Consumers And Sustainability At Walmart: A Student's Perspective, Kealy Carter, Satish Jayachandran

Wal-Mart Sustainability Case Project

To further encourage students to analyze initial goals in comparison with outcomes over time, we have developed a consumer-oriented case—“Consumers and Sustainability at Walmart: A Student’s Perspective”—that moves beyond the perspective of internal Walmart participants to explores issues of sustainability from the point of view of a typical Walmart shopper. In this case, we examine the experience of a fictional student shopper who goes to Walmart and wants to buy sustainable products, which helps raise questions for students about what Walmart’s actions mean to them as consumers, citizens as well as business professionals. The case also asks students to evaluate …

Increased Normal Incidence Photocurrent In Quantum Dot Infrared Photodetectors, Jiayi Shao, Thomas E. Vandervelde, Ajit Barve, Andreas Stintz, Sanjay Krishna

Birck and NCN Publications

We have increased the ratio of s-polarization (normal incidence) to p-polarization photocurrent to 50% in a quantum dot-in-a-well based infrared photodetector form the typical s-p polarization ratio about 20%. This improvement was achieved by engineering the dot geometry and the quantum confinement via post growth capping materials of the Stranski Krastanov growth mode quantum dots (QDs). The TEM images show that the height to base ratio of shape engineered QDs was increased to 8 nm/12 nm from the control sample's ratio 4 nm/17 nm. The dot geometry correlates with the polarized photocurrent measurements of the detector. (C) 2012 American Institute …

Cloud Computing For Environment-Friendly Data Centers, Michael Pawlish, Aparna Varde, Stefan Robila

Department of Computer Science Faculty Scholarship and Creative Works

The purpose of this paper is to analyze the carbon footprint and utilization rates in a data center. The long-term goal of this work is to give data center administrators an enhanced perspective of data center operations to allow for more energy efficient operation, to lower the carbon footprint, and to promote green data centers. Previous literature shows that low utilization rates in data centers are due to the forecasting of demand to meet spikes in data center use. This management policy has led to many servers running idle the majority of the time which is a waste of resources. …

Thin Films Of Carbon Nanotubes And Nanotube/Polymer Composites, Anthony D. Willey

Theses and Dissertations

A method is described for ultrasonically spraying thin films of carbon nanotubes that have been suspended in organic solvents. Nanotubes were sonicated in N-Methyl-2-pyrrolidone or N-Cyclohexyl-2-pyrrolidone and then sprayed onto a heated substrate using an ultrasonic spray nozzle. The solvent quickly evaporated, leaving a thin film of randomly oriented nanotubes. Film thickness was controlled by the spray time and ranged between 200-500 nm, with RMS roughness of about 40 nm. Also described is a method for creating thin (300 nm) conductive freestanding nanotube/polymer composite films by infiltrating sprayed nanotube films with polyimide.

The Far Field Transformation Using The Iterative Srm Based On The Phaseless Data, Ping Li, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Conventional equivalent source reconstruction methods (SRM) require both phase and amplitude information of the field data. However, there are situations where the phase information is not easy to obtain. Hence, developing novel SRM based on phaseless data is necessary. In this paper, a novel iterative SRM based on two sets of measured phaseless data is presented. It can reproduce the 3D radiation pattern with very good accuracy. Integral equation (IE) is employed to build reconstruct equivalent source. Combined field IE (CFIE) is also employed to obtain more physical current distribution. © 2012 IEEE.

A Single-Layer Compact Hf-Uhf Dual-Band Rfid Tag Antenna, Zi Long Ma, Li (Lijun) Jun Jiang, Jingtian Xi, Terry Tao Ye

Electrical and Computer Engineering Faculty Research & Creative Works

This letter presents a novel dual-band (HF and UHF) radio frequency identification (RFID) tag antenna. Two key challenges are faced: the compact dimension and the impaired bandwidth due to the couplings between two band structures. To enable the implementation of whole design on a credit-card-size single-layer support, a spiral coil along the edges of the card is designed to handle the HF (13.56 MHz) near-field coupling, and the UHF antenna is placed inside the coil instead of outside. Meanwhile, a diagonal symmetric design consisting of two meander lines inside the spiral coil is adopted for UHF band. This structure supports …

Integral Equation Method For Analyzing Purcell Effect In Plasmonic System, Yongpin P. Chen, Weng Cho Chew, Wei E.I. Sha, W. C.H. Choy, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Integral equation method is applied to analyze the Purcell effect in plasmonic system in this paper. By applying the Fermi's golden rule, the Purcell effect of a quantum emitter can be calculated from the local density of states (LDOS), which can be further expressed by the imaginary part of the Green's function of the whole system. To obtain this Green's function numerically, the layered medium Green's function is utilized to simplify the modeling of planarly layered substrate, where the surface plasmon polaritons (SPPs) can be sustained. The metallic nano scatterers are introduced to excite the localized surface plasmons (LSP), and …

Reliability Evaluation Of Distribution Systems Containing Renewable Distributed Generations, Abdulaziz A. Alkuhayli, Srinath Raghavan, Badrul H. Chowdhury

Electrical and Computer Engineering Faculty Research & Creative Works

Reliability evaluation of distribution networks under grid-tied and islanded microgrid modes is presented. the Monte Carlo simulation (MCS) algorithm is applied to a modified RBTS Bus 2 distribution network. the network includes three types of distributed energy resources, namely, solar photovoltaic (PV), wind turbine (WT), and diesel turbine generator (DTG). These distributed generators contribute to supply part of the load during grid-connected mode but supply 100% of the load in the islanded microgrid mode. This study shows that the implementation of distributed generations can improve the reliability indices of the distribution network. © 2012 IEEE.

College Departure: Exploring Student Aid Effects On Multiple Mobility Patterns From Four-Year Institutions, Dongbin Kim, Argun Saatcioglu, Amy Neufeld

Journal of Student Financial Aid

College departure involves multiple mobility patterns that include lateral transfer (from a four-year to another four-year institution), reverse transfer (from a four-year to a two-year institution), and stop out (taking time out of higher education altogether). This study addresses how financial aid influences the likelihood of such mobility patterns for minority and low-income students. Utilizing data from the Education Longitudinal Survey of 2002, this study found that the effects of financial aid on multiple mobility patterns are similar across students of different income groups. By contrast, non-white students benefit significantly from financial aid, particularly from low-burden aid options (e.g., tuition …

The Effects Of Freestream Turbulence On Serpentine Diffuser Distortion Patterns, Jesse Scott Johnson

Theses and Dissertations

Serpentine diffusers have become a common feature in modern aircraft as they allow for certain benefits that are impossible with a traditional linear configuration. With the benefits, however, come certain disadvantages, namely flow distortions that reduce engine efficiency and decrease engine surge stability margins. These distortions are now being researched comprehensively to determine solutions for mitigating the adverse effects associated with them. This study investigates how varying the freestream turbulence intensity of the flow entering a serpentine diffuser affects the distortion patterns that are produced by the diffuser. Experiments were performed with a model serpentine diffuser on the Annular Cascade …

Predicting Stock Market Using Online Communities Raw Web Traffic Streams, Pierpaolo Dondio

Articles

This paper investigates the predictive power of online communities traffic in regard to stock prices. Using the largest dataset to date, spanning 8 years and almost the complete set of SP500 stocks, we analyze the predictive power of raw unstructured traffic by filtering stock daily returns with traffic features. Our results partially challenge the assumption that raw traffic simply trails stock prices, as expected from a noisy signal without the sentiment direction. Raw traffic is shown to predict prices with statistical significance but with small economic impact. Anyway, this impact rises to moderate under the following conditions: 3 to 7 …
