A new theory of elastodynamic homogenization is proposed, which exploits the integral equation form of Navier’s equations and relationships between length scales within composite media. The scheme is introduced by focusing on its leading-order approximation for orthotropic, periodic fibre-reinforced media where fibres have arbitrary cross-sectional shape. The methodology is general but here it ...

We emphasize the importance of identifying non-exotic SUfl(3) partners of the Θ pentaquark, and indicate possible ways how to do it. We also use the soliton picture of baryons to relate Reggeon couplings of various baryons. These relations are used to estimate the Θ production cross section in high energy processes. We show that the corresponding cross sections are significantly suppressed rela...

Motivated by the requirements of the present archaeology, we have been developing an automated archivation system for archaeological classification and reconstruction of ceramics. Our system works with the profile of an archaeological fragment, which is the cross-section of the fragment in the direction of the rotational axis of symmetry. Ceramic fragments are recorded automatically by a 3D-mea...

We study the impact of the halo shape and geometry on the expected weakly interacting massive particle (WIMP) dark matter annihilation signal from the galactic center. As the halo profile in the innermost region is still poorly constrained, we focus on geometrical distortions and consider different density behaviors like flat cores, cusps and spikes. We show that asphericity has a strong impact...

the entrainment of a stably stratified layer into a turbulent mixed layer in a confined region has been studied in the laboratory for different richardson numbers, ri. the results include direct observation of turbulent characteristics and density measurements using two high precision salinity meters. the measurements include turbulence intensity, scale of eddies near the interface and energy s...

Design criteria of low-cost, dual-concentric metasurface possessing wideband phase gradient (PG) are introduced. The radar cross-section reduction (RCSR) is explained by anomalous reflection that characterizes the superficial planar. geometry consists two single band RCSR modulated surfaces (MSs) triggered in each other. Each MS built-up square patch (SP) unit cells configured as a modulation s...
