A Precision Slip Frequency Detector
(North Dakota State University, 1957)The problem of measuring low values of slip of induction machines is present in most Electrical Engineering laboratories. A rather high accuracy of the determination is necessary for theoretical calculations of motor ... -
Solution Processing Electronics Using Si6 H12 Inks: Poly-Si TFTs and Co-Si MOS Capacitors
(North Dakota State University, 2011)The development of new materials and processes for electronic devices has been driven by the integrated circuit (IC) industry since the dawn of the computer era. After several decades of '"Moore's Law"-type innovation, ... -
Calculating Cardiovascular Lumped-Parameter Model Values by Injecting Small Volume Perturbations in an Isovolumic Heart
(North Dakota State University, 2011)Diagnosing cardiac patient problems contains many uncertainties, and to fully diagnose the patient's condition usually requires a lengthy drug regimen to see what works and what does not. Compounding this problem is that ... -
Impedance-Based Wireless Sensor Network for Metal-Protective Coating Evaluation
(North Dakota State University, 2011)Research has focused on the influences of flowing fluid on the corrosion of bare metals, but there is little emphasis on the degradation of metal-protective coating. Evaluating the metal-protective coating usually uses the ... -
Cardiac Output Improvement in Mechanical Circulatory Support Devices
(North Dakota State University, 2017)Mechanical circulatory support devices (MCSDs) have gained widespread clinical acceptance as an effective heart failure (HF) therapy. The concept of harnessing the kinetic energy (KE) available in the forward aortic flow ... -
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 Polynomial Time Procedure Converting Error Correcting Codes to Semantically Secure Wiretap Codes
(North Dakota State University, 2018)We furnish a procedure based on universal hash families that can convert an error correcting code of rate R to a semantically secure wiretap code of rate R−ξ where ξ is some parameter derived from the eavesdropper’s channel. ... -
Semantic Security for the Fast Fading Wiretap Channel.
(North Dakota State University, 2018)We provide a set of semantically secure achievable rates for the fast fading wiretap channel. In particular, we do so for the cases where there is channel state information at the transmitter (CSIT) for both the main and ... -
Dynamic Partial Reconfiguration as an Approach to Motor Control Design
(North Dakota State University, 2018)Recent work in motor controls has been utilizing the Field Programmable Gate Array (FPGA) instead of using the more standard microprocessors or digital signal processors. FPGAs have the advantage of flexibility and ... -
Thrombolysis of Blood Clots using Wirelessly Powered Inferior Vena Cava Filters
(North Dakota State University, 2018)Venous thromboembolisms (VTE) are estimated to affect up to 900,000 individuals in the U.S. each year. Traditionally, VTE is treated prophylactically with anticoagulants or directly with thrombolytic therapies. Both ... -
Design of High Power Density Switched Capacitor DC-DC Converter
(North Dakota State University, 2017)Design and implementation of high power density and high efficiency dc-dc converters has been a primary component for reducing energy cost. Traditionally dc-dc converters are composed with silicon based technology that has ... -
