Optimal Mass Transport on Metric Graphs
2015
We study an optimal mass transport problem between two equal masses on a metric graph where the cost is given by the distance in the graph. To solve this problem we find a Kantorovich potential as the limit of $p$-Laplacian--type problems in the graph where at the vertices we impose zero total flux boundary conditions. In addition, the approximation procedure allows us to find a transport density that encodes how much mass has to be transported through a given point in the graph, and also provides a simple formula of convex optimization for the total cost.
On-line database of voltammetric data of immobilized particles for identifying pigments and minerals in archaeometry, conservation and restoration (E…
2016
[EN] A web-based database of voltammograms is presented for characterizing artists' pigments and corrosion products of ceramic, stone and metal objects by means of the voltammetry of immobilized particles methodology. Description of the website and the database is provided. Voltammograms are, in most cases, accompanied by scanning electron microphotographs, X-ray spectra, infrared spectra acquired in attenuated total reflectance Fourier transform infrared spectroscopy mode (ATR-FTIR) and diffuse reflectance spectra in the UV-Vis-region. For illustrating the usefulness of the database two case studies involving identification of pigments and a case study describing deterioration of an archae…
Classification of diabetes-related retinal diseases using a deep learning approach in optical coherence tomography
2019
Background and objectives: Spectral Domain Optical Coherence Tomography (SD-OCT) is a volumetric imaging technique that allows measuring patterns between layers such as small amounts of fluid. Since 2012, automatic medical image analysis performance has steadily increased through the use of deep learning models that automatically learn relevant features for specific tasks, instead of designing visual features manually. Nevertheless, providing insights and interpretation of the predictions made by the model is still a challenge. This paper describes a deep learning model able to detect medically interpretable information in relevant images from a volume to classify diabetes-related retinal d…
LocalRec 2018 workshop report the second ACM SIGSPATIAL workshop on recommendations for location-based services and social networks * Seattle, Washin…
2019
Driven by technological advances in hardware (positioning systems, environmental sensors), software (standards, tools, network services), and aided by various open movements (open, linked, government data) and the ever-growing mentality of sharing for the greater good (crowdsourcing, crowdfunding, collaborative and volunteered geographic information), the amount of available geo-referenced data has seen dramatic explosion over the past few years. Human activities generate data and traces that are now often transparently annotated with location and contextual information. At the same time, it has become easier than ever to collect and combine rich and diverse information about locations. Exp…
Human Trafficking: The Viscous Link Between Vulnerability and Proximity Violence
2020
The definition of “human trafficking”, adopted by the United Nations Protocol, clearly describes how the international community has outlined the concepts of victim and perpetrator. Despite the definitive effort made by this Protocol, the present chapter seeks to throw light on the fuzzy area existing within the rapport between vulnerability and proximity violence which makes the consensual exploitation of the victim by the trafficker possible as well as making it difficult to outline its contours in the courtrooms.
One size hardly fits all
2013
This paper casts recent accomplishments in the field of Wireless MAC programmability into the emerging Software Defined Networking perspective. We argue that an abstract (but formal) description of the MAC protocol logic in terms of extensible finite state machines appears a convenient and viable data-plane programming compromise for modeling and deploying realistic MAC protocol logics. Our approach is shown to comply with existing control frameworks, and entails the ability to dynamically change the MAC protocol operation based on context and scenario conditions; in essence, move from the traditional idea of "one-size-fits-all" MAC protocol stack to the innovative paradigm of opportunistic…
MAClets: Active MAC Protocols over hard-coded devices
2012
We introduce MAClets, software programs uploaded and executed on-demand over wireless cards, and devised to change the card's real-time medium access control operation. MAClets permit seamless reconfiguration of the MAC stack, so as to adapt it to mutated context and spectrum conditions and perform tailored performance optimizations hardly accountable by an once-for-all protocol stack design. Following traditional active networking principles, MAClets can be directly conveyed within data packets and executed on hard-coded devices acting as virtual MAC machines. Indeed, rather than executing a pre-defined protocol, we envision a new architecture for wireless cards based on a protocol interpr…
Comparison of distance covered in paddle in the serve team according to performance level
2013
Although paddle is the second most practiced sport in Spain, the scientific knowledge about the players' work-load is still very low. The serve is a critical situation because the team has the opportunity to start the point attacking by approaching the net straight after the serve. However, the distance covered by the serve team still has not been studied in padel. OBJECTIVE: This study aimed to analyse the distance covered by the serve team according performance level. It was hypothesized that the server would cover more distance than his partner due to the approach to the net after the serve. Moreover, it also was hypothesized that the difference between serve and partner would be greater…

2015
Darbā tiek aprakstīts uzņēmuma “Meditec” dispečerizācijas programmatūras “Emy” paplašinājums ar jaunu ģeogrāfiskās informācijas sistēmas (ĢIS) moduli, kurš nodrošinās programmu ar iespēju attēlot objektus uz kartes. Darba mērķis ir veikt jau esošās sistēmas papildināšanu ar jaunu funkcionalitāti, kā arī detalizēti aprakstīt jaunās funkcionalitātes darbību un izstrādes procesu Programmatūra tiek izstrādāta kā operētājsistēmas "Windows" tipa lietotne. Programmatūra realizēta, izmantojot C#, Javascript, Microsoft .NET 4.5, Microsoft WPF u.c. tehnoloģijas.
Wireless Power Transfer System Design for E-bikes Application
2019
The present work presents an analysis of Inductive Coupled Power Transfer (ICPT) Systems behaviour applied to electrical bikes. In particular, the study has focused on the design of the coupled coils of this system. In the first part of the work, the theoretical aspects of the wireless power system are handled. In the second part of the work, the inductive features of the coupled windings are analyzed. In order to perform this process, the Ansys Maxwell software has been used, performing 3D simulations. To conclude, the results of the simulations are compared.
