Electromagnetic Simulation For Inhomogeneous Interconnect And Packaging Structures, Lijun Jiang, Barry J. Rubin, Yuan Liu, Jason D. Morsey, Alina Deustch

Electrical and Computer Engineering Faculty Research & Creative Works

The paper contains a novel mechanism for full wave electromagnetic simulation of complicated inhomogeneous structures, such as on-chip interconnects, IC packaging, antennas, and scattering objects. It uses only Equivalent Principle based EFIE instead of both EFIE and MFIE to establish the surface integral equations for practical inhomogeneous structure so that a much more simplified formulation process is needed in the EM simulation procedure. To overcome the numerical error of K operator in the formulation, a new analytical solution to the K operator for general full-wave integral equations is provided. Numerical results are demonstrated to verify the proposed algorithm. © 2007 …

James Hainlen: An Oral History Of An Exemplary Public School Orchestra Director And His Program, Rebecca E. Starr

Theses and Dissertations

Experts advise string teachers to identify and model successful string teachers and programs. However, there is a scarcity of literature that examines this subject. There is literature that examines exemplary band teachers and programs, and these works can be useful to the string teaching profession. However, string teachers ·can benefit more from literature that specifically examines exemplary string orchestra programs and teachers. The purpose of this study, therefore, was to gather information from a renowned public school string teacher about the components of his successful string orchestra program.

Building Social Trust: A Human Capital Approach, Fali Huang

Research Collection School Of Economics

Much evidence suggests individuals di¤er in their predisposition to cooperate, which is essentially a component of human capital. This paper examines the role of individual cooperative tendencies and their interactions with institutions in generating social trust; it also endogenizes cooperative tendencies using a human capital investment model. Multiple equilibria and ine¢ ciencies exist due to positive externalities. An innovative …nding is that, when institutions are more e¤ective in punishing defecting behaviors, more people invest in cooperative tendencies and hence the endogenous social trust is higher, though the equilibrium cooperative tendencies are lower. This paper provides a plausible explanation for many …

Geographic Decomposition Of Inequality In Health And Wealth: Evidence From Cambodia, Tomoki Fujii

Research Collection School Of Economics

The small-area estimation developed by Elbers, Lanjouw and Lanjouw (2002, 2003), in which a census and a survey are combined to produce the estimates of welfare measures for small geographic areas, has become a standard tool for poverty analysis in developing countries. The small-area estimates are typically plotted on a map, which are commonly called a poverty map. Poverty maps proved useful for policy analysis and formulation, and have become increasingly popular among policy-makers and researchers. In Cambodia, poverty maps have been used by various international organizations, ministries and non-governmental organizations for analyzing the poverty situations for their operation areas, …

Global Analysis Of An Expectations Augmented Evolutionary Dynamics, Angelo Antoci, Antonio Gay, Massimiliano Landi, Pier Luigi Sacco

Research Collection School Of Economics

We consider a deterministic evolutionary model where players form expectations about future play. Players are not fully rational and have expectations that change over time in response to current payoffs and feedback from the past. We provide a complete characterization of the qualitative dynamics so induced for a two strategies population game, and relate our findings to standard evolutionary dynamics and equilibrium selection when agents have rational forward looking expectations.

Nonstationary Discrete Choice: A Corrigendum And Addendum, Peter C. B. Phillips, Sainan Jin, Ling Hu

Research Collection School Of Economics

We correct the limit theory presented in an earlier paper by Hu and Phillips [2004a. Nonstationary discrete choice. Journal of Econometrics 120, 103-138] for nonstationary time series discrete choice models with multiple choices and thresholds. The new limit theory shows that, in contrast to the binary choice model with nonstationary regressors and a zero threshold where there are dual rates of convergence (n1/4 and n3/4), all parameters including the thresholds converge at the rate n3/4. The presence of nonzero thresholds therefore materially affects rates of convergence. Dual rates of convergence reappear when stationary variables are present in the system. Some …

Incidental Trends And The Power Of Panel Unit Root Tests, Hyungsik Roger Moon, Benoit Perrron, Peter C. B. Phillips

Research Collection School Of Economics

The asymptotic local power of various panel unit root tests is investigated. The (Gaussian) power envelope is obtained under homogeneous and heterogeneous alternatives. The envelope is compared with the asymptotic power functions for the pooled t-test, the Ploberger and Phillips [2002. Optimal testing for unit roots in panel data. Mimeo] test, and a point optimal test in neighborhoods of unity that are of order n-1/4T-1 and n-1/2T-1, depending on whether or not incidental trends are extracted from the panel data. In the latter case, when the alternative hypothesis is homogeneous across individuals, it is shown that the point optimal test …

Building Social Trust: A Human Capital Approach, Fali Huang

Research Collection School Of Economics

Much evidence suggests individuals differ in their predisposition to cooperate, which is essentially a component of human capital. This paper examines the role of individual cooperative tendencies and their interactions with institutions in generating social trust; it also endogenizes cooperative tendencies using a human-capital investment model. Multiple equilibria and inefficiencies exist due to positive externalities. An innovative finding is that, when institutions are more effective in punishing defecting behaviors, more people invest in cooperative tendencies and hence the endogenous social trust is higher, though the equilibrium cooperative tendencies are lower. This paper provides a plausible explanation for many empirical and …

A Consistent Characteristic Function-Based Test For Conditional Independence, Liangjun Su, Halbert White

Research Collection School Of Economics

Y is conditionally independent of Z given X if Pr{f(y|X,Z)=f(y|X)}=1 for all y on its support, where f(·|·) denotes the conditional density of Y given (X,Z) or X. This paper proposes a nonparametric test of conditional independence based on the notion that two conditional distributions are equal if and only if the corresponding conditional characteristic functions are equal. We extend the test of Su and White (2005. A Hellinger-metric nonparametric test for conditional independence. Discussion Paper, Department of Economics, UCSD) in two directions: (1) our test is less sensitive to the choice of bandwidth sequences; (2) our test has power …

Using Gis To Optimize The Design And Implementation Of The Rtk Reference Network In Abu Dhabi, Mustafa Abdulla Almusawa

Theses

Several challenging applications and construction works demand real-time measurements for positioning at the centimeter-level accuracy. This positioning accuracy can be obtained by using a Global Positioning System (GPS) roving unit and employing a single reference station (base-station) or through utilizing the service of multiple reference stations forming a Real-Time Kinematics (RTK) Reference Network.

The limitation of the single reference approach is that measurement errors are distance dependent and good accuracy can be only obtained when distances are less than 10 kms. In addition, this method requires a nearby Geodetic Control Point (GCP). Recently, RTK reference networks are widely established in …

Research Collection School Of Computing and Information Systems

Individuals differ in their abilities to use information systems (IS) effectively, with some achieving exceptional performance in IS use. Using the Repertory Grid Technique, this research identifies attributes of highly competent IS users that distinguish them from less competent users. Using the Grounded Theory approach, we identified categories and sub-categories of these attributes and used them to develop a conceptual framework to explain IS User Competency. The findings indicate that highly competent users differ from less competent users in their Personality Traits and Disposition Factors, General Cognitive Abilities, Social Skills and Tendencies, Experiential Learning Factors, Domain Knowledge of and Skills …

Tuning Tabu Search Strategies Via Visual Diagnosis, Steven Halim, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

While designing working metaheuristics can be straightforward, tuning them to solve the underlying combinatorial optimization problem well can be tricky. Several tuning methods have been proposed but they do not address the new aspect of our proposed classification of the metaheuristic tuning problem: tuning search strategies. We propose a tuning methodology based on Visual Diagnosis and a generic tool called Visualizer for Metaheuristics Development Framework(V-MDF) to address specifically the problem of tuning search (particularly Tabu Search) strategies. Under V-MDF, we propose the use of a Distance Radar visualizer where the human and computer can collaborate to diagnose the occurrence of …

Reinterpreting The Pollen Data From Dos Cabezas, Karl J. Reinhard, Vaughn M. Bryant, Sheila D. Vinton

School of Natural Resources: Faculty Publications

The published pollen analysis of the Dos Cabezas giants, Geyer et al. (2003), lists variety of purported dietary pollen types. The paper also hypothesises that the giants were poisoned with plant toxins. We have severe reservations about the pollen evidence of diet and poisoning. We suggest that the analysts made several errors in their interpretation. Firstly, some of the discovered pollen types are not prehistoric endemics to the Dos Cabezas region of coastal Peru. These include the pollen of fava beans (cultivated in the Old World), and specified species of agave and sage. We believe that some or all of …

Table Driven Prediction For Recursive Descent Ll(K) Parsers, William M. Leiserson

Theses

Programming languages are typically described in BNF or some extension of BNF, and the process of converting these descriptions into parsers is performed by parser generators. Some of the parser generators that convert LL grammars into parsers construct them to use recursive descent that gives them context during execution. The context is provided by the execution stack as the parser descends into the grammar and this is what allows the full expressiveness of LL grammars. Table driven parsers can be generated instead but restrictions are placed on the LL grammars that can be accepted. The benefit of tables is that …

Effects Of Knee Bracing On Vertical Jumping Performance In Healthy College Aged Males, Rebecca E. Rausch

All-Inclusive List of Electronic Theses and Dissertations

Knee bracing is used at all levels of athletics to prevent or support existing knee injuries; however, little research has been conducted on the effects of knee braces on athletic performance. Therefore, the purpose of this study was to examine how two different types of knee braces, semi-customizable braces and knee sleeves, affect vertical jumping performance. Subjects were nine college aged males who regularly participated in athletic activity. Subjects performed a task consisting of a drop jump from a height of 18 inches, landing in a squat position, followed immediately by a maximal vertical jump while wearing two different knee …

Spatial And Temporal Analysis Of Tornado Fatalities In The United States: 1880-2005, Walker S. Ashley

Faculty Articles, Papers, and Other Scholarship

A dataset of killer tornadoes is compiled and analyzed spatially in order to assess region-specific vulnerabilities in the United States from 1880 to 2005. Results reveal that most tornado fatalities occur in the lower–Arkansas, Tennessee, and lower–Mississippi River valleys of the southeastern United States—a region outside of traditional “tornado alley.” Analysis of variables including tornado frequency, land cover, mobile home density, population density, and nocturnal tornado probabilities demonstrates that the relative maximum of fatalities in the Deep South and minimum in the Great Plains may be due to the unique juxtaposition of both physical and social vulnerabilities. The spatial distribution …

Faculty Publications

The production of dijets in diffractive deep inelastic scattering has been measured with the ZEUS detector at HERA using an integrated luminosity of 61 pb-1. The dijet cross section has been measured for virtualities of the exchanged virtual photon, 5 < Q2 < 100 GeV2, and γ*p centre-of-mass energies, 100 < W < 250 GeV. The jets, identified using the inclusive kT algorithm in the γ*p frame, were required to have a transverse energy E* T,jet > 4 GeV and the jet with the highest transverse energy was required to have E* T,jet > 5 GeV. All jets were required to be in the pseudorapidity range -3.5

Color Space Analysis For Iris Recognition, Matthew K. Monaco

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis investigates issues related to the processing of multispectral and color infrared images of the iris. When utilizing the color bands of the electromagnetic spectrum, the eye color and the components of texture (luminosity and chromaticity) must be considered. This work examines the effect of eye color on texture-based iris recognition in both the near-IR and visible bands. A novel score level fusion algorithm for multispectral iris recognition is presented in this regard. The fusion algorithm - based on evidence that matching performance of a texture-based encoding scheme is impacted by the quality of texture within the original image …

Design And Real-Time Control Of Shipboard Power System Testbed, Pradeep Pant

Graduate Theses, Dissertations, and Problem Reports (ETD)

The objective of this thesis is to design and test a small scale testbed for the all-electric shipboard power distribution system. Shipboard power system is increasingly becoming more reconfigurable, and multi-agent systems are developed to automate routine operation and emergency reconfiguration. Underlying algorithms of these systems have been verified using software simulation tools. However, these simulators run in soft realtime by using simple mathematical models to represent the physical system. These models do not incorporate every aspect of the physical system. A testbed provides a cost effective physical environment to verify these algorithms and control techniques in the real world. …

Modeling Sediment Movement In Forested Watersheds Using Hill-Slope Attributes, Gregory W. Hamons

Graduate Theses, Dissertations, and Problem Reports (ETD)

The amount of sediment delivered to stream channels and the determination of the topographical attributes responsible for the origination and transfer of sediment were investigated in a central Appalachian mixed hardwood forest from 2002 through 2005. Two study watersheds were chosen within the Indian Run watershed in north central West Virginia. One remained undisturbed (control) and the other underwent road construction and tree harvesting operations (treatment). Sediment samples were collected from silt fences which were installed along both sides of the stream channels in both watersheds to ensure all sediment material delivered from adjacent hill-slopes was captured and collected. Sediment …

L5 And L7 Recalibration Procedure, Sai Kiran Undrala

Masters Theses & Doctoral Dissertations

The Landsat-5 (LS) satellite was launched on March 01, 1984 with thematic Mapper (TM) and has collected data for 23 years. Over this time, the detectors have aged, and its radiometric characteristics have changed little from the day it launched. The calibration procedures and parameters have also changed with time. Revised radiometric calibrations have improved the radiometric accuracy of recently processed data. A procedure has been developed to give users the ability to recalibrate their existing Level 1 (Ll) products without having to purchase and reprocess data from the U.S. Geological Survey (USGS). The accuracy of the recalibration is dependent …
