The desired results for micromorphic continuum mechanics and couple stress theory are naturally obtained via direct transitions and reductions from the coupled conservation law of energy for micropolar continuum theory, respectively. The basic balance laws and equations for micromorphic continuum mechanics and couple stress theory are constituted by combining these results derived here and the traditional conservation laws and equations of mass and microinertia and the entropy inequality. The incomplete degrees of the former related continuum theories are clarified. Finally, some special cases are conveniently derived.展开更多

Basic views of theories of system dynamics distinctively show its dialectical characteristics. More attention should be paid to the features of complicated nonlinear systems. The model simulation of system dynamics is a kind of structure-function simulation. One of the remarkable advantages of system dynamics is that it can handle problems of high order, nonlinear and multiplefeedback system.展开更多

The thermal model can accurately estimate the device temperature, which is linearly with electrical input power. The simulation results show that there is almost no temperature gradient within the OLED device working under steady state conditions. Furthermore, thermal analysis simulation results show that the surface properties （convective heat transfer coetficient and surface emissivity） of the substrate or cathode can significantly affect the temperature distribution of the OLED.展开更多

Four simultaneous basic equations, i. e., equation of interest rate and amount of circulating fond, equations of purchasing and selling of share, equation of changing rate of share price, and equation of interest rate, share price and its changing rate, have been established. Discussions mainly on the solution and its simple applications of the equation of interest rate and amount of circulating fond are given. The discussions also involve the proof of tending to the equilibrium state of network of stock market based on the time discrete form of the equation by using Banach theorem of contraction mapping, and the influence of amount of circulating fond with exponential attenuation due to the decreasing of banking interest rate.Keyworks: stock market; network model; differential equation; contraction mapping; elasticity; methodology展开更多

The zeroth law is represented by some parameters () that specify respective quantum states. The parameters are the elements of thermodynamic state space. The introduction of such parameters is based on a probabilistic nature of quantum theory. A quantum analog of the first law can be established by utilizing these parameters. The notion of heat in quantum systems is clarified from the probabilistic point of view in quantum theory. The representation of the second law can be naturally described in terms of these parameters introduced for the respective quantum systems. In obtaining the representation of quantum thermodynamics, consistency between quantum theory and classical thermodynamics should have been preserved throughout our formulation of quantum thermodynamics. After establishing the representation of the second law, the third law is discussed briefly. The relationship between thermodynamic temperatures and the parameters in is also discussed.展开更多

From an epistemological point of view, this indeterminacy leads back to the complex considerations involved in establishing a basic concept of education. In this article, the author explores in a preliminary fashion the possibility of identifying the essence of education in its performativity as an occurrence in context that always precedes and supersedes our theoretical considerations of it. Education is not to be understood primarily as something conceptual （theory） but rather in terms of its significance as a situational event （reality）. Educational reality thus informs educational theory and this relationship implies a knowledge-ethical surplus of the former as an inexhaustible source for the latter.展开更多

Domestic scholars generally call their theory incomplete contract theory or incomplete contract theory, because the theory is ba^ed on the following analytical framework： They use the incompleteness of contracts for research as starting point to property or （ residual ） optimal control with Ge for research purposes. It is the most important analytical tool for analyze business theory and corporate governance structures with Ge control incentives to obtain the information. GHM model directly inherit the transaction cost theory by Coase, and Williamson, and it is a critical development. Among them, the 1986 model is mainly to solve the integration problem of assets, in 1990, the model evolved into a general model of asset ownership.展开更多
