We discuss the almost-sure convergence of a broad class of sampling algorithms for multi-stage stochastic linear programs. We provide a convergence proof based on the finiteness of the set of distinct cut coefficients. This differs from existing published proofs in that it does not require a restrictive assumption.
a survey-descriptive research methodology conducted 839 dehyaries, consisted the statistical population of the study. a number of 149 dehyaries were selected as sample using a multi-stage sampling technique. the questionnaire was approved to be both valid and reliable. to identify factors affect success of dehyaries, discriminate analysis was applied. the results revealed that organizational co...
dispersion and separated of agricultural lands are considered as the serious barriers of agriculture development. the smallest and distributed oflands are obstacle in the efficient use of water, land, labor, mechanization and other factors in agriculture production. the main purpose of this article is analyse the influenced factors of the rejection of land integration. the statistical populatio...
Conventional data envelopment analysis (DEA) models are used to measure efficiency score of production systems when they are considered as black boxes and their internal relationship is ignored. This paper deals with a common special case of network systems which is called multi-stage production system and can be generalized to many organizations. A multi stage production system has some stages...
هدف: این مطالعه به منظور بررسی ارتباط میان علائم بیماران و stage کارسینوم معده در بیماران مراجعه کننده به بیمارستان امیرالمومنین تهران طی سالهای 90-89 انجام شده است. روش مطالعه: در این مطالعه مقطعی، 30 فرد مبتلا به سرطان معده بررسی شدند که افراد از نظر staging بررسی شده و stage آنها ثبت گردید و در نهایت فراوانی علائم بالینی مختلف در stageهای مختلف مورد مقایسه قرار گرفت. یافته ها: 7/6 درصد در ...

Let sk = 1 √ N (v1k, . . . , vNk) T , with {vik, i, k = 1, . . .} independent and identically distributed complex random variables. Write Sk = (s1, . . . , sk−1, sk+1, . . . , sK), Pk = diag(p1, . . . , pk−1, pk+1, . . . , pK), Rk = (SkPkS ∗ k + σ 2 I) and Akm = [sk,Rksk, . . . ,R m−1 k sk]. Define βkm = pks ∗ kAkm(A ∗ km ×RkAkm) −1 A ∗ kmsk, referred to as the signalto-interference ratio (SIR)...
A linear calibration technique for on-line digital correction of analog imprecisions in the implementation of multi-stage analog-todigital converters, is presented. The calibration is ‘blind’, in that it uses no reference and operates directly on the digital output during conversion. The only assumption made on the input signal is that its spectrum is bandlimited. The excess sampling over Nyqui...
The article presents a mathematical model of multi-stage game the process safe control transport object in possible collision situations with other encountered objects, containing description state variables, and constraints, sets permissible strategies. Multi-criteria optimization tasks were formulated form positional matrix games under conditions playing non-cooperative cooperative as well no...
