The unavoidable speckle in SAR images seriously interferes with image quality and has a negative effect on subsequent interpretation. existing filters still need to be strengthened terms of both noise suppression edge preservation. Based this, novel non-local means filter by multi-directional local plane inclination angle (MDLPIA) is proposed. proposed uses the MDLPIA reconstruct new weight fun...

In this paper we discuss further properties of 2D correlation spectroscopy using the global phase angle intensity normalization method. The 2D global phase angle analysis method has been shown to discriminate against arbitrary signal amplitude changes not related to real correlation intensities. We have confirmed that the positive or negative sign of a global phase angle 2D correlation peak is ...

Background. Archery is a precision sport that requires high levels of consistency and reproducibility in the shooting movement to achieve the highest score. Objectives. This study aimed to compare and correlate the shooting time characteristics and shooting posture on the archery shooting performance of high- and low-performance archers. Methods. Terengganu state team and Malaysia Pahang Spor...

objective(s)bioelectrical impedance is the measure of impedance of the body. impedance consists of electric resistance and reactance. phase angle (pa) is the tan value of the ratio of reactance versus electric resistance. pa depends on cell membrane integrity and on body cell mass. there exists a correlation between pa values and body cell mass.the objective of this study was to compare the pa ...

With the purpose to establish a relationship between physical characteristics of the players and biomechanical variables of service in lawn tennis present study was structured. For the purpose of the study twelve intervarsity level players were recruited as the subjects. A camcorder was used to video record the movement of the subjects. 2D Data were collected from movement onset to the follow-t...

Bioelectrical impedance phase angle has been recommended as a tool to assess nutrition state, but there are no measuring devices have been specially designed for hospital residents. In this study, a system was established for the measurement of bioelectrical impedance phase angle. The electrical composition, calculation method and measuring method of this system are presented in this paper. Exp...

This paper examines the importance of load phase angle variations with respect to fatigue damage. The operating loads on a generic three bladed up-wind 1.5-MW wind turbine blade were analyzed over a range of operating conditions, and an aggregate probability distribution for the actual phase angles between the peak in-plane (lead-lag) and peak out-ofplane (flap) loads was determined. Using a fi...

An advanced guidance law is developed for reentry phase of a reentry vehicle. It can achieve small miss distance and desired impact attitude angle, simultanceously. To meet this requirment a guidance law based on the fuzzy logic approach is developed. It is partitioned into three stages. This guidance law does not require linearization of missile engagement model. Line-of-sight and flight path ...
