The authors have applied a systems analysis approach to describe the musculoskeletal system as consisting of a stack of superimposed kinematic hier-archical segments in which each lower segment tends to transfer its motion to the other superimposed segments. This segmental chain enables the derivation of both conscious perception and sensory control of action in space. This applied systems analysis approach involves the measurements of the complex motor behavior in order to elucidate the fusion of multiple sensor data for the reliable and efficient acquisition of the kinetic, kinematics and electromyographic data of the human spatial behavior. The acquired kinematic and related kinetic signals represent attributive features of the internal recon-struction of the physical links between the superimposed body segments. In-deed, this reconstruction of the physical links was established as a result of the fusion of the multiple sensor data. Furthermore, this acquired kinematics, kinetics and electromyographic data provided detailed means to record, annotate, process, transmit, and display pertinent information derived from the musculoskeletal system to quantify and differentiate between subjects with mobility-related disabilities and able-bodied subjects, and enabled an inference into the active neural processes underlying balance reactions. To gain insight into the basis for this long-term dependence, the authors have applied the fusion of multiple sensor data to investigate the effects of Cerebral Palsy, Multiple Sclerosis and Diabetic Neuropathy conditions, on biomechanical/neurophysiological changes that may alter the ability of the human loco-motor system to generate ambulation, balance and posture.

A mathematical Model to Predict Transition-to-Fatigue During Isometric Exercise on Muscles of the Lower Extremities

引用

Engineering（科研） 2012年第10期4卷 16-19页

作者： Jorge Garza-Ulloa Huiying Yu T. Sarkodie- Gyan Pablo Rangel Olatunde Adeoye noe vargas hernandez Department of Electrical and Computer Engineering UTEP El Paso Texas USA Mechanical Engineering Department UTEP El Paso Texas USA

Surface Electromyography (sEMG) activities of the four muscles were studied from twelve healthy subjects to analyze muscle fatigue. Data were recorded while subjects performed isometric exercises for a period of time until fatigue. The signal was segmented with 5000 samples to enable the evolutionary process. Based on the mean power spectrum and Median Frequency (MDF) of each segment, we developed a methodology that is able to detect the signal into a meaningful sequence of Non-Fatigue to Transition-to-Fatigue. By identifying this transitional fatigue stage, it is possible to predict when fatigue will occur, which provides the foundation of the automated system that has the potential to aid in many applications of our lives, including sports, rehabilitation and ergonomics.

Sale of the Crown of Beer： A Study Based on the Strategy Tripod of Mike Peng

引用

Sociology Study 2015年第10期5卷 817-824页

作者： Jose G. vargas-hernandez noe Rene Luna Plascencia University of Guadalajara Mexico

The main objective of this study is to analyze through tripod strategy Peng, the basics of why the acquisition and sale of Grupo Modelo （which it is the largest brewer in Mexico with the highest market share） through analysis of the annual reports of the company. The analysis will be supported under three main theories： theory of industry, theory of resources and capabilities, and ultimately theory of institutions. The paper concludes with a compilation and analysis of information giving rise to answer the question why 6rupo Modelo sold？ And if have you had a positive result in the acquisition of Grupo Modelo by the company ABI？ The answer is yes. The sale price of the shares by Grupo Modelo was very high and it received an award of 30% over the closing price of the shares of the C series in 2012. So it was a good sale regarding previous observations.
