What is the connection between the UNCITRAL model for electronic commerce laws and the U.S. 2000 presidential election imbroglio? How does this connection, if recognized, resonates certain milestones of our civilization's heritage, legacies from the Phoenicians and from the Roman empire? There is something basic about human communication and reasoning which weaves through these themes, in the w...

Before three dimensional numerical test of four connection systems in chapter 4, the author would like to compare the experiemental test results and numerical methods. The reasons for this comparison are to check the reliability of Finite Element‘s procedures for the interaction between the node connector and beam element and to implement numerical analysis of moment-rotation behavior taking ge...

In this paper, we explore a connection between binary hierarchical models, convex geometry, and coding theory. Using the so called moment map, each hierarchical model is mapped to a convex polytope, the marginal polytope. We realize the marginal polytopes as 0/1-polytopes and show that their vertices form a linear code. We determine a class of linear codes that is realizable by hierarchical mod...

It has been argued recently that mirror symmetry exchanges two pure spinors characterizing a generic manifold with SU(3)-structure. We show how pure spinors are modified in the presence of topological D-branes, so that they are still exchanged by mirror symmetry. This exchange emerges from the fact that the modified pure spinors come out as moment maps for the symmetries of A and B-models. The ...

the electric quadrupole, hexadecapole moments, energy (kjmol -1) for some armchair polyhex carbon nanotubes tuvc6[2p,q] are performed by beck-lee-yang-parr [b3lyp] on 3-21g basis set using the standard procedure indices gaussian 98, then the padmakar-ivan (pi) index of tuvc6[2p,q] nanotubes in the terms of their circumference (2p) and lengh (q) is calculated and the relationships between the pa...

Intelligent tutors have become increasingly accurate at detecting whether a student knows a skill, or knowledge component (KC), at a given time. However, current student models do not tell us exactly at which point a KC is learned. In this paper, we present a machine-learned model that assesses the probability that a student learned a KC at a specific problem step (instead of at the next or pre...

statistical frequency analysis is the most common procedure for the analysis of flood data at a gauged location thatin first step it is needed to select a model to represent the population. among them, the central moment has been themost common and widely used, and with the using of computers, the application of the maximum likelihood hasincreased. this research was carried out in order to reco...

The connections are used to transfer forces and moments due applied loading. capability of the connection in resisting moment is classify types steelwork particularly for cold-formed steel. Classification schemes based on total moment-rotation behavior have been developed aid design analysis connections. Moment-rotation curve commonly describe that can be obtained from either theoretical or exp...

Shear reinforcement is one of the common measures used to strengthen slab–column connections. It can make joint’s load capacity increase. However, when connection subjected an unbalanced bending moment, reduction effect shear on moment worth investigating. Nonlinear finite element analysis was performed reinforced concrete slabs with for various moment-to-shear (M/V) ratios. The effects number ...
