This research sought to examine the lived experiences and minds of entrepreneurs who had influenced society in ways beyond the domain of the private sector. An entrepreneur was defined as an individual who pursues opportunity or is driven by the perception of opportunity. It was proffered that a divide exists in our understanding of an entrepreneur—as person—and an entrepreneur—as business starter. To a great extent, this divide has limited exploration of the connections and benefits that entrepreneurial thinking might bring to education. This was a qualitative and interpretivist study based on interviews with a purposive sample of entrepreneurs who have had a major influence in private, public, and more generally in the plural sectors in and around Canada. Nine entrepreneurs were invited to tell their life stories, to provide their perceptions of how entrepreneurs think and to relate how they believed they had developed their skills. Using in-depth interviews, the researcher was able to discover, in part, the essence of how these entrepreneurs thought, how they made decisions, and how they viewed themselves and their world. The findings and insights add to the growing body of literature on entrepreneurship. The researcher argued that the dissertation had given light to the lived experience of entrepreneurs. Understanding how these persons had become entrepreneurial and how they had recognized opportunities for their own mentorship were addressed by the research. How these entrepreneurs thought, their motivations, and interests, as well as how they perceived their role in the world provided valuable insights, especially as one seeks to understand how to cultivate or develop, nurture and encourage entrepreneurs, and to foster entrepreneurial behaviour throughout the education sector. The exploratory insights from these rich interviews serve to further foster fruitful conversations on potential alignments between the ways and thinking of entrepreneurs and educational systems.

This work contributes for the student to build the idea of algebra as language to express irregularities, that is one of the proposed issues by the National Curricular Parameters (PCNs) for the math teaching in the fourth cycle of high school, which contrasts, nowadays, with the scarcity of activities involving observed arithmetic progressions in at least twelve years of experience as a math teacher in these cycles. The elaboration of a teaching product, in the way of activity sheets that, through the recognizing of numerical and geometric patterns, takes the student to the comprehension of the concept of arithmetic progression which could be tested through the application of these activity sheets in two classrooms of the ninth year of high school in a public municipally school. The obtained results of these applications were analyzed and compared to the previous analyzes in raised hypothesis during the elaboration of the activity sheets, using, as investigation methodology, the Didactic Engineering. The students did the activities in groups of two or three, were well motivated and participated as principal character during the application of all steps proposed in the paper, which guaranteed the good development of the activity. In according to the evaluation learning, the students reaching the proposed goals and noting that the produced teaching material works. It is believed that the elaborated material can be useful for other teachers who want to develop, in their classes, arithmetic progressions through the recognizing of patterns, adapting it to the reality of their classrooms. This work contributes hugely to the author, bringing a big professional evolution that starts with the issue choice, continued in the elaboration of the didactic sequence and the application of the activity sheets and finished with the reflection of what have been done and is registered here. / A importância do desenvolvimento de progressões aritméticas que são sequências no ensino fundamental foi observada em situações de aprendizagem que os alunos puderam investigar e identificar padrões em sequências numéricas e geométricas, construindo a linguagem algébrica para descrevê-las. Esse trabalho contribui para que o aluno construa a ideia de álgebra como uma linguagem para expressar regularidades, que é um dos conteúdos propostos pelos Parâmetros Curriculares Nacionais (PCNs) para o ensino de Matemática no quarto ciclo do ensino fundamental, o qual contrasta, atualmente, com a escassez de atividades envolvendo progressões aritméticas constatada em pelo menos doze anos de experiência como professor de matemática nesses ciclos. A elaboração de um produto de ensino, na forma de folhas de atividades que, através do reconhecimento de padrões numéricos ou geométricos levam o estudante à compreensão do conceito de progressão aritmética pôde ser conferida através da aplicação dessas folhas de atividades em duas salas de 9º ano do ensino fundamental de uma escola municipal. Os resultados obtidos dessas aplicações foram analisados e comparados com as análises prévias em hipóteses levantadas durante a elaboração das folhas de atividades, usando, como metodologia de investigação, a Engenharia Didática. Os alunos realizaram as atividades em duplas ou em trios, se sentiram bem motivados e participaram como protagonistas durante a aplicação de todas as etapas propostas nas folhas, o que garantiu o bom desenvolvimento das atividades. De acordo com a avaliação do aprendizado, os alunos atingiram os objetivos propostos e constatou-se que o material de ensino produzido e aplicado funciona. Acredita-se que o material elaborado possa ser útil a outros professores que desejarem desenvolver, em suas aulas, progressões aritméticas através do reconhecimento de padrões, podendo adaptá-lo à realidade de suas turmas. Este trabalho contribuiu enormemente ao autor, trazendo uma grande evolução profissional que se iniciou na escolha do tema, permeou pela elaboração da sequência didática e pela aplicação das folhas de atividades e terminou pela reflexão sobre o que foi feito e se encontra registrado aqui.

Textual Entailment vise à capturer les principaux besoins d'inférence sémantique dans les applications de Traitement du Langage Naturel. Depuis 2005, dans la Textual Entailment reconnaissance tâche (RTE), les systèmes sont appelés à juger automatiquement si le sens d'une portion de texte, le texte - T, implique le sens d'un autre texte, l'hypothèse - H. Cette thèse nous nous intéressons au cas particulier de l'implication, l'implication de généralité. Pour nous, il ya différents types d'implication, nous introduisons le paradigme de l'implication textuelle en généralité, qui peut être définie comme l'implication d'une peine spécifique pour une phrase plus générale, dans ce contexte, le texte T implication Hypothèse H, car H est plus générale que T.Nous proposons des méthodes sans surveillance indépendante de la langue de reconnaissance de l'implication textuelle par la généralité, pour cela, nous présentons une mesure asymétrique informatif appelée Asymmetric simplifié InfoSimba, que nous combinons avec différentes mesures d'association asymétriques à reconnaître le cas spécifique de l'implication textuelle par la généralité.Cette thèse, nous introduisons un nouveau concept d'implication, les implications de généralité, en conséquence, le nouveau concept d'implications de la reconnaissance par la généralité, une nouvelle orientation de la recherche en Traitement du Langage Naturel. / Textual Entailment aims at capturing major semantic inference needs across applications in Natural Language Processing. Since 2005, in the Textual Entailment recognition (RTE) task, systems are asked to automatically judge whether the meaning of a portion of text, the Text - T, entails the meaning of another text, the Hypothesis - H. This thesis we focus a particular case of entailment, entailment by generality. For us, there are various types of implication, we introduce the paradigm of Textual Entailment by Generality, which can be defined as the entailment from a specific sentence towards a more general sentence, in this context, the Text T entailment Hypothesis H, because H is more general than T. We propose methods unsupervised language-independent for Recognizing Textual Entailment by Generality, for this we present an Informative Asymmetric Measure called the Simplified Asymmetric InfoSimba, which we combine with different asymmetric association measures to recognizingthe specific case of Textual Entailment by Generality.This thesis, we introduce the new concept of implication, implications by generality, in consequence, the new concept of recognition implications by generality, a new direction of research in Natural Language Processing.

The goal of the thesis is being familiar with methods a techniques used in speech processing. Using the obtained knowledge I propose three JavaApplets demonstrating selected methods. In this thesis we can find the theoretical analysis of selected problems.

L’objectif de cette recherche est la création d’une plateforme en ligne qui permettrait d’examiner les différences individuelles de stratégies de traitement de l’information visuelle dans différentes tâches de catégorisation des visages. Le but d’une telle plateforme est de récolter des données de participants géographiquement dispersés et dont les habiletés en reconnaissance des visages sont variables. En effet, de nombreuses études ont montré qu’il existe de grande variabilité dans le spectre des habiletés à reconnaître les visages, allant de la prosopagnosie développementale (Susilo & Duchaine, 2013), un trouble de reconnaissance des visages en l’absence de lésion cérébrale, aux super-recognizers, des individus dont les habiletés en reconnaissance des visages sont au-dessus de la moyenne (Russell, Duchaine & Nakayama, 2009). Entre ces deux extrêmes, les habiletés en reconnaissance des visages dans la population normale varient. Afin de démontrer la faisabilité de la création d’une telle plateforme pour des individus d’habiletés très variables, nous avons adapté une tâche de reconnaissance de l’identité des visages de célébrités utilisant la méthode Bubbles (Gosselin & Schyns, 2001) et avons recruté 14 sujets contrôles et un sujet présentant une prosopagnosie développementale. Nous avons pu mettre en évidence l’importance des yeux et de la bouche dans l’identification des visages chez les sujets « normaux ». Les meilleurs participants semblent, au contraire, utiliser majoritairement le côté gauche du visage (l’œil gauche et le côté gauche de la bouche). / The present study aims to create a web-based platform that would examine individual differences in face processing strategies in different categorization tasks. The purpose of this platform is to collect data from geographically dispersed participants with variable face recognition abilities. Indeed, many studies have shown that there is high variability in the spectrum of face recognition ability, ranging from developmental prosopagnosia (Duchaine & Susilo, 2013), a disorder of face recognition in the absence of brain damage, to super-recognizers, individuals with extraordinary face recognition ability (Russell, Duchaine & Nakayama, 2009). Between these extremes, people vary substantially in their ability to recognize faces. To demonstrate the reliability of creating such a platform for individuals of widely varying abilities, we adapted a recognition task of the identity of famous faces using the Bubbles method (Gosselin & Schyns, 2001) and recruited 12 control subjects and a subject with developmental prosopagnosia. We were able to highlight the importance of the eyes and the mouth in face identification. The best observers seem mostly to use the left side of the face (left eye and the left side of the mouth).

This diploma thesis deals with the design and implementation of an electronic module for acoustic detection. The module has the task of detecting a predetermined acoustic signals through them learned classification model. The module is used mainly for security purposes. To identify and classify the proposed model using machine learning techniques. Given the possibility of retraining for a different set of sounds, the module becomes a universal sound detector. With acoustic sound using the digital MEMS microphone, for which it is designed and implemented conversion filter. The resulting system is implemented into firmware microcontroller with real time operating system. The various functions of the system are realized with regard to the possible optimization (less powerful MCU or battery power). The module transmits the detection results of the master station via Ethernet network. In the case of multiple modules connected to the network to create a distributed system, which is designed for precise time synchronization using PTP protocol defined by the IEEE-1588 standard.
