Solving the Inverse Kinematic Robotics Problem: A Comparison Study of the Denavit-Hartenberg Matrix and Groebner Basis Theory
(2007-08-15)
The aim is to analyze two very di®erent methods for solving the inverse kinematic
robotics problem. The ¯rst method, called the Engineering Approach, uses the Denavit-
Hartenberg Matrix, and the second method, called the ...
Some Geometry of Symmetrized Tensor Spaces
(2014-05-01)
In this paper we investigate the geometry of symmetrized tensor spaces using a construct known as a coset space. We find that, for a group G, certain pairings of subgroups and irreducible characters give rise to ...
Some Like it Hot: Fire and Legume Germination in the Longleaf Pine Ecosystem
(2011-03-29)
Fire is a globally distributed disturbance and is important for structuring and maintaining the diversity of many frequently burned ecosystems. Competitive relationships and vegetation patterns may be affected by fire’s ...
Some Necessary Conditions for List Colorability of Graphs and a Conjecture on Completing Partial Latin Squares
(2008-12-15)
Let C be an infinite set of symbols, F the collection of finite subsets of C. A function
L is a list assignment to a graph G if L assigns to each vertex of G a finite subset of C.
A proper L-coloring occurs when adjacent ...
Some Studies on Modeling and Simulation of a Disc Brake System for Squeal Prediction
(2006-08-15)
Most mechanical systems that involve a sliding contact experience some degree of friction induced self-excited vibration. A well known example is brake squeal which is a top concern for automotive companies, who must spend ...
Some Studies on the Dynamic Response of Aluminum Cylindrical Shells Using Acoustic Excitation
(2016-01-27)
An understanding of the vibration and acoustic properties of cylindrical shells is vital if we are to solve noise problems in a wide range of practical applications, especially those that occur in pipes, ducts, aircraft ...
Some Systems of Ordinary Differential Equations from Cancer Modeling: Qualitative Analysis and Optimal Treatment
(2011-07-25)
In this thesis, we study four systems of ordinary differential equations, which model the interrelationships between different cell populations while tumor cells exist, and treatments, such as immunotherapy, chemotherapy, ...
Some Techniques in the Control of Dynamic Systems with Periodically Varying Coefficients
(2007-12-15)
The goal of this dissertation is to develop control system design methods for dynamic systems with time periodic coefficients. These systems arise naturally in many branches of science and engineering. As a rule, time ...
Sorority/Fraternity Facilities: Does Type Make a Difference in the Member Experience?
(2020-04-20)
The physical environment on a college campus plays an important role in enhancing student learning and positive well-being (Garcia, 2017; Strange & Banning, 2015) and can influence a student’s sense of community and campus ...
Sorption and Biodegradation of Pharmaceutical Compounds in Biological Wastewater Treatment Process
(2007-12-15)
This study was performed to investigate the removal mechanisms of pharmaceutical compounds (PhACs) in biological treatment processes. The removal efficiencies and byproducts of three model compounds including 17a-ethinylestradiol ...
Sorption of Arsenic by Iron Sulfide Made by Sulfate-reducing Bacteria: Implications for Bioremediation
(2008-12-15)
In this study, data from field bioremediation experiments, geochemical modeling, and laboratory batch experiments were integrated with published data on arsenic (As) sorption and coprecipitation onto growing iron (Fe)-sulfide ...
Sorption of Thorium Onto Subsurface Geomedia
(2011-11-17)
Radionuclide contamination has been a significant environmental problem at US Department of Energy (USDOE) sites for many years. In addition, a final disposal solution for radioactive waste, such as deep geological ...
Sorption/Desorption and Photodegradation of Dispersed Oil Components in Marine Ecosystem
(2015-08-06)
This effects of a prototype oil dispersant on solubilization, sorption, and desorption of three model Polycyclic aromatic hydrocarbons (PAHs) in sediment-seawater systems were investigated. Increasing dispersant dosage ...
Sorptive Removal of Per- and Polyfluoroalkyl Substances (PFAS) from Water by Biochars
(2023-05-01)
This thesis aims to employ biochar (a carbonaceous material) as a cost-effective sorbent to remove per- and polyfluoroalkyl substance (PFAS) from water by two case studies. Study 1 seeks to identify which biochars perform ...
Sorry, Mario, but Our Better Representations of Women are in Another Video Game: A Qualitative Study on Women’s Perspective of Women Video Game Characters
(2021-04-19)
The representations of women characters in video games have always been scrutinized for their stereotyped and sexualized appearance by scholars and gamers. Yet these arguments have not focused enough on the players that ...
