A joint model for 2D and 3D pose estimation from a single image
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Conference report
Restricted access - publisher's policyWe introduce a novel approach to automatically recover 3D human pose from a single image. Most previous work follows a pipelined approach: initially, a set of 2D features such as edges, joints or silhouettes are detected ... -
An experimental and numerical investigation on fatigue of composite and metal aircraft structures
(2022-04)
Article
Open AccessThe static strength and fatigue crack resistance of the aircraft skin structures depend on the materials used and joint type. Most of the commercial aircraft’s skin panel structures are made from aluminium alloy and carbon ... -
Analysis of back-propagation and RF pilot-tone based nonlinearity compensation for a 9x224Gb/s POLMUX-16QAM system
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Conference report
Restricted access - publisher's policyWe investigate the joint implementation of back-propagation and RF-pilot tone for fiber nonlinear compensation in POLMUX-16QAM and show that the nonlinear tolerance is drastically improved when compared to OFDM system -

Master thesis (pre-Bologna period)
Open AccessEl present projecte tractarà d'estudiar i analitzar articulacions del cos humà i establir una relació entre la pràctica de l'esport i l'estat de la salut de les persones. -
Experimental study of concrete slab–base interaction for a seamless bridge–CRCP system
(American Society of Civil Engineers (ASCE), 2023-06)
Article
Open AccessConventional bridge systems make use of expansion joints to accommodate movements caused primarily by thermal changes. These joints may accelerate the deterioration of bridge elements and often require significant maintenance ... -
Experimental testing of joints for seismic design of lightweight structures: part 1: screwed joints in straps
(2006-02)
Article
Open AccessConnections in x-braced shear walls play a crucial role in the seismic performance of lightweight structures: they should be strong enough to allow energy dissipation via plastification of the diagonal straps. An extensive ... -
Experimental testing of joints for seismic design of lightweight structures: part 2: bolted joints in straps
(2006-06)
Article
Open AccessAn experimental testing campaign on tensile bolted joints between straps is reported. Two dominant failure modes are identified: (1) tilting, bearing and tearing of the sheets (TS) and (2) tilting, bearing and net-section ... -
Inflammation evaluation through low-cost 3D scanning of human body parts
(Universitat Politècnica de Catalunya, 2015-01-28)
Bachelor thesis
Open Access[CATALÀ] S'ha creat un programa que permet carregar models 3D adquirits a partir d'articulacions reals. Utilitzant diferents tècniques com l'alineació de models, la comparació visual i el càlcul de diferents mesures l'eina ... -
Joints in concrete construtions: study and analysis of characteristics of joints in exposed concrete: the case of contemporary buildings in Barcelona
(Universitat Politècnica de Catalunya, 2022-07-07)
Bachelor thesis
Open AccessJoints play a crucial role in both the design and the materialization of concrete construction and in its subsequent service and durability. Especially when it comes to exposed concrete, their appearances might affect the ... -

Open AccessEl análisis de la marcha ha adquirido en los últimos tiempos un extraordinario desarrollo. En la actualidad la ciencia biomecánica ofrece un gran campo de actuación para el estudio de la patología de la deambulación, ... -
Numerical modeling of the double punch test for plain concrete
(2011-04)
Article
Open AccessDouble punch test is used to indirectly assess the tensile strength of plain concrete, ft. For this normalized test, the tensile strength is obtained as a function of the failure load, P, which is expressed as f_t = F(P). ... -
Simulation and validation of a dynamic model for a biobot representing a human joint
