1、培训课件协助营运主管对终端人员客户店长导购开展培训工作提升终端运营管理水平Modelling, simulation, and visualisation together create the third branch of human knowledge on equal footing with theory and experiment. Model-Driven Development (MDD) has been proposed as a means to support the software development process through the use of a

2、model-centric approach. The objective of this paper is to address the design of an architecture for scientific application that may execute as multithreaded computations, as well as implementations of the related shared data structures.

Reflection high-energy electron diffraction (RHEED) is an important in situ analysis technique, which is capable of giving quantitative information about the growth process of thin films

7、and its control. The analysis of RHEED intensity oscillations has two purposes. One is to control the film growth, and the other is to understand the mechanism of the film growth using the MBE through the analysis of surface morphology as a function of time. Such control allows the development of st

Growth09 is a numerical model that uses multithreaded and partially nested transactions for simulation of epitaxial growth of thin films. Reasons for new version: Responding
