    Typical method on assessing the human breathing characteristics is based on measurements of breathing air parameters. Another possible method for human breathing assessment is through the analysis of respiratory muscles electromyography (EMG) signal. The EMG signal from different breathing task will be analyzed in order to determine the characteristics of the EMG signal pattern. Thus, feature extraction need to be done on the EMG signals. This paper  will look into the use of Mel-Frequency Cepstral Coefficients (MFCC) in providing the features for EMG signal. Analysis is done using different data analysis frame sizes. EMG signal classification is done using K-Nearest Neighbour. Results shows that MFCC is a good feature extraction method for this purpose with classification accuracy exceeds more than 90% for data analysis frame size of 2000 ms, 4000 ms, 5000 ms and 10000 ms

    Aerospace Medicine and Biology: A continuing bibliography with indexes, supplement 237

    Get PDF
    A bibliography is given on the biological, physiological, psychological, and environmental effects to which man is subjected during and following simulated or actual flight in the Earth's atmosphere or in interplanetary space. References describing similar effects of biological organisms of lower order are also included. Such related topics as sanitary problems, pharmacology, toxicology, safety and survival, life support systems, exobiology, and personnel factors receive appropriate attention. In general, emphasis is placed on applied research, but references to fundamental studies and theoretical principles related to experimental development also qualify for inclusion

    Selected topics in surface electromyography for use in the occupational setting: expert perspectives

    Get PDF
    "e various chapters in this compilation discuss surface electromyography as it can be applied to ergonomic studies. Topics include aspects associated with the use of electromyography for the study of ergonomic problems; the anatomic and physiologic information fundamental to understanding the recording and subsequent study of the electrical activity of muscles using surface electromyographic techniques; the fundamentals of recording electromyographic data during activities of interest to the ergonomist or in the setting where ergonomic activities are performed; the instrumentation required to obtain information from the electromyographic signal (including discussions of the relationship between temporal aspects of electromyography and anatomically associated movement, the relationship between electromyography and the production of force, and the relationship between electromyography and muscle fatigue); output forms for data analysis and applications interpretation of the electromyographic signal; functional muscle and the effects on electromyographic output; and the applications of electromyography in ergonomics." - NIOSHTIC-2"Editor in chief, Gary L.

    Workshop on Countering Space Adaptation with Exercise: Current Issues

    Get PDF
    The proceedings represent an update to the problems associated with living and working in space and the possible impact exercise would have on helping reduce risk. The meeting provided a forum for discussions and debates on contemporary issues in exercise science and medicine as they relate to manned space flight with outside investigators. This meeting also afforded an opportunity to introduce the current status of the Exercise Countermeasures Project (ECP) science investigations and inflight hardware and software development. In addition, techniques for physiological monitoring and the development of various microgravity countermeasures were discussed
