A contribution to the theory of convolutional codes from systems theory piont of view
Information is such a valuable good of our time. Given that the transmission of information has always been subject to precision problems, knowing the obstacles existing between the transmitter and the receiver, eventual ...
A contribution to the use, modelling and organization of data in biodiversity conservation
Aquesta tesi fa una contribució al tractament de les limitacions en les dades de biodiversitat, presències d'espècies, per a produir mapes útils en la conservació de la biodiversitat mitjançant l'ús dels models de distribució ...
A controller-driven approach for Opportunistic Networking
Les xarxes oportunistes (OppNets) aprofiten les oportunitats de contacte entre els nodes, el quals utilitzen l’habilitat de comunicar-se directament entre ells, per fer fluir les dades a través d’una xarxa mancada ...
A Convex Decomposition Perspective on Dynamic Bandwidth Allocation and Applications
Tradicionalment, les tècniques d'accés múltiple en sistemes de comunicacions multi-usuari han estat desenvolupades o bé orientades a la connexió o bé orientades al tràfic. En el primer cas, l'objectiu és establir tants ...
A corpus-based study of the phraseological behaviour of abstract nouns in medical English. A Needs Analysis of a Spanish medical community
It has been long acknowledged (Carter 1998, Williams 1998; Biber 2006; Hyland 2008) that writing a text not only entails the accurate selection of correct terms and grammatical constructions but also a good command of ...
A cotangent bundle Hamiltonian tube theorem and its applications in reduction theory
The Marle-Guillemin-Sternberg (MGS) model is an extremely important tool for the theory of Hamiltonian actions on symplectic manifolds. It has been extensively used to prove many local results both in symplectic geometry ...
A coupled CFD-DEM model for sand production in oil wells
During the oil recovery a hole is drilled, the sandstone is left unsupported next to the cavity and disloged sand grains can enter the oil recovery system. This process is called sand production and several problems may ...
A coupled Eulerian-PFEM model for the simulation of overtopping in rockfill dams
Rockfill dams are nowadays often preferred over concrete dams because of their economic advantages, their flexible design and thank to the great advance achieved in geosciences and geomechanics. Unfortunately their behavior ...
A coupling matrix vision for mobile filtering devices with micro-acoustic wave technologies. A systematic approach
Con el espectro radioeléctrico cada vez más saturado, los filtros y duplexores son elementos claves de la tecnología en el mercado de dispositivos discretos para la telefonía móvil. El segmento de usuario de los sistemas ...
A critical approach to the discursive construction of work and the self as an employee in present-day greece
Estudios en varias disciplinas de las ciencias sociales han señalado que se está desarrollando una despolitización estratégica del trabajo remunerado, junto con la constitución del sujeto como emprendedor autosuficiente y ...
A critical sociolinguistic study of diasporization among Hungarians in Catalonia
This thesis investigates how contemporary diasporas evolve, how diasporization takes place under the conditions of late modernity, and how language features in this process. By diasporization, I refer to the process(es) ...

A cross-layer mechanism for QoS improvements in VoIP over multi-rate WLAN networks
In IEEE 802.11 WLANs, Link Adaptation mechanisms, which choose the transmission rate of each node, provoke unexpected and random variations on the effective channel capacity. When these changes are towards lower bitrates, ...
A Cross-linguistic comparison of the verbs of speaking with the component of non-standard speech and their translation (English-Russian)
In this dissertation we examine the sphere of the English verbs of speaking (VoS) with 2 components: the manner of speaking component (MoSC) and the component of non-standard speech (CoNS), and their translations from ...
A damage-based fatigue life prediction method for metallic alloys and composites
(English) Fatigue failures in materials have been studied for centuries, with early pioneers like August Wöhler noting that repeated loading, even below the static strength of the material, could lead to structural ...
A data-driven approach to prescribe web API evolution
(English) In the last two decades, the use of web Application Programming Interfaces (APIs) has grown exponentially, providing both consumers (software developers) and providers (companies and institutions that expose their ...
A decision support framework for holistic forest management: bridging policy and practice
La gestió forestal en temps de canvi global requereix un enfoc holístic basat en els principis de la Gestió Forestal Sostenible (GFS). No obstant, aquests principis rarament es consideren en criteris operatius per al ...
