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 ... -
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 ... -
The Effects of Spatial and Temporal Properties on a Viscoelastic Model of the Dyssynchronous Canine Heart
(North Dakota State University, 2011)In this study, lumped parameter cardiovascular modeling has been used to understand the influence of muscle properties on mechanical dyssynchrony (MD) as well as general muscle dynamics. Incorporating viscous influence ... -
Design of a Reconfigurable Pulsed Quad-Cell for Cellular-Automata-Based Conformal Computing
(North Dakota State University, 2011)This paper presents the design of a reconfigurable asynchronous unit, called the pulsed quad-cell (PQ-cell), for conformal computing. The conformal computing vision is to create computational materials that can conform to ... -
Thermo-Mechanical Selective Laser Assisted Die Transfer
(North Dakota State University, 2011)Laser Induced Forward Transfer (LIFT) techniques show promise as a disruptive technology which will enable the placement of components smaller than what conventional pick-and-place techniques are capable of today. Limitations ... -
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 ... -
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, ... -
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 ... -
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 ... -
A PMSG-Based Wind Energy Conversion System Assisted by Photovoltaic Power
(North Dakota State University, 2012)This work discusses a hybrid power conversion scheme consisting of a permanent magnet synchronous generator (PMSG)-based wind energy system and photovoltaic panels. The two energy sources are integrated with a battery to ... -
Hybrid Renewable Energy System Using Doubly-Fed Induction Generator and Multilevel Inverter
(North Dakota State University, 2012)The proposed hybrid system generates AC power by combining solar and wind energy converted by a doubly-fed induction generator (DFIG). The DFIG, driven by a wind turbine, needs rotor excitation so the stator can supply a ... -
