An Improved WAGNER-WHITIN Algorithm

We present an improved implementation of the Wagner-Whitin algorithm for economic lot-sizing problems based on the planning-horizon theorem and the Economic- Part-Period concept. The proposed method of this paper reduces the burden of the computations significantly in two different cases. We first assume there is no backlogging and inventory holding and set-up costs are fixed. The second model ...

An Approach for Accurate Edging using Dynamic Membership Functions

In this paper, by means of fuzzy approaches, an accurate method is introduced for edging of color photographs. The difference between our method with other similar methods is the use of a morphological operation to think or thick the obtained edges. In this proposed method, a 3×3 window is dragged on the photo. For each block, 12 point sets will be defined, each including two non-overlapping po...

Improved stability of thin-film resistors

Earlier, deeper investigations into the drift behavior of thin-film resistors have shown that the usual methods for predicting drift are incapable of describing the present remarkable differences within a certain R-layer alloy system (for example, CrNi) or those between different alloy systems (for example, CrNi versus CrSi or TaN). In order to come to a more precise model, we have to ignore al...

An Accurate Correlation to Estimate Saturated Molar Volume of Liquids

There are a number of techniques available to estimate saturated-liquid molar or specific volumes or densities of liquids. In this study, a new empirical correlation is presented to calculate volume of saturated liquids as a function of critical volume, reduced temperature and acentric factor. An optimization algorithm is utilized to obtain unknown parameters of this correlation by fitting them...
