The knowledge transfer in traditional enterprises has been deeply studied, although there are no articles to be treated within the university spin-off companies, which often operate in dynamic environments. In this paper ...
Human-machine interaction in teleoperation, through the adequate user interface, allows achieving the level of intelligence necessary to execute complex tasks that cannot be executed by machines or robots alone neither ...
La tesis presenta un modelo no recursivo de sistemas no lineales (SNLS) basado en las series de fourier, estableciendo una comparación con el modelo de volterra en términos de coste computacional y diseño. <br/><br/>Del ...
In the present thesis a theoretical and empirical study of the relationship between transformational leadership (TL) styles and organizational commitment (OC) is performed. These two concepts are examined as multidimensional ...
This Thesis studies different cellular and cell population processes driven by non-linear and stochastic dynamics. The problems addressed here gravitate around the concepts of transient dynamics and relaxation from a ...
The atmospheric boundary layer is the part of the troposphere influenced by the presence of the surface, and where most weather phenomena occur. During the day, with fair weather conditions, a convective boundary layer ...
Several clinical studies for non-invasive estimation of tissue hemodynamics by the combination of two diffuse optical techniques, time-resolved and diffuse correlation spectroscopy, were carried out in collaboration with ...
Worldwide, the coherent technologies have revolutionized the optical communication systems, significantly increasing the capacity of the fiber channel owing to transmission of advanced modulation formats and effective ...
The emergence of very capable mobile terminals, e.g. smartphones or tablets, has dramatically increased the demand of wireless data traffic in recent years. Current growth forecasts elucidate that wireless communication ...
Over the last few decades, transistor miniaturization has enabled a tremendous increase in the processing capability of commercial electronic devices, which, combined with the reduction of production costs, has tremendously ...
Current theories and mechanisms of nerve impulse propagation inside neurons do not give a satisfactory explanation to the nanoscale processes that occur inside the membrane. Propagation at the dendritic zones, and at the ...
Cache-coherent shared memory has traditionally been the favorite memory organization for chip multiprocessors thanks to its high programmability. In this organization the cache hierarchy is in charge of moving the data and ...
Aquesta tesi tracta la protecció de dades quan aquestes han de ser lliurades a usuaris en qui no es té absoluta confiança. En aquesta situació, les dades s'han de protegir de manera que segueixin essent utilitzables. Aquesta ...
(English) The properties of ultrathin materials present exciting opportunities to develop multifunctional surfaces. In addition, the use of plastic and thin glass as transparent substrates has the potential to extend the ...
The rapid evolution of the cruise industry in the last 50 years is evident. In the nineteenth century, cruise ships were simple modes of transport used by immigrants to travel on transoceanic voyages from Europe to North ...
Cementitious materials are used as barriers in radioactive waste storage. Hence, transport processes in this kind of material are important. The objective of this thesis is to improve the understanding of transport of water ...
The thesis asks about the forms of the region and finds answer in the landscape. The work focuses on the study of a fragment of the interior of Galicia. The labyrinthine topography proper to the area, with significant slope ...
Textile industry consumes large amount of water in their processes, mainly in dyeing and finishing operations. In general, during the dyeing process, up to 30% of dyes used can be discharged into wastewater. For this reason, ...
El éxito clínico de los implantes dentales, fabricados en titanio comercialmente puro (Ti c.p.), está basado en la consecución de la osteointegración, es decir, la conexión directa estructural y funcional entre el hueso ...
Los tejidos de algodón se someten a procesos de preparación (desencolado, descrudado y blanqueo) basados en la eliminación de impurezas presentes en la superficie de la fibra. Actualmente se blanquean con peróxido de ...
