Microfabricated Electrode Arrays Suitable for Stimulation and Recording in Cardiac Electrophysiological Studies
(2008-09-09)
Sudden cardiac arrest (SCA) caused by ventricular fibrillation is one of the most serious heart related problems in the United States today which is responsible for hundreds of thousands of deaths per year. The goal of ...
Channel Estimation and Equalization for Doubly-Selective Channels Using Basis Expansion Models
(2008-09-09)
The nature of the wireless channels places fundamental limitations on the performance of wireless communication systems. In addition to the frequency-selectivity characteristics caused by multipath propagation, the high-rate ...
Characterization of Lead-free Solders for Electronic Packaging
(2009-02-23)
The characterization of lead-free solders, especially after isothermal aging, is very important in order to accurately predict the reliability of solder joints. However, due to lack of experimental testing standards and ...
On-wafer S-parameter Measurement Using Four-port Technique and Intermodulation Linearity of RF CMOS
(2009-02-23)
Accurate on-wafer characterization of CMOS transistors at extremely high frequencies, e.g. above 60GHz, becomes critical for RFIC designs and CMOS technology development for millimeter wave applications. Traditional two-step ...
Simulation Based Power Estimation For Digital CMOS Technologies
(2009-02-23)
The estimation of power in digital CMOS circuits has become a significant problem, especially for present day semiconductor technologies. Finding a balance between opposing factors of estimation accuracy and computation ...
Statistical Analysis of Time Delays in USB Type Sensor Interfaces on Windows-based Low Cost Controllers
(2009-02-23)
Real-time control systems need sensor data at periodic and predictable time intervals- this is one aspect of what is commonly called ""determinism"". Common forces that present
challenges to determinism in Windows-based ...
Scheduling in WiMAX based wireless networks
(2009-02-23)
This thesis describes two transmission scheduling algorithms and a hybrid ARQ transmission
handling algorithm designed for WiMAX based wireless networks. WiMAX networks
are based on Orthogonal Frequency Division Multiple ...
A Hardware-Software Processor Architecture using Pipeline Stalls for Leakage Power Management
(2009-02-23)
In recent years, power consumption has become a critical design concern for many VLSI systems. Nowhere is this truer than for portable, battery-operated applications, where power consumption has perhaps superseded speed ...
An Evaluation System For Mechanical And Electrical Characterization Of MEMS Devices
(2009-02-23)
The evaluation of MEMS devices during the developmental phase prior to packaging is challenging. However, evaluating a MEMS device in die form can be useful, as its electrical and mechanical test results can provide useful ...
Neuro-Fuzzy System with Increased Accuracy Suitable for Hardware Implementation
(2009-02-23)
Fuzzy controllers are easy to design for complex control surfaces but produce rough control surfaces which might lead to unstable operation. On the other hand neural controllers are hard and complex to train but they produce ...
