This paper deals with economic ordering policies for deteriorating items with inflation dependent demand rate under permissible delay in payments by considering selling price is necessarily higher than purchasing cost. We obtain optimal cycle time and we show the total cost function is concave for both cases i.e. case I and case II. We then develop an algorithm for a retailer to determine its o...

The present study calculates the Water Quality Index (W.Q.I.) of Pariyej Lake and assesses the impact of industries, agriculture and human activities. Physico – chemical parameters were monitored for the calculation of W.Q.I. for the rainy, winter and summer seasons. The parameters namely PH, Total hardness, TDS, Calcium, Chloride, Nitrate, Sulphate, DO and BOD values were within the permissibl...

Close-form representations for the permissible sampling rates on the first-order sampling of two-band bandpass signals are presented in this paper. It is shown that the new sampling rates are much lower than the Nyquist rate for signals with scattered passbands. A fast algorithm is developed for the symbolic operations on intervals, which makes the proposed sampling scheme more applicable. Key-...

In [2], the authors give a polynomial-time algorithm for deciding for a Boolean dynamical system in which each regulatory function is a monomial whether every limit cycle is a steady state. We show that the corresponding problem is NP-hard if the class of permissible regulatory functions contains the quadratic monotone functions xi ∨ xj and xi∧xj. We also show that the problem is NP-hard if the...

Introduction Due to increased awareness of the toxicity of organic substances, government organization, such as the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH), have continually decreased the permissible exposure limits of many organic substances. For example, in the last ten years, the permissible exposure limit for...
