Observation of true rotation has been relatively rare in living systems, but there may be many molecular machines that rotate. Molecular rotations accompanying function can be imaged in real time under an optical microscope by attaching to the protein machine either a small tag such as a single fluorophore or a tag that is huge compared with the size of the protein. As an example of the former ...

A specific absorption rate (SAR) measurements system has been developed for compliance testing of personal mobile phone in a brain phantom material contained in a Perspex box. The volume of the box has been chosen corresponding to the volume of a small rat and illuminated by a 3G mobile phone frequency (1718.5 MHz), and the emitted radiation directed toward brain phantom .The induced fields in ...

As, the number of vehicles are increased day by day in rapid manner. It causes the problem of traffic congestion, pollution (noise and air). To overcome this problem A FPGA based parking system has been proposed. In this paper, parking system is implemented using Finite State Machine modelling. The system has two main modules i.e. identification module and slot checking module. Identification m...

A linear electrostatic stepper motor has been designed and fabricated in a single mask surface micromachining process.. It consists of two drive units that alternately generate a step to move the shuttle. The friction and adhesion in the clamps has been measured. A friction coefficient of 0.8 * 0.3 have been found. The adhesion in the clamp is just low enough to release the clamping shoe. Stepp...

FDM is an AM method that currently being developed due to the flexibility of object geometry can be formed. This study aims design frame and drive XZ Head type engine. Stress simulation was carried out determine safety factor in frameXZ design. Lead screw parameters form torque, shear stress, axial critical load were calculated torque requirement driving motor. The value linear axis stepper mot...
