Finite element modeling of delamination in advanced composite beams and plates using one- and two-dimensional finite elements based on the refined zigzag theory
Although laminated materials have been used for decades, their employment has increased nowadays in the last years as a result of the gained confidence of the industry on these materials. This has provided the scientific ...
Finite Element Models of Volcano Deformational Systems Having Structural Complexity
The main focus of this work is to build 3-D FEM models with structural complexities in order to simulate volcanic systems in a more realistic way. We use Rabaul as an example to show the application of the methods and ...
Finite element simulation of additive manufacturing with enhanced accuracy
This thesis develops numerical methods to improve the accuracy and computational efficiency of the part-scale simulation of Additive Manufacturing (AM) (or 3D printing) metal processes. AM is characterized by multiple ...
Finite element simulation of the healthy and degenerated lumbar spine : interplay between muscle activity and intervertebral disc multiphysics
The human spine provides mechanical support to the trunk while it protects the spinal cord and nerves from the external loads transferred during daily activities. Such loads are largely controlled by the spine muscles and ...
Finite groups acting on smooth and symplectic 4-manifolds
En esta tesis se estudian problemas relacionados con acciones de grupos finitos en 4-variedades diferenciables y simplécticas. Se prueba que toda 4-variedad diferenciable cerrada X admite una constante C>0 tal que cualquier ...
Finite Models of Splicing and Their Complexity
Durante las dos últimas décadas ha surgido una colaboración estrecha entre informáticos, bioquímicos y biólogos moleculares, que ha dado lugar a la investigación en un área conocida como la computación biomolecular. El ...
Fire blight (Erwinia amylovora) of rosaceous plants. Pathogen virulence and selection and characterization of biological control agents
El fuego bacteriano, causado por Erwinia amylovora, es una enfermedad muy importante a nivel comercial y económico porque afecta a plantas de la familia de las rosáceas y es especialmente agresiva en manzano (Pyrus malus) ...
Fire Detectors Based on Chemical Sensor Arrays and Machine Learning Algorithms: Calibration and Test
In some types of fire, namely, smoldering fires or involving polymers without flame, gases and volatiles appear before smoke is released. Most of the fatalities registered for fires, are caused due to the intoxication of ...
Fire legacies in Mediterranean streams: the key roles of the riparian canopy and the top predator on food webs
Wildfires are expected to increase in frequency and intensity because of climate change and changes in land use and management. In last decades, the research on fire effects on aquatic systems has grown, but it has been ...
Fire recurrence effects on Pinus halepensis Mill. communities of Catalonia
Se estudiaron los efectos de la recurrencia del fuego en comunidades vegetales Mediterráneas dominadas por el árbol germinador P.halepensis Mill. (pino carrasco) a nivel regional en Cataluña. Entre 8 y 11 años tras la ...
Fire risk analysis framework at the wildland-urban interface
(English) Wildfires that reach the border between the wildland and urban areas, defined as the Wildland-Urban Interface (WUI), have rapidly expanded in frequency and severity over the past few decades, and the number of ...
Firm growth, persistence and multiplicity of equilibria: an analysis of Spanish manufacturing and service industries.
This thesis examines to what extent the firm size influences on firm growth and their behaviour of Spanish manufactures and service industries between 1994 and 2002 from the stochastic growth theory. The study has not only ...
Firm Sustained Growth
Aquesta tesi respon a la pregunta de “Com les empreses creixen de forma sostenible en contexts dinàmics”, una de les qüestions fonamentals de la literatura d’estratègia. La tesi està formada per tres estudis que aborden ...
Firm value and performance analysis: Impact and implications of implementing sustainability initiatives for the airline industry
Aquesta tesi doctoral es basa en l'estudi de l'associació del valor de la signatura empresarial, el rendiment financer (FP, sigles en anglès) i les iniciatives de sostenibilitat aplicades a la indústria de transport aeri. ...
Firm, stakeholders, value dynamics and social economic progress. The case of the Spanish pharmaceutical industry
La manera en que l’empresa crea valor és la primera etapa d’un cicle de dues fases. La segona és la distribució (apropiació) del valor creat a mans dels stakeholders. Com a conseqüència, les dinàmiques de valor són un eix ...
Firma de la aplicación paralela para predecir el rendimiento
Evaluar el rendimiento de una aplicación paralela es cada vez más complejo. Una vez terminado el desarrollo, cuando una aplicación pasa a producción, el rendimiento y la eficiencia son fundamentales para los usuarios y ...
Firm’s management of systematic risk: one source and two strategies
Esta tesis desarrolla varios aspectos de la gestión del riesgo sistemático en la empresa, identificando inicialmente una fuente que lo genera (manipulación del resultado), seguida de dos estrategias que, bajo ciertas ...
The First lady: from the kitchen to the podium : how to gender equality revolution and the media forged a new political actor in democratic systems
The first ladyship is nowadays one of the most mediatized, yet scientifically neglected unofficial institutions to be found in contemporary states. It raises various questions regarding the nature of modern relations between ...
First measurement of beta-decay half-lives and neutron emission probabilities in several isotopes beyond N = 126
In this work beta-decay half-lives and neutron-emission probability values have been experimentally determined for first time in several nuclei beyond the neutron-shell closure at N=126. To this aim the accelerator complex ...
First measurements of radiative B decays in LHCb
Radiative decays of B mesons, a good example of Flavor Changing Neutral Currents, are interesting for the study of physics beyond the Standard Model, as new high-energy phenomena can enter in the loop. The LHCb experiment, ...
