The Electrocatalystic Investigation Of 3,4-Dihydroxybenzoic Acid On The Modified Multiply Wall Carbon Nanotubes, Ming-Qi Li, Duo-Chang Cai, Xiao-Ying He

Journal of Electrochemistry

The electrochemical behavior of 3,4-Dihydroxybenzoic acid(DHBA) on modified multiply wall carbon nanotubes electrode was investigated by cyclic voltammetry(CV) and square wave voltammetry(SWV). Results show that in 0.1 mol/L HCl solutions the modified carbon nanotube electrode has an obvious electrocatalytic effect on the oxidation and deoxidization of DHBA. The oxidation current of DHBA is linear to it's concentration in the range of 4.0×10-6～1.0×10-4 mol/L and 2.0×10-4～8.0×10-4 1mol/L with correlation coefficient of 0.9995 and 0.9992. The detection limit is 1.0×10-6 mol/L.

A Gasless Method Of Spraying Thermoplastic Resin, Dan T. Rogers Nov 2005

A Gasless Method Of Spraying Thermoplastic Resin, Dan T. Rogers

Theses and Dissertations

This spraying method for thermoplastic resins is a new manufacturing process for applying thermoplastics to a mold or surface in an efficient way that has the potential of reducing cycle time. Spraying thermoplastic resins is similar to spraying other polymers, such as paint, with the differences being higher pressure and temperature. This method uses an injection molding machine with a modified nozzle to spray the plastic material. In this study, temperature, pressure, and nozzle size were factors that influenced the success of this spraying method. The method of spraying in this study proved spraying without a gas is possible, a …

Inclusive jet cross sections in photoproduction for events containing a D* meson have been measured with the ZEUS detector at HERA using an integrated luminosity of 78.6 pb-1. The events were required to have a virtuality of the incoming photon, Q2, of less than 1 GeV2, and a photon-proton centre-of-mass energy in the range 130 < Wγp < 280 GeV. The measurements are compared with next-to-leading-order (NLO) QCD calculations. Good agreement is found with the NLO calculations over most of the measured kinematic region. Requiring a second jet in the event allowed a more detailed comparison with QCD calculations. The measured dijet cross sections are also compared to Monte Carlo (MC) models which incorporate leading-order matrix elements followed by parton showers and hadronisation. The NLO QCD predictions are in general agreement with the data although differences have been isolated to regions where contributions from higher orders are expected to be significant. The MC models give a better description than the NLO predictions of the shape of the measured cross sections. © 2005 Elsevier B.V. All rights reserved.

An Investigation On Poly(Vinyl Chloride-Co-Isobutyl Vinyl Ether) Coatings Modified By Rutile Nano-Tio2 Pastes, Xiang Bin, Sheng-Tao Zhang, Yan Li, Bao-Rong Hou

Journal of Electrochemistry

The anti-corrosion coating of Poly(Vinyl Chloride-Co-Isobutyl Vinyl Ether) (PVCCIVE) was modified by rutile nano-TiO2. The influence of nano-TiO2 pastes on the coating's corrosion resistance was investigated through electrochemistry impedance spectroscopy (EIS). The results show that the addition of nano-TiO2 pastes does not have obvious effect on the coating's performance of adhesion, flexility, impact resistance, but improves the coating's UV resistance and the gloss.Meanwhile,with the proper addition of rutile nano-TiO2 pastes, the anti-corrosion behavior of the coating was advanced.

A Study Of Overcharge Characteristic Of Lithium-Ion Cells, Jing Pang, Shi-Gang Lu, Sha Liu Nov 2005

A Study Of Overcharge Characteristic Of Lithium-Ion Cells, Jing Pang, Shi-Gang Lu, Sha Liu

Journal of Electrochemistry

The overcharge characteristics and effect factors of lithium-ion cells containing LiMn2O4 cathodes were studied in detail. Overcharge testing of Lithium-ion cells with a systematic variation in the cell balance demonstrated that the overcharge characteristics of Lithium-ion cells was affected by the amount of cathode in the cells, which is independent of the amount of anode material. The rate of charge was found to be an important parameter, as electrolyte complete decomposition at low charge rates caused the end of overcharge testing, while high charge rates accelerated the rate of heat generation in the cells and the cell …

Electrochemical Oxidation Of Organic Additives In Tin Plating Electrolytes, Yin-Mei Cheng, Lan-Kun Cai, Qiang Song Nov 2005

Electrochemical Oxidation Of Organic Additives In Tin Plating Electrolytes, Yin-Mei Cheng, Lan-Kun Cai, Qiang Song

Journal of Electrochemistry

Cyclic voltammetry(CV) was used to characterize the voltammetric behaviours of organic additives, e.g. PSA(phenolsulfonic acid) EN(ethoxylatedα-naphthol) and ENSA(ethoxylatedα-naphthol sulfonic acid), on the anode surface. In PSA solutions, an anodic peak was obtained and the peak potential was about 1.2V. In EN and ENSA solutions, two anodic peaks were obtained and the peak potentials were about(0.95V) and 1.3V. The products of galvanostatic electrolysis were separated by HPLC(high performance liquid chromatography) and analyzed by EI/MS(electron ionizing mass spectrometry). The mechnism of the electrochemical oxidation was also disussed.

A Brain-Computer Interface To Control A Prosthetic Hand / Yong Xin Yi, Xin Yi Yong Nov 2005

A Brain-Computer Interface To Control A Prosthetic Hand / Yong Xin Yi, Xin Yi Yong

Student Works (2000-2009)

A Brain-Computer Interface (BCI) system was developed to operate a prosthetic hand and other devices. The Electroencephalogram (EEG) signals were recorded over the sensorimotor cortex area during foot, left or right hand motor imagery. Only two mental tasks and one or two EEG bipolar channels were identified and used in the online experiments. Autoregressive (AR) modeling was used to extract the features from the spontaneous EEG signals and Linear Discriminant Analysis (LDA) was used as the classifier. Six subjects participated in the online study. However, only three subjects had sufficient control to proceed to the final application phase. The online …

Ontoqa: Metric-Based Ontology Quality Analysis, Samir Tartir, I. Budak Arpinar, Michael Moore, Amit P. Sheth, Boanerges Aleman-Meza

Kno.e.sis Publications

As the Semantic Web gains importance for sharing knowledge on the Internet this has lead to the development and publishing of many ontologies in different domains. When trying to reuse existing ontologies into their applications, users are faced with the problem of determining if an ontology is suitable for their needs. In this paper, we introduce OntoQA, an approach that analyzes ontology schemas and their populations (i.e. knowledgebases) and describes them through a well defined set of metrics. These metrics can highlight key characteristics of an ontology schema as well as its population and enable users to make an informed …

The Perils Of Higher Skill Shortages For Pakistan’S Economy, Ishrat Husain Dr. Nov 2005

The Perils Of Higher Skill Shortages For Pakistan’S Economy, Ishrat Husain Dr.

Faculty Research - Talks, Speeches, & Discourse

It is highly paradoxical that in a developing country such as Pakistan, we are experiencing serious skill shortages and, at the same time, high rates of open and under employment. A lot has already been said about the causes of the mismatch between the skills required by the economy and the skills generated by the educational institutions. In this paper, I am also not going to focus on technical and vocational skills such as carpenters, masons, electricians, plumbers, automobile, air conditioning, refrigeration mechanics, medical technicians, nurses, foremen, etc. but mostly on higher skills such as needed by the I.T. and …

The Laser Interferometer Gravitational-Wave Observatory has performed a third science run with much improved sensitivities of all three interferometers. We present an analysis of approximately 200 hours of data acquired during this run, used to search for a stochastic background of gravitational radiation. We place upper bounds on the energy density stored as gravitational radiation for three different spectral power laws. For the flat spectrum, our limit of 0 < 8.4 × 10 -4 in the 69-156 Hz band is ∼10 5 times lower than the previous result in this frequency range. © 2005 The American Physical Society.

Boilerplate And Economic Power In Auto Manufacturing Contracts, Omri Ben-Shahar, James J. White Nov 2005

Boilerplate And Economic Power In Auto Manufacturing Contracts, Omri Ben-Shahar, James J. White

Law & Economics Working Papers Archive: 2003-2009

This article studies the standard form contracts used by automobile manufacturers to purchase auto parts. It explores how the contracts reflect divisions of bargaining power, asymmetric information, problems of hold-up and renegotiation, and market competition. Based on interviews with representatives of buyers and suppliers, the article also describes the process of drafting the forms, the negotiation over price and other terms in the shadow of these forms, and the opportunities for non-drafters to extract improved terms. Some of the main lessons are: (i) The terms of the contracts and the bidding process prevent ex-post hold-up by suppliers (in contrast to …

Composable Models For Timing And Liveness Analysis In Distributed Real-Time Embedded Systems Middleware, Venika Subramonian, Christopher Gill, Cesar Sanchez, Henry B. Sipma Nov 2005

Composable Models For Timing And Liveness Analysis In Distributed Real-Time Embedded Systems Middleware, Venika Subramonian, Christopher Gill, Cesar Sanchez, Henry B. Sipma

All Computer Science and Engineering Research

Middleware for distributed real-time embedded (DRE) systems has grown increasingly complex, to address functional and temporal requirements of diverse applications. While current approaches to modeling middleware have eased the task of assembling, deploying and configuring middleware and the applications that use it, a lower-level set of formal models is needed to uncover subtle timing and liveness hazards introduced by interference between and within distributed computations, particularly in the face of alternative middleware concurrency strategies. In this paper, we propose timed automata as a formal model of low-level middleware building blocks from which a variety different middleware configurations can be constructed. …

Roadmap Query For Sensor Network Assisted Navigation In Dynamic Environments, Sangeeta Bhattacharya, Nuzhet Atay, Gazihan Alankus, Chenyang Lu, O. Burchan Bayazit, Gruia-Catalin Roman

All Computer Science and Engineering Research

Autonomous mobile entity navigation through dynamic and unknown environments is an essential part of many mission critical applications like search and rescue and fire fighting. The dynamism of the environment necessitates the mobile entity to constantly maintain a high degree of awareness of the changing environment. This criteria makes it difficult to achieve good navigation performance by using just on-board sensors and existing navigation methods and motivates the use of wireless sensor networks (WSNs) to aid navigation. In this paper, we present a novel approach that integrates a roadmap based navigation algorithm with a novel network query protocol called Roadmap …

Object Oriented Cae Software For The Exploration And Design Of Microstructures, Stephen D. Sintay Nov 2005

Object Oriented Cae Software For The Exploration And Design Of Microstructures, Stephen D. Sintay

Theses and Dissertations

Through the use of generalized spherical harmonic basis functions a spectral representation is used to model the microstructure of cubic materials. This model is then used to predict the macroscopic elastic and plastic properties of materials with cubic crystal symmetry and various sample symmetry including triclinic and axial—symmetric. Building on the work of citeN{Barnett-FractureMechanics} the influence that anisotropy has on the fatigue response of the material is also modeled. This is accomplished through using the effective elastic stiffness tensor in the computation of crack extension force G. The resulting material model and macroscopic property calculations are the foundation for …
