IV-VI semiconductor structures for laser fabrication of silicon.
(1998)
This dissertation describes experiments undertaken to develop techniques required to develop IV-VI lasers grown on silicon. A review of the IV-VI materials system, diode laser structures, recent IV-VI laser results, epitaxial ...
LOW-COST, SOFTWARE DEFINED FMCW RADAR FOR OBSERVATIONS OF DRONES
(2017-05-12)
This thesis focuses on implementing a small, low-cost, Frequency-Modulated-Continuous-Wave (FMCW) radar sensor using Software-Defined Radio (SDR) platforms. Extensive investigation and comparisons of existing SDRs are ...
Adaptive Distributed Source Coding Based on Bayesian Inference
(2015-08-14)
Distributed Source Coding (DSC) is an important topic for both in information theory and communication. DSC utilizes the correlations among the sources to compress data, and it has the advantages of being simple and easy ...
Analog free-space optical links.
(2005)
Free-space optics (FSO) communications is a technology that uses modulated infrared optical beams to transmit information line-of-sight through the atmosphere. There has been a substantial increase in the use of FSO ...
Ruggedized Feeding Techniques for Placement Insensitive Antennas
(2018-08-02)
Today's warfighter relies on extensive wireless technology to stay connected to allied forces and the battle theater. Communication equipment, IFF (identification friend-or-foe) identifiers, global positioning systems, ...
Performance evaluation of the third generation TD-SCDMA system.
(2004)
Firstly, a basic reverse TD-SCDMA system is setup, including a transmitter, a receiver and a channel. Within the receiver model, a specific soft Viterbi decoding algorithm is developed. Secondly, the system synchronization ...
PRACTICAL COUGH DETECTION IN PRESENCE OF BACKGROUND NOISE AND PRELIMINARY DIFFERENTIAL DIAGNOSIS FROM COUGH SOUND USING ARTIFICIAL INTELLIGENCE
(2020-05-07)
Cough is one of the most common symptoms for many of the diseases. Physicians have been using characteristics of cough for preliminary diagnosis of certain respiratory diseases for ages. But the methods have been subjective ...
Performance enhancement of large scale networks with heterogeneous traffic.
(2006)
Finally, these findings are applied towards improving the performance of the Differentiated Services architecture by developing a new Refined Assured Forwarding framework where heterogeneous traffic flows share the same ...
Molecular beam epitaxial growth and characterization of europium-doped calcium fluoride and fabrication of visible electroluminescent devices on silicon.
(1998)
An indirect band-gap precludes the possibility of efficient luminescence from Si. The widespread use of Si in electronics and rapid advances in Si device processing and design justifies the search for Si-based light emitters ...
