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.

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 ...

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.

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 ...

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 ...

Slender Composite Beam‐Columns
Journal of Structural Engineering, 1988A method for performing inelastic stability analysis of composite beam‐columns under different load and end conditions is presented. Nondimensional expressions describing the moment‐thrustcurvature relations are derived and then used to formulate and solve the governing differential equations.

Column shortening of concrete cores and composite columns in a tall building
The Structural Design of Tall and Special Buildings, 2005The effect of column shortening is a major consideration in the design and construction of tall buildings, especially in concrete and composite structural systems. The method presented in the PCA report is the most widely used for the analysis of column shortening, but results can be very different depending on the time function of shrinkage suggested ...

COMPOSITION ESTIMATORS FOR A DISTILLATION COLUMN: THEORY AND EXPERIMENTS
IFAC Proceedings Volumes, 1995Abstract This work is a contribution to the development of non-linear estimators based on the Extended Kalman Filter theory to monitor the dynamics of a continuous distillation column. The performances of the estimators are checked by comparison with the behavior of a pilot distillation unit where fractionations of ethanol-water binary mixtures are ...
