Abstract:
This document is a multiple-article format dissertation that discusses the iterative design, development, and evaluation processes necessary to create high quality learning analytics dashboard systems. With the growth of online and blended learning environments, the amount of data that researchers and practitioners collect from learning experiences has also grown. The field of learning analytics is concerned with using this data to improve teaching and learning. Many learning analytics systems focus on instructors or administrators, but these tools fail to involve students in the data-driven d

Abstract:
Auditory graphs and active point estimation provide an inexpensive, accessible alternative for low vision and blind K-12 students using number lines and coordinate graphs. In the first phase of this research program, a series of four psychophysics studies demonstrated an interactive auditory number line that enables blind, low vision, and sighted people to find small targets with a laptop, headphones, and a mouse or a keyboard. The Fitts' Law studies showed that, given appropriate auditory feedback, blind people can use a mouse. In addition, auditory feedback can generate target response patte

Abstract:
It has been shown that representing data with the right visualization increases the understanding of qualitative and quantitative information encoded in documents. However, current tools for generating such visualizations involve the use of traditional WIMP techniques, which perhaps makes free interaction and direct manipulation of the content harder. In this thesis, we present a pen-based prototype for data visualization using 10 different types of bar based charts. The prototype lets users sketch a chart and interact with the information once the drawing is identified. The prototype's user

This dissertation has two principal components: the dimension of posets with planar cover graphs, and the cartesian product of posets whose cover graphs have hamiltonian cycles that parse into symmetric chains. Posets of height two can have arbitrarily large dimension. In 1981, Kelly provided an infinite sequence of planar posets that shows that the dimension of planar posets can also be arbitrarily large. However, the height of the posets in this sequence increases with the dimension. In 2009, Felsner, Li, and Trotter conjectured that for each integer h at least 2, there exists a least po

Abstract:
The use of the continuous phase modulation (CPM) is interesting when the channel represents a strong non-linearity and in the case of limited spectral support; particularly for the uplink, where the satellite holds an amplifier per carrier, and for downlinks where the terminal equipment works very close to the saturation region. Numerous studies have been conducted on this issue but the proposed solutions use iterative CPM demodulation/decoding concatenated with convolutional or block error correcting codes. The use of LDPC codes has not yet been introduced. Particularly, no works, to our know

Abstract:
Optimal input design concerns the design of an input sequence to maximize the information retrieved from an experiment. The design of the input sequence is performed by optimizing a cost function related to the intended model application. Several approaches to input design have been proposed, with results mainly on linear models. Under the linear assumption of the model structure, the input design problem can be solved in the frequency domain, where the corresponding spectrum is optimized subject to power constraints. However, the optimization of the input spectrum using frequency domain techn

Cette thèse propose des modèles et des méthodes pour étudier le contrôle du risque dans de larges systèmes financiers. Nous proposons dans une première partie une approche structurelle : nous considérons un système financier représenté comme un réseau d’institutions connectées entre elles par des interactions stratégiques sources de financement mais également par des interactions qui les exposent à un risque de contagion de défaut. La nouveauté de notre approche réside dans le fait que ces deux types d’interaction interfèrent. Nous proposons des nouvelles notions d’équilibre pour ces systèmes

Abstract:
Dans de nombreuses applications industrielles les matériaux polycristallins sont soumis à de hautes températures, auxquelles le mécanisme de glissement aux joints de grains (GBS pour grain boundary sliding) tient un rôle essentiel. Il est fortement couplé à la plasticité intra cristalline, cependant peu de modèles tiennent compte de ce couplage. Le GBS est encore un mécanisme mal compris pour lequel nous manquons de quantifications expérimentales. Nous avons développé à cette fin un dispositif pour réaliser des expériences de compression in-situ dans un microscope électronique à balayage, équi

Abstract:
Master´s thesis focuses on the utilisation of project management methodology within the design of a project in a selected company. It specifies theoretical sources which are the key for the project plan proposal. It applies the theory to the project of introducing electronic commerce in the field of building material sale. The thesis containts the plan proposal and optimisation of the project in terms of time, costs and use of available resources, together with the analysis of a company environment.

Abstract:
In this work, we demonstrate the bottom-up on-surface synthesis of poly(para-dibenzo[bc,kl]-coronenylene) (PPDBC), a zigzag edge-encased analog of poly(para-phenylene) (PPP), and its lateral fusion into zigzag edge-extended graphene nanoribbons (zeeGNRs). Toward this end, we designed a dihalogenated di(meta-xylyl)anthracene monomer displaying strategic methyl groups at the substituted phenyl ring and investigated its applicability as precursor in the thermally induced surface-assisted polymerization and cyclodehydrogenation. The structure of the resulting zigzag edge-rich (70%) polymer PPDBC w

Mestrado em Economia Internacional e Estudos Europeus<br>As Cadeias Globais de Valor (CVG) representam a fragmentação da produção em várias fases, cada uma localizada num país diferente. Neste contexto, as estatísticas tradicionais de comércio não refletem a fragmentaão da produção internacional, sendo responsáveis pela dupla-contagem nos dados de importações e exportações. Para preencher esta lacuna, surgiram bases de dados Input-Output com links internacionais. Vários economistas internacionais e econofísicos defendem o potencial da análise de redes para a análise e visualização de redes de

Abstract:
Na primeira parte deste trabalho estudamos a convergência para a distribuição de equilíbrio em grafos não autónomos periódicos. Introduzimos a noção de equilíbrio em grafos não autónomos e apresentamos uma estimativa superior para a distância ao equilíbrio, `a custa do segundo valor próprio em módulo das matrizes produto, supondo todas as matrizes erg´odicas e pelo menos uma delas reversível. A estimativa obtida depende explicitamente da dimensão das matrizes consideradas. Estabelecemos a relação entre grafos autónomos e cadeias de Markov não homogéneas.
