Fault Tolerant and Adaptive Systems with Focus on Networks-On-Chips
(North Dakota State University, 2014)
The first step in design of reliable systems is the ability to evaluate the reliability of the system. This is an important step in the process of designing reliable systems because design techniques that proactively improve ...
Network Convergence in Multicarrier Hybrid Cellular Network
(North Dakota State University, 2014)
In a multicarrier communication system with known channel state information at transmitter (CSIT), it is well-known that the water-filling power allocation scheme is optimal in achieving the Shannon capacity. However, in ...
On the Secrecy Capacity of Fading Gaussian Wire-Tap Channel
(North Dakota State University, 2014)
We consider the so called “wire-tap channel”, where a transmitter sends secret information to its receiver in the presence of an eavesdropping receiver with similar signal processing capability as the desired receiver. It ...
Interior Permanent Magnet Synchronous Motor Demagnetization Fault Modeling and Analysis by Using Dynamic Phasors Model
(North Dakota State University, 2014)
Interior permanent magnet synchronous motor (IPMSM) has been widely used in hybrid electric vehicles (HEVs) since the high power density and efficiency. However, the primary drawback of IPMSM is the demagnetization phenomenon ...
Design and Analysis of New Printed Wideband Antennas for Wireless Applications
(North Dakota State University, 2014)
In this study a simple method to develop a wideband antenna is proposed. With this new technique a dipole antenna with a 48% frequency bandwidth is transformed to achieve a 120% frequency bandwidth for a voltage standing-wave ...
A Conceptual Model of the Individual and Household Recovery Process: Examining Hurricane Sandy
(North Dakota State University, 2014)
This study examined how comprehensively the Bolin and Trainer (1978) model of recovery reflects the recovery process of individuals and households. A review of the literature since 1978 suggested that various revisions and ...
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 ...
Using Formal Methods to Validate the Usage, Protocols, and Feasibility in Large Scale Computing Systems
(North Dakota State University, 2014)
A paradigm shift has occurred in the Information and Communication Technology sector. The main obstacle to relegate complex and sensitive tasks is not the inadequate speed and unsatisfactory computing power of the existing ...
A New Methodology for the Design and Tuning of Robust PID Controllers in Electric Drives
(North Dakota State University, 2014)
AC induction motor-drive systems are the backbone for numerous industrial
applications, such as aerospace, medical equipment, and nuclear power plants.
The control performance of electric drives is sensitive to several ...
