In this paper, a method based on Bayes theory is presented aiming at the problems of small sample maintainability verification for the shrapnel emitter. And Posterior Probability Ratio Test of maintainability index verification in the logarithmic normal distribution is discussed in detail. By analyzing the test data of the shrapnel emitter, it is proved that the method is effective and reasonable...
Several test strategies have emerged to detect faults associated Boolean expressions. Current approaches lack a proper model to give an overall picture of the Boolean expressions and comprehensive exploration of test data space. This paper proposes a topological model (T-model) to systematically represent Boolean expressions and test data space, and theoretically analyzes the capability and limitations...
Inclusion body refolding processes play a major role in the production of recombinant proteins. Improvement of the size-exclusion chromatography refolding process was achieved by combining a decreasing urea gradient with an increasing arginine gradient (two gradients) for the refolding of NTA protein (a new thrombolytic agent) in this paper. Different refolding methods and different operating conditions...
