Design and Construction of an Artificial Thumb Controlled by Command from the Index Finger
, M.Sc. Thesis Sharif University of Technology ; Salak Ghafari, Ali (Supervisor)
Abstract
This study provides preliminary work on the development of manual rehabilitation device for wearable and robotic manual applications. This work examines the motion of the fingers using the sensors. The developed mechanism is based on a combination of strain gauge sensors and a stepper motor, which forms the motion of the artificial thumb. In this thesis, the creation of an artificial thumb has been done with one degree of freedom, the movement and grabbing of lightweight objects. For grabbing objects, the command of controlling and keeping objects is performed through the IAR software and labVIEW software which is given to the stepper motor.This study describes the details of the work done...

Abstract
To extend a procedure to ensure the safe operation of a water reactor, we develop a numerical method to compute the high frequency pressure spikes of water hammer with liquid column separation in pipes. In this regard, we first extend a finite-volume all-speed method to solve the full one-dimensional Navier-Stokes equations. This method is capable of simulating gas and liquid phases as well as the vapor-liquid one. On the other hand, the current extended method should be capable of capturing high frequency pressure spikes, which are formed due to water hammer and column separation in pipes. The existence of such high frequency spikes has been recently reported experimentally by other...
