Data flow and computing resourses in large scale LED screens calculation and analysis is presented. It has been proved that due to specifics of LED screen control large data flows are born which for a reduction. Also, there is a demand for LED screen control hardware price reduction. By application of distributed computing by means of screen processors implementation in comes possible to reduce the data flow load on main processing unit. Thanks to this personal computer can be implemented for screen control as main processing unit. Due to above mentioned modifications PC becomes responsible only for data format unification. Main data processing is implemented in distributed network of screen processors. This further allows to use standard ethernet transmission and distribution equipment, leaving space for system future development.

Comprehensive and accurate information plays a key role in urban planning process. Recent developments in Information Communications Technologies (ICT) have provided considerable challenges and opportunities to improve the management of planning processes and make better use of planning information. However, data sharing and integration are always problematic for urban planning tasks because urban datasets are heterogeneous and scattered in different domains and organisations. It is stated that planners spend about 80 percent of their time to coordinate various datasets and analysis information (Singh 2004). The aim of this research is to develop a technical solution to providing information support for urban planning. The research will focus on planning data representation and integration in order to produce semantically rich urban models.

The thesis explores the complex relationship between modern audio technologies and the art of popular music through close scrutiny specific artefacts, a largely neglected area of musicological research. The detailed analyses presented here reveal the ways in which particular analogue and digital audio technologies are used, and how these have tended to shape and inform the musical and sonic characteristics of popular music recordings and related artefacts.

De 2006 à 2010, nous avons étudié le cas d’une université québécoise ayant implanté Moodle, une plateforme en ligne d’apprentissage. Celle-ci permet aux enseignants de créer un espace personnalisé sur Internet destiné à diffuser des ressources numériques à leurs étudiants, à interagir avec ceux-ci et à les faire participer à des activités d’apprentissage. Alors que plusieurs études se sont déjà penchées sur le potentiel pédagogique de ce type de technologie, nous l’avons plutôt abordé en tant qu’outil de travail des enseignants, en nous intéressant à l’émergence d’un processus de co-configuration dans un contexte où l’organisation implante et supporte à l’interne une technologie open source. Contrairement aux méthodologies de design participatif ou de développement logiciel itératif qui se préoccupent de l’implication des usagers dans les phases antérieures de la conception, les pratiques de co-configuration que nous décrivons concernent un produit existant qu’on adapte localement après son implantation. L'accessibilité au code source de Moodle ainsi que les échanges mutuels entre les développeurs et les usagers permettent à l'organisation utilisatrice de personnaliser l’outil tout au long de sa durée de vie, et non seulement lors de périodes circonscrites de design et de conception. Les problèmes rencontrés par les enseignants constituent donc le point de départ temporel de leurs interactions avec les développeurs à l’interne. Les usages en contexte réel de travail révèlent à la fois certaines structures organisationnelles difficilement perceptibles aux développeurs avant l’implantation et rendent plus visibles les pratiques hétérogènes des enseignants. En accroissant la capacité d’action des développeurs, l’accès au code source du logiciel crée un contexte plus favorable à la prise en compte des demandes des usagers, puisque les développeurs peuvent « localiser » plus facilement les problèmes rencontrés en allant regarder comment le logiciel a été programmé et comment il pourrait être modifié pour mieux répondre à leurs besoins. Le caractère incrémental des modifications apportées localement à Moodle fait en sorte que les développeurs puissent accommoder certains besoins très spécifiques - voire uniques - tout en s’assurant de répondre aux besoins de la majorité, en plus d’assurer la compatibilité entre la version locale et la version officielle du logiciel. D'un point de vue conceptuel, nous avons mobilisé la théorie de l'activité en tant que cadre d’analyse (Engeström, 1987). La théorie de l’activité considère le changement comme un processus de résolution de contradictions, c’est-à-dire une séquence d’événements autour desquels s’articule la transformation des pratiques. Les différents niveaux de contradiction permettent de mieux saisir les liens entre les nouveaux patterns d’interaction et les pratiques institutionnalisées, de même que les implications des changements pour les systèmes d’activité voisins.

This dissertation investigates deformable computer input device technologies to facilitate capturing complex physical-world gestures. By capturing the physical gestures and using appropriate haptics, it is possible to create virtual models using pinching and squeezing gestures similar to those used when sculpting clay. To date, most desktop modelling applications employ pointing devices that capture a single cursor location to manipulate a model with tedious sequential steps. One reason for this is developers have focused efforts on adopting applications to work with generic two-dimensional pointing devices, such as a mouse or digitising tablet. This is due to the difficulty of developing three-dimensional input technologies. In particular, deformable sensors capable of capturing natural sculpting techniques are undeveloped. / PhD Doctorate

The intention of this project is to research the potential of emergent technologies for developing sustainable composites for the building industry. It is divided into three parts: Part 1 Identifies emergent practices which are being applied to the development of new sustainable building prototypes such as developments using nanotechnologies, the influence of biomimetics, the development of intelligent interactive systems and the use of digital technologies to generate complex cellular structural systems. Part 2 Outlines existing processes involved in selecting and manufacturing prototypes, as many existing processes have been opportunistically applied to emergent practices to generate innovative sustainable prototypes. Part 3 By synthesising the research gathered in the previous parts of this thesis, this section documents the design process for developing a sustainable building system. The design is based on a minimal surface structure to reduce materiality and to optimise strength and its manufacturing process exploits emergent and existing technologies for its generation.
