Trabajo de Fin de Máster en Internet de las Cosas, Facultad de Informática UCM, Departamento de Arquitectura de Computadores y Automática, Curso 2021/2022.Perderse en un edificio. Frustrante y habitual. Todos nos perdemos en algún momento. La capacidad innata de la orientación nos ayuda a escapar de estas situaciones, usando la percepción del entorno para encontrar pistas que nos permitan reconocer dónde estamos, y a dónde vamos. Mientras que las técnicas de guiado y señalización han avanzado con nuevos dispositivos e ingenios, ofreciendo mapas dinámicos y guiado inteligente, lo de orientarse dentro de los edificios se mantiene de forma bastante estática desde hace tiempo. Este trabajo formula una solución de guiado en interiores con el fin de llegar a un destino y evitar perderse en un entorno desconocido. Para ello, detectando a una persona mediante su smartphone o cualquier dispositivo con bluetooth, se le guiara con señales en pantallas al destino que quiere llegar.To get lost in a building. Frustrating and common. We all get lost at some point. The innate ability to orient ourselves helps us escape these situations, using our perception of our surroun dings to find clues to recognize where we are, and where we are going. While guidance and signaling techniques have advanced with new devices and inventions, offering dynamic maps and intelligent guidance, orientation within buildings has remained fairly static for some time. This paper formulates an indoor guidance solution in order to reach a destination and avoid getting lost in an unfamiliar environment. To do this, detecting a person through your smartphone or any device with bluetooth, you will be guided with signs on screens to the destination you want to reach.Depto. de Arquitectura de Computadores y AutomáticaFac. de InformáticaTRUEunpu

Options to support sustainable trajectories in a rural landscape : drivers, rural processes, and local perceptions in a colombian coffee-growing region

Altres ajuts: Ean UnivesityUnidad de excelencia María de Maeztu CEX2019-000940-MTrajectories of many rural landscapes in Latin America remain unsustainable. Options to support sustainable rural trajectories should be comprehensive and rooted in the interests of rural actors. We selected a municipality in a coffee-growing region in Colombia with an increasing urban- rural nexus to describe interactions between rural processes and their drivers while identifying and contextualising the perceptions of local actors on major constraints and opportunities for more inclusive and sustainable rural trajectories. We described these interactions by combining secondary data on main drivers, agricultural census data, and interviews with different local actors. Changes in population structure, volatility in coffee prices, in-/out-migration, deagrarianisation, and rurbanisation, among others, are reconfiguring the rural trajectories of the study area. Despite not being a major coffee region, farmers in the study area have developed different strategies, including intensification, diversification, replacement or abandonment of coffee production, and commercialisation. The perceptions of local actors and the multiplicity of agricultural households, food/land use systems, rural processes, and drivers described in this study suggest that more sustainable rural transitions need to be supported by inclusive, integrated, and transformative landscape planning approaches that align with local priorities. However, this transformation needs to be accompanied by changes at a systemic level that address the fundamental bottlenecks to real sustainability

Construcción de digital brand awareness en compañías de cannabis legal en Colombia, una revisión teórica del problema a sus potenciales alternativas.

Las restricciones a la publicidad para la industria del cannabis legal suponen uno de los mayores obstáculos que enfrentan estas crecientes industrias en Colombia. Este trabajo busca alternativas encontradas desde la academía al obstáculo que supone dicha restricción para su desarrollo comercial, tiene un alcance documental y académico, donde se pretende encontrar la solución más cercana frente al problema que supone las restricciones a la publicidad en internet para el mercado legal del cannabis. El resultado de este ejercicio será un documento académico de utilidad para la Asociación Colombiana del Cannabis (Asocolcanna), el cual será entregado en las respectivas oficinas de la institución. El objeto de esta investigación se centra en las alternativas del posicionamiento de empresas de cannabis colombiano en motores de búsqueda restrictivos en cuanto a su publicidad, por eso se evaluarán las alternativas hacia la publicidad en los motores de búsqueda que ya han sido catalogados como más efectivos que la alternativa de pagar por ello. Como en el mercado retail, donde la mayor parte del tráfico de usuarios en motores de búsqueda vienen del tráfico orgánico o natural, en vez del publicitado o pago (Bayer, De los Santos y Wildebeest 2015).1.

V2: Integrated management of rainwater for crop-livestock agroecosystems

With mixed crop-livestock systems projected to remain the main providers of food in the coming decades, opportunities exist for smallholders to participate and benefit from emerging crop and livestock markets in the Volta Basin. This project intends to identify, evaluate, adapt, and disseminate best-fit integrated rainwater management strategies (RMS), targeted to different biophysical and socio-economic domains. The integrated RMS are comprised of technological solutions, directed at different components of the agroecosystems, underpinned by enabling institutional and policy environments and linked to market incentives that can drive adoptio

Neanderthal teeth from Lezetxiki (Arrasate, Iberian Peninsula): New insights and reassessment

Objectives We reassess the taxonomic assignment and stratigraphic context of a permanent upper first molar and a permanent lower third premolar recovered from the archeological site of Lezetxiki in the North of the Iberian Peninsula. Materials and Methods We assessed the external and internal morphology of the teeth using qualitative descriptions, crown diameters, dental tissue proportions, and geometric morphometrics. The teeth from Lezetxiki were compared with Middle Pleistocene specimens, Neanderthals, Upper Paleolithic modern humans, and recent modern humans. Results Both teeth were consistent with a Neanderthal classification. The upper first molar shows taurodontism, and its cusp proportions and overall morphology match those of Neanderthals. Geometric morphometric analyses of occlusal anatomy classify this molar as a Neanderthal with a posterior probability of 76%. The lower third premolar, which was originally classified as a lower fourth premolar, also shows a Neanderthal morphology. This premolar is classified as a Neanderthal with a posterior probability of 60%. Discussion These teeth represent the only adult Neanderthal teeth from the Western Pyrenees region found to date. The teeth were found at a stratigraphic level (designated Level III) that marks the transition level from Mousterian to Aurignacian, and are among the most recent Neanderthal remains from the north of the Iberian Peninsula.This work was funded by the Dirección General de Investigación of M.E.C, project number CGL2012-38434-C03-03 and MICINN PID202-1-122355N-B-C32; 2017 SGR 1630 Grup de recerca en Antropologia Biològica (GREAB), 2017 SGR 1040 Social, cultural and biological Evolution during the Pleistocene (StEP), and 2021 SGR 01239 of the Generalitat de Catalunya; and 2019 PFR-URV-91 and 22017 Research Groups.

Development of a Passive Mini-Direct Ethanol Fuel Cell: Effect of Mea Assembly Parameters by Hot Pressure

This paper presents preliminary results on the design, construction and evaluation of a passive mini direct ethanol fuel cell (DEFC), capillary fed with 2 mol l-1 aqueous ethanol, at a rate of 2.03 μL min-1, and air oxygen in the cathode through an air vent. Parameters such as pressure, temperature and time of manufacturing a membrane-electrode assembly (MEA) by hot-pressure were evaluated. As the electrode holder used a 0.25 cm2 carbon tissue which was deposited on the catalytic layer (C. L.) for both the anode (0.8 mg cm-2of PtRu/C) and the cathode (0.8 mg cm -2of Pt/C), Nafi on® 115 membranes were used as the electrolyte. The results show, an average power density of 302 μWcm2 under the best conditions used, a catalytic layer with a Nafi on percentage of 50% at 25 °C. A temperature of 125 °C, a pressure of 49.2 Kg/cm2, and 90 seconds duration were used to obtain the MEA
