Sequential And Parallel Discrete Event Simulation On Computer Communication Networks, Tao Zhou

Masters Theses

This thesis presents the discrete event simulation technique on the network design, focusing on the methodology, modeling and implementation. The developed technique is suitable for the analysis of any store-and-forward computer communication networks with any level of complexity. The proposed generic simulation model can be used to test the architectures and protocols of existing networks and networks being designed. In implementation of the sequential discrete event simulation, an object-oriented programming strategy is applied to the network simulation using the C++ language. The parallel discrete event simulation is introduced to solve the problem of long time execution of the sequential simulation …

Synthesis Of Organometallic Polymers, Po-Chang Chiang

Masters Theses

By the middle of the nineteenth century, organic chemists found high molecular weight compounds as by-products of some of their experiments. These compounds were thought of as products of a failed reaction. It was not until sixty years ago that the first polymers were deliberately synthesized. Today polymers are used in almost every facet of life and they are becoming more important with each passing day.

This research project focused on synthesizing conducting organometallic polymers. By linking aromatic rings with transition metals, the resultant polymers should have good electrical conductivity because of the interaction of (a) the p electrons on …

Double Differential Cross Sections For State-Selective Electron Capture By Low-Energy Ar4+ And Ar5+ Ions From He And Ar, Serefettin Yaltkaya

Masters Theses

Doubly differential cross sections, in angle and energy, for state-selective single-electron capture from He and Ar by Ar⁴⁺ and Ar⁵⁺ ions have been studied experimentally at laboratory impact energies of 25q, 50q, and lOOq eV (q = 4 and 5, where q is the ion charge state) and at laboratory scattering angles between 0° and 5.5°, by means of translational energy spectroscopy. The translational energy-gain spectra show that only a few final states are selectively populated. Final-state transition probabilities were found to depend strongly on the charge state of the projectile ion and the ionization potential of the …

Single And Double Ionization Of Helium By Highly Charged Sulfur Ions, Karen M. Lifrieri

Masters Theses

Single and double ionization of helium by highly charged sulfur projectiles is investigated over an energy range of 0.16 to 1.6 MeV/u. Absolute cross sections for the processes of pure ionization, ionization associated with single capture, and ionization associated with single loss by S^6,13+ projectiles were experimentally determined and compared with previous results and theories. Ratios of double-tosingle ionization for each outgoing projectile charge state were also determined and compared with theory. The pure ionization ratios for S⁶⁺ at the highest energies investigated show the q²/E dependence predicted by Knudsen et al. (1984). For S^{13+ …}

Performance Prediction In Track And Field, Ted James Dabbs

Masters Theses

The study investigated the degree to which predicting performance in track and field relates to individual performances of track athletes. Predictive scores were determined for 26 male and 14 female athletes using prediction equations and test procedures developed by Henson, Turner, and Lacourse (1989a; 1989b). Predictive scores were compared to athletes' individual event point scores published in International Amateur Athletic Federation (IAAF) men's and women's multi-event scoring tables ("Scoring Table for Men's," 1962; "Scoring Table for Women's," 1971).

Each subject's height, weight and age were recorded as well as performances on the following tests: vertical jump, standing long jump, five …

Algorithms For Incomplete Hypercubes, Venkata K. Prabhala

Masters Theses

Networked multiprocessing architectures for parallel com putation offer an alternative to high cost supercomputing. Recently hypercube has emerged as the most versatile architecture for parallel com putations. However, the number of nodes m in a hypercube is a power of 2, 2^d, where d is the dimension of the hypercube. In practice, it m ay not be possible to have a complete hypercube because the cost of upgradation is proportional to the num ber of nodes. Incomplete and Composite hypercubes help remove the exponential node(and hence cost) constraint.

In this thesis we establish the equality of m-node …

On Planar Routing Of Multi-Terminal Nets In Vlsi Physical Design, Jahangir A. Hashmi

Masters Theses

In this thesis, we study two problems related to the physical design of VLSI circuits. One problem is related to the VLSI global routing and the other is related to the detailed routing in a bounded region.

We consider the routing of multiple multi-terminal nets on a single layer. We suggest a new approach for this problem. Our approach is based on simultaneously finding a forest of k non-intersecting spanning trees. We present an O(n^3) algorithm for finding two spanning trees corresponding to two nets on a single layer.

We also study the problem of finding a minimum Steiner tree …

The Application Of A Statistical Trend Analysis Program To Ground-Water Quality Monitoring Data From Eight Western Michigan Solid Waste Landfills, Amy Decosta Lachance

Masters Theses

A statistical analysis and interpretation of ground-water chemistry data from eight landfills in Western Michigan was performed. Data were collected over approximately the past ten years, pursuant to the requirements of Michigan's Solid Waste Management Act. A statistical regression model was used to reduce the data to identifiable trends and estimated magnitudes. These results were analyzed with respect to each landfill's characteristics and hydrogeological setting. Comparisons were made concerning the landfills' relative potential for environmental harm. Also, the effectiveness and applicability of this model to the analysis of ground-water monitoring data was assessed.

It was concluded that this analysis and …

Graph Theory Based Routing Algorithms, Bo Wu

Masters Theses

In this thesis, we study two VLSI layout problems.

We investigate the Minimum-Bend Single Row Routing Problem in which the objective function is to minimize the number of doglegs (or blends) per net. Our approach uses a graph theoretic representation in which an instance of the Single Row Routing Problem is represented by three graphs, an overlap graph, a containment graph and an interval graph. Using this graph representation, we develop three algorithms for minimum-bend single row routing problem.

We present a three-layer over-the-cell router (ICR-3) for the standard cell design style based on a new cell model which assumes …

Perestroika From Below: Civil Society And Informal Associations In The Soviet Union, Jerry James Sheehan

Masters Theses

During the 1980's the Soviet Union underwent a decade of dramatic change. The study of these changes initiated by the Gorbachev government has focused primarily on the reforms initiated by the state- perestroika from above. However, by the mid 1980's it was apparent that the state was not so much reforming society as society was drastically altering the state. Some analysts at this time began to shift to examining reforms at the grassroots level- perestroika from below.

This thesis is an examination of these perestroika from below reforms. The thesis seeks to asses the usefulness of the civil society model …

Butenolide Synthesis Via Cation-Initiated Ring Expansion/Elimination Of Β-Lactones, Jianhua Huang

Masters Theses

An area of recent research in the Black research group is an exploration of the potential of cation-initiated β-lactone ring expansions, accompanied by the elimination of a proton or other electrofuge, as a protocol for the synthesis of multisubstituted butenolides.

Γ-Bromo β-lactones were prepared via bromolactonization of the appropriate β,Γ-unsaturated acids under basic conditions. The nucleofugal bromine atom on the Γ-carbon was then employed to effect carbocation formation adjacent to the lactone ring oxygen atom; the most efficacious reagent combination was found to be silver nitrate in refluxing acetic acid. Generation of this cation initiated a migration of the β-lactone …

The Effects Of Beaver-Created Wetlands On Surface Water Quality Of Streams And Rivers In Dupage County, Illinois, Brian Conklin

Masters Theses

Dam construction by beavers creates wetlands which have the potential to improve water quality, especially in areas near urban centers. However, beaver dams may also cause flooding problems which can result in the removal of the beaver(s) and the destruction of their dam. A further understanding of how beaver-created wetlands affect water quality will provide additional data which can be utilized in beaver management decisions.

In this study, 41 chemical parameters were examined from water taken above and below beaver-created wetlands that existed in DuPage County, Illinois between May and September 1991. This study was designed to examine the effects …

New Reagents And Reactions For Desulfurization Of Coal, Shan Wang

Masters Theses

Searching for new reagents and reactions for pre-combustion desulfurization of coal was the goal of this work. In this study, modifications of mild desulfurization reactions, which were found to work with organosulfur model compounds, have been investigated systemetically for improvements in sulfur removal and reduction of reagent cost. The screening of reagents and new reactions utilized substituted thiophenes plus aryl sulfides as the initial models for organosulfur compounds in coal. Tetrahydrofuran extracts of Illinois Basin Coals were also used as second generation targets for desulfurization reactions.

Dibenzothiophene was converted to biphenyl using potassium metal/tetrahydrofuran without the addition of electron transfer …

Adopting An Eight Period Day Schedule: An Analysis Of The Merits For Oakland Community Unit School District #5, Norman L. Tracy

Masters Theses

In coping with financial problems and changing demands on students' course selections, it has become increasingly more difficult to provide secondary school students with the best education possible. This seems to be especially true for the smaller school districts. Many small school districts have reduced their staffs to the "bare bones" due to budget cuts. Such reductions have often resulted in fewer course offerings and a reduced number of section offerings for required classes. When this problem was coupled with the Illinois Board of Higher Education's increased college entrance requirements that high school students must complete, the common result was …
