A modified Cholesky factorization algorithm introduced originally by Gill and Murray and refined by Gill, Murray and Wright, is used extensively in optimization algorithms. Since its introduction in 1990, a different modified Cholesky factorization of Schnabel and Eskow has also gained widespread usage. Compared with the Gill-Murray-Wright algorithm, the Schnabel-Eskow algorithm has a smaller a...

Background: Brucellosis is one of the important zoonotic diseases with variety of symptoms and signs. Using of cost effective, easy and safe diagnostic methods in screening of brucellosis is an important priority. Several studies have been carried out to recognize appropriate diagnostic methods and each have reported different results. Aim: The aim of this study was to investigate the sensitivi...

This paper presents a marching method for computing intersection curves between two solids represented by subdivision surfaces of Catmull-Clark or Loop type. It can be used in trimming and boolean operations for subdivision surfaces. The main idea is to apply a marching method with geometric interpretation to trace the intersection curves. We first determine all intersecting regions, then find ...

in the process of this research Problems that occur is an irregular delivery goods takes a lot time and distance, so distribution not optimal. Therefore, researchers will conduct on how to determine best route optimizing distance time. The purpose study find routes are more optimal by using nearest neighbor Clarke Wright savings do comparison with company's current This. mileage 319.9 km while ...

Bicarbonate anion, has a very high concentration in the calcareous soil, and in fact, is the main cause of chlorosis in calcareous soils. This study was conducted to evaluate eight soybean cultivars with iron deficiency and bicarbonate presence. The present research was carried out with the aim of assessing the effect of irrigation with water containing bicarbonate on enzyme activities and Fe a...
