As the economic opportunities fostered by large cities become more diverse, the travel patterns of public transport users become more heterogeneous. From personalized customer information, to improved travel demand models, understanding these heterogeneous travel patterns is useful for a number of applications relevant to public transport agencies. This thesis explores how smart card data can be used to analyze and compare the structure of individual travel patterns observed over several weeks. Specifically, the way in which multiple journeys and activities are ordered and combined into repeated patterns, both by the same individual over time and across individuals is evaluated from the journey sequence of each user. The research is structured around three objectives. First, we introduce a representation of individual travel patterns and develop a measure of travel sequence regularity. The mobility of each individual is modeled as a stochastic process with memory, of which each new realization represents an activity or journey. Entropy rate, a measure of randomness in the stochastic process, is used to quantify repetition in the order of journeys and activities. This analysis reveals that the order of events is an important component of regularity not explicitly captured in previous literature. Second, we develop an approach to identify clusters of travel patterns with similar structure considered with respect to public transport usage and activity patterns. Finally, we present an exploratory evaluation of the associations between the identified clusters and socio-demographic characteristics by linking smart card data to an annual travel diary survey. These three objectives are considered in the context of a practical application using the transactions of a sample of approximately 100,000 users collected between February 10th and March 10th 2015 in London.

Повний текст джерелаCross Laminated Timber (CLT, or crosslam) panels are engineered timber products composed of layers made of wooden lamellas placed side by side, glued on their upperand lower faces and stacked crosswise. In the present thesis, the influence of lateral spaces between lamellas of each layer on the panel’s mechanical response is investigated with modeling and tests. Both configurations of standard panels having short spaces and innovative CLT panels with large spaces are analyzed.As a first approach, the bending behavior of standard crosslam was modeled by means of an equivalent-layer model based on simplified hypotheses on mechanical properties of laterally glued or unglued layers. The good agreement of the predicted behavior with an experiment of the literature finally allowed an investigation on several CLT properties by means of parameter studies.Then, 4-points bending tests on standard and innovative CLT floors were performed in order to quantify the influence of periodic spaces on the panels' mechanical response. It appears that the influence of transverse shear effects on the elastic and failure behavior of spaced CLT increases with the increasing spaces between boards.In order to take into account transverse shear effects, spaced CLT have been modeled as periodic thick plates by means of a higher-order plate theory for laminated plates. This model has been applied to the geometry of spaced CLT with a periodic homogenization scheme. Existing simplified methods for spaced crosslam were compared as well with refined modeling and test results. Moreover, available in-plane shear tests of the literature have been compared to the modeling results. It appears that the bending behavior of spaced CLT can be predicted with simplified existing approaches, while only the more refined modeling can predict the in-plane and transverse shear behavior. Then, closed-form solutions for predicting spaced CLT elastic behavior were derived in order to encourage the application of spaced CLT panels in modern timber construction.One further study within this thesis concerns the analysis of fire-exposed standard CLT floors. The comparison between test results and both advanced and simplified modeling led to a suggestion for a possible improvement the standard fire design model

Повний текст джерелаThe general theory of relativity describes the effect of gravitation in terms of the geometry of spacetimes. The curvature of Lorentzian manifolds is related to the energy and momentum of matter (or vacuum) by the Einstein equations, a system of nonlinear partial differential equations. In the 1950s the initial value formulation and local existence of solutions to the Einstein equations were established. As of yet the global structure of spacetimes is much less understood. Motivated by this I investigate the evolution as well as the regularity of spacetimes. I show that certain energy estimates can be controlled by one-sided bounds on the geometry only. Estimates of the Bel-Robinson energy, for example, play a crucial role in the derivation of breakdown criteria for solutions of the vacuum Einstein equations. As an important astrophysical model spacetimes with perfect fluid sources are considered. An existence theory for spherically symmetric solutions to the Einstein-Euler equations is presented, and, above all, I identify for the first time a class of untrapped initial data that leads to the dynamical formation of trapped surfaces. To allow for shock waves, solutions are regarded to be of bounded variation. The distributional framework is essential here and in other areas of general relativity, and it is crucial to understand if and how the regularity of metrics influences the geometry of spacetimes. I account for this by deriving some general results on continuous Riemannian metrics and algebras of generalized functions. This thesis thus illustrates that spacetimes of low regularity exhibit a wide range of interesting phenomena during their evolution

Повний текст джерелаIn this thesis we develop a general theory to prove the existence of several Itô formulae on the one dimensional stochastic heat equation driven by additive space-time white noise. That is denoting by u the solution of this SPDE for any smooth enough function f we define some new notions of stochastic integrals defined upon u, which cannot be defined classically, in order to deduce new identities involving f(u) and some non trivial corrections. These new relations are obtained by using the theory of regularity structures and the theory of rough paths. In the first chapter we obtain a differential and an integral identity involving the reconstruction of some modelled distributions. Then we discuss a general change of variable formula over any Hölder continuous path in the context of rough paths, relating it to the notion of quasi-shuffle algebras and the family of so called quasi-geometric rough paths. Finally we apply the general results on quasi-geometric rough paths to the time evolution of u. Using the Gaussian behaviour of the process u, most of the terms involved in these equations are also identified with some classical constructions of stochastic calculus

Повний текст джерелаThis thesis is a contribution to the fine tubular structures detection problem in a 2-D or 3-D image. We arespecifically interested in the case of angiographic images. The vessels are surrounded by noise and thenthe question is to segment precisely the blood network. The theoretical framework of our work is thecalculus of variations and we focus on the Mumford-Shah energy. Initially, this model is adapted to thedetection of volumetric structures extended in all directions of the image. The aim of this study is to buildan energy that favors sets which are extended in one direction, which is the case of fine tubes. Then, weintroduce a new unknown, a Riemannian metric, which captures the geometric structure at each point ofthe image and we give a new formulation of the Mumford-Shah energy adapted to this metric. Thecomplete analysis of this model is done: we prove that the associated problem of minimization is wellposed and we introduce an approximation by gamma-convergence more suitable for numerics. Eventually,we propose numerical experimentations adapted to this approximation

Повний текст джерелаWe develop new techniques in the setting of FS and DFS spaces (Fréchet-Schwartz spaces and their strong duals) and apply them to the study of the following question: when regularity properties of a general linear differential operator (between Gevrey vector bundles over a Gevrey manifold) imply solvability of its transpose in the sense of ultradistributions? This question is studied for a class of abstract operators that encompasses the usual partial differential operators with Gevrey coefficients, but also some flavors of pseudodifferential operators on compact manifolds and some classes of operators with infinite order. In this setting, we obtain a new proof of a global result on compact manifolds (global Gevrey hypoellipticity of the operator implying global solvability of the transpose), as well as some results in the non-compact case by means of the so-called property of non-confinement of singularities. We then move to some concrete applications, especially for Hörmander operators, operators of constant strength and locally integrable systems of vector fields. We also analyze some instances of a conjecture stated in a recent paper of F. Malaspina and F. Nicola (2014), which asserts that, in differential complexes naturally arising from locally integrable structures, local solvability in the sense of ultradistributions (near a point, in some fixed degree) implies local solvability in the sense of distributions. We establish the validity of the conjecture when the cotangent structure bundle is spanned by the differential of a single first integral.

Повний текст джерелаThis thesis is concerned with the study of singular stochastic partial differential equations (SPDEs). We develop extensions to existing solution theories, present fundamental interconnections between different approaches and give applications in financial mathematics and mathematical physics. The theory of paracontrolled distribution is formulated for discrete systems, which allows us to prove a weak universality result for the parabolic Anderson model. This thesis further shows a fundamental relation between Hairer's modelled distributions and paraproducts: The space of modelled distributions can be characterized completely by using paraproducts. This can be seen a generalization of the Fourier description of Hölder spaces. Finally, we prove the existence of solutions to the stochastic Schrödinger equation on the full space and provide an application of Hairer's theory to option pricing.

The author explores protein secondary structure regularity from the perspective of sequences. Regularity is defined in terms of a schema discovered by a cluster-based genetic algorithm. Two steps taken to validate the algorithm were a) finding the weightiness of cluster and b) comparing the approach with data mining methods. Schemata were used to address secondary structure predictions for residues that PSIPRED and PROF could not predict. The results indicate that the proposed schemata can improve prediction accuracy for these residues by approximately 40% and 60% for the CB513 and RS126 data sets, respectively. Furthermore, schemata combine the prediction results of PSIPRED and PROF to improve secondary structure prediction. A bioinformatics teaching plan using a problem-based approach is discussed.

The objectives of this research were two: First, to explore and discuss the synthesized particle diameters by altering reaction temperature condition and reaction time in the preparation of silica microspheres by sol-gel method. Second, we used gravitational sedimentation method, i.e. a bottom-up self-assembly, to obtain regularly arrayed colloidal crystal structure using mono sized SiO2 spherical particles. 1. The preparation of submicron monodispersive silica microspheres by sol-gel method: The synthesis started from tetra-ethyl orthosilicate (TEOS) as precursor, ethanol as reaction solvent, and ammonia solution as catalyst, and processed in basic-catalyzed aqueous medium. After hydrolysis, condensation, cross-linking and gelation reactions, submicron silica microspheres were formed. The synthesis reaction temperature ranged from 0oC~75oC and the reaction time was 2 hours. The particle diameter of the synthesized spheres were analyzed by the particle-size analyser. Experimental results indicated that the size of the synthesized silica microspheres varied from 0.443 mm to 0.625 mm. As the reaction time was increased the diameter of silica microspheres increased (from 0.473 to 0.625mm). As the reaction temperature was increased the diameter of silica microspheres was fond to decrease accordingly (from 0.625 to 0.443mm). 2. Use of mono-sized SiO2 particles for self-assembly of regularly arrayed, colloidal crystal structure: In this work, we used gravitational sedimentation method to assemble SiO2 particles on Si wafer template epitaxially to grow regularly crystal-like structure, and to use the field emission scanning electron microscope (FE-SEM) to observe the packing structure. Experimental results indicated that in different volume fraction (0.5 vol.%~3 vol.%) and sedimentation temperature range (50oC and 100oC, respectively), as the solids fraction was held at 3 vol.% and the sedimentation temperature was 50oC, a larger area (about 250 ´ 250 mm2) of regularly arrayed, colloidal crystal structure was resulted.
