Abstract: This paper presents the simplified method of random test suite based on the frequency (block) test. The test is used to check the first property of random numbers which is to have the same probabilities of being "1" and "0". Most college teachers assume that more tests are better than a few. Why? What caused us to decide on three or four unit tests followed by a final? Is there evidence that students don't do as well in courses where there are only a midterm and a final? Why do we think that more tests might be better? And what do we mean by. Using the most recently available national data, physicians with electronic health record (EHR) access ordered more tests than their non-EHR counterparts, thus contradicting a common rationale for EHR implementation. In this research, a complete system of a force control unit implemented on a home-built electro-mechanical fatigue test machine is proposed. The entire system includes an electro-mechanical shaker, a load cell, a controller, dedicated software, and an external metallic structure to constrain the specimen. Admittedly, the.
