Body motion wave

Keywords— autonomic nervous system, unconscious response, body motion wave (BMW), dynamic air pressure sensor, satisfaction. [Pg.420]

Here, in subject s body at sleep some continuous motions are generated resulting in respiration, pulse and other unconscious action et al, so that thus motions are detected as pressure waves. Thus obtained pressure waves here are neither electrocardiogram nor respiration gas. All waves express body motions. Therefore, we named this wave body motion wave . This wave was filtered to two waves at this paper in Fig.4. The one is respiration-origin BMW, R-BMW and the other is pulse-origin BMW, P-BMW . [Pg.421]

For gas-phase molecules the assumption of electronic adiabaticity leads to the usual Bom-Oppenheimer approximation, in which the electronic wave function is optimized for fixed nuclei. For solutes, the situation is more complicated because there are two types of heavy-body motion, the solute nuclear coordinates, which are treated mechanically, and the solvent, which is treated statistically. The SCRF procedures correspond to optimizing the electronic wave function in the presence of fixed solute nuclei and for a statistical distribution of solvent coordinates, which in turn are in equilibrium with the average electronic structure. The treatment of the solvent as a dielectric material by the laws of classical electrostatics and the treatment of the electronic charge distribution of the solute by the square of its wave function correctly embodies the result of... [Pg.64]

This means that the vectors a and b are parallel Thus, the potential waves Up are characterized by the fact that in their case particle displacement occurs in the direction of wave propagation. Therefore, the particle motion associated with this type of waves is always in the direction of wave propagation, and it consists of alternating condensations and rarefactions of the particles within the elastic body. Such waves are described as compressional waves. [Pg.404]

Schiehlen and Seifried (Chapter 9) elaborately describe the impact on beams that resnlts in large rigid body motions and small structural waves. Such mechanical systems are often modeled as multibody systems to describe the large nonlinear motion where the impacts are treated by the coefficient of restitution. The coefficient of restitution is considered as deterministic number depending on the material, the shape and the... [Pg.638]

Radiation is the transfer of heat from one body to another, not in contac t with it, by means of wave motion through space. [Pg.554]

Expansion waves are the mechanism by which a material returns to ambient pressure. In the same spirit as Fig. 2.2, a rarefaction is depicted for intuitive appeal in Fig. 2.7. In this case, the bull has a finite mass, and is free to be accelerated by the collision, leading to a free surface. Any finite body containing material at high pressure also has free surfaces, or zero-stress boundaries, which through wave motion must eventually come into equilibrium with the interior. Expansion waves are also known as rarefaction waves, unloading waves, decompression waves, relief waves, and release waves. Material flow is in the same direction as the pressure gradient, which is opposite to the direction of wave propagation. [Pg.21]

Use of the Born-Oppenheimer approximation is implicit for any many-body problem involving electrons and nuclei as it allows us to separate electronic and nuclear coordinates in many-body wave function. Because of the large difference between electronic and ionic masses, the nuclei can be treated as an adiabatic background for instantaneous motion of electrons. So with this adiabatic approximation the many-body problem is reduced to the solution of the dynamics of the electrons in some frozen-in configuration of the nuclei. However, the total energy calculations are still impossible without making further simplifications and approximations. [Pg.19]

The theory behind body-fixed representations and the associated angular momentum function expansions of the wavefunction (or wave packet) in terms of bases parameterized by the relevant constants of the motion and approximate constants of the motion is highly technical. Some pertinent results will simply be stated. The two good constants of the motion are total angular momentum, J, and parity, p = +1 or 1. An approximate constant of the motion is K, the body-fixed projection of total angular momentum on the body-fixed axis. For simplicity, we will restrict attention to the helicity-decoupled or centrifugal sudden (CS) approximation in which K can be assumed to be a constant of the motion. In terms of aU its components, and the iteration number k, the real wave packet is taken to be [21]... [Pg.11]

At this stage the assumption that the wave function ip can be factorized into com and relative-motion (rm) components, by defining E = Ecom + Erm, is commonly made. In terms of ip = body problem is decoupled into two one-body problems ... [Pg.335]

It seems quite natural to describe the extended part of a quantum particle not by wavepackets composed of infinite harmonic plane waves but instead by finite waves of a well-defined frequency. To a person used to the Fourier analysis, this assumption—that it is possible to have a finite wave with a well-defined frequency—may seem absurd. We are so familiar with the Fourier analysis that when we think about a finite pulse, we immediately try to decompose, to analyze it into the so-called pure frequencies of the harmonic plane waves. Still, in nature no one has ever seen a device able to produce harmonic plane waves. Indeed, this concept would imply real physical devices existing forever with no beginning or end. In this case it would be necessary to have a perfect circle with an endless constant motion whose projection of a point on the centered axis gives origin to the sine or cosine harmonic function. This would mean that we should return to the Ptolemaic model for the Havens, where the heavenly bodies localized on the perfect crystal balls turning in constant circular motion existed from continuously playing the eternal and ethereal harmonic music of the spheres. [Pg.508]

Conductive and Convective Heat Transfer, Thermo Explosion by. There are three fundamental types of heat transfer conduction, convection radiation. All three types may occur at the same time, but it is advisable to consider the heat thransfer by each type in any particular case. Conduction is the transfer of heat from one part of a body to another part of the same body, or from one body to another in physical contact with it, without appreciable displacement of the particles of either body. Convection is the transfer of heat from one point to another within a fluid, gas or liquid, by the mixing of one portion of the fluid with another. In natural convection, the motion of the fluid is entirely the result of differences in density resulting from temp differences in forced convection, the motion is produced by mechanical means. Radiation is the transfer of heat from one body to another, not in contact with it, by means of wave motion thru space (Ref 5)... [Pg.279]
