O(N) Tight-Binding Algorithm for Large-Scale Molecular Dynamics Simulations

JaLCDOI	10.18926/19674
フルテキストURL	Mem_Fac_Eng_OU_33_2_71.pdf
著者	鶴田健二\| 東辻浩夫\| 東辻千枝子\|
抄録	A parallel tight-binding molecular dynamics with an order-N [O(N))] algorithm is implemented to perform large-scale simulation of nanostructured materials. The algorithm is based on the Fermi-operator expansion of an electronic energy and force, and we present its basic formalisms. Accuracy necessary for molecular-dynamics simulations can be obtained by a proper truncation in the expansion. Parallel efficiency on a parallel PC cluster shows nearly ideal scaling behavior with respect to the number of processors. Applicability of the method to a silicon-carbide system is examined.

Multicomponent Plasmas in Penning-Malmberg Traps

JaLCDOI	10.18926/19673
フルテキストURL	Mem_Fac_Eng_OU_33_2_61.pdf
著者	東辻浩夫\| 鶴田健二\| 東辻千枝子\|
抄録	The behavior of multicomponent plasmas in the Penning-Malmberg traps is discussed with the parameters corresponding to experiments with antiprotons and cryogenic electrons. The relaxation times for the energy transfer antiprotons to electrons and between parallel and perpendicular components of electrons are estimated. It is shown that, depending on the values of parameters, both the former and the latter can be the bottleneck in the cooling process.

Density Functional Molecular Dynamics of Hydrogen Plasma

JaLCDOI	10.18926/19671
フルテキストURL	Mem_Fac_Eng_OU_33_2_51.pdf
著者	東辻浩夫\| 鶴田健二\| 東辻千枝子\|
抄録	Density functional molecular dynamics method is applied to hydrogen plasma in the domain of liquid metallic hydrogen. Tentative results for the proton-proton pair distribution function and the electron-proton pair distribution function are obtained. It is shown that with the increase of the parameter γ(s), we have increasingly strong screening of proton charge by electrons and the decrease of electron density in the domain between protons.

Measurement System of Biomechanical Properties for Portable Use

JaLCDOI	10.18926/19666
フルテキストURL	Mem_Fac_Eng_OU_33_2_45.pdf
著者	Yamada Nobuya\| 岡久雄\|
抄録	It is difficult to evaluate a biomechanical properties quantitatively. The authors developed the measurement system of biomechanical properties formerly but it is on a large scale because of the use of personal computer. In this study, the portable measurement system of biomechanical impedance/mobility is developed. To establish a rapid measurement, a random vibration is adopted in input signal. The system consists of the measuring probe, amplifier, and a note-typed personal computer. The measurement probe is developed newly, and has an overall length of 9 ㎝ (without a handle) and a total weight of about 500 g. The measurement program is also developed and is available to any computer which is worked under MS DOS compatible in Windows 95/98 operating system. The biomechanical spectra of thigh, temple and forehead are obtained and they show three typical spectrum patterns.

Acousticmyogram Measured with Electrosimulation During Muscle Fatigue

JaLCDOI	10.18926/19663
フルテキストURL	Mem_Fac_Eng_OU_33_2_39.pdf
著者	Yanagi Makoto\| 岡久雄\|
抄録	The acousicmyogram (AMG) is a mechanical phenomenon recorded at the surface of an active muscle. It is used to monitor force production, fatigue, and contractile properties of muscle. In this study, the new electrode with accelerometer for electrostimulation and acoustic detection. It consists of Ag-AgCl active electrode and solid-gel annular groud, and a very light piezoresistive accelerometer. The recorded AMG waveform depends on the pulse amplitude and duration of stimulation current and its lag from the electroatimulation is about 7 ms. The strengh-duration (S-D) curve (the threshold current for stimulation vs. pulse duration) describes the excitability of muscle. The left forearm is electrostimulated by using the same electrode and the muscle vibration (AMG) is recorded with accelerometer. During the muscle fatigue, the S-D curve changes and the current threshold increases under the same pulse duration. The rheobase of S-D curve increases gradually but the chronaxie hardly changes during muscle fatigue.

A Numerical Study on the Performance of an Open-type Flat-plate Solar Collector

JaLCDOI	10.18926/19660
フルテキストURL	Mem_Fac_Eng_OU_33_2_25.pdf
著者	Song Baoyin\| 稲葉英男\| 堀部明彦\|
抄録	A set mathematical models was developed for predicting the performance of an open-type flat-plate solar collector, and solved numerically through an implicit difference method. The effects of various parameters on the absorption of solar energy for the collector were investigated. The results showed that the solar energy absorptance of the open-type flat-plate collector was relatively high especially for the region where the weather was humid and hot, and there were an optimum length and an optimum tilt angle for the absorbing plate on which the collector could obtain the highest solar energy absorptance. It was found that the latent heat flux of water evaporation could be 5 to 15 times larger than the sensible heat flux. The effects of the magnitude of the solar incident flux, the atmospheric humidity, the atmospheric temperature, the absorbing plate tilt angle, and water film thickness on the temperature rising of the water film were clarified in numerical quantities. The increase of the solar incident flux, the atmospheric humidity or the atmospheric temperature also resulted in a rise in the energy absorptance of the collector.

Small Type Hydrocyclone with a Perforated Inner Cylinder

JaLCDOI	10.18926/19657
フルテキストURL	Mem_Fac_Eng_OU_33_2_19.pdf
著者	山本恭二\| Jiao Xuecheng\| Jiao Xuezhen\|
抄録	A new type of hydrocyclone with a perforated inner cylinder is tested experimentally to study its performance for liquid-solid separation. The size of the cyclone is small so that it may be effective for small particle separation. Two types of the inner cylinder were made : the one has 39.5% void fraction of the perforated surface and the other has 73.5% . The mean particle diameter is 4.5 μ m. It is found that the pressure loss of the cyclone with the inner cylinder is reduced by about 25% compared with that of the ordinary type. The new type cyclone has better separation efficiency.

著者	山本恭二\|
抄録	The molecular dynamics study is applied for interaction of the gas molecule with the solid wall to analyse the flow of a rarefied gas between two wall. The wall consisting of Pt molecules is considered to be in a state of physical adsorbates. Two problems are considered : one is the flow problem and the other is the temperature problem. It is found that the tangential momentum accommodation coefficient is about 0.8 when the relative speed ratio of the two walls is unity, while it decreases with increasing Knudsen number when the relative wall speed ratio is 5.0. It shown that the temperature accommodation coefficient is about 0.85 at 300K wall, 0.75 at 450K wall, and 0.69 at 600K wall.
