Intervertebral disc (IVD) degeneration is primarily involved in back pain, a morbidity that strongly affects the quality of life of individuals nowadays. Lumbar IVDs undergo stressful mechanical loads while being the largest ...
The development of urban models based on mathematical and physics concepts has been one of the most intense scientific areas of research for the last two decades in urban studies. Cellular automata (CA), a mathematical ...
The present dissertation aims at addressing multiscale topology optimization problems. For this purpose, the concept of topology derivative in conjunction with the computational homogenization method is considered. In ...
In recent years, there have been considerable efforts in the design and development of technologies and techniques for more efficient harvesting of renewable energy resources to meet the ever increasing electric power ...
Depth map data is used to supplement the color data in multi-view sequences. As depth maps present distinct Characteristics than natural color images, new coding techniques are required to represent their smooth regions ...
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 ...
Respiratory sounds (RS) are produced by turbulent airflows through the airways and are inhomogeneously transmitted through different media to the chest surface, where they can be recorded in a non-invasive way. Due to ...
From single-core CPUs to detachable compute accelerators, supercomputers made a tremendous progress by using available transistors on chip and specializing hardware for a given type of computation. Today, compute nodes ...
In the the last decades several performance walls were hit. The memory wall and the power wall are limiting the performance scaling of digital microprocessors. Homogeneous multicores rely on thread-level parallelism, which ...
This thesis attempts to bring together two recent topics by presenting a flexible Transactional Memory environment on a multicore prototype that is realized on FPGA fabric. For this, we devise a MIPS-compatible shared-memory ...
This thesis deals with the processing of different types of multidimensional SAR data for distinct applications. Instead of handling the original pixels of the image, which correspond to very local information and are ...
Los Radares de Apertura Sintética, o sistemas SAR, representan el mejorejemplo de sistemas activos de teledetección por microondas. Debido a su naturaleza coherente, un sistema SAR es capaz de adquirir información dedispersión ...
Last decade, providers started using Virtual Machines (VMs) in their datacenters to pack users and their applications. This was a good way to consolidate multiple users in fewer physical nodes while isolating them from ...
Cementitious materials such as mortar or concrete are brittle and have an inherent weakness in resisting tensile stresses. The addition of discontinuous fibers to such matrices leads to a dramatic improvement in their ...
This thesis focuses on the development of active multifunctional dressing materials and nanoparticle formulations with suitable exploitation characteristics for chronic wounds treatment. Chronic wounds a growing clinical ...
Chronic wounds became burdensome problem of worldwide healthcare systems, along with the increased elderly population, which is the most vulnerable risk group, predisposed to their development. Chronic wounds represent a ...
Over the last decades, Metamaterials (MTMs) have caught the attention of the scientific community. Metamaterials are basically artificially engineered materials which can provide unusual electromagnetic properties not ...
El Método de los Momentos (MoM) ha sido ampliamente utilizado en las últimas décadas para la discretización y la solución de las formulaciones de ecuación integral que aparecen en muchos problemas electromagnéticos de ...
La motivación principal de esta tesis es el desarrollo de nuevas técnicas de compilación dirigidas a conseguir mayor rendimiento encódigos numéricos complejos que definen es pacios de iteraciones no rectangulares. En ...
Within the visual system, the optics of the eye is responsible for forming images of external objects on the ocular fundus for its photo-reception and neural interpretation. However, the eye is not perfect and its capabilities ...
