The Relationship Between Optokinetic Nystagmus And Caloric Weakness, D'Arcy D. Cyr
The Relationship Between Optokinetic Nystagmus And Caloric Weakness, D'Arcy D. Cyr
USF Tampa Graduate Theses and Dissertations
Traditionally, results from caloric testing and optokinetic nystagmus (OKN) testing are analyzed separately because caloric testing is a measure of peripheral function and OKN testing is considered to be a measure of central function. However, there is a connection between the visual system and the vestibular system in the vestibular nucleus of the brainstem. The purpose of this paper was to determine whether a relationship exists between optokinetic nystagmus results and unilateral caloric weakness results. This was determined by conducting a retrospective study of forty patients who exhibited a unilateral caloric weakness greater than or equal to twenty percent and …
Design And Characterization Of Multi-Layer Coplanar Waveguid Baluns And Inductors, Khaled Obeidat
Design And Characterization Of Multi-Layer Coplanar Waveguid Baluns And Inductors, Khaled Obeidat
USF Tampa Graduate Theses and Dissertations
This work examined the design and characterization of multilayer coplanar waveguide baluns and inductors. This work derives a design procedure that helps RF engineers design cost effective multilayer coplanar waveguide (CPW) spiral balun that works in the frequency range 1-8 GHz. The accuracy of the developed procedure has been proven by designing two balun circuits of different dimensions and simulating them using available commercial software, Momentum (MoM) and Empire (FDTD). The simulation results have shown good balun performance over the desired frequency range. Furthermore some of the designed balun circuits have been fabricated and measured and the results agree with …
