Secure Power Grid Infrastructure Simulation And Test-Bed System Creation, Nelson Cristaldo Jul 2007

Secure Power Grid Infrastructure Simulation And Test-Bed System Creation, Nelson Cristaldo

FIU Electronic Theses and Dissertations

This thesis describes the design and construction of the test-bed system as well as its implementation to simulate the distributed control scheme. Some important elements of the system incorporate flexible power system network hardware and a data acquisition (DAQ) system to evaluate the issues that could trigger cascaded failures.

The objective of this research was to create an integrated simulation environment that represents the power system devices, the control, the protection, and the communication subsystems in the same simulation environment. We have utilized this simulator to conduct system studies and evaluate the interaction between power system components under steady-state and …


Fabrication And Characterization Of Three-Dimensional Magnetic Media, David Doria Jun 2007

Fabrication And Characterization Of Three-Dimensional Magnetic Media, David Doria

FIU Electronic Theses and Dissertations

Conventional longitudinal magnetic recording has scarcely progressed the last couple of years, leaving the data storage industry frantically searching for alternative ways to store information and increase memory areal density. The research was directed towards the development of three-dimensional magnetic memory for recording purposes. Three-dimensional memory, an alternative to longitudinal recording, would achieve well over the current areal density of the latter. Another focus of the research was directed towards development of the magneto-optical Kerr effect (MOKE) magnometer, an important tool used to measure magnetic behavior through hysteresis curves.

The fabrication of three-dimensional media was prepared with the aid of …


A Method For Enhancing Digital Information Displayed To Computer Users With Visual Refractive Errors Via Spatial And Spectral Processing, Miguel Alonso Jr. May 2007

A Method For Enhancing Digital Information Displayed To Computer Users With Visual Refractive Errors Via Spatial And Spectral Processing, Miguel Alonso Jr.

FIU Electronic Theses and Dissertations

This research pursued the conceptualization, implementation, and verification of a system that enhances digital information displayed on an LCD panel to users with visual refractive errors. The target user groups for this system are individuals who have moderate to severe visual aberrations for which conventional means of compensation, such as glasses or contact lenses, does not improve their vision.

This research is based on a priori knowledge of the user's visual aberration, as measured by a wavefront analyzer. With this information it is possible to generate images that, when displayed to this user, will counteract his/her visual aberration. The method …


Physical Dynamic Simulation Of Shipboard Power System Components In A Distributed Computational Environment, Nagy Youssef Abed Mar 2007

Physical Dynamic Simulation Of Shipboard Power System Components In A Distributed Computational Environment, Nagy Youssef Abed

FIU Electronic Theses and Dissertations

Shipboard power systems have different characteristics than the utility power systems. In the Shipboard power system it is crucial that the systems and equipment work at their peak performance levels.

One of the most demanding aspects for simulations of the Shipboard Power Systems is to connect the device under test to a real-time simulated dynamic equivalent and in an environment with actual hardware in the Loop (HIL). The real time simulations can be achieved by using multi-distributed modeling concept, in which the global system model is distributed over several processors through a communication link. The advantage of this approach is …
