Parallel Algorithms For Single-Layer Channel Routing, Ronald I. Greenberg, Shih-Chuan Hung, Jau-Der Shih

Computer Science: Faculty Publications and Other Works

We provide efficient parallel algorithms for the minimum separation, offset range, and optimal offset problems for single-layer channel routing. We consider all the variations of these problems that are known to have linear- time sequential solutions rather than limiting attention to the "river-routing" context, where single-sided connections are disallowed. For the minimum separation problem, we obtain O(lgN) time on a CREW PRAM or O(lgN / lglgN) time on a (common) CRCW PRAM, both with optimal work (processor- time product) of O(N), where N is the number of terminals. For the offset range problem, we obtain the same time and processor …

Reflections On The Gao Report On The Nuclear Triad, David W. Hafemeister

Physics

Senate Hearings on the GAO report on the nuclear triad and on the START treaty showed that vulnerabilities of the U.S. triad were vastly over‐stated, that the performance of new projected strategic systems was over‐estimated, and that the performance of existing U.S. strategic systems was under‐estimated. These exaggerations enhanced the psychological (Freud) aspects of the Cold War and compromised logic (Newton).

With the end of the Cold War it is imperative that we re‐examine the basic premises that guided the choices of the strategic nuclear systems. The initial bottom line is that these systems were successful in that they did …

Three-Dimensional Direct Simulation Monte Carlo Method For Slider Air Bearings, Alejandro Garcia, W. Huang, D. B. Bogy

Faculty Publications

The direct simulation Monte Carlo (DSMC) method is used to solve the three-dimensional nano-scale gas film lubrication problem between a gas bearing slider and a rotating disk, and this solution is compared to the numerical solution of the compressible Reynolds equations with the slip flow correction based on the linearized Boltzmann equation as presented by Fukui and Kaneko [molecular gas film lubrication (MGL) method] [ASME J. Tribol. 110, 253 (1988)]. In the DSMC method, hundreds of thousands of simulated particles are used and their three velocity components and three spatial coordinates are calculated and recorded by using a hard-sphere collision …

Factors Affecting Collision & Grounding Losses In The Uk Fishing Fleet, Malcolm Findlay

Other Faculty of Science and Engineering Theses

Examination of the literature reveals a paucity of dedicated research into collisions and groundings involving UK fishing vessels. The aim of this research was to provide answers to fundamental questions regarding the factors that contribute to fishing vessel traffic losses. Data for this study were gathered from a broad range of sources and an eclectic range of techniques employed in their analysis. The recent development of the UK fishing fleet and the pattern of losses from all causes is investigated for the period 1975 to 1994. Fishing vessel collision and grounding losses are then set in relative perspective by comparison …

Mathematical Modelling Of The Dynamic Response, In Six Degrees Of Freedom, Of Small Vessels In A Seaway, Barbara Diana Wallis

Other Faculty of Science and Engineering Theses

This thesis treats the motion of a small vessel described in six degrees of freedom. There are three are translation equations of motion and the other three are equations of angular motion. The aim is to develop a model with a sound mathematical base and use experimentation to find forces to aid the completion of the model, with the intention of use in an auto pilot, by the following means: 1) By solving the equations of motion for large movements, with given sea and wind conditions and also with given control forces and moments. 2) Deduce the forces and moments …

The Impact Of A Silvopastoral Agroforestry System, Maria Penn

Other Faculty of Science and Engineering Theses

There is increasing pressure in the UK to adopt alternative, sustainable uses for agricultural land. New schemes indicate a trend towards lowland afforestation schemes which are a very new concept in Britain. One such scheme is agroforestry whereby trees and a crop are grown together on the same unit of land. Very little is known about the impact of agroforestry on soil hydrology and soil water nitrate distribution of trees planted at a regular spacing into grazed grassland. In this case a lowland grazed silvopastoral agroforestry system in Devon, UK, was monitored to determine the impact upon the soil by …

Ecophysiology Of Neomysis Integer (Mysidacea: Peracarida), Stephen Derek Roast

School of Biological and Marine Sciences Theses

Neomysis integer (Leach) (Peracarida: Mysidacea) is a common component of the hyperbenthos of Western European estuaries, and this study focused on the ecophysiology and ecotoxicology of this mysid. Behavioural and physiological responses of N. integer to physical and chemical variables (current velocity, substratum type, temperature and salinity) were measured in the laboratory to gain better understanding of how this mysid maintains position in estuaries. Current velocity was the most important factor controlling position maintenance, and N. integer had a maximum swimming speed of c. 9cm sˉ¹. Position maintenance was facilitated by a muddy substratum and was not affected by salinity. …

Building And Implementing A Program Review For Gifted Education In An Urban School District, Anna Mae Bagby

Graduate Research Papers

In June of 1996, the Board of Education of the Waterloo School District, which is considered an urban school district, requested that all externally funded programs be reviewed. This included the Expanded Learning Program (ELP). The emphasis was to determine strengths and needs of ELP and the needs of gifted students in the regular classroom. A committee was formed, composed of ELP staff and parents of identified gifted students, who developed surveys which were sent to all ELP parents (K-12), all identified students, (K-12), and selected classroom teachers and specialists (K-8). Data were compiled and summarized according to (1) major …

The Use Of Multiple Intelligences In Designing Curriculum For An Early Childhood Classroom, Dawn Osterhaus

Graduate Research Papers

Early childhood curriculum implementation is not yet well represented in the literature pertaining to multiple intelligences. For purposes of this project, the literature pertaining to early childhood classrooms where the seven multiple intelligences were implemented was reviewed, and a preschool implementing the seven multiple intelligences has been written. This curriculum makes a difference in how the authors' lesson plans are designed and classroom activities are chosen. The resulting curriculum may also make a difference in how other early childhood educators set up their overall curriculum, and provides an easy-to-follow resource guide of potential use when planning individual units and activities.

Privacy Issues Dealing With Technology : A Review Of The Literature, Kimberly S. Mccoy

Graduate Research Papers

The sophisticated applications of technology are expanding everyday. Unfortunately, so are the many concerns individuals in society are having about their right to privacy. The actual regulations dealing with one's right to privacy has not expand as rapidly as the applications of technology. Individuals using various types of technology are under the assumption their activities are private; however, this is not the case. It does not seem to matter if you are using a computer for communications work, school, or in the "privacy" of your own home, there is absolutely no privacy when dealing with this type of technology.

The Integration Of Academic And Vocational Education, John Pisapia, Earl Riggins

MERC Publications

Vocational and academic education in U.S. high schools became separate entities around the turn of the century. Academic education has historically conisted of courses including English, history, mathematics, science, foreign languate, and fine arts. Such an education prepares studens for further education at the college or university level. Such an education may be supplemented with courses which familiarize students with the uses of technology. Occupational skills trining hs not been a component of academic education. Traditionally, vocational education has focued on specific skill training for entry-level jobs by offering students training in occupationally specific areas. While a large number of …

Summing Up: Questions And Answers On The Comprehensive Test Ban Treaty, David W. Hafemeister

Physics

My experiences with the ratification of the Strategic Arms Reduction Treaty, the Threshold Test Ban Treaty, and the Conventional Armed Forces in Europe Treaty have led me to conclude that presenting technical issues early in the process greatly reduces their politicization during the ratification end game. This chapter summarizes the important issues that will be raised during the debate on ratification of the Comprehensive Test Ban Treaty. It uses a compact question and answer format to cover the following topics: I. Nuclear Proliferation, II. Nuclear Arms Control, III. Warhead Reliability and Yield for National Security, IV. Warhead Safety, V. Verification, …
