Preserd - Privacy Ensured Service Discovery In Mobile Peer-To-Peer Environment, Santhosh Muthyapu

Masters Theses

"In mobile peer-to-peer networks many service discovery protocols have been proposed. Most of these protocols disregard the exposure of the participating peers' privacy details, although they consider the security issues. In these methods, the participating peers must provide their identities, during the service discovery process, to be authorized to utilize the service. However, a peer might not be willing to reveal its identity until it identifies the service providing peer. So these peers face a problem; should the requesting peer or the service providing peer reveal the identity first, and hence, this is similar to the chicken-and-egg problem. The protocol …

The Asymptotic Iteration Method For The Eigenenergies Of The Complex Potential V(X) = \Gamma X^4 + I \Beta X^3 + I \Alpha X, Abdallah Jamiel Sous

Turkish Journal of Physics

Recently, three complex potentials V(x) = i x^3,V(x) = i x^3 + i \alpha x, and V(x) = x^4 + i \alpha x have been studied in the literature. Here, we combine these potentials in one. With the aid of the asymptotic iteration method we have numerically calculated the eigenenergies of the new complex potential. The obtained numerical results are compared with those obtained by using the WKB, EMM, and MRF methods and found to be in an excellent agreement. We discuss how an adjustable parameter \zeta can help to improve our results.

Investigation Of The Ground State Features Of Some Excotic Nuclei By Using Effective Skyrme Interaction, Hüseyi̇n Ayteki̇n, Eyyüp Tel, Ridvan Baldik

Turkish Journal of Physics

Nuclear many-body system is usually described through a mean-field built upon a nucleon-nucleon effective interaction. This interaction has been developed over the years for both stable and unstable nuclei as precise spectroscopic data has been built up. In this study, the proton and neutron densities, charge densities, root mean square (rms) nuclear charge radii, rms nuclear mass radii, rms nuclear proton and neutron radii, and neutron skin thickness were calculated for the neutron-rich Ni, Kr and Sn isotopes by the Hartree-Fock method with an effective Skyrme force based on nucleon-nucleon interactions known as SI, SIII, SVI, T3, SKM and SKM^*. …

Computational Study Of Vibrational Dynamics Of Binary Mg_{0.70}Zn_{0.30} Metallic Glass By A Pseudopotential Theory, Aditya M. Vora

Turkish Journal of Physics

The vibrational dynamics of Mg_{70}Zn_{30} metallic glass has been studied at room temperature in terms of phonon eigen-frequencies of longitudinal and transverse modes employing three different approaches proposed by Hubbard-Beeby (HB), Takeno-Goda (TG) and Bhatia-Singh (BS). The well-recognized model potential is employed successfully to explain electron-ion interaction in the metallic glass; instead of using experimental values of the pair correlation function g(r), which is generated from the computed pair potential. The present findings of phonon dispersion curve are found in fair agreement with available theoretical as well as experimental data. The thermodynamic properties obtained by HB and TG approaches are …

Methodology And Process To Accompany A Virtual Geotechnical Database For The St. Louis Metropolitan Area, Katherine Leigh Onstad

Masters Theses

"The St. Louis metropolitan (STL) area, which spans Missouri and Illinois, currently has no overarching organization of geospatial data (geodata). The two states have their own geodata, using their own individual standards. The development of a virtual geotechnical database (VGDB) encompassing the entire STL area on both sides of the Mississippi River is a solution to the data sharing and standardization problem of this area. The VGDB integrates geodata from disparate sources into a geographic information systems (GIS) database accessible via the internet. The creation of the STL area VGDB consisted of three parts: 1) compiling the geodata; 2) formatting …

A Winning Proposition: The Economic Impact Of Successful Nfl Franchises, Christian M. End, Michael C. Davis

Economics Faculty Research & Creative Works

Research has demonstrated that a Super Bowl victory increases the personal income of the individuals in the metropolitan area from which the winning teams come (Coates & Humphreys, 2002). We argue that the economic benefits should extend beyond just the championship team's city to the cities of teams who experience seasonal success and thus the winning percentages of NFL teams were included in our model. when controlling for sources of bias, winning percentage of the local professional football team had a significant positive effect on real per capita personal income. Explanations for these conclusions are offered from a psychological perspective.

Addressing Nonlinear Combustion Instabilities In Highly Dilute Spark Ignition Engine Operation, Brian C. Kaul

Doctoral Dissertations

"Dilute operation is a promising approach for increasing spark-ignition engine efficiency, in the form of either lean burn (air dilution) or EGR (inert dilution). High levels of charge dilution, however, lead to cyclic variability that is largely deterministic in nature. The determinism and nonlinear nature of the system indicate that it should be possible to reduce the cycle-to-cycle variations by implementing an electronic controller. Several needs arise when considering the development of such a controller. Three topics of interest are covered herein. First, a method of analysis for nonlinear dynamical systems is applied to engine data in order to estimate …

Modeling, Analysis And Experimentation For Building Ice Parts With Supports Using Rapid Freeze Prototyping, Frances D. Bryant

Doctoral Dissertations

"Rapid Freeze Prototyping (RFP) is a freeform fabrication method that freezes water droplets into ice in a layer-by-layer manner to additively create a 3-dimensional part. Each layer of a geometry is deposited and allowed to freeze before the next layer is added. Ice parts produced by RFP can be used in investment casting to replace wax patterns and in other applications which may benefit from the unconventional method of using ice as a pattern or mold. More recently, a sacrificial support material has been incorporated into RFP so that over-hung areas and complex geometries can be fabricated. The research presented …

Design And Evaluation Of A Virtual Reality Training System For New Underground Rockbolters, David Nutakor

Doctoral Dissertations

"The need for development of better training techniques for underground rock bolters is signified by the fact that a large number of experienced miners (Baby Boomers) will be retiring soon. This means that there will be very little interface time between the new miners and the experienced miners, which could have been used for training the new inexperienced miners. A new generation of workers (Nexters), who have grown up with computers and video games will replace the Baby Boomers, and the most efficient way to introduce them to the safety and health issues of the mining industry is to use …

Energy Efficient Clustering And Secure Data Aggregation In Wireless Sensor Networks, Julia Albath

Doctoral Dissertations

"Communication consumes the majority of a wireless sensor network's limited energy. There are several ways to reduce the communication cost. Two approaches used in this work are clustering and in-network aggregation. The choice of a cluster head within each cluster is important because cluster heads use additional energy for their responsibilities and that burden needs to be carefully distributed. We introduce the energy constrained minimum dominating set (ECDS) to model the problem of optimally choosing cluster heads in the presence of energy constraints. We show its applicability to sensor networks and give an approximation algorithm of O(log n) for solving …

Predicting And Reducing Warranty Costs By Considering Customer Expectation And Product Performance, Naresh Kumar Sharma

Doctoral Dissertations

"This dissertation develops from quality loss function to warranty loss function in which customer expectation is also considered to be a variable. First, Taguchi's quality loss function for the larger-the-better case, which is different from the smaller-the better and nominal-the-best cases, has been assimilated into the other two by introducing a term called the target-mean ratio. Further topics addressed include the implications of a finite target on the classification of LTB characteristics, a new concept of a "Complementary Characteristic", operating window, complexity, and SN ratio based on complexity. A warranty is a buyer's confidence owing to the seller's assurance to …

System And Ic Level Analysis Of Electrostatic Discharge (Esd) And Electrical Fast Transient (Eft) Immunity And Associated Coupling Mechanisms, Jayong Koo

Doctoral Dissertations

"The exposure of electronic circuits to lightning, electrostatic discharge (ESD), electrical fast transients (EFT) or sine wave signals can reveal RF immunity problems. Typical problems include temporary malfunctions or permanent damage of integrated circuits (ICs). In an effort to reproduce those disturbances, a series of electromagnetic compatibility standards has been developed. However, a complete understanding of the root cause of the immunity problems has yet to be established. This dissertation discusses immunity problems in three papers, starting at the system level, via the coupling path into the IC"--Abstract, page iv.

Mechanics Of Dump Truck Vibrations In High-Impact Shovel Loading Operations, Nassib Aouad

Doctoral Dissertations

"The deployment of large machinery for low cost, bulk surface mine production operations has resulted in high-impact shovel loading operations (HISLO). In extreme cases, shovels load large dump trucks with 100-ton (or more) passes generating high-impact forces under gravity. HISLO generates high-frequency shockwaves that cause severe truck vibrations exposing operators to whole body vibrations (WBV). This WBV levels may exceed the recommended International Standards Organization (ISO) limits resulting in longterm lower-back disorders and other health problems. There is a need for fundamental and applied research to determine HISLO vibration levels for heavy mining machinery, their comparisons to ISO 2631 limits …

Scottish Common Sense And Nineteenth-Century American Law: A Critical Appraisal, John Mikhail

Georgetown Law Faculty Publications and Other Works

One overriding concern I have with Susanna Blumenthal's insightful and stimulating article, "The Mind of a Moral Agent: Scottish Common Sense and the Problem of Responsibility in Nineteenth-Century American Law," is whether there is anything sufficiently distinctive about Scottish Common Sense philosophy that justifies the role Blumenthal ascribes to it. One could probably replace "Common Sense philosophy" in Blumenthal's formulation with something as diffuse as "The Enlightenment," or even "Western jurisprudence," without significantly altering its import, because the assumption that rational and moral faculties are innate and universal is common to most writers in these traditions. There are subtle differences …
