In this paper, we present a game theoretic framework for obtaining a user-optimal load balancing scheme in heterogeneous distributed systems. We formulate the static load balancing problem in heterogeneous distributed systems as a noncooperative game among users. For the proposed noncooperative load balancing game, we present the structure of the Nash equilibrium. Based on this structure we der...

each semester, students are asked to evaluate the academic staff through an online questionnaire. generalized estimating equations model (gee), taking into account the correlation between scores, is the established tool to analyze longitudinal data. the aim of this manuscript is to identify characteristics that influence staff score and to address the importance of selection of appropriate corr...

Distributed Processing Programming Executive (DPPx) is a new, full-function operating system designed to support distributed processing with the IBM 8100 Information System. The functional requirements of distributed processing and their solutions in D p P x are discussed. The structure of the operating system is outlined, and its advantages are analyzed. Highlighted are particular characte...

The paper contains description of distributed XML store model based on notion of distributed XML document. Classification of XPath expressions is defined and the notion of distributed XML document is introduced. Definition of DataGuide-based statistical structure for XML stores is proposed and two possible approaches to maintain its actuality are discussed. Stability of feedback-based approach ...

Change regions approximate dynamic instance nonmigratability through schema based approach. In a distributed process, each node may have a partial view of the structure of the whole process. The distributed structure-fragments may evolve independently at runtime. Established centralized algorithms to compute change regions cannot be directly applied to such a scenario, due to absence of a centr...

Background: Mushroom Tyrosinase a potent candidate in clinical studies known as polyphenol oxidase, is a metaloenzyme from the oxidase superfamily widely distributed from lower to higher life forms. It plays a crucial role in sclerotization of exoskeleton in insects, also responsible for skin pigmentation in mammalians. Objective: In this study, after reconstitution of MT by some metal io...

in this article, thermo-elastic-behavior of a thick-walled cylinder made from a polystyrene nanocomposite reinforced with functionally graded (fg) single-walled carbon nanotubes (swcnts) was carried out in radial direction while subjected to a steady state thermal field. the swcnts were assumed aligned, straight with infinite length and a uniform layout. two types of variations in the volume fr...

In this study, functionally graded Ni-Al2O3 composite coating (FGN-A) has been produced from nickel Watt’s bath containing different concentrations of Al2O3 particles. For this, different composite coatings were electroplated in the same bath with different particles concentration to find the optimum concentration of particles in which the maximum content with uniform distribution of Al2O3 part...
