Column-by-column compositional mapping by Z-contrast imaging
Ultramicroscopy, 2009A phenomenological method is developed to determine the composition of materials, with atomic column resolution, by analysis of integrated intensities of aberration-corrected Z-contrast scanning transmission electron microscopy images. The method is exemplified for InAs(x)P(1-x) alloys using epitaxial thin films with calibrated compositions as ...

Composite Connections to External Columns
Journal of the Structural Division, 1976The behavior of beam-to-column connections in composite rigid frames is examined and the results of tests on ten specimens are presented. The steel beams are connected to concrete slabs by welded studs and are subjected to negative moment. The columns are of encased I-section bent about the major axis.

Beams, Columns and Rods of Composite Materials
1987A beam, column or rod is a long thin structural component of width b, height h and length L, where b/L ≪ and h/L ≪ 1, as shown in Figure 4 ...

Column-by-column compositional imaging by z-contrast STEM
Proceedings, annual meeting, Electron Microscopy Society of America, 1992The use of a high-angle detector in STEM imparts incoherent characteristics to the image while simultaneously introducing a strong compositional sensitivity through the ∼Z2dependence of the highangle scattering cross sections. The destruction of coherence is achieved in two ways.

Buckling of stepped composite columns
Mechanics of Composite Materials, 2006The stability of elastic columns subjected to axial pressure is studied. An elastic multistepped column with rectangular cross sections are considered assuming that at the re-entrant corners of the column stable cracks are located. The influence of a crack on the loss of stability of the column is described by means of local flexibility and the ...

In previous chapters we have discussed big data problems, Cassandra data modeling concepts, and various schema management techniques. Although you should avoid normalizing the form of your data too much, you still need to model read requirements around columns rather than primary keys in your database applications.

Bending of a composite beam-column
Archive of Applied Mechanics, 1991The paper deals with the bending of a composite beam-column of variable cross-section. The governing equation is developed under usual assumptions concerning the beam-column deformation (the deformation is not small enough to neglect its effect on the equilibrium equations, but it is sufficiently small for geometrical linearization to be carried out ...

Steel-Concrete Composite Columns
Transportation Research Record: Journal of the Transportation Research Board, 1997Structural steel shapes and tubes can be used with concrete to produce structural components. The performance of such composite systems, is better than the sum of responses of the parts taken separately. In a concrete-filled steel tube caisson, for example, the steel casing resists flexural tension efficiently while confining the concrete core as the ...

Elastic Stability of Composite Column
Journal of Engineering Mechanics, 1992A vertical column possessing two different flexural rigidities is clamped at the bottom end and is free at the top. Both piecewise uniformly distributed axial loads (self-weights) and a concentrated load at the top are applied to the column. For the buckling load, the governing differential equation is a second-order nonlinear with variable ...
