A new method is proposed in this paper for multiple fault diagnosis in linear analog circuits. The test equation in the traditional large change sensitivity method is modified to establish the linear relationship between the measurements and the faulty parameter deviations with the coefficient matrix derived from the nominal values of circuit parameters. By using a recently developed method to ...

As the component parameters of analog circuits are influenced by tolerance, a soft fault-concept diagnosis model in this paper, which is based on the qualitative concepts of cloud model theory, is proposed to achieve the complete description of fault states and the fast diagnosis. The diagnosis model uses the cloud transform method to represent the conceptual soft classification of the multiple...

gonadotropin releasing hormone (gnrh) plays a key role in reproduction. this decapeptide is synthesized and released by hypothalamus and induces the pituitary gonadotrop cells to release pituitary gonadotropin hormones. in some extrapituitary compartments gnrh and its receptor act as part of the autocrine regulatory system of cell proliferation. the anticancer activity of gnrh and its analogues...

driver fatigue is one of the main causes of road accidents. this study aimed to estimate bus driver fatigue through performance measures in a virtual driving environment. the study was conducted on thirty professional male bus drivers participated in a two-hour drive session. the driver subjective fatigue was assessed by fatigue visual analogue scale (f-vas) on 10 min intervals. at the same tim...

a b s t r a c tintroduction: although decision-making processes have become a principal target of study among addiction researchers, few researches are published according to effects of different treatment methods on the cognitive processes underlying decision making up to now. utilizing cognitive modeling method, in this paper we examine the effects of methadone maintenance treatment (mmt) on ...

D igital computers and mammalian brains share not only a talent for computation but also a method that favors absolutes. The ones and zeros of a computer are analogous to the all-or-none character of action potentials in the brain. Neurons sum all incoming depolarizing signals until, at a threshold level of depolarization, an action potential fi res along the axon. Now, however, Henrik Alle and...
