In this research, the main parameters of the multivariate CUSUM control chart (the reference value k , the control limit H , the sample size n , and the sampling interval h ) are determined by minimizing the Lorenzen-Vance cost function (Lorenzen TJ, Vance LC. The economic design of control charts: A unified approach. Technometrics 28: 3-10, 1986 [1],) in which the external costs of employing t...
Along with the widespread use of Taguchi methods in product design, deenition of the loss function has been integrated with numerous models which require quality cost estimation. In this paper, the economic-statistical design of a variable sampling X-bar control chart is extended using the Taguchi loss function to improve chart eeectiveness from a quality cost point of view. The eeectiveness of...
the aim of this research is to compare two weight loss methods in 20 to 25- year-old well-trained wrestlers. 30 well-trained wrestlers participated in this research voluntarily and then were randomly divided into two groups. their percentage of body fat (measured with caliper) and strength and endurance of their upper and lower extremities were measured before and after the weight loss program....
in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
parameters as interception, infiltration, water storage on surface holes and soil profile, evapotranspiration are factors of loss water in a watershed and avoid from changing of precipitation to runoff. in this study, by use of hec-hms model and comparison of results of different methods of precipitation loss evaluation (initial and constant, green & ampt, scs curve number, deficit & constant a...
