Invariant Measures For Set-Valued Dynamical Systems, Walter Miller, Ethan Akin Jan 1999

Invariant Measures For Set-Valued Dynamical Systems, Walter Miller, Ethan Akin

Mathematics and Statistics Faculty Research & Creative Works

A continuous map on a compact metric space, regarded as a dynamical system by iteration, admits invariant measures. For a closed relation on such a space, or, equivalently, an upper semicontinuous set-valued map, there are several concepts which extend this idea of invariance for a measure. We prove that four such are equivalent. In particular, such relation invariant measures arise as projections from shift invariant measures on the space of sample paths. There is a similarly close relationship between the ideas of chain recurrence for the set-valued system and for the shift on the sample path space. ©1999 American Mathematical …

Osmia Spp. Reared In Artificial Nesting Sites In A Backyard Environment, R. L. Wilson, C. A. Abel, S. G. Mcclurg

Journal of the Iowa Academy of Science: JIAS

Controlled pollination in field cages is used at the United States Department of Agriculture - Agricultural Research Service North Central Regional Plane Introduction Station (NCRPIS) for seed increase of several plane species. Honey bees, Apis mellifera L., have been used almost exclusively for several years. Recently we began investigating other pollinating insects for controlled pollination. 0smia cornifrons (Radoszkowski), a solitary bee imported from Japan, has been an excellent early-season pollinator. We placed domiciles of these bees in backyards of the NCRPIS staff to aid us in providing adequate numbers of bees for use in field cages the following growing season. …

A Municipal Inventory And Evaluation Of Natural Areas: History And Methodology, William R. Norris, Donald R. Farrar Jan 1999

A Municipal Inventory And Evaluation Of Natural Areas: History And Methodology, William R. Norris, Donald R. Farrar

Journal of the Iowa Academy of Science: JIAS

An inventory of natural areas in the vicinity of Ames, Iowa was conducted (1990-1994) in response to conflicts arising when significant natural areas were encountered on lands approved for development by the City of Ames (Iowa) Planning Office. Methods for objective evaluation of woodland and prairie quality were developed for use during the inventory. The woodland method is based on four components: I) Diversity of expected species, H) Structure of canopy and understory layers, III) Fidelity of species to the habitat and IV) absence of Introduced Species. Rules are explicitly stated for the scoring of each component for both the …

Review Of The Applications Of Neural Networks In Chemical Process Control - Simulation And Online Implementation, Mohd Azlan Hussain Jan 1999

Review Of The Applications Of Neural Networks In Chemical Process Control - Simulation And Online Implementation, Mohd Azlan Hussain

Pre-2000

As a result of good modeling capabilities, neural networks have been used extensively for a number of chemical engineering applications such as sensor data analysis, fault detection and nonlinear process identification. However, only in recent years, with the upsurge in the research on nonlinear control, has its use in process control been widespread. This paper intend to provide an extensive review of the various applications utilizing neural networks for chemical process control, both in simulation and online implementation. We have categorized the review under three major control schemes; predictive control, inverse-model-based control, and adaptive control methods, respectively. In each of …


Including Best Available Science In The Designation And Protection Of Critical Areas Under The Growth Management Act, Alan D. Copsey Jan 1999

Including Best Available Science In The Designation And Protection Of Critical Areas Under The Growth Management Act, Alan D. Copsey

Seattle University Law Review

This Article discusses the meaning of these latter two requirements: the requirements to include best available science and to give special consideration to the conservation of anadromous fisheries. Section II defines "best available science" by examining the fundamental characteristics of scientific information applied in the context of the GMA. Expanding on the work of a technical team convened by DCTED, this Article suggests an approach useful for identifying scientific information and assessing which of that information should be considered the "best available science." Section III concludes that the requirement of RCW 36.70A. 172(1) to include best available science is a …


An Efficient Implementation Of The Transportation Problem, Alissa Michele Sustarsic Jan 1999

An Efficient Implementation Of The Transportation Problem, Alissa Michele Sustarsic

UNF Graduate Theses and Dissertations

The transportation problem is a special type of linear program in which the objective is to minimize the total cost of shipping a single commodity from a number of sources (m) to a number of destinations or sinks (n).

Because of the special structure of the transportation problem, a special algorithm can be designed to find an optimal solution efficiently. Due to the large amount of information in the problem, judicious storage and management of the data are essential requirements of any viable implementation of the transportation algorithm.

Using sparse matrix techniques to store the solution …


Ethics And The Internet Studies, Steve Jones Jan 1999

Ethics And The Internet Studies, Steve Jones

Iowa Journal of Communication

Insufficient attention has been paid to the practical as well as methodological dimensions of the ethics of online research. Though discussion of research methods for the study of online social phenomena has recently come to the fore, questions concerning the development and implementation of ethical guidelines, the conditions of research, and basic definitions of objects and subjects of study have yet to be fully engaged. This essay maps out some of the terrain of that engagement. It asks questions about the consequences of research, and notes that the Internet is not only technology but a practice that must be situated …


Minority Preferences Reconsidered, Terrance Sandalow Jan 1999

Minority Preferences Reconsidered, Terrance Sandalow

Reviews

During the academic year 1965-66, at the height of the civil rights movement, the University of Michigan Law School faculty looked around and saw not a single African-American student. The absence of any black students was not, it should hardly need saying, attributable to a policy of purposeful exclusion. A black student graduated from the Law School as early as 1870, and in the intervening years a continuous flow of African-American students, though not a large number, had been admitted and graduated. Some went on to distinguished careers in the law.


History Of The Forum On Physics And Society, David W. Hafemeister Jan 1999

History Of The Forum On Physics And Society, David W. Hafemeister

Physics

Physics is a major component of many of society's difficult issues: nuclear arms and their proliferation, energy shortages and energy impacts, climate change and technical innovation. Because physics principles underlie so many of these societal issues and because physics offers a way to quantify some aspects of them, members of the American Physical Society (APS) should be encouraged to understand, analyze and debate them. That's precisely why APS members formed the Forum on Physics and Society (FPS). To those of us who have been long involved in FPS affairs, it seems but yesterday that we attended the organizing meeting at …

Research outputs pre 2011

The project reported on here set out, on a basis of cooperation between Aboriginal and non-Aboriginal investigators working in university, educational system and classroom contexts, to lead to understandings which would enable a more accessible ("userfriendly") education to be provided for students in primary and secondary schools who are speakers of Aboriginal English.

Specifically, in the context of schools of the Education Department of Western Australia, the project sought to:

1. extend knowledge and understanding of Aboriginal English and its areas of contrast with standard Australian English;

2. provide clarification in the following under-researched areas of Aboriginal English:

a) semantic …


On The Numerical Solution Of The Cylindrical Poisson Equation For Isolated Self -Gravitating Systems., Howard Saul Cohl Jan 1999

On The Numerical Solution Of The Cylindrical Poisson Equation For Isolated Self -Gravitating Systems., Howard Saul Cohl

LSU Historical Dissertations and Theses

This dissertation addresses the need for an accurate and efficient technique which solves the Poisson equation for arbitrarily complex, isolated, self-gravitating fluid systems. Generally speaking, a potential solver is composed of two distinct pieces: a boundary solver and an interior solver. The boundary solver computes the potential, phi(xB) on a surface which bounds some finite volume of space, V, and contains an isolated mass-density distribution, rho(x). Given rho(x) and phi(xB), the interior solver computes the potential phi(x) everywhere within V. Herein, we describe the development of a numerical technique which efficiently solves Poisson's equation in cylindrical coordinates on massively parallel …

Clarinet Concertos By Post World War Ii Generation Norwegian Composers: Bjorn Kruse, Olav Berg, And Rolf Wallin., Beverly Ann Gibson

LSU Historical Dissertations and Theses

A substantial body of Norwegian clarinet literature exists that is infrequently performed outside of the Scandinavian countries and Europe. A new generation of composers emerged in the 1980s who have made visible their own individual approaches to composition. This monograph focuses on a selection of clarinet concertos composed by Bjorn Kruse (b. 1946), Olav Berg (b. 1949), and Rolf Wallin (b. 1957) which represent the most extensive pieces for clarinet in the respective composers' outputs to date and have been awarded prizes in composition contests. The composers have distinguished themselves as leading figures in the contemporary music scene in Norway, …


Pine-Polyethylene (Wood -Polymer) Composites: Synthesis And Mechanical Behavior Characterization., Parviz S. Razi Jan 1999

Pine-Polyethylene (Wood -Polymer) Composites: Synthesis And Mechanical Behavior Characterization., Parviz S. Razi

LSU Historical Dissertations and Theses

Processing of recycled wood chips, recently produced after extraction of creosote from telephone posts and railroad crossties, and combining them with a recycled polymer for the synthesis of novel composite materials would initiate a new trend toward preservation of natural resources. The challenge is taken in this work to produce and study the properties of such materials for further advancement of science. In the present study, addition of pine wood chips to HDPE reduced the tensile strength and break strain in tensile loading. Smaller wood chips generally resulted in smaller reductions. Peak load, modulus of rupture and stiffness were slightly …


Design Of Work-Rest Schedules For Vdt Operators., Rana Balci Jan 1999

Design Of Work-Rest Schedules For Vdt Operators., Rana Balci

LSU Historical Dissertations and Theses

The number of musculoskeletal and psychological discomforts is increasing as a result of continuing growth of VDT work. Although ergonomic improvements in workstation design can be applied, an effective work-rest schedule is an economical way to reduce these problems. The objective of this research was to determine an effective work-rest schedule for VDT operators. In addition to a discomfort questionnaire, performance and electromyography measurements from trapezius and flexor carpi radialis were used. Three different work-rest schedules were applied: 60-minute work/10-minute rest, 30-minute work/5-minute rest, and for the third schedule, the subjects received four breaks from VDT work each hour additional …
