On the Construction of Codes from an Asymptotically Good Tower over F8

In 2002, van der Geer and van der Vlugt gave explicit equations for an asymptotically good tower of curves over the field F8. In this paper, we will present a method for constructing Goppa codes from these curves as well as explicit constructions for the third level of the tower. The approach is to find an associated plane curve for each curve in the tower and then to use the algorithms of Haché and Le Brigand to find the corresponding Goppa codes.

Research of the Acoustic Characteristics of the Bell "Mazepa" of the Sofia Cathedral (Kiev) and their Comparison with Characteristics of Bulgarian Bells

Experimental researches of one of the eldest bells («Mazepa»-see Appendix1) in Ukraine, are considered in the article. The spectra and spectra- time analysis of bell ringing is embodied, main frequencies of oscillation and musical intervals of sounding are determined. Comparative description of bell sounding with the known bells of Russia and Bulgaria is given.

Aszimmetriák az Európai Unión belül (Assimetries within the European Union)

A centrum-periféria kapcsolatok elemzése az Európai Unióra is kiterjeszthető. Az integrációs folyamatban jól elemezhetőek a bourdeiu-i tőkeformák, ezek egymásra történő átváltása, a gazdasági és politikai aszimmetriák kölcsönhatása. E kölcsönös kapcsolatokban továbbra is a gazdasági viszonyok meghatározottsága érvényesül. A világgazdasági válság felszínre hozta a történelmi aszimmetriákat, amelyeket a korábbi neoliberális politikák tovább mélyítettek. Az Unión belüli periferális térségekre a válság különbözőképpen hatott. E hatások semlegesítésére többnyire a megszorító gazdaságpolitikákat alkalmazzák. Továbbra is hiányzik azonban egy, a minőségi s nem mennyiségi szempontokat hangsúlyozó fejlesztési politika. Egy ilyen megközelítés a strukturális, intézményi vonatkozásokat erősítené, s ezzel járulna hozzá a periféria termelési, forgalmi, elosztási képességeinek fokozásához. _____ Analysis of centre-periphery relations can be extended to the European Union as well. The capital forms by Bourdieu, their inter-changeability, mutual effects of economic and political asymmetries could be analysed well in the integration process. In these mutual relations economic relations still play the dominant role. The global economic crisis has brought to the surface historical asymmetries, further aggravated by earlier neo-liberal economic policies. Peripheral regions within the Union have been affected in different ways. In order to neutralise these effects austerity measure have been implemented. However, a development policy, emphasising quality and not only quantitative aspects, is still missing. Such an approach would strengthen structural and institutional elements, further enhancing production, trade, and distribution capabilities of the periphery.

Relatório de Estágio no Hotel Hesperia Tower: Desenvolvimento de uma Checklist de Eventos para a Secção de Conference Concierge

O presente relatório resulta da realização de um Estágio Erasmus no Hotel Hesperia Tower, localizado em Barcelona, integrado no Mestrado de Gestão e Direção Hoteleira na Escola Superior de Turismo e Tecnologia do Mar (ESTM). O estágio teve a duração de 9 meses, com inicio a 16 de Setembro de 2013 a fim a 16 de Junho de 2014 e foi realizado no departamento de restauração, mais precisamente, na função de Conference Concierge. Como objetivos específicos deste relatório, foram definidos: caracterizar o segmento de eventos do hotel; descrever os procedimentos operacionais do departamento de eventos do hotel; descrever, detalhadamente, as funções do Conference Concierge; identificar possíveis falhas nos serviços prestados pelo departamento de eventos do hotel; e desenvolver uma checklist para auxílio do Conference Concierge. A fundamentação teórica abordou os temas de hotelaria de negócios, turismo de negócios e eventos de negócio. O desafio intitulado de Desenvolvimento de uma Checklist para a Função de Conference Concierge do Hotel Hesperia Tower, Barcelona tem, como objetivo geral, propor a implementação de uma lista com as várias tarefas diárias a realizar pelo Conference Concierge durante um evento, visando a qualidade do atendimento prestado pelo departamento de eventos onde o Conference Concierge está inserido.

Molecular hydrogen (H2) mixing ratio and stable isotopic composition (dD) at the Cabauw tall tower in the Netherlands (2008-2012)

Measurements of the stable isotopic composition (dD(H2) or dD) of atmospheric molecular hydrogen (H2) are a useful addition to mixing ratio (X(H2)) measurements for understanding the atmospheric H2 cycle. dD datasets published so far consist mostly of observations at background locations. We complement these with observations from the Cabauw tall tower at the CESAR site, situated in a densely populated region of the Netherlands. Our measurements show a large anthropogenic influence on the local H2 cycle, with frequently occurring pollution events that are characterized by X(H2) values that reach up to 1 ppm and low dD values. An isotopic source signature analysis yields an apparent source signature below -400 per mil, which is much more D-depleted than the fossil fuel combustion source signature commonly used in H2 budget studies. Two diurnal cycles that were sampled at a suburban site near London also show a more D-depleted source signature (-340 per mil), though not as extremely depleted as at Cabauw. The source signature of the Northwest European vehicle fleet may have shifted to somewhat lower values due to changes in vehicle technology and driving conditions. Even so, the surprisingly depleted apparent source signature at Cabauw requires additional explanation; microbial H2 production seems the most likely cause. The Cabauw tower site also allowed us to sample vertical profiles. We found no decrease in (H2) at lower sampling levels (20 and 60m) with respect to higher sampling levels (120 and 200m). There was a significant shift to lower median dD values at the lower levels. This confirms the limited role of soil uptake around Cabauw, and again points to microbial H2 production during an extended growing season, as well as to possible differences in average fossil fuel combustion source signature between the different footprint areas of the sampling levels. So, although knowledge of the background cycle of H2 has improved over the last decade, surprising features come to light when a non-background location is studied, revealing remaining gaps in our understanding.
