Geovisualization of green spaces with augmented reality

The management of green spaces in urban areas requires new techniques and instruments that provide all the information available to people. It is intended to facilitate data-based services to citizens through the use of mobile devices in green spaces, parks and most visited public gardens. The selected area of study has been the Plaza de Oriente (Madrid) and its surroundings. Maps and images from different sources of information have been implemented in this research work.Then we proceeded to develop a database with woodland and existing cultural heritage. Finally, related this information using geolocation and augmented reality system. We have created a system that allows the user to interact with the single orientation of the camera on your mobile device. This application allows efficient use through the integration of mobile devices and the knowledge of the cultural heritage associated with the public space

Metodología de diseño, observación y cálculo de redes geodésicas interiores en túneles de ferrocarril de alta velocidad

El guiado de las Tuneladoras durante su avance debe apoyarse en los puntos determinados inmediatamente detrás de ellas. Conseguir las precisiones requeridas presentaría algunas dificultades en condiciones normales con respecto al exterior, pero en el interior de un túnel se plantean ciertos factores que ensombrecen el panorama. El más importante y difícil de tratar es el de la refracción lateral. El diseño de redes interiores es uno de los principales problemas, desde el punto de vista geodésico y topográfico, el cual tiene unas características tales que todos los textos de topografía de precisión aconsejan evitar. Con estas redes se va guiando la tuneladora y en ningún momento dicha red vuelve a tener comprobación sobre otros puntos de control. A medida que la red va avanzando, las precisiones obtenidas de sus coordenadas van empeorando de forma exponencial. Este trabajo establece una metodología para el diseño de redes planimétricas interiores. ABSTRACT The guiding of TBMs (Tunnel Boring Machines) along their advance must be based on points placed immediately behind them. Achieving good accuracies results would present some difficulties for normal exterior conditions, but inside a tunnel certain factors clouding the outlook arise. The most important and difficult factor to deal with, has to do with lateral refraction. Internal geodetic networks design is one of the more challenging problems from the geodetic and topographic point of view, as the bibliographical review dealing with this subject, advises to avoid this practice. This network allows only guiding the TBM, so that it is not used for further checking or quality control. As the network progresses, the reached coordinate accuracies deteriorate exponentially. This work establishes a methodology for the design of internal horizontal networks

B Lymphocyte as a Target of Bacterial Infections

B lymphocytes are central players in the immune response; canonically, they have been recognized as precursors of antibody-producing cells: plasma cells. Recent findings have shown that the role of B lymphocytes goes far beyond the production of antibodies. There are different subtypes of B lymphocytes with different participations in innate and adaptive responses that include the recognition of the antigen, its processing, and its presentation to T lymphocytes, as well as the production of cytokines that impact and modulate the response toward the pathogen. Traditionally, it has been considered that B lymphocytes do not have phagocytic abilities that allow them to internalize, to process, or even to be infected by bacterial pathogens. The new information has shown that B lymphocytes can be readily infected by bacterial pathogens like Salmonella, Francisella, Moraxella, and Mycobacterium, among others, and respond to those infections. Some of the recent advances on these topics will be presented in this chapter

In vitro characterization of a novel magnetic fibrin-agarose hydrogel for cartilage tissue engineering

The encapsulation of cells into biopolymer matrices enables the preparation of engineered substitute tissues. Here we report the generation of novel 3D magnetic biomaterials by encapsulation of magnetic nanoparticles and human hyaline chondrocytes within fibrin-agarose hydrogels, with potential use as articular hyaline cartilagelike tissues. By rheological measurements we observed that, (i) the incorporation of magnetic nanoparticles resulted in increased values of the storage and loss moduli for the different times of cell culture; and (ii) the incorporation of human hyaline chondrocytes into nonmagnetic and magnetic fibrin-agarose biomaterials produced a control of their swelling capacity in comparison with acellular nonmagnetic and magnetic fibrin-agarose biomaterials. Interestingly, the in vitro viability and proliferation results showed that the inclusion of magnetic nanoparticles did not affect the cytocompatibility of the biomaterials. What is more, immunohistochemistry showed that the inclusion of magnetic nanoparticles did not negatively affect the expression of type II collagen of the human hyaline chondrocytes. Summarizing, our results suggest that the generation of engineered hyaline cartilage-like tissues by using magnetic fibrin-agarose hydrogels is feasible. The resulting artificial tissues combine a stronger and stable mechanical response, with promising in vitro cytocompatibility. Further research would be required to elucidate if for longer culture times additional features typical of the extracellular matrix of cartilage could be expressed by human hyaline chondrocytes within magnetic fibrin-agarose hydrogels.This study was supported by projects FIS2013-41821-R (Plan Nacional de Investigación Científica, Desarrollo e Innovación Tecnológica, Ministerio de Economía, Industria y Competitividad, MINECO Spain, cofunded by Fondo Europeo de Desarrollo Regional, FEDER, European Union), FIS2017-85954-R (Ministerio de Economía, Industria y Competitividad, MINECO, and Agencia Estatal de Investigación, AEI, Spain, cofunded by Fondo Europeo de Desarrollo Regional, FEDER, European Union), and by the Consejería de Salud y Familias, Junta de Andalucía, Spain, Grant SAS CS PI-0257-2017

Tutorial 2.0 on Technical Drawing 3D and Visualization

In recent years, the continuous incorporation of new technologies in the learning process has been an important factor in the educational process (1). The Technical University of Madrid (UPM) promotes educational innovation processes and develops projects related to the improvement of the education quality. The experience that we present fits into the Educational Innovation Project (EIP) of the E.U. of Agricultural Engineering of Madrid. One of the main objectives of the EIP is to Take advantage of the new opportunities offered by the Learning and Knowledge Technologies in order to enrich the educational processes and teaching management (2)

Management and planning of urban trees by mobile mapping system

Countless problems that have arisen in urban woodland, because they don't complete a planning and proper management, arise currently numerous studies to streamline the implementation of sustainable green areas. Based on the sustainable management model, we create a database and use a set of Geographic Information Technology (GIT), in order to solve the current problems of urban woodline

Assessment of Underground Wine Cellars Using Geographic Information Technologies

Geographic information technologies (GIT) are essential to many fields of research, such as the preservation and dissemination of cultural heritage buildings, a category which includes traditional underground wine cellars. This article presents a methodology based on research carried out on this type of rural heritage building. The data were acquired using the following sensors: EDM, total station, close-range photogrammetry and laser scanning, and subsequently processed with a specific software which was verified for each case, in order to obtain a satisfactory graphic representation of these underground wine cellars. Two key aspects of this work are the accuracy of the data processing and the visualization of these traditional constructions. The methodology includes an application for geovisualizing these traditional constructions on mobile devices in order to contribute to raising awareness of this unique heritage
