Adaptive Beamforming for Antennas on General Wedge- and Cylindrical-Shaped Surfaces
(North Dakota State University, 2014)
Adaptive beamforming antennas capable of accommodating the growing number of wireless subscribers throughout the world has become an essential part of modern wireless systems. In this work, the beamforming of a conformal ...
Weak Power Grid Analysis for Renewable Energy Sources Integration
(North Dakota State University, 2019)
Weakness analysis based on grid strength assessment is useful for identifying potential weak grid issues. However, when taking into account the impact of the interactions among Renewable Energy Sources (RESs), the weakness ...
Perceptual Video Quality Model and its Application in Wireless Multimedia Communications
(North Dakota State University, 2015)
With the exponential growth of video traffic over wireless networked and embedded
devices such as mobile phones and sensors, mechanisms are needed to predict the perceptual
quality of video in real time and with low ...
Conformal Antennas and Arrays with Layers Consisting of Copper and Graphene-based Conductors for Redundancy Properties
(North Dakota State University, 2017)
Graphene is a new promising material with unique electrical, mechanical, optical and thermal characteristics. The use of graphene in the design of an antenna and other electromagnetic passive devices would be beneficial ...
Characterization of a Structure Consisting of Magnetostatic Responsive Microscopic Particles and Its Applications In Antennas
(North Dakota State University, 2015)
Wireless communication systems often require that a single antenna work
at different frequencies. Thus the recon gurable antennas are useful in frequency
agile environments to receive a signal over multiple bands. Research ...
Equivalent Circuit Modeling and Signal Integrity Analysis of Magneto-Static Responsive Structures, and Their Applications in Changing The Effective Permittivity of Microstrip Transmission Lines
(North Dakota State University, 2016)
This work presents the equivalent circuit model, ringing and overshoot characteristics, as
well as the ability of a new magneto-static responsive structure (MRS) to achieve the recon gurabil-
ity of a variable e ective ...
Formal Verification Methodology for Asynchronous Sleep Convention Logic Circuits Based on Equivalence Verification
(North Dakota State University, 2019)
Sleep Convention Logic (SCL) is an emerging ultra-low power Quasi-Delay Insensitive (QDI) asynchronous design paradigm with enormous potential for industrial applications. Design validation is a critical concern before ...
Design of High Power Density Switched Capacitor DC-DC Converter
(North Dakota State University, 2017)
Design and implementation of high power density and high efficiency dc-dc converters has been a primary component for reducing energy cost. Traditionally dc-dc converters are composed with silicon based technology that has ...
