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

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

They were originally designed to machine metals; however‚ with the advent of plastics and other materials‚ and with their inherent versatility‚ they are used in a wide range of applications‚ and a broad range of materials. In machining jargon‚ where the larger context is already understood‚ they are usually simply called lathes‚ or else referred to by more-specific subtype names (toolroom lathe‚ turret lathe‚ etc.). These rigid machine tools remove material from a rotating workpiece

Sewing Machine Needles by W. A. Wimalaweera Introduction We know that the needle is a main element in the sewing machine. Earlier people used tiny pieces of material for sewing. Initially they were made from hones or bones of animals. In this session we will follow the gradual improvement of the needle. According to the type of material‚ there are different types of needles available. How ever the structural parts of a needle is common to all types. Needles are available in a wide range of sizes

EE 2403 SPECIAL ELECTRICAL MACHINES 2 MARKS UNIT-I - SYNCHRONOUS RELUCTANCE MOTOR 1. What is synchronous reluctance motor? A reluctance motor is a type of synchronous electric motor which induces non-permanent magnetic poles on the ferromagnetic rotor. Torque is generated through the phenomenon of magnetic reluctance. 2. Define the characteristics of synchronous reluctance motor. The synchronous reluctance motor is not self starting without the squirrel cage. During run up it behaves as an induction

Can a machine be a person? The topic of this debate is whether machines with artificial intelligence that is able to replicate human behavior can be considered human or not. This house believes that computers are fully capable of being humans because regardless of whether it is made of the ‘wrong stuff’ if it is able to adapt to human attributes or behavior then there should be no reason to classify them as otherwise. This argument is considered from a materialist view; which states that we

and dystopian novels and movies. These stories provide a wide array of opinions about the role of machines in life. Certain authors‚ such as Bellamy‚ would argue advancements and use of machinery is necessary to push society to a better‚ brighter future. However‚ reading Forster’s The Machine Stops makes one question the influence of machinery in our lives. Technology‚ like most things in life‚ can be considered both enslaving and liberating. In the 21st century it has allowed individuals to
