Book excerpt: La texture des surfaces est tactilement perçue principalement par les vibrations générées lors du glissement de nos doigts sur celles-ci. Malgré sa prévalence quotidienne, l'étude de l'interaction du doigt avec une texture, dans le cadre de la réalité virtuelle, n'a pas été approfondie en détail. Cette thèse explore une partie des facteurs qui contribuent à la mécanique de l'interaction entre un doigt et une surface avec pour objectif sa reproduction artificielle. L'enregistrement et la reproduction des textures tactiles sont premièrement discutés, accompagnés de la conception d'un appareil capable de précisément mesurer la force d'interaction émanant de la friction d'un doigt qui glisse. Le même dispositif piézoélectrique fut employé pour déformer à haute vitesse le bout du doigt, dans le but de reproduire la présence d'une texture. Ce travail est une nouvelle approche pour simuler la rugosité et la texture d'une surface virtuelle. La question de l'enregistrement et de la reproduction des surfaces texturées a motivé l'étude du comportement mécanique du bout du doigt. Cette étude révèle que le bout des doigts se comporte comme un ressort élastique dans les basses fréquences, et qu'après une fréquence de coupure d'environ 100 Hz, la réponse est dominée par l'amortissement visqueux, un fait qui n'a jamais été directement observé auparavant. Ensuite, les spécificités des signaux vibratoires créés par le frottement d'un doigt sur plusieurs textures furent analysées. L'expression des fluctuations de la force de friction en fonction de l'espace plutôt que du temps, indique que plusieurs caractéristiques du signal peuvent jouer un rôle majeur dans la perception tactile des textures.Cette thèse met en lumière l'importance de la mécanique et de la biomécanique pendant l'exploration haptique des surfaces et leur potentielle contribution à la perception. Collectivement, les résultats présentés dans cette thèse sont utiles pour la conception de meilleurs systèmes de réalité virtuelle et à d'autres applications.

Download or read book Speech to Speech Translation written by Yutaka Kidawara and published by Springer Nature. This book was released on 2019-11-22 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the readers with retrospective and prospective views with detailed explanations of component technologies, speech recognition, language translation and speech synthesis. Speech-to-speech translation system (S2S) enables to break language barriers, i.e., communicate each other between any pair of person on the glove, which is one of extreme dreams of humankind. People, society, and economy connected by S2S will demonstrate explosive growth without exception. In 1986, Japan initiated basic research of S2S, then the idea spread world-wide and were explored deeply by researchers during three decades. Now, we see S2S application on smartphone/tablet around the world. Computational resources such as processors, memories, wireless communication accelerate this computation-intensive systems and accumulation of digital data of speech and language encourage recent approaches based on machine learning. Through field experiments after long research in laboratories, S2S systems are being well-developed and now ready to utilized in daily life. Unique chapter of this book is end-2-end evaluation by comparing system’s performance and human competence. The effectiveness of the system would be understood by the score of this evaluation. The book will end with one of the next focus of S2S will be technology of simultaneous interpretation for lecture, broadcast news and so on.

Download or read book Building and Using Comparable Corpora written by Serge Sharoff and published by Springer Science & Business Media. This book was released on 2013-12-13 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1990s saw a paradigm change in the use of corpus-driven methods in NLP. In the field of multilingual NLP (such as machine translation and terminology mining) this implied the use of parallel corpora. However, parallel resources are relatively scarce: many more texts are produced daily by native speakers of any given language than translated. This situation resulted in a natural drive towards the use of comparable corpora, i.e. non-parallel texts in the same domain or genre. Nevertheless, this research direction has not produced a single authoritative source suitable for researchers and students coming to the field. The proposed volume provides a reference source, identifying the state of the art in the field as well as future trends. The book is intended for specialists and students in natural language processing, machine translation and computer-assisted translation.

Download or read book Mission and Context written by Jione Havea and published by Rowman & Littlefield. This book was released on 2020-06-30 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mission is contrived from and performed over lived contexts, but the visions that guide and drive mission are oftentimes blinded by power, position, protection, and plenitude. This collection visits those matters with queering attention to the shadows that empires cast over the contexts of mission, and to the collusion and complicity of Christians and churches with empires past (as in the case of Rome) and present (as in the case of the United States of America). In the interests of those in mission fields who survived, but continue to agonize under the burdens of empires, the contributors to this work dare to re-vision the course and cause of mission. Writing from minoritized settings in Africa, Asia, the Americas, and Oceania, the authors interweave the principles and practices of mission with the opportunities in decolonial theology and hermeneutics, minoritized and migrant Christologies, repatriation and the courage to get up and get out, indigenous insights and wisdom, mission archives, stories of resistance and endurance in zones of contact and violence, restless souls and returning spirits, and life-centered spiritual (en)countering. In Mission and Context as with previous volumes in this series—empires do not have the final word, nor are they the final world.
