The problem of obtaining the optimum design, which is able to discriminate between several rival models has been considered in this paper. We give an optimality-criterion, using a Bayesian approach. This is an extension of the Bayesian KL-optimality to more than two models. A modification is made to deal with nested models. The proposed Bayesian optimality criterion is a weighted average, where...

This paper presents contractors’ assessment and selection based on the multi-attribute methods in a competitive and risky environment. The model is based on a multi-attributes evaluation of contractors, the determination of their optimality criterion values calculated according to Hodges-Lehman rule. The proposed model could further be applied to construction operations. The attributes of contr...

In this paper, we propose a class of new threshold secret sharing schemes with repairing function between shares. Specifically, each share, when it is broken or lost, can be repaired by some others without the help of the dealer. Further, a construction of such repairable threshold secret sharing schemes is designed by applying linearized polynomials and regenerating codes in distributed storag...

OBJECTIVE To compare midwifery and medical care practices and measure optimal perinatal outcomes using a new clinimetric instrument. DESIGN Prospective descriptive cohort design. SETTING A large, inner city obstetric service with medical and midwifery services. PARTICIPANTS Three hundred seventy-five of 400 consecutively enrolled patients were participated (25 excluded due to extreme risk...

Sequential optimality conditions provide adequate theoretical tools to justify stopping criteria for nonlinear programming solvers. Here, nonsmooth approximate gradient projection and complementary approximate Karush-Kuhn-Tucker conditions are presented. These sequential optimality conditions are satisfied by local minimizers of optimization problems independently of the fulfillment of constrai...

diabetes mellitus is a common metabolic disease. its association with low level of testosterone is controversial. this study aimed to investigate the association between serum total testosterone, free testosterone index (fti), and sex hormone-binding globulin (shbg) in iranian men with type 2 diabetic.a case-control study was conducted on 38 non-diabetic and 36 diabetic men aged 40-60 years old...

environmental pollution consists of different types of pollutants in air, soil, and water. due to the fact that plants can respond to environmental pollution, they can be used as bio-indicators for environmental monitoring. air pollution in areas with oil and gas refineries nearby is an important problem. this study aims to survey the effects of gas refinery air pollutants on conocarpus erectus...

using productivity index for investigating a firms’ performance makes it possible to evaluate efficiency of the production system and cost at the same time. in this study the total factor productivity (tfp) of several sugar cane varieties in imam khomeini cultivation and processing center in khuzestan province is compared. two hundred and forty eight farms are categorized on the basis of variet...
