Seismic performance of substation equipment during past earthquakes is poor. In addition, requirement electric power post-earthquake led to an increased focus on the earthquake survivability equipment. Equipment installed in vulnerable by virtue its geometry and configuration. Interconnection between further aggravates problem. Failure results financial loss considerable time required repair/re...

Component-based software performance engineering (CBSPE) methods shall enable software architects to assess the expected response times, throughputs, and resource utilization of their systems already during design. This avoids the violation of performance requirements. Existing approaches for CBSPE either lack tool support or rely on prototypical tools, who have only been applied by their autho...

Model-driven performance prediction methods require detailed design models to evaluate the performance of software systems during early development stages. However, the complexity of detailed prediction models and the semantic gap between modelled performance concerns and functional concerns prevents many developers to address performance. As a solution to this problem, systematic model refinem...

Next generation Software Performance Engineering tools will exploit a model interoperability paradigm that uses the performance modeling tool best suited to the software/hardware architecture issues and the life cycle stage of the assessment. The paradigm allows the use of existing tools to the extent possible without requiring extensive changes to them. The performance model solution should be...

I declare that I have developed and written the enclosed Study Thesis completely by myself, and have not used sources or means without declaration in the text. Design time performance prediction is an important aspect in the field of component-based software performance engineering. Especially in early development stages the model is on a high abstraction level and precise predictions are diffi...

This paper presents a probabilistic approach for the design and assessment of structural elements under blast loads. The procedure is based on the broadly adopted fragility analysis method, widely implemented in Performance-Based Design procedures for structures subjected to natural hazards such as earthquake and wind. A discussion on the uncertainties related to blast engineering problems and ...

The development of design seismic forces is reviewed. The earthquake engineering was shown to have developed in the last 60 years. The characteristics of ground motion and structural response were gradually understood over the last five decades. The damage statistics from recent major earthquakes indicated that the severe damage was observed in taller buildings. The ratios of buildings with ope...

The main objective of this research project is to residual deformation and collapse mechanism of structural system and to assess the seismic demand of this system. In this study three major works are developed: a. Develop a physical-based inelastic hysteretic model which contains stiffness and strength degradation, pinching and residual deformation, b. Based on the proposed model the seismic de...

Component Based Software Engineering (CBSE) exploits re-usability of configurable components to generate software products more quickly, and with higher quality. CBSE offers potential advantages for performance engineering. If most of a new system consists of existing software components, it should be possible to predict properties like performance more easily, than if all of the software is ne...
