Description
Increasing computational demands in data centers require facilities to operate at higher ambient temperatures and at higher power densities. Conventionally, data centers are cooled with electrically-driven vapor-compressor equipment. This paper proposes an alternative data center cooling architecture that is heat-driven. The source is heat produced by the computer equipment. This dissertation details experiments investigating the quantity and quality of heat that can be captured from a liquid-cooled microprocessor on a computer server blade from a data center. The experiments involve four liquid-cooling setups and associated heat-extraction, including a radical approach using mineral oil. The trials examine the feasibility of using the thermal energy from a CPU to drive a cooling process. Uniquely, the investigation establishes an interesting and useful relationship simultaneously among CPU temperatures, power, and utilization levels. In response to the system data, this project explores the heat, temperature and power effects of adding insulation, varying water flow, CPU loading, and varying the cold plate-to-CPU clamping pressure. The idea is to provide an optimal and steady range of temperatures necessary for a chiller to operate. Results indicate an increasing relationship among CPU temperature, power and utilization. Since the dissipated heat can be captured and removed from the system for reuse elsewhere, the need for electricity-consuming computer fans is eliminated. Thermocouple readings of CPU temperatures as high as 93°C and a calculated CPU thermal energy up to 67Wth show a sufficiently high temperature and thermal energy to serve as the input temperature and heat medium input to an absorption chiller. This dissertation performs a detailed analysis of the exergy of a processor and determines the maximum amount of energy utilizable for work. Exergy as a source of realizable work is separated into its two contributing constituents: thermal exergy and informational exergy. The informational exergy is that usable form of work contained within the most fundamental unit of information output by a switching device within a CPU. Exergetic thermal, informational and efficiency values are calculated and plotted for our particular CPU, showing how the datasheet standards compare with experimental values. The dissertation concludes with a discussion of the work's significance.

Description
Energy consumption of the data centers worldwide is rapidly growing fueled by ever-increasing demand for Cloud computing applications ranging from social networking to e-commerce. Understandably, ensuring energy-efficiency and sustainability of Cloud data centers without compromising performance is important for both economic and environmental reasons. This dissertation develops a cyber-physical multi-tier server and workload management architecture which operates at the local and the global (geo-distributed) data center level. We devise optimization frameworks for each tier to optimize energy consumption, energy cost and carbon footprint of the data centers. The proposed solutions are aware of various energy management tradeoffs that manifest due to the cyber-physical interactions in data centers, while providing provable guarantee on the solutions' computation efficiency and energy/cost efficiency. The local data center level energy management takes into account the impact of server consolidation on the cooling energy, avoids cooling-computing power tradeoff, and optimizes the total energy (computing and cooling energy) considering the data centers' technology trends (servers' power proportionality and cooling system power efficiency). The global data center level cost management explores the diversity of the data centers to minimize the utility cost while satisfying the carbon cap requirement of the Cloud and while dealing with the adversity of the prediction error on the data center parameters. Finally, the synergy of the local and the global data center energy and cost optimization is shown to help towards achieving carbon neutrality (net-zero) in a cost efficient manner.

Description
Energy efficient design and management of data centers has seen considerable interest in the recent years owing to its potential to reduce the overall energy consumption and thereby the costs associated with it. Therefore, it is of utmost importance that new methods for improved physical design of data centers, resource management schemes for efficient workload distribution and sustainable operation for improving the energy efficiency, be developed and tested before implementation on an actual data center. The BlueTool project, provides such a state-of-the-art platform, both software and hardware, to design and analyze energy efficiency of data centers. The software platform, namely GDCSim uses cyber-physical approach to study the physical behavior of the data center in response to the management decisions by taking into account the heat recirculation patterns in the data center room. Such an approach yields best possible energy savings owing to the characterization of cyber-physical interactions and the ability of the resource management to take decisions based on physical behavior of data centers. The GDCSim mainly uses two Computational Fluid Dynamics (CFD) based cyber-physical models namely, Heat Recirculation Matrix (HRM) and Transient Heat Distribution Model (THDM) for thermal predictions based on different management schemes. They are generated using a model generator namely BlueSim. To ensure the accuracy of the thermal predictions using the GDCSim, the models, HRM and THDM and the model generator, BlueSim need to be validated experimentally. For this purpose, the hardware platform of the BlueTool project, namely the BlueCenter, a mini data center, can be used. As a part of this thesis, the HRM and THDM were generated using the BlueSim and experimentally validated using the BlueCenter. An average error of 4.08% was observed for BlueSim, 5.84% for HRM and 4.24% for THDM. Further, a high initial error was observed for transient thermal prediction, which is due to the inability of BlueSim to account for the heat retained by server components.

Description
This dissertation offers three essays that investigate consumers’ health-related food choices and behaviors from three different, yet complementary, angles. The first essay uses an eye-tracking experiment to examine consumers’ visual attention to the Nutrition Facts Panels for healthy and unhealthy products. In this essay, I focus on how involvement and familiarity affect consumers’ attention toward the Nutrition Facts panel and how these two psychological factors interact with new label format changes in attracting consumers’ attention. In the second essay, I demonstrate using individual-level scanner data that nutritional attributes interact with marketing mix elements to affect consumers’ nutrition intake profiles and their intra-category substitution patterns. My findings suggest that marketing-mix sensitivities are correlated with consumers’ preferences for nutrient attributes in ways that depend on the “healthiness” of the nutrient. For instance, featuring promotes is positively correlated with “healthy” nutritional characteristics such as high-protein, low-fat, or low-carbohydrates, whereas promotion and display are positively correlated with preferences for “unhealthy” characteristics such as high-fat, or high-carbohydrates. I use model simulations to show that some marketing-mix elements are able to induce consumers to purchase items with higher maximum-content levels than others. The fourth chapter shows that dieters are not all the same. I develop and validate a new scale that measures lay theories about abstinence vs. moderation. My findings from a series of experiments indicate that dieters’ recovery from recalled vs. actual indulgences depend on whether they favor abstinence or moderation. However, compensatory coping strategies provide paths for people with both lay theories to recover after an indulgence, in their own ways. The three essays provide insights into individual differences that determine approaches of purchase behaviors, and consumption patterns, and life style that people choose, and these insights have potential policy implications to aid in designing the food-related interventions and policies to improve the healthiness of consumers’ consumption profiles and more general food well-being.

Description
Most advanced economies have evolved into service economies with the majority of their activity and jobs being in the service sector. The manufacturing sector is also going through a similar shift towards services. Manufacturers are increasingly complementing their products with new services in order to satisfy a broader array of customer needs and increase the value of their offerings. This shift has offered significant opportunities to the sector and the success of major firms such as IBM, Caterpillar, and Rolls-Royce in competing through services has been remarkable.
Despite the increased importance of services in the manufacturing sector, the academic literature is yet to investigate the many questions that arise under this new manufacturing paradigm. Perhaps for the same reason study of servitization is listed as a research priority in recent publications both in the field of service operations management and in the field services marketing. This dissertation covers three essays aimed at disentangling multiple aspects of the role of services in the manufacturing sector. The literature on the drivers and implications of transition towards services in manufacturing firms is limited. The three studies in this dissertation aim at shedding light on this issue.
Specifically, the first essay looks at the innovation benefits of service transactions with customers. This paper demonstrate the value of services in getting manufacturers closer to customers and allowing them glean useful information from their service interactions. The second essay investigates the antecedents of service strategy adoption. We suggest that the extant diversification theory does not fully explain servitization and this phenomenon represents a unique type of diversification, which is likely driven by different factors. Through econometric analysis of financial data over a 27-year period, this study explores characteristics of product, firm resources, competition, and industry that encourage adoption of service strategies in manufacturing sector. Finally, the third essay takes a deeper dive and focuses on dealerships, as service centers, in the automobile industry. It investigates the role of dealerships in the success of automakers and explores dealership traits that are critical for market success of an automobile brand.

Description近20年,中国品牌零售业的快速发展使其成为全球第三大零售市场。消费者的需求量在大幅增长，对于本土企业来说，机遇与挑战并存。
对于连锁型品牌零售企业，员工是其产品和服务的载体。而如何做好不同层次的人员的激励体系，并得以踏实的落实和执行，是企业经营中非常关键的环节，也是品牌零售企业在竞争中获取优势的根本保证。另外，由于连锁零售企业基层员工流动性大、总体素质较低，如何对这部分员工实施有效的绩效考核,成为很多连锁零售企业管理人员面临的一个难题。
本文将长期和短期激励作为主要的研究内容。从整体国内企业来看，运转良好的绩效考评体系并不多，大部分企业的绩效考评体系只注重短期激励而忽视了长期激励的作用，绩效考评关注的是目标的实现，与员工的发展相脱节。因此，如何做好品牌企业的激励体系，如何在人才竞争中取得先机，并最大化企业利润，是本文研究的重心。
目前的研究空白在于对连锁型店铺的激励绩效。而考虑到品牌零售中的连锁经营往往涉及到成百上千家门店，涉及到的从业人数较多，因而对门店的激励绩效的成败是关系到企业整体激励绩效好坏的关键。
本文对激励绩效方案的相关理论进行回顾、分析与总结，从委托代理理论、激励理论、交易成本理论和产权理论入手，分析连锁型品牌零售企业的激励绩效特点。连锁型品牌零售企业合伙制本质上与特许经营精神及设计理念一致，而想要改进的正是特许经营中加盟店与总部的博弈与消耗，形成利益共同体，达到企业价值最大化的目标。
通过连锁型品牌零售企业绩效激励的真实案例（永辉超市合伙人制度、拉夏贝尔店铺合伙人制度、康奈零投入型与交股金型两种店铺合伙人制度）分析得出风险共担、超额利润分成的合伙人制度在连锁型品牌零售企业激励绩效方案设计中的可行性及意义，并从中发现了已有实践存在的问题，并提出建议。
店铺合伙人制度激励店长、提高单店销售业绩、减少交易成本、提高管理效率的正向作用毋庸置疑，建议在实践中积极推行与完善。
