در این پژوهش سعی می‌­شود مدلی برای شبیه‌­سازی چرخه عمر صنعت برق با استفاده از شبیه‌سازی عامل­بنیان ارائه شود، مدل، 5 عامل استخراج شد و شبیه­‌سازی به کمک نرم‌افزار Anylogic صورت پذیرفت. بهینه‌­سازی مدل چهار سناریو نظر خبرگان شد. سناریوی نخست، جذابیت نیروگاه گازی سیکل ترکیبی کاهش یافت بر دو دیگر افزوده نتیجه افزایش تولید آبی است که توجه کمبود منابع کشور به‌صرفه نیست. دوم ورود یک فناوری جدید میزان...

An indeterminate string (or, more simply, just a string) x = x[1..n] on an alphabet Σ is a sequence of nonempty subsets of Σ. We say that x[i1] and x[i2] match (written x[i1] ≈ x[i2]) if and only if x[i1]∩x[i2] 6= ∅. A feasible array is an array y = y[1..n] of integers such that y[1] = n and for every i ∈ 2..n, y[i] ∈ 0..n−i+1. A prefix table of a string x is an array π = π[1..n] of integers su...

This study provides basic descriptive data on the frequency of pairwise eruption sequences ascertained in cross-sectional examination of 6,000 black and white American children in the Ten State Nutritional Survey of 1968-1970. All sex and race groups share a distinct pattern of sequence polymorphisms in terms of location, number, and level. Teeth in eruption phase I (M1, I1, I2) rarely reverse ...

BACKGROUND Rotavirus viral protein 6 (VP6), encoded by genome segment (GS) 6, is the primary target for rotavirus diagnosis by serological and some molecular techniques. Selected full length nucleotide sequences of GS 6 of rotavirus strains from South Africa were sequenced and analysed to determine genetic diversity and variations within the circulating rotaviruses. FINDINGS The VP6 amplicons...

A field experiment was conducted to study the effect of deficit irrigation and mulch levels on soil physical properties and growth and yield of maize crop. The experiment comprised of two irrigation levels, i.e. I1: 558.8 mm and I2: 711.2 mm while two mulch levels, i.e. M0: no mulch and M15: 15 Mg ha. Soil samples were collected from 0-10, 10-20, and 20-30 cm depths before sowing and at crop ha...

mold powders used in the continuous casting of steel contain the harmful caf2 as a main substance developing toxic gases such as sif4 and hf at elevated temperatures. in this study, three samples of i1, i2 and i3, which contained gypsum free portland cement clinker with different percentages of fe2o3 (5.68, 6.83, 8.02 ) and f- (2.09, 1.06, 0), were prepared and their main characteristics were c...

A class of knapsack problems which generalizes the classical ones is studied. Algorithms based on the dynamical programming and Branch and Bound methods are proposed. The correctness and time estimation of the algorithm are given. 1 Problem formulation We study a class of knapsack problems which generalizes problems from [1-2]. The main mathematical model we shall use is formulated as follows. ...

The enzyme UGT2B7 is one of the most active UDP-glucuronosyltransferases (UGTs) involved in drug metabolism and in maintaining homeostasis of endogenous compounds. We recently reported the existence of 22 UGT2B7 mRNAs, two with a classic 59 region but alternative 39 ends namely UGT2B7_v5 (containing a novel terminal exon 6b) and _v7 (exon 5 excluded) that encode enzymatically inactive isoforms ...

We discuss the aysmptotics of the points that maximize the determinant of the interpolation matrix for interpolants of the form I1(x) = n ∑ i=1 aie αxti and I2(x) = n ∑
