This study analyzed that the penetration of electromagnetic waves through an unknown opening in a large enclosure generated standing within enclosure, thereby reducing its shielding characteristics. A 3D numerical analysis confirmed performance can be improved by using absorbers to reduce wave. was verified experimentally.
Abstract In order to study the formation and penetration behavior of triple-layer reactive composite EFP, numerical simulation method is used describe process, reveals influence blasting height on penetration. The results show that process EFP includes impact, boost stretching flight stages. impact stage: under detonation wave product, outer, middle inner liners collide with each other, kinetic...
T paper develops a framework for measuring “tipping”—the increase in a firm’s market share dominance caused by indirect network effects. Our measure compares the expected concentration in a market to the hypothetical expected concentration that would arise in the absence of indirect network effects. In practice, this measure requires a model that can predict the counterfactual market concentrat...
This paper examines strategies of standard software vendors, in view of the existence of network effects on standard software markets. In particular, we analyze if and under which conditions penetration pricing can be considered as a promising strategy. Our work is based on a simulation model, which provides the opportunity to examine the impact of alternative pricing strategies on the distribu...
– We compute the optical conductivity of 2D f-wave superconductors and also of the multigap model proposed recently by Zhitomirsky and Rice at T = 0K in the Born limit. The presence of interband impurity scattering was found to play an important role: the contributions from the two bands mix up, and new structures are seen in the tunneling density of states and in the optical spectrum as well, ...
In the present study, the three-dimensional elastic discrete element method (DEM) and the elastic finite element method (FEM) analysis were, respectively, applied to the randomly distributed identical spheres as a granular target and to the cylindrical projectiles in order to clarify dynamic response during penetration. In the target, it was found that highly densified region was formed just ah...
The steady growth of broadband penetration and the ongoing progress in networking technologies have increased the importance of home networks in the provision of high quality internet services. Market stakeholders have cooperated to evolve home networking towards an integrated, converged Gigabit technology, which will completely change the Home Area Networks (HANs) landscape and will enable a w...
We study the thermal fluctuations of anisotropic order parameters (OP) in lay-ered superconductors. In particular, for copper oxides and a d-wave OP, we present some experimental consequences of fluctuations in the direction normal to the layers. It is shown that the c-axis penetration depth λ c can have a " disorder-like " quadratic temperature dependence at low temperature. The fluctuations a...
The problem of optical ray propagation in a nonuniform random half-plane lattice is considered. An external source radiates a planar monochromatic wave impinging at an angle theta on a half-plane random grid where each cell can be independently occupied with probability q(j)=1-p(j),j being the row index. The wave undergoes specular reflections on the occupied cells, and the probability of penet...
Nonlinear Optical Spectroscopy of Solid/Solid Interfaces Mohsen S. Yeganeh Arjun G. Yodh Three-wave mixing (3WM) spectroscopy is an exciting and relatively unexplored probe of buried solid interfaces. It possesses long penetration depths characteristic of most optical methods and intrinsic interface specificity characteristic of second-order optical processes. In this thesis we present frequenc...
