An efficient algorithm for band connectivity (BC) resoln. is presented. The method uses only readily available band coeffs. and the overlap matrix, and has a low computational cost. The accuracy of the BC resoln. is such that the method is practical for me ...
The Derjaguin approximation states that the interaction force between two curved surfaces is proportional to their effective radius, whereby the inverse effective radius is the arithmetic mean of the inverse curvature radii of the surfaces involved. The pr ...
The friction force on a nanometer-sized tip sliding on a surface is related to the thermally activated hopping of the contact atoms on an effective atomic interaction potential. A general analytical expression relates the height of this potential and the h ...
Cartography is one of the major application areas using geographical databases. Whether it is for the business of producing paper maps for sale, or whether it is for displaying maps on a screen to visualize the result of a query, we need computer systems t ...
We study the electrodynamics of a superconductor superlattice consisting of layers of two kinds (wide layers with extremely weak pinning and very thin layers with-strong pinning), in a perpendicular magnetic field. The problem is treated with the nonlocali ...
In this study, the multiaxial fatigue strength of full-scale transversal attachment is assessed and compared to original experimental results and others found in the literature. Mild strength S235JR steel is used and an exploratory investigation on the use ...
The low frequency complex ac impedance Z of c-axis oriented YBa2Cu3O7 thin films was measured as a function of the applied magnetic field B. At temperatures not too close to the transition temperature the imaginary part of Z is proportional to B2, while th ...
The author studies properties of the Bordoni peak in 99,999 % gold. The following features are considered : influence of type and rate of coldwork on relaxation strength. After traction coldwork, the height of the Bordoni peak is roughly proportional to th ...
Using a low-level representation of images, like matching pursuit, we introduce a new way of describing objects through a general description using a translation, rotation, and isotropic scale invariant dictionary of basis functions. We then use this descr ...
Low-frequency losses in weakly anharmonic cubic centrosymmetric crystals as a function of permittivity are estimated using phonon kinetics approach. It is shown that very steep dependencies up to the fifth power of permittivity (epsilon'' is-proportional-t ...
