Resumen
In this dissertation, we study models for coupled active--passive pedestrian dynamics from mathematical analysis and simulation perspectives. The general aim is to contribute to a better understanding of complex pedestrian flows. This work comes in three main parts, in which we adopt distinct perspectives and conceptually different tools from lattice gas models, partial differential equations, and stochastic differential equations, respectively. In part one, we introduce two lattice models for active--passive pedestrian dynamics. In a first model, using descriptions based on the simple

Resumen
With the growing amount of data generated in large heterogeneous repositories (such as the Word Wide Web, corporate repositories, citation databases), there is an increased need for the end users to locate relevant information efficiently. Text Classification (TC) techniques provide automated means for classifying fragments of text (phrases, paragraphs or documents) into predefined semantic types, allowing an efficient way for organising and analysing such large document collections. Current approaches to TC rely on supervised learning, which perform well on the domains on which the TC system

Resumen
A SEMantic Integration System (SemIS) allows a query over one database to be answered using the knowledge managed in multiple databases in the system. It does so by translating a query across the collaborative databases in which data is autonomously managed in heterogeneous schemas. In this thesis, we investigate the challenges that arise in enabling domain heterogeneous (DH) databases to collaborate in a SemIS. In such a setting, distributed databases modeled as independent data sources are pairwise mapped to form the semantic overlay network (SON) of the SemIS. We study two problems we belie

Beyond Central Processing Units (CPUs), different architectures such as massively parallel Graphics Processing Units (GPUs) and reconfigurable Field Programmable Gate Arrays (FPGAs) are seeing widespread adoption.

These predictors have been shown by Tartakovsky and Neuman (1998) to satisfy exactly a space-time nonlocal (integro-differential) conditional mean flow equat

Resumen
The security of a steganography system is defined by our ability to detect it. It is of no surprise then that steganography and steganalysis both depend heavily on the accuracy and robustness of our detectors. This is especially true when real-world data is considered, due to its heterogeneity. The difficulty of such data manifests itself in a penalty that has periodically been reported to affect the performance of detectors built on binary classifiers; this is known as cover source mismatch. It remains unclear how the performance drop that is associated with cover source mismatch is mitigated

Resumen
Cell migration is a behaviour critical to many key biological effects, including wound healing, cancerous cell invasion and morphogenesis, the development of an organism from an embryo. However, given that each of these situations is distinctly different and cells are extremely complicated biological objects, interest lies in more basic experiments which seek to remove conflating factors and present a less complex environment within which cell migration can be experimentally examined. These include in vitro studies like the scratch assay or circle migration assay, and ex vivo studies like t

Resumen
L'objectif de cette thèse était de proposer, puis de valider expérimentalement, un ensemble de méthodes algorithmiques permettant le remaillage parallèle de maillages distribués, en s'appuyant sur une méthode séquentielle de remaillage préexistante. Cet objectif a été atteint par étapes : définition de structures de données et de schémas de communication adaptés aux maillages distribués, permettant le déplacement à moindre coût des interfaces entre sous-domaines sur les processeurs d'une architecture à mémoire distribuée ; utilisation d'algorithmes de répartition dynamique de la charge adaptés

Resumen
Ce travail a pour objet l'application a un composite fortement heterogene d'un modele micro-macro variationnel pour les materiaux heterogenes a comportement non lineaire et a repartition aleatoire des heterogeneites. Ce modele, dit modele extremal heterogene, realise, a l'aide d'un parametre d'heterogeneite r, une transition continue entre les deux bornes, inferieure et superieure, de reuss-voigt-hill. Le modele est applique a la recherche du critere de resistance d'un mortier renforce de fibres metalliques (m. F. M. ). Le comportement des materiaux constitutifs est considere rigide-plastique

Some pericarpial proteins extracted from the jelly curd have been identified as a pectin methylesterase (PME), chitinase, thaumatin-like protein (TLP), two PR proteins, pathogenesis related-1(PR-1) and pathogenesis related-4 (PR-4). PR-4 was classified into two groups, Class I contains extra chitin binding domain (CBD) in N-ternimus and Class II has no such domain. cDNA fragment coding for Jelly fig

Resumen
博士<br>國立臺灣大學<br>資訊工程學研究所<br>102<br>It is often expensive to collect labeled data and we sometimes have large amounts of labeled data in a related domain. Without enough training data, some classifiers such as k-Nearest Neighbor (kNN) or Support Vector Machine (SVM) may fail to achieve good classification performance. In this thesis, we consider the problem of utilizing few labeled data samples in a target domain and the data samples in a source domain to improve data classification in the target domain. We assume that the source and target domains have different feature spaces. In addition, th
