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 ... -
Metamaterial-Inspired Reconfigurable Series-Fed Arrays
(North Dakota State University, 2014)One of the biggest challenges in modern day wireless communication systems is to attain agility and provide more degrees of freedom in parameters such as frequency, radiation pattern and polarization. Existing phased array ... -
Microwave Measurement of Grain and Biomass
(North Dakota State University, 2022)Microwave measurement is a powerful method for mass prediction and grain detection. Existing systems are well adapted for small volume grain measurements, but cannot accommodate materials other than grain (e.g. biomass), ... -
Minimum Entropy Generation in the Cardiovascular System
(North Dakota State University, 2011)This study was performed under the motivation to find a scheme that could describe the complex behavior of cardiovascular homeostasis. This is hypothesized to be manifested in a thermodynamic description of the cardiovascular ... -
Mitigating Nonlinear Effect and Preserving Privacy for Memristor Based On-Chip Neural Network
(North Dakota State University, 2021)Memristors offer advantages as a hardware solution for neuromorphic computing, however, their non-ideal property makes the weight update difficult and reduces the accuracy of a neural network. Also, a large amount of ... -
Multisine Excitation Design to Increase the Efficiency of System Identification Signal Generation and Analysis
(North Dakota State University, 2012)Reducing sample frequencies in measurement systems can save power, but reduction to the point of undersampling results in aliasing and possible signal distortion. Nonlinearities of the system under test can also lead to ... -
A Negative Dielectrophoresis Based Method of Detecting Pancreatic Cancer Antigen CA 242 in Serum
(North Dakota State University, 2020)Patients with pancreatic cancer in metastasis rarely survive, thus the need for diagnostic tools for early stage detection. Current techniques such as ELISA and SPR are complex and expensive and cannot detect cancer in its ... -
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 ... -
A New Generation of Particle-Based Radio Frequency (RF) Switches for Portable and High-Frequency Applications
(North Dakota State University, 2019)Reconfigurable and tunable designs which provide multi-functionality are highly desirable in wireless communication systems. Amongst different methodologies to design RF switching, a directly connected biasing circuitry ... -
A New Method of Dynamic Reliability Management for Chip Multi-Processors
(North Dakota State University, 2014)This work presents a new dynamic reliability management controller which successfully extends the expected lifetime of Chip Multi-Processors (CMPs). This is achieved by migrating tasks within the CMP, effectively reducing ... -
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 ... -
