Abstract

Reliable communication has become very crucial in the transmission applications. Hence, to design hardware to handle reliability is the most important part of communication. In this work, we propose a new secured ALU (Arithmetic and Logic Unit) against fault attacks that is used in ARM processor which can correct any 5-bit error in any position of 32-bit input registers of ALU. We also designed a BCH (Bose, Chaudhuri, and Hocquenghem) codec (encoder, decoder) using the prototyping FPGA. Further, in this thesis we designed (63, 36) the BCH encoding and decoding system to tolerate the 5-bit faults. The codec system and ALU system are based on using Verilog description language. Since...

Feet Motion Pattern Recognition Based on Data from Swiss Ranger Camera and other Dynamical Sensors with Offering an Intelligent Data Bank in Motion Correction and Rehabilitation

, M.Sc. Thesis Sharif University of Technology Sharifi Kolarijani, Arman (Author) ; Sayyaadi, Hassan (Supervisor)

Abstract

In this project, we use an off-line motion capture technique for walking pattern recognition and reconstruction, and apply a sensory data acquisition system for extracting knee and ankle joints angular movements. Our approach is a marker-based object tracking technique using only one camera and four markers as data acquisition system, and a neural network method is developed for marker detection. Different walking condition considered including: straight position, inclined position with 〖+5〗^° slope, and 〖-10〗^° slope. Using pattern obtained from above process, the BVH format of the motion is built for 3D reconstruction of the performer’s motion. Since the obtain data describe the motion of...

Capture, Processing and Transmitting Images From Downhole Camera

, M.Sc. Thesis Sharif University of Technology Saki, Mohammad (Author) ; Movahedian, Hamid (Supervisor)

Abstract

The goal of this project, has been designing a downhole camera, which captures images from environment of a well and transmits that to the surface. High temperature and pressure of well environment and corrosion and limitation in data transmission rate which is because of mono conductor cable, are the challenges of designing this system. For doing that, first, the principles of image compression are explained. Then, based on that, an image compression system based on wavelet transform has been designed. Its components are examined too. For making the introduced system resistant to the high pressure and temperature, using an isolated case is suggested. For implementation, an...
