Applications Definition and 662 Threads

An application program (app or application for short) is a computer program designed to carry out a specific task other than one relating to the operation of the computer itself, typically to be used by end-users. Examples of an application include a word processor and a media player. The collective noun refers to all applications collectively. The other principal classifications of software are system software, relating to the operation of the computer, and utility software ("utilities").
Applications may be bundled with the computer and its system software or published separately and may be coded as proprietary, open-source, or projects. Apps built for mobile platforms are called mobile apps.

    Laplace Transforms and its applications

    Hi, I am taking a circuits analysis course currently. We are studying Laplace Transforms. I was wondering if anybody out there knows a way of bypassing all of the cumbersome complex algebra to find the partial fraction decomposition of a given function with respect to s. If not maybe...

    Applications of Vast Amounts of Electricity?

    Out of curiosity, what would an extremely abundant source of electricity provide the ability to do? Obviously it's cost would go down, allowing much more to be done with it in the home, but I'm looking for things along the lines of electrolysis of water to cheaply produce hydrogen, etc. Also...

    Nonequilibrium Applications of Newton's Laws of Motion

    A 292 kg motor cycle is accelerating up along a ramp that is inclined 30.0 degrees above the horizontal. The propulsion force pushing the motorcycle up the ramp is 3150 N, and air resistance produces a force of 250 N that opposes the motion. Find the magnitude of the motorcycle's acceleration.
