A Novel Approach For Fabrication Of Single Silicon/Silicon Oxide Nanopillars At Precise Locations, Sravan Chowdary Talasila

Material Science and Engineering Theses - Archive

Nanopillars exhibit novel electrical and optical properties which could not be obtained from bulk materials. Many of their practical applications would require controlled placement of nanopillars at exact locations. However, precise placement and large scale fabrication of nanopillars have been challenging with conventional fabrication techniques. This thesis investigates a new approach to fabricate nanopillars at exact locations on a large scale. In this approach, fabrication of nanopillars is accomplished by first placing nanoparticles (NP) at exact locations and then performing anisotropic dry etching using these NPs as hard masks, resulting in formation of nanopillars on exact substrate positions. Precise placement …

Optimization Of Water And Energy Use In Indirect Evaporative Cooling System By Cfd, Mansi Vijay Prajapati

Mechanical and Aerospace Engineering Theses - Archive

Data center cooling is becoming important to maintain environmental condition for ITE- Information technology equipment. Conventional evaporative wet cooling media lowers the temperature of the dry bulb temperature of incoming air in which heat transfer to water film and sensibly cool the product air by increasing moisture into air. Wet cooling media technique requires large quantity of clean water, which is reducing area where water is very less. Therefore, indirect evaporative cooling is good alternative. Chiller plants/Indirect Evaporative cooling(IEC) are used as a cooling source for larger data centers as they are more efficient in heat transfer without adding moisture …

Finite Element Modeling And Stress Distribution Of Unidirectional Composite Materials Under Transversal Loading, Pavan Agarwal

Mechanical and Aerospace Engineering Theses - Archive

Micromechanics of Composites analyze stresses inside any heterogeneous material. These stresses can not only be used for calculation of effective stiffness or compliance, but also for predicting strength and failure modes for these materials. This thesis is devoted to the stress analysis of unidirectional composites by finite element method. The key distinction from other finite element method modeling of the unidirectional composite was that the load on the cell was not prescribed, but was to be calculated taking into account the influence of the closest neighbors of the cell. Transversal unidirectional tension/compression and transversally symmetrical biaxial tension/compression were analyzed. In …

Evaluation Of Water Consumption And Savings Achieved In Datacenters Through Air Side Economization, Ravi Mishra

Mechanical and Aerospace Engineering Theses - Archive

Recent researches and a few facility owners have focused on eliminating the chiller plant altogether by implementing ‘Evaporative Cooling’, as an alternative or augmentation to compressor-based air conditioning since the energy consumption is dominated by the compressor work (around 41%) in the chiller plant. Because evaporative cooling systems consume water, when evaluating the energy savings potential of these systems, it is imperative to consider not just their impacts on electricity use, but also their impacts on water consumption as well since Joe Kava, Google’s head of data center operations, was quoted as saying that water is the “big elephant in …

The symbiotic gut organisms of termites play an important role in lignocellulose digestion and other related metabolic processes. Previous studies on Diplosphaera colitermitum TAV2, a Verrucomicrobium isolated from the hindgut of Reticulitermes flavipes, revealed its microaerophilic nature and involvement in important ecophysiological processes in the termite gut. In the present study, a detailed account of genomic sequences of 3 additional strains is provided, and the genomes of all 5 TAV strains isolated so far are compared, to gain a comprehensive understanding of these organisms. Our comparative genomic study shows that these strains represent two distinct species, and despite significant number …

Navigating Women's Cultural Representation Through Video Games In The Obama Era, Mark Stephen Reeder

English Theses - Archive

While the representations of women in video games have remained disappointingly negative since the 1980s, America’s political shift from the presidencies of George W. Bush to Barack Obama in 2007 had important cultural implications, particularly impacting the representation of women in popular culture. This thesis will examine the cultural depictions of women from 2002-2011, providing a particular focus on the unique cultural factors prevalent during this time period—including the expansion of pornography, a conservative cultural backlash to Obama, and the rapid deterioration of ‘political correctness’—that impacted how images of women in video games were received. Analyzing the cultural atmosphere of …

The World In The Screen: How The Mobile Device Symbolizes Technogenesis, Joel Mathew Morrow

English Theses - Archive

The smart phone, or mobile device, holds a preeminent role in a technologically advanced society. These devices allow for connection, productivity, and distraction, and in doing so create new anxieties and underscore old ones. By tracing the provenance of this artifact, we see how our relationship with mobile devices amplifies our relationship with technology as a whole. This thesis examines the development of the mobile device from the viewpoints of social constructivism and technogenesis to illustrate how our increasing intimacy with these devices is part of a long-standing pattern of co-evolution between humans and the technologies they create.

A Self-Regulated Learning Inventory Based On A Six-Dimensional Model Of Srl, Christopher Nuttall

Theses and Dissertations

This report discusses a study undertaken to develop, pilot, and tentatively validate a self- regulated learning (SRL) inventory for L2 contexts. This inventory was specifically designed to measure learners' ability to self-regulate their learning. Although there have been a few SRL inventories developed to measure this ability, they do not conform to the six-dimensional SRL model proposed by educational psychologists and backed by extensive research. This warranted the development of a new SRL inventory. The primary focus of this study was that of taking initial steps to develop such an inventory. These steps involved writing and refining items conforming to …

Learning To Mock - Challenging The Teaching Establishment, N Gabriel

Plymouth Institute of Education

There have been very few studies that apply the work of Mikhail Bakhtin and Norbert Elias to understand the underlying learning processes of young children. This article will explore the methodological similarities between Bakhtin’s ideas about the carnivalesque and Norbert Elias’s theory of established-outsider relations to explain how young children can undermine the authoritative discourses of teachers in preschool classrooms. It will focus on the playful mockery that young children display within their peer-groups to challenge teaching authority. I will argue that many of the humorous events produced by young children should be viewed as an attempt to violate their …

From Global To Local: Reshoring For Sustainability, Al Ashby

Plymouth Business School

The UK clothing industry has seen the extensive offshoring of manufacturing, which has created fragmented global supply chains; these present a range of supply issues and challenges, including many related to sustainability. Reshoring is a reversion of a previous offshoring decision, thereby ‘bringing manufacturing back home’ (Gray et al. J Supply Chain Management 49(2):27–33, 2013), and can be motivated by increased costs and supply management problems. While not a new phenomenon, the reshoring of activities is growing in practice and there is an imperative for academic research (Fratocchi et al. J Purch Supply Manag 20:54–59, 2014). Through an in-depth longitudinal …

The purpose of this study was to investigate the effects that simulations using social media have on learning of crisis communication among college students. To explore the effects, a real-time crisis simulation activity using social media are created for 132 undergraduate students enrolled at a business school. Both quantitative and qualitative data collected from pre- and post-simulation surveys are used to investigate the benefits of simulations on learning and identify the challenges the participants experienced.

Mythbusting Park Chung Hee: A Reexamination Of Park And His Coup, Justin Malzac

Electronic Theses & Dissertations

Park Chung-Hee is a divisive figure. For some he is a saint that rescued his country from the brink of collapse and helped it rise into modernity. For others he is a devil, an iron-fisted dictator who cared more about his own power than his people. Both of these are politically slanted myths promoted as part of a corresponding political agenda. But even politically neutral writings on Park unwittingly conduct a mythmaking of their own. This paper is an attempt to show that Park Chung-Hee has become a mythological figure in Korean history because the scope of his power, agency …

Like A Duck On Water: Chinese Academic Migrants In The U.S. And Their Suburban Weekend Chinese School, Jianping Xu

Dissertations - ALL

Current literature is scarce on the diverse experiences of hundreds of thousands of mainland Chinese who, since 1979, have come to the U.S. primarily for graduate study and mostly settled here afterwards in dispersed university or corporate jobs and suburban residences. After the Immigration Act of 1990, many of them have become visible experts in science and engineering. Yet their struggles as Chinese academic migrants simultaneously privileged by their educational backgrounds and disadvantaged by their outsider status in the U.S. often remain invisible. Possibly due to the myth of “model minority,” mainstream America has seen them as doing-well and well-behaving, …
