The sensation of two-way feedback of body is a special system of human reaction, which maintains and regulates symmetry and balance of human body. The human two-way feedback reacts to human health. For human overall health and delay decrepitude, it is necessary to pay attention to the stimulations (passive acceptance and initiative interventions) and relevant influences in human body and the stimulative effect. In this paper, the experimental research of stimulation and an example of two-way feedback in human body are given. And lay a foundation of prevention, medical treatment and hygiene of human overall health.展开更多

A general kinematic model of the space robot was established based on the law of linear and angular momentum conservation. A combinational joint model was established combined with bionic joint and closed motion. The attitude transformation of planar,two DOF and three DOF is analyzed and simulated by the model,and it is verified that the feasibility of attitude transformation in three DOF space. Finally,the specific scheme of disturbance elimination in attitude transformation is presented and simulation results are obtained.Therefore,the range of application field of the bionic joint model has been expanded.展开更多

The world scientific community was astonished by these observations, and since then until today, countless calculations have been made that only leave the hypothesis of the existence of an unknown <em>cosmic entity</em> that has the particularity of repelling matter from each other when it is sufficiently separated by huge amounts of that entity, which was called as “<em>dark energy</em>”. This “<em>dark energy</em>” is a completely unknown thing, and it is understood by some researchers as the convenient hypothesis, because it is which emerges from deep calculations and observations. Bearing in mind that we already know about all cosmic objects and systems are in rotation, both locally and not so locally, and that everything is full and endowed with intrinsic and extrinsic angular momentum, it seems logical to think that <em>rotational dynamics</em> must also apply to the more extensive, and that if locally (and not so locally) we perceive and infer rotating objects everywhere, then they must also exist globally. So, starting from the idea that rotation is omnipresent, at every level of sizes;from the invisibly small to the invisibly large, I thought that it is really wise to cover it through <em>rotation dynamics</em>, or that in the worst case, we cannot ignore the fact of the omnipresent rotation in any entity to infer. And this is the main reason for the resolution and the motivation of the birth of the publication of this study. Based on this seemingly simple idea, these results and conclusions of this study was reached: following a formal logic and evidence of the accelerated unfolding of the cosmic fabric, another hypothesis is proposed as an alternative to the existence of the “<em>dark energy</em>”: The <em>intensities of centrifugal acceleration fluxes</em> exceed the <em>intensities of gravitational fluxes</em>, which are not sufficient to compensate for the <em>centrifugal flux</em>, which is why baryonic and exotic matter, energy, space and time are extended, in geometric progression with respect to our apparent time. So, this unfolding of the cosmic fabric might not be caused by a “<em>dark energy</em>”, but by <em>centrifugal fields of rotational-orbital domains</em>. Besides all the above, this publication has a double purpose, because it is also intended to cover another matter;these deep attentions to the Rotational Dynamics also derive in another solution or hypothesis regarding the formed mystery after observing the incoherent too high velocity of matter in the far latitudes in spiral galaxies: The hypothesis of the existence of the so-called “<em>dark matter</em>” arises from the observation that, in spiral galaxies, all that matter which is located beyond a critical distance from the galactic rotation axis, travels too fast, while the calculations illustrate an insufficient intensity of <em>gravitational acceleration flux</em> to explain that speed and to retain all that matter while maintaining the orbital distance. However, the concept I present here, is that, in a spiral galaxy, all those matter which is positioned farthest from the <em>main rotation axis</em>, is effectively lost in space as time goes by, or what is the same, the <em>intensity of the centrifugal acceleration field</em> is not compensated by that of the <em>gravitational field</em>, and the destiny of every spiral galaxy is a more or less homogeneous and compact disk-shaped galaxy. As a basic NOTE to be taken into account;in the present article we intend to show the radical, meticulous and delicate relation that exists in the considerations of the <u>classic concept of “<em>isolated system of particles</em>”</u>, with the <u>degrees of the consistencies of the connections between all those “<em>particles</em>”</u>, whether they are inter-material bonds, or, in a relativistic scope, bonds between the same cosmic fabric. And this is so, because the idea of “<em>isolated</em>” falls directly and precisely on the criterion that we put to the <u>degree of consistency of each connection between each “<em>part</em>” or “<em>particle</em>”</u> that integrates the presumed and inferred concept of “<em>isolated system</em>” with respect to the rest of systems or universe.展开更多
