With the advent of techniques such as AJAX, the bar has been raised for what users have come to expect from web applications. However, although web application development often starts off simple, limitations in the web programming model might start to show when the business requirements become more complex. To successfully implement large-scale web application, software developers need to have knowledge of a big set of complementary technologies. This thesis describes the implementation of a prototype of a central hotel property management system using web technologies. These technologies are then compared to an alternative set of technologies, which are used for implementing a second prototype; a stand-alone desktop client distributed using Java Web Start. The thesis highlights some of the current problems with the web programming model and shows how the user experience can be improved by instead using desktop technologies.

Le traitement automatique de la parole est un domaine qui englobe un grand nombre de travaux : de la reconnaissance automatique du locuteur à la détection des entités nommées en passant par la transcription en mots du signal audio. Les techniques de traitement automatique de la parole permettent d’extraire nombre d’informations des documents audio (réunions, émissions, etc.) comme la transcription, certaines annotations (le type d’émission, les lieux cités, etc.) ou encore des informations relatives aux locuteurs (changement de locuteur, genre du locuteur). Toutes ces informations peuvent être exploitées par des techniques d’indexation automatique qui vont permettre d’indexer de grandes collections de documents. Les travaux présentés dans cette thèse s’intéressent à l’indexation automatique de locuteurs dans des documents audio en français. Plus précisément nous cherchons à identifier les différentes interventions d’un locuteur ainsi qu’à les nommer par leur prénom et leur nom. Ce processus est connu sous le nom d’identification nommée du locuteur (INL). La particularité de ces travaux réside dans l’utilisation conjointe du signal audio et de sa transcription en mots pour nommer les locuteurs d’un document. Le prénom et le nom de chacun des locuteurs est extrait du document lui même (de sa transcription enrichie plus exactement), avant d’être affecté à un des locuteurs du document. Nous commençons par rappeler le contexte et les précédents travaux réalisés sur l’INL avant de présenter Milesin, le système développé lors de cette thèse. L’apport de ces travaux réside tout d’abord dans l’utilisation d’un détecteur automatique d’entités nommées (LIA_NE) pour extraire les couples prénom / nom de la transcription. Ensuite, ils s’appuient sur la théorie des fonctions de croyance pour réaliser l’affectation aux locuteurs du document et prennent ainsi en compte les différents conflits qui peuvent apparaître. Pour finir, un algorithme optimal d’affectation est proposé. Ce système obtient un taux d’erreur compris entre 12 et 20 % sur des transcriptions de référence (réalisées manuellement) en fonction du corpus utilisé. Nous présentons ensuite les avancées réalisées et les limites mises en avant par ces travaux. Nous proposons notamment une première étude de l’impact de l’utilisation de transcriptions entièrement automatiques sur Milesin. / The automatic processing of speech is an area that encompasses a large number of works : speaker recognition, named entities detection or transcription of the audio signal into words. Automatic speech processing techniques can extract number of information from audio documents (meetings, shows, etc..) such as transcription, some annotations (the type of show, the places listed, etc..) or even information concerning speakers (speaker change, gender of speaker). All this information can be exploited by automatic indexing techniques which will allow indexing of large document collections. The work presented in this thesis are interested in the automatic indexing of speakers in french audio documents. Specifically we try to identify the various contributions of a speaker and nominate them by their first and last name. This process is known as named identification of the speaker. The particularity of this work lies in the joint use of audio and its transcript to name the speakers of a document. The first and last name of each speaker is extracted from the document itself (from its rich transcription more accurately), before being assigned to one of the speakers of the document. We begin by describing the context and previous work on the speaker named identification process before submitting Milesin, the system developed during this thesis. The contribution of this work lies firstly in the use of an automatic detector of named entities (LIA_NE) to extract the first name / last name of the transcript. Afterwards, they rely on the theory of belief functions to perform the assignment to the speakers of the document and thus take into account the various conflicts that may arise. Finally, an optimal assignment algorithm is proposed. This system gives an error rate of between 12 and 20 % on reference transcripts (done manually) based on the corpus used.We then present the advances and limitations highlighted by this work.We propose an initial study of the impact of the use of fully automatic transcriptions on Milesin.

Rich Internet Applications (RIAs) have been widely used in the web over the last decade as they were found to be responsive and user-friendly compared to traditional web applications. RIAs use client-side scripting such as JavaScript which allows for asynchronous updates on the server-side using AJAX (Asynchronous JavaScript and XML). Due to the large size of RIAs and therefore the long time required for crawling, distributed RIA crawling has been introduced with the aim to decrease the crawling time. However, the current RIA crawling systems are not scalable, i.e. they are limited to a relatively low number of crawlers. Furthermore, they do not allow for fault tolerance in case that a failure occurs in one of their components. In this research, we address the scalability and resilience problems when crawling RIAs in a distributed environment and we explore the possibilities of designing an efficient RIA crawling system that is scalable and fault-tolerant. Our approach is to partition the search space among several storage devices (distributed databases) over a peer-to-peer (P2P) network where each database is responsible for storing only a portion of the RIA graph. This makes the distributed data structure invulnerable to a single point of failure. However, accessing the distributed data required by crawlers makes the crawling task challenging when the number of crawlers becomes high. We show by simulation results and analytical reasoning that our system is scalable and fault-tolerant. Furthermore, simulation results show that the crawling time using the P2P crawling system is significantly faster than the crawling time using both the non-distributed crawling system and the distributed crawling system using a single database.

Urofacial syndrome (UFS; MIM# 236730) is a rare autosomal recessive condition characterised by urinary bladder and bowel voiding dysfunction with a pathognomonic abnormality of facial movement with expression. UFS can be caused by biallelic putative loss-of-function mutations in HPSE2, which encodes heparanase 2. Failure to discover HPSE2 mutations in all cases of UFS suggests genetic heterogeneity. The urinary tract features of UFS overlap those seen in the spectrum of non-syndromic non-neurogenic voiding dysfunction and vesicoureteric reflux (VUR). This overlap suggests there may be some aspects of pathogenesis in common. The project aimed to define the genotypic and phenotypic spectrum associated with mutations in HPSE2 by Sanger sequencing and multiplex ligation-dependent probe amplification (MPLA) in newly referred cases of UFS and making comparison to a review of mutations and phenotypes seen in the literature. This work discovered five further families with HPSE2 associated UFS increasing known mutations whilst, reinforced that this is an under-recognised condition and emphasised the previously under-reported feature of facial weakness. The failure to discover HPSE2 mutations in all cases referred provided further evidence of genetic heterogeneity. The project also aimed to discover further genes associated with UFS. Autozygosity mapping and whole exome sequencing was carried out in cases of UFS without mutations in HPSE2. This led to the recognition that UFS is also caused by biallelic putative loss-of-function mutations in LRIG2 encoding the leucine-rich repeats and immunoglobulin-like domains 2 (LRIG2) protein in three families. Failure to identify LRIG2 mutations in all HPSE2 negative families suggests further genetic heterogeneity. To address the question of whether the pathogenesis of UFS overlaps more common conditions with a similar spectrum of urinary tract abnormalities I aimed to examine whether pathogenic variants in HPSE2 and LRIG2 were seen in these phenotypes. Unexpectedly this led to the discovering of further families affected by UFS but failed to show an association of variants in UFS genes with non-syndromic urinary tract abnormalities. However, variants of potential interest were discovered. As part of work toward understanding the pathogenesis of UFS and designing a model to test the pathogenesis of sequence variants expression studies in a Xenopus tropicalis hpse2 knock-down model of UFS were carried out. The knock-down model provided valuable insight in to the likely pathogenesis of UFS with evidence pointing towards a congenital peripheral neuropathy with failure of correct nerve path finding. Understanding the pathogenesis of UFS has the potential to direct further research in to therapeutic intervention.

O PRP é um produto autólogo obtido do sangue total (WB). O ácido hialurônico é um glicosaminoglicano e principal componente do fluido sinovial. A quitosana é um polissacarídeo natural encontrado principalmente na carapaça de crustáceos. O PRP puro (P-PRP, rico em plaquetas e pobre em leucócitos) foi obtido a partir da centrifugação controlada do WB, e ativado com os agonistas soro autólogo e cálcio. Os scaffolds foram estruturados em micropartículas ou esponjas, para atender os requisitos de formulações injetáveis ou sólidas, respectivamente. Nesse contexto, os seguintes scaffolds foram preparados e caracterizados: sólidos porosos (esponjas) de quitosana não estabilizados (PCHTs) e estabilizados (SPCHTs); micropartículas de quitosana-tripolifosfato de sódio (iCHT-TPPs); micropartículas e esponjas de ácido hialurônico autorreticulado (ACPs) e de ácido hialurônico reticulado com 1,4-butanodiol diglicidil éter (HA-BDDE); e esponjas e micropartículas de ACP e CHT (PECs). PCHTs foram preparados por congelamento e liofilização de soluções de CHT, variando a concentração e as condições de congelamento. As estabilizações foram realizadas pelo tratamento dos PCHTs com hidróxido de sódio, série de etanol ou reticulação com tripolifosfato. Os iCHT-TPPs foram preparados por reticulação iônica de quitosana com TPP em diferentes razões mássicas. ACPs foram obtidos por autoesterificação organocatalisada. HA-BDDE foi preparado por eterificação dos grupos hidroxílicos do HA com o epóxido BDDE. PECs foram preparados por reticulação iônica do ACP com a CHT. Para a preparação de scaffolds compósitos, P-PRP ativado contendo h-AdMSCs foi imediatamente pipetado sobre a superfície dos scaffolds. Os resultados mostraram que os scaffolds não apresentam citotoxicidade. Micrografias obtidas por microscopia eletrônica de varredura mostraram compatibilidade estrutural com as redes de fibrina formadas no interior dos poros ou na superfície de scaffolds compósitos. Os scaffolds compósitos estimularam o crescimento de h-AdMSCs e a diferenciação osteogênica. Os scaffolds compósitos também promoveram liberação gradual dos fatores de crescimento PDGF-AB e TGF-?1. Assim, concluímos que os scaffolds compósitos estudados neste trabalho são promissores para engenharia de tecidos, particularmente para a cicatrização e regeneração óssea, no âmbito da medicina regenerativa / Abstract: This work aimed to study the in vitro performance of platelet-rich plasma (PRP) with scaffolds of hyaluronic acid (HA) and/ or chitosan (CHT) as a composite scaffold for proliferation and osteogenic differentiation of human adipose-derived mesenchymal stem cells (h-AdMSCs). The PRP is an autologous product obtained from whole blood (WB). Hyaluronic acid is a glycosaminoglycan and the main component of the synovial fluid. Chitosan is a natural polysaccharide found mainly in the carapace of crustaceans. The pure PRP (P-PRP, rich in platelet and poor in leukocytes) was obtained from controlled centrifugation of WB, and activated with the agonists autologous serum and calcium. The scaffolds were structured in microparticles or sponges, to comply the requirements of injectable or solid formulations, respectively. In this context, the following scaffolds were prepared and characterized: chitosan porous solid (sponge) unstabilized (PCHTs) and stabilized (SPCHTs); chitosan-sodium tripolyphosphate microparticles (iCHT-TPPs); microparticles and sponges of auto-crosslinked hyaluronic acid (ACPs) and of hyaluronic acid crosslinked with 1,4-butanediol diglycidyl ether (HA-BDDE); and microparticles and sponges of ACP and CHT (PECs). PCHTs were prepared by freezing and lyophilization of CHT solutions, varying the concentration and freezing conditions. Stabilization was performed by treating the PCHTs with sodium hydroxide, an ethanol series or by crosslinking with tripolyphosphate. The iCHT-TPPs were prepared by ionic crosslinking of chitosan with TPP at different mass ratios. ACPs was prepared by organocatalyzed auto-esterification. HA-BDDE was prepared by etherification of the hydroxyl groups of HA with the epoxide BDDE. PECs were prepared by ionic crosslinking of ACP with CHT. For the preparation of composite scaffolds, activated P-PRP containing h-AdMSCs was immediately pipetted onto the surface of the scaffolds. The results showed that the scaffolds do not exhibit cytotoxicity. Micrographs obtained by scanning electron microscopy (SEM) showed structural compatibility with fibrin networks formed inside the pores or on the surface of scaffolds. The composite scaffolds stimulated the growth of h-AdMSCs and osteogenic differentiation. Composite scaffolds also promoted gradual release of growth factors PDGF-AB and TGF-?1 and osteogenic differentiation. Thus, we conclude that the composite scaffolds studied in this work are promising for tissue engineering, particularly for healing and bone regeneration in regenerative medicine / Doutorado / Engenharia Química / Doutora em Engenharia Quimica

A cicatrização das lesões ligamentares é lenta e muitas vezes ineficiente. Uma vez lesado, o ligamento suspensor do boleto (LSB) dificilmente recupera suas propriedades biomecânicas originais. A desmite do LSB proximal dos membros torácicos ocorre em cavalos de todas as raças e todas as disciplinas esportivas. O objetivo deste trabalho foi avaliar clinicamente e por ultrassonografia, a influência do plasma rico em plaquetas (PRP), e do PRP associado ao LASER terapêutico, na cicatrização da região proximal do LSB, em cavalos com desmite induzida por colagenase. Para isto foram utilizados 18 animais sem raça definida, distribuídos em três grupos. O G1 foi formado por seis animais, submetidos a indução da desmite na região proximal do LSB, que não receberam qualquer tratamento. O G2 foi formado por seis animais, que foram submetidos a desmite induzida e após três semanas receberam aplicação intralesional de PRP guiada pelo ultrassom. O G3 foi formado por seis animais, que após indução da desmite receberam tratamento com LASER terapêutico a partir da segunda semana, e na terceira semana pós-lesão receberam aplicação intralesional de PRP guiada pelo ultrassom. A indução da desmite foi realizada por meio de infiltração guiada pelo ultrassom na região proximal do LSB, sendo este considerado o tempo 0. A cada semana e até a semana oito, os cavalos foram avaliados clinicamente, por ultrassonografia e por análise cinemática, ao trote em linha reta. Houve diferença significativa na comparação entre grupos para as variáveis aumento de volume na avaliação clínica, e área no corte transversal do ligamento e, área no corte transversal da lesão na avaliação ultrassonográfica. Na comparação entre os diferentes momentos de observação as variáveis aumento de volume e dor à palpação do G2 e G3 mostraram escores maiores quando comparados ao G1, sendo que o G2 apresentou escore maior que o G3. Ultrassonograficamente, a ecogenicidade da lesão mostrou diminuição dos escores, a partir da quinta semana de avaliação nos grupos tratados. As demais variáveis clínicas ou ultrassonográficas, bem como a análise cinemática da claudicação não mostraram diferenças significativas entre os grupos. O PRP, apesar de ocasionar inflamação leve e transitório após infiltração, influenciou positivamente o processo de cicatrização da parte proximal do LSB, com um efeito analgésico adicional quando associado ao LASER terapêutico. / The healing process of injured ligaments is slow and often inefficient. Once damaged the suspensory ligament (SL) hardly recover their original biomechanical properties. The forelimb proximal suspensory ligament desmitis occurs in horses of all breeds and all sports. The aim of this study was to evaluate clinically and ultrasonographically, the influence of platelet-rich plasma (PRP), and PRP associated with LASER therapy, on the healing process of the proximal region of the SL in horses with collagenase-induced demitis. For this purpose it were used 18 cross breed horses divided into 3 groups. G1 was composed of six horses subjected to induction of proximal suspensory desmitis, with no treatment. G2 was composed of six horses subjected to desmitis induction and after three weeks they received ultrasound-guided intralesional injection of PRP. G3 was composed of six horses subjected to desmitis induction and after two weeks they received laser therapy and one week later they received intralesional guided-ultrasound injection of PRP. Induction of desmitis was made using ultrasound-guided infiltration in PSL, which was considered day zero. Horses were evaluated clinically, in straight line trot for cinematic analysis and ultrasonographically, every week until eighth week. There were significant difference between groups for swelling, the cross-sectional area of the ligament, and the cross-sectional area of the injury on ultrasound evaluation. Comparing the different times of observation, descriptively were a difference for G2 and G3 in the clinical variables that evaluated swelling and pain on palpation, showed higher scores compared to the G1, and G2 had higher scores than the G3. Sonographically, the echogenicity of the lesion showed decreased scores from the fifth week of evaluation in the treated groups. The other clinical variables or ultrasound, as well as the kinematic analysis of lameness showed no significant differences between groups. PRP, although causing transient and mild inflammation after infiltration, positively influenced the healing process of the proximal part of the SL, with additional analgesic effect when combined with laser therapy.

Macroscopicamente foi evidente a cicatrização precoce da ferida tratada com PRP gel autólogo em relação à controle, o que também foi comprovado nas análises histológicas. Concluiu-se que o PRP é eficaz e acelera o processo de cicatrização, quando aplicado em intervalos curtos e de forma seriada, comprovando seu potencial terapêutico sobre lesões cutâneas. Pode ainda ser uma alternativa de tratamento de feridas.

However, some situations make it impossible to use this source, should be considered as alternatives to PRP homologous or heterologous. Aiming to evaluate the effect of platelet-rich plasma (PRP) in autologous, heterologous and homologous form gel on cutaneous wound healing in vivo, 24 rabbits (9 males and 9 females) divided into three groups were used for the experiment and 6 animals (3 males and 3 females) were donors PRP. For the heterologous group, used a dog, adult mongrel to obtain PRP. The lesions were performed using a punch of 8 mm, and the right side was treated with 0.9% NaCl ® (A) and left side (B) applied PRP gel (GA = autologous, GHE=heterologous, and GHO = homologous). Lesions were evaluated for a period of 17 days. On days 0, 3, 7, 10, 14 and 17 animals were clinically evaluated by weight and pain, and on day 17 biopsies were taken for histopathological assessment of wounds. The percentage of contraction was evident in side B (treated) in all groups, which was also confirmed in the microscopic analysis of histological sections. Thus, it was concluded that the PRP, regardless of source, improves and accelerates the healing process, demonstrating their therapeutic potential on skin lesions and can be used in patients with impaired wound healing. / Ao longo dos anos, o plasma rico em plaquetas (PRP) autólogo tem sido utilizado com grandes vantagens na cicatrização de feridas agudas e crônicas.

Com o objetivo de avaliar o efeito do plasma rico em plaquetas (PRP) na forma gel autólogo, heterólogo e homólogo sobre a cicatrização de feridas cutâneas in vivo, foram utilizados 24 coelhos (9 machos e 9 fêmeas) divididos em 3 grupos para o experimento e 6 animais (3 machos e 3 fêmeas) foram doadores de PRP. Para o grupo heterólogo, utilizou-se um cão, adulto, sem raça definida para obtenção do PRP. As lesões foram feitas com auxílio de um punch de 8 mm, sendo que o lado direito foi tratado com NaCl 0,9%® (A) e o lado esquerdo (B) aplicado gel de PRP (GA=autólogo; GHE=heterólogo e GHO=homólogo). As lesões foram avaliadas por um período de 17 dias. Nos dias 0, 3, 7, 10, 14 e 17 os animais foram avaliados clinicamente por meio de peso e dor, e no 17º dia foi feita biópsia para avaliação histopatológica das feridas. O percentual de contração foi evidente no lado B (tratado), o que também foi comprovado nas análises microscópicas dos cortes histológicos. Com isso, concluiu-se que o PRP, independente da fonte, melhora e acelera o processo de cicatrização, comprovando seu potencial terapêutico sobre as lesões cutâneas, podendo ser utilizado em pacientes com dificuldades de cicatrização.
