In this paper, a new cascaded multilevel inverter by capability of increasing the number of output voltage levels with reduced number of power switches is proposed. The proposed topology consists of series connection of a number of proposed basic multilevel units. In order to generate all voltage levels at the output, five different algorithms are proposed to determine the magnitude of DC volta...

There is a persistent shortage of underrepresented minority (URM) faculty who are involved in basic biomedical research at medical schools. We examined the entire training pathway of potential candidates to identify the points of greatest loss. Using a range of recent national data sources, including the National Science Foundation's Survey of Earned Doctorates and Survey of Doctoral Recipients...

The selection and implantation of sufficient and appropriate continuous improvement strategy are the key success factors for improving firm performance and enhancement of competitive advantage on manufacturing industries. As a result special role are given to Continuous improvement programs such as Supply Chain Management (SCM), Six-Sigma, Total Quality Management (TQM), Kaizen, Just-in-Time (J...

to present the basic principles and standards of ethics in medical research and publishing, as well as the need for continuing education in the principles and ethics in science and publication in biomedicine. an analysis of relevant materials and documents, sources from the published literature. investing in education of researches and potential researches, already in the level of medical schoo...

The detection of hazardous radiation sources is difficult for several reasons. Sensors detect when photons, generated randomly by sources, strike crystals and so sensors don’t get continuous information streams. Radiation emanates from threats but also from walls, the ground and medical patients undergoing radiation treatment. There may be multiple, mobile, evasive sources. The number of parame...

An ETL process includes various ETL activities, such as filtering, aggregating, checking for null values, etc., which can be represented by the constraint functions and transforming operations defined in previous section. However, the activities cannot exist in an ETL process independently; they must be organized in certain order that is specified in an ETL task of the ETL process. We think tha...
