This paper introduces the Chinese BeiDou satellite system and its comparison with the actual completed American GPS and the Russian GLONASS systems. The actual BeiDou system consists of 14 satellites covering totally the Asia-Pacific area. A Single Point Positioning (SPP) test has been realised in Changsha, Hunan province, China, to show the advantage of using combined pseudorange solutions fro...

A time domain method is presented for analyzing simultaneous measurements of pressure and the horizontal components of velocity obtained beneath irregular multidirectional wave fields. This new method differs from the usual linear directional analyses applied to PUV data in two important aspects. First, the essential nonlinearity of the measured waves is not sacrificed to achieve a solution. Th...

purpose: to determine the sensitivity and specificity of posterior corneal elevation in discriminating keratoconus and subclinical keratoconus from normal corneas by galilei and orbscan ii diagnosed on the basis of topography. methods: three groups (keratoconus, subclinical keratoconus and normal) were evaluated with galilei and orbscan ii and results were compared to those obtained by gold sta...

Background: Neuromarketing ethical issues are debatable from two perspectives:  First, the effect that ethics has on consumer behavior through sensory, emotional, and emotional foundations of neuromarketing. Second, there are challenges in using neuromarketing and the need to codify ethical standards. The purpose of this study was to present a model of ethical dimensions of neuromarketing to at...

the aim of this study was to analyze the incidence of stage of embryonic development, embryo quality and the time of transfer on pregnancy rate in embryo transfer program timed. we were worked a total of 23holsteincowsasembryo donors, super-ovulated with gonadotropin of pregnant mare serum (pmsg) (2500 3000ui).69 cows were used as recipients of holstein dairy heifers with an age of20 months and...

Legacy-resolution base data on the NEXRAD network consists of reflectivity on a 1 km-by-1 deg polar grid and Doppler velocity and spectrum width on a similar 250 m-by-1 deg grid. It has been shown through simulations that mesocyclone and tornado signatures can be detected at ranges 50% greater than the current detectable ranges using higher-resolution base data on a 250 m-by-0.5 deg grid (Brown...

A novel method to provide high-resolution TwoDimensional Direction of Arrival (2D DOA) estimation employing Artificial Neural Networks (ANNs) is presented in this paper. The observed space is divided into azimuth and elevation sectors. Multilayer Perceptron (MLP) neural networks are employed to detect the presence of a source in a sector while Radial Basis Function (RBF) neural networks are uti...
