Characterization And Modeling Of Multi-Conductor Transmission Line Using Finite-Difference Time-Domain Method, Sanjay Bajracharya
Characterization And Modeling Of Multi-Conductor Transmission Line Using Finite-Difference Time-Domain Method, Sanjay Bajracharya
FIU Electronic Theses and Dissertations
A two-dimensional, 2D, finite-difference time-domain (FDTD) method is used to analyze two different models of multi-conductor transmission lines (MTL). The first model is a two-conductor MTL and the second is a threeconductor MTL. Apart from the MTL's, a three-dimensional, 3D, FDTD method is used to analyze a three-patch microstrip parasitic array. While the MTL analysis is entirely in time-domain, the microstrip parasitic array is a study of scattering parameter Sn in the frequency-domain. The results clearly indicate that FDTD is an efficient and accurate tool to model and analyze multiconductor transmission line as well as microstrip antennas and arrays.

FIU Electronic Theses and Dissertations
The objective of this work is to design, simulate and synthesize a dynamic space controller system. The concept of space allocation and management can be applied to more than physical space. It may also be taken in the contexts of memory, network or bus management. The management and allocation of any space depends mostly on the twin factors of demand and availability. Time, the size and amount of space available, as well as the number of requests for the spaces, must also be considered. The proposed design has the capability to monitor multiple spaces for vacancies, length of time occupied …

A New Microprocessor-Controlled Stimulator For Visual Evoked Potential Acquisition, Octavio Gabriel Garrastacho
FIU Electronic Theses and Dissertations
The goal of this study was to develop two computer-controlled visual evoked potential (VEP) stimulators. The first device employs a 12 x 12 matrix of 5 mm square Light Emitting Diodes (LEDs) and is housed in an 8 x 8 utility box structure. The second device employs two 8x8 matrices of 3 mm square LEDs, each housed in one eyepiece of a goggle-like structure. A quantitative comparison of the performance of these stimulators was carried out in terms of absolute and interpeak latencies, signal-to-noise ratio (SNR) and cross-correlation between sequential responses obtained from them. Six normal adult subjects were involved …
