Floer homology for 𝑏-symplectic manifolds
(English) In this thesis we investigate various aspects of the dynamics of Hamiltonian vector fields in singular symplectic manifolds. We concentrate on two questions: first, we investigate a generalization of the Arnold ...
Bridging the gap between object stores and HPC
(English) Efficient data management is a fundamental aspect of application workflows, particularly in the context of High-Performance Computing environments. This thesis examines the potential of object stores as a robust ...
Aporte a la construcción de comunidades sostenibles. Un modelo para analizar su sostenibilidad
(English) This thesis developed an understanding of what makes a community sustainable, its particular characteristics, the values it shares, its way of life and its interaction with natural systems. It categorized the ...
Leveraging the potential of task-based programming with OpenMP task graphs
(English) The task execution model is widely used in computer engineering, it helps developers to design, develop and understand software systems. OpenMP is the de-facto programming model to parallelize sequential algorithms ...
New synthesis methodologies to develop emerging chalcogenides and chalcohalides for photovoltaic applications
(English) Chalcogenide materials have been central to some of the most significant events in the history of photovoltaic energy, including the fabrication of the first solar cell in 1883 by Charles Fritts, which was based ...
Automatismes, usuaris i arquitectura: aplicació a la gestió energètica dels edificis
(English) Digitalization and automation are being applied across various sectors of society, including buildings through Building Automation and Control Systems (BACS). These systems enable, for instance, the management ...
Optimization techniques in science planning for planetary exploration missions
(English) Solar System robotic missions explore objects in space to elicit key information that contributes to our understanding of the origins and evolution of the Solar System as well as of life. Noticeably, such an ...
THM numerical modeling of multiphase flow in fractured rock masses using zero-thickness interface elements
(English) To address the impacts of climate change, several measures have been suggested among which utilizing renewable energy sources such as geothermal energy and implementing technologies such as hydrogen storage or ...
Optimization techniques for distributed task-based programming models
(English) In HPC, task-based models have gained prominence via the adoption of tasks in OpenMP, as an asynchronous and platform-agnostic high-performance and productive model by annotating existing code, transforming it ...
Development of a multimodal imaging system based on LIDAR
(English) Perception of the environment is an essential requirement for the fields of autonomous vehicles and robotics, that claim for high amounts of data to make reliable decisions. With this aim, many different sensors ...
A comprehensive proposal for the sustainable regeneration of historical city centres in Iran
(English) This thesis focuses on the "sustainable regeneration of the historic centres of Iran's cities" under a comprehensive and participatory approach and consists of a collection of four self-contained articles and an ...
Recovery of phenolic compounds from olive mill and winery wastes: evaluation of extraction and membrane processing technologies
(English) Olive oil and wine production are two major agri-food economic activities in Spain; and generate large amounts of solid and liquid wastes that represent an important environmental problem. In this context, the ...
Aspectos ambientales en la Casa Aversú de Alejandro de la Sota: el proceso del proyecto
(English) This research stems from two personal interests: climate awareness and Alejandro de la Sota. Based on this premise, the aim of the research is to find the connection between environmental aspects and architecture, ...
3D-printed biomimetic bone
(English) Over 2 million bone grafting procedures are performed each year. In the last years, synthetic calcium phosphates have drawn the attention of the researchers for their close similarity to the mineral phase of bone ...
Social sciences and humanities in civil engineering: a mixed methods analysis in the context of education
(English) The challenges that the world is currently facing call for solutions that are interdisciplinary in nature. This implies that engineering professionals need to work together with professionals from different ...
Multifunctional eco-friendly aerogel composites for thermal insulation and fire resistant applications
(English) Replacing petroleum-based polymers with natural alternatives requires overcoming the limitations of their thermal and mechanical properties, as well as the inherently low fire resistance of the biomass from which ...
Fault diagnosis and fault-tolerant control of nonlinear dynamic systems using artificial intelligence techniques
(English) This thesis attempts to reduce the gap between the approaches developed by researchers to build a fault tolerant system and their implementation in a real system. The most widespread methodologies are model-based ...
Elementos junta/interfase mortar con nudos no coincidentes. Aplicación al análisis de discontinuidades y contactos en geomecánica
(English) The general objectives of this thesis are, on the one hand, to extend the formulation of the traditional zero-thickness interface elements in small deformations to the case of non-coincident meshes and, on the ...
Development of high performance cement-based composites reinforced with nonwoven fabrics from sustainable raw materials and textile wastes
(English) Currently there is a growing concern about the sustainability of the construction sector due to its great contribution to climate change. Approximately one third of carbon dioxide emissions are produced by this ...
Modeling and control in open-channel irrigation systems
(English) This thesis is devoted to exploring existing research around modeling, control, and estimation strategies in OCIS, in order to identify improvement opportunities and propose new strategies that increase their ...
