F1.00001: Minor Corrections to Physics for Optimizing Homeland Security by Our Pal Asija Pal Asija To optimize Homeland security it must be based on correct physics. There is But ONE Reality of Physics and finding that rugged reality requires identifying and expunging erroneous knowledge. Six examples are included. \begin{enumerate} \item Lighter Bodies Travel Faster. (Aristotle got it backwards) \item Faster Objects Become Lighter. (Einstein got it backwards) \item Two Minor Corrections to Newton's First Law of Motion. \item Three D or No D (Any theory based on other than 3 D is fantastic) \item Gravity is A Local and Physical Contact Force \item Light is never Waves and Photons at the Same Instant. \end{enumerate} These corrections are then further delineated by several examples for leading and driving innovations in homeland security.

F1.00002: The Effects of Neutral Damping on Resistive Wall Mode Physics Royce James, K. Becker, J. Hanson, M.E. Mauel, D.A. Mauer, G.A. Navratil, T.S. Pedersen The physics of the dissipation mechanism responsible for rotational stabilization of the resistive wall mode (RWM) continues to be an object of intense current research. On the High Beta Tokamak -- Extended Pulse (HBT-EP), there is experimental evidence that edge neutral damping is a significant dissipation mechanism that affects tearing mode behavior [1]. To quantify the possible effect of neutral damping on RWM physics, we have constructed a 15-channel linear photo-detector array to measure D$_{\alpha}$ emission and its fluctuations. These measurements will be used in conjunction with a 1D space, 2D velocity kinetic transport model of the atomic and molecular deuterium penetration to quantify neutral profiles within the plasma [2]. Updates on efforts to measure the neutral damping contribution to RWM rotational stabilization utilizing the measured D$_{\alpha}{\rm g}$ profiles to estimate the edge neutral density will be presented. \newline [1] E.

F1.00003: Using Quaternions for Lagrangians in EM and GEM, a Unified Field Theory Douglas Sweetser Quaternions are a mathematical field like the real and complex numbers, that can be added, subtracted, multiplied or divided. I will show how to derive the gauge-invariant Maxwell field equations using quaternions. Using a variation on this approach, the gauge-invariant GEM field equations will be derived.

F1.00004: Properties of One Dimensional Layered DPS/DNG Photonic Crystal: Transmission and Reflection Joseph Shahbazian, Aram Karakashian In this project the main goal is to study the refraction and reflection of a one dimensional photonic crystal with alternating layers of DNG and DPS materials. The material's optical parameters, electric permittivity and magnetic permeability, are complex and frequency dependent. Here we present the refraction and reflection and also non-Bragg band gaps in a one dimensional photonic crystal composed of DNG and DPS layers. Our center of attention is the study of the zero permittivity, zero permeability and zero average refractive index gaps and the transmission and reflection of photons. [Preview Abstract] |
