NCERT Class 7 Chapter 1 - Integers

 This tutorial discusses NCERT Class 7 Chapter 1 - Integers. We cover the following topics:

  • Number line
  • How to perform  + - x and ÷ operations with integers 
  • BODMAS (Not in your book)
  • Properties of operations on Integers
    • Closure under + - x and ÷
    • Identity  under + - x and ÷
    • Commutative property of  + - x and ÷
    • Associative Property of + - x and ÷
    • Distributive Property of + - x and ÷

Discrete Wavelet Transform

Code and sample files for this demo can be downloaded from here . Code uses only libraries from the ACV-VirtualMachine.No extra libraries are needed. You can unzip the code to any folder on your system. All paths used in the code are relative. We are using the folder "~/acv/code/dwt_demo/" Compiling and running the code is fairly straight forward. You only need to run the following two commands: acv@acv-vm : ~/acv/code/dwt_demo/bin $ cmake ../src/wavelet_demo_others/ -- The C compiler identification is GNU 7.5.0 -- The CXX compiler identification is GNU 7.5.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - ...

Testing image capture with high speed cameras

Image
In industrial systems, objects may be moving along conveyor belts or carried on pick and place machines. A camera based inspection solution for such situations needs to take into accoun that the object in question may not be stationery, or at a fixed distance from the camera. Ergo, the captured image may not contain the object in focus, or not have the object in view at all. One option would be to stop the conveyor belt to take a photo of the object:   However, stopping a conveyor belt is not always possible. You would need cameras that can capture a clear image even when objects are moving. Enthusiasts naiively assume that one can take a video and perform analysis on individual frames of the video. Unless the video has the correct frame rate and good resolution, the solution would not work. Assume that you need to implement an industrial imaging solution to monitor items moving on a conveyor belt. You should consider specifications such as these: Distance from camera t...
