We study here $T_{0}$-$Q$-bitopological spaces and sober $Q$-bitopological spaces and their relationship with two particular Sierpinski objects in the category of $Q$-bitopological spaces. The epireflective hulls of both these Sierpinski objects in the category of $Q$-bitopological spaces turn out to be the category of $T_0$-$Q$-bitopological spaces. We show that only one of these Sierpinski ob...

هدف این تحقیق بررسی پیامدهای توانایی مدیریت شرکت­ها بر ارزش­ آفرینی در صنایع شیمیایی و مواد غذایی در دوره زمانی 1390-1394 با بکارگیری شبکه­ های عصبی مصنوعی است. ابتدا با اجرای مدل DEA با یک الگوی بومی شده، کارایی نسبی برای هر شرکت­ مشخص شده و با برآورد یک مدل رگرسیونی، شاخص توانایی مدیریت هر شرکت­ نیز تعیین شده است. سپس ارزش­آفرینی شرکت­ها از متوسط حاصل عواملی مانند بازده صاحبان سهام، نسبت Q تو...

The Padmakar-Ivan (PI) index of a graph G is the sum over all edges uv of G of the number of edges which are not equidistant from u and v. In this paper, the notion of vertex PI index of a graph is introduced. We apply this notion to compute an exact expression for the PI index of Cartesian product of graphs. This extends a result by Klavzar [On the PI index: PI-partitions and Cartesian product...

A questionnaire requiring respondents to rate the importance of key issues is the traditional data collection tool for investigating the key issues of Information Technology (IT) managers. Such an instrument does not force managers to confront the relationships between issues. Q-sort and interpretive structured modeling (ISM) force managers to consider the linkages among key issues. This articl...

By the time of Hippocrates the typical paroxysmal fever patterns of tertian (every 48 hours) and quartan (every 72 hours) fevers caused by malaria were known. Through the ensuing centuries, ancient Greek, Roman, and Persian physicians made additional contributions to the understanding of fevers. By the end of that era, there was a working definition of what constitutes a fever, the distinction ...
