    Summary form only given. Real-time simulation, in which the behaviour of a simulation of a system develops in precisely the same time-scale as the corresponding behaviour of the system itself, has been used for many years for testing hardware (hardware-in-the-loop or HIL), software and for training (e.g. flight simulators, power-plant simulators). The two distinguishing features of real-time simul... View full abstract»

    Real-time simulation has been used since the early days of computer simulation. Current real-time operating systems can support real-time simulations with frame times as short as hundreds of microseconds. Some applications are now emerging that need shorter frame times, as low as 1 microsecond. New techniques are required for these high-speed real-time (HSRT) simulations. One approach is based on ...

    Static synchronous series compensator (SSSC) is widely used in power systems to control power of power system by injecting appropriate reactive power into the system. It also has the capability of improving stability and damping by dynamically controlling its reactive power output. This paper presents the energy function of a power system with a SSSC. The proposed energy function is used for trans... View full abstract»

    A mobile ad hoc network (MANET) is one consisting of a set of mobile hosts capable of communicating with each other without the assistance of base stations. Earlier research has proposed several unipath routing protocols specifically on MANET, but most studies have not focused on the limitations of battery resource. To alleviate these problems, a new routing protocol called energy-aware grid multi... View full abstract»

    In this paper the derivation of mathematical model of a horizontal active magnetic bearing (AMB) system in deterministic form is presented. The system is open-loop unstable and highly coupled due to nonlinearities inherited in the system such as gyroscopic effect and mass imbalance. Based on the equation of motions of the rotor and dynamic equation of electromagnetic coils, the dynamic model of th... View full abstract»

    Replacing the aging instrumentation and control system (I&C) in a nuclear power plant (NPP) is always a difficult task, even without the present energy-distribution disturbances in Europe and the more and more frequent plant-life-extension and power-up-rating projects. The NPP plant life-cycle tends to reach 50-60 years, while that of the I&C system is only 8-10 years. Not only the systems... View full abstract»

    The Paks full-scope training simulator has been in service since 1988. In the last almost two decades practically every element of the simulator has been upgraded, replaced because the fast development of the computer techniques made the solution a great amount earlier unsolvable problems possible. Moreover, the requirements against the simulator have also changed. Originally the simulator was use... View full abstract»

    Fusion energy research has reached a state, where a transition from laboratory scale physics experiments to industrial scale reactors is necessary and possible. Current devices can routinely reach plasma conditions needed for a fusion reactor, but positive energy balance can only be achieved by increasing the machine size by about a factor of two above the currently largest device JET. Although th... View full abstract»

    The new IETF protocol ENUM uses the DNS to bind existing phone numbers into set of information's (email address, SIP phone number etc.). Success of ENUM will depend on whether the DNS can achieve a performance similar to the database used in classical voice services. In order to study the DNS performance we designed a new way to measure and model a single DNS server behavior. We also modeled and m... View full abstract»

  • Modelling Internet End-to-End Loss Behaviours: A New Approach

    This paper proposes a new approach to modelling Internet end-to-end loss behaviours. Rather than select the model structure from the loss observations like being done previously, we construct a new loss model based on the TCP congestion control mechanism. Thus, the model can explicitly reflect the correlation between end-to-end loss observations and network flow level activities. Besides simulatio... View full abstract»

    Web service modeling research is largely limited to service conversation i.e. choreography. Recently, we have proposed a method to model both service orchestration and choreography using a FSM. But a flat approach (i.e. modeling at one level only) is not suitable to represent a large and complex service process. For the purpose, we propose a method to model Web services using FSM modules. And show... View full abstract»
