The Moment-of-Fluid (MOF) method is a new volume-tracking method that accurately treats evolving material interfaces. The MOF method uses moment data, namely the material volume fraction, as well as the centroid, for a more accurate representation of the material configuration, interfaces and concomitant volume advection. In contrast, the Volume-of-Fluid (VOF) method uses only volume fraction d...

Assume that the potential q(r), r > 0, is known for r ≥ a > 0 and the phase shifts δl(k) are given at a fixed energy, i. e., at a fixed k > 0, for l = 0, 1, 2, . . .. The inverse scattering problem is: find q(r) on the interval 0 ≤ r ≤ a using the above data. The proposed numerical method consists of a reduction of this problem to a moment problem for q(r) on the interval r ∈ [0, a]. The moment...

The question of whether architectural creativity is more of an artistic or engineering nature is one with a long history but also one with no conclusive answer. The art camp would argue that technology should be treated as a means towards and end, and that technology alone cannot give meaning to our lives. The engineering camp on the other hand would argue that good problem-solving result...

Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...

Even if we disregard all those nominal expressions employed with purely connotative meaning, that is, those which do not refer to any object, and confine our attention to nouns which are names of things, it is clear that no extant lexicon contains anywhere near enough expressions of this kind to suffice even for ordinary daily life. We cannot get along with any single common noun to refer to a ...

In this paper, the plastic limit load of cylindrical shells with opening subject to combined bending moment and axial force are found by finite element method using ANSYS suite of program. The effect of various parameters such as the geometrical ratios of shell and the shape, size, axial and angular position of the opening on the limit load of cylindrical shells under various loading conditions...
