through the last three decades different seismological and engineering approaches for the generation of artificial earthquakes have been proposed. selection of an appropriate method for the generation of applicable artificial earthquake accelerograms (aeas) has been a challenging subject in the time history analysis of the structures in the case of the absence of sufficient recorded accelerogra...

A stochastic hybrid system contains a collection of interacting discrete and continuous components, subject to random behaviour. The formal verification of a stochastic hybrid system often comprises a method for the generation of a finite-state probabilistic system which either represents exactly the behaviour of the stochastic hybrid system, or which approximates conservatively its behaviour. ...

In previous studies, active suspension system in conventional powertrain systems was investigated. This paper presents the application of active suspension system in parallel hybrid electric vehicles as a novel idea. The main motivation for this study is investigation of the potential advantages of this application over the conventional one. For this purpose, a simultaneous simulation is develo...

In this paper, we address parameter estimation for hybrid dynamical systems with statedependent events and time-delayed parametric switching. Parameter estimation of hybrid systems can aid in system identification, model refinement, and contingency and stability analysis in various fields, including chemical, electrical, and power systems engineering. We discuss parameter estimation for hybrid ...

A hierarchical test generation approach for digital systems which uses register-transfer (RT) and gate level system descriptions is presented. Decision diagrams are exploited as a uniform model for describing systems at different representation levels. The method combines bottom-up and top-down approaches to make hierarchical test generation more efficient by a synergism of deterministic and ra...

Our paper focuses on the generation of optimal test sequences and test cases using Intelligent Agents for highly reliable systems. Test sequences support test case generation for these types of systems. Our system is modeled through UML state charts. Conventional test generation techniques do not worry about optimization and dynamic nature of such systems. In the case of highly reliable Softwar...

Output power in a hybrid power system is constant while the input power with variable characteristics that is generated by different sources. Using Hybrid Electrical Energy Storage (HEES) systems, is growing rapidly since there is an obvious need for clean energy. This paper introduces different parts of a HEES system and then proposes HEES systems which employ battery, ultracapacitor and f...

Hybrid system is a dynamic system that exhibits both continuous and discrete dynamic behavior‎. ‎The hybrid differential equations have a wide range of applications in science and engineering‎. ‎The hybrid systems are devoted to modeling‎, ‎design‎, ‎and validation of interactive systems of computer programs and continuous systems‎. ‎Hybrid fuzzy differential equations (HFDEs) is considered by ...

This paper provides a specification of requirements for collocation extraction systems, taking as an example the extraction of noun + verb collocations from German texts. A hybrid approach to the extraction of habitual collocations and idioms is presented, aiming at a detailed description of collocations and their morphosyntax for natural language generation systems as well as to support learne...
