Rheology Of Polyaniline Dispersions In Acrylic Resin, Nicoleta Plesu, Smaranda Iliescu, Gheorghe Ilia, Adriana Popa, Cornelia Muntean

Turkish Journal of Chemistry

Acrylic dispersions based on polyaniline were obtained and characterised. The polyaniline was obtained by chemical polymerisation of aniline in different organic acid containing phosphorous, in the presence of ammonium-peroxidisulphate as oxidant agent. The blends were obtained by mechanical dispersion of polyaniline in commercially available acrylic resin. The flow behaviour of these dispersions at different shear rates was studied. Furthermore, the resulting acrylic dispersions were analysed by IR spectroscopy, and were characterised in terms of their electrical resistance and rheological behaviour

Streaming Video Performance And Enhancements In Resource-Constrained Wireless Networks, Justin James Madigan

Theses

Streaming video is an increasingly popular application in wireless networks. The concept of a live streaming video yields several enticing possibilities: real-time video conferencing, television broadcasting, pay-per-view movie streaming, and more. These ideas have already been explored via the internet and have met with mixed success, largely due to the shortcomings of the underlying network. Taking streaming video to wireless networks, then, poses several significant challenges. Wireless networks are inherently more susceptible to failures and data corruption due to their unstable communications medium. This volatility suggests serious drawbacks for any implementation of streaming video. Video frame errors, jitter, and even …

Design Of Partial Enclosures For Acoustical Applications, Amy Elizabeth Carter

University of Kentucky Master's Theses

Enclosures are a very common way to reduce noise emissions from machinery. However, enclosures display complex acoustic behavior that is difficult to predict. The research presented in this thesis uses the boundary element method in order to better understand the acoustic behavior of a partial enclosure. Insertion loss was used as the performance measure and the effect of several design factors on the overall insertion loss was documented. Results indicate that the most important factors affecting enclosure performance are the opening size, amount of absorption, and the source-to-opening distance.

Characterization And Measurement Of Tension-Induced Longitudinal Wrinkles In Gossamer Membranes Using Photogrammetry, Sreeram Mangalampalli

University of Kentucky Master's Theses

Gossamer membranes are large, ultra light weight, highly flexible thin films. They have been proposed for use as elements in systems such as solar sails and optical apertures, whose large areas require a low-mass material that can be launched in a compact package and then deployed to operational configuration upon reaching orbit. Many of the proposed applications require that the film possess a flat, wrinkle-free surface. Surface wrinkle configuration is determined, in part, by the method used to support the film. One configuration that has not been studied in detail involves the formation of vertical wrinkles oriented along the direction …

Experimental Study Of Flow Boiling Heat Transfer And Critical Heat Flux In Microchannels, Wai Keat Kuan

Theses

Advancements in microprocessors and other high power electronics have resulted in increased heat dissipation from those devices. In addition, to reduce cost, the functionality of microprocessor per unit area has been increasing. The increase in functionality accompanied by reduction in chip size has caused its thermal management to be challenging. In order to dissipate the increase in heat generation, the size of conventional fin-type heat sinks has to be increased. As a result, the performance of these high heat flux generating electronics is often limited by the available cooling technology and space to accommodate the larger conventional air-cooled heat sinks. …

Horn Formula Minimization, Tom Chang

Theses

Horn formulas make up an important subclass of Boolean formulas that exhibits interesting and useful computational properties. They have been widely studied due to the fact that the satisfiability problem for Horn formulas is solvable in linear time. Also resulting from this, Horn formulas play an important role in the field of artificial intelligence. The minimization problem of Horn formulas is to reduce the size of a given Horn formula to find a shortest equivalent representation. Many knowledge bases in propositional expert systems are represented as Horn formulas. Therefore the minimization of Horn formulas can be used to reduce the …

Jacil: A Cli To Jvm Compiler, Almann Goo

Theses

Both the .NET Framework via the Common Language Infrastructure (CLI) and the Java Virtual Machine (JVM) provide a managed, virtual execution environment for running high-level virtual machine code. As these two platforms become ubiquitous, it is of pragmatic and academic interest to have the capability of running CLI code on the JVM and vice versa. This project developed JaCIL (pronounced "jackal"), a CLI assembly to JVM class file bytecode compiler framework. JaCIL also provides a user program for running CLI-to-JVM translations and a runtime library to support the translated code.

Landscapes Of Imagination: A Critical Analysis Of Art Textbooks, Lynda C. Kerr

College of Graduate Studies: Theses & Dissertations

Author's abstract: This qualitative study examined imagination in secondary art textbooks, both historically and in the current educational climate. An arts-based inquiry, as described by Barone & Eisner (Jaeger, 1988), investigated how imagination is manifested in some art books, how the standards movement has tended to limit imagination in art textbooks, and how art textbooks could expand students' imaginations. Using a framework based on the theories of Dewey (1934/1980), Greene (2001), and Eisner (2002), four art textbooks were analyzed for their qualities which expand students' imaginations. The study described a design for an imaginative art textbook. Analysis focused on the …

A Code Of Conduct For Indonesia: Problems And Perspectives, Riccardo Pelizzo, Bernice Ang

Research Collection School of Social Sciences

The purpose of the present paper is fairly straightforward. We want to show that institutional reforms, such as the adoption of a conduct code, represent a necessary albeit insufficient condition to curb corruption and promote good governance. As several scholars have pointed out the success of institutional reform in general and the success of codes of conduct in particular depends, among other things, on ideational conditions. With regard to codes of conduct, parliamentary ethics experts believe in fact that the success of a code of conduct depends on whether the individuals who are supposed to be regulated by the disposition …

Labeling Genetically Modified Food: Comparative Law Studies From Consumer's Perspective, Christopher C. H. Chen

Research Collection Yong Pung How School Of Law

This article focus on the genetically modified food and labelling requirement. The relatively new technology raises some concerns over the safety of food containing genetically modified substance. The "substantial equivalent" doctrine, adopted by the U.S., and the "precautionary" doctrine, taken by the EU, represent two contradictory approaches to reconcile new biotechnology and consumer protection, a difference influenced by politics or food industry rather than by consumer attitudes. In this article, we argue that consumers cannot make their own choices and exercise market power without a certain degree of disclosure of information. However, even though food labelling is an effective way …

Superabsorbency, Ph-Sensitivity And Swelling Kinetics Of Partially Hydrolyzed Chitosan-G-Poly(Acrylamide) Hydrogels, Ali Pourjavadi, Gholam Reza Mahdavinia

Turkish Journal of Chemistry

Acrylamide (AAm) monomer was directly grafted onto chitosan using ammonium persulfate (APS) as an initiator and methylenebisacrylamide (MBA) as a crosslinking agent under an inert atmosphere. Two factors affecting the swelling capacity of the obtained hydrogel, AAm and MBA concentrations, were studied. The polymer structures were characterized by FTIR spectroscopy. Water absorbencies of the hydrogels were compared between before and after the alkaline hydrolysis treatment. Saponification of chitosan-g-poly(acrylamide) (chitosan-g-PAAm) with a hot sodium hydroxide solution gave rise to a high water absorbency. Swelling of the hydrogel samples in saline solution (0.15 mol/L NaCl, CaCl_2 and AlCl_3) was examined. Swelling capacity …
