Abstract:
In the history of Buddhism in China, three major persecutions took place between the fifth and the ninth centuries. In the present research, I propose to study them together and in their broader context as a means of understanding the relationship between Buddhism and the state in medieval China. Although a further episode of repression of the Buddhist community occurred in southern China in the tenth century, I will argue that the first three great persecutions marked a fundamental transition in the interaction between Buddhism and Chinese society. As an attempt to study the social and political history of Buddhism in medieval China, this thesis shall accord some space to the development of the monastic community and economy during the time under examination. It will furthermore lay emphasis on the long-term factors of Buddhist development, thus hoping to shed new light on the cultural, economic, social and political reasons for the religious persecutions. As these persecutions were carried out under the orders of the ruling secular authorities, and most of the assumed reasons are related to the imperial policies, the present research is a case study through which the interaction between Buddhism and the state in medieval China will be investigated.

A pure pursuit guidance law is combined with a heading autopilot to provide accurate path keeping of submersible vehicles. The scheme is implemented and analyzed in both the horizontal and vertical planes. A complete stability analysis is performed in order to evaluate regions of stable vehicle operations. Numerical integrations support the analytic predictions. Two distinct stability boundaries are established. In the first, the vehicle loss of stability is accompanied by the generation of oscillatory motions around the commanded path. In the second, loss of stability occurs with linearly increasing path deviation. The horizontal and vertical plane schemes are combined with a propulsion control law in order to achieve path tracking of a general commanded route composed of several straight line segments in three dimensional space.

Abstract:
In this comparative study, the author investigated the differences between the tathāgatagarbha in the rNyingma’s teaching and Lao Tzu’s Dao based on qualitative-based interpretivism paradigm. The purpose of this paper is about decoding the concept of the tathāgatagarbha in both academy-based methodology and practitioner-oriented view, and therefore the meanings of the Dao from a new dimension will be revealed. Through this paper, readers are able to see the worldviews and the core teachings of both great wisdoms are fundamentally different, but in some parts they are mutually interpenetrated and interlaced. The analysis of this paper is determined by the examination of ancient Buddhist sutras, Daoist scriptures, scholarly periodicals, online journals, the Buddhist books written by the rNying ma masters, and the authoritative Daoist scholars in the Chinese academic circle. The results reveal the idea of the Dao in the Dao De Ching is essentially different the establishments of the fourfold dependent origination and the three verses of the Great Perfection in the tathāgatagarbha system of the rNying ma school; nonetheless, there are some complex relationships between the function of the tathāgatagarbha and the faculty of the Dao.

Ferrecchia, Antonella. "Analysis of three-dimensional dynamic stall." Thesis, University of Glasgow, 2002. http://theses.gla.ac.uk/4429/.

Full text
Abstract:
The work presented in this thesis attempts to provide a deeper understanding of the physical phenomena associated with the dynamic stall process on finite wing planforms. The work involves the analysis of data from the Glasgow University unsteady aerodynamics database that has been built up over a number of years through contributions from a range of researchers. Analysis focuses on two finite wing models; one a rectangular wing of aspect ratio three and the other with the same overall dimensions but with 60o swept tips. However, as most research to date has focused on nominally two-dimensional data, the results are referenced to measurements made on a nominally two-dimensional NACA 0015 aerofoil model. This is appropriate as this aerofoil was used as the wing section of both of the three-dimensional wing models. Flow visualisation images collected in a previous study also provide valuable information to supplement the pressure analysis. It is shown that, although the flow at the mid span sections of the finite wings exhibit many of the features of the two-dimensional case, there are some significant differences. In particular, the three-dimensional flow is dominated by the downwash from the wing tips. This causes the normal force response during pitching to lag the static normal force curve. This is in complete contrast to the two-dimensional case where the shed vorticity induces the opposite effect. The downwash also influences the incidence of lift stall but it does so in a manner that is dependent on the reduced pitch rate. Despite these effects, it is established that the flow behaviour in the mid-span region is almost two-dimensional prior to vortex inception. This provides an opportunity to examine the relationship between the generation of vorticity, or vorticity flux, in the leading edge region and the origins of the dynamic stall vortex at specific span locations in location. The vorticity flux distributions around the leading edges of the nominally two-dimensional NACA 0015 aerofoil and the two finite wings are then examined for pitching cases. On this basis a link is established between the peak vorticity flux and the dynamic stall vortex formation. This is confirmed by comparison of the vorticity flux measurements with a previous dynamic stall vortex detection method. The two methods are shown to five almost identical results in situations where the flow may be considered nominally two-dimensional. This suggests that monitoring vorticity flux may provide a practical method of dynamic stall vortex detection. In regions of the finite wings that exhibit strong three-dimensional flow effects, i.e. away from the mid-span, the peak vorticity flux is achieved after the dynamic stall vortex forms. This suggests that vortex formation is triggered by interference from adjacent sections of the wing. To examine this possibility, the vorticity flux is compared to a criterion used to detect the initial instability of the boundary layer at the leading edge. It is shown that the relationship between this criterion and the peak vorticity flux is the same along the span of the wing. This is a significant result as it demonstrates that, although the leading edge response determines the incidence of vortex onset near the mid-span, the formation of the vortex on sections of the wing closer to the tips occurs before the leading edge becomes critical. The implications of this for dynamic stall modelling of two-dimensional dynamic stall predictors with lifting line formulations will not capture this effect.

Dans cette thèse, nous avons étudié le passage des moteurs à combustion interne (ICE) aux véhicules à carburant alternatif (AFV) tout en considérant la dimension sociale via le concept de DJ. Cela nous a permis de mettre en évidence les nombreux compromis en jeu entre les différents instruments politiques ainsi qu'entre les trois piliers de la durabilité, et donc de les minimiser. Chacun des essais a examiné la transition vers les VAC sous un angle différent, chacun complétant les deux autres. Chacun des essais présente certaines limites qui ont été partiellement traitées dans les deux autres essais. Cependant, il reste beaucoup de travail à faire sur ce sujet à l'avenir
In this thesis, we have investigated the transition from internal combustion engines (ICE) to alternative fuel vehicles (AFV) while considering the social dimension via the concept of DJ. This enabled us to highlight the many tradeoffs at play between the different policy instruments as well as between the three sustainability pillars, and therefore to minimize them. Each of the essays looked at AFV transition from a different angle with each one complementing the other two. Each of the essays has some limitations that were partially dealt with in the other two essays. However, there remains plenty of work to be done on this subject in the future

Unmanned aerial vehicles are being incorporated in an increasing variety of operations. To take full advantage of the vehicles, the plans for the operations should integrate each vehicle's capabilities when planning the operations. This thesis focuses on planning operations for multiple, heterogeneous UAVs for the purpose of monitoring Earth's phenomena through data collection. The planning is done for flight in three dimensions. The problem also includes time window constraints for data collection and incorporates human input in the planning process. Two solution methods are presented: (1) a mixed-integer program, and (2) an algorithm that utilizes a meta-heuristic to generate composite variables for a linear program, called the Composite Operations Planning Algorithm. The suitability of the two methods to solve the operations planning problem is compared based on the ability of each of the methods to find high-value, feasible solutions for large-scale, operationally sized problems in a reasonable amount of time. The analysis shows that the Composite Operations Planning Algorithm can develop operations plans for problems including 15 UAVs and 5000 nodes in less than 25 minutes using a desktop computer.

Abstract:
This dissertation consists of three essays. The first essay estimates a demand function for compressed natural gas as a fuel substitute to diesel fuel for firms with hybrid fleets. The data is from the Energy Information Administration, for the years 1989 to 2009, for 47 states. Results show that an increase of $0.10 in the price of diesel fuel will increase compressed natural gas demand by 5.59%. The second essay focuses on regional trade agreements (RTAs). A number of studies have found that RTAs significantly increase members' trade flows. While recent studies have begun to explore the reasons for this, none have examined whether the RTA trade effect varies systematically with the number and type of policy areas covered by the agreement. While the empirical trade literature has shed considerable light on the trade-creating ability of RTAs (Grant and Lambert, 2008), much less is known about why these agreements are so successful. In this study, we draw on a new database from the World Trade Organization of trade policy areas covered by RTAs to examine whether the degree of trade liberalization is an important determinant of the RTA trade effect. An augmented, theoretically consistent gravity equation is developed to explore the effects of RTAs on trade, conditional on the policy areas they include. In particular, we investigate two policy areas that are particularly important for agricultural trade, sanitary and phytosanitary measures (SPS) and technical barriers to trade (TBT). The results suggest that harmonization of non-tariff measures inside RTAs matters: Agreements that liberalize these policies increase members' agricultural trade by an additional 62 percent compared to agreements that do not. We conclude that studying the components of RTAs -- in particular, the policy areas covered by these agreements -- is important when analyzing the determinants of RTA trade effects. The third essay uses Bayesian Model Averaging (BMA) to study the effect of membership in the General Agreement on Tariffs and Trade (GATT), the predecessor to the World Trade Organization (WTO), and the WTO on trade flows. Existing GATT/WTO literature is not univocal as to whether membership in the GATT/WTO increases trade flows. In this study, Bayesian model averaging (BMA) is used in the presence of theoretical uncertainty to address whether membership in the GATT/WTO plays a role in the gravity model. Several datasets are examined: a dataset from a previous study; and two datasets compiled for this study, world trade and agricultural trade. Results show, for all three sets of data, that membership in the GATT/WTO does belong in the gravity equation and increases trade flows.

Experiments were performed on a three-dimensional NACA 0015 foil with a 5.5 cm average chord and 24.3 cm span performing a combined roll and pitch motion. The trailing edge of the foil was tapered. The motion was produced by harmonically rolling and pitching the foil near the root using two-axis control. Tests to determine the mean thrust coefficient of the foil were conducted over a wide parametric space. This parameter space included two roll amplitudes, with induced heave (at the 0.7 span) to chord ratio of hO.7 / c = 1.00 and 1.50; respectively, with Strouhal numbers ranging from 0.20 to 0.80; and maximum angle of attack varying between 15 and 50 degrees. The angle of attack and Strouhal number were also defined using the motion at the 0.7 span. A planform area mean thrust coefficient of 2.07 was recorded for 40 degrees maximum angle of attack and h0.7 / c = 1.50. Experiments to measure the mean lift and thrust coefficient were performed after adding a static bias to the foil pitch. Mean lift coefficients of near 4 were achieved in this manner. Further maneuvering tests were accomplished by measuring the forces produced by an impulsively starting foil in still water and at U = 0.4 m/s. Peak forces and impulse were measured for pitch angles between 30 and 90 degrees and for three different roll velocities. The highest propulsive impulse measured was 2.25 Newton-seconds at a maximum roll amplitude of 1.28 m/s and pitch angle of 40 degrees. Wake velocities were measured using Laser Doppler Velocimetry (LDV) and Digital Particle Imaging Velocimetry (DPIV) in three ancillary experiments. First, mean velocities across the wake at five spanwise locations were recorded using LDV. The wake width was found to be the excursion of the foil at the 70% span, validating our previous assumption. In the second experiment, using LDV, we measured the phase-average velocity and produced a three-dimensional plot of the wake behind the foil at the 0.7 span. Finally, DPIV for the same flapping parameters map the velocity field in the wake for various foil positions in a half-cycle.

Abstract:
Three‐wheelers are popular in fuel efficient contests but do not see much commercial success. This could be because three‐wheelers are easier to tip over than four wheeled vehicles. One way to counteract the tipping over is to introduce leaning dynamics on three‐wheeled vehicles so that they lean in corners like bicycles and motorcycles can. For this project a small radio‐controlled three‐wheeler was built with a mechanical system to handle the leaning dynamics for the front wheel pair. For the leaning control two different controllers were programmed to be compared, one relying on feedback from an accelerometer. The other calculates the desired angle based on a mechanical model with feedback from a potentiometer that measures the current leaning angle. These controllers where tested indoors on a smooth surface and outdoors on a rough surface to compare the two. Both controllers performed well indoors but the controller relying on feedback from the potentiometer was more stable than the one relying on the accelerometer. Testing outdoors on a rough surface amplified the differences. That test showed that the controller using an accelerometer was so unstable it barely could provide any leaning at all while the one using a potentiometer delivered very similar result as indoors. This was probably due to the accelerometers sensitivity to vibration. The controller using the accelerometer for feedback was slower and more unstable but can keep the vehicle leveled on leaning ground since it measures the actual acceleration the vehicle experiences. The controller using a potentiometer for feedback was faster and more stable but only uses the leaning dynamic while turning without taking other accelerations into account.
Trehjulingar är populära i bränsleeffektivitetstävlingar men har inte sett mycket kommersiell framgång. Detta kan bero på att trehjulingar välter lättare än fyrhjulade fordon. Ett sätt att motverka vältningen är att introducera lutningsdynamik på trehjulingar så att de lutar in i kurvor som cyklar och motorcyklar. För det här projektet byggdes en liten radiostyrd trehjuling med ett mekaniskt system för att hantera lutningen med framhjulen. För att kontrollera lutningen designades två olika regulatorer för att jämföras, en som förlitar sig på feedback från en accelerometer och en som beräknar en vinkel enligt en mekanisk modell med feedback från en potentiometer som mäter fordonets nuvarande vinkel. Dessa regulatorer testades inomhus på en jämn yta och utomhus på en ojämn yta. Båda regulatorerna hade god prestanda inomhus men regulatorn som använde feedback från potentiometern var snabbare och mer stabil än regulatorn som använde accelerometern. Testen utomhus, på en ojämn yta, förstärkte skillnaderna mellan regulatorerna och visade att regulatorn som använder accelerometer var så instabil att den knappt kunde få trehjulingen att luta alls medan regulatorn som använde sig av potentiometern visade väldigt lika resultat som när den kördes inomhus. Det beror troligen på accelerometerns känslighet för vibrationer. Regulatorn som använde accelerometern var långsammare och mer instabil men kan hålla fordonet vågrätt på lutande mark eftersom den läser sann acceleration. Regulatorn som använde en beräknad vinkel och feedback från en potentiometer var snabbare och mer stabil men kan inte hålla fordonet vågrätt på lutande mark eftersom den inte tar hänsyn till den egentliga accelerationen.

Abstract:
Une étude expérimentale des sillages turbulents autour de géométries tridimensionnelles est conduite en augmentant leur complexité depuis les corps axisymétriques jusqu'aux véhicules automobiles. Quelle que soit la géométrie, deux types de mouvement cohérent sont susceptibles d'être observés dans le sillage. Tout d'abord, sur des échelles de temps de l'ordre de 5D/U, D et U étant respectivement la taille caractéristique du corps et la vitesse de l'écoulement, le sillage peut présenter des oscillations périodiques. Elles sont associées aux interactions entre deux couches cisaillées, se faisant face avec une vorticité opposée. Au premier ordre, la fréquence de ces oscillations dépend de la distance séparant les deux couches de mélange ; par conséquent, deux fréquences différentes peuvent être trouvées lorsque le corps a un rapport d'aspect différent de 1. Ces modes globaux oscillants semblent s'atténuer à mesure que le nombre de Reynolds et la complexité géométrique du corps augmentent. Le second type de mouvement cohérent est associé au développement d'instabilités stationnaires. Elles sont reliées aux brisures de symétrie observées en régime laminaire et leur domaine d'apparence est définit à partir de considérations géométriques dans le cas de corps parallélépipédiques avec effet de sol. Ces instabilités génèrent de fortes asymétries dans la topologie instantanée du sillage et notamment peuvent produire des écoulements bistables avec un temps caractéristique supérieur à 100H/U. L'étude de ces phénomènes, associée à des analyses de sensibilité à de petites perturbations, montre que la diminution des asymétries dans le sillage instantané est une stratégie intéressante de réduction de traînée. En particulier, il est montré que les gradients de pression à échelles locale et globale sur les cotés du corps sont sources de structures tourbillonnaires longitudinales qui pénalisent la traînée. Les dépendances quadratiques entre la traînée et les efforts transverses obtenues rappellent les mécanismes de traînée induite bien connus en aéronautique. Ainsi, comme elles sont souvent attribuées à d'importantes asymétries du sillage, les instabilités stationnaires sont identifiées comme des sources importantes de traînée. Par contre, la partie de la traînée associée aux mouvements périodiques du sillage semble négligeable, surtout pour les géométries complexes à grands nombres de Reynolds
An experimental study of the turbulent wake past different geometries is performed by increasing the complexity from axisymmetric bodies to road vehicles. Whatever the geometry is, two kinds of coherent wake motions are likely to be observed. First, at timescales of the order of 5D/U, D and U being the characteristic size and velocity of the flow respectively, the wake may generate periodic oscillations. These coherent motions are usually associated with the interaction of two facing shear layers of opposite vorticity. As the corresponding frequencies rely at first order on the distance between the shear layers, two distinct frequencies are reported when the afterbody has a cross-flow aspect ratio different than 1. These unsteady global modes seem to weaken when the Reynolds number and the complexity of the geometry increase. The second type of coherent motions corresponds to the development of stationary cross-flow instabilities. They are linked to the symmetry breaking modes observed in laminar regimes and their domains of appearance are defined from geometry considerations in the cases of parallelepiped bodies in ground proximity. These instabilities are responsible for strong asymmetries in the instantaneous flow and may generate bistable dynamics with a characteristic time scale of the order of 1000D/U. The study of these phenomena, combined with sensitivity analyses to small perturbations, places the diminution of the cross-flow asymmetries of the instantaneous wake as a relevant strategy for drag reduction. In particular, it is found that both local and global pressure gradients on the sides of the body are source of streamwise vortices increasing the drag. Parabolic dependences between the drag and the cross-flow forces are reported suggesting similarities with the mechanisms of induced drag that are well-known in aeronautics. Consequently, as they often generate significant wake asymmetries, the development of the cross-flow instabilities is identified as a drag contributor. On the contrary, the part of the drag related to the periodic global modes seems to be negligible especially for complex geometries at high Reynolds number

Abstract:
This thesis aims at investigating the behaviour of airlines in recently liberalised markets, by making use of the Brazilian air transportation as a case study. In order to accomplish this objective, the following three essays were developed: a study of low cost carrier entry behaviour, an analysis of the pricing behaviour of the major incumbents in the industry, and, finally, an assessment of airline conduct in the most important market in the country. All essays contain empirical investigation performed by making use of data supplied by Brazil’s Department of Civil Aviation, DAC. In the first essay, the entry of Gol Airlines on several Brazilian domestic routes, in 2001 and 2002, is analysed in order to draw inference on the competition between a discounter in rapid expansion and the full-service carriers. A route-choice model is estimated by making use of a flexible post-entry equilibrium profits equation and accounting for endogeneity of the main variables. The second essay aims at empirically investigating the pricing behaviour of the legacy carriers in Brazil, with special focus on reactions to the entry of Gol, in 2001. A study of localised competitive advantage regarding the determinants of pricing power is performed along with the analysis of the pattern of price reactions by the incumbents. A single econometric framework is designed and estimated with panel data controlling for city-specific effects. And finally, the third essay aims at assessing the impacts of economic liberalisation on the route Rio de Janeiro - São Paulo. By making use of both a two-stages budgeting representation of the demand system, and a competition model with product heterogeneity among rivals, and based on the framework of the New Empirical Industrial Organisation, it was possible to examine the existence of a structural change on airlines’ conduct parameters due to the regulatory reform.

Four wheel steering (4WS) is a concept proven to be beneficial in low speed applications requiring large steering angles, which is the case in city traffic or parking. By steering the rear wheels in the opposite direction to the front ones, maneuverability can be improved. However, a conflict is encountered at high speeds for all the steering strategies developed. If sharper response is achieved, this is at the expense of undesirably large vehicle sideslip angles. On the other hand, small vehicle sideslip angles are associated with heavy understeering behavior. It is not possible to improve both simultaneously in case of two-axle 4WS vehicles. The object of this study is the simulation of various steering configurations for multi-axle vehicles in an attempt to find a means of solving the problem of 4WS and to determine the best steering strategy. In addition to two-axle vehicles which have been extensively studied in literature, three- and four-axle vehicles are taken into consideration. By extending the strategies used for 4WS two-axle vehicles, new strategies are established for three and four-axle vehicles. An integrated non-linear ride and handling model in Matlab &
Simulink environment considering sprung and unsprung mass motions, wheel and tire dynamics, is used for simulations. It is shown by case studies that, with the application of the derived strategies for three and fouraxle vehicles, lateral acceleration and yaw velocity responses can be improved without degrading vehicle sideslip angle.

What if an open-source software showed what is the total cost of ownership of consumer goods, including emissions over time? Consumers' decision making is often price sensitive. An assessment of twelve mobility units' classes 1 to 5 at market price, their operation expenses, resale prices, and emissions show the real cost for the final consumer. Light-duty vehicles from the world's largest vehicle manufacturers: Toyota, Volkswagen, Honda, Hyundai, Chevrolet, Nissan, and tiny Tesla, from three continents are compared. Gasoline, hybrid, electric, and hydrogen-fueled powertrains performance over 12 years demonstrate how non-fossil fueled units offset their higher upfront price compared to their gasoline counterparts in 6 years. A micromobility option, a bicycle, is graphed against engine units. The Paris Agreement signed by 175 countries suggests a carbon tax which is levied in 29 countries. Such tax is forecasted in the non-signee of the Agreement, and number two highest polluter in the world, the United States. Three scenarios were calculated: at zero, fifteen and forty USD per Metric ton oil equivalent, as a path for massive production to account for environmental externalities. Life Cycle Analysis, Circular Economy and Smart Capitalism are articulated as solutions aiming to NetZero transportation targeting the segment responsible for the most GHG emissions in the industry, mid-sized cars. Collaboration and inclusive negotiation informed by consistent information are presented as means to lessen the gender gap and unite decision-makers to reach the Sustainability Development Goals. A systems-level approach is proposed in the form of private-public partnerships and global data sharing to scale and implement existing technologies. Cleaning the power grid by producing and storing renewable energy, implementing carbon capture, usage, and storage, and producing green hydrogen from electrolysis are pointed out as central global strategies to stop Climate Change.

Abstract:
Yongjue Yuanxian (1578-1657) was a Confucian scholar, an eminent 17th-century Buddhist Master, and a prolific writer who re-established the reputation of the Caodong Buddhism. This study investigates Yuanxian's life and his works: the Shou ta ming (Inscription of the Longevity Stupa), the Yiyan (Nonsense Uttered in Dreams), the Jie ni nü (To Refrain from Drowning Female Infants), and the Jianzhou hongshi lu (Record of Propagating Buddhism in Jianzhou). This research unfolds Yuanxian's Confucian and Buddhist backgrounds as well as his impact through his writings on both the mundane and super-mundane worlds. The Shou ta ming gives us clues regarding Yuanxian's natural inclination and life. The study of Yiyan investigates Yuanxian's philosophy, his position towards the harmonizing the Three Teachings, and his approach towards the challenges of 17th-century Chan Buddhism. The Jie ni nü provides us with Yuanxian's engagement in Fujian society, the social phenomena among the commoners, and their unconventional Buddhist concepts. His Jianzhou hongshi lu reveals eminent local Chan and Confucian masters, how the Chan teachings enhanced the Confucian scholars' demeanor, and the influence of the Chan masters of the Jianzhou area that extended well beyond that local region. Yuanxian devoted his literary talents as a reviver and fearless defender to uphold the supremacy of Buddhism. He vigorously pointed out the deficiencies of Confucianism and Daoism and expressed distinctive insight towards the popular trend of the Three Teachings syncretism. His life manifested the ideal of actualizing the functions of the super-mundane world while engaging simultaneously in society.

Abstract:
L'autonomie moyenne des voitures électriques commercialisées actuellement reste limitée par rapport aux véhicules thermiques. Pour pallier ce problème, la capacité de la batterie peut être augmentée ou bien la charge peut être facilitée en réduisant le temps de charge et ceci en augmentant la puissance de charge.L'infrastructure de charge rapide de type DC étant encore limitée, un progrès considérable consiste à embarquer le chargeur dans le véhicule en réutilisant tout, ou une partie de l'électronique de puissance déjà disponible pour propulser le véhicule. Le chargeur est alors nommé chargeur intégré.Au cours des dernières années, plusieurs chargeurs intégrés ont été proposés, mais peu d'entre eux ont été industrialisés vue qu'ils présentent des inconvénients que l'on cherchera à surmonter ou réduire.Dans le cadre de cette thèse notre objectif principal est donc de concevoir une nouvelle topologie de convertisseur permettant la charge de la batterie à moindre coût.Plusieurs idées permettant l'innovation sont proposées et une solution répondant au mieux au cahier de charges est retenue. Cette topologie est étudiée en détails (contrôle, dimensionnement, harmoniques, CEM, etc.). Finalement un prototype est réalisé pour valider le concept proposé
To date, the range autonomy of most electric vehicles is still lower than conventional fuel based vehicles and charging times are significantly longer. To overcome this problem, battery capacity could be increased but more importantly high power fast charging should be accessible everywhere.The widespread deployment of public DC fast charging stations is still difficult to achieve. So, in order to have a better spreading of the charge spots and a better coverage, it is also necessary for the vehicle to be charged from an on-board charger that could be plugged into three-phase AC power outlets.Furthermore, because the battery is charged only when the car is parked -except for regeneration at braking-, using the on-board traction system components to form an integrated charging device is possible. This kind of topology is called an integrated charger which allows designing a charger small enough to be embedded in a vehicle at an affordable cost.Several non-isolated on-board integrated charging topologies are proposed in this thesis and the one that best meets some predefined specifications is selected. This topology is studied in details and validated by simulation software. A laboratory prototype is also built to verify the performance of this multi-purpose traction/charger converter

Full text
Abstract:
The wall interference effects present on three-dimensional models during wind tunnel testing are difficult to correct using post-test model data correction methods. Further, at transonic speeds, with the use of ventilated test sections these corrections become complex to apply and inaccurate. The high quality of wind tunnel testing that is required today means that such methods are no longer satisfactory. The flexible walled wind tunnel has in recent years shown its ability to obtain two-dimensional aerofoil data free from the effects of wall boundary restraint. This work at Southampton was aimed at extending the use of the two-dimensional Transonic Self-Streaming Wind Tunnel to the relief of wall interference effects on three-dimensional models. The compromise of using only two-wall single curvature movement avoids the problems that are inherent with the additional complexity of fully three-dimensional adaptive tunnels. A method of assessing the wall-induced interference velocity components from tunnel boundary pressure data, without reference to the model, has been developed and validated against other wall interference assessment methods. The algorithm, suitable for use in adaptive tunnels, is used with a wall movement influence coefficient method of wall contour prediction resulting in the apparent removal of wall interference effects along a streamlining target line. The residual wall interference velocity components calculated to be present after streamlining on two half-wing models are significantly lower than their straight test section values. Providing the model span is not too large in comparison with the breadth of the test section, the spanwise interference velocity component is negligible. A calibrated force-balance wing-body model has been used to demonstrate the first successful streamlining around a three-dimensional model in the Transonic Self-Streamlining Wind Tunnel. The measured model force data obtained with streamlined walls compares favourably with that derived using a standard post-test model data correction method.

Abstract:
Recent trends in the energy sector have provided opportunities in the research of alternative energy sources and optimization of systems that harness these energy sources. With the rising cost of fossil fuel and rising concern about detrimental effects that fossil fuel consumption has on the environment, electric vehicles are becoming more prevalent. A study put out in 2009 gives a prediction that in the year 2025, 20% of new vehicles will be PHEVs. As energy providers become more concerned about a growing population and diminishing energy source, they are looking into alternative energy sources such as wind and solar power. Much of this is done on a large scale with vast amounts of land used for solar or wind farms to provide energy to the grid. However, as population grows, requirements of the physical components of a power transmission system will become more demanding and the need for remote micro-grids will become more prevalent. Micro-grids are essentially smaller subsystems of a distribution system that provide power to a confined group of loads, or households. Using the idea of micro grid technology, a solar charging station can be used as a source to provide energy for the immediate surroundings, or also to electric vehicles that are demanding energy from the panels. Solar charging stations are becoming very popular, however the need for improvement and optimization of these systems is needed. This thesis will present a method for redesigning the overall architecture of the controls and power electronics of typical carports so that efficiency, reliability and modularity are achieved. Specifically, a typical carport, as seen commonly today, has been built on the University of Central Florida campus in Orlando. This carport was designed in such a way that shifting from conventional charging methods is made easy while preserving the fundamental requirements of a practical solar carport.

This work aims to quantify the impact in the steady state operation of a distribution system when electric vehicles are connected. It is worth noting that the connection of them may cause significant changes in the voltage profile, in the degree of voltage unbalance and in the electrical losses of the system. In order to make this analysis, a three-phase power flow program was developed in MATLAB language. This program is based on the Ladder Iterative Technique and it contains models of overhead distribution lines, underground distribution lines, spot loads, distributed loads connected in wye and delta, step voltage regulators, capacitor banks, three-phase transformers and the model of an electric vehicle. This model allows simulation of a real electric vehicle of model Tesla Roadster, produced by Tesla Motors. The test system used in all simulations was the IEEE 13 bus. Moreover, the methodology consisted in simulate the system with the voltage regulator and without the voltage regulator under heavy load and light load conditions. The electric vehicle was connected to a specific systemâs bus and it were considered that it could work as a load or as a distributed generator with or without positive sequence voltage control. Constants configurations of the electric vehicles were considered for the heavy load and light load cases. The results of the simulations reveal there was voltage violation due to the connection of electric vehicles acting as loads in the test system under heavy load conditions without voltage regulator. When they operate as generators, they can maintain the voltage unbalance under the allowed 2%, turning the systemâs voltages more balanced. There were significant reductions when the electric vehicles acted as a load (71.1%) and as generator (77.5%) on the total real power losses when the system operated with voltage regulator on the substation and the electric vehicles operated with positive sequence voltage control (specified at 1,0 pu).
Este trabalho tem o objetivo de quantificar o impacto da conexÃo de veÃculos elÃtricos na operaÃÃo em regime permanente de um sistema de distribuiÃÃo. à visto que a conexÃo dos mesmos pode causar mudanÃas significativas no perfil de tensÃes, no grau de desequilÃbrio de tensÃo e nas perdas elÃtricas do sistema. Para realizar essa anÃlise, desenvolveu-se um programa de fluxo de potÃncia trifÃsico na linguagem MATLAB. O programa à baseado na tÃcnica iterativa de escada. Foram implementados nesse programa modelos de linhas de distribuiÃÃo aÃreas e subterrÃneas, modelos de cargas concentradas e distribuÃdas conectadas em delta e em estrela, modelos de reguladores de tensÃo, modelos de banco de capacitores, modelo de transformadores trifÃsicos e o modelo do veÃculo elÃtrico. Esse modelo permite simular o veÃculo elÃtrico Tesla Roadster da Tesla Motors. O sistema teste utilizado em todas as simulaÃÃes foi o sistema IEEE 13 barras. A metodologia utilizada consistiu em simular o sistema sem regulador de tensÃo e com o regulador de tensÃo, em carga pesada e em carga leve. O veÃculo elÃtrico foi conectado a uma barra do sistema e considerou-se que o mesmo podia funcionar como carga ou gerador distribuÃdo sem e com controle de tensÃo de sequÃncia positiva no ponto de conexÃo. Adotou-se disposiÃÃes constantes de veÃculos elÃtricos para os casos de carga pesada e carga leve. Os resultados das simulaÃÃes revelam que houve violaÃÃo de tensÃo devido à inserÃÃo de veÃculos elÃtricos atuando como carga no sistema teste em carga pesada sem regulador de tensÃo. Jà quando operam como gerador, os veÃculos elÃtricos diminuem o grau de desequilÃbrio em mÃdia, podendo mantÃ-lo abaixo do limite permitido de 2 %, tornando assim as tensÃes das barras trifÃsicas do sistema mais equilibradas. Houve reduÃÃes significativas quando os veÃculos elÃtricos atuaram como carga (71,1 %) e como gerador (77,5 %) na perda de potÃncia ativa total do sistema quando o sistema operou com regulador de tensÃo na subestaÃÃo e os veÃculos elÃtricos operaram com controle de tensÃo de sequÃncia positiva (especificada em 1,0 pu).

Abstract:
The space environment presents various challenges when designing systems and selecting materials for applications beyond Earth’s atmosphere. For mission success, these challenges must be considered. One of the detrimental aspects of the space en- vironment is Atomic Oxygen, AO. Only present in harmful quantities in Lower Earth Orbit, LEO, AO causes significant damage to materials by breaking molecular bonds. California Polytechnic State University’s, Cal Poly’s, space environments laboratory features an apparatus capable of simulating this environment. Very thin or short samples were tested to observe the mass loss due to erosion of the sample material. Recent modifications to the system allow it to expose surfaces of three dimensional objects to AO rather than only those two dimensional objects. Simulating this effect on taller samples makes available the opportunity to test coupons that are then used in additional testing to measure the effect of that erosion on other properties. Challenges in adapting the AO system are explored and addressed, as well as some possible use cases for future work. As a use case, bending moment specimens were exposed to AO prior to testing in four point bending. Multiple regression models were constructed to determine variables contributing to slope changes between specimen pairs’ linear-elastic regions of force-displacement graphs. Results show that AO exposed specimens had significantly gentler slopes in the linear elastic region of the force-displacement curve, meaning that AO exposure reduced structural rigidity of the coupons.

Abstract:
Chapter 1. This chapter aims to find the effects of financial point of sales incentives on the sales of electric vehicles across the Canadian provinces from September 2012 to December 2016. The findings of my study indicate that purchase incentives cause the sales of new electric vehicles to increase by 8 percent on average due to a $1000 increase in incentives. I find that 47% of electric vehicle sales across the rebating provinces (Ontario, Quebec, and British Columbia) are attributed to the purchase incentives. Results of my counter-factual simulations imply that the cost of eliminating one tonne of carbon emissions across the provinces that offer incentives over the years of my study is, on average, $216/tonne CO2. Chapter 2. In light of the rapid increase in Canadian gasoline prices from 2000 to 2010, this chapter focuses on the relationship between gasoline price and demand for vehicle fuel efficiency across the Canadian forward sortation areas (FSA) over this period. I find that consumers respond to variations in gasoline price when deciding the fuel efficiency of their new vehicle; increases in gasoline price result in shifts in demand for more fuel-efficient vehicles and therefore improve the average fuel efficiency of the new vehicle fleet. I find that the elasticity of fuel economy with respect to gasoline price for new vehicles sold across the Canadian forward sortation areas (FSA) from 2000 to 2010 is -0.06 to -0.16. Results of further analyses imply that consumer are more responsive to rising and constant gasoline prices than falling prices and that urban residents are slightly more responsive to variations in gasoline price compared to residents of suburb regions. Chapter 3. This chapter investigates the effect of the carbon tax policy implemented by the Canadian Province of British Columbia on households’ new vehicle purchase decisions. I dis-aggregate the effects of gasoline price into two effects: the carbon tax and carbon tax-exclusive gasoline price. These effects are both measured along the extensive margin of replacing a fuel inefficient vehicle with a fuel-efficient vehicle. The results indicate that there is a significant negative relationship between both effects and fuel efficiency substitutions. However, vehicle fuel economy is more sensitive to changes in the carbon tax than to equivalent changes in the carbon tax-exclusive gasoline price. I find that the elasticity of fleet fuel economy with respect to the carbon tax ranges from -0.22 to -0.26 whereas this elasticity changes between -0.1 and -0.15 with respect to gasoline price (net of the carbon tax). I obtain consistent results when estimating the effect of both factors on fleet fuel economy conditional on fleet composition, indicating that almost all vehicle segments respond more strongly to changes in the carbon tax component of gasoline price than other components. Results also imply that, among all segments, the fuel consumption of compact sport utility vehicles (SUVs), minivans, and luxury high-end cars respond the most to the carbon tax.

Abstract:
The core premise of the thesis is that our global environmental and social crises are of our own making and can only be transformed by us. Therefore it is imperative that humanity finds ways of protecting and sustaining the natural environment for our collective survival. This necessarily depends on human beings� ability to co-exist in harmony with other humans and species and to feel connected to and protect nature. This thesis examines three spiritual or wisdom traditions � Aboriginal spiritualities, the Goddess movement and Tibetan Buddhism, as they relate to Arne Naess�s concept of the �ecological self.� The ecological self is a psychological construct that suggests that human beings can evolve from a narrow egocentric way of being and relating to others, to one that is more open, inclusive of the �other� and where one sees all lives as important. One is ultimately able to embrace the whole earth community, so that nothing is excluded as �other�. This process of increasingly �wide identification� Naess defined to be the process of the development of the ecological self. There is much written about spirituality and the environment but little relevant research that specifically examines spiritual traditions as they relate to the ecological self. The insights of transpersonal psychology elucidate the maturation from ego consciousness to eco-consciousness � a process of progressively inclusive identification with �others�, including the environment. However, transpersonal psychology does not directly �converse� with Naess�s construct of an ecological self. This thesis examines the nexus between Arne Naess�s ecological self, transpersonal psychology and the three spiritual traditions. �Aboriginal spiritualities� refers to Australian Aboriginal spiritualities, unless other wise stated. The literature review covers relevant background to the ecological self in relation to Western science and thought; this includes constructions of self and �other� and story. Literature reviews of the three traditions informed in-depth interviews with five research participants who practise or identify with their particular spiritual tradition. I believe this research will enable the reader to gain an overview of the ecological wisdom of these three spiritual traditions, grounded in the lived experience of practitioners who embody these traditions. Each wisdom tradition has a long history of imparting psychological, social and ecological insights and understandings that are profoundly helpful and relevant to the current period of ecological crisis. The interviews are analysed under the broad conceptual themes of ecology, compassion and story. These traditions will be shown to encourage compassion, connectedness, interdependency and impart ecological wisdom - all vital to the realisation of the �ecological self�. Story, lifelong learning and the ecoeducational model are used as frameworks for examining the educational potential of the spiritual traditions involved. A choice must be made: will we continue to base our knowledges on Western science or will we examine alternate constructions of reality, such as those of the three spiritual traditions examined in this thesis? The three spiritual traditions provide a compassionate and non-violent view of human consciousness with the potential to transform into an ecologically sensitive creative force. This thesis argues that great wisdom is held by these three wisdom traditions in the context of education for sustainability. This thesis examines this context.

Abstract:
The development of modern sailing boats has been based almost entirely on the cooperative efforts of enthusiastic skippers, designers and sail-makers, with very little contribution from scientists and technologists and using just basic scientific principles. In recent times, urgent and strong requests for improved performance, mostly for racing yachts, have guided the interest and the attention of the scientific community in the optimisation of sail performance and design approach. Sailing performance depends on the sailboat velocity, aerodynamic and hydrodynamic characteristics. This thesis focuses on the importance of the quantitative evaluation of the sail loads and how this contributes to the improvement of the performance of a sailboat through the development of a system for aiding sail design and assisting mast design. The objective of this study is to provide an integrated design system, which supplies analysis method and design features via a user-friendly graphical interface of a single-sail configuration. The major achievement is the development of an integrating numerical method, which evaluates loads and their distribution and the consequent deformed sail-shape. It improves sail performance analyses and design of new sails. Summarising, the major achievements are: • efficacy of accurate performance analysis for each sail, for any given shape over all the possible sailing courses; • critical investigation of the sail behaviour in the above-mentioned cases; improved approach to an integrated sail design; improvements in mast design from the structural and aerodynamic point of view; limited design costs, in terms of time consumed and computational power employed; efficacy of the visualisation of novel designed sail and predicted performance, which reduces the number of possible design flaws. hi conclusion, the integrated sail analysis and design system presented has important margins of improvements and diversification: extensions to non-homogeneous and anisotropic sailcloth, to two-sail configuration, windsurfs and integration of the mast.

Abstract:
The main objective of this document is to explore the life and spiritual convictions of composer Peter Lieberson, and the creation of his Piano Concerto. Lieberson is a sought after composer who has won many awards and commissions. His works have been premiered and performed by some of the best musical artists of the late twentieth- and early twenty-first-century, such as Peter Serkin, Emmanuel Ax, Yo-Yo Ma, and Pierre Boulez. This study is divided into six chapters. After the Introduction, a biographical summary of Peter Lieberson's life, his spiritual beliefs and compositional style is presented. Chapter II contains background information on the Piano Concerto, along with biographical sketches of Peter Serkin, for whom the work was written, and Seiji Ozawa, music director of the Boston Symphony Orchestra and conductor of both the premier performance and Serkin's recording of the piece. Chapter III is a selective survey of the compositional techniques used in Lieberson's Concerto, in terms of the application of twelve-tone theory and the resulting octatonic, pentatonic, and whole-tone scales. Chapter IV introduces a general overview of the influence of Buddhism as a source of inspiration in the Piano Concerto. Chapter V examines aspects of performance practice issues. Chapter VI provides conclusions. The aim of this study is to further establish Peter Lieberson's stature as an important modern American composer. It is hoped that this study will encourage further research and interest in his works.

Abstract:
Context. Since its rendezvous with comet 67P/Churyumov-Gerasimenko (67P), the Rosetta spacecraft has provided invaluable information contributing to our understanding of the cometary environment. On board, the VIRTIS and ROSINA instruments can both measure gas parameters in the rarefied cometary atmosphere, the so-called coma, and provide complementary results with remote sensing and in situ measurement techniques, respectively. The data from both ROSINA and VIRTIS instruments suggest that the source regions of H2O and CO2 are not uniformly distributed over the surface of the nucleus even after accounting for the changing solar illumination of the irregularly shaped rotating nucleus. The source regions of H2O and CO2 are also relatively different from one another. Aims. The use of a combination of a formal numerical data inversion method with a fully kinetic coma model is a way to correlate and interpret the information provided by these two instruments to fully understand the volatile environment and activity of comet 67P. Methods. In this work, the nonuniformity of the outgassing activity at the surface of the nucleus is described by spherical harmonics and constrained by ROSINA-DFMS data. This activity distribution is coupled with the local illumination to describe the inner boundary conditions of a 3D direct simulation Monte-Carlo (DSMC) approach using the Adaptive Mesh Particle Simulator (AMPS) code applied to the H2O and CO2 coma of comet 67P. Results. We obtain activity distribution of H2O and CO2 showing a dominant source of H2O in the Hapi region, while more CO2 is produced in the southern hemisphere. The resulting model outputs are analyzed and compared with VIRTIS-M/-H and ROSINADFMS measurements, showing much better agreement between model and data than a simpler model assuming a uniform surface activity. The evolution of the H2O and CO2 production rates with heliocentric distance are derived accurately from the coma model showing agreement between the observations from the different instruments and ground-based observations. Conclusions. We derive the activity distributions for H2O and CO2 at the surface of the nucleus described in spherical harmonics, which we couple to the local solar illumination to constitute the boundary conditions of our coma model. The model presented reproduces the coma observations made by the ROSINA and VIRTIS instruments on board the Rosetta spacecraft showing our understanding of the physics of 67P’s coma. This model can be used for further data analyses, such as dust modeling, in a future work.

Abstract:
Cette thèse porte sur l'intégration du con-vertisseur DC-DC entre les batteries haute et basse tension (400V / 14V), avec un chargeur embarqué monophasé présent dans l'architecture du véhicule électrique. Dans cette intégration, les deux convertis-seurs sont bidirectionnels et l’isolation galvanique est nécessaire entre les trois sources d'énergie. Dans une première partie de cette étude, nous sommes focali-sés sur le développement d’un convertisseur DC-DC à trois ponts.Le convertisseur DC-DC proposé est un convertisseur bidirectionnel alimenté en courant à résonance pa-rallèle permettant de réaliser des commutations à zéro de tension sur toute la plage de puissance. Grace à la « recopie de tension », le dimensionne-ment du transformateur permet la réalisation d’unestructure beaucoup plus compacte par rapport à d’autres convertisseurs à résonance. Dans la deu-xième partie de ce travail, les caractéristiques du convertisseur sont étudiées afin d’optimiser la stra-tégie de commande et de fonctionnement. Le dé-veloppement d’un transformateur planar est réalisé en respectant les normes pour les véhicules élec-triques et pour minimiser les inductances de fuite. L’étude de la répartition de courant dans les couches connectées en parallèle est faite de façon à éviter la présence de points chauds en haute fré-quence. Le prototype et les résultats finaux sont présentés pour valider le convertisseur à 3 ponts. Après avoir analysé les résultats, quelques proposi-tions sont faites pour améliorer les résultats dans les futurs travaux
This dissertation focuses on the integration of two power electronic converters present in the electric vehicle (EV) architecture – the DC-DC con-verter interfacing the high and low voltage batteries (400V/14V) and the onboard charger (OBC). A three-port current-fed parallel resonant topology with zero voltage switching capability is developed. The con-verter allows bidirectional power flow between the three energy sources with high efficiency in both conversion modes, DC-DC and OBC while ensuring galvanic isolation.A compact three-winding planar transformer is de-signed based on EV industry requirements, empha-sizing the minimization of leakage inductances. In this design, the unequal currentsharing phenomenon between parallel-connected layers is addressed to ensure a homogeneous cur-rent distribution and eliminate the risks of thermal hotspots formation.A 7kW experimental prototype has been con-structed and tested, validating the analysis and op-eration of the proposed topology. Some sugges-tions and propositions are provided for future work aiming at efficiency improvement of the converter

Veículos elétricos são considerados a melhor alternativa aos veículos com motores de combustão interna, apresentando vantagens bastante significativas, tais como: emissão zero de poluentes, alta eficiência dos motores elétricos e baixa emissão de ruído acústico. O sistema de propulsão de um veículo elétrico consiste basicamente de uma ou mais fontes de energia, um ou mais motores, conversores de potência, componentes eletrônicos, componentes mecânicos para transmissão de torque e velocidade e rodas com pneus. Neste trabalho é proposta a modelagem de um sistema de propulsão para um veículo elétrico, que inclui o modelo dinâmico veicular para movimento longitudinal, o modelo dinâmico do motor elétrico, o modelo do conversor utilizado para acionamento do motor e o modelo do sistema de controle. Devido às características bastante adequadas para aplicação em sistemas de propulsão automotiva, o motor de indução trifásico é o selecionado para estudo. A estratégia de controle para acionamento do motor, foco deste trabalho, é o Controle Vetorial Direto Orientado pelo Fluxo do Estator, que garante alto desempenho, rápida resposta dinâmica e apresenta insensibilidade à variação de parâmetros do motor durante sua operação. São desenvolvidas novas técnicas para a reconstrução dos sinais das tensões do estator a partir de sinais de controle PWM do conversor e da tensão DC que alimenta o inversor e estimativa da amplitude e posição angular do vetor espacial do fluxo do estator, primordial para a estratégia de controle adotada. A modelagem é toda desenvolvida utilizando o software PSIM e os resultados de simulação são apresentados.
Electric vehicles are the best alternative to internal combustion engines vehicles, presenting significant advantages such as: zero emission of pollutants, high efficiency of electric motors and low noise emission. Basically, an electric vehicle propulsion system consists of one or more energy sources, one or more engines, power converters, electronic components, mechanical components for torque and speed transmission, and wheels with tires. This work proposes the modeling of a propulsion system for an electric vehicle, which includes the dynamic vehicle model for longitudinal movement, the dynamic model of the electric motor, the model of the converter used as motor driver and the model of the control system. Due to very suitable characteristics for application in automotive propulsion systems, three-phase induction motor is chosen for this study. Focus of this work, Direct Stator-Flux-Oriented Vector Control is the control strategy for the motor drive, which guarantees high performance, fast dynamic response and insensitivity due motor parameters variation during its operation. New techniques are developed for the reconstruction of the stator voltages signals from the PWM control signals of the converter and the DC voltage that feeds the inverter and the estimation of the amplitude and angular position of the spatial vector of the stator flux, primordial for the adopted control strategy. Modeling is developed using PSIM software and simulation results are presented.

With the annual average temperature gradually increasing, the slogan“Energy Efficiency and Carbon Reduction 〞is also shouted in our ears. Although the traditional gasoline-fueled motorcycles, market is still the dominant market in Taiwan for its convenience, GOGORO, the i-PHONE in motorcycle industry, breaks in in full fury. Due to the introduction of High-tech, cellphones have been applied to combine with electric motorcycles in recent years. In addition, each local governments are all willing to provide subsidies to carry out this development for the purpose of promoting the environmental consciousness. Therefore, GOGORO has gained more and more market share. The traditional motorcycle industry-Sanyang Motor is about to release its own electric motorcycle in the near future. The prospects of electric motors are expecting. Three-wheel motorbikes are more stable than two-wheel ones based on mechanic. Undoubtedly, costs will increase and there will be more or less different aspects between them, which we need to adapt to. Such as the size of the motorcycle becomes bigger, but roads do not change; neither will the public qualification be improved as high as it in Japan or German. Nevertheless, there are still many challenges we require to overcome; take Taiwan for instance, without taking legislation into account. Batteries and charging devices appear to be the biggest problem in the electric motorcycle industry; actually, we realize the major problem is its related system. Government just shout the slogan in the electric motorcycle industry for a long time; thus, there are still only a minor people using electric motorcycle. In recent years, electric vehicles produced by Tesla Incorporation after occupied front, page News. Gradually, we can find more and more electric vehicle charging stations; meanwhile, the electric vehicle industry gets thriving. The growth of two-wheel motorcycles and the latest Tesla electric vehicles becomes anticipating. Electric tricycles belong the niche market and achieve some accomplishments in short-distance freight industry owing to its stability beyond two-wheel car’s and its price is cheaper than electric vehicles’. This thesis is going to discuss how to solve the problems about the driving of electric tricycles on flat roads as well as how to adjust legislation.

Abstract The thesis based on the Three Treasures, or Buddha, Dharma, Sangha, as recorded in the “Han Dynasty Translation of the Northern Sect’s Great Treasury of Sutras”, and attempts to manifest the essence of the Three Treasures through a sand art on a lamp platform. The thesis can be divided into four chapters. Chapter I, “The Introduction”, contains background, motivation and objectives behind the research and creation, as well as scope and method of research and creation. Chapter II, “The Origin of Buddha image in India”, expounds on the origin of Buddha Image in India, traced from carvings on the ancient Sanchi Stupa built by King Ashoka, which records Sakyamuni Buddha’s life story and Buddhist art and culture. The value and status of such ancient relics confirms that Sakyamuni Buddha was a living person rather than a mystic legend. The Sanchi Stupa is the oldest and best preserved of all Buddhist relics, offering a gateway to the Buddhist doctrines, aside from the profuse and diverse facets of ancient Indian Buddhist art. The carvings on the Stupa entails stories of Sakyamuni Buddha himself, adopting all sorts of symbols to represent the Buddha in what is generally considered to be the non-Buddha image period in Buddhist art theory. With the passing of time and evolving of eras, anthropomorphic representations of the Buddha figure started to emerge from first century BC in ancient India’s two main noted centers: Gandhara and Mathura. Gandhara in India’s northwestern region was under huge artistic influence of western Greek culture, with all kinds of symbols in Buddhist carvings and scrolls replaced by the concept of Buddha images. As the trend for sculptured anthropomorphic representation of Buddhist images started to gather momentum in Gandhara from the end of the first century AD onwards, Mathura forsook the non-image renouncement, and Mathura-styled Buddha figures could here to flourish; the Indian indigenous Buddhist art was thus born. Buddhist art is embedded in all forms and contents, such as sculpture, architecture, drawings and craft. Sculpture and anthropomorphic Buddha painting are the concrete manifestation of commiserating Buddha. Painting Buddha images is a way to cultivate the mind, dispossess distractions, stretch the attention span, and engage the heart. This thesis discourse employs some modern-day instruments – lighting, glass panels, and cameras – to paint a picture with coastal sand from nature, to manifest the essence of Three Treasures by way of the tablet method. Chapter III the meaning of Three Treasures and sand painting creating based on the significance of the Three Treasures Buddha, Dharma, Sangha, as recorded in the “Han Dynasty Translation of the Northern Sect’s Great Treasury of Sutras”. The five-stages of Sakyamuni Buddha’s life -- birth, becoming a monk, achieving enlightenment, first turning the Dharma wheel, and reaching nirvana -- are in place to demonstrate the Buddhist treasures. The Four Noble Truths are Buddha’s basic teachings. Venerable Ananda, the one that remembered most of the discourses by the Buddha; Master Xuanzang, the one that journeyed west to obtain the sutras, and Taiwan’s Master Baisheng are all representatives of the Sangha Treasure. Chapter IV, “Conclusions”, is to integrate all aforementioned aspects and further propose future research directions that have not been explored in the thesis. Keywords : the Three Treasures of Buddhism, Sanchi stupa, The Buddha image, Sand art.

Abstract:   The purpose of this study is to delve into the experience of psychologists with buddhism background in the consulting profession. The essence can be presented and interpreted more deeper meaning behind the essence of experience. Researchers must find common traits in different cases and summarize the conceptual structure by defining the respondents to explain the findings.   Based on the viewpoint of narrative research, under the framework of the pattern model, combined with semi-structured in-depth interviews to collect data, we found that the most important confusion experience of the research participants came from the impact of the issue of sexual orientation on the Dharma viewpoint. (2) Confusion of the theory of consultation and belief values. (3) Confusion of spiritual events. (4) Confusion of ethical issues. The response method is: (1) The understanding of the doctrine is more thorough. (2) The choice of ethical values. (3) Integrating the content and methods of religious significance into the methods of consultation. (4) Support from institutions and supervisors. And after the experience of adjusting beliefs and consultations, the influence and help on their professional development and beliefs are as follows: (1) The motivation for more continuous learning. (2) A new perspective on the interpretation of doctrine (3) The Dharma viewpoints and methods are actually used in the profession.   Based on the above results, this study is to offer directions and suggestions of follow-up puts research for psychologists with buddhism background.

Abstract:
Two and three-wheeled vehicles are being used in increasing numbers in many emerging countries. The dynamics of such vehicles are very different from those of cars and other means of transportation. This thesis deals with a study of the dynamics of a motorcycle and an extensively used three-wheeled vehicle, called an “auto-rickshaw” in India. The commercially available multi-body dynamics (MBD) software, ADAMS, is used to model both the vehicles and simulations are performed to obtain insight into their dynamics. In the first part of the thesis, a study of the two wheeler dynamics is presented. A fairly detailed model of a light motorcycle with all the main sub-systems, such as the frame, front fork, shock absorbers , power train, brakes, front and rear wheel including tire slips and the rider is created in ADAMS-Motorcycle. The simulation results dealing with steering torques and angles for steady turns on a circular path are presented. From the simulation results and analytical models, it is shown that for path radius much greater than motorcycle wheel base, the steering torque and angle can be described by only two functions for each of the two variables. The first function is related to the lateral acceleration and can be determined numerically and the second function, in terms of the inverse of the path radius, is derived as an analytical approximation. Various tire and geometric parameters are varied in the ADAMS simulations and it is clearly shown that steady circular motion of a motorcycle can be reasonably approximated by only two curves–one for steering torque and one for steering angle. In the second part of the thesis, a stability analysis of the three-wheeled “autorickshaw” is presented. The steering instability is one of the major problems of the “auto-rickshaw” and this is studied using a MBD model created in ADAMS-CAR .In an Initial model the frame ,steering column and rear-forks (trailing arms) are assumed to be rigid. A linear eigenvalue analysis, at different speeds, reveals a predominantly steering oscillation, called a “wobble” mode, with a frequency in the range of 5 to 6Hz. The analysis results show that the damping of this mode is small but positive up to the maximum speed(14m/s) of the three-wheeled vehicle. Experiments performed on the three-wheeled vehicle show that the mode is unstable at speeds below 8.33m/s and thus the experimental results do not agree with the model. Next, this wobble instability is studied with an analytical model, similar to the model proposed for wheel shimmy problem in aircrafts. The results of this model show that the wobble is stable at low speeds regardless of the magnitude of torsional stiffness of steering column. This is also not matching with the experimental result. A more refined MBD model with flexibility incorporated in the frame, steering column and the trailing arm is constructed. Simulation results with the refined model show three modes of steering oscillations. Two of these are found to be well damped and the third is found to be lightly damped with negative damping at low speeds, and the results of the model with the flexibility is shown to be matching reasonably well with the experimental results. Detailed simulations with flexibility of each body incorporated, one at a time, show that the flexibility in the steering column is the main contributor of the steering instability and the instability is similar to the wheel shimmy problem in aircrafts. Finally, studies of modal interaction on steering instabilities and parametric studies with payload and trail are presented.

Buddhism is faced with challenges and opportunities in the trend of globalization. This thesis will discuss how Humanistic Buddhism break through barriers of ethnicity and religion through Physical Education, and create values and perspective of Humanistic Buddhism. The purpose of this study begins from the ideology of the Venerable Master Hsing Yun’s propagation of Dharma through Physical Education, focusing on the Three Acts of Goodness, in order to examine the ideology and realization of sports as a way of propagation in Fo Guang Shan. This paper will also analyze the sports team under the Fo Guang Shan Sport Association to determine the success of the implementation of the Three Acts of Goodness, in order to see the highlights behind this form of Dharma propagation. Except literature review, this paper will also use Polanyi’s tacit knowing theory to explain the impact the Three Acts of Goodness has on the athletes. The second chapter of this thesis is an examination of the philosophy behind Venerable Master Hsing Yun’s effort in propagating Dharma through sports, placing the importance on cultivating human minds through the Three Acts of Goodness. The relationship between Buddhism and sports is a learning to balance the body and mind. In order to foster talents that uphold the Three acts of Goodness, the Five Precepts and Ten Wholesome Acts is taught as the foundation for ethical values, along with the Eight Ways of Being Healthy and the Eight Ways of Curing the Mind. When the ideology of the Three Acts of Goodness is conferred and realized, it will be part of a person’s consciousness, and the seed of the Three Acts of Goodness will grow, as stated by Polanyi’s tacit knowing. The important features of such method of Dharma propagation is that it represent a new form of thinking for ways to propagate the Dharma, as well as expand the educative purposes of Physical Education. Through promoting the Three Acts of Goodness, it achieves the goal of growth of character, improve society, and slowly heading towards the goal of world peace. Propagating the Dharma through Physical Education is a skillful means, and a positive way to engage with the society. If the Physical Education as means of propagation could develop well, it will have positive impact upon the development of sports and society.
