Electromechanics Of An Ocean Current Turbine, Vasileios Tzelepis
Electromechanics Of An Ocean Current Turbine, Vasileios Tzelepis
University of New Orleans Theses and Dissertations
The development of a numeric simulation for predicting the performance of an Ocean Current Energy Conversion System is presented in this thesis along with a control system development using a PID controller for the achievement of specified rotational velocity set-points. In the beginning, this numeric model is implemented in MATLAB/Simulink® and it is used to predict the performance of a three phase squirrel single-cage type induction motor/generator in two different cases. The first case is a small 3 meter rotor diameter, 20 kW ocean current turbine with fixed pitch blades, and the second case a 20 …
Comparative Analysis Of Load Flow Techniques For Steady State Loading Margin And Voltage Stability Improvement Of Power Systems, Santosh Togiti
Comparative Analysis Of Load Flow Techniques For Steady State Loading Margin And Voltage Stability Improvement Of Power Systems, Santosh Togiti
University of New Orleans Theses and Dissertations
Installation of reactive compensators is widely used for improving power system voltage stability. Reactive compensation also improves the system loading margin resulting in more stable and reliable operation. The improvements in system performance are highly dependent on the location where the reactive compensation is placed in the system. This paper compares three load flow analysis methods - PV curve analysis, QV sensitivity analysis, and Continuation Load Flow - in identifying system weak buses for placing reactive compensation. The methods are applied to three IEEE test systems, including modified IEEE 14-bus system, IEEE 30-bus system, and IEEE 57-bus system. Locations of …
Automatic Classification Of Fish In Underwater Video; Pattern Matching - Affine Invariance And Beyond, Madhuri Gundam, Madhuri Gundam
Automatic Classification Of Fish In Underwater Video; Pattern Matching - Affine Invariance And Beyond, Madhuri Gundam, Madhuri Gundam
University of New Orleans Theses and Dissertations
Underwater video is used by marine biologists to observe, identify, and quantify living marine resources. Video sequences are typically analyzed manually, which is a time consuming and laborious process. Automating this process will significantly save time and cost. This work proposes a technique for automatic fish classification in underwater video. The steps involved are background subtracting, fish region tracking and classification using features. The background processing is used to separate moving objects from their surrounding environment. Tracking associates multiple views of the same fish in consecutive frames. This step is especially important since recognizing and classifying one or a few …
Visualization Of 4d Q2psk And Ce Q2psk In Ideal Bandlimited Channels, Milton I. Quinteros, Edit J. Kaminsky, Kenneth V. Cartwright
Visualization Of 4d Q2psk And Ce Q2psk In Ideal Bandlimited Channels, Milton I. Quinteros, Edit J. Kaminsky, Kenneth V. Cartwright
Electrical Engineering Faculty Publications
This paper presents new visualization techniques for 4D Quadrature-Quadrature Phase Shift Keying (Q2PSK), Saha’s Constant Envelope (CE) Q2PSK, and Cartwright’s CEQ2PSK in ideal bandlimited channels. The signal diagrams analyzed are: time-signal eye patterns for 4D passband signals, 2D complex trajectory diagrams of baseband signals, and time-signal eye patterns for the 1D outputs of the baseband matched filter. These methods may be applied to other multidimensional modulation systems to obtain insight into the effects of noise, interference, and channel filtering.
