breast cancer is the leading cause of malignancy among women. screening using mammography is proposed as an effective intervention for reducing early deaths due to breast cancer. we conducted a systematic review to assess the cost-effectiveness of such screening programs. we searched medline, scopus and google scholar and complemented it by other searches using sensitive search terms from 1993-...

Today’s wireless communication products become more complex and more integrated. The low cost prices paid by the consumer for wireless phones and the competitive market imposed a tremendous pressure to have low cost RF ICs. The test cost becomes almost the main factor determining profit margin. To economically test high volumes of integrated RF ICs at a fraction of the cost of the IC we have to...

Uncertain switched linear systems are known as an important class of control systems. Performance of these systems is affected by uncertainties and its stabilization is a main concern of recent studies. Existing work on stabilization of these systems only provides asymptotical stabilization via designing switching strategy and state-feedback controller. In this paper, a new switching strate...

The rapid progress in the competitive business environment has increased customer expectations and demands, thus leading to a situation where many companies are competing fiercely, especially low-cost airline or carriers (LCCs). company carries out strategy of providing satisfaction for its passengers generate great loyalty. purpose this study is find what factors can affect passenger loyalty, ...

We propose a simple model to compute the probability of success under a quorum sensing strategy. We show that a quorum sensing strategy has a higher probability of success than an individualistic strategy when, for instance, the probability of success for a single individual is low and the cost of building a quorum is not too high. On the other hand if the cost of building a quorum is too high ...

Shaft position sensing is an essential part of switched reluctance (SR) motor drive In order to synchronize the pulses of phase current with the period of rising inductance of the proper motor phase. Direct sensors such as, Hall effect and optical encoder are commonly used in SR motors. The purpose of this paper is to present an indirect shaft positioning sensing known as "sensorless " control ...
