attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Introduction According to the most recent climate classification that has done yet, about 90 percent of Iran is located in arid and semi-arid climate and more than 40 percent of Iran is facing a severe water crisis. Therefore, understanding the behavioral mechanisms of dry spells has a great significance in arid and semi-arid area, like country of Iran. Especially with the pose of the ph...
The problem of the longest common subsequence is a classical distance measure for strings. There have been several attempts to accommodate longest common subsequences along with some other distance measures. There are a large number of different variants of the problem. In this paper, we consider the constrained longest common subsequence problem for two strings and arbitrary number of constrai...
Let X1, . . . , Xn and Y1, . . . , Yn be two independent sequences of i.i.d Bernoulli variables with parameter > 0. Let X designate the string X := X1X2 . . . Xn and let Y := Y1Y2 . . . Yn. Let Ln designate the length of the longest common subsequence (LCS) of X and Y . We prove that for a constant c > 0, VAR[Ln] > cn if > 0 is taken small enough. Hence for small , the order of magnitude of VAR...
در این پایان نامه، به کمک نرم افزار flow-3d میدان جریان عبوری از سریز اوجی بررسی می گردد. همچنین اثر هندسه سرریز و بلندای آب بالا دست سرریز بر میدان جریان و توزیع فشار بررسی شده و تاثیر مدل های مختلف آشفتگی (prandtl، و rng (renormalized group) در میدان جریان نیز مورد توجه بوده است. نرم افزار flow-3d یک برنامه تحلیلی میدان جریان است که معادلات حاکم بر میدان جریان عبوری از روی سرریز که همان معادل...
