Anderson Localization in Quark-Gluon Plasma

At low temperature the low end of the QCD Dirac spectrum is well described by chiral random matrix theory. In contrast, at high temperature there is no similar statistical description of the spectrum. We show that at high temperature the lowest part of the spectrum consists of a band of statistically uncorrelated eigenvalues obeying essentially Poisson statistics and the corresponding eigenvectors are extremely localized. Going up in the spectrum the spectral density rapidly increases and the eigenvectors become more and more delocalized. At the same time the spectral statistics gradually crosses over to the bulk statistics expected from the corresponding random matrix ensemble. This phenomenon is reminiscent of Anderson localization in disordered conductors. Our findings are based on staggered Dirac spectra in quenched SU(2) lattice simulations.Comment: 11 pages, 8 figure

Heterogeneous conductivity parameters in a one dimensional fuel cell model

A model of one dimensional fuel cells is investigated, where the material inhomogeneities in the cathode are taken into account. We use the results in some preceding studies to describe the dynamics of the chemical reactions and transport of ions. A corresponding governing equation is derived for the numerical simulations. We apply an explicit-implicit time integration and Richardson extrapolation technique to increase the accuracy of the approximations. The efficiency of the method is demonstrated using a non-trivial test problem with real parameters. Numerical simulations are executed in presence of inhomogeneous conductivities and their effect on the cell potential is investigated

Structural information aided automated test method for magic 4GL

Nowadays testing data intensive, GUI enhanced applications properly on an easily maintainable way has become a more crucial part of the application life cycle. There are many evolving technologies to support automatized GUI testing in various environments. However there are hardly any methods that support 4GLs, especially Magic. Fortunately, the characteristics of the 4th generation of programming languages - like explicit definition of the relations between GUI elements and data - eliminate most of the problems raised during testing the GUI in the case of 3GLs. By utilizing these advantages we were able to develop a generalized testing method that supports 4GLs, and as a proof of concept a system for testing Magic xpa applications was built. In this paper, a generalized testing method for 4GLs, our path and script generator algorithms, and their implementations for Magic xpa applications are presented. In addition, the cooperation of these components with existing solutions is demonstrated, and a test method that has been competed by the application of our tools (and which is an instantiation of the generalized method) is introduced as a possible use of the results

Using of Bioethanol Fuels in IC Engine

Renewables - excluding large hydro accounted for 48% - increased to 15.2% of world cumulative generation capacity in 2014, from 13.8% in 2013. In the EU, the European Parliament approved a reform of the 2020 biofuels target. The new version of the Renewable Energy Directive (RED) distributes the 10% cal. biofuels target into a share for crop-based biofuel (limited at 7% cal.) with the rest to be met with another biofuels and renewable electricity containing multiple counting possibilities. Merely 2% of the EU’s fuel consumption can be covered by its own researches, which looks good pretend a strong dependence on the oil exporting countries. The implementations of biogenic fuels produced from fast growing plant is continuously gaining in importance with regard to economic and environmental effects. Generally they are not offered in their pure form but just as blend components to conventional fuels. Their mixtures can bring about fundamental feature improvements. Ethanol fuel output in 2015 reached a peak high helped by rising gasoline demand in the US. Besides, the changes in the fuel taxation in Brazil and an increase in the minimum blending ratio also pushed along the ethanol fuel demand. The weaker euro and low grain prices on the back of a record wheat crop turned into a considerable growth in output in the EU. Disregard the stimulating developments on the legislative side, it must also be confessed that the decreasing crude oil prices took their customs on the 2015 biofuel markets. For ethanol fuel, more growth could theoretically arrive from an extending of E-10 in EU member states. Unnecessary to discuss that an outlook for a post-2020 biofuels target at the EU level does not valid

A plant breeding approach to eliminate the development of calcium deficiency symptoms in sweet pepper growing

Plants show significant differences regarding the dynamics of the uptake and transport of the nutrients. The results of our experiments gave an explanation of the fact that the Ca2+ uptake and transport ability of pepper is different in each genotype. The Ca2+ requirement of the fruits of certain varieties is significantly higher than the amount the plant itself can take up. The determined selection and the further breeding work aimed to solve this anomaly and enable the safe growing of sweet pepper irrespectively of the CaCO3 level of the soil. The basic goal of our breeding work was to improve the calcium utilization efficiency of the tomato-shaped sweet pepper variety ’PAZ’ which is sensitive to calcium deficiency. Crossing with a suitable partner (Torkál F1) resulted in a hybrid (Tokyo) the Ca2+ uptake, translocation and ecological adaptability of which proved to be far better compared to the free-pollinating variety. Regarding fruit quality, the hybrid did not leg behind the biological and consumers’ values of the parental genotypes
