Funciones test para optimización mono-objetivo
2018
Para resolver la mayor parte de problemas de optimización del mundo real son necesarias técnicas sofisticadas, tales como los algoritmos evolutivos, que no se basan en el Cálculo Infinitesimal y que, en consecuencia, nunca caben en los planes de estudios de los grados en ciencia e ingeniería. No obstante, el ingeniero tendrá que utilizar tales técnicas antes o después. Para poner a prueba la habilidad de tales técnicas de optimización se suelen utilizar problemas de benchmarking que exhiben algunas de las características de los problemas del mundo real. En este artículo enumeramos brevemente algunas de tales características y presentamos una colección de problemas de optimización mono-objet…
Mírame, contrólame, protégeme. ¿Soy un coche? La publicidad sexista en televisión y su regulación en España: Análisis crítico discursivo del sexismo …
2017
A diario podemos ver anuncios televisivos en los que se utiliza la representación de hombres y mujeres para publicitar sus productos o servicios. De forma un tanto velada, encontramos mensajes impregnados de tintes discriminatorios que siguen distando mucho de las indicaciones establecidas por los organismos e instituciones en cuanto a la igualdad de género, al tiempo que incumplen la normativa vigente. De esta forma, tenemos en el ámbito publicitario la presencia de un sexismo más sutil pero igualmente pernicioso, en el que ambos géneros, aunque especialmente las mujeres, reciben un tratamiento desigual. Dicho sexismo indirecto se abre camino mediante recursos que operan a nivel pragmático…
Recursos informáticos para el aprendizaje de las matemáticas mediante metáforas musicales: el proceso de creación y evaluación de PicaLab.
2018
El proyecto PicaLab propone el diseño, elaboración y evaluación de recursos informáticos modulares para la enseñanza y el aprendizaje de contenidos matemáticos a través del sonido y la música, en los niveles de tercero, cuarto y quinto año de Educación Básica en Chile. Si bien estos fueron diseñados como recursos para la sala de clases, pueden ser usados por las y los estudiantes fuera de ese contexto. El proceso ha seguido la metodología de investigación de las ciencias del diseño con el fin de diseñar prototipos funcionales de naturaleza multimodal en conjunto con sus guías didácticas: 1) identificación del problema, que permite detectar necesidades y construir un marco teórico ad hoc; 2)…
Developing picture communication for interactional situations at the beginning of the asylum process; mapping interactional practices
2019
The paper reports the initial findings of the first phase of the research and development project PICCORE – Picture Communication in Reception Centres. The goal was to map the use of pictures and other visual modes of communication at reception centres in Finland using an ethnographic, multimodal research approach. The ethnographic data was collected at four reception c entres in Finland. A multimodal viewpoint draws attention to how action and meanings are mediated through pictures. The initial findings mark established practices for enabling and coordinating mutual attention, supporting the use of visual and embodied resources in interactions and – as a consequence – supporting mutual und…
Decoupled Acoustic and Visual Components in the Multimodal Signals of the Common Cuckoo (Cuculus canorus)
2021
Because of its parasitic habits, reproduction costs of the common cuckoo (Cuculus canorus) are mostly spent in pre-laying activities. Female costs are limited to searching host nests and laying eggs, whereas, males spend time in performing intense vocal displays, possibly with territorial purpose. This last aspect, together with a sexual plumage dimorphism, points to both intra- and inter-sexual selections operating within this species. One element triggering sexual selection is a differential fitness accrued by different phenotypes. Before analyzing possible sexual selection mechanisms operating in cuckoos, it is therefore necessary to verify whether there is a variability among male secon…
Employing fuzzy logic in the diagnosis of a clinical case
2010
Fuzzy logic is a logical calculus which operates with many truth values (while classical logic works with the two values of true and false). Since fuzzy logic considers the truth of scientific statements like something softened, it is fruitfully applied to the study of biological phenomena, biology is indeed considered the field of complexity, uncertainty and vagueness. In this paper fuzzy logic is successfully applied to the clinical diagnosis of a patient who suffers from different diseases bound by a complex causal chain. In this work it is presented a mathematical foundation of fuzzy logic (with connectives and inference rules) and then the application of fuzzy reasoning to the study of…
Synthesis and bio-functionalization of magnetic nanoparticles for medical diagnosis and treatment
2011
The synthesis of multifunctional magnetic nanoparticles (NPs) is a highly active area of current research located at the interface between materials science, biotechnology and medicine. By virtue of their unique physical properties magnetic nanoparticles are emerging as a new class of diagnostic probes for multimodal tracking and as contrast agents for MRI. Furthermore, they show great potential as carriers for targeted drug and gene delivery, since reactive agents, such as drug molecules or large biomolecules (including genes and antibodies), can easily be attached to their surface. On the other hand, the fate of the nanoparticles inside the body is mainly determined by the interactions wi…

Fiberless, Multi-Channel fNIRS-EEG System Based on Silicon Photomultipliers: Towards Sensitive and Ecological Mapping of Brain Activity and Neurovasc…
2020
Portable neuroimaging technologies can be employed for long-term monitoring of neurophysiological and neuropathological states. Functional Near-Infrared Spectroscopy (fNIRS) and Electroencephalography (EEG) are highly suited for such a purpose. Their multimodal integration allows the evaluation of hemodynamic and electrical brain activity together with neurovascular coupling. An innovative fNIRS-EEG system is here presented. The system integrated a novel continuous-wave fNIRS component and a modified commercial EEG device. fNIRS probing relied on fiberless technology based on light emitting diodes and silicon photomultipliers (SiPMs). SiPMs are sensitive semiconductor detectors, whose large…
SART and Individual Trial Mistake Thresholds: Predictive Model for Mobility Decline
2021
The Sustained Attention to Response Task (SART) has been used to measure neurocognitive functions in older adults. However, simplified average features of this complex dataset may result in loss of primary information and fail to express associations between test performance and clinically meaningful outcomes. Here, we describe a new method to visualise individual trial (raw) information obtained from the SART test, vis-à-vis age, and groups based on mobility status in a large population-based study of ageing in Ireland. A thresholding method, based on the individual trial number of mistakes, was employed to better visualise poorer SART performances, and was statistically validated with bin…
