Many applications, especially the ones implementing multiuser collaborative environments , fall within the context of soft real-time systems in which only small deviations from timing constraints are allowed. The advancements in distributed computing have made it possible to follow a service-oriented approach, taking advantage of the benefits this provides.(More)
We introduce a new model for objects which can move around on a cellular grid. The model consists of two phases, the movement phase and the connict resolution phase. In the movement part of the description objects specify their desired direction. The connict, which occurs when alternative objects want to move to the same free cell, is resolved in the(More)
Cellular Processing is an attractive and simple massive parallel processing model. To increase its general acceptance and usability it must be supported by a software environment, an eecient simulator and a special language. For this purpose the cellular description language CDL was deened and implemented. With CDL complex cellular algorithms can be(More)
The diphenylcarbazide colorimetric method was evaluated by analyzing spiked PVC filters prepared by an AIHA-accredited consultant laboratory for chromium (VI). All seven participating laboratories received the samples and performed the analyses at the same time. Three laboratories simultaneously tested three alternative analytical procedures. Reduced(More)
– Cellular Processing is based on the computational model cellular automata and includes an appropriate software environment. The model is massively parallel because all cells can compute their local rule in parallel. The paper gives an overview of the developed software and hardware support. The language CDL allows to describe complex rules with record(More)
