matlab例程 distmesh
matlab有限元网格划分程序
DistMesh is a simple MATLAB code for generation of unstructured triangular and tetrahedral meshes. It was developed by Per-Olof Persson (now at UC Berkeley) and Gilbert Strang in the Department of Mathematics at MIT. A detailed ...
资料/手册 Trade and Heterogeneous Labor
We show in the context of a new economic geography model that when
labor is heterogenous trade liberalization may lead to industrial agglomeration
and inter-regional trade. Labor heterogeneity gives local monopoly
power to firms but also introduces variations in the quality of the job match.
Matches ...
手册 FLX-A301-A
The FlexiForce A301 is our smallest standard piezoresistive
force sensor.
书籍 The Mobile Multimedia Business
The first practical examples of mobile communications were used in many countries like
the USA, the UK and Germany in military services, and played a significant role in the
First World War to transfer important information from the front to headquarters to take
further actions. Good and secure wire ...

技术资料 使用反电动势滤波进行无传感器BLDC控制
简介本应用笔记说明了无传感器无刷直流（Brushless DC，BLDC）电机控制算法，该算法采用dsPIC数字信号控制器（digital signal controller，DSC）实现。该算法对电机每相的反电动势（back-Electromotive Force，back-EMF）进行数字滤波，并基于滤得的反电动势信号来决定何时对电机绕组换相。这种控制技术不需要使用离散式低 ...
