La segmentación de imágenes es una técnica que tiene como finalidad dividir una imagen en un conjunto de regiones, asignando a cada objeto en la escena una o varias regiones. Para obtener una segmentación correcta, cada ...
Venturini, Chiara (Date of defense: 2022-07-22)
Integrin-based cell adhesion is a key mechanism in fundamental biological processes such as cell migration and wound healing, and in diseases like osteoporosis and cancer. For example, during migration, cells form adhesion ...
Vallmitjana Lees, Alexander (Date of defense: 2017-09-22)
Cardiac myocytes constitute a unique physiological system. They are the muscle cells that build up heart tissue and provide the force to pump blood by synchronously contracting at every beat. This contraction is regulated ...

Physical vapor deposited hard coatings comprised of cubic (c) transition metal (TM)-Al-N, and (TM)-Si-N are the current work horse materials for a large number of metal cutting and wear resistant applicatíons to light ...
El Azhari, Idriss (Date of defense: 2020-07-21)
The present dissertation is an in-depth investigation from the macro to atomic scale of industrial wear-resistant CVD hard coatings deposited on cemented carbides for cutting tool applications. Micro-compression tests at ...
Zaghi, Stefano (Date of defense: 2019-01-21)
The improvements in terms of computational power provides the capability to analyze with more detail the materials behavior. On one hand, going deeper in the materials to study an increasingly smaller dimension and capture ...
Otero Gruer, Fermin (Date of defense: 2016-02-09)
Most of the existing materials around us can be considered composite materials, since they are composed by several phases or components at certain spatial scale. The physical and chemical properties of composites, as occurs ...
Piles Guillem, Maria (Date of defense: 2010-07-16)
La humedad del suelo es la variable que regula los intercambios de agua, energía, y carbono entre la tierra y la atmósfera. Mediciones precisas de humedad son necesarias para una gestión sostenible de los recursos hídricos, ...
Sciandra, Dario (Date of defense: 2024-02-09)
(English) Geological Carbon Storage (GCS) holds immense promise for mitigating atmospheric CO2 emissions, making the sealing capacity of caprocks pivotal as storage scales up. Despite excellent sealing capacities observed ...
