Modeling And Performance Evaluation Of A Power Electronic-based Controlled Fuel Cell System
(Electrical Engineering, 2007-08-23)
In fuel cell applications, design of an appropriate controller and selection of an Ultra-Capacitor require a suitable model of fuel-cell-systems that can adequately represent the significant characteristics of the system. ...
3D Interconnects For Die And Wafer Stacks
(Electrical Engineering, 2007-08-23)
3D integration results from the ever demanding trend towards smaller and lower-profile, lighter and lower cost packaged devices requires further package miniaturization. With the present System-on-chip (SOC) technology ...
Modeling And Characterization Of A Fabry Perot Pressure Sensor
(Electrical Engineering, 2007-08-23)
Fabry-Perot interferometers (FPIs) have been used as sensing elements for pressure transducers in many applications. Most of the current FPI pressure sensors measure amplitude changes of the reflected signals from a ...
Mitigation Of Window Effects In Inverse Synthetic Aperture Radar (ISAR) Imagery Using Multi-resolution Technique
(Electrical Engineering, 2007-08-23)
A method using Multi-Resolution technique for window effect mitigation in ISAR imagery, which occurs due to finite extent data, is presented in this work. Proposed method is supported with quantitative measure using both ...
Optimization Of H.264 High Profile Decoder For Pentium 4 Processor
(Electrical Engineering, 2007-08-23)
H.264 is an emerging video coding standard, which aims at compressing high-quality video content at low-bit rates. While the basic idea behind the encoding and decoding process still remains the same as in the previous ...
Multiplexing H.264 Video With AAC Audio Bit Streams, Demultiplexing And Achieving Lip Synchronization During Playback
(Electrical Engineering, 2007-08-23)
H.264, MPEG-4 part-10 or AVC [5], is the latest digital video codec standard which has proven to be superior than any early standards in terms of compression ratio, quality, bit rates and error resilience. However, the ...
Phase Locked Loop For Radiation Hardened Environment
(Electrical Engineering, 2007-08-23)
This thesis describes a Phase Locked Loop (PLL) design for operation within a radiation environment. Specific design architecture and techniques were implemented to help mitigate radiation effects that degrade PLL performance. ...
Localization Algorithms For Passive Targets In Radar Networks
(Electrical Engineering, 2007-08-23)
In this study, we propose an improved, robust algorithm for passive targets in radar networks. The main objective of this work is to improve the localization accuracy of the algorithm based on signal properties in combination ...
Feasibility Study Of Options For Aging Hydro-power Generation Facility
(Electrical Engineering, 2007-08-23)
Most of the hydro generation facilities are operating under derated capacity due to various factors. The availability of generation facilities is decreasing, the cost for maintenance is going up and plants are crippled ...
Improving the Quality of Low Bitrate LPC Speech Codec Using Gamma-chirp Filterbank
(Electrical Engineering, 2007-08-23)
In this thesis, two methods for getting higher speech quality in low bit-rate LPC coder in comparison with the original LPC coder were presented. In order to improve the quality of the speech, the embedded method which can ...
