ROSS, an object-oriented language that has evolved over the last two years as part of the knowledge-based simulation research at Rand [1,3,6,7,8,91. We describe a program called SWIRL designed for simulating military air battles between offensive and defensive forces. SWIRL is written in an object-oriented language (ROSS) where the knowledge base consists of a set of objects and their In the fo...

In this paper, a Bayesian approach is proposed for shift point detection in an inverse Gaussian distribution. In this study, the mean parameter of inverse Gaussian distribution is assumed to be constant and shift points in shape parameter is considered. First the posterior distribution of shape parameter is obtained. Then the Bayes estimators are derived under a class of priors and using variou...

Choosing between two income distribution models typically involves testing two non-nested hypotheses, that is hypotheses such that one cannot be obtained as a special or limiting case of the other. Cox (1961, 1962) proposed a classical testing procedure based on the comparison of the maximized likelihood functions for the two models. In this paper it is shown that such a procedure is not robust...

In order to improve the approximation of spatial derivatives without meshes, a set of meshfree numerical schemes for derivative terms is developed, which is compatible with the coordinates of Cartesian, cylindrical, and spherical. Based on the comparisons between numerical and theoretical solutions, errors and convergences are assessed by a posteriori method, which shows that the approximations...

In this paper, we introduce the idea of -expansion by employing tri-simulation functions introduced Gubran et al. [R. Gubran, W. M. Alfaqih and Imdad, Italian Journal Pure Applied Mathematics -N, 45 (2021) 419-430] in a metric space. Further, shall use these mappings to study various fixed point results complete spaces. The paper generalize improve several on topic literature.
