We explore the ability of directional nuclear-recoil detectors to constrain the local velocity distribution of weakly interacting massive particle (WIMP) dark matter by performing Bayesian parameter estimation on simulated recoil-event data sets. We discuss in detail how directional information, when combined with measurements of the recoilenergy spectrum, helps break degeneracies in the veloci...

In this paper we present a novel, robust and efficient GPU based technique to automatically generate a Navigation Mesh for complex 3D scenes. Our method consists of two steps: firstly, starting with a 3D scene representing a complex environment of one floor with slopes, steps, and other obstacles, it automatically generates a 2D representation based on a single polygon (floor) with holes (obsta...

We investigate the accuracy attainable by forthcoming space-based observations of the cosmic microwave background (CMB) temperature and polarization anisotropy in constraining the dark energy density parameter ΩQ and equation of state wQ = pQ/ρQ. Despite degeneracies among parameters, it is possible for high precision observations such as those from the Wilkinson Microwave Anisotropy Probe and ...

We study the effects of halo substructure and a distribution in the concentration parameter of haloes on large-scale structure statistics. The effects on the power spectrum and bispectrum are studied on the smallest scales accessible from future surveys. We compare halo-model predictions with results based on N -body simulations, but also extend our predictions to 10kpc scales which will be pro...

The spectroscopic regularities of modern empirical data on the nonstrange mesons up to 2.4 GeV can be summarized as a systematic clustering of states near certain values of energy. It is getting evident that some unknown X-symmetry triggers the phenomenon. We perform a thorough phenomenological check of a recently proposed formula M 2 ∼ L + n, which explains the X-symmetry. A semiclassical hadr...

nutrition has a significant effect on reproduction and lactation in ruminant. supply of require nutrient of dairy cows and ewes in early lactation is the main challenges that will be considered, since in most cases the animals facing negative energy balance after calving and the beginning of the period of lactation. negative energy balance may sometimes result in reduced livestock production an...

In the framework of piezoelectric energy harvesting, this work focused on quantification ultimate conversion capability various ferroelectric ceramics and single crystals. Energy was achieved by application Ericsson cycles under high electric field mechanical stress. The main aim approach to experimentally apply electromechanical several key materials. This process decomposed into four steps, w...

Reactor experiments offer a promising way to determine θ13 and are free from parameter degeneracies in neutrino oscillations. It is described how reactor measurements of sin 2θ13 can be improved by a near-far detector complex. The experimental lower bound is derived on the sensitivity to sin 2θ13 & 0.02 based on the rate analysis, and an idea is given which may enable us to circumvent this boun...
