Distributed computing systems are a viable and less expensive alternative to parallel computers. However, a serious difficulty in concurrent programming of a distributed system is how to deal with scheduling and load balancing of such a system which may consist of heterogeneous computers. Some distributed scheduling schemes suitable for parallel loops with independent iterations on heterogeneou...

Networked heterogeneous systems pose a great challenge for parallel and distributed applications. Middleware provides a critical link between the vast resources and the application domain that simplifies development, provides robust and reliable access to resources, helps optimize resource utilization, and facilitates the generation of stable distributed software. In this paper, we discuss a la...

abstract this paper presents a multiobjective power control algorithm that updates the transmitted power based on local information. the proposed algorithm is expanded by using multiobjective optimization schemes. the objectives to be optimized in this paper are determined so as to reduce the sinr fluctuations as well as maintaining the sinr to an acceptable level with minimizing an average tra...

As a computing environment evolves, heterogeneous and distributed computing environments are often unavoidable. Companies are willing to retain their legacy systems and also acquire new types of systems for their daily business operations. Rewrite, facelift and convert are three common ways to address legacy integration for use in heterogeneous and distributed computing environments. Rewrite an...

This work deals with cooperation of heterogeneous Information Systems. The growth and variety of distributed information sources imply a need to exchange and/or to share information extracted from various and heterogeneous databases. Cooperation of heterogeneous information systems requires advanced architectures able to solve conflicts coming from data heterogeneity. The project ACSIS (Agents ...

in the present study, a heterogeneous and homogeneous gas flow dispersion model for simulation and optimization of a large-scale catalytic slurry reactor for the direct synthesis of dimethyl ether (dme) from synthesis gas (syngas) and co2, using a churn-turbulent regime was developed. in the heterogeneous flow model, the gas phase was distributed into two bubble phases including small and large...
