In this thesis, we present two computational platforms for future biological research. The first, FNAC, is a flexible programmatic Framework for Network Analysis and Comparison that simplifies many common operations on biological networks. As a demonstration of FNAC, we investigate the properties of several prominent protein function and protein-protein interaction networks. In doing so, we uncover evidence suggesting that a recently-developed technique for annotating proteins may also have substantial value in the computational prediction of protein-protein interactions. Our second computational platform, the Coiled-Coil Database (CCDB), serves as a central and easily queryable repository for information about the coiled coil protein structural motif in a variety of organisms.

Texto completoLos avances tecnológicos en la secuenciación de próxima generación (NGS) han revolucionado el campo de la genómica. El aumento de velocidad y rendimiento de las tecnologías NGS de los últimos años junto con la reducción de su coste ha permitido interrogar base por base el genoma humano de una manera eficiente y asequible. Todos estos avances han permitido incrementar el uso de las tecnologías NGS en la práctica clínica para la identificación de variaciones genómicas y su relación con determinadas enfermedades. Sin embargo, sigue siendo necesario mejorar la accesibilidad, el procesamiento y la interpretación de los datos debido a la enorme cantidad de datos generados y a la gran cantidad de herramientas disponibles para procesarlos. Además de la gran cantidad de algoritmos disponibles para el descubrimiento de variantes, cada tipo de variación y de datos requiere un algoritmo específico. Por ello, se requiere una sólida formación en bioinformática tanto para poder seleccionar el algoritmo más adecuado como para ser capaz de ejecutarlo correctamente. Partiendo de esa base, el objetivo de este proyecto es facilitar el procesamiento de datos de secuenciación para la identificación e interpretación de variantes para los no bioinformáticos. Todo ello mediante la creación de flujos de trabajo de alto rendimiento y con una sólida base científica, sin dejar de ser accesibles y fáciles de utilizar, así como de una plataforma sencilla y muy intuitiva para la interpretación de datos. Se ha realizado una exhaustiva revisión bibliográfica donde se han seleccionado los mejores algoritmos con los que crear flujos de trabajo automáticos para el descubrimiento de variantes cortas germinales (SNPs e indels) y variantes estructurales germinales (SV), incluyendo tanto CNV como reordenamientos cromosómicos, de ADN humano moderno. Además de crear flujos de trabajo para el descubrimiento de variantes, se ha implementado un flujo para la optimización in silico de la detección de CNV a partir de datos de WES y TS (isoCNV). Se ha demostrado que dicha optimización aumenta la sensibilidad de detección utilizando solo datos NGS, lo que es especialmente importante para el diagnóstico clínico. Además, se ha desarrollado un flujo de trabajo para el descubrimiento de variantes mediante la integración de datos de WES y RNA-seq (varRED) que ha demostrado aumentar el número de variantes detectadas sobre las identificadas cuando solo se utilizan datos de WES. Es importante señalar que la identificación de variantes no solo es importante para las poblaciones modernas, el estudio de las variaciones en genomas antiguos es esencial para comprender la evolución humana. Por ello, se ha implementado un flujo de trabajo para la identificación de variantes cortas a partir de muestras antiguas de WGS. Dicho flujo se ha aplicado a una mandíbula humana datada entre el 16980-16510 a.C. Las variantes ancestrales allí descubiertas se informaron sin mayor interpretación debido a la baja cobertura de la muestra. Finalmente, se ha implementado GINO para facilitar la interpretación de las variantes identificadas por los flujos de trabajo desarrollados en esta tesis. GINO es una plataforma fácil de usar para la visualización e interpretación de variantes germinales que requiere licencia de uso. Con el desarrollo de esta tesis se ha conseguido implementar las herramientas necesarias para la identificación de alto rendimiento de todos los tipos de variantes germinales, así como de una poderosa plataforma para visualizar dichas variantes de forma sencilla y rápida. El uso de esta plataforma permite a los no bioinformáticos centrarse en interpretar los resultados sin tener que preocuparse por el procesamiento de los datos con la garantía de que estos sean científicamente robustos. Además, ha sentado las bases para en un futuro próximo implementar una plataforma para el completo análisis y visualización de datos genómicos

Texto completoThe demand for network throughput is increasing due to the continued growth of global traffic and the emergence of new services with ever higher requirements. In this context, the capacity of the network should be increased while taking into account the energy consumption, its cost of construction and maintenance. The combination of optical networks with packet-oriented processing could meet these requirements. However, because of the lack of all practical optical memory, packet switching is most often performed electrically causing the architecture to be costly expensive and less efficient.Thereby, as part of the ANR / N-GREEN project, a new switch/router architecture that provides solutions to these constraints has been proposed by a research team at Nokia Bell Labs. The architecture was designed to meet the stringent requirements of 5G such as end-to-end delay of 10μs but also to meet the traffic increase planned especially in the Metropolitan Area Network (MAN). Such architecture can therefore be used not only in the access/core part of the MAN but also in the core as well as in the Xhaul consider the 5G technology . In this dissertation, we have been interested in analyzing and improving the performance of this new node design when it is used in the MAN part.Indeed, taking this into consideration, an Optical Slot Switching (OSS) ring network, combining the flexibility and scaling of slot switching technique with the advantages of ring topology such as fast service restoration in case of failure and a good gain in static multiplexing of traffic, would promise a good solution for MAN networks of the future. This new architecture offers intelligent functions, with a lower cost by optimizing the type / number of components used. Such an architecture can replace existing optoelectronic technology such as Ethernet or other promising solution proposed in the literature such as POADM (Optical Package Add Drop Muliplexing) or TWIIN (Time-Domain Wavelength Interleaved Networking (TWIN). The fundamental element of the network is the WSADM (Wavelength Slotted Add Drop Muliptexer) which is implemented inside the nodes of the networks, guaranteeing hence the optical transparency and a faster switching.In this thesis, we analyzed the performance in terms of mean access delay and resource efficiency of a ring network composed of a number of NGREEN nodes. We have used some optimization methods such as Nelader Mead Simplex calculating dynamically the optimal values of the timers (average waiting time of a packet before being inserted in the optical ring), adapting thus the architecture to different types of traffic. Three different models of traffics were considered in this study: besides the most well-known Poisson model, two models based on traces of real traffic deduced from CAIDA traces were considered.Inspired by the idea of the loop controllers, we tried later to find a way to self-adapt the network facing constant changes in traffic. As we talk about a constant adaptation of the strategy in noisy conditions, we proposed a very variable traffic model, more variable than the one drawn from CAIDA trace. Observing the effect of the changing frequency of one of the coefficients that govern the strategy of packets ‘transmission on the momentary performance of the network; allowed to find a frequency range, where an instantaneous dependency between the stimulus and the response direct a self-adaptation scheme of the proposed strategyThe performance analysis of this architecture, taking into account different traffic models, shows that, thanks to the methods proposed and the application of optimization, the network responds to users' needs in terms of packet loss rates, latency

Texto completoIn the first part of the thesis a wavelet-based adaptive image deconvolution algorithm (AWMLE) has been applied to two sets of survey type CCD data: QUasar Equatorial Survey Team project(QUEST and Near-Earth Space Surveillance Terrestrial(NESS-T). Richardson-Lucy image deconvolution has also been used with Flagstaff Transit Telescope (FASTT)imagery. Both the obtaining and performance of those images were accomplished by following a new methodology which includes accurate image calibration, source detection and centering, and correct assessment procedures of the performance of the deconvolution. Results show that AWMLE deconvolution can increase limiting magnitude up to 0.6 mag and improve limiting resolution 1 pixel with respect to original image. These studies have been conducted in the context of programs dedicated to macrolensing search (QUEST) and NEOs discovery(NESS-T). Finally, astrometric accuracy of FASTT images have not been found to change significantly after deconvolution. In the same way, no positional bias towards the centre of the pixel has been observed.
In the second part of the thesis a new observational technique based on CCD fast drift scanning has been proposed, implemented and assessed for lunar occultations (LO) and speckle interferometry observations.
In the case of LO, the technique yielded positive detection of binaries up to 2 milliarcseconds of projected separation and stellar diameters measurements in the 7 milliarcsecond regime. The proposed technique implies no optical or mechanical additional adjustments and can be applied to nearly all available full frame CCDs. Thus, it enables all kind of professional and high-end amateur observatories for LO work. Complementary to this work, a four-year LO program (CALOP) at Calar Alto Observatory spanning 71.5 nights of observation and 388 recorded events has been conducted by means of CCD and MAGIC IR array cameras at OAN 1.5m and CAHA 2.2m telescopes. CALOP results include the detection of one triple system and 14 new and 1 known binaries in the near-IR, and one binary in the visible. Their projected separations range from 90 to 2 milliarcseconds with brightness ratios up to 1:35 in the K band. Several angular diameters have been also measured in the near-IR. The performance of CALOP has been calibrated in terms of limiting magnitude (K down to 9.0) and limiting angular resolution (1-3 milliarcseconds).
In addition, the binary detection probability of the program has found to be about 4%. Finally, a new wavelet-based method for extracting and characterizing LO lightcurves in an automated fashion was proposed, implemented and applied to CALOP database. This pipeline addresses the need of disposing of preliminary results in immediate basis for future programs which will provide larger number of events.
In the case of speckle interferometry, CCD fast drift scanning technique has been validated with the observation of four binary systems with well determined orbits. The results of separation, position angle and magnitude difference are in accordance with published measurements by other observers and predicted orbits. Error estimates for these have been found to be 0.017 arcseconds, 1.5 degrees and 0.34 mag, respectively. These are in the order of other authors and can be considered as successful for a first trial of this technique.
Finally, a new approach for calibrating speckle transfer function from the binary power spectrum itself has been introduced. It does not require point source observations, which gives a more effective use of observation time. This new calibration method appears to be limited to zenith angles above 30 degrees when observing with no refraction compensation devices.
En aquest treball s'han dissenyat i desenvolupat una sèrie de noves tècniques observacionals i eines d'anàlisi de dades en dues àrees ben diferenciades. D'una banda, la deconvolució d'imatges CCD de gran camp (tipus survey). D'altra banda, l'astrometria d'alta resolució, i en particular les tècniques observacionals d'ocultacions lunars i interferometria speckle.
Quant a la primera, s'han aplicat dos algorismes de deconvolució (màxima versemblança Richardson-Lucy (MLE) i la seva variant adaptativa basada en wavelets (AWMLE)) a dades de tres projectes survey: el Flagstaff Transit Telescope (FASTT), el QUasar Equatorial Survey Team (QUEST) i el Near-Earth Space Surveillance Terrestrial (NESS-T). Els tres han vist restringida la seva magnitud i resolució límits a causa del mètode d'adquisició drift scanning (per a FASTT i QUEST) o la molt curta relació focal de l'instrument (NESS-T). S'ha proposat i implementat una nova metodologia per a l'aplicació de l'AWMLE i MLE per a les anteriors imatges. Aquesta permet avaluar la millora aportada per la deconvolució en termes d'increment de magnitud i resolució límits. A més, resulta del tot general i és exportable a altres dades survey. Els resultats obtinguts mostren que AWMLE permet aconseguir un increment en la magnitud límit de 0.6 mag i una millora en la resolució límit d'1.0 pixel. A més, s'ha comprovat que tals tendències són assimtòticament independents a partir d'un nombre d'iteracions suficientment gran. Paral·lelament, s'ha comprovat que la deconvolució MLE sobre dades FASTT no afecta significativament a la precisió astromètrica ni introdueix cap biaix posicional cap al centre del píxel.
Quant a les ocultacions lunars, s'ha ideat, desenvolupat, implementat i avaluat una nova tècnica d'observació CCD per a ocultacions lunars. Éstà basada en el mètode d'adquisició "drift scanning" i permet mostrejar la intensitat de l'objecte ocultat cada 2ms. La tècnica permet a pràcticament qualsevol observatori (professional o amateur) afrontar programes d'ocultacions lunars amb propòsits de contribució científica. Paral·lelament, s'ha portat a terme un programa d'observació d'ocultacions lunars (anomenat CALOP) que durant 4 anys i 71.5 nits s'ha portat a terme a l'Observatorio Astronómico de Calar Alto, operant tant en el visible amb CCD com en l'IR amb la càmera MAGIC. Com a resultat, s'han aconseguit mesurar 3 diàmetres estel·lars de l'ordre de 7 mil.lisegons d'arc i detectar 15 nous sistemes binaris i un triple amb separacions angulars de fins a 2 mil.lisegons d'arc. Finalment, s'ha desenvolupat i implementat un nou algorisme de reducció automàtica d'ocultacions basat en wavelets. Tal algorisme ha estat aplicat satisfactòriament en la reducció del conjunt d'ocultacions (400) registrades en el programa CALOP, i permet afrontar la reducció de futures campanyes d'observació massiva.
Quant a la interferometría speckle, s'ha ideat, desenvolupat, implementat i avaluat una nova tècnica d'observació CCD per a aquest tipus d'observacions d'alta resolució espacial. Éstà basada en el mètode d'adquisició drift scanning i permet mostrejar la intensitat de l'objecte dins de l'interval de coherència atmosfèrica. S'ha validat amb la mesura de 4 sistemes binaris d'òrbita coneguda. Els resultats de separació angular, angle de posició i diferència de magnitud estan d'acord amb els publicats per autors anteriors. La tècnica permet a pràcticament qualsevol observatori (professional o amateur) afrontar programes "speckle" amb propòsits de contribució científica. Finalment, s'ha ideat, implementat i validat una nova tècnica de autocalibració de dades speckle que permet estalviar temps d'observació.

Texto completoTiivistelmä Langattomien kanavien häipyminen, langattomien laitteiden akkujen rajallinen koko, käyttäjien käyttötarpeiden muutokset sekä lisääntyvän tiedonsiirron ja lyhyemmän viiveen vaatimukset luovat suuria haasteita tulevaisuuden langattomien verkkojen suunnitteluun. On välttämätöntä kehittää tehokkaita resurssien allokointialgoritmeja, jotka sopeutuvat verkkojen muutoksiin ja saavuttavat sekä tavoiteviiveen että tavoitedatanopeuden mahdollisimman pienellä tehon kulutuksella. Tässä väitöskirjassa esitetään uusia paradigmoja langattomille tietoliikenneverkoille. Dynaamisen ohjelmoinnin välineitä käytetään luomaan dynaamisia verkon stabiloivia resurssien allokointiratkaisuja virtuaalisille pilvipalveludatakeskuksille, käyttäjien yhteistyöverkoille ja heterogeenisille verkoille. Tarkkoja dynaamisen ohjelmoinnin välineitä käytetään kehittämään optimaalisia resurssien allokointi ja topologian kontrollointialgoritmeja näille jonojen ja häipyvien kanavien verkoille. Tämän lisäksi, estimoituja dynaamisen ohjelmoinnin välineitä käytetään luomaan uusia alioptimaalisia ratkaisuja. Yhtenäisiä systeemimalleja ja yhtenäisiä kontrollointiongelmia luodaan sekä toissijaisen ja ensisijaisen palvelun tuottajan kognitiivisille verkoille että tavallisille langattomille verkoille. Tulokset osoittavat että sopeutumalla jonojen pituuksien ja kanavien muutoksiin dynaaminen tekniikka vaimentaa ensisijaisen ja toissijaisen palvelun tuottajien kognitiivisten verkkojen vaikutusta toisiinsa. Tutkimme myös verkon stabiiliutta ja luomme uusia stabiilisuusalueita sekä ensisijaisen ja toissijaisen palveluntuottajan kognitiivisille verkoille että tavallisille langattomille verkoille. K:n askeleen Lyapunovin driftiä käytetään analysoimaan dynaamisen kontrollointitekniikan suorituskykyä ja stabiiliutta. Lisäksi uusi yhtenäinen stabiiliusanalyysi ja jonon yläraja luodaan ensisijaisen ja toissijaisen palveluntuottajan kognitiivisille verkoille ja tavallisille langattomille verkoille. Dynaamisen algoritmin näytetään stabiloivan verkko ja minimoivan keskimääräisen jonon pituuden yläraja sopeutumalla verkon olosuhteiden muutoksiin. Tämän lisäksi todistamme että aiemmin esitetty frame-algoritmi ei minimoi keskimääräisen viiveen ylärajaa, kun käyttäjät jakavat keskenään resursseja

Abstract: ABSTRACT The design of heterobimetallic luminescent complexes has gained growing interest in recent years due to their unique photophysical properties. More specifically, the development of heterobimetallic complexes using d - block chromophores to sensitize the near - infrared (NIR) emission of lanthanide complexes (such as Nd(III) and Yb(III)) has received significant attention taking into account their longer emission wavelengths and the interest of the NIR emission which pene trates human tissue more effectively than UV light. These properties give them potential applications in medical diagnostics or biomedical assays.

Le design de complexes luminescents hétérobimétalliques a suscité ces dernières années un intérêt croissant en raison de leurs propriétés photophysiques uniques. Dans ces complexes de lanthanide (Nd (III) et Yb (III)) associé à des chromophores du bloc d, la forte émission des métaux de transition dans le visible est utilisée pour sensibiliser de façon efficace les niveaux f-f des lanthanides(III) qui émettent à leur tour dans le visible ou l’IR selon les terres rares. Plus spécifiquement l’attention s’est focalisée sur le développement de complexes hétérobimétalliques d-f pour l’émission dans le proche infrarouge (NIR). En effet le proche infrarouge, comparé à l’UV, pénètre plus facilement les tissus biologiques humains notamment la peau. Bien que de telles propriétés confèrent à ces complexes bimétalliques un fort potentiel pour le diagnostic médical, aucun complexe hétérobimétallique d-f greffé de façon covalente à une matrice de silice n’a été décrit. Dans ce travail de nouveaux complexes hétérobimétalliques d-f contenant des ligands silylés ont été préparés et greffés sur la silice. Les complexes monomères [Ru(bpy)2(bpmd)]Cl2 (noté Ru), [Ru(bpy)(bpy-Si)(bpmd)]Cl2 (noté RuL) et [Ln(TTA-Si)3] (noté LnL3) et les complexes hétérobimétalliques d-f Ru-LnL3 et Ln-RuL (Ln = Nd3+, Yb3+) ont été préparés. La caractérisation des complexes a été effectuée par spectroscopie Raman, RMN 1H et 13C RMN. Les spectres RMN 1D 1H et 13C NMR ainsi que 2D de corrélation HSQC confirment les structures proposées. L’étude des propriétés photophysiques met en évidence l’émission de l’élément lanthanide dans le proche infrarouge ainsi que l'efficacité du processus de transfert d'énergie Ru-Ln qui est facilité par le ligand (2,2'-bipyrimidine). Les mesures de durée de vie et de rendement quantique (ET) pour le transfert d'énergie indiquent des valeurs remarquables comprises entre 30 et 84 %. La valeur du rendement quantique (ET) du complexe d'Yb-RuL, 73,4 %, est à ce jour la plus grande valeur rapportée pour un complexe hétérobimétallique Ru (II)-Yb (III). Le greffage sur différentes matrices de silice, mésoporeuse SiO2 ou dense SiO2 d, a été réalisé. Les nanohybrides SiO2-RuL, SiO2-NdL3 et SiO2-YbL3 ont été obtenus avec des taux de greffage allant de 0,08 à 0,18 mmol de complexe par gramme de silice. SiO2-RuNd et SiO2- RuYb ont été obtenus par greffage simultané des complexes silylés monomères de ruthénium et de lanthanide, des taux de greffage de 0,10 à 0,16 mmol.g-1 ont été obtenus, respectivement. Les rendements quantiques ET de transfert d’énergie des nanohybrides SiO2-RuNd et SiO2-RuYb sont respectivement de 40 and 27,5 %. La valeur remarquable obtenue pour le nanohybride impliquant le néodyme, SiO2-RuNd, s’explique par bonne adéquation entre les niveaux d’énergie du donneur et de l’accepteur. Les nanohybrides SiO2- RuYbL3, SiO2-YbRuL, SiO2d-YbRuL et SiO2-NdRuL ont été obtenus par greffage des complexes silylés hétérobimétallic d-f élaborés dans ce travail, les taux de greffage, de 0,03 à 0,17 mmol.g-1 permettent d’envisager une fonctionnalisation chimique ultérieure de ces nanoobjets. Les propriétés de luminescence de ces nanohybrides sont similaires à celles des complexes non greffés hormis pour SiO2-YbRuL and SiO2d-YbRuL qui présentent des profils de luminescence différents comparés au complexe libre Yb—RuL. Le greffage à l'intérieur des pores de la silice pourrait éviter le processus de désactivation de la luminescent contrairement au greffage sur la matrice de silice dense. Les propriétés photophysiques associées à la morphologie et à la stabilité de la matrice de silice mésoporeuse permettent d’envisager l’utilisation de ces nouveaux nanohybrides luminescents dans le proche infrarouge comme nanosondes ou nanomarqueurs de systèmes biologiques.
The design of heterobimetallic luminescent complexes has gained growing interest in recent years due to their unique photophysical properties. More specifically, the development of heterobimetallic complexes using d-block chromophores to sensitize the near-infrared (NIR) emission of lanthanide complexes (such as Nd(III) and Yb(III)) has received significant attention taking into account their longer emission wavelengths and the interest of the NIR emission which penetrates human tissue more effectively than UV light. These properties give them potential applications in medical diagnostics or biomedical assays. Transitions to excited state levels of transition metal complexes occurring in the visible and characterized by large absorption coefficients, could efficiently sensitize f-f levels of Ln(III) ions. In this work new d-f heterobimetallic complexes containing silylated ligands were prepared supported on silica materials. [Ru(bpy)2(bpmd)]Cl2 (labeled Ru), [Ru(bpy)(bpy-Si)(bpmd)]Cl2 (labeled RuL) and [Ln(TTA-Si)3] (labeled LnL3) and d-f heterobimetallic complexes, Ru—LnL3 and Ln—RuL (Ln = Nd3+, Yb3+) were prepared. Structural characterization was carried out by Raman Scattering, 1H and 13C NMR spectroscopies. Results obtained from 1H-13C HMBC and HSQC correlation NMR spectra confirm the formation of proposed complexes. Photophysical properties studies highlight the efficiency of Ru—Ln energy transfer processes in NIR-emitting lanthanide complexes mediated by conjugated bridging ligand (2,2'-bipyrimidine). Lifetime measurements were carried out and values of quantum yield for energy transfer (ET) between 30 and 84 % could be evaluated. ET of 73.4 % obtained for the Yb—RuL complex is the largest value reported for Ru(II)—Yb(III) heterobimetallic complexes so far. Grafting on different silica matrix was also demonstrated. SiO2-Ru, SiO2-NdL3 and SiO2-YbL3 nanohybrids were obtained with grafting efficiencies from 0.08 to 0.18 mmol g-1 of silica. SiO2-RuNd and SiO2-RuYb were performed from simultaneous grafting of ruthenium and lanthanides silylated complexes. Grafting efficiencies from 0.10 to 0.16 were obtained. ET of 40 and 27.5 % were obtained from SiO2-RuNd and SiO2-RuYb, respectively. The higher values observed for the Nd(III) nanohybrid is well explained by the matching of donor and acceptor energy levels. SiO2-RuYbL3, SiO2-YbRuL, SiO2 d-YbRuL and SiO2-NdRuL were carried out from grafting of d-f heterobimetallic silylated complexes. Grafting efficiencies from 0.03 to 0.17 were obtained. Luminescent properties from these nanohybrids were similar to the free complexes. However the SiO2-YbRuL and SiO2 d-YbRuL showed distinct luminescent profiles compared with the free Yb—RuL. The grafting inside the mesoporous channels may prevent luminescent desactivation processes comparing to the dense silica matrix. The photophysical properties associated with the morphology and stability of the mesoporous silica matrix allow suggesting these new NIR luminescent nanohybrids as nanoprobes or nanomarkers in biomedicine.

Texto completoEste trabajo trata de analizar el paisaje histórico del Valle de Àger (España) a través de múltiples fuentes, como las fuentes escritas, la teledetección, las fuentes arqueológicas, las arquitecturas históricas y los análisis del parcelario agrario, de la viabilidad y de la toponímica. El objetivo principal es el de analizar la periodización del asentamiento medieval de forma general y detallada a través del estudio del paisaje fortificado y del paisaje sagrado en una ventana cronológica que va desde el siglo 5 hasta el siglo 13. También se analizaron los elementos principales de las arquitecturas históricas disponibles mediante los métodos de la arqueología de la arquitectura. Otra aplicación metodológica fue la de la Archéogéographie Francesca a través de la cual es posible estudiar las estructuras del parcelario agrario y de la viabilidad. Todos los datos han sido sintetizados para obtener el cuadro general del asentamiento medieval en el valle.
This work deals with the analysis of the Ager Valley historic landscape through the methodologies of Landscape Archaeology. It uses several multidisciplinary sources as written documents, remote sensing images (mainly lidar and radar), parcels analysis, archaeological prospections and archaeological excavations. The main target has been obtaining the periodisation of the medieval settlement in the valley from the 5th to the 13th centuries. It analyses the structure of the agrarian parcel systems through the methodology developed in the Archaeogeographic studies and predictive archaeology (least cost path, viewshed analysis, site catchment analysis). It also uses the application of the Archaeology of Architecture in order to study the material evidences of the churches and the defensive towers of the valley. After the analysis of the different sources, it tries to develop a synthesis of the data following the chronological windows allowed by the sources. All the data have been used also to analyse the Landscape of Power and the Sacred Landscape in the valley during the Middle Ages.
