Distribution System Restoration Based On Optimized Heuristic Search Method

Service recovery is still among the most essential approaches to enhance the durability of their contemporary distribution system. Following the error location is identified and isolated; a correct SR program ought to be ascertained to resupply out-of-service places. 2 heuristic approaches are suggested to locate an efficient and speedy solution in contemporary power supply systems. For resolving the support recovery issue in distribution systems, change selection indices sectionalizes switch stated by an analytic plan in addition to a practicable optimized heuristic graph-based process are given. The formulation of the issue includes four different functions like optimizing the complete load restored and cutting back the amount of changing operations. Maximizing the best priority restored loading, also decreasing load decreasing. A nice evaluation of change indices is used for many player tie sticks from the apparatus to think about the ideal solution and minimize the complete quantity of shifting operations. A brand new graph-based program may be used for hunting the best sectionalizes change and diminishing the voltage fall. The precision as well as the validity of this process are analyzed in two regular electrical supply procedures. The outcomes of these suggested methods are utilized for IEEE regular bus test instance

Epidemiology of neurodegenerative diseases in sub-Saharan Africa: a systematic review

BACKGROUND:Sub-Saharan African (SSA) countries are experiencing rapid transitions with increased life expectancy. As a result the burden of age-related conditions such as neurodegenerative diseases might be increasing. We conducted a systematic review of published studies on common neurodegenerative diseases, and HIV-related neurocognitive impairment in SSA, in order to identify research gaps and inform prevention and control solutions. METHODS: We searched MEDLINE via PubMed, 'Banque de Donnees de Sante Publique' and the database of the 'Institut d'Epidemiologie Neurologique et de Neurologie Tropicale' from inception to February 2013 for published original studies from SSA on neurodegenerative diseases and HIV-related neurocognitive impairment. Screening and data extraction were conducted by two investigators. Bibliographies and citations of eligible studies were investigated. RESULTS: In all 144 publications reporting on dementia (n=49 publications, mainly Alzheimer disease), Parkinsonism (PD, n=20), HIV-related neurocognitive impairment (n=47), Huntington disease (HD, n=19), amyotrophic lateral sclerosis (ALS, n=15), cerebellar degeneration (n=4) and Lewy body dementia (n=1). Of these studies, largely based on prevalent cases from retrospective data on urban populations, half originated from Nigeria and South Africa. The prevalence of dementia (Alzheimer disease) varied between <1% and 10.1% (0.7% and 5.6%) in population-based studies and from <1% to 47.8% in hospital-based studies. Incidence of dementia (Alzheimer disease) ranged from 8.7 to 21.8/1000/year (9.5 to 11.1), and major risk factors were advanced age and female sex. HIV-related neurocognitive impairment's prevalence (all from hospital-based studies) ranged from <1% to 80%. Population-based prevalence of PD and ALS varied from 10 to 235/100,000, and from 5 to 15/100,000 respectively while that for Huntington disease was 3.5/100,000. Equivalent figures for hospital based studies were the following: PD (0.41 to 7.2%), ALS (0.2 to 8.0/1000), and HD (0.2/100,000 to 46.0/100,000). CONCLUSIONS: The body of literature on neurodegenerative disorders in SSA is large with regard to dementia and HIV-related neurocognitive disorders but limited for other neurodegenerative disorders. Shortcomings include few population-based studies, heterogeneous diagnostic criteria and uneven representation of countries on the continent. There are important knowledge gaps that need urgent action, in order to prepare the sub-continent for the anticipated local surge in neurodegenerative diseases

Psychometric Properties and Correlates of Precarious Manhood Beliefs in 62 Nations

Precarious manhood beliefs portray manhood, relative to womanhood, as a social status that is hard to earn, easy to lose, and proven via public action. Here, we present cross-cultural data on a brief measure of precarious manhood beliefs (the Precarious Manhood Beliefs scale [PMB]) that covaries meaningfully with other cross-culturally validated gender ideologies and with country-level indices of gender equality and human development. Using data from university samples in 62 countries across 13 world regions (N = 33,417), we demonstrate: (1) the psychometric isomorphism of the PMB (i.e., its comparability in meaning and statistical properties across the individual and country levels); (2) the PMB’s distinctness from, and associations with, ambivalent sexism and ambivalence toward men; and (3) associations of the PMB with nation-level gender equality and human development. Findings are discussed in terms of their statistical and theoretical implications for understanding widely-held beliefs about the precariousness of the male gender role

Isıl enerji depolamalı parabolik oluklu kolektörlerin modellenmesi, zamana bağlı benzetimi ve parametrik çalışması.

In this thesis, a mathematical model of a parabolic trough collector field with a two-tank molten salt thermal energy storage is developed. The model is built in TRNSYS and by using MatLab, novel valve and thermal energy storage control algorithms are implemented. The model is sensitive to transient states inside the components and variations in weather and demand. Optimum parabolic trough collector length is determined for different insolation values to show the relation between direct normal insolation and collector string length. The mathematical model is used in an economic model, which contains initial investment costs of the parabolic trough collector field and thermal energy storage costs only. Depending on the economic model, different sizes of plants are created at fixed initial investment costs by changing collector field area and storage size in the mathematical model. A parametric study is done by using economic model data and by simulating the mathematical model at various initial investment costs, two different locations in Turkey, and four different load profiles. As result of the parametric study, maximum solar fraction cases are selected and a generalized trend is observed. Effect of thermal energy storage on solar fraction is discussed and the change in thermal energy storage with optimum plant size is investigated. After an optimum investment, linear increment behavior of solar fraction is disappears and increases asymptotically by increasing the plant and/or storage size. Above this limit, hybridizing with other energy sources are advised. Later in the thesis, significance of load profile is emphasized, which should be one of the major design parameters for solar powered energy systems.M.S. - Master of Scienc
