A video-rate optical holographic display is achieved by using an azo-dye-doped liquid crystal as the passive, updatable recording material. The response time of this material is measured in the order of several to tens of milliseconds, depending on recording beam intensities, polarization directions, and polarization states. A holographic video at a refresh rate of 25 Hz, sourced from a spatial light...
We verified the variance of Wnt signaling pathway among different subtypes of breast cancer. Gene expression profile data of breast cancer (series number GSE19536) were obtained from Gene Expression Omnibus (GEO) database of National Center for Biotechnology Information (NCBI). Breast cancer samples were served as study materials. Gene expression data of Wnt signaling pathways were analyzed by variance...
This paper presents a unified modeling and solving approach for multiphysics topology optimization. A multiphysics continuum field is usually controlled by certain partial differential equations (PDE). Based on the general form of the PDE, this paper presents the mathematical model of the multi-objective multiphysics topology optimization, derives the unified solving scheme of the PDE, gets the sensitivities...
M-Learning has been practiced for decades with success research results in various fields and levels. In order to enhance the quality of instructional activities in terms of students¡¦ learning motivation, human association, as well as the linkage between the students and the learning context and materials, instructional pervasive gaming (IPG) is integrated as the approach. This paper draws a learning...
This study aimed at exploring whether the web 2.0-based note-sharing cooperative learning method worked more effectively than classroom cooperative learning with Student's Team Achievement Division (STAD) method and the traditional lectures in teaching Chinese rhetoric comprehension. The variables examined were students' achievement and learning motivations on Chinese rhetoric comprehension. The web...
It is necessary to analyze the demand for emergency materials before establishing a regional reserve system of emergency materials. In this paper, emergency materials are classified according to its use value and characteristics. The reasoning framework of the analysis of demand for emergency materials is constructed. The assessment method of emergent events is discussed by using fuzzy evidence theory,...
Emergency material storage should ensure the supply of goods when rescue operations are underway, at the same time take the economy of storage into consideration. For a class of location and layout problems of emergency material storage, a mathematical model was established based on integer programming. Considering the security of emergency material supply as constraints, the minimum of reserve costs...
At home and abroad, there are usually two types of solar receivers. One is the tracking-sun type and the other is nontracking type. The economic indicators we use to evaluate the solar receivers are the expense of the structure of the devices, the photovoltaic conversion rate, the expense of the routine operation and maintenance, and the utility of energy and materials. Analyzing the economic indicators...
