Jacketing of reinforced concrete columns is a common and useful strengthening method. This method substantially improves mechanical properties of the column, such as flexural strength as well as shear and ductility. In this paper, the behavior of confined reinforced concrete columns are investigated. The results indicate that the method is more effective for slender columns in the region of the...

The understanding of the dynamic behavior of distillation columns has received considerable attention due to the fact that distillation is one of the ost widely used unit operations in chemical process industries. Thermally coupled distillation sequences (TCDS) can provide significant energy avings with respect to the operation of sequences based on conventional distillation columns. TCDS exhib...

MOTIVATION It has recently become possible to build reliable de novo models of proteins if a multiple sequence alignment (MSA) of at least 1000 homologous sequences can be built. Methods of global statistical network analysis can explain the observed correlations between columns in the MSA by a small set of directly coupled pairs of columns. Strong couplings are indicative of residue-residue co...

In this study, the co-operation of steel and concrete in composite columns is considered. Using numerical modeling to study the behavior of these sections, a new type of sections, namely Concrete Filled Double-Skin steel Tubular (CFDST) columns, is introduced. The parameters and techniques that influence the numerical simulation that bring this modeling closer to...

Steel-reinforced concrete (SRC) columns, which are classified as composite columns, became the most widely used in recent years; because of their extensive advantages over the reinforced concrete and the steel columns. In this paper, the ductility index and its influential factors were explored to investigate the behavior of SRC columns. A straightforward approach was then proposed by establish...

Let μ = {μ1, μ2, . . . , μs} and ν = {ν1, ν2, . . . , νt} be two decreasing sequences of positive rational numbers of lengths s ≥ 1 and t ≥ 1, respectively i.e. μ and ν satisfy μ1 > μ2 > . . . > μs and ν1 > ν2 > . . . > νt. Let m = {m1,m2, . . . ,ms} and n = {n1, n2, . . . , nt} be two sequences of positive integers such that m = ∑s i=1mi and n = ∑t i=1 ni. The rows of B are indexed by x = (x1,...

In this work we use adjusted parameters obtained with Simulated Annealing and those from Dechema Collection [1] for the NRTL model, in order to analyze their effect in the design, optimization, and control of homogeneous azeotropic distillation columns. For the design of the azeotropic sequences we use short design methodologies [2, 3], while a multiobjective genetic algorithm with constraints ...

In this paper we study the design and optimization of heat-integrated distillation columns (HIDiC) using a constrained Boltzmann-based estimation of distribution algorithm. The total annual cost was defined as the fitness function of the problem, and the effect of the relative volatility on the performance of the HIDiC configurations was evaluated. We analyzed a set of equimolar mixtures with r...

The theoretical upper bound of generalization error for ECOC SVMs is derived based on Fat-Shattering dimensionality and covering number. The factors affecting the generalization performance of ECOC SVMs are analyzed. From the analysis, it is believed that in real classification tasks, the performance of ECOC depends on the performance of the classifiers corresponding to its coding columns, whic...
