Further Studies On Fire Retardant Polystyrene By Friedel–Crafts Chemistry, Zhitao Wang, David D. Jiang, Charles Wilkie, Jeffery W. Gilman

Chemistry Faculty Research and Publications

The combination of a copolymer of 4-vinylbenzyl alcohol and styrene with 2-ethylhexyldiphenylphosphate (DPP) and with metal chlorides has been studied by TGA, radiative gasification, Cone Calorimetry, and oxygen index measurements. Evidence is presented in support of a cross-linking reaction with the additives and the copolymer, which proceeds through a Friedel–Crafts mechanism. This approach reduces the peak heat release rate (HRR) by 60% as measured in the Cone Calorimeter. There is a significant reduction in the mass loss rate during the thermal degradation, and evidence of char formation is observed in the radiative gasification experiments.

The Assault On The Global Economy, Murray L. Weidenbaum

Murray Weidenbaum Publications

The global economy is under assault by a strange alliance of radical groups and several mainstream environmental organizations. The outfits from the far left are long-term opponents of the capitalist system, both at home and abroad, so their opposition to trade between nations is neither new nor newsworthy. It is surprising, however, that organizations like the Sierra Club and Friends of the Earth have joined this effort to oppose the modern economy. This paper attempts to respond to these views. Isolationist policies are a foolhardy, futile pursuit in today's interconnected, globalized economy.

Power, Performance, And Perception (P3): Integrating Usability Metrics And Technology Acceptance Determinants To Validate A New Model For Predicting System Usage, Alan P. Fiorello

Theses and Dissertations

Currently, there are two distinct approaches to assist information technology managers in the successful implementation of office automation software. The first approach resides within the field of usability engineering, while the second approach is derived from the discipline of management information systems (MIS). However, neither approach has successfully produced conclusive evidence that explains what characteristics facilitate system use as well as influence user acceptance of the system. This study reports on the validity of a new model, entitled the Power, Performance, Perception (P3) model, that links the constructs of usability engineering to user acceptance. Additionally, speech recognition software (SRS) was …

Bargaining In The Shadow Of Democracy, David Dana, Susan P. Koniak

Faculty Scholarship

The tobacco industry's gambit did not fail because Congress refused to trade its law-making authority for money. Rather, it failed, at least for the time being, because the parties could not agree on terms. Perhaps another industry (with a better public image than tobacco) will have better luck. Congress may have proved itself a difficult bargaining partner, but it has also demonstrated its willingness to negotiate. Before Congress goes any further down this path or other government entities decide they can bargain their law-making authority for money or other goods, we, as a nation, should consider the wisdom of such …

Multimode Solution For The Reflection Properties Of An Open-Ended Rectangular Waveguide Radiating Into A Dielectric Half-Space: The Forward And Inverse Problems, R. Zoughi, Aaron D. Benally, Karl Joseph Bois

Electrical and Computer Engineering Faculty Research & Creative Works

Open-ended rectangular waveguides are extensively used in nondestructive dielectric material evaluation. The dielectric properties of an infinite-half space of a material are calculated from the measured reflection properties referenced to the waveguide aperture. This calculation relies on a theoretical and numerical derivation of the reflection coefficient likewise referenced to the waveguide aperture. Most of these derivations assume the dominant mode field distribution across the waveguide aperture. However, when dealing with low permittivity and low loss dielectric materials, there may exist significant errors when calculating the dielectric properties from the measured reflection coefficient. These errors have also shown to be more …

Economic Dispatch And Optimal Sizing Of Battery Energy Storage Systems In Utility Load-Leveling Operations, Chin H. Lo, Max Darwin Anderson

Electrical and Computer Engineering Faculty Research & Creative Works

Battery energy storage (BES) systems show promise of savings for both the utility and the customer. An algorithm combining multi-pass dynamic programming (MPDP) with a time-shift technique has been developed for two purposes: economic dispatch of BES and finding optimal BES power and energy capacities in a power system. Due to the daily cyclic nature of the load curve, a 168-hour load curve is decomposed into seven 24-hour subsections for easy management. Each subsection is treated independently. Decomposition can save computation time and computer memory. A time-shift technique provides better starting state values and improves the finding process of the …

An Accurate Method Of Neglecting Dynamic Saliency Of Synchronous Machines In Power Electronic Based Systems, Steven Pekarek, E. A. Walters

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, motivations for neglecting dynamic saliency in the detailed models of power electronic based systems are presented, A new method of neglecting dynamic saliency is then introduced in which approximate operational impedances are derived from original dynamic salient models. New machine parameters are obtained by fitting to the approximate impedance curves, yielding model parameters in which dynamic saliency is eliminated. An example synchronous machine/converter system is provided that demonstrates the accuracy and increased simulation efficiency resulting from this technique. Therein, errors resulting from neglecting dynamic saliency are reduced from greater than 25% using traditional approximations to less than …

Analysis And Average-Value Modeling Of An Inductorless Synchronous Machine Load Commutated Converter System, J. T. Alt, Scott D. Sudhoff, B. E. Ladd

Electrical and Computer Engineering Faculty Research & Creative Works

Synchronous machine fed load-commutated converters (SMLCCs) are commonly used for dc power sources in marine and aircraft power systems. The focus of this paper is to set forth a model for SMLCCs for use in transient stability studies involving these systems. Although there has been considerable work in this area, much of this work has assumed the existence of a dc link inductor whereupon the dc link current is approximately constant. In practice, this filter is often eliminated, whereupon previous models are no longer valid. A new average-value model is set forth for SMLCCs in which there is no dc …

An Efficient And Accurate Method Of Representing Magnetic Saturation In Physical-Variable Models Of Synchronous Machines, Steven Pekarek, E. A. Walters, B. T. Kuhn

Electrical and Computer Engineering Faculty Research & Creative Works

When analyzing machine/converter systems it is convenient to represent the stator variables in physical (abc) form. It has recently been shown that a physical-variable voltage-behind-reactance form of the synchronous machine model can be derived which is numerically more efficient than existing physical-variable models. In this research, a new voltage-behind-reactance model is derived which incorporates the effects of magnetic saturation. This model is shown to have the same numerical efficiency of the unsaturated model and is readily implemented in either circuit-based or differential-equation based simulation languages. An example system is provided which demonstrates the accuracy and efficiency of this model for …

Extension Organization Of The Future: Linking Emotional Intelligence And Core Competencies, Deliece Ayers, Barbara Stone

Journal of Extension

Recruiting, hiring, and keeping desirable employees have been fundamental goals in institutions since before the Industrial Revolution. Traditionally, developing an exceptional workforce has been a hit-or-miss process. Recently, however, national and international organizations like Amoco, Dupont, Federal Express, and the Texas Agricultural Extension Service building a workforce for the 21st century. have developed competency models to lure and keep good workers. Part of competency models is the idea that high emotional intelligence is valuable. Emotional Intelligence and competencies are a natural fit, and they will, no doubt, become increasingly popular as organizations recognize their importance in building a workforce for …

Community Mapping Exercises Provide Enhanced Participant Interaction In Visioning Processes, Connie Bodeen, Mark Hilliker

Journal of Extension

The public sector has utilized a variety of techniques to plan for the future since the 1950s. As these techniques have evolved, so has the level of public participation. Community Visioning processes used today rely heavily on public input. Community Mapping exercises provide enhancements to the visioning process by providing a more interactive and tactile method for creating a future vision for a community. By working in small groups and creating "Big and Bold Ideas" on a large-format map, participants create a graphic image of the future of their community that provides a platform for implementation.

Extension's Portfolio For The 21st Century: A Place For One-On-One Consultations, Peggy Petrzelka, Steve Padgitt, Wendy Wintersteen

Journal of Extension

Revisits the individual consultations that provided the base from which the Cooperative Extension Service grew. Using data gathered from clients' and Extension staff evaluations of one-on-one activities, our findings show these consultations have an economic and educational value for clients. The consultations benefit field specialists as well, augmenting their need assessments by providing information from in the field, providing opportunities for on-going research, and building credibility. It is maintained that continuing (or re-implementing) these consultations as part of Extension's portfolio for the 21st Century has mutual benefit, both to the client and to Extension.

Journal of Extension

Michigan State University Extension food, nutrition and health campus-based staff members conducted a needs assessment of county home economics agents to obtain information to drive decision making for programs, resources and training and to build rapport with county agents. The methods used to collect this crucial information were personal telephone interviews with 62 county agents and a follow-up printed questionnaire. Findings supplied a wealth of information for campus staff members to use to establish priorities about program planning and support, select or develop materials or other resources, and plan and implement training appropriate and helpful to county staff.

Helping Children Cope With Divorce, Beth D. Gaydos, Shelly Schwieterman, Bruce P. Zimmer

Journal of Extension

Children of divorce are at risk for increased emotional and educational problems including anxiety and depression. A two-hour, court mandated program entitled "Helping Children Cope with Divorce" was developed to help parents understand these risks as well as how to communicate with children about the divorce and help children adjust to the changes in the family. Through a variety of educational methods, parents learn how to keep children out of the crossfire. The authors have surveyed nearly 340 program participants with end-of-meeting evaluations which revealed that parents now recognize that their children are more affected by divorce than they realized.

Typically, the agriculture teacher would conduct demonstration work during the summer. Faculty members at the schools also worked with youth activities and home economics programs. The funding sources helped set precedents with a combination of state funding through the Land-grant university …

Taking R&E To The Next Level, Thomas W. Blaine, Stephen Hudkins, Charles R. Taylor

Journal of Extension

During the late 1980s, the business retention and expansion (R&E) program emerged as one of the most successful programs in Ohio State University Extension's Community Development area. As the economic recovery of the early 1990s turned into an economic expansion, business and civic leaders began to shift focus from general R&E efforts to issues related to labor force preparedness. A survey of businesses in Portage County undertaken four years after completion of an R&E program reveals that, while employers believe that local resources are available to help improve basic math and communication skills of employees, those skill levels are still …

Development Of Cfd Algorithms For Transient And Steady Aerodynamics, Fergal Boyle [Thesis]

Other Resources

Research carried out in the United States and in Europe over the last 20 years has led to the development of the advanced propeller, a small-diameter, highly-loaded, multi-bladed, swept, variable-pitch propeller, that can achieve potential fuel savings of 30% over an equivalent technology turbofan engine at competitive speed and altitudes.

In this work an implicit finite-volume algorithm is developed for predicting the transient flow around an advanced propeller under asymmetric inflow conditions. The development of the unsteady propeller algorithm evolves from a family of methods for progressively more complex applications. In total six algorithms are developed: three steady and three …
