Algebraic hyperstructures theory is a natural extension of the classical algebraic structures. Because of importance and new viewpoints in this theory, we try to apply this theory to the elementary particle physics and nuclear physics presenting the definitions and the concepts of the algebraic hyperstructures. In this work we intend to use this new branch of mathematics to describe the inte...
Dynamic structural responses via time history analysis are highly dependent to characteristics of selected records as the seismic excitation. Ground motion scaling is a well-known solution to reduce such a dependency and increase reliability to the dynamic results. The present work, formulate a twofold problem for optimal spectral matching and performing consequent sizing optimization based on ...
The theory of self-scaled conic programming provides a uniied framework for the theories of linear programming, semideenite programming and convex quadratic programming with convex quadratic constraints. Nesterov and Todd's concept of self-scaled barrier functionals allows the exploitation of algebraic and geometric properties of symmetric cones in certain variants of the barrier method applied...
nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹a‹63,from a microscopic theory, which includes nuclear pairing interaction. single particle levels for both seeger and nilsson potentials were used in the calcdations. level densities extracted from the theory are compared with their conesponding experimental values, it is found that the overall ...
The attenuation ability of composites containing micro and nano-sized WO3 was measured and compared with the attenuation ability of composites containing micro-size and nano-sized PbO for X-rays in diagnostic energy range. For the purpose, after synthesizing nano and micro-scaled particles, different percentages of them were imbedded in poly vinyl chloride (EPVC) emulsion and prepared as shield...
