Abstract. In this paper, we define the notion of C*-affine maps in the unital *-rings and we investigate the C*-extreme points of the graph and epigraph of such maps. We show that for a C*-convex map f on a unital *-ring R satisfying the positive square root axiom with an additional condition, the graph of f is a C*-face of the epigraph of f. Moreover, we prove som...
Conventional data envelopment analysis (DEA) assists decision makers in distinguishing between efficient and inefficient decision making units (DMUs) in a homogeneous group. However, DEA does not provide more information about the efficient DMUs. One of the interesting research subjects is to discriminate between efficient DMUs. The aim of this paper is ranking all efficient (extreme and non-ex...
Introduction Climate change is the greatest price society is paying for decades of environmental neglect. The impact of global warming is most visible in the rising threat of climate-related natural disasters. Globally, meteorological disasters more than doubled, from an average of forty-five events a year to almost 120 events a year (Vinod, 2017). Climate change refers to changes in the distr...
temperature is one of the essential elements of forming a climate and plays a crucial role in the lives of flora, fauna and human activities. the extreme temperature is one of the thermal indexes in meteorological and climatological studies. the extreme temperature is divided into two types: the extreme warm and extreme cold. the extreme warm includes the temperatures much above the normal valu...
Background. Over the last few decades, an increasing number of studies have suggested a connection between neurodevelopmental problems (NDPs) and body mass index (BMI). Attention deficit/hyperactivity disorder (ADHD) and autism spectrum disorders (ASD) both seem to carry an increased risk for developing extreme BMI. However, the results are inconsistent, and there have been only a few studies o...
Climatic extremes are the special status (high or low) of climatic elements. In spite of the unique definition, there are a lot of thresholds which have been illustrated for extremes. For example, Bonneted (2006) has defined the climatic extremes as intensive and abnormal events that include the lowest and highest values in a time series. Becker et al. (2007) have referred to the extremes of cl...
This paper explores Extreme Programming (XP) as an information systems development approach and argues that it is mainly old wine in new bottles. We take an interpretive and critical view of the phenomenon. We made an empirical study of two companies that apply an XP style development approach throughout the information systems development lifecycle. The results of our research suggest that XP ...
Increasing CO2 emissions and consequently, air temperature causes climate anomalies which affects all the aspects of human life. The purpose of this study was to assess the temperature changes and also to predict the extreme temperatures in Gilan and Mazandaran Provinces. To do this, the SDSM statistical and dynamical model was used. As well, it was applied the Mann-Kendal graphical and statist...
deviding both the subjects and the predicates of the categorical propositions into actuality and verity, afzal al-din khunaji states the actuality-parts as adjectives, but verity-parts in three forms: as simple, as relational and as conditional. since the adjectives are formulated in modern logic by conjunction, we can formulate actuality-parts as conjunctions. verity-parts can be formulated at...
