Optical transition radiation (OTR) imaging for transverse beam-size characterization is a well-established technique at many accelerators including the Fermilab A0 photoinjector (A0PI) facility. With low beam energies of 14-15 MeV and emittances of 3 mm mrad, one observes beam sizes of 0.8 to 1.5 mm (sigma). However, the use of 50-μm wide slits to sample the beam’s transverse phase spaces signi...

In all process Industries, to get quality product as output, the ingredients have to be composed in correct composition. So, to control quality of output product, we have to control the quantity of ingredients to be composed. In this paper, we have designed virtual Instrument which controls the process assessing the percentages of ingredients of any product using Lab VIEW. It checks whether add...

This paper presents an extended formulation of the unequal area facilities block layout problem which explicitly considers uncertainty in material handling costs by use of expected value and standard deviations of product forecasts. This formulation is solved using a random keys genetic algorithm (RKGA) heuristic with a flexible bay construct of the departments and total facility area. It is sh...

Background An effective emergency referral transport system is the link between the home of the pregnant woman and a health facility providing basic or comprehensive emergency obstetric care. This study attempts to explore the role of emergency transport associated with maternal deaths in Unnao district, Uttar Pradesh (UP).   Methods A descriptive study was carried out to assess the causes of a...

This essay explores the nature and implications of a type of inequality that is widespread, but largely ignored. Promises deliver important ethical value, and commercial promises, because they are our most common experience of promise with strangers, are of special value; but not all commercial promises generate that value equally. This paper makes the following claims: (1) while some retail pr...

Likert-type item is the most popular response format for collecting data in social, educational, and psychological studies through scales or questionnaires. However, there no consensus on whether parametric non-parametric tests should be preferred when analyzing data. This study examined statistical power of each was analyzed independently survey studies. The main purpose to examine Wilcoxon-Ma...

Income and class biases in political representation have attracted a great deal of scholarly attention recent years. The reasons are understandable: since the 1980s, very few democratically elected governments Organisation for Economic Cooperation Development (OECD) undertook new initiatives to compensate low- middle-income citizens unequal rise top-income shares concentration wealth. Instead, ...
