### Opencv-3.2.0 on Windows 10 - 64 bit Using Visual Studio 2015

Using the latest version OpenCV (currently opencv-3.2.0) pre-built for 64 bit Windows with Visual Studio 2015 is discussed. It is available to download at
https://sourceforge.net/projects/opencvlibrary/files/opencv-win/.
Then, the downloaded file, opencv-3.2.0-vc14.exe is extracted at C:\opencv as a folder called opencv320. Visual Studio 2015 IDE is downloaded from https://www.visualstudio.com/downloads/ and install. The following steps are tested on Windows 10 64 bit using Visual Studio 2015 and OpenCV-3.2.0. For other versions, the precedures are similar.

At first OPENCV_DIR is declared as an enviroment variable. Run 'Command window' in administrator mode by right clicking start menu and choosing command prompt (admin). Enter

setx -m OPENCV_DIR C:\opencv\opencv320\build\x64\vc14

### A LaTeX Report Template for Myanmar Language Using XeTeX

This is a template for LaTeX report in Myanmar language using XeLaTeX. It is available at

https://github.com/yan9a/LaTeX_Myanmar_Language.

To properly render Myanmar fonts using LaTeX, it is necessary to use TeX typesetting engines that support Unicode such as XeTeX. Simple examples for testing XeTex can be found in an older post Myanmar (Burmese) Language with XeTeX and LuaTeX.

### Integration of Accelerometers

We have several 3-axis accelerometers attached to a rigid body at arbitrary positions. The rigid body is moving at arbitrary linear and angular movements, but the accelerometers can only sense linear accelerations. Consequently, the information about angular movements of the rigid body is not available.

A question is whether it is possible to integrate them to get an equivalent accelerometer without using angular movement information.
After consideration, I think the answer for that question is 'YES'.
