useful information on the interaction potentials that should be used for systems containing hydrogen or water, specifically hydrogen contained in a flexible clathrate hydrate. An analytic form of the 1-D Hinde pair potential for…

▼ Genale – Dawa river basin is one of the twelve river basins in Ethiopia with catchment area of 74,010 Km 2 and has the third largest surface area (about 170,000km 2 ) after Wabishebele and Abay River basins. Genale-Dawa river basin has an estimated hydro power potential of 9,300 GWh/year and is expected to contribute about 5.8% of the total estimated potential of the country. Out of the nine large scale hydropower potential projects in the basin, this study deals with the optimal operation of the cascade hydropower plants namely, GD-3, GD-5 and GD-6 that are located on the main river channel of Genale River. The upper most hydropower plant, GD-3, is already under construction and the other two are under study. The latest version of HEC-ResSim (Version 3.1) introduced by U.S. Army Corps of Engineers in 2013 is used to simulate the multi-reservoir system network. The physical and operational data are obtained from previous studies of these projects and used as input in reservoir network module of ResSim Model. Implicit (default) and Explicit (user defined) system storage balance has been used to get the maximum power and energy and plot the optimal guide curve so as to be used by the operator to attain the optimal overall energy generated from the system. The explicit system storage balance has generated a better power and energy for the reservoir system. The study showed that, when the individual hydropower reservoirs deliver energy and capacity into a common power system, operating the projects as system has produce more average energy or firm energy than the sum of individual projects operating independently. The maximum overall average energy of the system found in this study is 4417.7GWh/yr. Comparing with the feasibility study, the proposed model is capable to produce an extra amount of 487.7 GWh average electrical energy (a 12.4% increment) annually. The optimal guide curve denotes that there is a tendency, in the optimal explicit system storage, to leave more water from GD-3 reservoir and prepare the storage to hold more water during high flood seasons. The water released from this reservoir can generate additional power at the downstream power plants. The reverse is true for the operation of the downstream power plants. The pool level of GD-5 is almost in the flood zone except for the first three months, January to March, where the pool level is in the active live storage zone. In GD-6 the reservoir pool level is in the flood zone throughout the year. Advisors/Committee Members: Dr.-Ing Dereje Hailu (advisor).

У овој дисертацији се разматра утицај ефеката динамичке поларизације на каналисање наелектрисаних честица кроз различите типове једнослојних угљеничних наноцеви (SWNT). На почетку анализе разматра се интеракција наелектрисаних честица са четири различита типа наноцеви у оквиру линеаризованог дводимензионог једнофлуидног и двофлуидног хидродинамичког модела. Типови наноцеви који се разматрају су SWNT(6, 4), SWNT(8, 6), SWNT(11, 9) и SWNT(15, 10). Поменути хидродинамички модели се користе за рачунање потенцијала лика где се на тај начин разматра утицај на кретање наелектрисаних честица дуж путање паралелне са осом наноцеви. Брзине кретања протона се узимају у опсегу од 1 до 10 a.u.. Протон средње кинетичке енергије (реда MeV) изазива појаву снажне динамичке поларизације валентних електрона на омотачу наноцеви што као ефекат има индуковање значајне силе лика на протон, односно појаву губитака енергије услед ексцитације поменутих електрона. Показано је да динамичка сила лика изазива снажан утицај на угаону расподелу каналисаних протона кроз кратке наноцеви. Установљено је да су ове нове појаве посебно изражене када се брзина каналисаних честица поклапа са фазном брзином квазиакустичног π плазмона. Анализа је укључила генерисање нумеричких резултата којима је приказан утицај фактора пригушења, радијуса наноцеви и почетне позиције каналисане честице на потенцијал лика унутар наноцеви. Извршено је поређење добијених резултата за потенцијал лика за случај једнофлуидног и двофлуидног модела за различите типове наноцеви. Такође је извршена рачунарска симулација каналисања честица као и поређење просторне и угаоне расподеле каналисаних честица у случају поменутих хидродинамичких модела. У наставку се анализира интеракција протона са SWNT(6, 4) где се узимају у обзир ефекти динамичке поларизације у оквиру дводимензионог проширеног хидродинамичког модела. Овај модел се користи за аналитичко и нумеричко рачунање потенцијала лика и зауставне силе на протон који се креће паралелно са осом наноцеви у случајевима када је трајекторија његовог кретања унутар и ван наноцеви. Опсег брзина који се разматра је од 0.5 до 15 a.u.. Разматра се утицај ефеката различитих угаоних модова на зависност потенцијала лика од брзине протона за различите типове наноцеви. Такође се рачуна просторна и угаона дистрибуција протона у случају проширеног двофлуидног модела и пореди са случајем обичног двофлуидног модела са нултим фактором пригушења. На крају се анализира интеракција наелектрисаних честица са правим и закривљеним једнослојним наноцевима при условима каналисања када је урачуната динамичка поларизација валентних електрона угљеника. Поларизација је описана линеаризованим двофлуидним хидродинамичким моделом са параметрима одређеним из неколико независних експеримената у вези са спектроскопијом губитака енергије у угљеничним наноструктурама. Хидродинамички модел се користи за израчунавање потенцијала лика…
