We use N-body simulations to study evolution of galaxy clusters over the redshift interval 0 z 0.5 in cosmological models with a mixture of cold and hot dark matter (CHDM). Four di erent techniques are utilized: the cluster-cluster correlation function, axial ratios and quadrupoles of the dark matter distribution in individual clusters, and virial properties. We nd that the correlation function...

We studied the in-plane magnetic anisotropy of rf ~radio frequency! sputtered @~FeTaN!/~TaN!#n multilayers synthesized on Si substrates. In the multilayers where n55, the FeTaN thickness is fixed at 30 nm and the thickness of TaN, tTaN , is varied from 0 to 6.0 nm, we observed a clear trend that, with increasing tTaN , the values of coercivity, grain size, and amplitude of maximum magnetoresist...

Large strains, anisotropy of mechanical properties of materials and Coulomb friction in contact regions are some properties in the analysis of deep drawing process. In this research, the effects of different parameters such as anisotropy coefficient, work hardening exponent and friction coefficient on deep drawing process of drawing quality steel are studied. For this purpose, the finite elemen...

Cohesive-frictional soils are widely used in the construction of embankment structures and due to the method of construction, i.e. applying compactive efforts in the vertical direction in these cases, the occurrence of anisotropy in the soil strength and permeability seems to be inevitable. In this study, attempts have been made to evaluate the shear strength of c-f soils through modifying a l...
