Rutalc: aplicación de soporte a viajeros en entornos rurales para Android

This document details the tools and algorithms used for the development of Rutalc, an agricultural tourism oriented application. It is a mobile application aimed at terminals running under the Android operating system. The application allows the user to select the type of sites he wants to visit in a given area or between two specific locations, and provides a set of points that match the selected type of tourism and a series of paths that interconnect the different points of interest regardless of their type. These paths may run either on asphalt, dirt or both types of track, which is chosen by the user. The application operates independently of the availability of the mobile network. It works with maps provided by the OpenStreetMap platform and for viewing a library of third parties is used, which allows the integration of these with Android. Data used are extracted from the maps provided by the above platform. The document details the different technologies used for development, how information is processed in the database to generate the different routes, and the algorithms used to perform this task. Different examples of results obtained with this development are also shown

El turismo sostenible como factor de desarrollo económico en el marco de la Unión Europea

El turismo es uno de los sectores más importantes y en plena expansión de la economía mundial y de la Unión Europea. Muestra de esto son las cifras que alcanza España. Así en 2007, visitaron el país 59,2 millones que significo un volumen de ingresos de 49.946 millones de euros. Pero si bien el turismo es un sector que se presenta como una relevante actividad económica, también es cierto que esta misma actividad puede producir impactos territoriales y medioambientales muy negativos, dañando paradójicamente los mismos recursos que constituyen su principal activo. De esta manera, resulta clave para su futuro desarrollo encontrar soluciones eficaces, con objeto de alcanzar su máxima sostenibilidad. Tal es el caso, como lo veremos, del "turismo sostenible", que constituye un gran reto económico para el futuro desarrollo de la UniónThe tourism industry is one of the most important and in full expansion of the world economy and the European Union. A example of that is the Spain . In 2007, 59,2 millons of people visited this country, representing an income of 49.946 millons euros. But even if the turism's sector constitutes a notable economy activity, is also true that this activity can also produce some negatifs territorial and environmental impacts, damaging paradoxically his principal activ. For its futur development, it's necessary to find efficients solutions, in order to get a maximum sustainibility. This is the case of the "sustainable turism", which constitutes a big economic aim for the futur development of the European Union

Kernel bandwidth estimation for moving object detection in non-stabilized cameras

The evolution of the television market is led by 3DTV technology, and this tendency can accelerate during the next years according to expert forecasts. However, 3DTV delivery by broadcast networks is not currently developed enough, and acts as a bottleneck for the complete deployment of the technology. Thus, increasing interest is dedicated to ste-reo 3DTV formats compatible with current HDTV video equipment and infrastructure, as they may greatly encourage 3D acceptance. In this paper, different subsampling schemes for HDTV compatible transmission of both progressive and interlaced stereo 3DTV are studied and compared. The frequency characteristics and preserved frequency content of each scheme are analyzed, and a simple interpolation filter is specially designed. Finally, the advantages and disadvantages of the different schemes and filters are evaluated through quality testing on several progressive and interlaced video sequences

Producing more food in a sustainable way is possible : biotechnological and sustainable fertilisation as a way to face population growth

The dramatic increase in the world?s population expected in this century will force a proportional increase in agricultural production in order to ensure the food supply. However, society is now demanding new, more sustainable, and environmentally friendly production methods. In order to achieve this sustainable increase, new biotechnological tools such as gene editing or synthetic biology will have to be used, leveraging the knowledge generated by researchers over decades. The soil microbiome is emerging as a powerful biotechnological tool. The beneficial microorganisms harboured in soils promote plant growth by supplying nutrients and producing hormones and secondary metabolites. Thus, these microorganisms will likely be able to help increase agricultural production in a sustainable way

Molybdenum-catalyzed enantioselective sulfoxidation controlled by a nonclassical hydrogen bond between coordinated chiral imidazolium-based dicarboxylate and peroxido ligands

Chiral alkyl aryl sulfoxides were obtained by molybdenum-catalyzed oxidation of alkyl aryl sulfides with hydrogen peroxide as oxidant in mild conditions with high yields and moderate enantioselectivities. The asymmetry is generated by the use of imidazolium-based dicarboxylic compounds, HLR. The in-situ-generated catalyst, a mixture of aqueous [Mo(O)(O2)2(H2O)n] with HLR as chirality inductors, in the presence of [PPh4]Br, was identified as the anionic binuclear complex [PPh4]{[Mo(O)(O2)2(H2O)]2( -LR)}, according to spectroscopic data and Density Functional Theory (DFT) calculations. A nonclassical hydrogen bond between one C–H bond of the alkyl R group of coordinated (LR)- and one oxygen atom of the peroxido ligand was identified as the interaction responsible for the asymmetry in the process. Additionally, the step that governs the enantioselectivity was theoretically analyzed by locating the transition states of the oxido-transfer to PhMeS of model complexes [Mo(O)(O2)2(H2O)( 1-O-LR)]- (R = H, iPr). The DDG6= is ca. 0 kcal mol-1 for R = H, racemic sulfoxide, meanwhile for chiral species the DDG6= of ca. 2 kcal mol-1 favors the formation of (R)-sulfoxide.Junta de Andalucía (Proyecto de Excelencia FQM-7079)Universidad de Sevilla (VI Plan Propio
