We present an effective technique for the combined performance and reliability analysis of multimode computer systems. A reward rate (or a performance level) is associated with each mode of operation. The switching between different modes is characterized by a continuoustime Markov chain. Different types of service-interruption interactions (as a result of mode switching) are considered. We con...

Recent advances in multi-million-gate platform FPGAs have made it possible to design and implement complex parallel systems on a programmable chip (PSOPCs) that also incorporate hardware floating-point units (FPUs). These options take advantage of resource reconfiguration. In contrast to the majority of the FPGA community that still employs reconfigurable logic to develop algorithm-specific cir...

Active database management systems(ADBMS) uses Event-Condition-Action rules (ECA rules). Each ECA rule speciies what action to be taken when an event occurs and the speciied condition is satissed. In this paper, we introduce a concurrency control scheme for handling nested cooperative transactions using detached mode ECA rules of an ADBMS. A state transition model has been proposed to specify d...

This paper presents a hybrid metaheuristic algorithm (HMA) for Multi-Mode Resource-Constrained Project Scheduling Problem (MRCPSP) in PERT networks. A PERT-type project, where activities require resources of various types with random duration, is considered. Each activity can be accomplished in one of several execution modes and each execution mode represents an alternative combination of resou...

Multimedia information availability has increased dramatically with the advent of video broadcasting on handheld devices. But with this availability comes problems of maintaining the security of information that is displayed in public. ISMA Encryption and Authentication (ISMACryp) is one of the chosen technologies for service protection in DVB-H (Digital Video BroadcastingHandheld), the TV syst...

Computation has been pushed to the edge decrease latency and alleviate computational burden of IoT applications in cloud. However, increasing processing demands make necessary employment platforms that exploit thread-level parallelism (TLP). Yet, power heat dissipation rise as TLP inadvertently increases or when is not cleverly exploited, which may be result nonideal use a given parallel progra...
