Investigation of Antenna Edge Treatments and Ground Plane Coupling Behavior
(2016-12-16)
Guided wave structures can perform as broadband antenna elements through the use of a gradual impedance transformation. The impedance match is typically created through gradual structural changes to match the impedance of ...
Simulation of Polarimetric Phased Array Weather Radars
(2016-05)
Polarimetric phased array radars (PPARs) are a rapidly developing area of research interest in weather radar. However, they present intrinsic challenges for calibration and operation. Foremost among these are the adverse ...
Investigation of Low-Power Antenna Reconfiguration Through Biasing of Magnetic Loads
(2017-05-12)
In modern RF systems, tunable devices are increasingly necessary to provide agility in crowded spectral environments. The antenna, as an integral part of any wireless system, must be capable of operating well at multiple ...
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, ...
DETECTABILITY ASSESSMENT OF THE HIGH-ENERGY X-RAY IN-LINE PHASE CONTRAST PROTOTYPE FOR DENSE BREASTS
(2018-12-14)
The primary objective of the research in this thesis is to evaluate the performance of the high-energy in-line phase contrast prototype with the conventional mammography along with ultrasound systems in the detection of ...
Simulation and Adaptive Aperture Allocation for All-Digital Phased-Array Radar
(2019-08-01)
Increased flexibility afforded by all-digital radar architectures and operational concepts such as MIMO radar can be leveraged with new waveforms and aperture allocation methods to improve radar performance in diverse ...
IOT system for Bluetooth based Origin-Destination studies
(2019)
Designing and modelling a transportation system is a complicated, yet crucial task that demands comprehensive study of public needs. An important aspect of the process is specifying the characteristics of traffic schemes, ...
Electroencephalographic Signatures in Developing Motor Brain of Infants at Time of Crawling Skill Acquisition
(2017-08-01)
Electroencephalography (EEG) is the aggregate of electrical signals emitted from the brain. Study of EEG has been widely used as a useful noninvasive method of collecting bioelectric signals from humans. Processing and ...
Potential Application of Machine Learning in Optical Communication Systems
(2017-07-07)
In this work, we will examine practically encoding information in the state of polarization using M- POLSK. We employ polarization-shift keying (POLSK) to generate an expected pattern of changing states of polarization ...
LARGE-SCALE DATA PROCESSING FOR DETECTING ACTIVITY ZONES IN MILAN
(2017-08)
Small cell networks are complements for existing networks to improve quality of service (QoS), capacity, and coverage. The primary purpose of this thesis is to mine mobile network data to provide an algorithm that mobile ...
