A critical period of susceptibility to sound in the sensory cells of cephalopod hatchlings
(2018-01-01)
Article
Accés obertThe cephalopod statocyst and lateral line systems are sensory organs involved in orientation and balance. Lateral lines allow cephalopods to detect particle motion and are used for locating prey or predators in low light ... -
CNNs for electron microscopy segmentation
(Universitat Politècnica de Catalunya / École Polytechnique Fédérale de Lausanne, 2013)
Treball Final de Grau
Accés restringit per decisió de l'autor
Realitzat a/amb: École Polytechnique Fédérale de LausanneIn the framework of Biomedicine, mitochondria are known to play an important role in neural function. Recent studies show mitochondrial morphology to be crucial to cellular physiology and synaptic function, and a link ... -
Does exposure to noise from human activities compromise sensory information from cephalopod statocysts?
(2013-10-15)
Article
Accés restringit per política de l'editorialMany anthropogenic noise sources are nowadays contributing to the general noise budget of the oceans. The extent to which sound in the sea impacts and affects marine life is a topic of considerable current interest both ... -
Electromagnetic shielding effectiveness of polycarbonate/graphene nanocomposite foams processed in 2-steps with supercritical carbon dioxide
(2015)
Article
Accés obertThe electromagnetic interference (EMI) shielding properties of polycarbonate/graphene composites foamed with supercritical carbon dioxide were investigated as a function of cellular morphology and graphene particle dispersion. ... -

Influence of carbon content on microstructure and properties of a steel matrix cermet
(2018-09-01)
Article
Accés restringit per política de l'editorialThere is a marked correlation between the composition, microstructure and properties in TiCN-based cermets. In the case of using iron alloys as metallic matrix the carbon content is of particular significance, as not only ... -
Kinetics and crystallization path of a Fe-based metallic glass alloy
(2017-04-01)
Article
Accés obertThe thermal stability and the quantification of the different transformation processes involved in the overall crystallization of the Fe50Cr15Mo14C15B6 amorphous alloy were investigated by several characterization techniques. ... -
Production and characterization of Fe-based metallic glasses
(Universitat Politècnica de Catalunya, 2008-06-20)
Projecte Final de Màster Oficial
Accés obertAmorphous metallic alloys were developed at 1960. Since then, scientists have not stopped researching in order to improve their properties and find new applications. The innovation in techniques has let to the creation ... -
Sistema de tractament d'imatges per a la mida de Nanopartícules
(Universitat Politècnica de Catalunya, 2018-01-18)

Article
Accés restringit per política de l'editorialThe structural characterization of chiral nylon-3 derivative, poly (3-ethyl-3-phenyl-2- azetidinone) (PEPA) has been carried out using FTIR, thermal analysis, X-ray diffraction and electron microscopy. X-ray diffraction ... -
Surface defect of IF steel after the deep drawing process
(Universitat Politècnica de Catalunya / Universiteit Gent, 2014)
Treball Final de Grau
Accés restringit per decisió de l'autor
Realitzat a/amb: Universiteit GentThe aim of this project is to run large EBSD analysis in samples of IF steel in order to look for unusual crystallographic patterns that can provide an explanation for the defects that are observed after the deep drawing ... -
TED: a tolerant edit distance for segmentation evaluation
(2017-02-15)
Article
Accés obertIn this paper, we present a novel error measure to compare a computer-generated segmentation of images or volumes against ground truth. This measure, which we call Tolerant Edit Distance (TED), is motivated by two observations ... -
Templated growth of tungsten oxide micro/nanostructures using aerosol assisted chemical vapour deposition
(2008-12)
Article
Accés restringit per política de l'editorialPorous anodized alumina (PAA) and macroporous silicon (MS) substrates have been used to template the growth of tungsten oxide via aerosol assisted chemical vapour deposition from the precursor tungsten hexaphenoxide. The ... -
Ultrasensitive interferometric on-chip microscopy of transparent objects
(2016-06)
Article
Accés obertLight microscopes can detect objects through several physical processes, such as scattering, absorption, and reflection. In transparent objects, these mechanisms are often too weak, and interference effects are more suitable ...
