Individualized Cardiac Resynchronization Therapy: Next Generation Pacemaker Controls
(North Dakota State University, 2015)
Cardiac dyssynchrony (CD) causes some heart muscle regions to contract at different times, and current treatments do not help 30 – 50% of patients. In this thesis, multi-site pacing control schemes are created to quantitatively ...
Timed Refinement for Verification of Real-Time Object Code Programs
(North Dakota State University, 2018)
Real-time systems such as medical devices, surgical robots, and microprocessors are safety-critical
applications that have hard timing constraint. The correctness of real-time systems is
important as the failure may ...
Power System Stability Enhancement through Data Center Ancillary Services
(North Dakota State University, 2015)
The primary objective of a control system is stability and steady-state performance under varying dynamics, such as faults and disturbances. The stable power system should continue to function properly in case of faults ...
Damping Interarea Oscillations in Power Systems with DFIG
(North Dakota State University, 2011)
With rapid depletion of fossil fuels and increasing environmental concerns, the trend to capture renewable energy, especially through wind energy resources, is increasing. The doubly fed induction generator (DFIG) is the ...
Enhanced Augmented Reality Framework for Sports Entertainment Applications
(North Dakota State University, 2015)
Augmented Reality (AR) superimposes virtual information on real-world data, such as displaying useful information on videos/images of a scene. This dissertation presents an Enhanced AR (EAR) framework for displaying useful ...
Intelligent Efficient On-Chip Memory for Mobile Video Streaming
(North Dakota State University, 2017)
The growing popularity of powerful mobile devices such as smart phones and tablet devices has resulted in the exponential growth of demand for video applications. User experience and battery life are both crucial topics ...
High Power Density GaN Based Boost Inverter and Resonant Modular Multilevel Boost Converter for Automotive Applications
(North Dakota State University, 2018)
With the rise in demand for electric vehicles increasing, the need for high efficiency electrification systems is in high demand. One challenge is keeping full output power to the electric drives as the vehicle battery ...
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 ...
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 ...
Energy Efficient Data Centers for On-Demand Cloud Services
(North Dakota State University, 2015)
The primary objective of the Data Centers (DCs) is to provide in-time services to the cloud customers. For in-time services, DCs required an uninterruptable power supply at low cost. The DCs’ power supply is directly linked ...
