An automotive engine model for air-fuel ratio control using cylinder pressure information
(Texas A&M University, 1997)
Increasingly strict emission standards require very accurate and fast air-fuel ratio (AFR) control in combustion engines. This thesis addresses the design methodology currently used for synthesizing a control system for ...
A router agent for capacity assessment in packet video
(Texas A&M University, 1997)
Current videoconferencing applications operating on packet networks do not have the capability to gauge the available network capacity prior to requesting additional quality by subscribing to enhancement layers. To minimize ...
Software based low bit rate speech codec using the Discrete Wavelet Transform
(Texas A&M University, 1997)
Wavelets are being widely used in the area of signal compression and have given very good results but a lot of attention has been given to image compression and audio compression but not to speech compression in particular. ...
A reduced voltage polarization intensity electrooptic modulator in SBN:60 utilizing a step strain waveguide
(Texas A&M University, 1997)
Strain induced optical waveguides have been produced in LiNbo3 and SBN substrate material using a step strain geometry. Propagation losses in SBN as low as 1.43 dB/cm and 2.64 dB/cm were achieved for TE and TM polarizations, ...
Study of high frequency & low frequency electronic ballasts for HID lamps
(Texas A&M University, 1997)
High-intensity discharge (HID) lamp electronic ballasting is receiving increasing attention in the recent years as low wattage HID lighting systems are finding indoor applications. Advantages of high frequency electronic ...
Multicarrier CDMA using wavelets in multipath fading channel
(Texas A&M University, 1997)
A new multicarrier direct sequence spread spectrum code division multiple access (DS-SS-CDMA) is proposed. Due to the wide bandwidth characteristic of the DS-SS-CDMA signal, it is considered to undergo the frequency selective ...
Microstrip antenna couplers and active antenna amplifying arrays
(Texas A&M University, 1997)

Design of a fuzzy controller for energy management of a parallel hybrid electric vehicle
(Texas A&M University, 1997)
This thesis addresses the design of a control scheme based on Fuzzy Logic to minimize automobile fuel consumption and exhaust emissions while maximizing battery state of charge (SOC) for hybrid vehicles. The advantages the ...
Bridging faults in CMOS circuits which are non-Iddq testable and their effect on delay testing
(Texas A&M University, 1997)
Bridging defects which occur in CMOS complementary gates (rather than ratioed logic gates) are investigated. Realistic bridging defects are shown to exist which are non-Iddq testable, but which can be deterministically ...
Automated safety and training avionics for general aviation aircraft
(Texas A&M University, 1997)
The past decade has seen the U.S. general aviation community plagued by substantial cost increases while operating in an increasingly complex and crowded air traffic control structure. Unfortunately, there has been a ...
