FPGA BASED DESIGN FOR ACCELERATED FAULT-TESTING OF INTEGRATED CIRCUITS

In the past few decades, integrated circuits have become a major part of everyday life. Every circuit that is created needs to be tested for faults so faulty circuits are not sent to end-users. The creation of these tests is time consuming, costly and difficult to perform on larger circuits. This research presents a novel method for fault detection and test pattern reduction in integrated circuitry under test. By leveraging the FPGA's reconfigurability and parallel processing capabilities, a speed up in fault detection can be achieved over previous computer simulation techniques. This work presents the following contributions to the field of Stuck-At-Fault detection: We present a new method for inserting faults into a circuit net list. Given any circuit netlist, our tool can insert multiplexers into a circuit at correct internal nodes to aid in fault emulation on reconfigurable hardware. We present a parallel method of fault emulation. The benefit of the FPGA is not only its ability to implement any circuit, but its ability to process data in parallel. This research utilizes this to create a more efficient emulation method that implements numerous copies of the same circuit in the FPGA. A new method to organize the most efficient faults. Most methods for determinin the minimum number of inputs to cover the most faults require sophisticated softwareprograms that use heuristics. By utilizing hardware, this research is able to process data faster and use a simpler method for an efficient way of minimizing inputs.

Aging and Mental Health: Business as Usual?

Cautions that in developing training models in mental health and aging, psychologists must not overlook what experience has taught them about mental health intervention or what they know already about older adults. It is suggested that a life-span developmental view complements a community and preventive approach to the mental health needs of the elderly. Creation of a separate subspecialty of clinical geropsychology will not effectively serve older adults. What is needed is a synthesis ofalready existing expertise in areas such as life-span development, clinical psychology, and community psychology. This synthesis provides a conceptual foundation and set of intervention approaches on which to base training programs in mental health and aging.

Mental Health Problems and Aging: A Short Quiz.

The mental health needs of older adults remain largely unmet. This gap is due, in part, to a lack of adequately trained professionals and paraprofessionals. The sixteen-item quiz presented in this article has two purposes: 1) to present an overview of salient empirical and theoretical issues in the area of mental health and aging, and 2) to promote discussion of these topics. Each item is documented with supporting literature. In addition, average scores, item difficulties, and item-to-total correlations are presented for two groups of undergraduate students.

Life Transitions and Aging: Implications for Counseling Older Adults

Presents a conceptual framework for counseling older adults and their families, asserting that the pace of development varies across individuals and that within the same individual, different biological and psychological functions age at different rates. The normative changes of aging can be viewed as life-event/life-transition processes and categorized into 4 interrelated major areas: biological, psychological, environmental, and social/cultural. The counselor's tasks include assisting the older client in differentiating the normal aging process from abnormal processes, assessing the role of self-labeling and stereotyping, and focusing on preventive work with older adults and their families.

Aging and Social Policy: Contrasting Western Europe and the United States

In this essay, three generic issues that underlie our implicit social policy toward older adults and their families are considered: What is the proper division of responsibility for impaired elderly between family members and the state? Is age a morally relevant variable when allocating the resources of society? What should be the balance of competing demands between and among different generations? These issues are considered by contrasting the implicit and explicit policies of the United States with those of several Western European nations (Sweden, West Germany, Austria, and the Netherlands). Suggestions for a family-centered policy on aging are offered. In addition, indications for the appropriate blend of age and need as entitlement criteria are presented.

Mental Health and Aging: Progress and Prospects

This volume originally appeared as an issue of the ASA journal, Generations. It contains contributions by prestigious writers in the field of gerontology, who present current concepts in research and clinical practice on mental health and aging. This book provides the latest perspectives on assessment and prevention techniques, depressive and anxiety disorders, the aging brain and neuroimaging, family therapy, and adult day care.

Mental Disorders of Aging: An Emerging Public Health Crisis?

Focuses on the emergence of public health crisis in the U.S. in connection with the projected increase in the number of older adults with mental disorders. Disorders which are commonly associated with older adults; Sources of mental health services for older adults; Factors that contribute to high levels of psychopathology; Impact of the economic costs of mental disorders on direct and indirect costs for healthcare; Recommendations for the expected crisis in geriatric mental health.

Mental Health and Aging at the 2005 White House Conference on Aging: Two Steps Forward, One Step Back

Success! At the 2005 White House Conference on Aging, three-quarters of the 1,200 national delegates voted to improve “recognition, assessment, and treatment of mental illness and depression among older Americans.” This resulted in mental health being ranked as #8 of the final 50 WHCoA policy resolutions resulting from the conference. Joining this resolution in the “top ten” were two resolutions intimately tied to hopes for addressing the mental health needs of older adults—at #6 “Support Geriatric Education and Training for Health Care Professionals, Paraprofessionals, Health Profession Students and Direct Care Workers,” and #9 “Attain Adequate Numbers of Healthcare Personnel in All Professions Who are Skilled, Culturally Competent, and Specialized in Geriatrics.”

Aging and mental health in the decade ahead: What psychologists need to know

Until relatively recently, most psychologists have had limited professional involvement with older adults. With the baby boomers starting to turn 65 years old in 2011, sheer numbers of older adults will continue to increase. About 1 in 5 older adults has a mental disorder, such as dementia. Their needs for mental and behavioral health services are not now adequately met, and the decade ahead will require an approximate doubling of the current level of psychologists' time with older adults. Public policy in the coming decade will face tensions between cost containment and facilitation of integrated models of care. Most older adults who access mental health services do so in primary care settings, where interdisciplinary, collaborative models of care have been found to be quite effective. To meet the needs of the aging population, psychologists need to increase awareness of competencies for geropsychology practice and knowledge regarding dementia diagnosis, screening, and services. Opportunities for psychological practice are anticipated to grow in primary care, dementia and family caregiving services, decision-making-capacity evaluation, and end-of-life care. Aging is an aspect of diversity that can be integrated into psychology education across levels of training. Policy advocacy for geropsychology clinical services, education, and research remains critical. Psychologists have much to offer an aging society
