Unanchored steel storage tanks are used in industrial plants to store oil and other petrochemical liquids. In a major earthquake, such may sustain different types of damage, including elasto-plastic buckling the shape an elephant's foot, which is object research. The methodology introduced this paper consists cloud-based 1D site response analysis (SRA) pushover-based seismic performance assessm...

In the modern world, government policy makers engage in the decision making process to pursue the interests of their countries. Think tanks play a significant role in this complicated process by giving advice to decision makers. Since the beginning of the twentieth century, think tanks increasingly emerged in the world, especially in Western European countries and the United States of America (...

in this work, mathematical modeling of microbial(trichosporon sp.) biomass production in a stirred tankbioreactor and in an external airlift bioreactor has beeninvestigated. a model based on a tanks-in-seriesmodel without back-flow has been used to simulate theproduction of single cell protein in the external airliftbioreactor under an unsteady condition and withoutoxygen limitation, utilizing ...

A rotationally invariant random interaction ensemble was realized in a single- j fermion model. A statistical approach reveals the random coupling of individual angular momenta as a source for the empirically known dominance of ground states with zero and maximum spin. The interpretation is supported by the structure of the ground state wave functions.

excited-sta,te charge distribution venting such a conformation. Extended Huckel calculations confirm this assumption. The potential energy curves for the rotation of the aldehyde group away from the plane of the phenyl ring for the ground state and the excited state of benzaldehyde arising from the carbonyl (n,n*) transition are shown in Figure 7. The calculated barrier to rotation is 0.22 eV f...

This paper introduces Open Planning Process Panels (O-P3). These panels are based on explicit models of the planning process and are used to coordinate the development and evaluation of multiple courses of action. We describe the generic ideas behind O-P3 technology, a general methodology for building O-P3 interfaces and two applications based on O-P3 technology: the Air Campaign Planning Proce...
