En esta tesis se abordan tres temas de investigación diferentes: i) electrospray débilmente viscoelástico, ii) la aparición del efecto whipping en la técnica de Flow Focusing, y iii) la interacción fluido-estructura (FSI) implementando un modelo de canal colapsable 2D. i) Se ha realizado una comparación sistemática y teórica entre un fluido...

We consider the stability of flux-driven flow through a long planar rigid channel, where a segment of one wall is replaced by a pre-tensioned hyperelastic (neo-Hookean) solid of finite thickness and subject to a uniform external pressure. We construct the steady configuration of the nonlinear system using Newton's method with spectral...

Given a 3D binary digital image I, we define and compute an edge-weighted tree, called Homological Region Tree (or Hom-Tree, for short). It coincides, as unweighted graph, with the classical Region Adjacency Tree of black 6-connected components (CCs) and white 26- connected components of I. In addition, we define the weight of an edge (R, S) as...

Fractal dimension is a powerful tool employed as a measurement of geometric aspects. In this work we propose a method of topological fractal analysis for 2D binary digital images by using a graph-based topological model of them, called Homological Spanning Forest (HSF, for short). Defined at interpixel level, this set of two trees allows to...

Segmentations of a digital object based on a connectivity criterion at n-xel or sub-n-xel level are useful tools in image topological analysis and recognition. Working with cell complex analogous of digital objects, an example of this kind of segmentation is that obtained from the combinatorial representation so called Homological Spanning...

Topological representations of binary digital images usually take into consideration different adjacency types between colors.Within the cubical-voxel 3D binary image context, we design an algorithm for computing the isotopic model of an image, called (6, 26)-Homological Region Adjacency Tree ((6, 26)-Hom-Tree). This algorithm is based on a...

Among the different polymers (proteins, polysaccharides, etc.) that make up natural fibers, fibroin is a protein produced by silk spinning animals, which have developed an optimized system for the conversion of a highly concentrated solution of this protein into high-performance solid fibers. This protein undergoes a self-assembly process in...

La hipoacusia constituye una condición incapacitante que dificulta la comunicación y la calidad de vida. Hallazgos recientes han expuesto los efectos que ejerce en el deterioro cognitivo, lo cual destaca su dimensión multifac-torial y la necesidad de crear conjuntos de datos audiológicos multimodales que cubran de forma más extensa datos...
