Online drawings for dementia diagnose: in-air and pressure information analysis
(2014)In this paper we present experimental results comparing on-line drawings for control population (left and right hand) as well as Alzheimer disease patients. The drawings have been acquired by means ... -
Spontaneous Speech and Emotional Response modeling based on One-class classifier oriented to Alzheimer Disease diagnosis
(2014)The purpose of our project is to contribute to earlier diagnosis of AD and better estimates of its severity by using automatic analysis performed through new biomarkers extracted from non-invasive ... -
Improving Pitch Tracking Performance in Hard Noise Conditions by a Preprocessing Based on Mathematical Morphology
(2009)In this paper we show how a nonlinear preprocessing of speech signal -with high noise- based on morphological filters improves the performance of robust algorithms for pitch tracking (RAPT). This ... -
Exploring Non-linear Transformations for an Entropybased Voice Activity Detector
(2009)In this paper we explore the use of non-linear transformations in order to improve the performance of an entropy based voice activity detector (VAD). The idea of using a non-linear transformation comes ... -
On cumulant techniques in speech processing
(2009)This paper analyzes applications of cumulant analysis in speech processing. A special focus is made on different second-order statistics. A dominant role is played by an integral representation ... -
Campus Móvil: Designing a Mobile Web 2.0 Startup for Higher Education Uses
(2010)In the intersection between the mobile Internet, social software and educational environments, Campus Móvil is a prototype of an online application for mobile devices created for a Spanish university ... -
An experimental features selection approach in a multiclass classifier
(2013)This paper focuses on an experimental feature selection for the images of otoliths in order to validate their effectiveness in a multiclass classifier used to resolve an automatic otolith identification ... -
Closed Contour Shape Descriptors with High Compression Properties Based on the Discrete Hartley Transform
(2013)The quantitative analysis of shapes is required in some research fields, such as taxonomy, agronomy, ecology, medicine, among others. The quantification of an object shape, or a biological entity shape ... -
Automatic Trend Line Generation f or timeseries analysis: a Graphical Approach
(2013)Trend lines are revealed useful to explain the past evolution of timeseries of prices that are represented on graphics. However, in practice, there are a huge amount of possible trend lines to be ... -
Improving Early Diagnosis of Alzheimer's Disease Using Synchrony Measures
(2013)It is well-known that Alzheimer's disease causes changes on the electroencephalography of the patients. However those changes are difficult to parameterize. In this paper a new ratio between synchrony ... -
Otoliths identifiers using image contours EFD
(2010)Abstract. In this paper we analyze the characteristics of an experimental otolith identification system based on image contours described with Elliptical Fourier Descriptors (EFD). Otoliths are found ... -
Monotonic AC-Compatible Semantic Path Orderings
(2003)Abstract. Polynomial interpretations and RPO-like orderings allow one to prove termination of Associative and Commutative (AC-)rewriting by only checkingthe rules of the given rewrite system. However, ... -
Complete Monotonic Semantic Path Orderings
(2000)Although theoretically it is very powerful, the semantic path ordering (SPO) is not so udeful in practice, since its monotonicity has to be proved by hand for each concrete term rewrite system (TRS). ... -
El Diseño: 7 visiones transversales
(2012)El diseño ha evolucionado de manera sorprendente en las últimos años gracias a la tecnología, potenciando diferentes disciplinas y especializaciones en las que influyen aspectos técnicos y de percepción ... -
m-Todos, tendencias y oportunidades de la movilidad digital
(2011-12)La difusión de la tercera generación de dispositivos móviles y su integración con la World Wide Web son un reto para los medios de comunicación. Como en cualquier otro ecosistema, la llegada de una ... -
La premsa comarcal i el consum de noves pantalles
(2012-05)La investigació es centra en la visió dels mitjans de proximitat i el consum de d’aquests mitjans en el marc de la convergència digital a Catalunya. No és cap misteri l’aparició de nous hàbits de consum ... -
Mobile Communication 2012 : Experiències i recerques sobre comunicació mòbil
