A Cross-Layer Approach To Increase Spatial Reuse And Throughput For Ad Hoc Networks, Steven Boyd

All Theses

Ad hoc networks employing adaptive-transmission protocols can alter transmission parameters to suit the channel environment. Channel-access mechanisms are used to govern temporal use of the transmission medium amongst nodes. Effective operation of a channel-access mechanism can improve the ability of an adaptive-transmission protocol to accommodate changing channel conditions. The interoperability of these two mechanisms motivates cross-layer design of adaptive-transmission protocols.
In this thesis we examine the integration of a new channel-access mechanism with a physical-layer adaptive-transmission protocol to create a cross-layer protocol with enhanced capabilities. We derive specific physical-layer measurements which are used to control channel-access behavior in a distributed …

The Architecture Of Enabling Technology In The Critical Care Setting: The Role Of Architecture In Addressing The Health Care - Technology Paradox, Matthew Nitch

All Theses

Health care architecture, particularly tertiary care settings, which have the sickest people, and most advanced medical care, should accommodate and employ technology in ways that are both therapeutic and enabling. Although technology in the tertiary care setting is generally considered beneficial, it can sometimes have negative impacts, cause stress and result in poor health outcomes. Norman Cousins said in his book Anatomy of an Illness, 'Many doctors are increasingly aware of the circular paradox [of the intensive care unit]. It provides better electronic aids than ever before for dealing with emergencies that are often intensified because they communicate a sense …

The Theoretical Basis For Addressing Poverty Through Mixed-Income Development, Mark L. Joseph, Henry S. Webber

Faculty Scholarship

This article examines the theoretical foundations upon which the rationale for mixed-income development as a strategy to confront urban poverty is built. The authors focus on four propositions that draw from theories on social networks, social control, culture and behavior, and the political economy of place. They assess available evidence about the relative importance of the four theoretical propositions. They conclude that the most compelling propositions are those that suggest that some low-income residents may benefit from a higher quality of life through greater informal social control and access to higher quality services. They find less evidence that socioeconomic outcomes …

2d Arbitrary Lagrangian-Eulerian (Ale) Model Of Blood Flow In The Left Ventricle Of The Heart / Zati Hakim Azizul Hasan, Azizul Hasan Zati Hakim

Student Works (2000-2009)

This research is a study of the dynamics of the heart valves and the blood using numerical computational technique. This numerical technique is known as the Arbitrary Lagrangian-Eulerian (ALE) and is introduced in a finite element environment. By means of a mesh movement method, the ALE uses separate sets of reference systems to study the fluid-structure interaction of the heart. The fluid domain is most conveniently described with respect to an Eulerian reference frame while a Lagrangian formulation is more appropriate for the structure domain. Due to the incompatibility factor of the two reference frames, coupling of the reference systems …

Using Duplication With Compare For On-Line Error Detection In Fpga-Based Designs, Daniel L. Mcmurtrey

Theses and Dissertations

Space destined FPGA-based systems must employ redundancy techniques to account for the effects of upsets caused by radiated environments. Error detection techniques can be used to alert external systems to the presence of these upsets. Readback with compare is an error detection technique commonly employed in FPGA-based designs. This work introduces duplication with compare (DWC) as an automated on-line error detection technique that can be used as an alternative to readback with compare. This work also introduces a set of metrics that is used to quantify the effectiveness and coverage of this error detection technique. A tool is presented that …

Asymmetric Games For Convolution Systems With Applications To Feedback Control Of Constrained Parabolic Equations, Boris S. Mordukhovich

Mathematics Research Reports

The paper is devoted to the study of some classes of feedback control problems for linear parabolic equations subject to hard/pointwise constraints on both Dirichlet boundary controls and state dynamic/output functions in the presence of uncertain perturbations within given regions. The underlying problem under consideration, originally motivated by automatic control of the groundwater regime in irrigation networks, is formalized as a minimax problemof optimal control, where the control strategy is sought as a feedback law. Problems of this type are among the most important in control theory and applications - while most challenging and difficult. Based on the Maximum Principle …

Large 3-D Deflection And Force Analysis Of Lateral Torsional Buckled Beams, Robert Parley Chase

Theses and Dissertations

This thesis presents research on the force and deflection behavior of beams with rectangular cross-sections undergoing lateral torsional buckling. The large 3-D deflection path of buckling beam tips was closely approximated by circular arcs in two planes. A new chain algorithm element was created from pseudo-rigid-body segments and used in a chain calculation that accurately predicted the force deflection relationship of beams with large 3-D deflections.

Shear-Wave Velocity Model Of Near-Surface Sediments, Site Response, And Building Damage: 1886 Charleston, South Carolina Earthquake, Cedric Fairbanks

All Dissertations

An updated small-strain shear wave velocity (Vs) model of near-surface sediments is constructed using measurements from over 90 investigation sites in the greater Charleston area. It is constructed by separating the Vs measurements into six major geologic units. The six units are: 1) man-made fills, 2) Holocene and late Pleistocene deposits, 3) the Wando Formation, 4) the Ten Mile Hill beds, 5) the Penholoway Formation and the Daniel Island beds, and 6) Tertiary deposits. Median Vs values for these units in the top 25 m are 145 m/s, 111 m/s, 189 m/s, 176 m/s, 285 m/s and 399 m/s, respectively. …

Collisions Of Red-Tailed Hawks (Buteo Jamaicensis), Turkey Vultures (Cathartes Aura), And Black Vultures (Coragyps Atratus) With Aircraft: Implications For Bird Strike Reduction, Bradley F. Blackwell, Sandra E. Wright

United States Department of Agriculture Wildlife Services: Staff Publications

From 1990 through 2003, 52,493 wildlife collisions with aircraft were reported to the U.S. Federal Aviation Administration (FAA); 97% of these incidents involved birds. The approximate cost to the civil aviation industry in the U.S.A. due to collisions of birds with aircraft (hereafter referred to as bird strikes) was $163.51 million in direct monetary losses and associated costs for the 14 year period (Cleary et al. 2004). Strikes with raptors (Falconidae and Accipitridae; including vultures, Cathartidae)accounted for approximately 28% of reported aircraft down time resulting from known-species bird strikes (known species =182942 hr; total for all birds = 244510 hr) …

Tass Mark Iv Photometric Survey Of The Northern Sky, Thomas Droege, Michael Richmond, Michael Sallman, Robert P. Creager

Articles

The Amateur Sky Survey (TASS) is a loose confederation of amateur and professional astronomers. We describe the design and construction of our Mark IV systems, a set of wide-field telescopes with CCD cameras which take simultaneous images in the V and IC passbands. We explain our observational procedures and the pipeline which processes and reduces the images into lists of stellar positions and magnitudes. We have compiled a large database of measurements for stars in the northern celestial hemisphere with V -band magnitudes in the range 7 < V < 13. This paper describes data taken over the four-year period starting November, 2001. One of our results is a catalog of repeated measurements on the Johnson-Cousins system for over 4.3 million stars.

A Comparison Of Heuristic And Human Performance On Open Versions Of The Traveling Salesperson Problem, James N. Macgregor, Edward P. Chronicle, Thomas C. Ormerod

The Journal of Problem Solving

We compared the performance of three heuristics with that of subjects on variants of a well-known combinatorial optimization task, the Traveling Salesperson Problem (TSP). The present task consisted of finding the shortest path through an array of points from one side of the array to the other. Like the standard TSP, the task is computationally intractable and, as with the standard TSP, people appear to be able to find good solutions with relative ease. The three heuristics used mechanisms that have been cited as potentially relevant in human performance in the standard task. These were: convex hull, nearest neighbor, and …

Visual Learning Objects: Enable Faculty To Focus On Active Learning, Pandeli Glavanis Dr.

Faculty Journal Articles

In two recent issues of New Chalk Talk (Vol.6, Issue 2 & 6) I suggested that “learning objects” enhance active learning and that “visual learning objects”, in particular, contribute significantly to the learning relationship. In this issue I wish to elaborate on how such “visual learning objects” are the key element that liberates faculty from having to design and construct their own demonstrations and illustrations (reinvent the wheel) in their respective courses and thus enable them to focus on critical and active learning instead.
