With the advancements of mobile communication technologies, the utilization of audio-visual information in addition to textual information becomes more prevalent than the past. Cryptographic approaches are therefore necessary for secure multimedia content storage and distribution over open networks such as the Internet.
This thesis presents the design and development of several novel small and wideband patch antennas. Microstrip antennas have the attractive features of low profile and light weight. However the antennas may be too large for practical applications at the lower microwave frequency
In this work, 28GHz microstrip patch array antennas are studied. Designs of broadside pattern microstrip antenna arrays on Duroid are presented. First, an 8-element linear array is designed and its measured resonant frequency is 27.95GHz, which deviates 0.5% from the simulation. Broadside
This report covers a master thesis in embedded systems, the goal of which was to investigate the high speed data collection capabilities with a Blackfin DSP. Basic theory about sampling and noise is covered briefly from a practical point of view. The
Existing VoD solutions often rely on unicast to distribute content, which leads to a higher load on the VoD server as more nodes become interested in the content. In such case, P2P is an alternative way of distributing content since it makes
There are many diļ¬erent applications where three dimensional data describing the shape of an object is needed. For example it is used in the wood industry to determine the optimal sawing of logs; in the electronics industry to examine solder paste deposits
In recent years there was a notable developmental leap in communications systems operating at microwave frequencies. In the dissertation, the goal is to demonstrate the challenges and to propose solutions that enable the successful design and realization of very wide band microwave
Because of technological advancement, transistor dimensions are approaching the length scale of the electron Fermi wavelength, on the order of only nanometers. In this regime, quantum mechanical phenomena will dominate electron transport. Using InAs single quantum wells, we have fabricated Y-shaped electron…
A key platform technology for InP optical waveguide MEMS is developed. The novel waveguide design is entirely released from the substrate by sacrificial etching and the suspended waveguide is supported by lateral tethers. This allows free-standing, movable segments of waveguide while preventing
There is a lot of applications for DSPs (Digital Signal Processor) in the most rapidly growing areas in the industry right now as wireless communication along with audio and video products are getting more and more popular. In this report, a DSP,
