Uncrewed Aerial Vehicles (UAVs) provide a compelling solution for data collection in Internet of Things (IoT) networks due to their mobility and adaptability. However, the line-of-sight dominance in their channels may result in severe interference to ground users during UAV operations. To address this, we present an optimization framework that concurrently optimizes UAV trajectories and transmit powers. Our approach efficiently results in the collection of data from a variety of IoT sensors while (a) minimizing the UAVs flying time and (b) mitigating interference with terrestrial networks. Given the complex nature of such an optimization problem, this paper leverages reinforcement learning, specifically the twin delayed deep deterministic policy gradient algorithm, where a distributed learning algorithm is presented. Experimental results validate the efficacy of our proposed approach, demonstrating its capability to significantly enhance data collection in IoT networks while minimizing UAV flight time and interference with ground user links.

The use of uncrewed aerial vehicles (UAVs) in cell-free networks is poised to unleash a number of new opportunities to further improve wireless networks. However, cell-free UAV networks present major challenges related to the wireless nature of access and fronthaul links. This manuscript studies the uplink of cell-free systems where users connect to UAVs, the latter devices forwarding the information to a processing point through imperfect wireless fronthaul links. Three multiple access alternatives are considered for the fronthaul, namely frequency division multiples access, spatial division multiple access, and combinations thereof. Deterministic equivalent expressions for the spectral efficiency under these fronthaul schemes and minimum mean-square error reception are derived. Then, the optimization subproblems of (a) the 3D deployment of the UAVs, (b) the user transmit powers, and (c) the UAV transmit powers, are investigated. The joint optimization of these subproblems yields superior performance, with the 3D deployment being the main source of improvement.

Recently, the use of uncrewed aerial vehicles (UAVs) in joint sensing and communication applications has received a lot of attention. However, integrating UAVs in current cellular systems presents major challenges related to trajectory optimization and interference management among others. This paper considers a multi-cell network including a UAV, which senses and forwards the sensory data from different events to the central base station. Particularly, the current manuscript covers how to design the UAV's ({i} ) 3D trajectory, (ii) power allocation, and (iii) sensing scheduling such that (a) a set of events are sensed, (b) interference to neighboring cells is kept at bay, and (c) the amount of energy required by the UAV is minimized. The resulting nonconvex optimization problem is tackled through a combination of ({i} ) low-complexity binary optimization, (ii) successive convex approximation, and (iii) the Lagrangian method. Simulation results over a range of various key parameters have shown the merits of our approach, which consumes 33%-200% less energy compared to different benchmarks.

Advancing towards 6G networks emphasizes integrating communication with sensing functionalities, promising unparalleled connectivity, efficiency, and intelligence in forthcoming networks. In this context, uncrewed aerial vehicles (UAVs) emerge as pivotal assets, offering versatile solutions for both communication and sensing tasks. Leveraging their mobility and flexibility, optimizing the UAV deployment or trajectory can enhance the network performance to meet the new demands.Anticipating next-generation 6G networks, traditional cellular architectures' constraints have led to the exploration of new network topologies, including cell-free architectures. These architectures abandon the concept of cell, allowing users to connect to multiple base stations and mitigating the effects of cellular boundaries for fairer scenarios. Combining cell-free architectures with UAVs offers substantial performance gains by leveraging UAV adaptability for dynamic coverage and capacity optimization. To fully leverage this potential, we propose a comprehensive framework for cell-free UAV networks. Initially, UAVs operate as flying base stations within a framework of perfect fronthaul connectivity. This paradigm is extended to accommodate wireless fronthaul scenarios, prompting UAVs to function as flying relays instead of flying base stations.Moreover, UAVs hold significant potential beyond their role in communication. Equipped with sensors and video cameras, UAVs can serve a dual purpose, enabling efficient data collection and sensing tasks. One critical application is wildfire tracking, addressing the pressing need for early detection and monitoring of wildfires. With the escalating frequency and intensity of wildfires globally, efficient wildfire tracking has become imperative for mitigating their devastating impact. Integrating the strengths of cell-free UAV networks with artificial intelligence, our aim is to optimize UAV trajectories to achieve two primary objectives: (i) cover the

The standard treatment in glioblastoma includes maximal safe resection followed by concomitant radiotherapy plus chemotherapy and adjuvant temozolomide. The first follow-up study to evaluate treatment response is performed 1¿month after concomitant treatment, when contrast-enhancing regions may appear that can correspond to true progression or pseudoprogression. We retrospectively evaluated 31 consecutive patients at the first follow-up after concomitant treatment to check whether the metabolic pattern assessed with multivoxel MRS was predictive of treatment response 2¿months later. We extracted the underlying metabolic patterns of the contrast-enhancing regions with a blind-source separation method and mapped them over the reference images. Pattern heterogeneity was calculated using entropy, and association between patterns and outcomes was measured with Cramér's V. We identified three distinct metabolic patterns—proliferative, necrotic, and responsive, which were associated with status 2¿months later. Individually, 70% of the patients showed metabolically heterogeneous patterns in the contrast-enhancing regions. Metabolic heterogeneity was not related to the regions' size and only stable patients were less heterogeneous than the rest. Contrast-enhancing regions are also metabolically heterogeneous 1¿month after concomitant treatment. This could explain the reported difficulty in finding robust pseudoprogression biomarkers., "Funding information: H2020-EU.1.3.

Magnetic sensors are used in many technologies and industries, such as medicine, telecommunications, robotics, the Internet of Things, etc. The sensitivity of these magnetic sensors is a key aspect, as it determines their precision. In this article, we investigate how a thin windmill-like ferromagnetic system can hugely concentrate a magnetic field at its core. A magnetic sensor combined with such a device enhances its sensitivity by a large factor. We describe the different effects that provide this enhancement: the thickness of the device and its unique windmill-like geometry. An expression for the magnetic field in its core is introduced and verified using finite-element calculations. The results show that a high magnetic field concentration is achieved for a low thickness-diameter ratio of the device. Proof-of-concept experiments further demonstrate the significant concentration of the magnetic field when the thickness-diameter ratio is low, reaching levels up to 150 times stronger than the applied field.

Western Eurasia witnessed several large-scale human migrations during the Holocene1,2,3,4,5. Here, to investigate the cross-continental effects of these migrations, we shotgun-sequenced 317 genomes—mainly from the Mesolithic and Neolithic periods—from across northern and western Eurasia. These were imputed alongside published data to obtain diploid genotypes from more than 1,600 ancient humans. Our analyses revealed a ‘great divide’ genomic boundary extending from the Black Sea to the Baltic. Mesolithic hunter-gatherers were highly genetically differentiated east and west of this zone, and the effect of the neolithization was equally disparate. Large-scale ancestry shifts occurred in the west as farming was introduced, including near-total replacement of hunter-gatherers in many areas, whereas no substantial ancestry shifts happened east of the zone during the same period. Similarly, relatedness decreased in the west from the Neolithic transition onwards, whereas, east of the Urals, relatedness remained high until around 4,000 BP, consistent with the persistence of localized groups of hunter-gatherers. The boundary dissolved when Yamnaya-related ancestry spread across western Eurasia around 5,000 BP, resulting in a second major turnover that reached most parts of Europe within a 1,000-year span. The genetic origin and fate of the Yamnaya have remained elusive, but we show that hunter-gatherers from the Middle Don region contributed ancestry to them. Yamnaya groups later admixed with individuals associated with the Globular Amphora culture before expanding into Europe. Similar turnovers occurred in western Siberia, where we report new genomic data from a ‘Neolithic steppe’ cline spanning the Siberian forest steppe to Lake Baikal. These prehistoric migrations had profound and lasting effects on the genetic diversity of Eurasian populations.

‘Translanguaging’ is nowadays an umbrella term referring to either the framework of ‘spontaneous translanguaging’ from the United States or that of ‘pedagogical translanguaging’ from the Basque Country. Both these frameworks propose ways of integrating languages in school, but they adopt very different perspectives on multilingualism, language education and minority languages. This article starts out with a discussion of spontaneous and pedagogical translanguaging as related to their sociolinguistic and educational contexts and a discussion of multilingualism in Sweden. This is followed by a critical review of academic publications on translanguaging published by researchers affiliated to Swedish universities between 2017 – the year in which the distinction between spontaneous and pedagogical translanguaging is featured in the literature – and 2023. The analysis shows that whereas spontaneous translanguaging is highly influential, pedagogical translanguaging generally plays a very understated role. Linked to the current discourse about multilingualism in Sweden, most researchers discuss translanguaging in relation to the social inclusion of students with a foreign background, who are referred to as ‘the multilingual students’, rather than to teaching languages to the whole student population. A central goal of the Swedish educational system, however, is to promote all students' multilingualism by teaching multiple languages, including foreign languages as well as any official or immigrant minority language a student uses at home. We call, therefore, for more attention to pedagogical translanguaging and we claim the importance of adapting translanguaging to the challenges of each society.

Intensive management of arable land reduces earthworm density and diversity. This may impair earthworm-mediated soil functions, such as nutrient mineralization and soil structure formation. To sustain earthworm source populations for re-colonization of cultivated soils, it is therefore important to preserve habitats with high earthworm diversity. Semi-natural grasslands, with a long continuity without soil disturbance, could serve as such earthworm diversity reservoirs. This is particularly important in mixed agricultural landscapes with elements of multiple land uses. Nonetheless, earthworm density and diversity vary greatly among grasslands. To preserve and optimally manage the most suitable grasslands, knowledge about which grassland characteristics best explain earthworm diversity is needed. Additionally, we have a limited picture of earthworm diversity in general, because previous studies have neglected juvenile earthworms and cryptic species. The juvenile fraction commonly comprises the main part of earthworm samples, whereas morphologically inseparable cryptic species account for an unknown fraction. This fraction is of particular importance, as juveniles reflect the local reproductive and regeneration potential of earthworm populations and communities. To determine the full species composition of earthworm communities, we sampled earthworms from 28 semi-natural grasslands in south-central Sweden and identified them to species by DNA barcoding. To test how grassland characteristics explain earthworm density, diversity, and community composition, we measured several characteristics of soils, vegetation, and management of the grasslands, and descriptors of the surrounding landscape. DNA barcoding revealed nearly twice as many species as were identified morphologically. Earthworm densities were higher in grasslands with higher Ellenberg moisture indicator values and lower soil C:N ratios. The diversity and occurrence of many earthworm species was also higher in

Such a bipartite scheme can be described by a staircase: the collection of its minimal points. The complexity of a scheme is the maximal share size relative to the secret size; and the ¿-complexity of an access structure is the best lower bound provided by the entropy method. An access structure is ¿-ideal if it has ¿-complexity 1. Motivated by the abundance of open problems in this area, the main results can be summarized as follows. First, a new characterization of ¿-ideal multipartite access structures is given which offers a straightforward and simple approach to describe ideal bipartite and tripartite access structures. Second, the ¿-complexity is determined for a range of bipartite access structures, including those determined by two points, staircases with equal widths and heights, and staircases with all heights 1. Third, matching linear schemes are presented for some non-ideal cases, including staircases where all heights are 1 and all widths are equal. Finally, finding the Shannon complexity of a bipartite access structure can be considered as a discrete submodular optimization problem. An interesting and intriguing continuous version is defined which might give further insight to the large-scale behavior of these optimization problems., The work of the first author was partially supported by the ERC Advanced Grant ERMiD.

We consider a population organised hierarchically with respect to size in such a way that the growth rate of each individual depends only on the presence of larger individuals. As a concrete example one might think of a forest, in which the incidence of light on a tree (and hence how fast it grows) is affected by shading by taller trees. The classic formulation of a model for such a size-structured population employs a first order quasi-linear partial differential equation equipped with a non-local boundary condition. However, the model can also be formulated as a delay equation, more specifically a scalar renewal equation, for the population birth rate. After discussing the well-posedness of the delay formulation, we analyse how many stationary birth rates the equation can have in terms of the functional parameters of the model. In particular we show that, under reasonable and rather general assumptions, only one stationary birth rate can exist besides the trivial one (associated to the state in which there are no individuals and the population birth rate is zero). We give conditions for this non-trivial stationary birth rate to exist and analyse its stability using the principle of linearised stability for delay equations. Finally, we relate the results to the alternative, partial differential equation formulation of the model.

The location patterns of new working spaces and the factors driving their emergence have been widely studied in Europe. However, research has mainly focused on specific countries and very local areas. We widen this perspective to a regional one and conduct a cross-country study of the location patterns and determinants of today's main new working spaces, specifically coworking spaces that facilitate collaboration and knowledge sharing. Coworking spaces are traditionally associated in the literature with vibrant urban places, but they are also found in non-metropolitan regions. Drawing on a unique data set of coworking space locations in four large European countries (Spain, France, Germany and Poland), we test how demographic, economic, structural, technological and accessibility-related determinants affect the location of these spaces. We then investigate whether the identified determinants vary between metropolitan and non-metropolitan and between countries, controlling for spatial effects.

The picaresque genre and the motif of the false alchemist in particular are fields of study that are relevant in the pursuit of a better understanding of alchemy as it appears in the literature of the sixteenth and seventeenth centuries. This article focuses on Vicente Espinelʼs Vida del escudero Marcos de Obregón (1618). I analyse the representation of a false alchemist and the persuasive strategies Mar-cos de Obregón uses to carry out his deception. I also examine the origin and evolution of the motif of the false alchemist, the different aspects and authorities of alchemy, and the way Espinel combines and employs these. The aim is to broaden the study of alchemy at the beginning of the seventeenth century, a time of great activity in Spain and Europe, El género picaresco y, en particular, el tópico del falso alquimista es un campo de estudio relevante para entender mejor la presencia de la alquimia en la literatura de los siglos XVI y XVII. Este artículo se centra en la Vida del escudero Marcos de Obregón (1618) de Vicente Espinel. Se examina la representación del alquimista embaucador, así como las estrategias persuasivas de las que se sirve para llevar a cabo el engaño. Se incide en el origen y evolución del tópico del falso alquimista, vertientes y autoridades de la alquimia y cómo Espinel combina y emplea estos elementos. Con ello se pretende ampliar el estudio de la alquimia a principios del siglo XVII, momento de gran actividad de esta disciplina en España y Europa

This paper investigates the maximization of data harvested by an uncrewed aerial vehicle (UAV) that supports Internet of Things (IoT) deployment scenarios. The novelty of the paper is that we study the feasibility of battery-free UAV and IoT device deployment where the UAV is powered by a ground laser source, and the IoT devices are powered by a power beacon via bistatic backscattering. We aim to optimize the UAV trajectory while minimizing the laser energy consumption throughout the entire flight by tuning the laser power and the power beacon radiated temporal power profiles. Upon considering an unspecified flying time, we adopt path discretization and resort to the single-block successive convex approximation (SCA) to solve the data collection maximization problem. In addition to considering the UAV dynamics and power budget, two novel SCA-compatible bounds are introduced for the product of positive mixed convex/concave functions. Finally, the simulation results show that the proposed algorithm increases the data collected under different operation conditions by approximately 90%.

Energy prices are of great concern for homeowners and companies, and the implementation of energy efficiency measures has gained importance in recent years as means of mitigating these costs. Energy surveys are useful to analyze and tackle energy inefficiencies, with a focus on the primary issues and the identification of solutions. The objective of this project was to conduct an energy survey of a 1971 villa in Älvkarleby with the aim of identifying the main contributors to energy losses and proposing measures through a quantitative approach. This involved collecting data from the rooms, manual calculations, and the use of a simulation model of the dwelling. Results show that the primary sources of energy loss in the dwelling are the envelope components, particularly the basement walls and windows. While these issues should be addressed, both options are not economically viable in a 15-year period. However, the installation of a ground source heat pump (GSHP) and photovoltaic (PV) panels yielded a net profit over a 15-year period. The implementation of these systems resulted in an annual saving of 13 005 SEK. Moreover, the final use of electricity from the grid for heating purposes is 6.2 MWh/year, which represents a reduction of almost 76 % compared to the previous purchased energy., Outgoing

El objetivo principal de este proyecto es el cálculo y diseño de los distintos elementos de un brazo robótico de 3 grados de libertad, el cual va a trabajar sobre una plataforma robótica móvil. Para ello se van a realizar distintas simulaciones y análisis con el software PTC Creo, con los que se podrá comprobar si los elementos soportan los esfuerzos del modelo. Como se podrá ver, los elementos estructurales están sobredimensionados y habría que reducir el peso de todo el conjunto. En cuanto a los elementos mecánicos encargados de la transmisión de cada articulación, se va a realizar un cálculo convencional de cada uno, con los conocimientos obtenidos durante el máster. Por otra parte, se va a utilizar SolidWorks para el modelado 3D y los planos de fabricación de los componentes. Otro de los objetivos de este proyecto es realizar un análisis económico, para comprobar el coste de un proyecto teórico realizado por un ingeniero y el estudio del impacto ambiental que puede tener un proyecto de este calibre. Para finalizar se va a realizar un plan de igualdad en el que se expone los puntos a mejorar en cuanto a la equidad en el mundo de la ingeniería y una lista de soluciones para poder avanzar en el camino de la igualdad entre todas las personas., The main objective of this project is the calculation and design of various elements of a 3- degree-of-freedom robotic arm, which will operate on a mobile robotic platform. To achieve this, different simulations and analyses will be conducted using PTC Creo software, allowing verification of whether the elements can withstand the model's stresses. As seen, the structural elements are oversized, and it would be necessary to reduce the weight of the entire assembly. Regarding the mechanical elements responsible for transmitting each joint, a conventional calculation for each one will be performed using the knowledge acquired during the master's program. Additionally, SolidWorks will be employed for the 3D modeling and manufacturing drawings of the components. Another objective of this project is to conduct an economic analysis to assess the cost of a theoretical project carried out by an engineer and to study the environmental impact that a project of this magnitude may have. Finally, an equality plan will be developed, outlining areas for improvement regarding equity in the field of engineering and proposing a list of solutions to progress towards equality for all individuals.

Examinant "des de l’espai” Montcada i Reixac es poden identificar un gran nombre de cicatrius que, amb el pas del temps, s’han originat en la geomorfologia del propi municipi. Fruit del passat d’extracció minera, aquestes es tradueixen en un procés de modificació topogràfica de desmunts i terraplenats, una depressió orogràfica que acaba traduint-se en una transfiguració del paisatge. La pedrera esgotada de Can Rovira va arribar al seu límit d’explotació el 2010, any en què va cessar l’activitat d’extracció minera. A dia d’avui, i des del seu tancament, resta a l’espera de l’aprovació d’un projecte de re-naturalització. Com a contra resposta a la ineficàcia generalitzada dels processos de renaturalització i reactivació es projecta un META-Park en què artifici i natura conviuen simultàniament.

Concloent, l'estudi no sols evidencia com l'estandardització pot ser un vehicle per a la millora contínua en la cadena de subministrament de tecnologies avançades, sinó que també destaca el potencial d'aquestes pràctiques per a instaurar un canvi significatiu en la fabricació d'impressores 3D de metalls, apuntant cap a un futur on la sostenibilitat i l'eficiència són eixos centrals de la innovació tecnològica.

In this paper, a state-space model of a metal hydride tank is formulated and analyzed in detail. Firstly, a three-dimensional state-space model of the metal hydride tank is simplified by assuming that the tank temperature can be measured. Secondly, the model is completed with a pipe model, which allows to compute the input flow from the pipe pressure that can be easily measured. The proposed model solves the problem that the conventional metal hydride tank models usually take the mass flow rate as input and ignore the pressure as system input. Thirdly, the first-order trajectory sensitivity analysis method is adopted to determine the sensitivity of selected unknown parameters. Latter, the particle swarm optimization algorithm is used to estimate the unknown model parameters from experimental data. Finally, a comparison between experimental data and simulation results demonstrates that the proposed model can reflect the dynamic characteristics of the metal hydride tank., This work is part of the Project MAFALDA (PID2021-126001OB-C31 funded by MCIN/ AEI /10.13039/50110001 1033 and by “ERDF A way of making Europe”) and Project MASHED (TED2021-129927B-I00 funded by MCIN/AEI /10.13039/501100011033 and by the “European Union Next GenerationEU/PRTR”).

To remove particles from entering the engine or Environmental Control System (ECS), an Inertial Particle Separator (IPS) can be situated in the intake. In IPS, a rapid change in flow direction is induced, and particles separate from the core outlet because of their inertia. Small particles with a low Stokes number (St) follow the flow and often enter the core outlet, while the large particles with a high St are thrown into the scavenge by their high inertia. Accurately capturing the unsteadiness of the fluid is crucial, especially with low scavenge mass flow fraction for the particles with low St. The numerical simulation of the compressible flow is validated here, implementing the 3D Improved Delayed Detached Eddy Simulation (IDDES) and the Reynolds-averaged Navier-Stokes (RANS) methods against experimental data. It is shown that the IDDES method can capture correctly the unsteadiness of the flow. After validation of the fluid phase, the particle separation efficiency was studied for different particle diameters using these turbulence numerical methods along with three different ambient temperatures: standard, hot, and cold. The separation efficiency values were in agreement with the experimental data., Linda Bahramian acknowledges the financial support from the Secretariat of Universities and Research of the Generalitat de Catalunya and the European Social Fund, FI AGAUR Grant (2019 FI B 01205) and the UPC-Santander Grant.

The physics and modeling of air ejectors in on- and off-design conditions have been extensively addressed in the past, reaching a good level of maturity. However, to achieve a robust model at system scale integrating an ejector, there is a need for developing 0D models suitable to tackle abnormal functioning modes, such as cases where the ejector works in subsonic conditions, reverse flows, or closed ports. Based on state-of-the-art models, a new 0D model has been built in the current work, where proper subroutine implementations allow covering normal and abnormal operations of convergent nozzle ejectors. The current research also focuses on understanding the physical behavior of air ejectors for aeronautical applications. In this regard, CFD-RANS simulations are used to perform model verification and calibration as well as to gain knowledge of the whole operational envelope. The regimes reproduced by the 0D model, and validated by CFD, cover the normal operating mode with different choking regimes, the occurrence of a subsonic primary flow, and the closed secondary port case. Additional cases are run to assess other features of the ejector behavior, such as the influence of geometrical properties on the choking mechanism and the impact of thermal effects., Peer Reviewed, Postprint (published version)

The aim of this work is to investigate in-silico the biomechanical effects of a proximal fibular osteotomy (PFO) on a knee joint with different varus/valgus deformities on the progression of knee osteoarthritis (KOA). A finite element analysis (FEA) of a human lower extremity consisting of the femoral, tibial and fibular bones and the cartilage connecting them was designed. The FEA was performed in a static standing primitive position to determine the contact pressure (CP) distribution and the location of the center of pressure (CoP). The analysis examined the relationship between these factors and the degree of deformation of the hip-knee angle in the baseline condition. The results suggested that PFO could be a simple and effective surgical treatment for patients with associated genu varum. This work also reported that a possible CP homogenization and a CoP correction can be achieved for medial varus deformities after PFO. However, it reduced its effectiveness for tibial origin valgus misalignment and worsened in cases of femoral valgus misalignment., This work is supported by the Serra Húnter program (Generalitat de Catalunya) and the Autonomous University of Nuevo León., Peer Reviewed, Postprint (published version)

“La realidad arquitectónica sólo puede tratarse de que un edificio me conmueva o no” Peter Zumthor. Tras esta simple cita de uno de los arquitectos más reconocidos del actual panorama internacional se desarrolla mi trabajo. La primera vez que escuché la filosofía de Zumthor a la hora de desarrollar sus edificios me pareció increíble la simplicidad con la que lo explicaba. Un arquitecto de su talla lo hacía tan comprensible que me llamó la atención y decidí estudiar su obra. El desarrollo de este trabajo no deja de ser una excusa más para aprender sobre él. En el momento de iniciar no tenía claro como hacerlo, hasta que investigando sobre muchos de sus proyectos me fijé en un denominador común en todos ellos, los dibujos. Esos dibujos iniciales transmitían con fuerza las ideas principales de cada proyecto y fue a partir de ahí que decidí desarrollar mi trabajo. Cruzando la filosofía arquitectónica expuesta en una conferencia con los dibujos de la práctica profesional. Y a partir de ahí ver a que conclusiones se pueden llegar sobre la obra de Zumthor, si ha habido continuidad en su obra, si ha habido variaciones con el tiempo. Es decir, este trabajo va encaminado a entender un lenguaje arquitectónico específico y ver su evolución y sus distintas facetas según el contexto de cada proyecto.

Radiation therapy involves delivering a high dose (energy of absorbed radiation per unit mass) to a target volume within the patient. Ionizing radiation is used for penetrating the tumor tissue, causing its the death and eliminating also the cancerous cells surrounding the target. When per- formed, the aim is to minimize the impact on healthy organs by reducing the absorbed doses in their tissues. In the case of external radiation therapy, this is achieved using particle accelerators that target the affected area and direct the radiation using collimators. Before radiation therapy treatment can be administered to the patient, a specific quality control process must be conducted to ensure that the accelerator behaves appropriately according to a designed plan, from which the dose distribution to be administered to the patient’s tissues has been calculated. In addition to verifying critical design parameters of the radiotherapy plan for the accelerator, measurements are taken on phantoms with detectors to verify that the admin- istered dose distribution is within acceptable tolerances. When tumors are small, the volumes that need to receive high doses are small as well, thus requiring the use of radiation beams with very small open collimator apertures. This results in the formation of small radiation fields, which present challenges for measurement, as precision dose delivery to the target is desired and they exhibit dose profiles with very abrupt changes. Therefore, detectors of small volume concentrated in a very small region are required. In this master’s thesis, the behavior of two measurement devices, the SRS MapCHECK and the ArcCHECK (both from Sun Nuclear), has been studied. These devices feature semiconductor detectors and have been specifically designed to perform dose distribution measurements in pre-treatment verifications. The study was conducted by evaluating the gamma passing rates in three scenarios using the SRS MapCHECK and GAFChromic EBT-XD radiogra

Due to its high power density, the aviation sector is pushing towards its electrification by designing new propulsion systems based on cryogenic liquid hydrogen (LH2). From an engineering point of view, the efficient design of tanks constitutes one of the main challenges. They must guarantee efficient isolation of the hydrogen to avoid its evaporation and, at the same time, ensure reasonable weight and dimensions. Using numerical simulations is fundamental for studying heat transfer between the external environment and the liquid fuel. This work focuses on the simulation of multiphase liquid-gas flow to analyze the tank pressurization as a function of different external heat fluxes. A commercial CFD software is used to perform simulations. VOF simulations with the Lee mass transfer model are employed, and some critical numerical parameters are analyzed to provide information on the optimal values., The project H2ELIOS is supported by the Clean Aviation Joint Undertaking and its members.

En este trabajo se estudian las infraestructuras del agua de cuatro ciudades desde una aproximación metodológica multiescalar. La investigación toma como punto de partida la noción del ciclo del agua y la aproximación a las tecnologías y las técnicas tradicionales en el manejo del agua. Desde la revolución industrial, las ciudades han descartado el ciclo hídrico dentro de sus redes de suministro de agua. Es por esto que este trabajo se enfoca en el estudio de los dispositivos hidráulicos precursores a los del sistema de agua a presión. Para abordar el amplio catálogo de elementos que forman los infinitos sistemas de suministro y regulación del agua haría falta un estudio mucho más extenso y profundo. Por lo tanto, se plantea el inicio de un atlante a través de la lectura de cuatro modelos ejemplares de los cuales cada uno ocupa un capítulo. Para construir el atlante se ha elaborado una síntesis de la investigación bibliográfica de cada caso -sustancial para elaborar y explicar las representaciones del atlante- que se ha añadido al final del trabajo en forma de anexos. (1) El primer capítulo se centra en el modelo de acueductos en la ciudad de Roma durante el imperio romano y también en la reutilización de este circuito durante los siglos de la Roma barroca y renacentista. (2) El segundo capítulo aborda el modelo de los qanats en Yazd, una ciudad-oasis en el centro de Irán. (3) El tercer capítulo se sitúa en la red de abastecimiento de Barcelona con el Rec Comtal desde la Edad Media y la red municipal que traía el agua desde Collserola hasta el sistema de fuentes de la ciudad. (4) Por último se presenta el caso de Gujarat, una región al norte de la India que antes de la moderna explotación masiva de pozos y bombas, se abastecía de agua a través de sus característicos stepwells o cisternas escalonadas.

El riu Tormes al llarg del seu curs per la capçalera de la conca, des del seu naixement a la serra de Gredos fins l’embasament de San Fernando, té un règim de cabals molt variat, amb grans crescudes, avingudes ordinàries y durs estiatges. Això implica que estigui sotmès a episodis periòdics de gran mobilitat de sediments. Aquesta singularitat del riu Tormes en el seu tram alt és coneguda per l’administració competent que ha encarregat la realització d’un estudi per a la caracterització i estimació del transport sòlid amb origen a la llera que es produeix a la capçalera de la conca fins el embasament de San Fernando. Dintre de l’àmbit d’estudi mencionat es troba un delta interior de dimensions notables en la confluència del Tormes amb el seu tributari Corneja. Es creu que per la seva extensió pot causar una interferència amb la dinàmica del transport de sediments del Tormes, un riu de graves, i del Corneja, un riu de sorres. El present treball estudia el control que exerceix el delta sobre el subministrament de sediment cap a aigües avall mitjançant la modulació del transport sòlid procedent del Tormes i el Corneja. Desprès de realitzar l’estudi es va trobar que la forma en que interfereix el delta en el transport sòlid depèn dels cabals del Tormes i el Corneja. En condiciones de cabals ordinaris el delta actua com un embornal del cabal sòlid de fons provinent del Tormes, es a dir, que retè el material transportat pel Tormes des de aigües amunt. En canvi, amb cabals extraordinaris, en crescudes, actua com una font de material proporcionant sediment al tram d’aigües avall. Per altra banda, la interferència que causa el delta sobre el material transportat pel Corneja es molt menor. Únicament, en crescudes ordinàries en que el delta queda parcialment inundat retindria part de les fraccions granulomètriques més fines transportades pel Corneja., El río Tormes a lo largo de su curso por la cabecera de la cuenca, desde su nacimiento en la Sierra de Gredos hasta el embalse de San Fernando, tiene un régimen de caudales muy variado, con grandes crecidas, avenidas ordinarias y duros estiajes. Esto conlleva que esté sometido a episodios periódicos de gran movilidad de sedimentos. Esta singularidad del río Tormes en su tramo alto es conocida por la administración competente que ha encargado la realización de un estudio para la caracterización y estimación del transporte sólido con origen en el cauce que se produce en la cabecera de la cuenca hasta el embalse de San Fernando. Dentro del ámbito de estudio mencionado se halla un delta interior de dimensiones notables en la confluencia del Tormes con su tributario Corneja. Se cree que por su extensión el delta puede causar una interferencia en la dinámica del transporte de sedimentos del Tormes, un río de gravas, y del Corneja, un río de arenas. El presente trabajo estudia el control que ejerce el delta sobre el suministro de sedimento hacia aguas abajo a través de la modulación del transporte sólido procedente del Tormes y el Corneja. Tras realizar el estudio se encontró que la manera en que interfiere el delta en el transporte sólido depende de los caudales del Tormes y el Corneja. En condiciones de caudales ordinarios el delta actúa como un sumidero del caudal sólido de fondo proveniente del Tormes, es decir, que retiene el material transportado por el Tormes desde aguas arriba. En cambio, con caudales extraordinarios, en crecidas, actúa como una fuente de material proporcionando sedimentos al tramo de aguas abajo. Por otro lado, la interferencia que causa el delta sobre el material transportado por el Corneja es mucho menor. Únicamente, en crecidas ordinarias en que el delta queda parcialmente anegado retendría parte de las fracciones granulométricas más finas transportadas por el Corneja., The course of the Tormes River, from headwaters Sierra de Gredos down to the San Fernando reservoir, has a very varied flow regime, with large flood events, ordinary floods and severe low flows. As a result, the Tormes River is subjected to periodic high sediment mobility episodes. The singularity of the Tormes sediment transport regimen, especially in its uppermost reaches is well known by the water authority. This is the reason for CHD has commissioned a study to UPC aimed at characterizing and estimating the bed-load transport in those reaches from the headwaters down to the San Fernando reservoir (with a drainage area of 1500 km2, approximately). Within the aforementioned study reach, few kilometers upstream of the reservoir there is an inland delta of considerable size, in the order of 19 ha, at the confluence of the Tormes and one of its tributary, the Corneja River. It is believed that, due to the dimensions of the delta, may interfere with the sediment supplied from the upper Tormes, a gravel-bed river, and with that coming from the Corneja River, a sandy bed river. The present work studies the control exerted by the delta on sediment supply from Tormes and Corneja rivers to downstream reaches. The study has found the delta interferes with the sediment supplied from both Tormes and Corneja rivers depending on the flows conditions: magnitude and relative distribution. At ordinary flows conditions, the delta plays the role of a sink for bed-load transport from the Tormes, i.e. it contributes to stall sediment transport upper Tormes reaches. However, during extraordinary flows events, i.e. during floods, the delta exerts as a source for lower reaches, to which it interference is caused by the delta as far as the material supplied by the Corneja is concerned River: only at ordinary floods events, when the delta is just partially flooded, the delta contribute to accumulate part of the finer fractions transported by the Corneja.

El present treball té com a objectiu dotar de recursos al professorat de tecnologia per poder donar compliment al nou Decret d'Educació pel que fa a l'ensenyament de la programació i la robòtica als instituts de Catalunya. S'utilitzarà la marca LEGO per familiaritzar als estudiants en uns camps molt concrets de la tecnologia, com els engranatges, els sensors i els actuadors, analitzant les seves característiques i possibilitats. Al mateix temps s'iniciarà als estudiants en el món de la programació per blocs, que en aquest cas tindrà la finalitat de controlar els mecanismes construïts. Es proposaran diverses situacions d'aprenentatge en què s'utilitzaran els diferents components analitzats, de manera que els estudiants puguin relacionar el component teòric de l'aprenentatge amb una part pràctica on experimentaran el funcionament real dels mecanismes treballats. S'aposta per l'ús de material de la marca LEGO per dos motius: en primer lloc, la seva divisió LEGO Education disposa de sets molt específics i complets per l'ensenyament, fet que fa molt fàcil el treball amb el seu material a l'aula. En segon lloc, fer servir una marca tan coneguda pel seu vessant lúdic la converteix en una metodologia estimulant pels alumnes.

This master thesis proposes the research and development of a CubeSat type lightweight satellite structure. The study is driven by the goal of providing greater accessibility to space research for small organizations such as educational institutions. Three different models have been designed with CATIA V5 software: a commercial structure (Pumpkin model), a theoretical structure (Hexagon model) and the structure proposed in the thesis, the Rhombus model, which presents two different versions. A study of the different structural materials has been carried out; on the one hand, it has been considered the Al5052-H32, an aluminum of the 5xxx series which suffers little reduction of its mechanical properties against welding. On the other hand, four composite materials have been analyzed and compared to verify their viability in the fabrication of this type of structures. The models have been subjected to a series of analyses, consisting of Static Analysis and Frequency Analysis, in order to study their performances for two configurations (with and without internal payload) and four cases of gravity loads. The displacements and the Von Mises Stress for each case of study, as well as the natural frequency modes, were obtained through SolidWorks software. An aluminum structure 14% lighter than the commercial model has been obtained, capable of bearing 15 g-loads on the three main axes with an internal payload of up to 1.5 kg. As for the composite structure, the Windform XT2.0 material has performed successfully under the same conditions, achieving a 65% reduction in mass. Regarding natural frequency modes, both the aluminum and the Windform XT2.0 Rhombus models have been proven to fulfill the frequency requirements of the Vega launcher

The Sansalvador villa, the first project exclusively designed by Josep Maria Jujol in Barcelona, is a unique architectural complex that piques curiosity about its origins and conception. Its incomplete state, limited documentation, and blend of modernist and organic elements contribute to its exceptional nature. This article delves into its history and conceptualization by examining original documents and conducting a detailed photogrammetric survey of the built architectural complex as it is today. By overlaying new planimetry derived from fieldwork onto the original plans, certain peculiarities, discrepancies, and unforeseen changes emerge, shedding light on Jujol’s creative process. The Sansalvador villa reveals the profound connection between the project and its surroundings, showcasing Jujol’s keen awareness of the site’s pre-existing conditions. His architecture is defined by a critical approach to these conditions, integrating them as essential elements in defining the project’s character, Peer Reviewed, Postprint (published version)

In this paper, we discuss the requirements and technical challenges within the EHEM project, Enhancement of Heritage Experiences: The Middle Ages, an ongoing research program for the acquisition, analysis, documentation, interpretation, digital restoration, and communication of medieval artistic heritage. The project involves multidisciplinary teams comprising art historians and visual computing experts. Despite the vast literature on digital 3D models in support of Cultural Heritage, the field is so rich and diverse that specific projects often imply distinct, unique requirements which often challenge the computational technologies and suggest new research opportunities. As good representatives of such diversity, we describe the three monuments that serve as test cases for the project, all of them with a rich history of architecture and paintings. We discuss the art historians’ view of how digital models can support their research, the expertise and technological solutions adopted so far, as well as the technical challenges in multiple areas spanning geometry and appearance acquisition, color analysis and digital restitution, as well as the representation of the profound transformations due to the alterations suffered over the centuries., The EHEM project was approved in the JPI Cultural Heritage Conservation, Protection, and Use (0127) call in 2020.
