To obtain valid 3D joint angles with inertial sensors careful sensor-to-segment calibration (i.e. functional or anatomical calibration) is required and measured angular velocity at each sensor needs to be integrated to obtain segment and joint orientation (i.e. joint angles). Existing functional and anatomical calibration procedures were optimized for gait analysis and calibration movements wer...

It is believed that the basic component of the central engine of quasars, microquasars, and energetic Gamma Ray Bursts are the rotating or the Kerr Black Holes (BH)[1]. But by using a generic property[2-4] of the metric components of a stationary axisymmertic rotating metric in its standard form, namely, gφφ = sin 2 θgθθ, where φ is the azimuth angle and θ is the polar angle measured from the a...

in this paper, by considering a squint angle for synthetic aperture radar in the strip-map mode, a method is proposed for estimating parameters of a fixed acceleration moving target. non-zero doppler centroid and range-azimuth coupling in the squint mode add complexity to estimation equations of moving target parameters and cause doppler ambiguity. this, in turn, causes to lose the efficiency o...

In this paper, a Kelvin impulse theory model is constructed for restricted bubble through conformal transformation. The collapse dynamics of near right-angle wall are systematically investigated based on the result new theoretical and high-speed photography experiment. particular, jet, characterized by intensity angle impulse, visualized analyzed with experiment validations. corresponding resul...

In this work, the aerodynamic performance and optimization of a vertical-axis wind turbine with high tip-speed ratio are theoretically studied on basis two-dimensional airfoil theory. By dividing rotating plane into upwind downwind areas, relationship among angle attack, azimuth, pitch angle, is derived using quasi-steady model, loads then obtained. applying polynomial approximation to function...

This study presents a novel, highly detailed, and accurate modelling method for calculation of the total annual solar thermal energy received by double-slope still. The model is further utilized sensitivity analysis optimization with help Genetic Algorithm TOPSIS methods. reveals that main parameters can independently affect input are basin length, width, tilt angle, surface azimuth glass cover...

In order to be able injured from the PV panel at an inclined angle with a horizontal plane certain incline, they must turned approximately south. But, it is difficult obtain maximum efficiency November March when sun's rays are more oblique than in summer. benefit sun given months, solar positioned between and minimum values of azimuth angle. addition, shadow analysis should also done setup. th...

A general stochastic spatial MIMO channel model is proposed for evaluating various MIMO techniques in this paper. It can generate MIMO channels complying with various MIMO configurations such as smart antenna, spatial diversity and spatial multiplexing. The modeling method produces the stochastic fading involving delay spread, Doppler spread, DOA (direction of arrival), AS (angle spread), PAS (...
