A Mixed-Form Fast Multipole Algorithm, Li (Lijun) Jun Jiang, Weng Cho Chew

Electrical and Computer Engineering Faculty Research & Creative Works

The fast multipole algorithm manifests in two very different forms at low frequencies and at mid frequencies. Each can operate in their respective regimes, but are not tenable in the other regimes. The paper reports on a way to factorize the Green's function for fast algorithm using a mixed form. The low-frequency fast multipole algorithm (LF-FMA) will be used at low frequencies or the long-wavelength regime, and the multilevel fast multipole algorithm (MLFMA) will be used for the mid frequencies or the shorter-wavelength regime. For object modeling where both long-wavelength and wave physics are important, we propose a mixed-form fast …

Ductile Regime Nano-Machining Of Silicon Carbide, Biswarup Bhattacharya

Masters Theses

This thesis describes experimental work carried out to study the ability to ductile . single point diamond turn both polycrystal Silicon Carbide (SiC) and chemically vapor deposited (CVD) SiC. A Precitech diamond turning machine was used for ductile regime machining of polycrystal SiC at depths of 10 and 25 nm. The possibility of machining SiC in the ductile mode was substantiated by post process analysis of the chips collected during machining and the surface profiles. The force data obtained during machining was recorded and compared later with the different depth of cuts. An investigation into the ability to single point …

Cloning, Overexpression, Purification And Characterization On N-Terminal Metal Binding Domains 5 And 6 Of Wilsons Disease Protein, David Achila

Masters Theses

Wilsons disease is an autosomal recessive disorder of copper metabolism which results from mutations in the gene encoding for Wilson disease protein (WDP). The cytosolic N-terminus of WDP comprises six metal binding domains each containing a conserved metal binding motif, GMXCXXC. The contribution of these metal binding domains to copper homeostasis is poorly understood. We have cloned, expressed and purified residues 485 to 633 corresponding to N-terminal metal-binding domains 5 and 6 of WDP (WD5-6). Two of the 3 disease causing mutations in the N-terminal metal binding domains of WDP occur one in each of these domains and the two …

Evaluation Of Mechanical Properties Of Recycled Aggregate Concrete, Sajjad Ali Khan

Masters Theses

The maintenance and repair work in the civil engineering infrastructures develops the production of huge wastes which causes the growth of waste piles, additional costs in construction projects and some environmental problems. If this waste is recycled and used again in construction projects, it will help to overcome the problems discussed earlier. Moreover, if natural aggregates are supplemented by recycled aggregate, it will preserve the natural resources and also put a pause in the deterioration of natural landscape.

This thesis addresses the importance of using recycled aggregate in concrete structures. Its practical feasibility in construction projects is studied in light …

The Stress Management Self-Efficacy Inventory (Smsei): Development And Initial Psychometrics, Kristin Higgins

Graduate Theses and Dissertations

The primary purpose of the current study was to develop, pilot, and establish the initial psychometrics of the Stress Management Self-Efficacy Inventory (SMSEI). Once developed and positive psychometrics established, middle school counselors and other mental health professionals can use the SMSEI to identify children who lack self-efficacy in the area of stress management. Once adolescents are identified as having low stress management self-efficacy, this measure can also aid professionals in creating programs and interventions. The SMSEI measures how well adolescents believe they can manage their stress as well as measures specific areas or management techniques that a child believes they …

Improving The Quality Of Conceptual Modeling Using Cognitive Mapping Techniques, Keng Siau, X. Tan

Research Collection School Of Computing and Information Systems

Conceptual modeling involves the understanding and communication between system analysts and end-users. Many factors may affect the quality of conceptual modeling processes as well as the models per se. Human cognition plays a pivotal role in understanding these factors and cognitive mapping techniques are effective tools to elicit and represent human cognition. In this paper, we look at the use of cognitive mapping techniques to improve the quality of conceptual modeling. We review frameworks on quality in conceptual modeling and examine the role of human cognition in conceptual modeling. The paper also discusses how human cognition is related to quality …

Tailored Watermarking Schemes For Authentication Of Electronic Clinical Atlases, Feng Bao, Robert H. Deng, Beng-Chin Ooi, Yanjiang Yang

Research Collection School Of Computing and Information Systems

It is accepted that digital watermarking is quite relevant in medical imaging. However, due to the special nature of clinical practice, it is often required that watermarking not introduce irreversible distortions to medical images. The electronic clinical atlas has such a need of "lossless" watermarking. We present two tailored reversible watermarking schemes for the clinical atlas by exploiting its inherent characteristics. We have implemented the schemes and our experimental results look very promising.

Integration Of Probabilistic Graphic Models For Decision Support, Jiang C., Poh K., Tze-Yun Leong

Research Collection School Of Computing and Information Systems

It is a frequently encountered problem that new knowledge arrived when making decisions in a dynamic world. Usually, domain experts cannot afford enough time and knowledge to effectively assess and combine both qualitative and quantitative information in these models. Existing approaches can solve only one of two tasks instead of both. We propose a four-step algorithm to integrate multiple probabilistic graphic models, which can effectively update existing models with newly acquired models. In this algorithm, the qualitative part of model integration is performed first, followed by the quantitative combination. We illustrate our method with an example of combining three models. …

Aesthetics And Audiovisual Metaphors In Media Perception, Kathrin Fahlenbrach

CLCWeb: Comparative Literature and Culture

In her paper, "Aesthetics and Audiovisual Metaphors in Media Perception," Kathrin Fahlenbrach presents a model of audiovisual analysis where focus is on audiovisual aesthetics perceived physically and affectively. Fahlenbrach starts out from the assumption that image and sound are inseparable in audiovisual media and must be treated as a unit, a "synchresis" (Chion). Fahlenbrach proposes that only this premise is able to cover the pre-consciously perceived elements sufficiently, namely the sensorial and affective structures of audiovisual aesthetics. Fahlenbrach articulates some aspects for an audiovisual aesthetics that concentrate on the interfaces between audiovisual perception and audiovisual design and employs to this …

An Analysis Of Websites Of Bi-National Heterosexual Couples, Sadashivam Rao

CLCWeb: Comparative Literature and Culture

In his paper "An Analysis of Websites of Bi-national Heterosexual Couples," Sadashivam Rao discusses the design of world wide web homepages of bi-national couples. Rao shows how such websites become locations of the re-invention of notions of culture, generating a particular practice of representation, namely that of "hyphenating." Rao contends that the subjects of personal homepages enter the domain of the internet as entities already embedded in many other domains of discourse such as those of nationalism, culture, and media. Further, Rao proposes that this specific genre of websites reflects traces of these discourses. Of course, in the process of …

Neutrosophic Methods In General Relativity, Florentin Smarandache, Dmitri Rabounski, Larissa Borissova

Branch Mathematics and Statistics Faculty and Staff Publications

In this work the authors apply concepts of Neutrosophic Logic to the General Theory of Relativity to obtain a generalisation of Einstein’s fourdimensional pseudo-Riemannian differentiable manifold in terms of Smarandache Geometry (Smarandache manifolds), by which new classes of relativistic particles and non-quantum teleportation are developed. Fundamental features of Neutrosophic Logic are its denial of the Law of Excluded Middle, and open (or estimated) levels of truth, falsity and indeterminancy. Both Neutrosophic Logic and Smarandache Geometry were invented some years ago by one of the authors (F. Smarandache). The application of these purely mathematical theories to General Relativity reveals hitherto unknown …

Multivalued Logic, Neutrosophy And Schrodinger Equation, Florentin Smarandache, Victor Christianto

Branch Mathematics and Statistics Faculty and Staff Publications

This book was intended to discuss some paradoxes in Quantum Mechanics from the viewpoint of Multi-Valued-logic pioneered by Lukasiewicz, and a recent concept Neutrosophic Logic. Essentially, this new concept offers new insights on the idea of ‘identity’, which too often it has been accepted as given. Neutrosophy itself was developed in attempt to generalize Fuzzy-Logic introduced by L. Zadeh. While some aspects of theoretical foundations of logic are discussed, this book is not intended solely for pure mathematicians, but instead for physicists in the hope that some of ideas presented herein will be found useful. The book is motivated by …

Removal Of Heavy Metals From Aqueous Solutions Using Local Adsorbents, Moza S. Al-Sharyani

Theses

The recent rapid increase in industrialization activities contributed to most of aquatic pollution problems. Among aquatic pollutants, heavy metals, such as zinc, lead, cadmium, and copper have gained relatively more significance in view of their persistence and toxicity. Due to their health and toxicological effects, environmental agencies and authorities have set strict regulations to maintain the limit of heavy metals in wastewater below the maximum acceptable concentration levels.

The technical feasibility of using raw date pits and different activated carbons prepared from date pits by air and acid activation as low cost local adsorbents for the removal of different heavy …

The Opacity Of Spiral Galaxy Disks. Vi. Extinction, Stellar Light And Color., Benne W. Holwerda, R. A. Gonzalez, P. C. Van Der Kruit, R. J. Allen

Faculty and Staff Scholarship

In this paper we explore the relation between dust extinction and stellar light distribution in disks of spiral galaxies. Extinction influences our dynamical and photometric perception of disks, since it can distort our measurement of the contribution of the stellar component. To characterize the total extinction by a foreground disk, González et al. (1998, ApJ, 506, 152) proposed the "Synthetic Field Method" (SFM), which uses the calibrated number of distant galaxies seen through the foreground disk as a direct indication of extinction. The method is described in González et al. (1998, ApJ, 506, 152) and Holwerda et al. (2005a, AJ, …

The Opacity Of Spiral Galaxy Disks Vii. The Accuracy Of Galaxy Counts As An Extinction Probe., Benne W. Holwerda, R. A. Gonzalez, Ronald J. Allen, P. C. Van Der Kruit

Faculty and Staff Scholarship

The "Synthetic Field Method" (SFM) was introduced by González et al. (1998, ApJ, 506, 152) to calibrate numbers of distant galaxies as a probe of extinction in a foreground spiral disk. González et al. (2003, AJ, 125, 1182) studied the effect of the foreground disk on these numbers using simulations of current and future instruments for fields in the LMC, M 31 and NGC 4536, a galaxy in Virgo. They concluded that: (1) the brighter centers of disks were unsuitable; (2) the granularity of the disk at a fixed surface brightness is the limiting factor in the detection of distant …

The Opacity Of Spiral Galaxy Disks. V. Dust Opacity, Hi Distributions And Sub-Mm Emission., Benne W. Holwerda, R. A. Gonzalez, Ronald J. Allen, P. C. Van Der Kruit

Faculty and Staff Scholarship

The opacity of spiral galaxy disks, from counts of distant galaxies, is compared to HI column densities. The opacity measurements are calibrated using the “Synthetic Field Method” from González et al. (1998, ApJ, 506, 152), Holwerda et al. (2005a, AJ, 129, 1381). When compared for individual disks, the HI column density and dust opacity do not seem to be correlated as HI and opacity follow different radial profiles. To improve statistics, an average radial opacity profile is compared to an average HI profile. Compared to dust-to-HI estimates from the literature, more extinction is found in this profile. This difference may …

Fun And Friendship In The Natural World: The Impact Of Oregon 4-H Residential Camping Programs On Girl And Boy Campers, Mary E. Arnold, Virginia D. Bourdeau, Janet Nagele

Journal of Extension

This article presents the results of a multi-site evaluation of Oregon's 4-H Camps. The evaluation assessed 3 main areas: 1) personal growth, 2) life skill development, and 3) camper satisfaction. Questionnaires were administered at the end of each camp, with the data aggregated and analyzed across camps. Results revealed significant changes in personal growth and the development of selected life skills. Results also indicated that the campers enjoyed camp and their camp counselors. The results are confirming of what we know about the impact of camp and are important for sustaining investments currently made in camp programs.
