hiv epidemic in iran is in the focused stage and still less than 70 thousand hiv positive people are recognized. given that there are more than 2000 private and governmental addiction treatment centers in iran covering more than half a million patients, there is a great potential for these centers to recognize hiv positive cases of iran, in case of précised planning. current article tried to ev...

manufacturers need to evaluate the reliability of their products in order to increase the customer satisfaction. proper analysis of reliability also requires an effective study of the failure process of a product, especially its failure time. so, the failure process modeling (fpm) plays a key role in the reliability analysis of the system that has been less focused on. this paper introduces a f...

Taking a memory test not only assesses what one knows, but also enhances later retention, a phenomenon known as the testing effect. We studied this effect with educationally relevant materials and investigated whether testing facilitates learning only because tests offer an opportunity to restudy material. In two experiments, students studied prose passages and took one or three immediate free-...

Creating functional tests that work on an ATE has always been a significant challenge [1]. This paper identifies the fundamental mechanisms for functional test failures of an SOC on an ATE. Taking these mechanisms into account during the design process of a chip can substantially reduce the efforts needed to make functional tests work. We call this process design for functional testability (DFFT).
