Magnetoinductive waves propagating along a line consisting of two kinds of metamaterial elements are studied. Both elements are made up by the same metallic loop but are loaded by different capacitors resulting in different resonant frequencies. The dispersion characteristics are derived from phase and amplitude measurements for the cases when the line consists of (i) identical elements and (ii...

Abstract: This paper investigates the trajectory prediction and dispersion for unguided fin stabilized artillery rocket in order to explain the importance of the rocket production accuracy and the benefit of using guided rockets. The total dispersion results mainly from three effects. The first is the dispersion due to rocket production inaccuracy, which includes propellant mass, composition in...

Aperture coupling is the main coupling mode through which electromagnetic pulse (EMP), ultra wideband (UWB) and high power microwave (HPM) can disturb or damage electronic equipments of the missile enclosure. To get knowledge of the coupling effects of apertures with different shapes and positions, coupling processes of HPM into the missile enclosure are investigated. The simulation results ind...

We analyze the structure of noncommutative pure Chern-Simons theory systematically in the axial gauge. We show that there is no IR/UV mixing in this theory in this gauge. In fact, we show, using the usual BRST identities as well as the identities following from vector supersymmetry, that this is a free theory. As a result, the tree level Chern-Simons coefficient is not renormalized. It also hol...

In order to more accurately asses variations in the apparent diffusion coefficient used for therapy evaluation, we have studied the variation in sulci density in the human brain. Sagittal, axial and coronal magnetic resonance imaging scans have been analyzed to determine the change of the coefficient of variance of pixel intensity as a function of position. In the sagittal direction, relative t...

In this paper, we extend the MURM (Modified Universe Reaction Model) of a CSTR to a tubular reactor with axial dispersion. Furthermore, we use this mixing model to study the effort of the micromixing on the steady state multiplicity for an autocatalytical reaction of tubular reactor.

This work compared the outcome of tracer dispersion experiments with the results of a far field numerical modeling. The studies were carried out on two different locations from Rio de Janeiro coast: the first near the city of Maricá, approximately 30 km east from the Guanabara Bay, and the second inside the bay, at São Gonçalo. For the tracer experiment, it was used a Rhodamine, Amidorhodamine ...
