Abstract:
The semi-analytical method, widely used for calculating derivatives of static response with respect to design variables for structures modeled by finite elements, is studied in this research. The research shows that the method can have serious accuracy problems for shape design variables in structures modeled by beam, plate, truss, frame, and solid elements. Local and global indices are developed to test the accuracy of the semi-analytical method. The local indices provide insight into the problem of large errors for the semi-analytical method. Local error magnification indices are developed for beam and plane truss structures, and several examples showing the severity of the problem are presented. The global index provides us with a general method for checking the accuracy of the semi-analytical method for any type of model. It characterizes the difference in errors between a general finite-difference method and the semi-analytical method. Moreover, a method improving the accuracy of the semi-analytical method (when possible) is provided. Examples are presented showing the use of the global index.

Abstract:
Shape data encompass all the information that is left to describe a shape following removal of location, rotation and scale effects. Much work has been done in the analysis of two-dimensional shapes depicted by anatomical landmarks placed at points of importance. Less has been carried out in the area of three-dimensional shapes, particularly in terms of growth or change over time. This thesis considers the analysis of such longitudinal three-dimensional shape data. In doing so, two well established but normally unrelated areas of Statistics are brought together: those of longitudinal data analysis (specifically, linear mixed effects models) and shape analysis. A recently proposed method of analysing longitudinal high-dimensional data is presented in a novel application within the area of shape analysis, illustrated by a study comparing the facial shapes of cleft-lip and palate children with controls as they grow from three months to two years of age. Both anatomical landmarks and facial curves are considered. Chapter 1 broadly introduces the areas of shape analysis, linear mixed effects models and dimension reduction. Standard methods for measuring shapes are introduced, along with the difficulties inherent in analysing the resulting data. A broad overview of the methods of aligning individual shapes to remove the unwanted effects of location, rotation and scale is given, along with related geometrical issues in terms of the high-dimensional space in which a set of shapes resides. A general introduction to linear mixed effects models compares and contrasts them with simple linear models, explaining the reasons behind using them and presenting the different specifications of the conditional and marginal models. The area of dimension reduction is touched upon, specifically introducing B-splines and principal components analysis, with reference to the analysis of curves consisting of many points at small increments to one another. The data from the cleft-lip and palate study are introduced, along with a discussion of the primary interest of the analysis and the issue of missing data. Chapter 2 presents the statistical definition of a shape and introduces the area of statistical shape analysis in detail, specifically presenting the technicalities of shape space and distances, and methods such as Procrustes alignment of a set of shapes to remove unwanted effects. The concept of tangent coordinates is introduced as a projection of shape data into a Euclidean space, to enable the use of multivariate methods, and an outline given of thin-plate splines and deformations for the analysis of surfaces. Recent literature in the area of shape analysis is presented. Further recent literature addressing the modelling of growth in shapes is presented in Chapter 3, which goes on to discuss the use of linear mixed models on univariate and multivariate longitudinal data. The difficulties of applying mixed models to multivariate data are discussed and a recently proposed alternative method introduced, which involves fitting mixed models to the responses on pairs of outcomes rather than the full set. A description of the R function written as part of this thesis to fit such pairwise models follows, and this is applied to simulated triangles and quadrilaterals as an illustration. The initial application of the pairwise method to the cleft-lip and palate landmark data is presented in Chapter 4. The landmarks are described and the models are fitted to the tangent coordinate responses with different covariance structures for the random effects. The problems that arise and the deficiencies of the fitted models are extensively discussed. Chapter 5 goes on to address the issues raised in Chapter 4. A method of aligning the individual shapes based upon a subset of landmarks is suggested, along with a model that assumes independence of coordinates between dimensions but correlation within, and the benefits of these approaches compared. A simulation study is carried out to investigate the reasons behind and effects of random effects correlations that are estimated as being close to one, concluding that the problem lies in small variances that are poorly estimated, but that this is unlikely to be of severe detriment to the fixed effects estimates. A method of taking the principal components of the tangent coordinates is suggested, where the model responses are the principal components scores, and this proves to be the most appropriate way of applying the pairwise models in terms of model fit and computational efficiency. In Chapter 6, recent literature on the topic of curve analysis is presented, along with the way the facial curves are measured and the need for dimension reduction. Two methods are presented to this end: B-splines and principal components analysis, with the former suffering similar problems to the landmark analyses in terms of poorly estimated random effects variances, and the latter proving more successful. The application of the pairwise models to the principal components scores of the tangent coordinates provides a detailed analysis of the cleft-lip and palate data. Issues surrounding model comparison are addressed in Chapter 7, with several hypothesis tests presented and applied to simulated data. Drawbacks with some of the tests when applied to high dimensional or longitudinal data result in poor performance, but a method suggested by Faraway (1997) and a modification of the likelihood ratio test, both using bootstrapping, show similarly successful results. These are subsequently used to test for any differences in the time trends for the cleft and control groups post-surgery and find that there are significant differences. Condensed forms of this thesis have been presented at invited seminars and international conferences, and may be found in published form in Barry & Bowman (2006), Barry & Bowman (2007) and Barry & Bowman (2008).

Abstract:
This thesis describes methods for reconstruction in non-linear tomography applications. The specific example application in this thesis is Optical Tomography (OT), which seeks the recovery of optical properties such as absorption, scattering and refractive index, given measurements of transmitted light through biological tissue of several centimetres in thickness. Previous methods pose such a problem as the optimisation of a model fitting procedure over a space of piecewise local basis functions such as pixels (or voxels in 3D). We employ a parametrisation of closed surfaces using spherical harmonics based on constrained minimisation of the distortions occurring by the mapping of the surfaces, acquired from voxel images, to a unit sphere. This method could be used to describe parametrically any closed surface, and overcomes the restriction to just star-shaped objects that is commonly found in literature. A surface meshing algorithm is proposed by applying the parametrisation to map regular surface meshes initially defined on the a unit sphere, by tessellation of an embedded icosahedron, upon the parametrically defined surfaces. This procedure creates regular sampled meshes which is a prerequisite for a good discretisation of a surface, in an automatic procedure. A Boundary Element Method for OT is constructed, for the solution of the diffusion equation on realistic geometrical models, constructed from segmented Magnetic Resonance Images (MRI) or Computed Tomography (CT) scans. In this work we propose a method for reconstruction of the boundaries of piecewise constant regions. The shape description for closed surfaces is used in a novel shape estimation inverse problem in 3D using OT measurements, based on a forward solution constructed from BEM and the regular meshes. Some examples are given that portray the capabilities of the proposed method.

Abstract:

The thesis presents a three dimensional shape optimization program which analyzes models made up of linear isoparametric elements. The goal of the program is to achieve a near uniform model stress state and thereby to minimize material volume.

The algorithm is iterative, and performs two analyses per iteration. The first analysis is a static stress analysis of the model for one or more load cases. Based on results from the static analysis, an expansion analysis is performed. Model elements are expanded or contracted based on whether they are stressed higher or lower than a reference stress. The shape changing is done by creating an expansion load vector using the differences between the calculated element stresses and the reference stress. Expansion displacements are solved for, and instead of using them to calculate stresses, the displacements are added to the nodal coordinates to reshape the structure. This process continues until a user defined convergence tolerance is met.

Four programs were used for the analysis process. Models were created using a finite element modeling program called I-IDEAS or CAIEDS. The I-IDEAS output files were converted to input files for the optimizer by a conversion program. The model was optimized using the shape optimization process described above. Post- processing was done using a program written with a graphical programming language called graPHIGS.

Models used to test the program were: a cylindrical pressure vessel with nonuniform thickness, a spherical pressure vessel with non-uniform thickness, a torque arm, and a draft sill casting o a railroad hopper car. Results were compared to similar studies from selected references.

Both pressure vessels converged to near uniform thicknesses, which compared ell with the reference work. In a two dimensional analysis, the torque arm volume decreased 24 percent, which compared well with published results. A three dimensional analysis showed a volume reduction of l3 percent, but there were convergence problems. Finally, the draft sill casting was reduced in volume by 9 percent from a manually optimized design.

Abstract:
Fundamental processes in development and physiology are determined by the three-dimensional architecture of epithelial sheets. How these sheets deform and fold into complex structures has remained unclear, however, because their mechanical properties in three-dimensions have not been accessed experimentally. By combining measurements of epithelial tension, shape, and luminal pressure with mathematical modeling, here we show that epithelial cell sheets are active superelastic materials. We develop a new approach to produce massive arrays of epithelial domes with controlled basal shape and size. By measuring 3D deformations of the substrate and curvature of the dome we obtain a direct measurement of luminal pressure and epithelial tension. Observations over time-scales of hours allow us to map the epithelial tension-strain response, revealing a tensional plateau over several-fold areal strain reaching 300%. We show that these extreme nominal strains are accommodated by a highly heterogeneous stretching of individual cells, with barely deformed cells coexisting with others reaching 1000% areal strain, in seeming contradiction with the measured tensional uniformity. This phenomenology is reminiscent of superelasticity, a mechanical response generally attributed to microscopic material instabilities in metal alloys. We provide evidence that this instability is triggered in epithelial cells by a stretch-induced dilution of the actin cortex and rescued by the intermediate filament network. Finally, we implement a mathematical model that captures both the tension/strain relationship and strain heterogeneity. Our study unveils a new type of mechanical behavior -active superelasticity- that enables epithelial sheets to sustain extreme stretching under constant tension.
Els processos fonamentals en desenvolupament i en fisiologia estan determinats per l’estructura tridimensional dels teixits epitelials. Tot i així, l’explicació de com aquests teixits es deformen i es repleguen formant estructures complexes ha restat incerta perquè les seves propietats mecàniques en tres dimensions eren inaccessibles de forma experimental. Mitjançant la combinació de mesures de la tensió epitelial, de la forma i de la pressió luminal amb modelatge matemàtic, mostrem que els teixits de cèl·lules epitelials són materials superelàstics actius. Desenvolupem un nou mètode per produir de forma massiva matrius de doms epitelials (teixit epitelial en forma de cúpula) controlant a la vegada la seva forma i mida a la base. A partir de la mesura de les deformacions tridimensionals del substrat i de la mesura de la curvatura dels doms, obtenim una mesura directa de la pressió luminal i de la tensió epitelial. Amb observacions en escales temporals d’hores podem fer el mapatge de la relació tensió-deformació epitelial, que revela que la tensió es fa constant mentre l’àrea augmenta i es multiplica unes quantes vegades fins arribar a una deformació areal del 300%. Mostrem que aquestes deformacions nominals extremes són acomodades per una deformació de les cèl·lules individuals que és molt heterogènia, amb cèl·lules lleugerament deformades que coexisteixen amb altres que assoleixen el 1000% de deformació areal, aparentment en contradicció amb la uniformitat de la tensió mesurada. Aquesta fenomenologia evoca la superelasticitat, que és un comportament mecànic que s’atribueix generalment a inestabilitats materials microscòpiques en alguns aliatges metàl·lics. Aportem evidències que, en les cèl·lules epitelials, aquesta inestabilitat està desencadenada per una dilució del còrtex d’actina induïda per la deformació i limitada per la xarxa de filaments intermedis. Finalment, implementem un model matemàtic que captura a la vegada la relació tensió-deformació i l’heterogeneïtat en la deformació. El nostre estudi revela un nou tipus de comportament mecànic -la superelasticitat activa- que permet als teixits epitelials poder suportar deformacions extremes mantenint la tensió constant.

Abstract:
Las enfermedades cardiovasculares (ECVs) son la principal causa de mortalidad en el mundo Occidental. El interés de prevenir y tratar las ECVs ha desencadenado un rápido desarrollo de los sistemas de adquisición de imágenes médicas. Por este motivo, la cantidad de datos de imagen recolectados en las instituciones de salud se ha incrementado considerablemente. Este hecho ha aumentado la necesidad de herramientas automatizadas para dar soporte al diagnóstico, mediante una interpretación de imagen confiable y reproducible. La tarea de interpretación requiere traducir los datos crudos de imagen en parámetros cuantitativos, los cuales son considerados relevantes para clasificar la condición cardiaca de un paciente. Para realizar tal tarea, los métodos basados en modelos estadísticos de forma han recibido favoritismo dada la naturaleza tridimensional (o 3D+t) de las imágenes cardiovasculares. Deformando el modelo estadístico de forma a la imagen de un paciente, el corazón puede analizarse de manera integral. Actualmente, el campo de las imágenes cardiovasculares esta constituido por diferentes modalidades. Cada modalidad explota diferentes fenómenos físicos, lo cual nos permite observar el órgano cardiaco desde diferentes ángulos. El personal clínico recopila todas estas piezas de información y las ensambla mentalmente en un modelo integral. Este modelo integral incluye información anatómica y funcional que muestra un cuadro completo del corazón del paciente. Es de alto interés transformar este modelo mental en un modelo computacional capaz de integrar la información de manera global. La generación de un modelo como tal no es simplemente un reto de visualización. Requiere una metodología capaz de extraer los parámetros cuantitativos relevantes basados en los mismos principios técnicos. Esto nos asegura que las mediciones se pueden comparar directamente. Tal metodología debe ser capaz de: 1) segmentar con precisión las cavidades cardiacas a partir de datos multimodales, 2) proporcionar un marco de referencia único para integrar múltiples fuentes de información, y 3) asistir la clasificación de la condición cardiaca del paciente. Esta tesis se basa en que los modelos estadísticos de forma, y en particular los Modelos Activos de Forma, son un método robusto y preciso con el potencial de incluir todos estos requerimientos. Para procesar múltiples modalidades de imagen, separamos la información estadística de forma de la información de apariencia. Obtenemos la información estadística de forma a partir de una modalidad de alta resolución y aprendemos la apariencia simulando la física de adquisición de otras modalidades. Las contribuciones de esta tesis pueden ser resumidas así: 1) un método genérico para construir automáticamente modelos de intensidad para los Modelos Activos de Forma simulando la física de adquisición de la modalidad en cuestión, 2) la primera extensión de un simulador de Resonancia Magnética Nuclear diseñado para producir estudios cardiacos realistas, y 3) un método novedoso para el entrenamiento automático de modelos de intensidad y de fiabilidad aplicado a estudios cardiacos de Resonancia Magnética Nuclear. Cada una de estas contribuciones representa un artículo publicado o enviado a una revista técnica internacional.
Cardiovascular diseases (CVDs) are the major cause of death in the Western world. The desire to prevent and treat CVDs has triggered a rapid development of medical imaging systems. As a consequence, the amount of imaging data collected in health care institutions has increased considerably. This fact has raised the need for automated analysis tools to support diagnosis with reliable and reproducible image interpretation. The interpretation task requires to translate raw imaging data into quantitative parameters, which are considered relevant to classify the patient’s cardiac condition. To achieve this task, statistical shape model approaches have found favoritism given the 3D (or 3D+t) nature of cardiovascular imaging datasets. By deforming the statistical shape model to image data from a patient, the heart can be analyzed in a more holistic way. Currently, the field of cardiovascular imaging is constituted by different modalities. Each modality exploits distinct physical phenomena, which allows us to observe the cardiac organ from different angles. Clinicians collect all these pieces of information to form an integrated mental model. The mental model includes anatomical and functional information to display a full picture of the patient’s heart. It is highly desirable to transform this mental model into a computational model able to integrate the information in a comprehensive manner. Generating such a model is not simply a visualization challenge. It requires having a methodology able to extract relevant quantitative parameters by applying the same principle. This assures that the measurements are directly comparable. Such a methodology should be able to: 1) accurately segment the cardiac cavities from multimodal datasets, 2) provide a unified frame of reference to integrate multiple information sources, and 3) aid the classification of a patient’s cardiac condition. This thesis builds upon the idea that statistical shape models, in particular Active Shape Models, are a robust and accurate approach with the potential to incorporate all these requirements. In order to handle multiple image modalities, we separate the statistical shape information from the appearance information. We obtain the statistical shape information from a high resolution modality and include the appearance information by simulating the physics of acquisition of other modalities. The contributions of this thesis can be summarized as: 1) a generic method to automatically construct intensity models for Active Shape Models based on simulating the physics of acquisition of the given imaging modality, 2) the first extension of a Magnetic Resonance Imaging (MRI) simulator tailored to produce realistic cardiac images, and 3) a novel automatic intensity model and reliability training strategy applied to cardiac MRI studies. Each of these contributions represents an article published or submitted to a peer-review archival journal.

Abstract:
The objective of this thesis is to automate the manual 2D-patterned cutting of lace with high a accuracy and quality of the cutting edges. Four main problems for automating the cutting method were addressed; feature recognition technique for cutting path extraction, material handling system, laser beam manipulation and trajectory planning generation. An integrated mechatronic approach for designing the automated laser cutting system was outlined. The features of the 2D-patterned lace fabrics are not exactly identical and easily distorted nonlinearly due to handling operations. An active template matching technique was developed and implemented to recognise the distorted features of the 2D-patterned shape cuttings. To accommodate the geometrical pattern variations, the cutting paths of the 2D-patterned shapes were extracted using either the chain-coding technique or the binary morphological techniques.

Abstract:
Many clinically important applications require measurements on a large portion of the human body surface that may not be visible from a single view. For example, a single view may be insufficient for the measurement of a complete facial surface for facial plastic surgery. And observing breast surfaces from multiple views is needed in accurate breast volume measurement. On the other hand most 3D vision systems only recover 3D data from a single viewpoint and the recovered 3D data are often incomplete due to the occlusion problem and thus cannot uniquely define the surface. A unique and more complete description of the surface is necessary for most applications such as measuring area or volume and finding the best 3D registration between corresponding surfaces. This thesis describes a structured light based system for fast and noncontact 3D measurement of the human body from multiple views. A particular application of our system is the study of human lactation through measuring the breast surface and volume. Fast, accurate, non-contact, and biologically safe measurement is the key requirement in our application. We use structured light to fulfill the requirement. Based on the SHAPE system [4,3], a single view structured light system developed at Monash University, our system for breast volume measurement generates more complete 3D information on object surfaces by observing the object from more than one viewpoint. The breast volume is computed using the integrated data from all views. We present a simple method that performs 3D measurement from multiple views simultaneously. Combined with a camera and a projector, a mirror is used in the method to create an additional viewpoint to recover the occluded regions that are illuminated by the light source but were previously invisible to the camera. Images from the two views one directly seen by the camera and the other seen via the mirror are taken simultaneously. We develop the method for the purpose of achieving more complete measurements without increasing image capture time, which is very useful in situations where both speed and accuracy are important. The complete 3D description of the surface of objects requires the acquisition of several images from different vantage viewpoints. Each image contains information on the part of the object that is visible from its viewpoint. A very important task consists in the integration of the information present in each view. We have developed a two view system to achieve a more complete breast volume measurement. The system uses a stationary sensor at each view. Our system can largely eliminate the occlusion regions produced by a single view system and all data from different views are integrated into an object centered coordinate system and resampled by a single parametric grid. The system has been used to accurately measure short term changes in breast volume for lactating mothers. Currently, the system is also used to observe the breast volume change of pregnant women over many weeks' time.

"
Several factors play a role in stability of impressions made from elastomeric impression materials. These include
polymerization shrinkage, loss of by-products during condensation, thermal contraction from oral temperature to room temperature, imbibition when exposed to water, disinfectant or high humidity and incomplete recovery from deformation due to viscoelastic behavior. An ideal impression material should be dimensionally stable over time to allow for pour at the convenience of the operator. Several studies evaluated the dimensional accuracy of elastomeric impression materials based on various factors including effects of repeat pour, temperature, humidity, disinfectants, impression techniques, and filler loading amongst others. Most of the previous studies did not use the standardized method described by the ADA specification for elastomeric impression materials..."

Abstract:
This thesis introduces novel algorithms for 3D shape recovery under multiple viewpoints and single viewpoint. Surface of a 3D object is reconstructed by either graph-cuts using images under multiple viewpoints, depth from reflection under a fixed viewpoint, or depth from refraction under a fixed viewpoint. The first part of this thesis revisits the graph-cuts based approach for solving the multi-view stereo problem and proposes a novel foreground / background energy. Unlike traditional graph-cuts based methods which focus on the photo-consistency energy, this thesis targets at deriving a robust and unbiased foreground / background energy which depends on data. It is shown that by using the proposed foreground / background energy, it is possible to recover the object surface from noisy depth maps even in the absence of the photo-consistency energy, which demonstrates the effectiveness of the proposed energy. In the second part of this thesis, a novel method for shape recovery is proposed based on reflection of light using a spherical mirror. Unlike other existing methods which require the prior knowledge of the position and the radius of the spherical mirror, it is shown in this thesis that the object can be reconstructed up to an unknown scale using an unknown spherical mirror. This thesis finally considers recovering object surfaces based on refraction of light and presents a novel depth from refraction method. A scene is captured several times by a fixed camera, with the first image (referred to as the direct image) captured directly by the camera and the others (referred to as the refracted images) by placing a transparent medium with two parallel planar faces between the scene and the camera. With a known pose and refractive index of the medium, a depth map of the scene is then recovered from the displacements of scene points in the images. Unlike traditional depth from refraction methods which require extra steps to estimate the pose and the refractive index of the medium, this thesis presents a novel method to estimate them from the direct and refracted images of the scene. It is shown that the pose of the medium can be recovered from one direct image and one refracted image. It is also shown that the refractive index of the medium can be recovered with a third image captured with the medium placed in a different pose.

Abstract:
Breathing disorders can potentially influence craniofacial development through interactions between the respiratory flow and genetic and environmental factors. It has been suggested that certain medical conditions such as persistent rhinitis and renal insufficiency may have an influence on face shape. The effects of these conditions are likely to be subtle; otherwise they would appear as an obvious visible facial feature. The use of three-dimensional imaging provides the opportunity to acquire accurate and high resolution facial data to explore the influence of medical condition on facial morphology. Therefore, the aim of the present study is to investigate the influence of breathing disorders (asthma, atopy, allergic rhinitis and sleep disordered breathing) on face shape in children. The study sample, comprising of 4784 British Caucasian children of which 2922 (61.1%) were diagnosed with a breathing disorder, was selected from the Avon Longitudinal Study of Parents and Children (ALSPAC), which had been conducted to investigate the genetic and environmental determinants of development, health and disease. Three-dimensional surface laser scans were conducted on the children when they were 15 years old. A total of 21 reproducible facial landmarks (x, y, z co-ordinates) were identified. Average facial shells were constructed for each of the different disease groups and compared to facial shells of healthy asymptomatic children. Face-shape variables (angular and linear measurements) were analysed with respect to the different breathing disorders by employing a variety of statistical methods, including t-tests, chi-square tests, principal component analysis, binary logistic regression and analysis of variance (ANOVA). The results reveal that individual breathing disorders have varying influences on facial features, including increased anterior lower face height, a more retrognathic mandible and reduced nose width and prominence. The study also shows that the early removal of adenoids and tonsils can have a significant effect on obstructive breathing, resulting in the restoration of the facial morphology to its normal shape. This was particularly evident in children with normal BMIs. Surprisingly, no significant differences in face shape were detected in children with multiple diseases (combinations of asthma, allergic rhinitis, atopy and sleep-disordered breathing) when compared to healthy children. This may indicate the multifactorial, complex character of this spectrum of diseases. The findings provide evidence of small but potentially real associations between breathing disorders and face shape. This was largely attributable to the use of high-resolution and reproducible three-dimensional facial imaging alongside a large study sample. They also provide the scientific community with a detailed and effective methodology for static facial modelling that could have clinical relevance for early diagnosis of breathing disorders. Furthermore, this research has demonstrated that the ALSPAC patient archive offers a valuable resource to clinicians and the scientific community for investigating associations between various breathing disorders and face shape.

Abstract:
Bibliography: leaves 194-198.
The following dissertation considers the single-scan two-dimensional positional accuracy of a pulsed surveillance radar. The theoretical aspects to the positional accuracy are considered and a generalized analytical approach is presented. Practical position estimators are often complex, and theoretical predictions of their performance generally yield unfriendly mathematical equations. In order to evaluate the performance of these estimators, a simulation method is described based on replicating the received video signal. The accuracy of such a simulation is determined largely by the accuracy of the models applied, and these are considered in detail. Different azimuth estimation techniques are described, and their performances are evaluated with the aid of the signal simulation. The best azimuth accuracy performance is obtained with the class of analogue processing estimators, but they are found to be more susceptible to interference than their binary processing counterparts. The class of binary processing estimators offer easily implemented techniques which are relatively insensitive to radar cross-section scintillation characteristics. A hybrid estimator, using both analogue and binary processing, is also evaluated and found to give an improved accuracy performance over the binary processing method while still maintaining the relative insensitivity to radar cross-section fluctuation.

Abstract:
Textile structures made of biocompatible, osteoconductive and resorbable chitosan-filaments provide excellent preconditions as scaffolds for Bone Tissue Engineering applications. The novel Net Shape Nonwoven (NSN) technique that enables short fibers to be processed into three-dimensional net-shaped nonwoven structures with adjustable pore size distributions is described. NSN scaffolds made of pure chitosan fibers were fabricated. NSN hybrid scaffolds for improved initial cell adhesion were realized by combining the NSN technique with electrospinning and dip-coating with collagen, respectively. Scanning electron microscopy and liquid displacement porosimetry revealed an interconnecting open porous scaffold structure. The novel chitosan-hybrid scaffolds provide proper conditions for adhesion, proliferation and differentiation of the seeded human bone marrow stromal cells, proving that they are suitable for usage in hard-tissue regeneration.

Abstract:
En bioinformatique structurale, la prédiction de la (des) structure(s) secondaire(s) des acides ribonucléiques (ARNs) constitue une direction de recherche majeure pour comprendre les mécanismes cellulaires. Une approche classique pour la prédiction de la structure postule qu'à l'équilibre thermodynamique, l'ARN adopte plusieurs conformations, caractérisées par leur énergie libre, dans l’ensemble de Boltzmann. Les approches modernes privilégient donc une considération des conformations dominantes. Ces approches voient leur précision limitées par l'imprécision des modèles d'énergie et les restrictions topologiques pesant sur les espaces de conformations.Les données expérimentales peuvent être utilisées pour pallier aux lacunes des méthodes de prédiction. Différents protocoles permettent ainsi la révélation d'informations structurales partielles via une exposition à un réactif chimique/enzymatique, dont l'effet dépend, et est donc révélateur, de la (les) structure(s) adoptée(s). Les données de sondage mono-réactif sont utilisées pour valider et complémenter les modèles d’énergie libre, permettant ainsi d’améliorer la précision des prédictions. En pratique, cependant, les praticiens basent leur modélisation sur des données de sondage produites dans diverses conditions expérimentales, utilisant différents réactifs ou associées à une collection de séquences mutées. Une telle approche intégrative est répandue mais reste manuelle, onéreuse et subjective. Au cours de cette thèse, nous avons développé des méthodes in silico pour une modélisation automatisée de la structure à partir de plusieurs sources de données de sondage.En premier lieu, nous avons établi des pipelines d’analyse automatisés pour l'acquisition de profils de réactivité à partir de données brutes produites à travers une série de protocoles. Nous avons ensuite conçu et implémenté une nouvelle méthode qui permet l'intégration simultanée de plusieurs profils de sondage. Basée sur une combinaison d'échantillonnage de l'ensemble de Boltzmann et de clustering structurel, notre méthode produit des conformations dominantes, stables et compatible avec les données de sondage. En favorisant les structures récurrentes, notre méthode permet d’exploiter la complémentarité entre plusieurs données de sondage. Ses performances dans le cas mono-sondage sont comparables ou meilleures que celles des méthodes prédictives de pointe.Cette méthode a permis de proposer des modèles pour les régions structurées des virus. En collaboration avec des expérimentalistes, nous avons suggéré une structure raffinée de l'IRES du VIH-1 Gag, compatible avec les données de sondage chimiques et enzymatiques, qui nous a permis d’identifier des sites d'interactions putatifs avec le ribosome. Nous avons également modélisé la structure des régions non traduites d'Ebola. Cohérents avec les données de sondage SHAPE et les données de covariation, nos modèles montrent l’existence d'une tige-boucle conservée et stable à l'extrémité 5', une structure typiquement présente dans les génomes viraux pour protéger l'ARN de la dégradation par les nucléases.L’extension de notre méthode pour l’analyse simultanée de variants, appliquée dans un premier temps sur des mutants produits par le protocole Mutate-and-Map et sondés par le DMS, a permis d'enregistrer une amélioration en précision de prédiction. Pour éviter la production systématique de mutants ponctuels et exploiter le protocole récent SHAPEMap, nous avons conçu un protocole expérimental basé sur une mutagenèse non dirigé et le séquençage, où plusieurs ARN mutés sont produits et simultanément sondés. Nous avons traité l’affectation des reads aux mutants de références à l'aide d'une instance de l'algorithme "Expectation-Maximization" dont les résultats préliminaires, sur un échantillon de reads réduit/simulé, ont montré un faible taux d’erreurs d'assignation par rapport à une affectation classique des reads aux séquences d'ARN de référence
In structural bioinformatics, predicting the secondary structure(s) of ribonucleic acids (RNAs) represents a major direction of research to understand cellular mechanisms. A classic approach for structure postulates that, at the thermodynamic equilibrium, RNA adopts its various conformations according to a Boltzmann distribution based on its free energy. Modern approaches, therefore, favor the consideration of the dominant conformations. Such approaches are limited in accuracy due to the imprecision of the energy model and the structure topology restrictions.Experimental data can be used to circumvent the shortcomings of predictive computational methods. RNA probing encompasses a wide array of experimental protocols dedicated to revealing partial structural information through exposure to a chemical or enzymatic reagent, whose effect depends on, and thus reveals, features of its adopted structure(s). Accordingly, single-reagent probing data is used to supplement free-energy models within computational methods, leading to significant gains in prediction accuracy. In practice, however, structural biologists integrate probing data produced in various experimental conditions, using different reagents or over a collection of mutated sequences, to model RNA structure(s). This integrative approach remains manual, time-consuming and arguably subjective in its modeling principles. In this Ph.D., we contributed in silico methods for an automated modeling of RNA structure(s) from multiple sources of probing data.We have first established automated pipelines for the acquisition of reactivity profiles from primary data produced through a variety of protocols (SHAPE, DMS using Capillary Electrophoresis, SHAPE-Map/Ion Torrent). We have designed and implemented a new, versatile, method that simultaneously integrates multiple probing profiles. Based on a combination of Boltzmann sampling and structural clustering, it produces alternative stable conformations jointly supported by a set of probing experiments. As it favors recurrent structures, our method allows exploiting the complementarity of several probing assays. The quality of predictions produced using our method compared favorably against state-of-the-art computational predictive methods on single-probing assays.Our method was used to identify models for structured regions in RNA viruses. In collaboration with experimental partners, we suggested a refined structure of the HIV-1 Gag IRES, showing a good compatibility with chemical and enzymatic probing data. The predicted structure allowed us to build hypotheses on binding sites that are functionally relevant to the translation. We also proposed conserved structures in Ebola Untranslated regions, showing a high consistency with both SHAPE probing and evolutionary data. Our modeling allows us to detect conserved and stable stem-loop at the 5’end of each UTR, a typical structure found in viral genomes to protect the RNA from being degraded by nucleases.Our method was extended to the analysis of sequence variants. We analyzed a collection of DMS probed mutants, produced by the Mutate-and-Map protocol, leading to better structural models for the GIR1 lariat-capping ribozyme than from the sole wild-type sequence. To avoid systematic production of point-wise mutants, and exploit the recent SHAPEMap protocol, we designed an experimental protocol based on undirected mutagenesis and sequencing, where several mutated RNAs are produced and simultaneously probed. Produced reads must then be re-assigned to mutants to establish their reactivity profiles used later for structure modeling. The assignment problem was modeled as a likelihood maximization joint inference of mutational profiles and assignments, and solved using an instance of the "Expectation-Maximization" algorithm. Preliminary results on a reduced/simulated sample of reads showed a remarkable decrease of the reads assignment errors compared to a classic algorithm
