Estimation of collapse performance is primarily conducted through Collapse Fragility Curves (CFC’s). The EDP-based approach is the main scheme for attaining such curves and employs IDA. Obtaining CFC’s from IDA results is tremendously time consuming and computationally demanding. Introduction of more efficient methods of seismic analysis, can potentially improve this issue. The Endurance Time (...

Multilevel PWM waveforms can be decomposed into several multilevel PWM components. Phase-shifted carrier (PSC) is an efficient decomposition technique. In this paper, we have first demonstrated the equality of PSC and alternative phase opposition disposition techniques. Second, we have modified PSC to accommodate other disposition techniques. Third, we have investigated the effects of using...

Multilevel Inverters has big placement advantages in Power Electronics and its application can be mentioned to FACTS tools such as UPFC – D-STATCOM. Therefore, nowadays Multilevel Inverters have created vast field’s research and researchers are trying to present appropriate structures with fewer keys and greater advantages. The main advantages of Multilevel Inverters mentioned are low-key volta...

This paper aims at developing a multilevel fuzzy decision support model for urban rail transit planning schemes in China under the background that China is presently experiencing an unprecedented construction of urban rail transit. In this study, an appropriate model using multilevel fuzzy comprehensive evaluation method is developed. In the decision process, the followings are considered as th...

Amsterdam Conference on Multilevel Analysis: On April 1-2, 1997, an international conference about multilevel analysis was held in Amsterdam. The program was organised by Tom Snijders (ICS, University of Groningen; Multilevel research Group, NOSMO). This conference was one of the Social Science Information Technology workshops of ProGAMMA. There were about 60 participants from 10 countries. The...

OBJECTIVE Large health care datasets normally have a hierarchical structure, in terms of levels, as the data have been obtained from different practices, hospitals, or regions. Multilevel regression is the technique commonly used to deal with such multilevel data. However, for the statistical analysis of interactions between entities from a domain, multilevel regression yields little to no insi...

the purpose of this paper is to reconsider the theoretical basis and paradigms of policy making and economic policies in iran which is not appropriate to economic problems of the country. to do so, we introduced the multilevel and ultra-paradigm pattern for economic policy making in the country. the multilevel and interdisciplinary approach have been proposed as a solution for reforming the eco...

Multilevel analysis has recently emerged as a useful analytical technique in several fields, including public health and epidemiology. This glossary defines key concepts and terms used in multilevel analysis.

The implementation and analysis strategies plays vital role to minimize THD in Multilevel inverter. The modulation technique regards Selective harmonic Elimination and Space Vector Pulse Width Modulation(SVPWM).Multilevel inverters has tremendous application in the area of high-power and mediumvoltage energy control. In this paper simulation of SVPWM is performed for cascaded H bridge Multileve...

objective: regardless of three decades of implementation of family planning program in nepal, need of family planning services is largely unmet. systematic studies, evaluating the impact of family program on several ethnic groups of nepal has not been carried out in large scale. this study sheds light on the investigation of, whether the use of contraceptives varies among different ethnic group...
