Stability and Limit Oscillations of a Control Event-Based Sampling Criterion

This paper investigates the presence of limit oscillations in an adaptive sampling system. The basic sampling criterion operates in the sense that each next sampling occurs when the absolute difference of the signal amplitude with respect to its currently sampled signal equalizes a prescribed threshold amplitude. The sampling criterion is extended involving a prescribed set of amplitudes. The limit oscillations might be interpreted through the equivalence of the adaptive sampling and hold device with a nonlinear one consisting of a relay with multiple hysteresis whose parameterization is, in general, dependent on the initial conditions of the dynamic system. The performed study is performed on the time domain.

Sampling and learning the Mallows and Generalized Mallows models under the Cayley distance

[EN]The Mallows and Generalized Mallows models are compact yet powerful and natural ways of representing a probability distribution over the space of permutations. In this paper we deal with the problems of sampling and learning (estimating) such distributions when the metric on permutations is the Cayley distance. We propose new methods for both operations, whose performance is shown through several experiments. We also introduce novel procedures to count and randomly generate permutations at a given Cayley distance both with and without certain structural restrictions. An application in the field of biology is given to motivate the interest of this model.

Sampling and learning the Mallows and Weighted Mallows models under the Hamming distance

[EN]In this paper we deal with distributions over permutation spaces. The Mallows model is the mode l in use. The associated distance for permutations is the Hamming distance.

Sampling and learning the Mallows model under the Ulam distance

[EN]In this paper we deal with probability distributions over permutation spaces. The Probability model in use is the Mallows model. The distance for permutations that the model uses in the Ulam distance.

Bertso transformation with pattern-based sampling

This paper presents a method to generate new melodies, based on conserving the semiotic structure of a template piece. A pattern discovery algorithm is applied to a template piece to extract significant segments: those that are repeated and those that are transposed in the piece. Two strategies are combined to describe the semiotic coherence structure of the template piece: inter-segment coherence and intra-segment coherence. Once the structure is described it is used as a template for new musical content that is generated using a statistical model created from a corpus of bertso melodies and iteratively improved using a stochastic optimization method. Results show that the method presented here effectively describes a coherence structure of a piece by discovering repetition and transposition relations between segments, and also by representing the relations among notes within the segments. For bertso generation the method correctly conserves all intra and inter-segment coherence of the template, and the optimization method produces coherent generated melodies.

Diseño de un programa de Surf recreativo enfocado a colectivos con Síndrome de Down de 6 a 10 años

El objetivo de este trabajo es diseñar un programa de surf recreativo enfocado a colectivos con Síndrome de Down de 6 a 10 años. El Síndrome de Down se define como una discapacidad intelectual causada por una alteración en el par de cromosomas 21 (OMS, 2011). Resulta de especial relevancia el tratamiento de dicha discapacidad de manera no farmacológica, destacando la actividad física, en este caso el surf, como elemento inclusivo a nivel físico, psicológico y social. Se analizan distintos programas de Actividad Física en el medio acuático con personas con Síndrome de Down y se presenta el Surf como elemento que provoca grandes beneficios. A continuación se presenta el diseño de un programa que podría llevarse a cabo en un entorno cercano a nuestro territorio con un atractivo elevado ya que se trata de un proyecto innovador y beneficioso para personas con Síndrome de Down y sus familiares.

Down sindromea duen kolektiboaren agilidadean, koordinazioan eta orekan taekwondo-a duen eragina

[EUS] Proiektu honen bitartez, Down sindromea pairatzen duten, >14 urteko 8 parte hartzaileen agilidadea, koordinazioa eta oreka ebaluatu izan da, taekwondo-ko ordu bateko lau saio eginez. Aipaturiko faktoreak neurtzeko, ECOMI eskala egokitua erabili da. Hau, lehenengo eta azkenengo saioetan erabili izan da, datuak hartzeko eta konparaketak egin ahal izateko, eboluzioa ikusiz. Neurketak behin eginda, ikusi egin da bai koordinazioan eta orekan hobekuntzak izan dituztela orokorrean, aldiz, agilitatean ez da hobekuntza aipagarririk egon, eta aldi berean, parte hartzaileen arteko aldea nahiko nabarmena izan da. Hobekuntza ezak edo txikiak izateak, denbora eskasagatik izan dela esan daiteke. Beste autore batzuen esanetan, 20 saiotan hobekuntza nabarmenak lortu daitezke.

Down sindromea duten umeen inklusibitatea eta dantza klasikoaren onurak haiengan

Gai honekiko interesa, aurreko urtean “Jarduera fisiko inklusiboa” irakasgaia hasi genuenean piztu zitzaidan eta lan hau egitea erabakitzearen arrazoia, dantza campus batean monitore moduan bizitako esperientzia izan zen. Bertan, gaixotasun ezberdinak zituzten umeak elkartu ziren gure klubeko umeekin batera lan egiteko eta dantza egiten gozatzen zutena ikusita gozatzen nuen nik ere. Baina bereziki, Down Sindromea (DS) duten umeekin lan egiteko gogoa sortu zitzaidan. Horren geroztik, gaixotasun hau duten pertsonekin lan egiten duten dantza taldeak badaudela aurkitu nuen, baina nire asmoa ez da soilik DS duten umeei dantza egiten irakastea, baizik eta ume hauen eta gaixotasunik ez dutenen arteko elkarlana bultzatzea ere, inklusibitatea hain zuzen, baita dantzak haiengan sortzen dituen onurak aztertzea ere, bai fisiko zein psikologikoki.
