Uno de los problemas más complejos en redes de computadores es el de proporcionar garantías de calidad y confiabilidad a las comunicaciones de datos entre entidades que se encuentran en dominios distintos. Esto se debe a ...
The requirement for imaging living structures with higher contrast and resolution has been covered by the inherent advantages offered by nonlinear microscopy (NLM). However, to achieve its full potential there are still ...
(English) This doctoral thesis focuses on the design of strategies (i.e., exact and heuristic-based methods) to optimize the placement and reconfiguration of user plane functions (UPFs) in 5G and beyond networks. These ...
Microalgae-based wastewater treatment systems are promising solutions to shift the paradigm from wastewater treatment to energy and resources recovery. In these systems, microalgae assimilate nutrients and produce oxygen ...
El desarrollo del strategizing, concepto introducido por Whittington (1996) que enfoca la estrategia en la práctica “cómo algo que las personas hacen”, surgió por la creciente insatisfacción con la investigación convencional ...
Este estudio se centra en el uso del texto estratégico desde el punto de vista de los directivos académicos. La línea de investigación en estrategia se ha interesado por las prácticas, actividades y comportamientos de los ...
We develop the theory of perturbations of matrix pencils basing on their miniversal deformations. Several applications of this theory are given. All possible Kronecker pencils that are canonical forms of pencils in an ...
This thesis presents some approaches for guided wave based stress monitoring as a part of Structural Health Monitoring (SHM). SHM systems include different levels, from damage detection to prognosis, however, this work is ...
In this thesis, we develop a general theory to describe the dynamics of electrons that are ionized when an atom or molecule is exposed to a strong low frequency laser field. Our approach extends and improves the well-established ...
Simple games are a fundamental class of cooperative games. They have a huge relevance in several areas of computer science, social sciences and discrete applied mathematics. The algorithmic and computational complexity ...
Graphene, a two-dimensional sp2-hybridized network of carbon atoms has received a remarkable cornucopia of new physics and served as a unique model system, due particularly to its electronic properties, which could have ...
Dietary polyphenols represent a group of secondary metabolites which widely occur in fruits, vegetables, wine, tea, extra virgin olive oil, chocolate and other cocoa products. Previous studies have shown the interaction ...
BACKGROUND: Retinal evaluation performed in the optometry clinic allows optometrists to track the prognosis of retinal disease and to assess anatomical and functional changes related to age and pathological and non-pathological ...
AT-rich sequences confer unique properties to DNA, such as high polymorphism and flexibility. The abundance of AT-rich DNA in several pathogens' genomes and the ability of specific molecules to selectively target AT base ...
(English) Cotton, being a natural hollow fiber with remarkable economic values including moisture absorption, air permeability, softness, comfort, and warmth retention, has become one of the most essential raw materials ...
Spatial Arch Bridges (SABs) are defined as bridges in which vertical deck loads produce bending moments and shear forces not contained in the arch plane due to their geometrical and structural configuration. Moreover, the ...
(English) This thesis investigates the response of carbon and stainless steel frames in fire, and proposes new and more efficient approaches for their design. The investigation is mainly focused on one bay frames comprised ...
Since ancient times, master builders have used arches to cover large spans in masonry structures. As a consequence, nowadays the safety assessment of these structural elements plays a fundamental role in the conservation ...
(English) Stainless steel is one of the most promising construction materials due to its long service life, low maintenance requirements, excellent mechanical properties and high residual value. Nevertheless, for an efficient ...
Tapered plate girders often form part of large-scale structures such as long continuous bridges or industrial buildings where due to considerable loads the higher resistance is required. There are several important reasons ...
