Cost index (CI) and take-off mass (TOM) estimation using machine learning algorithms

The Cost Index (CI) and Take-off Mass (TOM) are two parameters that are very important in order to study the preferences on airlines operation. In the same way, these two parameters would allow to predict ground-based trajectories accurately. Nowadays, unfortunately, this information is not shared by the airlines, because this information is confidential as they help to define market strategies of the airline. The objective of this final degree project is to develop and evaluate an algorithm able to estimate CI and TOM from data of a flight trajectory, that could be collected by a conventional antenna (i.e. radar data or ADS-B), by using Machine Learning algorithms. The algorithm should be trained with data from the PEP (Performance Program Airbus). The data will be shaped by thousands of trajectories generated with different ranges of distances, TOM, CI and atmospheric conditions in order to establish the input training data for Machine Learning. Once the algorithm has been generated, to ensure its robustness, it will be tested with data containing noise where the influence of the parameters in the prediction would be evaluated. Finally, it will be validated with new aircraft trajectories from PEP. The ultimate goal of the final degree project is to check and perform the study with real flight data. To realize this, radar data will be obtained from the DDR2 platform of Eurocontrol. With some flights trajectories, we will study the values of CI and TOM used by several airlines with the Machine Learning algorithm previously trained. In conclusion, it has been demonstrated that for CI the most relevant input variable is the Mach Number because it is the most visible evidence given to the time-fuel cost relation. On the other hand, TOM is more related to the distance of the flight and flight levels (FL). When the prediction algorithm is applied to real cases flights, we observed that low-cost airlines and flag carriers use different strategies of CI. Even so, a single airline usually use the same CI for most of their routes, wasting the opportunity to optimize the costs of the route and all the advantages offered by the CI

Evaluation of poly(2-hydroxyethyl methacrylate) gels as drug delivery systems at different pH values

Studies of dynamic and equilibrium swelling, structural characterisation and solute transport in swollen poly(2-hydroxyethyl methacrylate) gels (pHEMA) cross-linked with tripropyleneglycol diacrylate (TPGDA) were done for a wide range of TPGDA concentrations. The influence of the pH on these pHEMA properties was evaluated. In swelling studies it was found that in changing the pH from 6.5 to 12.0, a large increase in swelling occurred, from approximately 48 to 55%, for the lowest concentration of TPGDA (1 mol%), and from 40 to 80% for the highest concentration (10mol%). Fourier transform infrared (FTIR) and differential scanning calorimetry (DSC) measurements were made after the equilibrium swelling of the gels at different pH values, to explain these results. The advantage of using these gels as controlled drug delivery systems is illustrated using salicylic acid (SA) as a model drug. The loading and the release of the SA were made at different pH values and the results obtained showed that it is possible to modulate the hydrogel performance by controlling an external factor, the pH at which the drug loading and release were performed.http://www.sciencedirect.com/science/article/B6T7W-3YMW350-4/1/bd1b81f7d9f216abf72881a42ad0163

Une approche formelle pour la génération d'analyseurs de langages naturels

[Abstract] Un processus d'analyse syntaxique et d'annotation efficace est déterminante dans l'élaboration de structures d'analyse de langages naturels. Ce papier introduit un environnement de programmation permettant l'implémentation du support formel des langages naturels depuis deux points de vue, analyse syntaxique et annotation. Le problème de l'analyse syntaxique se pose dans le domaine de l'analyse de grammaires algébriques sans restrictions, et celui de l'annotation dans le contexte des automates finis non déterministes. L'analyseur syntaxique prends en entrée un texte arbitraire, suivant la structure désignée par une grammaire algébrique. La structure de la forêt partagée résultante est étudiée par rapport à l'optimisation du partage syntaxique, de façon à favoriser l'élimination des ambigüités pendant le processus sémantique. Les automates à états finis sont utilisés comme formalisme opérationnel pour annoter les corpora de façon efficace, spécialement pour les langages autres que l'Anglais, pour lesquels l'analyse morphologique a une relevance accrue. Les deux activités, analyse syntaxique et annotation, sont intégrées dans un même outil, qui a pour nom Galena (pour Generador de Analizadores para Lenguages Naturales), fournissant l'incrémentalité comme fonctionnalité favorisant la réutilisabilité des composantes d'un point de vue génie logiciel.Xunta de Galcia; XUGA10501A9

On-line assessment of comprehension processes

In this paper we describe a new version of a former paper-and-pencil standardized comprehension test called Test of Comprehension Processes (Vidal-Abarca, Gilabert, Martínez, & Sellés, 2007). The new version has been adapted to a computer-based environment based on the moving window technique. It can be used to assess comprehension strategies of students from fifth to tenth grades (11 to 16 years old). Comprehension strategies are registered on-line using reading times and visits to relevant sections of the text during the question-answering process. Data show that the computerbased version draws similar results to those provided by the paper-and-pencil version. In addition, we identify the particular strategies deployed during the question-answering process by high, medium and low [email protected]; [email protected]; [email protected]; [email protected]

El CIDA: 20 años de gestión documental para la investigación en arte contemporáneo

En estos 20 años, el trabajo realizado por el Centro Internacional de Documentación Artística Vicente Aguilera Cerni de Vilafamés (CIDA) ha dado como fruto un fondo documental esencial para conocer el panorama artístico de la segunda mitad del siglo xx. Los documentos cedidos por Vicente Aguilera que dieron origen al CIDA, junto con aquellos cedidos por el MACVAC, otros artistas y críticos de arte, han sido recopilados y gestionados para ponerlos a disposición de los usuarios y facilitar su consulta, convirtiéndose en un recurso para la investigación del arte.In these 20 years, the work done by the CIDA (International Art Documentation Centre Vicente Aguilera Cerni of Vilafamés) has produced as a result a documentary collection essential to the understanding of the art scene of the second half of the twentieth century. The documents that gave rise to the creation of CIDA (donated by Vicente Aguilera),along with the ones transferred from the MACVAC, other artists and art critics, have been compiled and managed in order to make them available to users, thus becoming a resource for art research

Strong coupling between weakly guided semiconductor nanowire modes and an organic dye

The light-matter coupling between electromagnetic modes guided by a semiconductor nanowire and excitonic states of molecules localized in its surrounding media is studied from both classical and quantum perspectives, with the aim of describing the strong-coupling regime. Weakly guided modes (bare photonic modes) are found through a classical analysis, identifying those lowest-order modes presenting large electromagnetic fields spreading outside the nanowire while preserving their robust guided behavior. Experimental fits of the dielectric permittivity of an organic dye that exhibits excitonic states are used for realistic scenarios. A quantum model properly confirms through an avoided mode crossing that the strong-coupling regime can be achieved for this configuration, leading to Rabi splitting values above 100 meV. In addition, it is shown that the coupling strength depends on the fraction of energy spread outside the nanowire, rather than on the mode field localization. These results open up a new avenue towards strong-coupling phenomenology involving propagating modes in nonabsorbing media.The authors acknowledge the Spanish Ministerio de Economía, Industria y Competitividad for financial support through Grants No. MAT2014-53432-C5-5-R, No. FIS2015-69295-C3-2-P, and No. FIS2017-91413-EXP; the María de Maeztu program for Units of Excellence in R&D (MDM-2014-0377); and an FPU Fellowship (D.R.A.) and a Ramón y Cajal grant (J.F.).

Unravelling the genetic basis of simplex Retinitis Pigmentosa cases

Retinitis Pigmentosa (RP) is the most common form of inherited retinal dystrophy (IRD) characterized ultimately by photoreceptors degeneration. Exhibiting great clinical and genetic heterogeneity, RP can be inherited as an autosomal dominant (ad), autosomal recessive (ar) and X-linked (xl) disorder. Although the relative prevalence of each form varies somewhat between populations, a major proportion (41% in Spain) of patients represent simplex cases (sRP) in which the mode of inheritance is unknown. Molecular genetic diagnostic is crucial, but also challenging, for sRP patients because any of the 81 RP genes identified to date may be causative. Herein, we report the use of a customized targeted gene panel consisting of 68 IRD genes for the molecular characterization of 106 sRP cases. The diagnostic rate was 62.26% (66 of 106) with a proportion of clinical refinements of 30.3%, demonstrating the high efficiency of this genomic approach even for clinically ambiguous cases. The high number of patients diagnosed here has allowed us to study in detail the genetic basis of the sRP. The solved sRP cohort is composed of 62.1% of arRP cases, 24.2% of adRP and 13.6% of xlRP, which implies consequences for counselling of patients and families.Union Europea PI15-01648España Ministerio de Economía y Competitividad PI11-02923Junta de Andalucía,Ministerio de Economía, Innovación, Ciencia y Empleo CTS-166
