A conceptual framework is proposed for a digital environment extending from the prototype design of nuclear plants through operations and decommissioning to storage and waste disposal. The environment consists of a series of interconnected multi-scale, multi-physics computational models linked to the real-world by data acquired during validation of prototypes, in-service monitoring and inspections...
Predicting the capacity of wireless mesh networks is difficult, due to the complex interaction of various layers such as the radio environment, media access protocols, network protocols and, traffic load and types. When modelling and simulation takes into account the interaction of all these factors, it can facilitate insights into anticipated network behaviour. These insights can be used to more...
The following topics are dealt with: hybrid and electric vehicles; subsystems and components; control; infrastructure; real world experience; policy; reliability and safety; modelling and simulation.
Network availability is an essential feature of an optical telecommunication network. Should a failure of a network component occur, be it a link or a component inside a node, network control plane must be able to detect the failure and reroute the traffic using spare components until a repair is done. Shared risk link groups (SRLGs) are used to describe a situation where seemingly unrelated logical...
The submodel technique was mainly developed in mechanical engineering for complex parts and assemblies. In the simulations of microelectronics housing the technique was successful implemented for thermal cycling conditions. In thispaper the evaluation of the submodel technique for power electronic packages under power cycling conditions will be discussed.
The paper describes the design goals and methodology in creating a new model of optical telecommunication network. The model is implemented by discrete-event network simulator ns-3. The advantages of using the existing simulator core infrastructure provided by ns-3 are analyzed and compared to building own simulator from scratch, or selecting a tool among other existing simulators such as ns-2, OMNeT++,...
The following topics are dealt with: vehicular networking; beaconing and broadcast; data collection and management; simulation and modelling; transport protocols; mobility management in VANETs; telecommunication security; smart antennas and radio; reliability and routing; cellular networks; physical layer; and MAC.
In this paper a probabilistic reliability analysis approach at high confidence level is presented that employs the modeling and simulations techniques. This not only reduces the cost of testing, but also predicts the physics-of-failures, response of system and quantifies the uncertainty in loading environment. Probabilistic sensitivities may be determined to assess the relative importance of each...
Hardware fault-insertion test (FIT) is a promising method for system reliability test and diagnosis coverage measurement. It improves the speed of releasing a quality diagnostic program before manufacturing and provides feedbacks of fault tolerance of a very complicated large system. Certain level insufficient fault tolerance can be fixed in the current system but others may require ASIC or overall...
