In this study, we considered an inflationary inventory control model under non-deterministic conditions. We assumed the inflation rate as a normal distribution, with any arbitrary probability density function (pdf). The objective function was to minimize the total discount cost of the inventory system. We used two methods to solve this problem. One was the classic numerical approach which turne...

In any problem involving images having scale-dependent structures, a key issue is the modeling of these multi-scale characteristics. Because multi-scale phenomena frequently possess nonstationary, piece-wise multi-model behaviour, the classic hidden Markov method can not perform well in modeling such complex images. In this paper we provide a new modeling approach to extend previous hierarchica...

eyf served as a control. Intraperitoneal [Ii ]-thyeidine was injected. Three eyes were studied histologically and autoradiographically at 1 hr, 3 hr. 6 hr. 9 hr, 12 hr, 24 hr, 2 d, 3 d, 9 d, 12 d, 15 d, 18 d and 21 d. The epithelial cells were scanned from limbus to limbus. Analysis of variance and linear regression (SPSS package) were used for statistical evaluation. Results: The cells prolife...

For the applied economist, the confident and apparently successful application of Keynesian principles to economic policy which occurred in the United States in the 1960s was an event of incomparable significance and satisfaction. These principles led to a set of simple, quantitative relationships between fiscal policy and economic activity generally, the basic logic of which could be (and was)...

High prevalence of human herpesvirus type 8 (HHV-8) infection has been reported on the island of Sardinia. Among emigrants from Sardinia, rates of HHV-8 infection are lower than they are in Sardinia and are similar to those observed in the local population. Thus, environmental factors seem to play a relevant role in affecting the prevalence of HHV-8 infection.
