The nearly optimal, interoperable utilization of various grid resources play an important role in the world of grids. Though well-designed, evaluated and widely used resource brokers have been developed, these existing solutions still cannot cope with the high uncertainty ruling current grid systems. To ease the simultaneous utilization of different… (More)
Recently cloud computing is facing increasing attention as it is applied in many business scenarios by advertising the illusion of infinite resources towards its customers. Nevertheless, it raises severe issues with energy consumption: the higher levels of quality and availability require irrational energy expenditures. This paper proposes Pliant… (More)
The ever growing number of computation-intensive applications calls for the interoperation of distributed infrastructures such as Clouds, Grids and private clusters. The European SHIWA and ER-flow projects have been initiated to enable the combination of heterogeneous scientific workflows, and to execute them in a large-scale system consisting of multiple… (More)
Cloud Computing is facing an increasing attention nowadays as it is present in many consumer appliances by advertising the illusion of infinite resources towards its customers. Nevertheless it raises severe issues with energy consumption: the higher levels of quality and availability require irrational energy expenditures. This paper proposes a Pliant… (More)
In this paper we will present a new approach to approximate functions. The technology based on sigmoid function and Dombi operators. The main step is building a so called distending function of an interval to approximate the characteristic function. In this way we can compress the information of the function.
