Abstract:
Many people sustain injuries while playing tennis due to improper methods of impacting the ball and insufficient muscle warm-up. A common injury of playing the backhand stroke would be either elbow flexor strain or extensor strain. It is popular to analyze the motion of backhand stroke using kinematics and kinetics of upper extremities. In this research, the LifeMOD™ module developed from a commercially available software, ADAMS, was used for simulation. The objective is to determine the relatively fitting parameters, using compared results obtained from LifeMOD™ and Matlab. According to vario

Abstract:
In traditional biomechanical analysis of upper limb, the high-precision motion data and lifelike human models are needed. It is obvious that those processes are costly and time-consuming. In this paper, a novel and simple combination method based on Kinect-LifeMOD is proposed. Firstly, the Microsoft Kinect (a latest depth sensor) is used to build a cheap and precise motion capture platform. Real-time and reliable key-node rotation data of human skeletons can be acquired by this motion capture system. Next, rotation data is converted into position data as the input of the LifeMOD software which

The DSC evidence offers the possibility to directly quantify the LiFe5Ox phase. Furthermore it allows one to obtain the enthalpies of formation of both LiFeO2 and LiFe5

A series of lithium iron phosphate /polypyrrole (LiFePO4/PPy) composite powders were synthesized by chemical oxidation method with different doping agent and oxidation agent. The composite powders were characterized by scanning electron microscopy (SEM), Fourier Transform Infrared Spectrum (FTIR), and X-ray diffraction (XRD). The results showed that the composite powders composed of PPy and LiFePO4. And the doping of polypyrrole in LiFePO4 could weaken the XRD intensity of LiFePO4 , but could not destroy its crystallization. With the increase of pyrrole in LiFePO4/ PPy composite powders, the p

A facile solid state method based chemical grinding method was applied to prepare high rate LiFePO4. SEM test results showed that the prepared LiFePO4(CG-LiFePO4) is more fine and uniform than that of the crude LiFePO4(C-LiFePO4) prepared by conventional solid state reaction method. Electrochemical measurement results indicated that CG-LiFePO4exhibited much better high-rate characteristic than crude one which delivered a stable discharge capacity of 140 mAhg-1, 126 mAhg-1at 0.5C rate and 2C rate respectively.

The presence of the surface organic species on the grafted LiFePO4/C powders was confirmed by X-ray photoelectron spectroscopy. Thermogravimetric analyses revealed a low loading (lower than 1 wt. %) of grafted molecules. The electrochemical characterization of the LiFePO4/C cathodes showed that a low loading of bromophenyl groups at the LiFePO4/C surface can enhance the rate of Li+ extraction, presumably due to

Abstract LiFePO4/C cathode material is largely used in Li-ion batteries due to its low toxicity, nonhazardous and high stability features. A facile and simple approach is proposed in LiFePO4/C production using low-cost materials. The effect of carbon addition during the formation of LiFePO4/C was investigated. Based on the XRD and FTIR analyses, olivine-structured LiFePO4/C cathode material was successfully obtained via methanol-based rheological method. The SEM result showed that the material has micron-sized polyhedral shape. The electrochemical performance tests were conducted in an 18,650-

LiFePO4 has attracted broad attention as a promising cathode material for lithium ion batteries.

LiFePO4/N-doped C composites with core–shell structures were synthesized by a convenient solvothermal method.
