Between Pets And People: The Importance Of Animal Companionship, Alan M. Beck, Aaron Katcher

New Directions in the Human-Animal Bond

Pets play a greater role in our emotional and physical health than ever before, says the Purdue University professor who is co-author of his revised edition of Between Pets and People: The Importance of Animal Companionship. The book offers conclusive evidence from the two foremost researchers in the field, Alan M. Beck and Aaron H. Katcher, that animals have a significant influence on human life and health. Dealing with such varied topics as pet ownership and gender differences, the pet’s freedom from social taboos, and pets’ taking on roles of family members, the authors show that animal companionship affects, …

Benchmarking And Verification Of Bipolar Junction Transistor Tcad Simulation Programs, Carrie Ann Niemiec, Mark S. Lundstrom

Department of Electrical and Computer Engineering Technical Reports

This thesis contains the results from a benchmarking study, which involves comparing different device modeling approaches. After discussing the pflilosophical importance of accuracy and truth in science with respect to modeling, modern day simulation methods are discussed and a methodology defined. The modeling approaches compared are the drift-diffusion method, which is most commonly utilized currently, the hydrodynamic/energy transport method, which has greater rigor than drift-difision but has some convergence problems, and the scattering matrix approach, which fully solves the Boltzmann Transport Equation. The scattering matrix approach is used as the computational benchmark because it is the most rigorous and accurate …

Automatic Gradient Threshold Determination For Edge Detection Using A Statistical Model A Description Of The Model And Comparison Of Algorithms, Peter V. Henstock,, David M. Chelberg

Department of Electrical and Computer Engineering Technical Reports

In the enhancement/thresholding method of edge detection, the gradient values of pixels exceeding a certain threshold are designated as edge pixels. However, selecting a threshold has commonly been performed through ad hoc measures. This paper describes a method for automatically selecting a threshold using a 5-parameter model. The model is based on the weighted sum of two gamma density functions corresponding to edge and ncln-edge pixels. A variety of statistical and fitting methods for finding the model parameters were evaluated by comparing their computed thresholds to perceptual thresholds determined by subjects for 16 different images. The performance of the model …

An Introduction To Systematic Sensitivity Analysis Via Gaussian Quadrature, Channing Arndt

GTAP Technical Papers Archive

Economists recognize that results from simulation models are dependent, sometimes highly dependent, on values employed for critical exogenous variables.

To account for this, analysts sometimes conduct sensitivity analysis with respect to key exogenous variables.

This paper presents a practical approach for conducting systematic sensitivity analysis, called Gaussian quadrature.

The approach views key exogenous variables as random variables with associated distributions. It produces estimates of means and standard deviations of model results while requiring a limited number of solves of the model. Under mild conditions, all of which hold with respect to the GTAP model, there is strong reason to believe …

Liberalization And Capital Accumulation In The Gtap Model, Joseph Francois, Brad Mcdonald

GTAP Technical Papers Archive

This paper explores trade policy and investment linkages in the GTAP model. This is done under alternative steady-state closure rules linking trade to consumption, production, and investment, and emphasizing the general equilibrium nature of capital accumulation mechanisms.

When policy shocks are capital friendly, induced investment may be greater than suggested by current savings rates. As a result, multiplier-type analysis can be very misleading.

The importance and direction of this magnification hinges critically on the sensitivity of savings rates with respect to real returns. As illustration, we offer a numerical assessment of the Uruguay Round, highlighting such linkages.

Effect Of Value Based Software Engineering On Development Projects, Raymond Paul, Mageda A. Sharafeddin, Y. Shinagawa, Arif Ghafoor

Department of Electrical and Computer Engineering Technical Reports

Previous models of software development projects have failed to represent people productivity accurately. In this paper, we present a model characterized by realistic productivity curves and flexibility in choosing resource factors in a software engineering project. A two-mode mathematical model similar to PutnamNorden model js presented. The proposed model enhances the capability of engineering management users to make corrective actions when appropriate. It is extremely beneficial to detect problems and provide corrective actions since they are in many cases crucial to the successful project software engineering hiring and/or acquisition management planning to use the software product.

Channel Carrying: A Novel Handoff Scheme For Mobile Cellular Networks, Junyi Li, Ness Shroff, Edwin K.P. Chong

Department of Electrical and Computer Engineering Technical Reports

We present a new scheme that addresses the call handoff problem in mobile cellular networks. Efficiently solving the handoff problem is important for guaranteeing Quality of Service (QoS) to already admitted calls in the network. Our scheme is based on a new concept called channel car,rying: when a mobile user moves from one cell to another, under certain mobility conditions, .the user is allowed to carry its current channel into the new cell. We propose a new channel assignment scheme to ensure that this movement of channels will not lead to any extra co-channel interference or channel locking. In our …

Image Compression And Representation Using Wavelets, Shankar Moni, R. L. Kashyap

Department of Electrical and Computer Engineering Technical Reports

The focus of this research is to explore the structure present in the wavelet decomposition of natural images and use this structure for image compression and representation. We first show empirically that the wavelet coefficients of a natural image, when sorted by magnitude, lie almost exactly on a curve of the form $. This, in turn, helps us to demonstrate that natural images may exhibit self-similarity in the wavelet domain, although no such property may be apparent in the pixel domain. In order to predict which scale-space positions may have large wavelet coefficients, we define a data structure called a …

Suboptimal Target Tracking In Clutter Using A Generalized Probabilistic Data Association Algorithm, Wai Ying Kan, James V. Krogmeier

Department of Electrical and Computer Engineering Technical Reports

Simple tracking algorithms based upon nearest neighbor filtering do not correctly consider measurement origin uncertainty and, therefore, fail to perform well in situations of high target density and clutter. The optimal tracking algorithm for commonly used targetclutter models computes the posterior density of the target state conditioned on the past history of' observations. This posterior density is a Gaussian mixture with the number of terms equal to the number of possible ways to associate observations and targets. Though a recursive algorithm may be developed for the optimal estimator, it requires exponentially growing rlemory and computation and is, therefore, unimplementable. In …
