This paper offers a reassessment of the socialist calculation debate, and examines the extent to which the conclusions of that debate must be modified in the light of the subsequent development of the theory and technology of computation. Following an introduction to the two main perspectives on the debate which have been offered to date, we examine the classic case mounted by von Mises against...
this study presents data on age structure, sex ratio, growth, length-weight relationships and condition factor of four populations (n=312) of two alburnoides species, collected in 2005 and 2006 from the tajan river (caspian sea basin), the ghara-chai and jajrud rivers (namak lake basin), and cheshmeh-ali spring (kavir basin) of iran. sex ratio of the fish, in the studied localities, except in ...
in the present work, the quantum theoretical calculations of the molecular structure of the 1-(1, 3-benzothiazol-2-yl)-3-(thiophene-5-carbonyl) thiourea has been predicted and are evaluated using density functional theory (dft) in gas phase. the geometry of the title compound was optimized by b3lyp/6-311+g and b3lyp/6-311+g* methods and the experimental geometrical parameters of the title compo...
هدف: برای به دست آوردن بیشترین فواید از جراحی stn-dbs، هدف باید به دقت معین شود. برای سالها، بهترین روش آناتومیک برای هدف¬یابی stn مورد چالش بوده است. هدف از این مطالعه، تعیین دقیقترین روش مکان¬یابی آناتومیک stn (هدف¬یابی on-screen mri مستقیم، در نماهای کرونال و اگزیال؛ هدف¬یابی کامپیوتری با نرم¬افزار در نماهای کرونال و اگزیال، هدف¬یابی بر اساس اطلس شالتربراند-وارن، و روش هدف-یابی ترکیبی) در مق...
In the previous paper, the basic concepts of sample size calculation were presented. This paper explores main post-calculation adjustments of the sample size calculation in special circumstances such as multiple group comparisons, unbalanced studies (with unequal number of subjects in different groups) sample size correction for missing data, and adjustment for finite population size. In additi...
