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 ...
Contextualization in Large-Scale Social Networks
(North Dakota State University, 2014)
Social computing-based applications provide a coherent medium through which people can be interactive and socialize by developing a Web-based communication channel that integrates different Social Networking Services (SNSs) ...
Zeroth Order Resonator (ZOR) Based RFID Antenna Design
(North Dakota State University, 2014)
Meander-line and multi-layer antennas have been used extensively to design
compact UHF radio frequency identification (RFID) tags; however the overall size
reduction of meander-line antennas is limited by the amount of ...
A Compact Cylindrical-Shape Microstrip Structure with Cloaking Properties for Mutual Coupling Reduction in Array Antennas
(North Dakota State University, 2014)
A cylindrical-shaped microstrip structure with cloaking properties is presented as a shielding device to reduce the mutual coupling between two patch antennas. The surface comprises of a number of 2-port microstrip (2-PM) ...
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 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 ...
