Application of multispectral color photography to flame flow visualization

For flames of short duration and low intensity of radiation a spectroscopical flame diagnostics is difficult. In order to find some other means of extracting information about the flame structure from its radiation, the feasibility of using multispectral color photography was successfully evaluated. Since the flame photographs are close-ups, there is a considerable parallax between the single images, when several cameras are used, and additive color viewing is not possible. Each image must be analyzed individually, it is advisable to use color film in all cameras. One can either use color films of different spectral sensitivities or color films of the same type with different color filters. Sharp cutting filters are recommended

Diffractive and deeply virtual Compton scattering in holographic QCD

We further analyze the holographic dipole-dipole scattering amplitude developed in arXiv:1202.0831, 1205.3223. Gribov diffusion at strong coupling yields the scattering amplitude in a confining background. We compare the holographic result for the differential cross section to proton-proton and deeply virtual Compton scattering data

Enabling Distributed Simulation of OMNeT++ INET Models

Parallel and distributed simulation have been extensively researched for a long time. Nevertheless, many simulation models are still executed sequentially. We attribute this to the fact that many of those models are simply not capable of being executed in parallel since they violate particular constraints. In this paper, we analyze the INET model suite, which enables network simulation in OMNeT++, with regard to parallelizability. We uncovered several issues preventing parallel execution of INET models. We analyzed those issues and developed solutions allowing INET models to be run in parallel. A case study shows the feasibility of our approach. Though there are parts of the model suite that we didn't investigate yet and the performance can still be improved, the results show parallelization speedup for most configurations. The source code of our implementation is available through our web site at code.comsys.rwth-aachen.de.Comment: Published in: A. F\"orster, C. Sommer, T. Steinbach, M.

Improved AdS/QCD Model with Matter

We study an improved AdS/QCD model at finite temperature and chemical potential. An Ansatz for the beta-function for the boundary theory allows for the derivation of a charged dilatonic black hole in bulk. The solution is asymptotically RN-AdS in the UV and AdS2 * R3 in the IR. We discuss the thermodynamical aspects of the solution. The fermionic susceptibilities are shown to deviate from the free fermionic limits at asymptotic temperatures despite the asymptotically free nature of the gauge coupling at the boundary. The Polyakov line, the temporal and spatial string tensions dependence on both temperature and chemical potential are also discussed

Life, Strength, Woman: English Translation of Julia de Burgos’s Poetry

The purpose of this translation project is to make Puerto Rican feminist and political activist Julia de Burgos’s poetry available to a wider audience. Its feminist themes and exploration of powerful emotions are just as relevant today as they were in Burgos’s lifetime. Translating these poems to English in the twenty-first century means a whole new generation of developing women will have access to Burgos’s words. They will feel Burgos’s deep and intricate emotions and understand that it’s okay to struggle as long as they remain true to themselves. A detailed history of Burgos’s life accompanies the translated poems in order to give a broader view of Burgos’s passions and experiences and to help readers understand Burgos’s politically charged poems. A scholarly analysis of my translation process is also included to explain how I narrowed down my selection to 21 poems that capture not only the spirit and style of Burgos, but also represent poetry from across her lifetime on a variety of subjects. I also deliberately included poems with unique form, as Burgos’s poetry shows her individualism in its form as well as its voice. This translation project will be a useful resource for anyone studying Puerto Rican history as well as for today’s women, who will surely be inspired by Burgos’s empowering words
