Scribe ergo quæ vidisti et quæ sunt et quæ oportet fieri post hæc
2018
Pasado, presente y futuro se dan cita en el fragmento del Apocalipsis. El pasaje mencionado constituye una invitación a reflexionar sobre el pasado, el presente y el futuro de una persona, de una institución o de una colectividad de cualquier terreno de especialización disciplinar en un momento concreto de su trayectoria en el que se pretende escrutar, valorar las formas cognoscitivas pretéritas y, con ellas, se aspira a redefinir el futuro de la investigación. En esta ocasión me propongo aplicarlo a los estudios relacionados con los testimonios escritos en su pluralidad de manifestaciones medievales.
“Waiting for the Bass to Drop”: Correlations Between Intense Emotional Experiences and Production Techniques in Build-up and Drop Sections of Electro…
2014
This study investigates the correlations between theories of intense emotional experiences and production techniques used in the electronic dance music (EDM) sections “build-up” and “drop”, which are designed to build tension and create a heightened emotional intensity among clubbers. This is done by descriptive and interpretive music analysis, where spectrograms and a schematic model visually represent the dominant production techniques. Through a theoretical framework consisting of musical expectancy and gravity, the analysis suggests that i) extensive use of uplifters, ii) the “drum roll effect”, iii) large frequency changes, iv) removal and reintroduction of bass and bass drum and v) a …
High Performance 3D PET Reconstruction Using Spherical Basis Functions on a Polar Grid
2011
Statistical iterative methods are a widely used method of image reconstruction in emission tomography. Traditionally, the image space is modelled as a combination of cubic voxels as a matter of simplicity. After reconstruction, images are routinely filtered to reduce statistical noise at the cost of spatial resolution degradation. An alternative to produce lower noise during reconstruction is to model the image space with spherical basis functions. These basis functions overlap in space producing a significantly large number of non-zero elements in the system response matrix (SRM) to store, which additionally leads to long reconstruction times. These two problems are partly overcome by expl…
The factorization method for electrical impedance tomography data from a new planar device.
2006
We present numerical results for two reconstruction methods for a new planar electrical impedance tomography device. This prototype allows noninvasive medical imaging techniques if only one side of a patient is accessible for electric measurements. The two reconstruction methods have different properties: one is a linearization-type method that allows quantitative reconstructions; the other one, that is, the factorization method, is a qualitative one, and is designed to detect anomalies within the body.
El Discurso del profesorado de educación musical en la innovación educativa con tic: posicionamientos en la evaluación del software tactus.
2014
This paper presents teachers positioning analysis around the assessment of ad hoc software designed for learning musical rhythm called “Tactus”. The main objective is to study the teachers speeches and opinions in software assessment, which is built through the speeches analysis (n = 115) in 8 focus groups, with a descriptive model of 5 clusters. The study gives us a diverse, varied and a full picture in educational software evaluation trough teachers’ discourses analysis. En este estudio empírico analizamos los discursos y posicionamientos del profesorado en torno a la evaluación de un software diseñado ad hoc, para el aprendizaje del ritmo musical denominado Tactus. El objetivo de investi…
Approaching electrical tomography
2009
A general approach to electrical tomography is here described, based on the distribution of the experimental data to the set of voxels in which the subsoil has been divided. This approach utilizes the sensitivity coefficients as factors of the convolution procedure to execute the back projection of the data, to obtain the 3D pictures of the subsoil. A subsequent probabilistic filtering technique is described to improve the pictures in view of sharp boundary models. Some models are finally presented, mostly regarding cubic buried anomalies as well as pipe-shaped and L-shaped anomalies.
SNPs detection by eBWT positional clustering
2019
Sequencing technologies keep on turning cheaper and faster, thus putting a growing pressure for data structures designed to efficiently store raw data, and possibly perform analysis therein. In this view, there is a growing interest in alignment-free and reference-free variants calling methods that only make use of (suitably indexed) raw reads data. We develop the positional clustering theory that (i) describes how the extended Burrows–Wheeler Transform (eBWT) of a collection of reads tends to cluster together bases that cover the same genome position (ii) predicts the size of such clusters, and (iii) exhibits an elegant and precise LCP array based procedure to locate such clusters in the e…
Biodiversity of Antarctic echinoids: a comprehensive and interactive database
2005
Eighty-one echinoid species are present south of the Antarctic Convergence, and they represent an important component of the benthic fauna. “Antarctic echinoids” is an interactive database synthesising the results of more than 100 years of Antarctic expeditions, and comprising information about all echinoid species. It includes illustrated keys for determination of the species, and information about their morphology and ecology (text, illustrations and glossary) and their distribution (maps and histograms of bathymetrical distribution); the sources of the information (bibliography, collections and expeditions) are also provided. All these data (taxonomic, morphologic, geographic, bathymetri…
Task Planner for Robotic Disassembly of Electric Vehicle Battery Pack
2021
The rapidly growing deployment of Electric Vehicles (EV) put strong demands on the development of Lithium-Ion Batteries (LIBs) but also into its dismantling process, a necessary step for circular economy. The aim of this study is therefore to develop an autonomous task planner for the dismantling of EV Lithium-Ion Battery pack to a module level through the design and implementation of a computer vision system. This research contributes to moving closer towards fully automated EV battery robotic dismantling, an inevitable step for a sustainable world transition to an electric economy. For the proposed task planner the main functions consist in identifying LIB components and their locations, …
Softening of Silica Filled Styrene-Butadiene Rubber under Uniaxial Cyclic Loading
2016
Stress-strain behaviour of silica filled styrene-butadiene rubber showed strong hysteresis and cyclic softening, while these effects were almost negligible for the neat rubber. Significant Mullins effect occurs between the first and second loading cycles, whereupon samples reach their steady state after four repeated cycles. The degree of softening increases with volume content of silica characterizing the softening effect as a breakdown of the filler-formed microstructure defined by both, specific interactions in the filler associations and between the filler and rubber matrix. Contribution of different damage mechanisms to the total energy losses on different stages of extension was estim…
