matlab频谱三维图，时间频率幅值。频谱分析三维图，计算机绘制的三维频谱以频率为横坐标，以振幅为纵坐标，以时间为斜轴，在视觉上是一种立体频谱。(Matlab three dimensional spectrum diagram, time frequency amplitude. Spectrum analysis of three-dimensional map, 3D computer generated by frequency spectrum as the abscissa, the amplitude of the vertical axis, in time for the inclined shaft, the vision is a kind of three dimensional spectrum.)

ransac程序，在他人的基础上改进，增进了速度，经过测试，可直接应用于遥感影像匹配去除误差较大点，希望对大家有用。(ransac program, others based on improvements and increased speed tested, can be directly applied to the remote sensing image matching remove errors larger point, and hope to be useful.)

After we calculate the R peaks of the ecg signal, we identify different criteria : a) Heart rate. b) Regularity of the R-R peaks (Look at the R-R distances). 1. Regular (are they equidistant apart). 2. Irregular. c) Rhythm 1. Tachycardia ==> Fast. 2. Bradychardia ==> Slow. 3. Normal.

An inductive feedback technique increases the speed of resonant circuits by 62 , allowing operation near the of transistors. The technique leads to a fundamental oscillator operating at 128 GHz with a power dissipation of 9 mW and a phase noise of 105 dBc/Hz at 10-MHz offset. A divide-by-two circuit based on the idea and incorporating a sampling mixer achieves a maximum speed of 125 GHz while consuming 10.5 mW. The prototypes have been fabricated in 90-nm CMOS technology.(An inductive feedback technique increases the speed of resonant circuits by 62 , allowing operation near the of transistors.
