<p dir="ltr">Smartphones have revolutionized personal computing by blending communication, entertainment, and productivity into one. Emerging applications demand high computational capabilities and are power-hungry. Optimizing the battery drain of mobile apps is critical to extending the battery life of mobile devices, enhancing the user experience. This involves optimizing the power consumption of all power-hungry components in modern smartphones.</p><p dir="ltr">The power draw of a mobile System on a Chip (SoC) is determined by its computational requirements and can become a bottleneck for the entire system. To understand and optimize power consumption, it is essential to accurately characterize the power of heterogeneous SoCs and study the interplay among default governors for the mobile CPU, GPU, and memory. Therefore, power modeling of mobile device components is foundational for effective energy profiling and analysis.</p><p dir="ltr">This thesis presents an understanding of the power consumption on modern smartphones and contributes to creating a display power model for Organic light-emitting diode (OLED), developing a lightweight GPU power model, and finally creating a Unified energy-aware governor for LLM.</p><p dir="ltr">First, we develop a novel piecewise OLED power model that accurately estimates the display power draw as a function of the displayed content. We present the design and implementation of two OLED power management tools: an accurate per-frame OLED display power profiler called PFOP and an enhanced Android Battery called Battery+ that help phone users to understand and manage phone display energy drain.</p><p dir="ltr">Second, we present APGPM, the first mobile GPU power modeling methodology that automatically selects an optimal set of performance monitoring counters (PMCs) that can accurately estimate the GPU power across different workloads. We implement APGPM in Android and evaluate it on two representative mobile GPUs, Qualcomm’s Adreno and ARM’s Mali, for diverse GPU workloads. Our evaluation shows that APGPM builds a GPU power model that reduces the average GPU power prediction error by almost half compared to the prior-art, utilization-frequency based smartphone GPU power model.</p><p dir="ltr">Third, we present a unified energy-aware governor designed to optimize the energy efficiency of three power hungry components, CPU, GPU, and memory, for large language model (LLM) inference on mobile devices. We show that the triplet governors used in mobile OSes such as Android can result in longer prefilling and decoding latencies compared to optimal combinations of CPU/GPU/memory frequencies under the same energy budget. Our unified energy-aware governor, LEG, is shown to significantly reduce time-to-first-token and time-per-output-token of LLM inference compared to the default governors.</p>

The office of a state lieutenant governor often fails to evoke images of power, influence, or prestige. However, in Texas the office is regarded by many as the most powerful political office in the state. The Texas lieutenant governor derives his power from several sources, including the Texas Constitution, Senate rules, statutes, and the personality of the officeholder. This work explores the role of the Texas lieutenant governor in the pre-modern period with an examination of the office’s legalistic and pre-statehood roots. Aspects explored include the backgrounds of the men who became lieutenant governor, the power the officeholders exerted during their time in office, and whether or not the office became a platform for future political success. The men who served as lieutenant governor during the first century of statehood for Texas did not have the power enjoyed by their more recent contemporaries. However, some of them laid a foundation for the future by exploiting political opportunities and amending legislative practices. As Texas grew into a modern and urban state, the power and influence of the office of lieutenant governor also grew.

Indiana University-Purdue University Indianapolis (IUPUI) / Prior studies on state legislative elections have found gubernatorial coattails playing a key role; however, they fail to examine the temporal and state-based trends of this phenomena. Using precinct level data from nine states (Alabama, Arkansas, California, Minnesota, New York, Oklahoma, Tennessee, Texas, and Wyoming), over two election cycles (2002 and 2006), I measure the importance a state’s ideological makeup, and a governor’s institutional powers has on gubernatorial coattails. Findings reaffirm the importance of coattails, and previously researched variables; however, the addition of the above measures greatly affects coattail strength, dependent on host of controlling factors.

Thesis (D. Litt. et Phil. (Biblical Studies)) / The Fertile Crescent, due to its geographical characteristics, has always been an area troubled with conflict and warfare. The men who participated in these wars, from ca 2000 BCE to 1000 BCE operated from an ethos which was governed by a system of rules, all which were conceived to be the creation of divine will, to which kings and their warriors (keymen) were subject. The cuneiform texts from Mari, Ugarit, Ebla, Amarna and others, have not only thrown light on the political, social, religious and military aspects of those turbulent times, but have also given insight into the formation of armies as well as the commanders who led those armies and the royal officials who governed cities and provinces, all appointed by the monarch in order to effect the smooth running of his kingdom. They also shed light on the formation of coalitions and alliances in order to promote peace, arrange marriages to the daughters of other ruling powers and to promote trade relations. These were no easy tasks, considering the diversity of peoples, the birth and fall of kingdoms and empires, and the ever shifting and changes of loyalties of greedy kings and their men, to attain power and conquest for themselves.. However, these texts also give glimpses of the human side of the king and the close relationships between himself and his men of authority, whilst the women of the court also played their role in some areas of the social field. The responses, of these people towards matters and events, whether they were confrontations, marriage alliances, trade ventures or hunting expeditions, occurred within an ever changing world yet, it was also a world with an ethos of ancient traditions, which did not disappear but instead remained, albeit in adapted or altered form, to be a part of their contextual reality. / Biblical Studies

Parental involvement (PI) in school governance is an international acclaimed worldwide practice and is viewed as a major topic in current educational reforms. This study investigated the management of PI programmes in public schools within the jurisdiction of Bulawayo Metropolitan Province in Zimbabwe. The Total Quality Management (TQM) framework was employed as attempts were made to bring all stakeholders on board in the pursuit of quality education. To achieve this thrust, literature on the historical developments which obtained in the United States of America, China and South Africa on the phenomenon was reviewed. Further to that, the models of PI which influenced the adoption of what has obtained in Zimbabwean public schools were cited too. In the process the legal statutes which mandated PI programmes in operation were explored in detail. Data for this study was obtained by means of a quantitative approach involving questionnaires with precoded responses from a sample of 51 education managers and 47 school governors. The major findings of the empirical investigation was that PI is juridical and the bulk of the parents want to be engaged in both formal and informal academic issues of the school business as long as such engagement is well planned and organised. This collaboration of the minds and efforts does not only enhance the management style of the education manager but also the realisation of academic excellence in schools as both parties collectively embark on a quality conscious crusade. Generally, parents in this province were found to be less meddlesome when it comes to the professional governance of the school system, thus making the bulk of schools in this region “conflict free zones”. Disturbing though was the failure by parents to be engaged in the conception of the school vision and mission statement. Finally, the engagement of parents in the management of PI programmes has been recommended in this thesis as it has been found to be genuine, transparent, human resource oriented, dialogical and accountable if citizen participation in school governance is to be envisaged within a democratic framework. Orientation workshops and seminars can be manned for this purpose if home-brewed PI models meant to enhance ownership, commitment and motivation are to be realised. In that way, a customised educational menu may be approximated. / Teacher Education / D. Ed. (Education Management)

Cette thèse porte sur la modélisation, la réduction et la commande des grands systèmes électriques.En terme de modélisation et de réduction, l’objectif principal est de développer une méthode de réduction des modèles dynamiques des systèmes électriques. Cette réduction a pour objet de répondre à une situation particulière dans laquelle toutes les données du système à réduire ne sont pas connues.En terme de commande, l’objectif est la conception de commandes robustes coordonnées pour répondre aux nouvelles contraintes des grands systèmes électriques. Ces approches doivent respecter trois niveaux de coordination et deux nouvelles contraintes. Les trois niveaux de coordination concernent la prise en compte simultanée des oscillations électromécaniques interzones et locaux, la coordination de la synthèse de régulateurs pour plusieurs alternateurs, et la coordination du réglage des paramètres (gains et constantes de temps) des régulateurs de tension (les boucles stabilisatrices PSS) avec le réglage des paramètres des régulateurs de turbine des alternateurs. Les contraintes sont liées à la stabilité et la robustesse des régulateurs proposés. / This thesis concerns modeling, reduction, and control of large-scale interconnected power systems. In modeling and reduction term, the main objective is to develop a new method to construct low-order model or dynamic equivalent of a large-scale power system. This method must be used to reduce a power system models even when information of the whole power system is not completely available. In control term, the objective is the synthesis of coordinated and robust controller for large scale power systems. These new approaches have to respect three coordinated levels and two new constraints. The Three coordinated levels concern: simultaneous damping of the electromechanical inter-area and local modes, coordinated synthesis of several alternator regulators and coordinated tuning of parameters of Standard Power Stabilizer (PSS) and speed regulators. The constraints are related to the stability and the robustness of the proposed regulators.

"This study is being made to assess the actual importance of the platform in recent gubernatorial elections in Texas. Because an intensive analysis is undertaken, the scope of this thesis has been limited in two ways. First, it is confined to the years 1946-1963 spanning the Administrations of Governors Beauford Jester, Allan Shivers, and Price Daniel. Secondly, in an attempt to compare the executives with one another, platform promises related to education, health and welfare, highways, and taxation adopted at the Democratic State Convention have been included. The method utilized to determine fulfillment of a political promise has been to compare the Governor's recommendations to the Legislature with the resulting action. In particular, an attempt has been made to (1) describe the Democratic primary election, with special reference to the issues raised; (2) to discuss the Democratic State Convention with a listing of the planks mentioned above; and (3) to analyze proposals in the Governor's State of the State Messages and special messages and to compare them with the resulting legislative action." -- leaf 1.
