Potassium is an essential element for human metabolism. It is present in all living cells, predominantly in the skeletal muscle tissue. The energy of the 40K photon and its uniform distribution within the human body allow its in vivo measurement. Subjects of both sexes were monitored at the whole-body counter of the IRD facility for the evaluation of 40K body burden, being divided into two groups: (1) subjects who do not exercise routinely, and (2) subjects who do exercise routinely. The average values found for potassium mass and potassium concentration in group 1 were 99 +/- 17 g of K and 1.3 +/- 0.2 g of K kg(-1) of body mass, respectively, and in group 2 the average values found for potassium mass and potassium concentration were 118 +/- 33 g of K and 1.6 +/- 0.2 g of K kg(-1) of body mass, respectively. The comparison between average values for potassium mass and concentration shows a significant statistical difference. 相似文献

针对三维空间,提出了一种可以同时测量刚体9个惯性参数的新方法。利用气体静压轴承低速自由转动时其角速度是一个随时间衰减的单指数函数这一运动规律,测量物体绕任意轴的转动惯量,通过9次测量最终求出刚体的9个惯性参数。设计了一套物体惯性参数测量仪,该测量仪可以同时测量三维空间中物体的9个惯性参数。测量过程中无需重新装配,减少了中间测试量及人为干预误差,使测量时间缩短,测量精度提高。 相似文献

The purpose of this paper is to present a philosophical aspect of the ecology of human-machine systems by exploring the potential application of the basic pattern referred to as the golden section to workplace design and human body dimensions. Studies of stairway and industrial knife designs confirm that subjects prefer workplace and tool dimensions that are related to their human body segment lengths. In this paper, it is suggested that for each task or equipment there are different body segments which should be considered as a transitional element harmonizing a human body with its workplace. Hence, for a knife design - grip size circumference and blade length, for stairway design - length of foot and height of a riser. The psychophysical assessments affirm an existence of the golden section in workplace/tool design as a preferred design harmonizing an individual's body dimensions with work demands. 相似文献

Measurement of the human body anteflexion angle is an essential method for evaluating human flexibility. In this study, a method based on edge detection is proposed for measuring the angle of human body anteflexion. In this technique, an adaptive Gaussian filter is used to filter an image while preserving as much of its edge information as possible. A 5 × 5 template is adopted to calculate the gradient amplitude and direction of the image. Moreover, the Otsu algorithm is used to compute the high and low thresholds of the gradient image, thereby rendering the algorithm adaptive and eliminating any need for manual threshold setting. After the edges are obtained, the feature points of the head, buttocks, and foot are extracted to calculate the anteflexion angle of the human body. 相似文献

This study presents a new approach to classify human body poses by using angular constraints and variations of body joints. Although different classifications of the poses have been previously made, the proposed approach attempts to create a more comprehensive, accurate and extensible classification by integrating all possible poses based on angles of movement in human joints. The angular variations in all body joints can determine any possible poses. The joint angles from the body axis are computed in the three-dimensional space. In order to train and classify the pose in an automated manner, support vector machines (SVMs) were used. Experiments were carried out on both benchmark (CMU dataset) and in-house simulated (POSER dataset) poses to evaluate the performance of the proposed classification scheme. 相似文献

3-dimension (3-D) printing technology is growing strongly with many applications, one of which is the garment industry. The application of human body models to the garment industry is necessary to respond to the increasing personalization demand and still guarantee aesthetics. This paper proposes a method to construct 3-D human models by applying deep learning. We calculate the location of the main slices of the human body, including the neck, chest, belly, buttocks, and the rings of the extremities, using pre-existing information. Then, on the positioning frame, we find the key points (fixed and unaltered) of these key slices and update these points to match the current parameters. To add points to a star slice, we use a deep learning model to mimic the form of the human body at that slice position. We use interpolation to produce sub-slices of different body sections based on the main slices to create complete body parts morphologically. We combine all slices to construct a full 3-D representation of the human body. 相似文献
