29 p, 594.7 KB New lower bound for the Hilbert number in piecewise quadratic differential systems / Da Cruz, Leonardo Pereira Costa (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Novaes, Douglas D. (Universidade Estadual de Campinas (Brasil). Departamento de Matemática) ; Torregrosa, Joan (Universitat Autònoma de Barcelona.

In microorganisms, Ion Torrent sequencing technology has been proved to be useful in whole-genome sequencing of bacterial genomes (5 Mbp). In our study, for the first time we used this technology to perform a resequencing approach in a whole fungal genome (36 Mbp), a non-ochratoxin A producing strain of Aspergillus carbonarius. [...]

9 p, 94.0 KB La cosmología de Hermann de Carintia : el De essentiis (1143) / Tauste Alcocer, Francisco (Societat Catalana de Filosofia)
El De essentiis es el mejor exponente de las ideas cosmológicas que están en vigor en los ambientes culturales cercanos a los traductores de Toledo y al entorno de Pedro el Venerable. Fue escrito por Hermann de Carintia, uno de los traductores que estuvo en contacto con los pensadores de Chartres y de los reinos cristianos peninsulares del siglo xii. [...]
The De essentiis is the best exponent of the cosmological ideas that prevail in the cultural environments of the translators of Toledo and the intellectual milieu of Peter the venerable. It was written by Hermann of Carinthia, one of the translators who was in contact with the thinkers of Chartres and the peninsular Christian kingdoms of the twelfth century. [...]

4 p, 283.1 KB Pràctica sobre el càlcul de les propietats fonamentals del so a partir de la freqüència d'ultrasò d'ecolocalització dels ratpenats / Arcas Rivas, Pedro (IES Institut Ribot i Serra (Sabadell)) ; Fenollar Moncho, José (IES Institut Ribot i Serra (Sabadell))
El ratpenat o quiròpter emet unes freqüències d'ultrasò en forma de crit (generalment entre 20 i 120 kHz). En aquesta pràctica treballarem conceptes relacionats amb les característiques d'aquest so, detectat amb el detector Bat Tune: freqüència f, període T, freqüència angular o pulsació w, longitud d'ona λ i el nombre d'ona k.
The different species of bats emits some ultrasound frequencies in a form of ultrasound (usually between 20 and 120 kHz). In this practice we will work on concepts related to the characteristics of this sound, detected with the Bat Tune detector: frequency f, period T, angular frequency or pulsation w, length of wave λ and the number of wave k.

Department of Telecommunications and Media Informatics) ; Szűcs, Gábor (Budapest University of Technology and Economics. Department of Telecommunications and Media Informatics)
In this paper we present an automatic clustering procedure with the main aim to predict the number of clusters of unknown, heterogeneous images. We used the Fisher-vector for mathematical representation of the images and these vectors were considered as input data points for the clustering algorithm. [...]
