Highly Miniaturized VHF Helical Filters with Fully Reconfigurable Capabilities
(2019-05-10)
The demand for frequency reconfigurable bandpass and bandstop filters within the VHF-UHF frequencies continues to rise due to the increasingly crowded radio frequency (RF) spectrum. As a result, higher levels of isolation ...
Creeping Wave Propagation On Cylindrical Radiating Structures
(2019-08-01)
Weather radar is a powerful tool for detecting hazardous weather that may impact
the lives of many. Most weather radars used by meteorologists today rely on a
mechanical sweep to obtain volumetric data. This mechanical ...
AI BASED FAULT DIAGNOSIS IN EMERGING CELLULAR NETWORKS
(2019-08)
Mobile cellular network operators spend nearly a quarter of their revenue on network management and maintenance. A significant portion of that budget, is spent on resolving faults diagnosed in the system that degrade or ...
Preliminary Study on Deterministic Chaotic System From Physical Approach
(2019-05-10)
Chaotic phenomenon widely exists in the nonlinear dynamic systems. Such phenomenon is described to be highly related the initial conditions and intrinsic system properties. Traditionally, large effort has been put on ...
TIME AND FREQUENCY CHARACTERISTIC OF 802.11AX
(2019-12-12)
Wireless Local Area Network (WLAN) is a wireless communication system that connects two or more devices using radio frequency to form a local network (LAN). WLAN is used inside buildings (e.g., apartment, campus, train ...
Objective Characterization of In-line Phase Contrast X-ray Imaging Prototype Using a Mid-energy Beam
(2019-08)
The purpose of the research presented in this thesis is the characterization of an in-line phase contrast x-ray imaging prototype operating at mid-energy, and to compare the data to that of high energy imaging with the ...
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, ...
Design of a Circularly Polarized Rectifying Antenna on a Flexible Substrate at X-Band
(2019-12-13)
This thesis lays out the design procedure for a left-hand circularly polarized, high-efficiency rectifying antenna on a flexible substrate for use at 10 GHz. The rectenna system is designed for space based power applications. ...
Antenna Synthesis Through Characteristic Modal Analysis for Small Unmanned Aerial System Applications
(2019-05-10)
Historically, antennas for airborne applications have been a separate class unto themselves. They have unique requirements for conformality, structural integrity, and long-range communication. Furthermore, the must ...
