One of the principal motivations to use the grids computing and data grids comes from the applications using of large sets from data, for example, in High-Energy physics or Life Science to improve the total output of the software environments used to carry these applications on the grids, data replication are deposited on various selected sites. In the field of the grids the majority of the str...

The object of the study is process functioning enterprises grain product subcomplex. In course study, problem growth rate and peculiarities subcomplex were solved. An assessment was carried out Republic Kazakhstan using mathematical modeling, for which a methodology has been developed that allows considering factors with heterogeneous metric, includes following steps: 1) index analysis twenty-o...

1. Introduction. Nowadays, the bilevel optimization problems, arising in various applications [1, 2], seem to be one of the most attractive fields for many experts [1, 3, 4, 5]. Bilevel problems are such optimization problems, which – side by side with ordinary constraints such as equalities and inequalities [6] – include a constraint described as an optimization subproblem, called the lower-le...

Modeling and solving real world problems is one of the most important issues in optimization problems. In this paper, we present an approach to solve Fuzzy Interval Flexible Linear Programming (FIFLP) problems that simultaneously have the interval ambiguity in the matrix of coefficients .In the first step, using the interval problem solving techniques; we transform the fuzzy interval flexible p...

In humans, optimism is a cognitive construct related to motivation; optimists exert effort, whereas pessimists disengage from effort. In this study, using a recently developed ambiguous-cue interpretation (ACI) paradigm we took the unique opportunity to investigate whether "optimism" as a trait is correlated with motivation in rodents. In a series of ACI tests (cognitive bias screening, CBS), w...

The optimistic multigranulation T-fuzzy rough set model was established based on multiple granulations under T-fuzzy approximation space by Xu et al., 2012. From the reference, a natural idea is to consider pessimistic multigranulation model in T-fuzzy approximation space. So, in this paper, the main objective is to make further studies according to Xu et al., 2012. The optimistic multigranulat...

Large scale systems such as computational Grid is a distributed computing infrastructure that can provide globally available network resources. The evolution of information processing systems in Data Grid is characterized by a strong decentralization of data in several fields whose objective is to ensure the availability and the reliability of the data in the reason to provide a fault tolerance...

We propose a simple agent-based macroeconomic model in which firms hold heterogeneous sales expectations. A firm may either optimistically expect an increase in its sales or pessimistically expect the opposite. Whether a given firm is optimistic or pessimistic depends on macroeconomic conditions and the average mood prevailing within its social/local neighborhood. For instance, the probability ...
