Analysis of Algorithms for Velocity Estimation from Discrete Position Versus Time Data

Algorithms for constructing velocity approximations from discrete position versus time data are investigated. The study is limited to algorithms suitable to provide velocity information in discrete-time feedback control systems such as microprocessor-based systems with a discrete position encoder. Velocity estimators based on lines per period, reciprocal-time, Taylor series expansion, backward difference expansions, and least-square curve fits are presented. Based on computer simulations, comparisons of relative accuracies of the different algorithms are made. The least-squares velocity estimators filtered the effect of imperfect measurements best, whereas the Taylor series expansions and backward difference equation estimators respond better to velocity transients

Kentucky Crossroads: Essays Look At Politics And Combat In Bluegrass Country

More than 70 years have passed since a book has appeared that addresses Kentucky\u27s role in the Civil War and its own internal conflict in the detail that the complexity of the twin issues requires. It cannot be for a lack of drama; nearly everyone who writes on the topic quotes Lincoln about the imp...

What We Know About the Irish in the United States: Reflections on the Historical Literature of the Last Twenty Years

For many years, scholars and others who wrote about the Irish in theUnited States focused on the Catholic Irish, especially those who arrived around the time of the Irish Potato Famine and the several decades after that great calamity. Over roughly the last twenty years, the historical literature has come to grips with the more varied nature of the Irish experience in the United States and now better reflects the diversity of the varied religious backgrounds of the Irish in the United States. Further, while the literature on the Catholic Irish in the United Statesfocused heavily on the Irish in northeastern cities there has been increasing attention to the Irish in other sections of the United States. The result of this new research and writing has been to expand and enrich our understanding of the Irish experience in the United States. My intention in this article is to sketch out this expanded and enriched understanding of the Irish experience in the United States which is also part of a larger, global process, the Irish Diaspora. The Diaspora approach to the study of the Irish in the United States offers a greatmany advantages. One of the limitations on the study of United States history has long “American exceptionalism.” In its simplest form this approach begins by seeing United States history as a unique experience, separate from the larger flow of world events, and stresses the distinctiveness of the American (U.S.) experience. The Diaspora approach moves away from this and places the experience of theIrish in the United States in global context.

Review of \u3ci\u3eBeyond the American Pale: The Irish in the West, 1845-1910\u3c/i\u3e by David M. Emmons

David Emmons\u27s book on the Butte Irish (1989) helped begin a scholarly reassessment and investigation of the Irish experience in America, expanding it well beyond East Coast Irish communities and a few others in the Midwest. It had a significant impact on other scholars, myself included. His new book, which deals with the Irish experience in the West, therefore, has been much anticipated. Beyond the American Pale will not disappoint those who have waited for Emmons\u27s take on the larger picture of the Irish in the West, although it may not be what many expect

Application and Effectiveness of Telehealth to Support Severe Mental Illness Management: Systematic Review

Background: It is important that people with SMI receive early interventions to prevent mental health deterioration or relapse. Telecommunications and other technologies are increasingly used to assist healthcare delivery (‘telehealth’) , providing service users with immediate real-time information to improve the management of chronic health conditions. Telehealth has been found to be successful in improving management and symptoms across a number of health conditions, whilst also being acceptable to users. Initial findings suggest technology could improve quality of life in people with SMI. Objectives: This systematic review aimed to identify the variety of uses and efficacy of teleheal th technology for SMI. Methods: We systematically searched electronic databases from inception to March 2016 (MEDLINE, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials, AMED, He alth Techno logy Assessment, CINAHL plus and NHS EED ) for randomised controlled trials (RCTs) evaluating telehealth for adults with SMI , published in English. Additional literature was identified by searching reference lists of key articles. The articles meeting the inclusion criteria were systematically reviewed and assessed for quality and risk of bias. Results: The search identified 31 eligible articles, describing 29 trials. The included studies evaluated the use of computers to deliver cognitive rehabilitation (1 5 trials), patient education (3 trials), online self- management interventions (2 trials), and to support consultations (1 trial). Virtual reality (VR) was used to simulate work and social sit uations (2 trials ) and to deliver cognitive training (1 trial). Telephones were used to prompt medication use (3 trials ) and report SMI symptoms to healthcare teams (1 trial ). Remote sensors were used to monitor medication use (1 trial). Telephone support was found effective for improving medication adherence and reducing symptom severity and inpatient days. Computer assisted cognitive rehabilitation was effective in improving cognitive function. The impact of telehealth on other outcomes was inconsistent. Few studies evaluated the 3 use of remote medication telemonitoring, VR, online self-management and computer -mediated consultations, suggesting these are novel technologies for managing SMI, although all were found effective for improving psycho social and behavioural outcomes. The results of this review should be taken in the context of varied quality in study design, with only five studies demonstrating a low risk of bias. Conclusions : A growing variety of telehealth technologies are used to support SMI. Specific types of technology have been found to be effective for som e outcomes, for example telephone prompts for medication adherence, while other types of telehealth had no benefit over traditional methods and were less acceptable to patients. Few studies found benefits for telehealth on quality of life, except for novel technologies with a limited number of trials. Further research is warranted to establish the full potential benefits of telehealth for improving quality of life in SMI, acceptability from the service user perspective, and cost-effectivenes
