Quantum Monte Carlo study of few-and many-body bose systems in one and two dimensions
In this Thesis, we report a detailed study of the ground-state properties of a set of quantum few- and many-body systems by using Quantum Monte Carlo methods. First, we introduced the Variational Monte Carlo and Diffusion ...
Intracavity spatial filtering in broad area semiconductor laser
Semiconductor lasers in high-power regime typically manifest a poor beam quality due to its asymmetric beam divergence and its large beam quality factor (M2). The emission along one of the transverse directions (slow axis) ...
Large-scale CFD and micro-particles simulations in a large human airways under sniff condition and drug delivery application
As we inhale, the air drawn through our nose undergoes successive accelerations and decelerations as it is turned, split, and recombined before splitting again at the end of the trachea as it enters the bronchi. Fully ...
Exploring free-energy landscapes and microscopic interactions of selected small-molecules and proteins with cell membranes
The present Thesis is devoted to the study of the physical-chemical properties of selected small-molecules (such as amino-acids like tryptophan or hormones like melatonin) and proteins (such as KRAS-4B) absorbed in model ...
Hybrid non-destructive technique for volumetric defect analysis and reconstruction by remote laser induced ultrasound
This PhD thesis is devoted to the design, development and implementation of a non-contact hybrid non-destructive testing (NDT) method applied to the analysis of metallic objects that contain embedded defects or fractures. ...
Multiapproach computational modelling of tuberculosis : understanding its epidemiological dynamics for improving its control in Nigeria
Tuberculosis (TB) is an infectious disease that is considered to be the biggest killer of mankind in the history of infectious diseases. There are still more than 10 million new TB cases every year and it causes more than ...
Modelling pathological effects in intracellular calcium dynamics leading to atrial fibrillation
The heart beating is produced by the synchronization of the cardiac cells' contraction. A dysregulation in this mechanism may produce episodes of abnormal heart contraction. The origin of these abnormalities often lies at ...
Estimation of binding free energies with Monte Carlo atomistic simulations and enhanced sampling
The advances in computing power have motivated the hope that computational methods can accelerate the pace of drug discovery pipelines. For this, fast, reliable and user-friendly tools are required. One of the fields that ...
Neuronal encoding and transmission of weak periodic signals
Sensory neurons use sequences of electrical pulses (known as action potentials or spikes) to encode and transmit information of external temporal stimuli. Neural coding is the research field that studies the relationship ...
Machine learning methods for the characterization and classification of complex data
This thesis work presents novel methods for the analysis and classification of medical images and, more generally, complex data. First, an unsupervised machine learning method is proposed to order anterior chamber OCT ...
Nuevas aproximaciones al estudio de la dinámica de la relajación dieléctrica en ferroeléctricos ordinarios y relajadores
Ferroelectric materials are endowed with fascinating functional properties from the technological point of view. Consequently, they have promoted the design of ferroelectric-based devices with applications in a vast range ...
Experimental study of speckle generated by semiconductor light sources: application in double pass imaging
With the double pass (DP) technique it is possible to quantify the optical quality of a patient's eye by measuring its point spread function. Due to the low reflectivity of the retina a high-intensity, point-like illumination ...
Ultracold Bose and Fermi dipolar gases : a quantum Monte Carlo study
The object of study of this thesis are dipolar systems in the quantum degenerate regime. In general, dealing with many-body systems and evaluating their properties requires to deal with the the Schrödinger equation. In the ...
Decolourization of textile wastewater by manganese-aluminium metallic particles
Waste treatment is an important aspect of an industry. Organic dyes are used in many fields, such as textile, paper or food. Residual dye compounds from these industries are one of the most critical sources of environmental ...
Estudio de la inhomogeneidad elástica en vidrios metalicos en la mesoescala
Metallic glasses are amorphous solids produced by rapid cooling, with disordered atomic structure and lacking long-range order. This structural disorder makes them to show mechanical properties different from those observed ...
Hilbert analysis of air temperature dynamics
The dynamics of the climate system plays a crucial role in the sustainability of life on Earth, and this motivates research to understand and characterise our climate and predict its evolution. In this thesis we focus on ...
Data-driven neural mass modelling
The brain is a complex organ whose activity spans multiple scales, both spatial and temporal. The computational unit of the brain is thought to be the neurone. At the microscopic level, neurones communicate via action ...
Study of the meteorological mechanisms controlling levels and transport processes of airborne pollen in the atmosphere
Aerobiology is the science that focuses on the study of the airborne living organisms (bacteria, fungal spores, pollen, small insects, etc.). The influence of meteorology and climate change on plant phenology include shifts ...
Dynamics and physical processes involving extreme temperatures in the Iberian Peninsula and Iraq
The occurrence of heat waves and cold spells has received special attention in recent years due to their impact on human health, ecosystems and economy. In the context of climate change, there is evidence that extreme ...
Relaxation dynamics and crystallization kinetics of glass-forming drugs
Glassy phases play an important role in our daily life and in many industries such as the food, pharmaceutical, and construction and are responsible for certain vital mechanisms in living species. Whereas crystals are solid ...
