In this work we address the problem of arranging meetings for several participants taking into consideration constraints for personal agendas, transportation schedules and accommodation availability. We have implemented a multi-agent system that solves the problem. Building such applications implies to consider two main issues: collecting information from diierent sources on the Internet, and s...

We consider binary communication over the additive white Gaussian noise channel with no bandwidth constraint on the channel input signals, assuming the availability of a noiseless delayless feedback link. Although the signals at time t can depend on the noise at times 7 < t and are therefore random functions, we require that the signal energy never exceed a fixed level. We show that the optimal...

Summary: sORF finder is a program package for identifying small open reading frames (sORFs) with high coding potential. This application allows identification of coding sORFs according to the nucleotide composition bias among coding sequences and the potential functional constraint at the amino acid level through evaluation of synonymous and nonsynonymous substitution rates. Availability: Onlin...

Recently there has been considerable interest in the study of replica-control protocols which are based on organizing several copies of an object into logical structures, such as rectangular grids. In addition to high availability, another objective in exploiting such structures is to improve the degree of load sharing in a system. In this paper, we extend the scope of grid structures to genera...

a major constraint to the application of any form of knowledge and principles is the awareness, understanding and acceptance of the knowledge and principles. systems thinking (st) is a way of understanding and thinking about the nature of  health systems and how to make and implement decisions within health systems to maximize desired and minimize undesired effects. a major constraint to applyi...

Multi-constraint quality-of-service routing will become increasingly important as the Internet evolves to support real-time services. It is well known however, that optimum multi-constraint QoS routing is computationally complex, and for this reason various heuristics have been proposed for routing in practical situations. Among these methods, those that use a single mixed metric are the mo...

in this paper, we study different methods of solving joint redundancy-availability optimization for series-parallel systems with multi-state components. we analyzed various effective factors on system availability in order to determine the optimum number and version of components in each sub-system and consider the effects of improving failure rates of each component in each sub-system and impr...
