Introduction In the theory of reliability and life testing analysis the exponential distribution has a great importance. The main features of the utility of the distribution are its positive ranges its property of forgetfulness and the graphic shape of the distribution. It has a mirror shape J when plotted on the range of random variable x , at Χ-axis with respect …Read More »

Introduction In the last four decades, several authors discussed the commutativity of the prime rings and the semiprime rings that admitting automorphisms, derivations or generalized derivations that are centralizing or commuting on an appropriate subset of R (see , , , ,  and ). Related concepts such as σ -prime rings and Lie structure of prime rings with generalized …Read More »
Complex Decision Making by Complex Decision Making by use of Ahp: Case Studies Based on Kakda Rolling Mills Use of Ahp: Case Studies Based on Kakda Rolling Mills
Introduction The analytic hierarchy process (ahp) is a structured technique to help people in deal with complex decisions rather than prescribing a “correct” decision. the ahp helps people to determine one from many. based on mathematic and human psychology, it was developed by thomas l. saaty in the 1970s and has been extensively studied and refined since then. the ahp …Read More »
Introduction Earlier there were only experimental techniques available to predict the performance of turbo machinery and calculating the losses in flowing fluid even in pipes. The experiments were done on models. But observation of behaviour of flow was very difficult to observe and studying local parameters was very difficult . With the advances in the field of computational mathematics and …Read More »
Introduction To begin with, let’s see what many scholars have to say about soft skills. According to (Schulz, 2007), soft skills complement hard skills and play an important role in shaping an individual. Further, hard and soft skills together constitute professional competence of an individual which allows a goal-oriented and situational accomplishment of working tasks (Kauffeld, Grote, & Frieling, 2003).Further, …Read More »
