The paper presents results of the analysis of safety-critical embedded systems using a time triggered-architecture. First, a distributed safety-critical embedded system is defined in terms of its interfaces with the physical world, and possibilities of failures that can cause safety problems. Then, a model is built that allows mapping the safety functions to the time-triggered architecture. Finally,...
In this presentation, we discuss how a data warehouse can support situational awareness and data forensic needs for investigation of event streams violating rules. The data warehouse for event streams can contain summary tables showing rule violation on different aggregation level. We will introduce the classification of rules and the concept of a general aggregation graph for defining various classes...
The general requirements of information logistics are to provide the right information 'product', in the right format, at the right place, at the right time, and for the right people. In this paper we discuss two information logistics models: (a) hierarchical collaborative knowledge processing and (b) network collaborative knowledge processing. Ontology can be of crucial importance for information...
The paper describes a complex transportation system which can automatically respond to the situation when the driver becomes incapacitated. We have analyzed the solutions based on integration of two techniques: remote control and autonomous mode. We have concentrated our efforts on a handicapped vehicle system designed for an indoor environment. Determination of a level of a vehicle driver incapacitation...
