Phase Generation and Manipulation in CMOS Integrated Circuits
(2008-04-01)
In this thesis three circuits are presented that demonstrate the creation and manipulation of various phases over a large bandwidth. Many systems demand the interoperability of various circuit blocks over a large frequency ...
Low-Noise Mixing Circuits in CMOS Microwave Integrated Circuits
(2009-08-25)
In this thesis, three low-noise active mixing circuits are presented in CMOS technology. Mixers can be found at the front-end of almost every communication systems. However, despite many advantages the active mixers have, ...
Cooperative Diversity in Wireless Transmission: Multi-hop Amplify-and-Forward Relay Systems
(2009-08-14)
A multi-hop, amplify-and-forward (AF), cooperative diversity system with K relays
is studied. An accurate approximate expression for the symbol-error-rate (SER) is
derived for the multi-hop system. Also, a lower bound ...
Investigating the Feasibility of Asynchronous Design Methodologies in Large-scale Microprocessor Systems
(2007-12-20)
Microprocessor systems have been advancing at a phenomenal rate, with each new generation introducing improved fabrication processes and architectural innovations. Unfortunately, traditional fabrication techniques cannot ...
Device Deployment Strategies for Large-scale Wireless Sensor Networks
(2008-01-16)
Planning device deployment is a fundamental issue in implementing wireless sensor network (WSN) applications. This design practice determines types, numbers and locations of devices in order to build a powerful and effective ...
Experimental Validation of an Elastic Registration Algorithm for Ultrasound Images
(2007-10-29)
Ultrasound is a favorable tool for intra-operative surgical guidance due to its fast imaging speed and non-invasive nature. However, deformations of the anatomy caused by breathing, heartbeat, and movement of the patient ...
Novel robotic mechanisms for upper-limb rehabilitation and assessment
(2008-08-14)
Robotic rehabilitation and assessment of the human upper-limb following stroke is currently limited in part by the inability of robots to replicate natural motion. In particular, motion of the shoulder girdle is usually ...
Directional Cell Breathing - A Framework for Congestion Control and Load Balancing in Broadband Wireless Networks
(2009-04-27)
Despite the tremendous bandwidth increase in 3rd generation (3G) Broadband Wireless
Networks (BWNs) such as Universal Mobile Telecommunication System (UMTS),
maintaining the mobile users’ Quality of Service (QoS) ...
A high-speed Iterative Closest Point tracker on an FPGA platform
(2008-07-16)
The Iterative Closest Point (ICP) algorithm is one of the most commonly used range image processing methods. However, slow operational speeds and high input band-widths limit the use of ICP in high-speed real-time ...
Use of a Hill-Based Muscle Model in the Fast Orthogonal Search Method to Estimate Wrist Force and Upper Arm Physiological Parameters
(2008-10-30)
Modelling of human motion is used in a wide range of applications.
An important aspect of accurate representation of human movement is
the ability to customize models to account for individual
differences. The following ...
