Absolute scaling law for temperature data in Rayleigh-Benard convection

In addition to the hierarchical-structure (H-S) model,this paper further explores the most intensive intermittent structure of Rayleigh-Bénard convection at the high Ra numbers proportional to temperature.With respect to the discovery and by means of the scale,both of Bolgiano,there are two regions of the structure holding the absolute scaling law given by Ching's paper.Through theoretic analysis of data,this paper indicates that the regions act as two local intensive intermittent structures,by which the st...     

推帚式TDI-CCD相机应用分析

简要介绍了推帚式TDI-CCD相机及TDI-CCD像感器的工作原理，对引起相机调制传递函数退化的几个因素进行了详细分析，这些因素包括几何尺寸、电荷转移损失、速度失配、电荷分立运动，而且对离散空间域的线阵静态扫描MTF进行了分析研究，阐述了TDI-CCD级数与速度同步性、信噪比、动态范围的关系。     

A Complete Set of Addition Laws for Twisted Jacobi Intersection Curves

A complete system of addition laws on an elliptic curve E is a collection of addition laws with the property that for any pair of points P1,P2 on E at least one of the addition laws in the collection can be used to compute P1+P2.This paper proposes a complete set of the addition laws for arbitrary twisted Jacobi intersection curve.
