Distributed temperature sensing with neodymium-doped optical fiber

Creator:: Lounsbury, Jimson S.
Abstract:: Polymer electrolyte membrane (PEM) fuel cells are being studied for use as high efficiency power plants in alternative fuel vehicles. To maintain high efficiency the operating temperatures of the membranes in these fuel cells must be closely monitored and controlled. However, the environment inside of the fuel cell is not...

Investigation of bipolar resistive switching in zinc-tin-oxide for resistive random access memory

Creator:: Murali, Santosh
Abstract:: Resistive random access memory (RRAM) is a non-volatile memory technology based on resistive switching in a dielectric or semiconductor sandwiched between two different metals. Also known as memristors, these devices are potential candidates for a next-generation replacement for flash memory. In this thesis, bipolar resistive switching is reported for the...

Development of adaptive damping power take-off control for a three-body wave energy converter with numerical modeling and validation

Creator:: Zhang, Zhe
Abstract:: The performance of the power take-off (PTO) system for a wave energy converter (WEC) depends largely on its control algorithm. This paper presents an adaptive damping control algorithm that improves power capture across a range of sea states. Validation for the numerical model was performed using data from two sources;...

Applied color processing

Creator:: Zhang, Heng
Abstract:: The quality of a digital image pipeline relies greatly on its color reproduction which should at a minimum handle the color constancy, and the final judgment of the excellence of the pipeline is made through subjective observations by humans. This dissertation addresses a few topics surrounding the color processing of...

Optimal communications system design for array-based electric generation

Creator:: Orozco, Ricardo
Abstract:: The world's demand for energy is an ongoing challenge, which has yet to be overcome. The efforts to find clean energy alternatives to fossil fuels have been hampered by the lack of investment in technology and research. Among these clean energy alternatives are ocean waves and wind. Wind power is...

Power-efficient two-step pipelined analog-to-digital conversion

Creator:: Lee, Ho-Young
Abstract:: Hand-held devices are among the most successful consumer electronics in modern society. Behind these successful devices, lies a key analog design technique that involves high-performance analog-to-digital conversion combined with very low power consumption. This dissertation presents two different approaches to achieving high power efficiency from a two-step pipelined architecture, which...

A Personal Dead Reckoning RFID Waypoint Updated System for Footstep Level Resolution Path Tracking to Enable Research Into Early Diagnosis of Alzheimer’s

Creator:: Connell, Sean Robert
Abstract:: The problem of footstep level resolution indoor path tracking and gait velocity lacks a good solution. The current solutions are either prohibitively expensive [4], extremely invasive to deploy [1], or too inaccurate to achieve the sub meter level resolution required to track foot paths. By combining existing pedestrian dead reckoning...

Enhancing macrocell downlink performance through femtocell user cooperation

Creator:: Zaid, Adem Mabruk
Abstract:: This thesis studies cooperative techniques that rely on femtocell user diversity to improve the downlink communication quality of macrocell users. We analytically analyze and evaluate the achievable performance of these techniques in the downlink of Rayleigh fading channels. We provide an approximation of both the bit-error rate (BER) and the...

Highly digital power efficient techniques for serial links

Creator:: Inti, Rajesh
Abstract:: Low power, high speed serial transceivers are employed in a wide range of applications ranging from chip-to-chip, backplane, and optical interconnects. Apart from being capable of handling a wide range of data rates, the transceivers should have low power consumption (mW/Gbps) and be fully integrated. This work discusses enabling techniques...

A digital multiplying delay locked loop for high frequency clock generation

Creator:: Uttarwar, Tushar
Abstract:: As Moore’s Law continues to give rise to ever shrinking channel lengths, circuits are becoming more digital and ever increasingly faster. Generating high frequency clocks in such scaled processes is becoming a tough challenge. Digital phase locked loops (DPLLs) are being explored as an alternative to conventional analog PLLs but...
