Résumé :

The aim of this PhD thesis is to study the area functional for submanifolds immersed in an equiregular graded manifold. This setting, extends the sub-Riemannian one, removing the bracket generating condition. However, even in the sub-Riemannian setting only sub-manifolds of dimension or codimension one have been extensively studied. We will study the general case and observe that in higher codimension new phenomena arise, which can not show up in the Riemannian case. In particular, we will prove the existence of isolated surfaces, which do not admit degree preserving variation: a phenomena observed by now only for curves, related to the notion of abnormal geodesics.

Résumé :

We introduce and study submanifold bridge processes. Our method involves proving a general formula for the integral over a submanifold of the minimal heat kernel on a complete Riemannian manifold. Our formula expresses this object in terms of a stochastic process whose trajectories terminate on the submanifold at a fixed positive time. We study this process and use the formula to derive lower bounds, an asymptotic relation and derivative estimates. Using these results we introduce and characterize Brownian bridges to submanifolds. Before doing so we prove necessary estimates on the Laplacian of the distance function and define a notion of local time on a hypersurface. These preliminary developments also lead to a study of the distance between Brownian motion and a submanifold, in which we prove exponential bounds and concentration inequalities. This work is motivated by the desire to extend the analysis of path and loop space to measures on paths which terminate on a submanifold.

Résumé :

This thesis concerns the relationship of submanifold geometry, in both the smooth and discrete sense, to representation theory and the theory of integrable systems. We obtain Lie theoretic generalisations of the transformation theory of projectively and Lie applicable surfaces, and M�obius-flat submanifolds of the conformal n-sphere. In the former case, we propose a discretisation. We develop a projective approach to centro-ane hypersurfaces, analogous to the conformal approach to submanifolds in spaceforms. This yields a characterisation of centro-ane hypersurfaces amongst M�obius-flat projective hypersurfaces using polynomial conserved quantities. We also propose a discretisation of curved flats in symmetric spaces. After developing the transformation theory for this, we see how Darboux pairs of discrete isothermicnets arise as discrete curved flats in the symmetric space of opposite point pairs. We show how discrete curves in the 2-sphere fit into this framework.

Résumé :

Synthetic or qualitative methods can provide insight into geometric structures not apparent from the purely analytic point of view. For example, much of the geometry of a classical surface in Euclidean space is coded in the differential topology of its family of normal lines. This thesis extends the range of applicability of such methods by developing the basic theory of submanifold families in general, emphasizing higher-order contact phenomena and making use of the modern theory of jets. A main technical contribution is, in certain cases, the calculation of invariants of parameterized submanifold jets by the reparameterization group, a construction of the quotient varieties, and compactifications of these varieties.

As applications, in 2 dimensions we deduce: - a description of projective structures by (second order) tensorial data, - a characterization of the curve families realizable by geodesics for some connection, and a description of the connections in this case, and - a linearizability criterion for curve families, including d-webs for d > 3, and in higher dimensions: - general formulas for envelopes of submanifold families, including line envelopes for visual applications, and - a characterization of the extrinsic geometry of m-submanifolds in projective space RPⁿ, for certain m, including a generalization of the classical Wilczynski equations for surfaces in RP³.

Résumé :

In this thesis an algebraic structure, called real calculus, is used as a way to represent noncommutative manifolds in an algebraic setting. Several classical geometric concepts are defined for real calculi, such as metrics and affine connections, and real calculus homomorphisms are introduced. These homomorphisms are then used to define embeddings of real calculi representing manifolds, anda notion of minimal embedding is introduced. The motivating example of the thesis is the noncommutative torus as embedded into a localization of the noncommutative 3-sphere, where it is shown that the noncommutative torus is a minimal embedding of the noncommutative 3-sphere for certain perturbations of the standard metric.

Résumé :

Motivated by the desire to understand classical-quantum correspondences, we study concentration phenomena of approximate eigenfunctions of a semiclassical pseudodifferential operator $P(h)$. Such eigenfunctions appear as steady state solutions of quantum systems. Here we think of $h$ as being a small parameter such that $h^{2}$ is inversely proportional to the energy of such a system. As we understand classical mechanics to be the high energy (or small $h$) limit of quantum mechanics we expect the behaviour of eigenfunctions $u(h)$ for small $h$ to be related to properties of the associated classical system. In particular we study the connection between the classical flow and the quantum concentration properties. The flow, $(x(t),\xi(t))$, of a classical system describes the system's motion through phase space where $x(t)$ is interpreted as position and $\xi(t)$ is interpreted as momentum. In the quantum regime we think of an eigenfunction as being composed of highly localised packets moving along bicharacteristics of the classical flow. With this intuition we relate concentration of eigenfunctions in a region to the time spent by projections of bicharacteristics there. We use the $L^{p}$ norm of $u$ when restricted to submanifolds as a measure of concentration. A high $L^{p}$ norm particularly for small $p$ is indicative of concentration near the submanifold. We reduce the estimates on eigenfunctions to operator norm estimates on associated evolution operators. Using the semiclassical analysis methods developed in Chapter 3 we express these evolution operators as oscillatory integral operators. Chapter 2 covers the technical background needed to work with such operators. In Chapter 4 we determine eigenfunction estimates for eigenfunctions restricted to a smooth embedded submanifold $Y$ of arbitrary dimension. If $Y$ is a hypersurface, the greatest concentration occurs when there are bicharacteristics of the classical flow embedded in $Y$. In Chapter 5 we assume that projections of such bicharacteristics can be at worst simply tangent to $Y$ and thereby obtain better results for small values of $p$.

Smith, Jack Edward. « Symmetry in monotone Lagrangian Floer theory ». Thesis, University of Cambridge, 2017. https://www.repository.cam.ac.uk/handle/1810/267745.

Texte intégral

Résumé :

In this thesis we study the self-Floer theory of a monotone Lagrangian submanifold $L$ of a closed symplectic manifold $X$ in the presence of various kinds of symmetry. First we consider the group $\mathrm{Symp}(X, L)$ of symplectomorphisms of $X$ preserving $L$ setwise, and extend its action on the Oh spectral sequence to coefficients of arbitrary characteristic, working over an enriched Novikov ring. This imposes constraints on the differentials in the spectral sequence which force them to vanish in certain situations. We then specialise to the case where $L$ is $K$-homogeneous for a compact Lie group $K$, meaning roughly that $X$ is Kaehler, $K$ acts on $X$ by holomorphic automorphisms, and $L$ is a Lagrangian orbit. By studying holomorphic discs with boundary on $L$ we compute the image of low codimension $K$-invariant subvarieties of $X$ under the length zero closed-open string map. This places restrictions on the self-Floer cohomology of $L$ which generalise and refine the Auroux-Kontsevich-Seidel criterion. These often result in the need to work over fields of specific positive characteristics in order to obtain non-zero cohomology. The disc analysis is then developed further, with the introduction of the notion of poles and a reflection mechanism for completing holomorphic discs into spheres. This theory is applied to two main families of examples. The first is the collection of four Platonic Lagrangians in quasihomogeneous threefolds of $\mathrm{SL}(2, \mathbb{C})$, starting with the Chiang Lagrangian in $\mathbb{CP}^3$. These were previously studied by Evans and Lekili, who computed the self-Floer cohomology of the latter. We simplify their argument, which is based on an explicit construction of the Biran-Cornea pearl complex, and deal with the remaining three cases. The second is a family of $\mathrm{PSU}(n)$-homogeneous Lagrangians in products of projective spaces. Here the presence of both discrete and continuous symmetries leads to some unusual properties: in particular we obtain non-displaceable monotone Lagrangians which are narrow in a strong sense. We also discuss related examples including applications of Perutz's symplectic Gysin sequence and quilt functors. The thesis concludes with a discussion of directions for further research and a collection of technical appendices.

Résumé :

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Linguistics and Philosophy, 2002.
Includes bibliographical references (leaves 190-196).
In this project we examine the DP-internal behavior of degree operators contained in attributive extended APs, specifically degree fronting (so sunny a day) and degree right extraposition (a day sunny enough). We argue that both processes have to do with the scope of the degree operator, namely, that degree fronting is a diagnostic of clausal scope of the degree operator, while right extraposition is overt QR to the DP-internal landing site where a quantifier can be interpreted. We first show that pre-determiner APs in Germanic languages (so sunny a day) are moved to [Spec, NumP] only if they contain a degree operator, i.e. an element that cannot be interpreted in situ. We will then show that the appearance of the adjectival projection in that position is due to pied-piping, and that different degree operators behave differently with respect to how much material is moved overtly (pied-piping). We then turn to right extraposition. We will show that it can be differentiated from other cases traditionally denoted by the same term (e.g. a professor proud of her children). On the other hand, it has certain properties permitting to assimilate it to DP-extraposition to the right periphery of the vP (Heavy NP Shift) - it has new information status and permits stranding of the argument of the degree operator (a more interesting problem than this). These and similar factors suggest that right extraposition of degree-containing extended APs is overt QR of the degree operator accompanied by more or less pied-piping. The overall picture seems to be that QR an overt movement processes examined for clausal projections exist in nominal projections as well and have similar properties.

Résumé :

ABSTRACT Although nanotechnology may potentially contribute to sustainable innovation, there are concerns that certain nanomaterials may pose novel risks for the human health and the environment (Allianz et al 2009). It has been recognized that substantial uncertainties constrain the conventional risk assessment (RA) of chemicals when applied to ENMs, which raises health and safety concerns. (Hristozov et al 2012). Engineered nanomaterials (ENMs) have different properties compared to their bulk counterparts, which enables unique applications, but may lead to novel mechanism of toxicity. Since it appeared that no clear and universally accepted definition of a nanomaterial is present, and that a relevant measure for expressing hazard and exposure is as yet not known.(Pronk et al. 2009), therefore a need for more scientific knowledge and firm government regulations. In addition to insufficiency of the standard information requirements to assess hazard and exposure, and other data gaps, it cannot be determined to what extent the nano-form of a substance corresponds to the bulk form of the same substance. To this end, a life cycle perspective is considered towards the analysis of nano specific fate, transport, toxicity and impacts of ENM on humans and environments. Presently, research institutes, regional and national governments and international organization are working on an integrated top-down strategy to guide bottom-up research activities on the state-of-the-art of the regulation of nanomanufacturing. This thesis examines the suitability of the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation for safe use of Nanomaterials. The process critically review the state of the art in the area of nanosafety assessment with a case study of use of nano-silver. Coupled with a data gap analysis and comparative review of emerging methods and tools, the Analytical Hierarchy process in SWOT analysis of the current applicable ecological and occupational tools is used to analyse the strengths, weaknesses, opportunities and threats related to available methods and tools. This review will be used as the basis for developing a strategy for integrated risk assessment for nano-silver. These activities will contribute to (1) the proposal of a framework for integrated (human health and ecological) risk assessment of ENM, tailored to the current REACH regulations, (2) formulation of a roadmap for sustainable nanomanufacturing. Chapter one deals with the process of human health and ecological risk assessment. Different stages of risk assessment, requirements for risk evaluation and available methodologies are described. Chapter two reviews the existing tools for (ecological and occupational assessment), using Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis. Ranking of the tools are useful to derive quantitative information and their versatility for present and anticipated applications. Chapter three presents two case studies of nano-silver containing products: HeiQAGS-20(textile material) and Biocides (agricultural chemical) , performed by regulatory bodies US Environmental protection agency (EPA) and European Chemical Agency (ECHA). respectively. Dealing with different processes that describe the preparation, forms of nanomaterials attributes and their chemical reactivity that lead to the Environmental fate and transport. Chapter four discusses limitations, uncertainties and possible solutions at different stages of risk assessment process and proposes a new framework for sustainable manufacturing Chapter five presents a roadmap towards a decision making process for sustainable nanomanufacturing using the analysis of risk assessment.

Résumé :

There are many issues that relate to the efficacy of the undergraduate degree in the field of communicative disorders. Some have advocated for the elimination of the degree while others vigorously fight to maintain it. Some believe that there should be clinic associated with the undergraduate degree while others argue to have the degree but without clinic. Some state departments of education allow persons with an undergraduate degree in communicative disorders to practice in the schools, others do not. Colleges and universities are afraid that without an undergraduate degree program, their departments will be seen as vulnerable to elimination in the academy. Other colleges and universities want to close their undergraduate programs to concentrate on their master's and doctoral degrees, especially because of the shortage of doctoral level faculty to adequately staff all their programs. All of these issues and many more play into the debate about the continuation of the undergraduate degree in the field of communicative disorders. Today you are going to hear from three members of the Council who have very different viewpoints on the issue. We hope to stimulate discussion that will be productive in helping you and your departments determine the efficacy of your undergraduate degree in the field

Résumé :

We show that amongst all trees with a given degree sequence it is a ball where the vertex degrees decrease with increasing distance from its center that maximizes the spectral radius of the graph (i.e., its adjacency matrix). The resulting Perron vector is decreasing on every path starting from the center of this ball. This result it also connected to Faber-Krahn like theorems for Dirichlet matrices on trees. The above result is extended to connected graphs with given degree sequence. Here we give a necessary condition for a graph that has greatest maximum eigenvalue. Moreover, we show that the greatest maximum eigenvalue is monotone on degree sequences with respect to majorization. (author's abstract).

Résumé :

Industrial robotics concentrates on developing automated alternatives to human function. Most of the equipment is controlled by means of joystick. Through a joystick input, a robotic arm can be guided through the trajectories to accomplish complex manipulation tasks for its user. Nevertheless, conventional joysticks are mainly two dimensional input devices such as mouse or joystick with additional buttons. Hence it is necessary to design and build a more intuitive and user-friendly joystick model. This thesis aims at designing and building a six degree of freedom (DOF) joystick. Different designs are reviewed in the beginning of the thesis, the final prototype is proposed by refining the different designs. Structural analysis of the model is performed and verified using finite element software ANSYS and PATRAN. The prototype is tested to model the movement of the wire strips when various forces are applied. Preliminary test results are obtained and explained.

Texte intégral

Résumé :

This research explores the learning experiences of three mature students studying for a Foundation Degree – a two-year qualification, introduced in England and Wales in 2001, that uniquely spans the academic-vocational nexus within higher education. Data collected through interviews and journal entries were used to construct accounts of each of the students’ learning experiences, forming a longitudinal case study that spanned two years. This material is used in three ways to give insight into learning through a Foundation Degree. Firstly, the accounts stand by themselves as detailed descriptions of what it is like to learn through a Foundation Degree. Secondly, the accounts illustrate ways in which particular learning theories and models are helpful to understanding the students’ learning experiences, and also the areas in which some theories and models fall short. Thirdly, a new conceptual model has been developed which identifies six factors that significantly impact upon the Foundation Degree learner’s experience. Each of these factors has the potential to influence learning positively or negatively, depending on where it lies upon a continuum that polarises learning inhibitors and enablers. This model is used to scrutinise Foundation Degree teaching and learning practice, using the accounts as reference points, and more effective approaches to Foundation Degree delivery have been suggested.

Texte intégral

Résumé :

For a graph G = (V,E), we consider a bipartition {V1,V2} of the vertex set V by placing constraints on the vertices as follows. For every vertex v in Vi, we place a constraint on the number of neighbors v has in Vi and a constraint on the number of neighbors it has in V3-i. Using three values, namely 0 (no neighbors are allowed), 1 (at least one neighbor is required), and X (any number of neighbors are allowed) for each of the four constraints, results in 27 distinct types of bipartitions. The goal is to characterize graphs having each of these 27 types. We give characterizations for 21 out of the 27. Three other characterizations appear in the literature. The remaining three prove to be quite difficult. For these, we develop properties and give characterization of special families.

This research attempts to answer the question of why some attorneys obtain a second advanced degree after their law degree. That is, if a law degree is all that is needed to practice law, then why do some attorneys continue with their studies, especially since they lack an economic incentive to do so? The research includes a literature review with background information on credentialism and human capital theory, on lawyers and law school, dissatisfaction, income and debt, alternatives to law, joint graduate degree programs, and gender. SPSS modeling is utilized to arrive at the conclusion that human capital theory and satisfaction account for lawyers' attainment of additional degrees.

Résumé :

"The topology of a network (such as a telecommunications, multiprocessor, or local area network, to name just a few) is usually modelled by a graph in which vertices represent 'nodes' (stations or processors) while undirected or directed edges stand for 'links' or other types of connections, physical or virtual. A cycle that contains every vertex of a graph is called a hamiltonian cycle and a graph which contains a hamiltonian cycle is called a hamiltonian graph. The problem of the existence of a hamiltonian cycle is closely related to the well known problem of a travelling salesman. These problems are NP-complete and NP-hard, respectively. While some necessary and sufficient conditions are known, to date, no practical characterization of hamiltonian graphs has been found. There are several ways to generalize the notion of a hamiltonian cycle. In this thesis we make original contributions in two of them, namely k-walks and r-trestles." --Abstract.

Résumé :

This quantitative study examined the STEM degree aspirations of Latina/o students. Harper's (2010) Anti-Deficit Achievement framework on students of color in STEM was utilized to frame this study. Secondary data from the Cooperative Institutional Research Program's (CIRP), Freshman and Your First Year in College surveys were used to complete T-tests, correlations, and hierarchical regression analyses to explore gender differences in STEM degree aspirants and habits of mind among Latinas/os. Findings include probable major in STEM, faculty interaction, highest degree planned, academic self-concept and the habits of the mind CIRP construct were significant predictors of degree aspirations. Habits of the mind at the end of the first year in college were predicted by academic disengagement, positive cross-racial interactions, academic self-concept, and college involvement. Implications for STEM policy, student affairs practice and future research are discussed.

Résumé :

In this thesis, some characterizations of continua of finite degree are given. It turns out that being of finite degree (by formal definition) can be described by saying there exists an equivalent metric in which Hausdorff linear measure of the continuum is finite. I discuss this result in detail.

Résumé :

Thesis: Ph. D. in Linguistics, Massachusetts Institute of Technology, Department of Linguistics and Philosophy, 2019
Cataloged from PDF version of thesis.
Includes bibliographical references (pages 183-188).
This thesis investigates the morphosyntax and the semantics of comparatives and related degree constructions through the prism of a phenomenon called evaluativity, a type of inference whereby gradable adjectives receive a context-dependent interpretation. Pursuing the view that evaluativity is contributed by an optional null operator (EVAL, Rett 2008), this dissertation achieves the following results. First, it integrates a compositional analysis of evaluativity within a non-lexical view of antonymy. Second, it argues that the observed restrictions on the distribution of these inferences follow from independently motivated conditions that regulate the presence of the EVAL operator at the interfaces. In particular, three interface conditions are identified and discussed in detail: ++ At Logical Form (LF), derivations are subject to a structural economy condition, Minimize APs!, which executes transderivational comparisons over semantically equivalent Adjectival Phrases (APs).
The inclusion of EVAL in a parse licenses derivations that would otherwise be deemed deviant by this economy condition. ++ At Phonological Form (PF), the EVAL morpheme morphophonologically interacts with its surrounding environment. Specifically, EVAL is claimed to be a zero-morpheme subject to Myers Generalization, a PF-filter on syntactic derivations which prevents further morphological operations from applying to a zeroderived form. A consequence of this claim is that EVAL is licensed in derivations only where it does not disrupt post-syntactic operations that apply within the AP. ++ The distribution of EVAL is conditioned by aspects of Information Structure. In particular, in degree constructions that license contrastive adjectives, the distribution of focus is governed by (AvoIDF) which, in turn, interacts with conditions on deletion. Ultimately, the presence of EVAL can license a surface form which would otherwise get eliminated by PF-deletion.
In essence, the grammatical account of evaluativity developed in this thesis offers a window into the word-internal structure of complex degree expressions and presents new insights into the semantic and morphosyntactic primitives of the degree domain.
