Coupling problem in thermal systems simulations

UPCommons - dl., 02/27/2017 - 11:24
Coupling problem in thermal systems simulations González Esteve, Adrià Building energy simulation is playing a key role in building design in order to reduce the energy consumption and, consequently, the CO2 emissions. An object-oriented tool called NEST is used to simulate all the phenomena that appear in a building. In the case of energy and momentum conservation and species transport, the current solver behaves well, but in the case of mass conservation it takes a lot of time to reach a solution. For this reason, in this work, instead of solving the continuity equations explicitly, an implicit method based on the Trust Region algorithm is proposed. Previously, a study of the properties of the model used by NEST-Building software has been done in order to simplify the requirements of the solver. For a building with only 9 rooms the new solver is a thousand times faster than the current method.

MammoApplet: an interactive Java applet tool for manual annotation in medical imaging

UPCommons - dl., 02/27/2017 - 11:12
MammoApplet: an interactive Java applet tool for manual annotation in medical imaging Mata Miquel, Cristian; Oliver Malagelada, Arnau; Torrent, Albert; Martí Bonmatí, Joan Web-based applications in computational medicine have become increasingly important during the last years. The rapid growth of the World Wide Web supposes a new paradigm in the telemedicine and eHealth areas in order to assist and enhance the prevention, diagnosis and treatment of patients. Furthermore, training of radiologists and management of medical databases are also becoming increasingly important issues in the field. In this paper, we present MammoApplet , an interactive Java applet interface designed as a web-based tool. It aims to facilitate the diagnosis of new mammographic cases by providing a set of image processing tools that allow a better visualization of the images, and a set of drawing tools, used to annotate the suspicious regions. Each annotation allows including the attributes considered by the experts when issuing the final diagnosis. The overall set of overlays is stored in a database as XML files associated with the original images. The final goal is to obtain a database of already diagnosed cases for training and enhancing the performance of novice radiologists

Síntesis i caracterització de les fases secundaries d'urani Na4(UO2)(O2)3·12H2O i Ca2(UO2)(O2)3·9H2O

UPCommons - dl., 02/27/2017 - 11:10
Síntesis i caracterització de les fases secundaries d'urani Na4(UO2)(O2)3·12H2O i Ca2(UO2)(O2)3·9H2O Soriano Sánchez, Irene La gestió, tractament i confinament dels residus nuclears avui en dia és un dels problemes mediambientals més importants. La solució internacionalment acceptada com la més segura i viable per dipositar aquest residus radioactius d’alta activitat de forma definitiva ha estat l’emmagatzematge geològic profund. S’espera que un cop transcorregut centenars o milers d’anys les aigües puguin arribar a travessar totes les barreres que composen l’emmagatzematge geològic profund i arribin al combustible nuclear gastat (CNG). Quan l’aigua entri en contacte amb el CNG, en primera instància s’alliberaran els radionúclids més volàtils i solubles. En aquest moment també tindrà lloc la oxidació del U(IV) a U(V), augmentant d’aquesta manera la solubilitat del UO2, contribuint així a la lixiviació del CNG. Durant la lixiviació del CNG, s’espera assolir condicions de saturació de les aigües, degut a la elevada concentració d’urani, formant d’aquesta manera fases sòlides. La composició d’aquestes fases dependria de la composició de les aigües subterrànies i de les reaccions químiques en les proximitats del CNG. Aquestes fases sòlides precipitaran al mateix temps que els radionúclids s’estan lixiviant i, per tant, els sòlids podrien ajudar a controlar l’alliberació de radionúclids en les aigües subterrànies. Així doncs, aquest treball es centrarà en la sinterització i caracterització de tres noves fases d’urani precipitades en aigües alcalines amb elevada concentració de peròxids d’hidrogen. Aquestes tres fases són, Na2(UO2)(O2)3·12(H2O) (designat NaUT), Ca2(UO2)(O2)3·9(H2O) (designat CaUT) i K6[(UO2)(O2)2(OH)]2(H2O)7 (designat KUD). Per a la realització de la seva síntesi es va prendre com a referència l’únic article que fa menció a la seva preparació, “Expanding the Crystal Chemistry of Uranyl Peroxides: Synthesis and Sturctures of Di- and Triperoxodioxouranium (VI) Complexes”. Per fer possible el seu estudi, es van realitzar la síntesis de cadascuna de les fases d’urani i la seva posterior caracterització. Pel que fa la caracterització d’aquestes tres fases d’urani, es van utilitzar cinc tècniques analítiques. L’espectroscòpia Raman-SERS (per l’obtenció d’informació sobre els grups funcionals de cadascuna de les fases), la difracció de raig X (per l’obtenció d’informació més precisa sobre l’estructura cristal·lina de les fases), la microscòpia electrònica d’escombrat (per l’anàlisi de morfologia estructural i composició química qualitativa), la microscòpia electrònica de transmissió (per l’obtenció d’informació sobre l’estructura de la mostra, amorfa o cristal·lina) i el Plasma d'Acoblament inductiu (per l’obtenció d’informació sobre la composició de les fases).

Slope stability in slightly fissured claystones and marls

UPCommons - dv., 02/24/2017 - 20:56
Slope stability in slightly fissured claystones and marls Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè The paper deals with the behavior of some characteristic soft rocks found in the Iberian Peninsula. In geological terms, they belong to Tertiary basins, the Keuper period and the Jurassic-Cretacic transition. The discussion is organized around the following aspects: (a) the intact material and its brittle behavior; (b) the weathering action of atmospheric events; (c) the persistent discontinuities and scale effects; and (d) the modification of strength after failure. In all cases, instability phenomena are addressed in connection with several case histories. Regarding material brittleness and the initial stress state, two cases of first time failures are discussed. Practical implications concerning the selection of operative strength will be given. Field observations of the relevance of weathering and, also, on the rate of weathering, are given for a Weald claystone. Field observations emphasize the importance of sharp transitions between weathered and intact (or slightly weathered) levels. A recent long-term laboratory investigation on the nature of degradation will be summarized. Macroscopic variables such as stiffness and tensile strength have been found to be uniquely predicted by a degradation law in terms of the accumulated plastic deformations. Persistent discontinuities and, in particular, sedimentation planes play a dominant role to explain slope failures not related to the shallow failures, usually associated with weathered profiles. The strength of discontinuities in a Weald formation was investigated by means of tests performed at two scales. Finally, the evolution in time of residual strength induced by chemical actions, associated with groundwater flow, is highlighted in connection with actual field data of unstable slopes. The final publication is available at Springer via http://dx.doi.org/10.1007/s10346-014-0526-5

Real-time model-based video stabilization for microaerial vehicles

UPCommons - dv., 02/24/2017 - 18:11
Real-time model-based video stabilization for microaerial vehicles Aguilar Castillo, Wilbert Geovanny; Angulo Bahón, Cecilio The emerging branch of micro aerial vehicles (MAVs) has attracted a great interest for their indoor navigation capabilities, but they require a high quality video for tele-operated or autonomous tasks. A common problem of on-board video quality is the effect of undesired movements, so different approaches solve it with both mechanical stabilizers or video stabilizer software. Very few video stabilizer algorithms in the literature can be applied in real-time but they do not discriminate at all between intentional movements of the tele-operator and undesired ones. In this paper, a novel technique is introduced for real-time video stabilization with low computational cost, without generating false movements or decreasing the performance of the stabilized video sequence. Our proposal uses a combination of geometric transformations and outliers rejection to obtain a robust inter-frame motion estimation, and a Kalman filter based on an ANN learned model of the MAV that includes the control action for motion intention estimation.

Image restoration using HOS and the Radon transform

UPCommons - dv., 02/24/2017 - 18:05
Image restoration using HOS and the Radon transform Sayrol Clols, Elisa; Chrysostomos, Nikias; Gasull Llampallas, Antoni The authors propose the use of higher-order statistics (HOS) to study the problem of image restoration. They consider images degraded by linear or zero phase blurring point spread functions (PSF) and additive Gaussian noise. The complexity associated with the combination of two-dimensional signal processing and higher-order statistics is reduced by means of the Radon transform. The projection at each angle is an one-dimensional signal that can be processed by any existing 1-D higher-order statistics-based method. They apply two methods that have proven to attain good one-dimensional signal reconstruction, especially in the presence of noise. After the ideal projections have been estimated, the inverse Radon transform gives the restored image. Simulation results are provided.
