The project Paleo3D is a project for innovative teaching methodologies in the field of Palaeontology. Its main goals are the development of mobile devices apps and the creation of a web page that can help in the education of courses in this field. The common thread of the developed materials will be the collections of […]

In project PARAMVALVE the main goal is to build a parametric model of the aorta geometry based on a reduced number of characteristics that can be used in these kind of models. This model will be used to develop a computational pipeline that helps the simulation of blood flow and the obtention of clinically meaningful information.

We focus on the problem of shock wave formation in a model of blood flow along an elastic artery. We analyze the conditions under which this phenomenon can appear and we provide an estimation of the instant of shock formation. Numerical simulations of the model have been conducted using the Discontinuous Galerkin Finite Element Method. […]

The reconstruction of the ventricular cardiac conduction system (CCS) from patient‐specific data is a challenging problem. High‐resolution imaging techniques have allowed only the segmentation of proximal sections of the CCS from images acquired ex vivo. In this paper, we present an algorithm to estimate the location of a set of Purkinje‐myocardial junctions (PMJs) from electro‐anatomical […]

Introduction: Focal atrial tachycardia is commonly treated by radio frequency ablation with an acceptable long-term success. Although the location of ectopic foci tends to appear in specific hot-spots, they can be located virtually in any atrial region. Multi-electrode surface ECG systems allow acquiring dense body surface potential maps (BSPM) for non-invasive therapy planning of cardiac […]

We propose a constraint-basedmodel of viscoelasticity that enables efficient simulation of highly viscousand viscoelastic phenomena.

Modeling the cardiac conduction system is a challenging problem in the context of computational cardiac electrophysiology. Its ventricular section, the Purkinje system, is responsible for triggering tissue electrical activation at discrete terminal locations, which subsequently spreads throughout the ventricles. In this paper, we present an algorithm that is capable of estimating the location of the […]

Rosa Sánchez, estudiante del Grado en Ingeniería Multimedia, de la ETSE-UV, presento el pasado miércoles el artículo Real-time Inextensible Hair with Volume and Shape en el Congreso Español de Informática Gráfica. En el artículo se propone una nueva estrategia computacional para combinar diferentes efectos en la simulación de cabello para videojuegos. Los autores del artículo son Rosa […]

Texture advection techniques, which transport textures using a velocity field, are used to visualize the dynamics of a flow on a triangle mesh. Some flow phenomena lead to velocity fields with discontinuities that cause the deformation of the texture which is not properly controlled by these techniques. We propose a method to detect and visualize […]

Contact Clustering for Deformable Soil Interaction has been accepted as a poster in SCA'12. Our main goal is to determine several contact regions from an unstructured set of contact data, in order to apply deformation-pressure models from terramechanics. This work has been developed with Miguel Lozano, Marta Pla-Castells and Juanma Orduña. Project page. In this […]
