the problem of designing a set of routes with minimum cost to serve a collection of customers with a fleet of vehicles is a fundamental challenge when the number of customers to be dropped or picked up is not known during the planning horizon. the purpose of this paper is to develop a vehicle routing problem (vrp) model that addresses stochastic simultaneous pickup and delivery in the urban pub...

a partial least squares (pls) calibration model was developed for the simultaneous spectrophotometricdetermination of pb (ιι), cu (ιι) and ni (ιι) using xylenol orange as a chromogenic reagent. the parameterscontrolling behavior of the system were investigated and optimum conditions were selected. the calibrationgraphs were linear in the ranges of 0.0–9.091, 0.0–2.719 and 0.0–2.381 ppm for lead...

a simple, accurate and precise hptlc- densitometry method for the simultaneousdetermination of abacavir, lamivudine and zidovudine in pharmaceutical tablet has beendeveloped. separation of tablet components was performed on aluminum backed hptlc plates(silica gel 60 f254 20×20 cm with 0.2 mm thickness, camag, muttenz, switzerland ) usingmethanol : chloroform : acetonitrile (4 : 8 : 3 v/v). good...

Background & Aims of the Study:  Corrosion and scaling are the most common problems of water facilities. Corrosion imposes many financial and health loss on system and consumer respectively, scaling also causes clogging and head loss in network. The purpose of this study is to determine the corrosion and scaling potential of water supply sources of Qom villages. Materials &...

Sparse support vector machine (SVM) is a popular classification technique that can simultaneously learn a small set of the most interpretable features and identify the support vectors. It has achieved great successes in many real-world applications. However, for large-scale problems involving a huge number of samples and extremely high-dimensional features, solving sparse SVMs remains challengi...
