Sound localization for a robot or an embedded system is usually solved by using Interaural Phase Di erence (IPD) and Interaural Intensity Di erence (IID). These values are calculated by using Head-Related Transfer Function (HRTF). However, HRTF depends on the shape of head and also changes as environments changes. Therefore, sound localization without HRTF is needed for real-world applications....

The main purpose of this work is to investigate the solutions, periodic character and study global asymptotic behavior so- lutions following rational di↵erence equation x_(n+1) = x_(n-2)*x_(n-6) / x_(n-3)*(±1 ± x_(n-2)*x_(n-6)) with a non-zero real numbers initial conditions.

Numerical simulation of uid ow in a hydrocarbon reservoir has to ac count for the presence of wells The pressure of a grid cell containing a well is di erent from the average pressure in that cell and di erent from the bottomhole pressure for the well Peaceman This paper presents a study of grid pressures obtained from the simulation of single phase ow through an isotropic porous medium using d...

The well-known necessary and su$cient condition to "nd a solution to the robust strictly positive real (SPR) problem, namely, that the phase di!erence of the polynomials involved must be less than p, was found to be also necessary and su$cient in the strengthened robust SPR problem by Anderson and Landau in a recent work, only for the continuous-time case. In this brief communication, we derive...

The e ect of the magnetic breakdown on the dHvA oscillation is studied by full-quantum numerical calculation for a two-dimensional model. We demonstrate that the interference di erence oscillation, usually designated as , exists even in the thermodynamic quantity; this result is contrary to the conventional semi-classical picture. In addition, the dependencies of various oscillations of the mag...

Instrumental variable (IV) estimates a causal e ect if the instrument satis es a monotonicity condition. When this condition is not satis ed, we only know that IV estimates the di erence between the e ect of the treatment in two groups. This di erence could be a very misleading measure of the treatment e ect: it could be negative, even when the e ect is positive in both groups. There are a larg...

Software testability is a misunderstood technology by most of the software test ing community Most testing experts believe that software testability is either a measure of complexity or a subjective assessment of how much it will cost to gen erate test cases perform coverage testing write drivers and or stubs etc This perspective is incomplete In the late s an alternative perspective on testa b...

To test a hypothesized faster-than-global sea-level acceleration along the mid-Atlantic United States, I construct a Gaussian process model that decomposes tide gauge data into short-term variability and longer-term trends, and into globally-coherent, regionally-coherent and local components. While tide gauge records indicate a faster-than-global increase in the rate of mid-Atlantic U.S. sea-le...

This paper evaluates the e¤ects of Seguro Popular on household and individual level health-related consumption, health spending, health outcomes, and labor supply. First introduced in 2002, Seguro Popular provides free health care to the …fty percent of Mexican families that lack the social security protections granted to all formal sector workers in that country. The Seguro Popular program was...

In this paper we present a nite di erence scheme for the discretization of the nonlinear PoissonBoltzmann(PB) equation over irregular domains that is second-order accurate. The interface is represented by a zero level set of a signed distance function using Octree data structure, allowing a natural and systematic approach to generate non-graded adaptive grids. Such a method guaranties computati...
