A performance comparison of three advanced edge detection algorithms, 2002

 Item — Call number MU Thesis Kea
Identifier: b2088044
Abstract Imaging systems that operate in the mid-infrared spectrum have a lot of potential for use in military trackers and weapon systems. Edge detection is the primary means from which a target's spatial and trajectory features are derived. Targets are separated from the image background using edge detection in a process called segmentation. Typical edge detection techniques employ thresholding operators to emphasize the areas in an image where intensity changes significantly. Techniques have...

A series-fed traveling-wave microstrip patch antenna, 1997

 Item — Call number MU Thesis Huy
Identifier: b2087884
Abstract This paper presents the design technique for a series-fed traveling-wave microstrip patch antenna array. The unique feature of this design is the employment of a notched feed patch as a radiating termination patch in combination with varying widths of radiating elements. This technique produces a low sidelobe performance. To achieve this effect, the antenna array is horizontally polarized, with measured results of -30 dB sidelobe, 4.5 degree 3-dB beamwidth, and 12 dBi gain at 39...

Designing a personal communication system for the city of Pune, India, 1998

 Item — Call number MU Thesis Doi
Identifier: b2087783
Abstract A Personal Communication System (PCS) is designed for the city of Pune, India using the Global System for Mobile Communication (GSM) standard. Even though Wireless Communication is a vast area for study, the important aspects of PCS system design are covered. While designing the PCS system, study of the geographic area, and the atmospheric and climatic conditions is very important. Pune has a very good atmosphere throughout the year. The Monsoon (rainy season) is moderate and will...

Interference mitigation for portable CDMA cellular radios, 1998

 Item — Call number MU Thesis Fok
Identifier: b2087984
Abstract Ideally, wireless handset users should be able to use their handsets to communicate anywhere within the designated service areas without fear of dropping call. In reality however, calls do get dropped and are getting increasingly more so from strong radio frequency (RF) interference due to heavy deployment of cellular systems. The ability of the handset receiver to select among many other signals, no matter how minute they are and reject all other unwanted strong signals is what this...

Linear and circular polarized antennas in a multipath environment, 1999

 Item — Call number MU Thesis Hak
Identifier: b2087986
Abstract Current issues have arisen in areas of cost savings and complexity of systems developed for the US Army. One of these systems is an identification system for ground vehicles. The issue for this system is whether the system should utilize circular polarized or linear polarized antennas. The identification system will be operating in the millimeter wave spectrum. The system is a question and answer system, therefore, the signal transmitted only needs to reach the receiver, where a reply is...

Low power radiofrequency radiation exposure hazards, 1999

 Item — Call number MU Thesis Kie
Identifier: b2087939
Abstract In wireless communications the electromagnetic interaction between the antennas of portable devices and the human body is of prime importance. This paper provides a thorough evaluation of the potential biological effects of low power radiofrequency radiation exposure by reviewing the available data from research performed to date by industry, academia, and the government. The results of experimentation, simulations, and studies will be used to compare the possible thermal and athermal...

Unambiguous direction of arrival computations using RF phase interferometers and the estimation of a RF transmitter's location using direction of arrival, 1997

 Item — Call number MU Thesis Ven
Identifier: b2194887
Abstract The primary purpose of this paper is to explore the principles involving radio interferometry. Radio interferometry provides the capability to derive the direction of arrival (DOA) of radio frequency signals. The direction of arrival is generated from the signal characteristics of an incoming plane wave which was generated by some unknown emitter. This paper discusses the use of a four element linear array as a phase interferometer to compute the direction of arrival of an incoming RF...
