The Capillary-Centric Model of Coupling-As-Thermodynamics
(North Dakota State University, 2015)
Models of ventricular-arterial coupling (VAC) have historically described the heart as a
function of its energetic interaction with the arterial system. However, these models either
represent the dynamic, adaptive ...
Intelligent and Efficient Embedded Video Memory Design in the Era of Big Data
(North Dakota State University, 2017)
The growing popularity of smart phones, tablets, and other mobile devices has created an exponential demand for video applications in today’s society. Mobile device users want their devices to achieve a long battery lifetime ...
Perceptions of Emergency Managers on Vulnerability and Institutional Preparedness of Colleges and Universities in the Red River Valley
(North Dakota State University, 2016)
The present study examines emergency management related perceptions of campus officials who are responsible for overseeing the general disaster preparedness of at five diverse colleges and universities in the Red River ...
Hybrid Renewable Energy System Using Doubly-Fed Induction Generator and Multilevel Inverter
(North Dakota State University, 2012)
The proposed hybrid system generates AC power by combining solar and wind energy converted by a doubly-fed induction generator (DFIG). The DFIG, driven by a wind turbine, needs rotor excitation so the stator can supply a ...
Designing of a Small Wearable Conformal Phased Array Antenna for Wireless Communications
(North Dakota State University, 2012)
In this thesis, a unique design of a self-adapting conformal phased-array antenna system for wireless communications is presented. The antenna system is comprised of one microstrip antenna array and a sensor circuit. A 1x4 ...
Capacity Region of Two Interfering Mimo Multiple Access Channels With Strong Interference
(North Dakota State University, 2015)
We consider a communication network, where two mutually interfering 2-user MIMO Multiple Access Channels (MAC) operate simultaneously via the same time-frequency space, and characterize the capacity region of this network ...
A Metamaterial-Based Multiband Phase Shifter
(North Dakota State University, 2014)
A design methodology for a multi-band phase shifter using a metamaterial-based transmission line was developed. This method is different in that the loaded-line phase shifter has a phase shift of 90 degrees at the center ...
Low-Cost Passive UHF RFID Tags on Paper Substrates
(North Dakota State University, 2014)
To reduce the significant cost in the widespread deployment of UHF radio frequency identification (RFID) systems, an UHF RFID tag design is presented on paper substrates. The design is based on meander-line miniaturization ...
Encoding Efficient Attributes Using Prime Modulo Method For Anonymous Credentials
(North Dakota State University, 2015)
The thesis explains a new method of encoding binary and finite set attributes in the anonymous credential system. To encode each binary and finite set attribute, we used the Chinese remainder theorem instead of using prime ...
The Design and Analysis of a Conformal Spiral Antenna Structure for an Ultra-Wide-Band Radar System
(North Dakota State University, 2016)
This thesis explores the design, simulation, and analysis of two conformal spiral antenna
structures that are used for an ultra-wide-band (UWB) bistatic radar. The radar antenna system
operates over a frequency range ...
