Smart System or Structure What is a Smart Structure? A smart structure is a system containing multifunctional parts that can perform sensing‚ control‚ and actuation; it is a primitive analogue of a biological body. Smart materials are used to construct these smart structures which can perform both sensing and actuation functions. If truly smart‚ these intelligent systems can determine their present state‚ decide what is the optimum or more desirable state and carry out an appropriate

magnetometer box (4) stopwatch. THEORY EXPERIMENTAL PROCEDURE PRECAUTIONS 1. Experimental magnets should be placed at the same horizontal level of the magnetic needle of magnetometer. 2. The deflection of deflection magnetometer should always lie between 300 and 600. 3. Magnets and magnetic materials should be at safe distance from the experimental set up. 4. Parallax should be avoided while taking the deflection.

electric guitar Introduction An electric guitar is a stringed musical instrument played with fingers or a plectrum (pick). It consists of a body‚ a neck and a headstock to which usually six steel strings are attached. The magnetic pickups transform the vibrations of the steel strings into audio signals that are driven through an amplifier. Thus‚ the amplifier is also an essential part of the electric guitar. It was the need of amplified sound in musical instruments that

these forces are on the order of e-4 N and are fairly small. In real devices such as electric motors many steps are taken to make the force larger using many turns instead of a single wire‚ using the ferromagnetic properties of iron to increase the magnetic field. In the current balance unit the lower bar is fixed. The upper bar is balanced a few millimeters above the fixed one by adjusting the counterpoise. There is yet another adjusting weight that brings the location of the center of mass of the

The simulations were accomplished using Finite Difference Time Domain Simulator (FDTD Simulator) based on the Finite Difference Time Domain Method. FDTD Simulator is sophisticated simulator and can take a significant amount of time to learn the complex features and it can run on a variety of operating systems. The primary advantage of FDTD over other full-wave models is that‚ FDTD being a time domain method allows broadband analysis of the antenna by Gaussian pulse excitation. The antenna characteristics
