BACKGROUND Accurate modeling of electrostatic potential and corresponding energies becomes increasingly important for understanding properties of biological macromolecules and their complexes. However, this is not an easy task due to the irregular shape of biological entities and the presence of water and mobile ions. RESULTS Here we report a comprehensive suite for the well-known Poisson-Bol...

This article is concerned with the pursuit of radical organizational transformation in information age government. It focuses on three cases, each of which used the SPRINT (Salford Process Reengineering Involving New Technology) process reengineering method. This method was designed specifically for e-government projects with the objective of inculcating radical change. Although each reported c...

Agent-oriented programming is a new area which extends the object-oriented concepts of encapsulated objects with the notions of beliefs, desires, intentions, teams, conversations etc. Deening an inheritance mechanism which will combine all these diierent aspects of agent languages into a uniform methodology for code re-use is a challenge. In this paper we give two diierent methodologies for re-...

This article presents a practical implementation of an ECG compression algorithm using a Max-Lloyd quantizer, to optimize the low resources of an ECG acquisition and transmission system (telemetry system) for dolphins and human divers. The algorithm scheme is based on a first-order differential pulse code modulation (DPCM) and uses a Max-Lloyd quantizer to code the difference between the curren...

In Distributed Storage Systems (DSSs), usually, data is stored using replicated packets on different chunk servers. Recently a new paradigm of Fractional Repetition (FR) codes have been introduced, in which, data is replicated in a smart way on distributed servers using a Maximum Distance Separable (MDS) code. In this work, for a non-uniform FR code, bounds on the FR code rate and DSS code rate...
