Electrical Machines I Prof. Krishna Vasudevan‚ Prof. G. Sridhara Rao‚ Prof. P. Sasidhara Rao 2 Basic Principles As mentioned earlier the transformer is a static device working on the principle of Faraday’s law of induction. Faraday’s law states that a voltage appears across the terminals of an electric coil when the flux linkages associated with the same changes. This emf is proportional to the rate of change of flux linkages. Putting mathematically‚ e= dψ dt (1) Where‚ e is the induced

technological aspects will be presented as follow: Economic factor a) Firstly‚ the demand for sewing machines in the western hemisphere had been declining for more than two decades. Industry profitability had deteriorated‚ particularly hard on manufacturers of industrial machines and low-price mechanical machines for domestic use. b) Second‚ the sharp drop in demand for industrial sewing machines has result much more fierce competition on the professional side in Europe and in the US.

and scientists use scientific knowledge to design and build machines that make our lives easier. The machines they build today started off with the basics‚ which are known as Simple Machines. Simple Machines are defined as the simplest mechanisms that use mechanical advantage to multiply force. These machines have either few or no moving parts‚ and use energy to work. This term is usually referred to the six classical simple machines; lever‚ wheel and axle‚ pulley‚ inclined plane‚ a wedge and

Can Machines Think ? This paper regards several points of view on the subject of‚ what is commonly referred to as Artificial Intelligence‚ or AI. AI is the attempt to make machines‚ specifically computers‚ perform intelligently through programming. Already‚ this definition has a problem in that the word intelligence can have many interpretations. This essay will attempt to put forward some ideas for how to approach this problem. It could be said that the human brain is nothing more than a machine

In The Time Machine‚ by H.G. Wells‚ probably the biggest moment in the book is when the Time Traveller realizes how much the human race has evolved over the many years he has gone through. The people he sees now are nothing like what he is used to seeing before. The difference between the morlocks and the eloi is quite distinct. The two races of humans may seem very different but they are actually mirror images of each other. Everything from appearance‚ traits‚ and even diets are completely different

The Physics of an MRI Machine. Whitney Wright PH106/006 Dr. Probst 06/05/2012 The Physics of an MRI Machine There are many physical concepts used in a Magnetic Resonance Imaging‚ also known as MRI‚ machine. There are many physical concepts used when an MRI is taken of the body‚ such as; radio waves‚ resonance and pulse sequences‚ magnetic fields being produced and lastly‚ magnets. Radio waves much stronger than the magnetic field of the Earth are sent through
