Eigenvalue Placement and Stabilization by Constrained Optimization

A pole placement algorithm is proposed which uses constrained nonlinear optimization techniques on a finite dimensional model of a linear n degree of freedom system. Low order feedback control is assumed where r poles may be assigned; r being the rank of the sensor coefficient matrix. It is shown that by combining feedback control theory methods with optimization techniques, one can ensure the stability characteristics of a system, and can alter its transient response

Gulf War Illness And Injuries

AN ABSTRACT OF THE RESEARCH PAPER OF DIANNA S. INMAN, for the Master of Science degree in REHABILITATION COUNSELOR, presented on May 2011, at Southern Illinois University Carbondale. TITLE: GULF WAR ILLNESS AND INJURIES MAJOR PROFESSOR: D. Shane Koch, Ph D., CRC The Persian Gulf War, Afghanistan, and Iraq Enduring Freedom are wars our United States troops have been involved in the Middle East. The goal of this research paper is to present and discuss the injuries and illness some of our soldiers are experiencing in their tour of duty in the Middle East. I will focus on three conditions some of our veterans are suffering from, Gulf War Illness(GWI), Post Traumatic Stress Disorder (PTSD) and Traumatic Brain Injury (TBI). Diagnosis and treatment of PTSD, TBI, and GWI will be discussed

The Green Deal: A Call for Changed Lifestyle

Each year the Margaret Chase Smith Library sponsors an essay contest for high school seniors. This year students were asked for a comprehensive national energy policy, addressing the topic from multiple perspectives and surveying the economic, environmental, political social and historical considerations that must go into any viable long-term solutions. Featured here is Samuel S. Inman’s thoughtful and well-articulated 2007 first place prize-winning essay

Microscopy of glazed layers formed during high temperature sliding wear at 750C

The evolution of microstructures in the glazed layer formed during high temperature sliding wear of Nimonic 80A against Stellite 6 at 750 ◦C using a speed of 0.314ms−1 under a load of 7N has been investigated using scanning electron microscopy (SEM), energy dispersive analysis by X-ray (EDX), X-ray diffraction (XRD) analysis, scanning tunnelling microscopy (STM) and transmission electron microscopy (TEM). The results indicate the formation of a wear resistant nano-structured glazed layer. The mechanisms responsible for the formation of the nano-polycrystalline glazed layer are discussed

Evolving Legal Protections for Indigenous Peoples in Africa : Some Post-UNDRIP Reflections

Prior to the adoption of the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) many African states held a unified and seemingly hostile position towards the UNDRIP exemplified by the concerns outlined in the African Group's Draft Aide Memoire. In order to gain a better understanding of the protections offered to indigenous peoples on the African continent, it is necessary to examine the concerns raised in the aforementioned Draft Aide Memoire and highlight how these concerns have been addressed at the regional level, effectively changing how the human rights norms contained within the UNDRIP are seen, understood and interpreted in the African context. The purpose of this article is to do just that: to examine in particular how the issue of defining indigenous peoples has been tackled on the African continent, how the right to self-determination has unfolded for indigenous peoples in Africa and how indigenous peoples' right to free, prior and informed consent has been interpreted at the regional level.Peer reviewe

Building a future...An exploration of the contribution of educational provision to clients’ well-being at Southwark Day Centre for Asylum Seekers

This research project builds on previous work, ‘Beneath the Surface’ (Cogo, Inman, McCormack, Rogers 2018) which focussed on how clients at Southwark Day Centre for Asylum Seekers (SDCAS) understood and evaluated their well-being. One of the areas touched on in that research was the role of educational activities in developing the well-being of clients. This report describes in depth the ways in which the educational provision offered in the centre contributes to the well-being of clients and how this contribution might be enhanced. The report focuses on two areas of education provision; gardening and storytelling and explains how they contribute to the well-being of the clients. The interview data confirms that the activities in these two areas help to build clients’ psychological, physical and social resources and have a positive effect on how clients feel and how they function in the world. The report ends with recommendations as to how SDCAS might ensure that gardening and storytelling continue to benefit the well-being of clients and also as to what might be put in place to strengthen the activities

Stories from lockdown: the impact of the Covid19 pandemic on the well-being of clients at Southwark Day Centre for Asylum Seekers (SDCAS)

The report describes the findings of research on how the Covid 19 related lockdowns affected the well-being of clients at the Southwark Day Centre for Asylum Seekers. A small number of clients were interviewed about the practical issues of housing, food, money and about their physical and mental health during the periods of lockdowns. They were also asked about support from the Southwark Day Centre for Asylum Seekers. The report describes the experiences of these clients between March 2020 and March 202

Micromechanics of fatigue in woven and stitched composites

The goal is to determine how microstructural factors, especially the architecture of microstructural factors, control fatigue damage in 3D reinforced polymer composites. Test materials were fabricated from various preforms, including stitched quasi-isotropic laminates, and through-the-thickness angle interlock, layer-to-layer angle interlock, and through-the-thickness stitching effect weaves. Preforms were impregnated with a tough resin by a special vacuum infiltration method. Most tests are being performed in uniaxial compression/compression loading. In all cases to date, failure has occurred not by delamination, but by shear failure, which occurs suddenly rather than by gradual macroscopic crack growth. Some theoretical aspects of bridging are also examined
