Emission Reduction In Small Displacement Diesel Engines Using Cooled Exhaust Gas Recirculation, Chris Simoson

All Theses

A reduced-order dynamic model is presented and experimentally validated to demonstrate the use of cooled exhaust gas recirculation to alleviate the tradeoff between nitric oxide reduction and performance preservation in a small displacement diesel engine. Exhaust gas recirculation (EGR) is an effective method for internal combustion engine oxides of nitrogen (NOx) reduction, but its thermal throttling diminishes power efficiency. The capacity to cool exhaust gases prior to merging with intake air may achieve the desired pollutant effect while minimizing engine performance losses.
Simulation and experimental results revealed significant NOx reductions throughout all testing scenarios using EGR, but also experienced a …

Influence Of Temperature And Polymer/ Mold Surface Interactions On Micro-Feature Replication At Ambient Pressure In Micro Injection Molding, Varun Thakur

All Theses

This study assesses micro-feature replication at elevated mold temperature and ambient pressure using a variety of polymers. Moldings were made on the surface of stainless steel and silicon wafers containing features as small as 130 nm under isothermal conditions in a heated chamber by allowing polymer to spread over the features at ambient pressure. Feature replication was analyzed via AFM and SEM. Polymer behavior was characterized via melt contact angle and melt viscosity. While feature detail was well replicated, the moldings exhibited poor dimensional accuracy due to shrinkage. In general, polymers with low viscosity and surface tension comparable to the …

Discrete Asymptotic Abstractions Of Hybrid Systems, Chaouki T. Abdallah, Jorge L. Piovesan, Herbert G. Tanner

Electrical & Computer Engineering Faculty Publications

In this paper we introduce the notion of finite time mode abstraction to relate a hybrid automaton to a timed automaton that preserves the stability and reachability properties of the former. The abstraction procedure discards the continuous dynamics of each mode in the hybrid automaton completely, keeping only the information about the maximum time in which the continuous state makes a discrete jump. This information is used to construct a timed automaton, based on the original hybrid automaton, and to prove that the stability and reachability properties of the original system are retained in the abstract timed automaton. In the …

Psychogenic Stuttering Following A Gastric Bypass Operation: Case Report, Deborah B. Raphael M.D. (Pgy2), Frank B. Schoenfeld M.D.

Jefferson Journal of Psychiatry

We evaluated a 44-year-old female with bipolar affective disorder who presented with a 4-month history of severe stuttering and vague neurologic complaints. She had lost 200 pounds after gastric bypass surgery two years before. A childhood sexual-abuse victim, she admits that she "hid" in her weight for most of her life. Neurological evaluation of this patient was negative, and speech-pathology evaluation revealed highly atypical stuttering. Gastric bypass patients with a history of psychiatric disorders and childhood sexual abuse may be particularly vulnerable to somatoform disorders.

Translated Opinions

Facts: The respondents introduced a compulsory retirement age of 55 for all of their employees. The petitioners challenged this policy on the grounds that it discriminated between them and civil servants in other parts of the civil service, where the customary retirement age was 65.

Held: Although the law gave the respondents the possibility of retiring its employees at the age of 55, the introduction of a compulsory retirement policy at the lowest age allowed by the law resulted in discrimination in relation to the other parts of the civil service. This consideration had not been taken into account by …

Investigation Of Flow And Microstructure In Rheometric And Processing Flow Conditions For Liquid Crystalline Pitch, Santanu Kundu

All Dissertations

A fundamental understanding of flow and its influence on the microstructure is required to obtain carbon materials with desired properties. The objective of this research was to investigate the flow and microstructural behavior of a synthetic mesophase pitch (AR-HP) in rheometric and processing flow conditions. In addition, simulation studies were performed to establish a frame work for modeling the flow behavior of this complex material in different flow situations.
The steady-shear viscosities obtained from a cone-plate rheometer during increasing rate-sweep experiments exhibited a shear-thinning region (Region I) with a slope of about -0.2 and a plateau (Region II) region. The …

Use Of Personas For User Interface Design: Results Of Field And Experimental Studies , Pallavi Dharwada

All Dissertations

Persona is a fictitious user serving as a role model for designers, helping them make difficult decisions from the users' perspective during the interface design process. This concept, which was introduced by Alan Cooper in 1999, has been found to be a powerful tool for engaging the designers with the users. Although personas do not replace the rich data acquired through user testing, they enhance the interface development process by focusing the designers' attention on the target user until the interface qualifies for testing. Recognizing the benefits of persona, many companies, including the Fortune 500 have embraced this concept as …

As a means of thermal management, uses of heat pipe technology not only include thermal control of satellites and spacecrafts in aerospace applications, but also the cooling of electronic components for ground applications. Recently, there has been a flourishing interest in exploring the use of heat pipe technology in the automotive field. However, in many thermal control applications, heat pipes using room-temperature working fluids, such as water or ammonia, with operating temperatures between 200 K (-73ºC) and 550 …

Development Of A Cellular Fiber Spinning Technology For Regenerative Medicine, Willie Jones

All Theses

In order to prove that our textile hollow fiber spinning apparatus was adequate for cellular encapsulation, we confirmed the viability and metabolic activity of green fluorescent protein (GFP) labeled bovine mammary epithelial cells (MAC-Ts) that were encapsulated in either the wall or lumen of alginate fibers. After a 21 day in vitro macroscopic evaluation, no decrease in fluorescence was observed; and it was determined that MAC-Ts encapsulated under both methods produced lactic acid and consumed glucose. Histomorphological analyses revealed that the diameter of the MAC-Ts increased under both encapsulation scenarios, with little to no evidence of cell cluster propagation. Based …

Sorting Through Distortion, Kathryn Hutter

All Theses

The relationship of the recurrent visual signals in contemporary culture and the physical routine of living in the culture begin to build as layers in the fabric or patterns of everyday. My use of pattern (both mass produced fabric, and painted surface) imitates the repetitious nature of visual stimuli in American culture as well as the viewer's familiarity with object and image recognition. I investigate the language of signals and human thinking relying heavily on the viewer's link to familiarity and how that may provoke them to read the paintings. To do this, I draw directly from the use of …

Dielectric Properties And Method Of Characterizing Ceramic Powders And Multiphase Composites, Ravi Kiran Kota

All Theses

Barium Titanate was the first developed ferroelectric ceramic material and even today it is widely used. It is also a well-known material used for capacitors. The only reason behind a wide range of applications is that barium titanate boasts of high dielectric properties. A phase transition from cubic to tetragonal at normal working temperatures provides enhanced dielectric properties in this electronic material. For any application and design, the most inquired property is the dielectric constant. Predicting the dielectric constant is very much required as it is the pre-requisite. This is the major objective of the present work. To estimate the …

European Private Law: A Plea For A Spontaneous Legal Order, Jan M. Smits

ExpressO

This contribution focuses on European integration through private law. After a sketch of the existing European acquis in the field of the law of contract, tort and property, the question is discussed whether there is a need for harmonisation in view of the goals the European Union set itself. Subsequently, the question of how to design a future European private law is answered. In the field of contract law, the European Commission now follows a two-track policy: it intends to draft a ‘Common Frame of Reference’ (‘CFR’) as well as furthering the debate on the possibility of an optional code. …
