We present a small, compact and portable device for point-of-care instantaneous early detection of anemia. The method used is based on direct hematocrit measurement from whole blood samples by means of impedance analysis. This device consists of a custom electronic instrumentation and a plug-and-play disposable sensor. The designed electronics rely on straightforward standards for low power con...

We analyse the cost performance of LAN interconnection over ATM using switched VC. Frame loss due to buuer overrow during connection setup has been taken into consideration in the proposed cost function. We investigate the eeect of the length of the holding time of an idle VC on the total cost per frame transmitted. Our simulation results suggest that there is no optimum holding time for minimi...

and Applied Analysis 3 CS(D i , x i ): total costs including shortage costs and storage costs for item i P(D i , x i ): profit for item i. For the ith item, some assumptions are introduced as follows. (i) The time horizon is infinite. (ii) The production rate is instantaneous. (iii) The lead time is zero. (iv) There is no fixed ordering cost and there is no initial inventory. (v) The demandD i ...

Developing public transportation and giving priority to buses is a feasible solution for improving the level of public transportation service, which facilitates congestion alleviation and prevention, and contributes to urban development and city sustainability. This paper presents a novel bus operation control strategy including both holding control and speed control to improve the level of ser...

in this paper, a production inventory model is developed for the business enterprise which consists of three wings. the first wing is for manufacturing new items, the second wing is for collecting the returned items, while third wing is for remanufacturing the returned item. in this model we consider the fact that the storage item is deteriorated during storage periods and salvage value is inco...

 This paper presents an inventory model with non-instantaneous receipt under the condition of permissible delay in payments. Certain items like volatiles deteriorate during production process. In this paper, we consider deterioration into two phases i.e. phase 1 and phase 2. The purpose of this paper is to determine the optimal replenishment policies under conditions of non-instantaneous recei...

Gray markets are unauthorized channels of distribution for a supplier’s authentic products. This paper studies a distribution channel that consists of a supplier who offers all-unit quantity discounts for batch orders to enjoy cost savings, and a reseller who may divert some goods to the gray markets. Our analysis shows the impact of gray markets depends on the reseller’s batch inventory holdin...
