In the open telecommunication market characterised by deregulation and global competition, new technology is constantly being introduced into products, systems and networks. Network providers build networks that consist of products from multiple vendors; service providers are faced with the challenge of providing services over heterogeneous computing and network environments. Achieving interope...

As systems become increasingly connected to an increasingly diverse set of other systems and environments, architects will lose their ability to intricately plan interactions among system components, because an increasing fraction of those interactions will be with foreign and possibly unanticipated systems or components. Humans will be increasingly less competent to install, configure, optimiz...

We discuss a class of matrix models describing cosmology with a light-like singularity, generalizing the model proposed by Craps et al. in hep-th/0506180.

E-learning takes advantage of the new features offered by Web services: integration of heterogeneous applications, publicity of available services, etc. As the adoption of this new technology increases it will become necessary to offer intermediary platforms that make it easier to find and locate services, and composing new services from the existing ones. Additionally, it will also be necessar...

An efficient assignment and scheduling of tasks is one of the key elements in effective utilization of heterogeneous multiprocessor systems. The task scheduling problem has been proven to be NP-hard is the reason why we used meta-heuristic methods for finding a suboptimal schedule. In this paper we proposed a new approach using TRIZ (specially 40 inventive principles). The basic idea of thi...

This paper considers the Heterogeneous Earliest Finish Time (HEFT) algorithm for scheduling the tasks of an application, represented by a directed acyclic graph, onto a bounded number of heterogeneous machines. We focus on the appropriate selection of the weight for the nodes and edges of the graph, and experiment with a number of different schemes for computing these weights. Our findings indi...

hnRNP K protein, which localizes to the nucleus, cytoplasm and mitochondria, is involved in the various cellular processes that compose gene expression. We used a SAGE-based assay to profile RNAs associated with hnRNP K protein in rat mitochondria. RNA was isolated from mitoplasts obtained from highly purified and RNase-treated mitochondria. Total RNA and RNA associated with hnRNP K protein wer...
