in this research, a new control policy for the acceptance sampling problem is introduced. decision is made based on the number of defectives items in an inspected batch. the objective of the model is to find a constant control level that minimizes the total costs, including the cost of rejecting the batch, the cost of inspection and the cost of defective items. the optimization is performed by ...

Mrs. Horace Darwin (later Lady Darwin) conducted an inquiry into lhe number of feeble-minded children ?f school age in Cambridge. This showed th...

In this paper we study a new, generalized version of the wellknown group testing problem. In the classical model of group testing we are given n objects, some of which are considered to be defective. We can test certain subsets of the objects whether they contain at least one defective element. The goal is usually to find all defectives using as few tests as possible. In our model the presence ...

MEPROBAMATE is the shortened name of 2-Methyl-2-n-Propyl-l,3 propanediol dicarbamate, which is also known as Miltown or Equanil. Previously published reports (1—5)on clinical trials of this drug have concerned its effect on patients suffering from neurotic and psychotic disorders. As far as we are aware no reports have been published of its effects on mentally defective patients. The clinical...

In this paper, we present a model and an algorithm for the calculation of the optimal control limit, average cost, sample size, and the sampling interval for an optimal Bayesian chart to control the proportion of defective items produced using a semi-Markov decision process approach. Traditional p-chart has been widely used for controlling the proportion of defectives in various kinds of produc...

Introduction Reports of Norwegian or crusted scabies occurring in England are rare (Calnan, 1950). In this condition itching is not a constant symptom, burrows may not be present and the acarus may be found on the head and neck. The acarus is seen within scales and the gross hyperkeratosis may give the skin the appearance of the bark of a tree. Norwegian scabies has been reported in mental defe...

as the outdoor activities of mental defectives in institutions had previously been limited to elementary jobs, such as sweeping the paths, and generally acting as labourers to the staff engaged on the ornamental gardens. It was recognised that, for many years, patients in large mental institutions and colonies had been employed on farms, pig feeding, etc.; some of them had been taught to milk c...
