Semiconductor Superlattices and Interfaces. Proceedings of the International School of Physics “Enrico Fermi”

This e-book is worried with the dynamic box of semiconductor microstructures and interfaces. a number of subject matters within the primary homes of interfaces, superlattices and quantum wells are integrated, as are papers on progress strategies and functions. The papers care for the interplay of thought, experiments and functions in the box, and the exceptional contributions are from either the educational and business worlds

International Electronics Directory '90. The Guide to European Manufacturers, Agents and Applications

Overseas Electronics listing '90, 3rd version: The consultant to eu brands, brokers and functions, half 1 includes a listing of varied brands in Europe and a listing of brokers in Europe. This e-book encompasses a categorized listing of digital services the place either brands and brokers are indexed.

Field and Service Robotics: Results of the 8th International Conference

FSR, the foreign convention on box and repair Robotics, is the best unmarried tune convention of robotics for box and repair purposes. This e-book offers the result of FSR2012, the 8th convention of box and repair Robotics, which was once initially deliberate for 2011 with the venue of Matsushima in Tohoku area of Japan.

Supercomputing: 29th International Conference, ISC 2014, Leipzig, Germany, June 22-26, 2014. Proceedings

This e-book constitutes the refereed court cases of the twenty ninth foreign Supercomputing convention, ISC 2014, held in Leipzig, Germany, in June 2014. The 34 revised complete papers offered jointly have been conscientiously reviewed and chosen from seventy nine submissions. The papers disguise the subsequent subject matters: scalable purposes with 50K+ cores; advances in algorithms; clinical libraries; programming types; architectures; functionality types and research; computerized functionality optimization; parallel I/O and effort potency.

When the value of Cf /C is smaller (very weak bedding planes), the anisotropy of UCS is stronger. But for all the values of Cf /C considered, the minimum of UCS is found for α = 30◦. Consider now the influence of frictional angle. 8 10 0 0 15 30 45 60 75 90 Orientation ( ) interfaces and bedding planes.  3, the variation of UCS with loading orientation is presented. Again, it is clear that the anisotropy of UCS depends on the frictional coefficient of bedding planes. The anisotropy of UCS is more significant with smooth bedding planes than for rough ones.

The top and bottom boundaries are confined by rigid platens and by the vertical normal stress σy. The left and right lateral walls are confined by semi-rigid walls and by the minor principal stress σx. The sample is first loaded isotropically during consolidation, then sheared by rotating the lateral walls. Shearing is performed under constant angular velocity and constant vertical and horizontal normal stresses. The constant normal stresses applied to the top and lateral boundaries are applied by a numerical servo-control.

It is known in the literature that a DEM model with more than 5,000 particles provides a representative element volume for the modeling of the stress-strain response of granular materials. In this study, the number of randomly generated particles ranged from 6,556 to 16,190. Circular particles are used but, as discussed above, rolling resistance is employed to partly account for the effects of non-circular and irregular particle shapes (Mohammed and Gutierrez 2010). The rolling resistance parameter α is affected by the particle shape, normal stiffness and normal force at a point of contact and typically ranges from 0 to 1 (Mohammed and Gutierrez 2010).
