Analyses of surplus traffic load in urban infrastructure

In the urban infrastructure, the factors affecting transport have been analysed. In order to solve the problem, practices of foreign countries have been considered. Offers on decreasing surplus traffic load, have been worked out

Reduzierung des Ascosporenpotentials von Venturia inaequlis durch Förderung der Fallaub-Zersetzung

The aim of this study was to investigate the possible enhancement of leaf decomposition by means of different nitrogen containing products or mulching of leaves and the resulting reduction of the ascopore potential of Venturia inaequalis. For each treatment 30 scabbed leaves of 'Jonagold' were placed in wire-mesh cages with or without fleece to avoid or allow activity of earthworms, respectively. The leaves were treated as follows: untreated as a control, spraying or addition of: urea (46% N), Siapton (organic liquid fertiliser, 7% N), horn meal (organic fertiliser, 10-14% N), Radivit (decomposition enhancer, 9% N) and slightly rotted manure (0,5% N). All treatments were adjusted to a similar amount of N per m2. In addition leaves in one treatment were mulched. The decomposition of leaves was strongly enhanced by mulching and use of Radivit in both years, irrespective of interference by earthworms. Application of urea enhanced decomposition of leaves only in the first year. In tendency, ascospore production was reduced by all treatments in comparison to the control. The lowest number of ascospores was obtained after mulching of leaves in both years. For all other treatments, the influence of the weather and application/distribution technique are discussed

International Balkan and Near Eastern Social Sciences Congress

Abstract. International Balkan and Near Eastern Social Sciences Congress Series (IBANESS) Congress series are held in different Balkan countries with hosting Universities in Balkan countries. The organization committee includes respected scientists from all over the world. The main aim of the congress is to bring together scientists from Balkan countries in order to disseminate the knowledge and mutual understanding. IBANESS include four meetings in 2017, namely Edirne/Turkey, Russe/Bulgaria, Kırklareli/Turkey and Ohrid/Macedonia..Keywords. Balkan economies, Near Eastern economies, Social sciences.JEL. A10

In-situ Raman study of laser-induced graphene oxidation

We present in-situ Raman measurements of laser-induced oxidation in exfoliated single-layer graphene. By using high-power laser irradiation, we can selectively and in a controlled way initiate the oxidation process and investigate its evolution over time. Our results show that the laser-induced oxidation process is divided into two separate stages, namely tensile strain due to heating and subsequent $p$-type doping due to oxygen binding. We discuss the temporal evolution of the $D/G$-mode ratio during oxidation and explain the unexpected steady decrease of the defect-induced $D$ mode at long irradiation times. Our results provide a deeper understanding of the oxidation process in single-layer graphene and demonstrate the possibility of sub-$\mu$m patterning of graphene by an optical method.Comment: 5 pages, 4 figures [submitted as IWEPNM 2015 conference publication to pss(b)

Approximate Computation of DFT without Performing Any Multiplications: Applications to Radar Signal Processing

In many practical problems it is not necessary to compute the DFT in a perfect manner including some radar problems. In this article a new multiplication free algorithm for approximate computation of the DFT is introduced. All multiplications $(a\times b)$ in DFT are replaced by an operator which computes $sign(a\times b)(|a|+|b|)$. The new transform is especially useful when the signal processing algorithm requires correlations. Ambiguity function in radar signal processing requires high number of multiplications to compute the correlations. This new additive operator is used to decrease the number of multiplications. Simulation examples involving passive radars are presented
