Electron transfer and conductance quantum

The relationship between the quantum capacitance and the conductance quantum gives rise to a quantum mechanical equation that encompasses the theory of electron transfer rate proposed by Rudolph Marcus.

Energy Balance Assessment of Magnetic Materials as Theoretical Hint for Formulation of Interoperable Magnetic-Mechanical Equation

Theoretical review on magnetic energy conception is still crucial since the recent discourse emerged in various conceptual speculations that lead into inconsistency in mathematical expression. The coming study should direct its formula into an interoperable equation which enables a magnetic energy to be observed as a mechanical work. The forthcoming expression of magnetic energy should represent operation of mechanical work definitely, considering the usage of Permanent Magnet (PM) in numerous mechanical devices. This interoperable magnetic-mechanical equation would be formulated from energy balance principle applied in both magnetic boundary and mechanical boundary. The energy balance assessment would clarify the usage of magnetic energy during the action of mechanical work. A computational study would assist this observation to interpret some magnetic parameters such as flux density B, magnetic strength H, magnetic energy Emon a self-engineered device named Frequent Flux Collider which examines PMs to be attracted and repelled frequently. The research objectives are: 1) Presenting the technique for assessing the energy balance in PM; 2) Proposing an interoperable equation for bridging magnetic energy and mechanical work. In conclusion, the assessment has brought a theoretical hint to the development of interoperable magnetic-mechanical formula.

Study on Traffic Flow Model Considering the Interaction of Vehicles

In this paper, considering the influence of mixed traffic and overtaking on traffic flow, the formula of viscous resistance was put forth; a new Hydrodynamics model was established. Discrete analysis was carried out on the mechanical equation through the difference method, through which the change in the traffic flows parameters through time and space can be analyzed. Finally, the measured data simulation analysis results show that the new traffic flow model is of certain practical reference.

Stabality Analysis of Deep Roadway Based on Coupled Thermo-Hydro-Mechanical Behaviors

In order to research the stability of excavation in deep mines under high ground stress, high rock temperature and high karst hydraulic, the interaction of stress field, seepage field and temperature field are discussed through basic constitutive relation, seepage equation, thermometer equation and coupled thermo-hydro-mechanical equation. A numerical model was built to simulate the excavation of deep roadway. The result shows that the simulated ground stress based on three fields coupled is much closer to the field measured value and the change of stress and displacement caused by the excavation are limited which is about same as the later monitoring.

A Springback Compensation System Based on Springback Mechanics and Design Parameter Optimization

A new springback compensation system based on springback mechanics is developed. The cause of springback is the bending moment before springback. To compensate the tool shape, it is necessary to satisfy the springback mechanical equation which is expressed by curvature and bending moment. In this system, the bending moment before springback is designed considering the springback mechanical equation. Actually, the optimum bending moment distribution is designed by modifying the design parameters such as curvature and punch load in this system so that the metal sheet is deformed into the desired shape. In the modification process of the design parameters such as curvature and punch load, the sequential response surface method is used to optimize them. When the proposed method was applied to V-bending, it was found that it was effective because the convergence rate is great and not only the curvature but also the punch load can be obtained.
