Análisis del engagement y el burnout y su relación con las prácticas organizacionales saludables (POS)
(English) Managing the development of workers in the organization, their well-being, health and performance, should not be questioned in a world that shows day by day that it is people who, with their humanity, creativity ...
Methodology for malleable applications on distributed memory systems
(English) The dominant programming approach for scientific and industrial computing on clusters is MPI+X. While there are a variety of approaches within the node, denoted by the ``X'', Message Passing interface (MPI) is ...
Leveraging disaggregated accelerators and non-volatile memories to improve the efficiency of modern datacenters
(English) Traditional data centers consist of computing nodes that possess all the resources physically attached. When there was the need to deal with more significant demands, the solution has been to either add more nodes ...
Uniones y elementos de conexión para estructuras con bambú: clasificación y desarrollo de un prototipo de conexión
(English) Bamboo is a material of great importance in different civilizations of Asia and Latin America. Its use goes from the roots to the leaves, which are raw material to make edible products, furniture and construction ...
Equilibrado de líneas de montaje en paralelo con estaciones multilínea y dimensionado de buffers
(English) Assembly lines are mass production systems which are relevant in the manufacture of standard and customized products. One of the most elementary optimization problems in this field is the Assembly Line Balancing ...
Development of a VHF broadband interferometer to investigate unsolved lightning phenomena: high-energy radiation from lightning strikes and multi-stroke positive cloud-to-ground flashes
(English) The aim of this thesis work is the development of a VHF broadband interferometer for lightning research. The observations with this instrument allowed us to investigate some unsolved aspects of lightning related ...
Esfahan multi-node metropolis: conflicts and opportunities on urban nodes and intersections

Possibilities and limitations of active battery management systems for lithium-ion batteries
(English) Lithium-Ion Batteries (LIBs) are being used in more and more areas of application. At the same time, their chemical composition and their designs are constantly evolving. Major developments are also taking place ...
Investigating quantum many-body systems with tensor networks, machine learning and quantum computers
(English) We perform quantum simulation on classical and quantum computers and set up a machine learning framework in which we can map out phase diagrams of known and unknown quantum many-body systems in an unsupervised ...
Contributions to nanophotonics: linear, nonlinear and quantum phenomena
(English) Nanophotonics can be defined as the science and technology studying the control optical fields at the nanoscale and their interaction with matter. In order to spatially control such fields we would need structures ...
From the production of the single cell to the end of life of the battery module: the development of parameter variation of lithium-ion cells
(English) In lithium-ion batteries, depending on the requirements, many individual cells are connected in series and parallel. Despite very similar individual cell parameters after production, they can develop differently ...
Coupling shallow water models with three-dimensional models for the study of fluid-structure interaction problems using the particle finite element method
(English) This thesis investigates numerical methods for the simulation of surface water flows, focusing on the interaction between the large scale and the local scale and its application to natural hazards. Several families ...
Development of low-cost sensors for structural health monitoring applications
