Simulation environments are analyzed from a software engineering point of view. Some basic ideas about a software architecture for simulation environments for hybrid systems are derived from recognizing that the simulation development process is a special case of the software development process. This view allows proven software engineering methods, techniques and tools to be applied to the dev...

With the advent of Software-Intensive and Cyber-Physical Systems, hybrid formalisms can be used to intuitively model the interactions of different models in different formalisms. Hybrid formalisms combine discrete (time/event) model constructs with continuous-time model constructs. These hybrid formalisms usually require a dedicated simulator. In this work we explicitly model the interfaces inv...

In the early days of microelectronic design, a top-to-down design fl ow was conceived to achieve the designs, while a bottom-up verifi cation path was used in order to check them during every stage of design with the aim of generating a series of EDA tools. In a near future, hybrid systems composed of nanometric CMOS transistors and nano-devices, such as the SET will also need the development o...

Recently hybrid modelling and simulation of biochemical systems have attracted increasing interest. This is motivated by the need of simulating systems which integrate different sub-cellular models, and the fact that bio networks themselves are inherently stochastic, however stochastic simulation is time expensive. Compared to other methods of biological modelling, Petri nets are characterized ...

The hybrid micro gird is growing due to the potential benefits in providing safe, reliable and sustainable electricity from renewable energy sources. In this paper, we are discussing the multiple energy sources i.e. PV/Fuel cell and wind based hybrid microgrid with help of simulation approach to improve the power quality in microgrid with ANN control. The artificial neural network control is us...

A hybrid molecular-dynamics (MD) and finite-element simulation approach is used to study stress distributions in silicon/silicon-nitride nanopixels. The hybrid approach provides atomistic description near the interface and continuum description deep into the substrate, increasing the accessible length scales and greatly reducing the computational cost. The results of the hybrid simulation are i...

Fault-tolerant control systems, i.e., systems that can continue operation even in case of faults, are attracting significant attention in academia and industry alike. Faulttolerant control systems are inherently hybrid, i.e., contain both continuous and discrete dynamics, and thus present problems in terms of both simulation and control synthesis. This paper presents an advanced application of ...

Process Management Model (PMM) and Process Simulation Model (PSM) are the critical infrastructural components of the Trustworthy Process Management Framework (TPMF), which involves a large and heterogeneous group of stakeholders in process modeling and simulation to improve process trustworthiness. Process Modeling Stakeholders (PMS) have different levels of dependency on various process modeli...

Real-time network simulation enables simulation to operate in real time, and in doing so allows experiments with simulated, emulated, and real network components acting in concert to test novel network applications or protocols. Real-time simulation can also run in parallel for large-scale network scenarios, in which case network traffic is represented as simulation events passed as messages to...

The simulation of large-scale inter-domain networks is useful for various aspects of network planning and management. It is also a challenge due to its scalability problems, and the often incomplete knowledge about the network in question. Automatic configuration of the simulator based on network measurements may also be required. None of the many proposed approaches to network simulation are s...
