Basket-Handle Arch and Its Optimum Symmetry Generation as a Structural Element and Keeping the Aesthetic Point of View

The arches were a great advance in construction with respect to the rigid Greek linteled architecture. Its development came from the hand of the great Roman constructions, especially with the semicircular arch. In successive historical periods, different types of arches have been emerging, which in addition to their structural function was taking aesthetic characteristics that are used today to define the architectural style. When, in the construction of a bow, the rise is less than half the springing line, the semicircular arch is no longer used and the segmental arch is used, and then on to another more efficient and aesthetic arch, the basket-handle arch. This study examines the classic geometry of the basket-handle arch also called the three-centered arch. A solution is proposed from a constructive and aesthetic point of view, and this is approached both geometrically and analytically, where the relationship between the radius of the central arch and the radius of the lateral arch is minimized. The solution achieved allows the maximum springing line or clear span to be saved with the minimum rise that preserves the aesthetic point of view, since the horizontal thrust of a bow is greater than the relationship between the springing line of the arch and the rise. This solution has been programmed and the resulting software has made it possible to analyse existing arches in historic buildings or constructions to check if their solutions were close or not from both points of view. Thus, it has been possible to verify that in most of the existing arches analyzed, the proposed solution is reached

The HISTRA digital platform: Research on HIStory of TRAnslation

[EN] HISTRA (HIStory of TRAnslation in Spanish) aims to transfer to an electronic resource a bulky archive of file cards manually compiled by Dr. Santoyo, an expert in the field of Translation History, who registered bibliographical references of Spanish translations of English works from the 16th century until the 1980s. This process has been carried out with the help of the tool entitled Koha-Kobli, an integrated system for library management, free and open source software carried out by the Grupo de Trabajo de las Bibliotecas de la Administración General del Estado. The work methodology guarantees an exhaustive bibliographic account of the references included and normalization of the registers, based on the Reglas de Catalogación, using the international format MARC21. HISTRA constitutes a robust platform for the retrieval of relevant information about translators and translated works, thus contributing to research in translation history, facilitating studies on literary reception of works translated from English into Spanish, authors and translators.S

¿De qué forma puede ser usada la historia de la matemática como herramienta didáctica?

El presente trabajo tiene como objetivo señalar y reflexionar acerca del rol que desempeña la enseñanza de la Historia de la Matemática en el proceso de enseñanza aprendizaje de esta disciplina; puesto que con el estudio de la misma, el profesor puede lograr ampliar el universo cultural de los alumnos, desarrollar hábitos de lectura, perfeccionar habilidades investigativas y hacer acopio de un vocabulario más amplio en la asignatura. Las situaciones históricas se deben ofrecer a los estudiantes, con el objetivo de dejar en ellos no solo el contenido matemático que les presenta, sino también las vivencias emocionales que repercuten en la formación de valores y el agradecimiento a quienes han trabajado en favor de la humanidad

Glottal Source Cepstrum Coefficients Applied to NIST SRE 2010

Through the present paper, a novel feature set for speaker recognition based on glottal estimate information is presented. An iterative algorithm is used to derive the vocal tract and glottal source estimations from speech signal. In order to test the importance of glottal source information in speaker characterization, the novel feature set has been tested in the 2010 NIST Speaker Recognition Evaluation (NIST SRE10). The proposed system uses glottal estimate parameter templates and classical cepstral information to build a model for each speaker involved in the recognition process. ALIZE [1] open-source software has been used to create the GMM models for both background and target speakers. Compared to using mel-frequency cepstrum coefficients (MFCC), the misclassification rate for the NIST SRE 2010 reduced from 29.43% to 27.15% when glottal source features are use

Differentiation of Trichuris species using a morphometric approach

Trichuris trichiura is a nematode considered as the whipworm present in humans and primates. The systematics of the genus Trichuris is complex. Morphological studies of Trichuris isolated from primates and humans conclude that the species infecting these hosts is the same. Furthermore, numerous molecular studies have been carried out so far to discriminate parasite species from humans and Non-Human Primates using molecular techniques, but these studies were not performed in combination with a parallel morphological study. The hypothesised existence of more species of Trichuris in primates opens the possibility to revise the zoonotic potential and host specificity of T. trichiura and other putative new species of whipworms. In the present work, a study of Trichuris Roederer, 1761 (Nematoda:Trichuridae) parasitizing C. g. kikuyensis, P. ursinus, Macaca sylvanus, Pan troglodytes, and Sus scrofa domestica has been carried out using modern morphometric techniques in order to differentiate populations of Trichuris isolated from four species of captive NHP from different geographical regions, and swine, respectively. The results obtained revealed strong support for geometrical morphometrics as a useful tool to differentiate male Trichuris populations. Therefore, morphometrics in combination with other techniques, such as molecular biology analyses, ought to be applied to further the differentiation of male populations. On the other hand, morphometrics applied to female Trichuris species does not seem to contribute new information as all the measurements combinations of obtained from females always showed similar resultsMinistry of Economy,Industry and Competitiveness(CGL2017-83057)FEDER funds, the Junta de Andalucía (BIO-338)V Plan Propio de Investigación of the University of Sevill

Labour market participation rate in the euro area : performance and outlook, a long-term view

Artículo de revistaThis article analyses the trajectory and the main explanatory factors of changes in the labour market participation rate in the euro area in recent decades. First, these changes are compared with the United States, highlighting the extraordinary convergence that has taken place between the two areas owing to the momentum in the European labour market and the declining secular trend on the other side of the Atlantic. Second, the increase in participation in the euro area was led by females, particularly as a result of the higher probability of new cohorts joining the labour market against a background of significant socio-educational changes. In any event, in view of the demographic ageing in progress and the progressive exhaustion of the above-mentioned changes, the focus is on the need for specific policies aiming to raise labour participation of such population groups where there is still room to do so, i.e. older workers, in general, and women in countries where the gender gap is still larg

Applying project-based learning to teach software analytics and best practices in data science

Due to recent industry needs, synergies between data science and software engineering are starting to be present in data science and engineering academic programs. Two synergies are: applying data science to manage the quality of the software (software analytics) and applying software engineering best practices in data science projects to ensure quality attributes such as maintainability and reproducibility. The lack of these synergies on academic programs have been argued to be an educational problem. Hence, it becomes necessary to explore how to teach software analytics and software engineering best practices in data science programs. In this context, we provide hands-on for conducting laboratories applying project-based learning in order to teach software analytics and software engineering best practices to data science students. We aim at improving the software engineering skills of data science students in order to produce software of higher quality by software analytics. We focus in two skills: following a process and software engineering best practices. We apply project-based learning as main teaching methodology to reach the intended outcomes. This teaching experience shows the introduction of project-based learning in a laboratory, where students applied data science and best software engineering practices to analyze and detect improvements in software quality. We carried out a case study in two academic semesters with 63 data science bachelor students. The students found the synergies of the project positive for their learning. In the project, they highlighted both utility of using a CRISP-DM data mining process and best software engineering practices like a software project structure convention applied to a data science project.This paper was partly funded by a teaching innovation project of ICE@UPC-BarcelonaTech (entitled ‘‘Audiovisual and digital material for data engineering, a teaching innovation project with open science’’), and the ‘‘Beatriz Galindo’’ Spanish Program BEA-GAL18/00064.Peer ReviewedPostprint (published version
