In this paper we shall show that certain estimates for the Euclidean wave equation also hold on Riemannian manifolds with smooth, strictly geodesically concave boundaries. By the last condition, we understand that the second fundamental form on the boundary of the manifold is strictly positive definite. We shall then give two applications of our estimates. First, we shall show that if n is the ...

Cyclic averaging, as a method for reducing the leakage ermr in the estimatian of frequency response functions, is a simple and effective method that can be implemented in any data acquisit ion system. With the widespread availability of multikbamel data acqtisition systems, cyclic averaging may be the easiest approach to minimizing the huncation effect, known as leakage, that DccllIs when time ...

We investigate the response function of LISA and consider the adequacy of its commonly used approximation in the high-frequency range of the observational band. We concentrate on monochromatic binary systems, such as white dwarf binaries. We find that above a few mHz the approximation starts becoming increasingly inaccurate. The transfer function introduces additional amplitude and phase modula...

chess is considered as a cognitive game because of severe engagement of the mental resources during playing. the purpose of this study is evaluation of frontal lobe function of chess players with matched non-players. wisconsin card sorting test (wcst) data showed no difference between the player and non-player groups in preservation error and completed categories but surprisingly showed signifi...

To effectively improve the tire grounding behaviors of wheelchair robots, an analytical method is proposed to analyze and optimize the tire grounding safety. Firstly, taking the cushion and tires as the vibration isolation elements with stiffness and damping, the vertical vibration model of the human-wheelchair robot is established. Then, taking the random excitation as the typical input, the f...

In this study, the pure nano-structure hydroxyl apatite samples were synthesized via hydrolysis method. The powder samples were sintered at various temperatures of 500°C, 700°C and 900°C in a furnace. X-ray diffraction (XRD) and Fourier transform infra-red (FTIR) spectroscopy systems were used to characterize the synthsized samples. Comparison of the glow curves shows that the most ...

S U M M A R Y Robust magnetotelluric response function estimators are now in standard use in electromagnetic induction research. Properly devised and applied, these have the ability to reduce the influence of unusual data (outliers) in the response (electric field) variables, but are often not sensitive to exceptional predictor (magnetic field) data, which are termed leverage points. A bounded ...

The charge longitudinal response function is examined in the framework of the random-phase approximation in an isospin-asymmetric nuclear matter where proton and neutron densities are di erent. This asymmetry changes the response through both the particle-hole interaction and the free particle-hole polarization propagator. We discuss these two e ects on the response function on the basis of our...
