A Study of Conformal Metasurfaces on Passive Beam Steering for Arrays
(North Dakota State University, 2022)
Beam-steering has drawn significant interest due to the expansion of network capacity. However, a traditional beam steering system involves active phase shifters and controlling networks which can be complex. This work ...
Lithium Ionic Conductivity and Stability Of Cubic Li7La3Zr2O12 Solid Electrolyte A First-Principles Study
(North Dakota State University, 2020)
Garnet structured cubic LLZO crystal (Li56La24Zr16O96) is one of the most promising solid electrolytes for next-generation solid-state lithium-ion batteries. Ab initio molecular dynamics simulations have been employed to ...
Intelligent Energy-Efficient Storage System for Big-Data Applications
(North Dakota State University, 2020)
Static Random Access Memory (SRAM) is a critical component in mobile video processing systems. Because of the large video data size, the memory is frequently accessed, which dominates the power consumption and limits battery ...
Development of Performance Optimized Rotation Tolerant Viola-Jones Based Blackbird Detection, a Throughput Optimized Asynchronous Mac Implementation, and Automated Wheat Lodging Estimation
(North Dakota State University, 2020)
The research described in this doctoral dissertation focuses on three main topics:1) performance optimization of the Viola-Jones Algorithm (VJA) for red-winged blackbird (Agelaius phoeniceus) detection, 2) further increasing ...
A Study of Inverter-Based Resources on Power Grid Operation Under Uncertain Operating Conditions
(North Dakota State University, 2022)
The electric power grid is undergoing a rapid change predominantly driven by high penetration levels of renewable energy resources (RERs) such as wind and solar. These resources are interfaced with the power grid through ...
Formal Verification Methodologies for NULL Convention Logic Circuits
(North Dakota State University, 2020)
NULL Convention Logic (NCL) is a Quasi-Delay Insensitive (QDI) asynchronous design paradigm that aims to tackle some of the major problems synchronous designs are facing as the industry trend of increased clock rates and ...
Rare Molecule Biomarker Detection Using Dielectrophoresis Spectroscopy
(North Dakota State University, 2021)
According to the American cancer society, 1.9 million new cancer cases and 608,570 cancer deaths are projected to occur in the United States. There is a fundamental technology gap that prevents the availability of tools ...
Wide Band-Gap Semiconductor Based Power Converter Reliability and Topology Investigation
(North Dakota State University, 2020)
Wide band-gap semiconductor materials such as silicon carbide (SiC) and gallium nitride (GaN) have been widely investigated these years for their preferred operation at higher switching frequency, higher blocking voltage, ...
Resilient Monitoring and Robust Control towards Blackout Prevention in Modern Power Grids
(North Dakota State University, 2020)
This dissertation embodies a comprehensive approach towards resilient monitoring of frid events using Structure Preserving Energy Functions (SPEFs) and introduces a novel control architecture in Multi Terminal Direct Current ...
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 ...
