Massive Multiuser Virtual Environments (MMVEs) are rapidly expanding both in the number of users and complexity of interactions. Their needs of computational resources offer new challenges for the computer scientists. In this paper we present an implementation and some early tests of a Massive Simulation Environments, a particular MMVE, distributed over a Peer-to-Peer infrastructure. We provide...

Proper planning of assembly lines is one of the production managers’ concerns at the tactical level so that it would be possible to use the machine capacity, reduce operating costs and deliver customer orders on time. The lack of an efficient method in balancing assembly line can create threatening problems for manufacturing organizations. The use of assembly line balancing methods cannot balan...

one studies the $hx$-hypergroups, corresponding to the chinese hypergroups associated with the direct products of some ${bf z}/n {bf z},$ calculating their fuzzy grades.

in this study we have described our varicocele cases in terms of associated symptoms/signs. in addition, we have tested the correlation between semen parameters and varicocele grades and compared the relative frequencies of associated symptoms/signs in different varicocele grades. 1 19 referred cases of varicocele were categorized based on clinical criteria into 3 grades by one examiner. the re...

Assembly lines are special kinds of production systems which are of great importance in the industrial production of high quantity commodities. In many practical manufacturing systems, configuration of assembly lines is fixed and designing a new line may be incurred huge amount of costs and thereby it is not desirable for practitioners. When some changes related to market demand occur, it is wo...

The study complements previous research on a case of chemistry lesson plans design and teaching. It has been found that education in Gambia challenged by ineffective teaching, laboratory resources. consequences have unsatisfactory learning outcomes. However, what could lead to outcomes if basic stoichiometry is considered challenging? This led the present develop survey method assess students' ...

Abstract The aim of this article is to investigate two new classes quaternions, namely, balancing and Lucas-balancing quaternions that are based on numbers, respectively. Further, some identities including Binet’s formulas, summation Catalan’s identity, etc. concerning these also established.
