Seismic isolation systems exposed to far-fault earthquakes can reduce floor accelerations and story drift ratios acceptable levels. However, they exhibit different structural performances in each earthquake due excitation frequency contents. By optimizing the system parameters, their performance may be maintained at best level under earthquakes. In this study, optimization of parameters nonline...

One goal of e-learning is to enhance the interoperability and reusability of learning resources. However, current elearning systems do little to adequately support this. In order to achieve this aim, the first step is to consider how to assist instructors in re-organizing the existing learning objects. However, when instructors are dealing with a large number of existing learning objects, manua...

This paper presents an algorithm for solving the multi-objective reactive power dispatch problem in a power system. Modal analysis of the system is used for static voltage stability assessment. Loss minimization and maximization of voltage stability margin are taken as the objectives. Generator terminal voltages, reactive power generation of the capacitor banks and tap changing transformer sett...
