the paper presents some guidelines supported by a case study of a design of a fault tolerant computer control system. It was devised and implemented as a laboratory platform for the 5th framework project IFATIS. Instead of the redundancy, in this project it is proposed to deal with faults by dynamic reconfiguration of the resources that are still viable after an incident. the goal of the design presented in this paper is to provide a consistent sophisticated distributed control system, tolerant to faults. In the paper, first general outlook of the IFATIS architecture is given. Based on that, hardware platform has been designed and implemented, together withthe system, application support and design software. the idea is to deal withthe faults on the lowest level and resolve them if possible in order to prevent the higher-level mechanisms to have to employ more costly measures.
the dynamic aspects of the object-oriented paradigm have prevented the adoption of the latter for the implementation of high integrity systems using the SPARK approach. this paper presents a proposal that allows objec...

Like many other enterprises, hospitals and healthcare organizations are now adopting networked information systemsthat incorporate heterogeneous hardware, software, and other elements (e.g., conceptual models). It is important to integrate these information systems developed independently by diverse set of people. Since healthcare involves very high level of diversity of knowledge, the interoperability of healthcare information systems poses some difficult problems. the task is challenging given the semantic differences of messages used by different types of healthcare professionals (e.g., physicians and nurses). We analyze the problem of interoperability with reference to different solutions, and present our experience in the development of a solution for the interoperability of clinical information systems based on HL7, CORBA and Java for a modern hospital in Australia.
Despite the increasing knowledge base within the IT industry worldwide about the tremendous benefits of XP and Agile processes, there is still a long way to go to convince a lot of developers. A side effect of this po...

In this paper, it is evaluated the electric field at the ground level of a 220 kV overhead transmission line and the corresponding busbars in a substation, under the capacitor bank switching-off effect. the simulation was performed using the EMTDC/PSCAD software package, to obtain the transient overvoltages in the transmission line and in the busbars. these computer programs present an efficient graphical user interface integrated with a time domain integration tool, which can be used successfully to simulate power system transients, including network control devices. It provides fast, accurate and flexible solutions, by applying the integration trapezoidal rule to solve the mathematical models. the electrical field was calculated using the CIGRE equivalent charge model. Finally some conclusions that provide a valuable contribution to the understanding of the electric field distribution in a substation due to the capacitor bank switching-off effect will be pointed out.
Many statechart-based testing strategies result in specifying a set of paths to be executed through a (flattened) statechart. these techniques can usually be easily automated so that the tester does not have to go thr...
