[Special Effects] Itrac_Ver_1_3 DL : 0: Author: David Sedarsky Summary: MatLab GUI for interface tracking and edge velocity determination MATLAB Release: R14SP2 Required Products: Image Processing Toolbox Description: Itrac works on image pairs taken at times T1 and T2, and tracks the motion of features in the images selected using thresholding and edge detection. Two sample image pairs (LIF images of OH in a turbulent flame) are included in the archive. Some of the work that led me to develop Itrac is detailed here: http://www.opticsinfobase.org/abstract.cfm?URI=ol-31-7-906

[Special Effects] 1c DL : 0: We rigorously analyze the dispersion function and the curvature of the dispersion surface of a photonic crystal to explore the fundamental limit of its angular sensitivities. With insight gained from group theory, we ﬁ nd that symmetry induced degeneracy gives rise to a singular dispersion surface curvature and a nonvanishing group velocity simultaneously. Near such a singularity, high angular sensitivities can be achieved at low optical loss. This phenomenon exists generally in most common two-dimensional and three-dimensional photonic crystal lattices, although it occurs only for certain photonic bands as dictated by symmetry.

[Special Effects] Bouncing_Smiley_Face2 DL : 0: 用matlab写的一个模仿抛物线动作的动画。可以自己设定加速度、启示位置等数值。-The laws for rotation are probably wrong (I made them up actually), but that s not what this file is about. Shown here is a very simple code that creates a nice animation, which can be quickly edited to suit anyone s needs. The parameters are ball radius, gravity, initial velocity in the Y direction, initial velocity in the X direction, vertical speed conservation ( ), horizontal speed conservation ( ) and initial angular velocity. Please note that the ball may stop moving at different locations for different trials, even with the same input parameters. This is due to the slight randomization of the deformations of the ball and the ground, which could lead to the ball getting "stuck" to the ground at times and stopping there. This is normal and deliberate.
