Sampling, sample recovery, laboratory preparation and analysis and performing calculations all introduce errors into a final test result. Even without any mistakes, random errors will remain. The precision of a method -the size of likely random errors from all sources from sampling tech­ niques through data reduction -is determined by analyzing the differences between simultaneous measurements....

This paper designs a mathematical model for supply chain network design problem including plants, distributors and customers in fuzzy environment. Each plant and distributor has several levels capacities. A multi-mode demand strategy is considered for the customers where only one of the modes is to be selected for each customer. Considering the acceptance degree of fuzzy constraints violated, a...

In this paper‎, ‎the aim is to find a complex interval vector [Z] such that satisfies the complex interval linear system C[Z]=[W]‎. ‎For this‎, ‎we present a new method by restricting the general solution set via applying some parameters‎. ‎The numerical examples are given to show ability and reliability of the proposed method.

This study compared the acute effect of strength, plyometric, and complex exercises (combined strength and plyometric exercise) in the countermovement jump (CMJ) and frequency speed of kick test (FSKT) and attempted to establish the best rest interval to maximize performance in the CMJ, number of kicks, and impact generated during FSKT. Eleven taekwondo athletes (mean ± SD; age: 20.3 ± 5.2 year...

type2 diabetic is a metabolic disease in which is associated with the relative or absolute insulin deficiency, elevated blood glucose and impaired metabolism of carbohydrates, fat and protein. since fat and exercise is important to improve glycemic control in diabetic patients, so the purpose of this study was to evaluate the effect of interval training on a cycle ergometer on insulin resistanc...

The aim of this paper is to present the interval zoro symmetric singlestep procedure IZSS1 which is the modification of interval symmetric single-step procedure ISS1. This procedure has a faster convergence rate than does ISS1. We start with suitably chosen initial disjoint intervals where each interval contains a zero of a polynomial. The IZSS1 method will produce successively smaller interval...
