In complex real-time applications, real-time systems handle significant amounts of information that must be managed efficiently, motivating the need for incorporating realtime database management into real-time systems. However, resource management in realtime database systems is a complex issue. Since these systems often operate in environments of imminent and transient overloads, efficient ov...

Management of workkow processes is more than just enactment of process activities according to business rules. Time management func-tionality should be provided to control the lifecycle of processes. Time management should address planning of workkow executions in time, provide various estimates about activity execution durations, avoid violations of deadlines assigned to activities and the ent...

This paper presents the requirements for just in time knowledge management (JIT-KM). In order to deliver high-value information to user for decision-making, one must understand the user’s preferences, biases and decision context. A JIT-KM architecture is presented consisting of user, middleware and data services to search for information from heterogeneous sources, and to rank and deliver this ...

As the frequency of attacks faced by the average host connected to the Internet increases, reliance on manual intervention for response is decreasingly tenable. Operating system and application based mechanisms for automated response are increasingly needed. Existing solutions have either been customized to specific attacks, such as disabling an account after a number of authentication failures...

Temporal conformance of web service compositions guarantees the timely execution of service calls, decreases follow-up costs and increases QoS by avoiding deadline violations. Since it is impossible to make certain statements about the execution intervals of upcoming web service executions mainly due to varying activity durations and hardto-predict branching behavior we propose a probabilistic ...

Time management is one of the critical modules of safety-critical systems. Applications need strong assurance from the operating system that their hard real-time requirements are met. Partitioned system has recently evolved as a means to provide protection to safety critical applications running on an Avionics computer resource. Each partition has an application running strictly for a specified...

E-learning is a technology supposed to make learning and teaching easier. This paper deals with the question whether it is really true, i.e. if the same educational outcome consumes more or less time than classic teaching methods. From the observation flows that e-learning technologies, as well as other information and communication technologies, can consume inadequate time portion if used impr...

This presentation describes an embedded intelligent agent architecture for distributing the realtime allocation and management of resources throughout networked systems. The solution is general purpose, and has been developed for several applications, including shared electronic systems and spectrum allocation. The agent architecture was derived from a combination of prior agent and resource ma...
