Audio Processing can be done in two ways, one is analog and the other one is digital. The most preferential way now days is Digital Audio Processing because analog signals are a representation of data streams that are variable in time whereas digital stream is a representation of the same data in discrete points(samples). More samples we have more accurate our data is.
Quiz Projects
You can build general knowledge (gk ) quiz application. It will have two interfaces, one for the user who takes the test and another one for the administrator who can create, edit, update or delete the test. Moreover, it will have two other modules, one for calculating the marks of the user and others for reporting it.
This project can be built in any language but if you want to learn programming skills, you should build this software in C, C++ or Java. High-level languages such as VB or .NET.If you want it to build quickly you should use ruby on rails.
For the database, you can use MySQL. It is open-source and available for free.
My personal favorite method is to use CMS( Wordpress, Joomla or Drupal).
In this post, I will discuss the WordPress method with you and it will not take the only a couple of hours for your own professional quiz management system. It is five step procedure:
Step 1) Install xampp (for Linux and Windows) or MAMP for Mac
Step 2) Open PHPMyAdmin from admin panel of your first step installation server
Step 3) Create database quiz
Step 4) Download and Install Wordpress CMS. Installation requires details of your database name, username, and password. Write database name as "quiz", username as "root" and password are given at the installation time.
Step 5) Install the WP-Pro-quiz plugin and you are done.
If you have any questions regarding its installation, please let me know using the comment box given below. I would be happy to oblige.
I am posting you a few projects from SourceForge which will help you to understand these type of projects :
1.Quiz
2.Pro Quiz
3.Open Mobi Quiz for Mobile
4.Open QB: Exam maker for teachers
Hydraulics project ideas
Hydraulics is a science which deals with mechanical properties of the liquid. It is basically a liquid form of pneumatics. In pneumatics, we use compressed air and in hydraulics, we use the compressed liquid. When we compress the liquid, it gets pressurized and It uses the power of pressurized liquid for doing various tasks. It works on the principle of Pascal Law which states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.
You can find hydraulic machines from your backyard to a big construction site.
Concept:
It works on a very simple concept that when the force applied to incompressible liquid at one point, it gets transmitted and multiplied at another point. The multiplication factor of this force depends upon the area of the piston.
Industrial engineering projects
Industrial engineering is a branch of engineering dealing with the optimization of complex processes or systems. You can do various kinds of projects in this branch especially related to robotics. In this post, we will discuss some other projects done by previous students at various universities around the world.
