With the advent of the Web along with the unprecedented amount of information coming from sources of heterogeneous data, Formal Concept Analysis (FCA) is more useful and practical than ever, because this technology addresses important limitations of the systems that currently support users in their quest for information. In this paper, we will focus on the unique features of FCA for searching i...

This paper investigates the relationship between systems to enact software processes and systems to coordinate distributed, heterogeneous and concurrent objects. In particular, we describe in detail how one of these coordination systems systems—the “Coordination Language Facility” (CLF), developed at the Rank Xerox Research Centre—can be used to model and execute a sample software development p...

Distributed systems tend to be heterogeneous, especially when they are not under the same administration. Distributed multimedia services need a widely spread distribution to be of interest to a user. Only if the multimedia services are accessible everywhere in any environment they will be acceptable. To cover heterogeneity and flexible service deployment mobile agents can be used. They configu...

InfoSleuth is an agent-based system that can be configured to perform many different information management activities in a distributed environment. InfoSleuth agents provide a number of complex query services that require resolving ontology-based queries over dynamically changing, distributed, heterogeneous resources. These include distributed query processing, locationindependent single-resou...

Distributed computing systems often consist of heterogeneous computing resources managed by different administrators. Due to the distributed nature, effective management of the resources may become difficult and the performance of the system may be affected. Also, the users of distributed systems may be self-interested whose goal would be to maximize their own utility. Such selfinterested agent...

This report describes the riso project, a system for uniied prediction and diagnosis in HVAC systems based on a class of probabilistic models called belief networks. Progress has been made in both theoretical and practical problems: a scheme for the representation of belief networks with heterogeneous conditional distributions has been devised, an algorithm for inference in a polytree network w...

A generalized simplified model for describing the dynamic behavior of distributed parameter systems is proposed. The various specific characteristics of gain and phase angle of distributed parameter systems are investigated from frequency response formulation and complex plane representation of the proposed simplified model. The complex plane investigation renders some important inequality cons...

Distributed storage systems are mainly justified due to their ability to store data reliably over some unreliable nodes such that the system can have long term durability. Recently, regenerating codes are proposed to make a balance between the repair bandwidth and the storage capacity per node. This is achieved through using the notion of network coding approach. In this paper, a new variation ...

—This papers deals with a new task scheduling algorithm for distributed heterogeneous computing environments. In distributed and parallel computing system, efficient task scheduling of computationally intensive applications is one of the most essential and difficult issues. Although a large number of scheduling heuristics have been presented in the literature, most of them target only homogeneo...
