Sound is a crucial part of our life. Well-designed acoustic behaviors can lead to significant improvement in both physical and virtual interactions. In computer graphics, most existing methods focused primarily on improving the accuracy. It remained underexplored on how to develop efficient acoustic simulation algorithms for interactive practical applications. The challenges arise from the dilemma between expensive accurate simulations and fast feedback demanded by intuitive user interaction: traditional physics-based acoustic simulations are computationally expensive; yet, for end users to benefit from the simulations, it is crucial to give prompt feedback during interactions. In this thesis, I investigate how to develop efficient acoustic simulations for real-world applications such as immersive media and digital fabrication. To address the above-mentioned challenges, I leverage precomputation and optimization to significantly improve the speed while preserving the accuracy of complex acoustic phenomena. This work discusses three efforts along this research direction: First, to ease sound designer's workflow, we developed a fast keypoint-based precomputation algorithm to enable interactive acoustic transfer values in virtual sound simulations. Second, for realistic audio editing in 360° videos, we proposed an inverse material optimization based on fast sound simulation and a hybrid ambisonic audio synthesis that exploits the directional isotropy in spatial audios. Third, we devised a modular approach to efficiently simulate and optimize fabrication-ready acoustic filters, achieving orders of magnitudes speedup while maintaining the simulation accuracy. Through this series of projects, I demonstrate a wide range of applications made possible by efficient acoustic simulations.

Grid computing enables computers on different networks to share their resources in an organized way. Authorized users can deploy the resources as if they were in the same organization. This resource sharing environment is called a Virtual Organization (VOs). To enable an open Grid to support resource sharing between multiple heterogeneous VOs, an authorization policy management framework is required to support authorization for VOs using heterogeneous authorization systems. The challenges include dynamic Grid memberships, VO trust relationships, and heterogeneous authorization systems. / To solve these problems in a loose-coupling way, we propose a dynamic, distributive and heterogeneous authorization policy management framework. The framework is called Dynamic Policy Management Framework (DPMF). DPMF groups VOs of the same authorization systems to form a virtual cluster. Authorization policy management is divided into inter-cluster heterogeneous policy management, and intra-cluster homogeneous policy management. Inside a virtual cluster, the workloads of policy management can be distributed among the VOs according to their trust relationships. The Conflict Analysis with Partial Information (CAPI) mechanism is developed to make authorization decisions in open environments without complete policy information. A Heterogeneous Policy Management mechanism is developed for DPMF to support inter-cluster heterogeneous policy management. / Traditional authorization policy management frameworks work well in authorization for a single VO where the participating hosts agree to follow a global authorization system. However, they are not capable of authorization policy management for multiple VOs which deploys heterogeneous authorization systems. / Yu, Chiu Man. / "April 2007." / Adviser: Ng Kam Wing. / Source: Dissertation Abstracts International, Volume: 69-01, Section: B, page: 0447. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references (p. 200-206). / Electronic reproduction.

In this thesis, a scheme of using multiple controllers which handle multiple network devices has been proposed, while using OpenFlow controllers in the proactive operations paradigm, and this in order to face the problem of using a single controller in the SDN model, including the lack of reliability and scalability on such a model. The main characteristic of this new approach are focused on the ability to design a dynamic and highly programmable network, moving the intelligence from the underlying systems to the network itself through a controller. To evaluate the proper effects of this new approach, different dynamic and programmable networks that could simulate real scenarios and measure their performance contrasting the obtained results with the pragmatic theory has been implemented. The SDN (Software-Defined Network) controller (Open Daylight), has been utilized, and thoroughly examined. Different sort of nets has been worked out through diverse Open Daylight functionalities, either implementing the intelligence of the controller (bundle), or going through it by an outside intelligent application (External Orchestrator), and eventually sending it through Open Daylight (by making Open Daylight work as an interpreter/translator from its language to OpenFlow or another protocol language). Summing up, the scheme that has been proposed in this research which is the multiple-proactive mode approach and the single proactive controller has scored no packet loss at all, in which implies the strength of reliability of this scheme, while the multiple reactive mode approach has a range of 1-8% packet loss ratio and the single reactive mode approach has a range of 1-25% packet loss ratio. Also, in case of delay the improvement which was obtained from our approach scored an average reduction of 13% comparing with other tested schemes. Thus, these new and interesting technologies show an astonishing capability to add more efficiency in different types of Networks.

The neuroimaging findings showed that the RV acted positively In the function and dexterity of the upper limb, presenting a correlation with the white matter, and the higher the lesion area the worse the motor prognosis of the individuals after stroke.

Orientador: Dorival Campos Rossi / Banca: Olimpio José Pinheiro / Banca: Ivan Amaral Guerrini / Resumo: O presente trabalho versa acerca de outras formas de compreensão do design, dos projetos, processo e produtos como sendo virtuai e conforme uma abordagem transciplinar. É por meio do design de relações que se articulam as interfaces entre o design e as diversas disciplinas ou áreas do conhecimento de modo a se obter um design transdiciplinar ou transdesign. Destarte os produtos se configuram como não coisas ou não objetos virtuais, desde que a física quântica demonstrou a propriedade ondulatória da matéria e suas transformação em energia por meio da equação einsteiniana da mecânica relativística. A característica virtual ou rizomática dos objetos e produtos pode ser acessada, principalmente pelas suas atualizações digitais: as redes telemáticas, a Internet, o ciberespaço, a realidade virtual e o metaverso. O Second Life sendo um metaverso foi a plataforma escolhida para a construção de objetos e produtos virtuais, nos quais o design de relações (ou design virtual) articula ciências, filosofias, religiões, artes, tecnologias em arquitetura virtual, enfraquecendo os limites e barreiras disciplinares. A cibercepção (proposta por Roy Ascott) surge como elemento de sensibilidade no ato da criação com a utilização das ferramentas tecnológicas e telemáticas; sensibilidade esta que se expande ao nível psíquico da consciência do ser. Desta forma, podem-se estabelecer relações entre as ciências do psiquismo (as áreas psicológica e parapsicológica) e os meios de operação do metaverso (parte teórico-bibliográfica). Os objetivos deste trabalho são relacionar o Second Life com fenomenologia anômala (parapsicológica ou PSI); verificar se a teoria de Roy Ascott (ciberespaço) pode ou não ser corroborada a partir dessas relações e arquitetar um ambiente (não espaço) de interações virtuais para o grupo "Projetos Integrados de Pesquisa Online"-PIPOL, ...

It is through the relationship design that it articulates the interfaces between the design and the various disciplines or areas of knowledge in order to obtain a transdicplinar design or transdesign. Thus products become non-things or virtual non-objects, since quantum physics demonstrated the wave property of matter and its transformations into energy through the Einstein's relativistic mechanic equation. The virtual or rhizomatic feature of objects and products can be accessed, mainly by its digital actualizations: the telematic networks, the Internet, the cyberspace, the Virtual Reality and the metaverse. Second Life as a metaverse, was the platform chosen for the construction of objects and virtual products, in which Relationship Design (or Virtual Design) articulates sciences, philosophies, religions, arts, technologies into virtual architecture, weakening the disciplinary edges or barriers. Cyberception (proposed by Roy Ascott) arises as sensibility in the act of creation with the useof technologic and telematic tools; this sensibility expands to the psychic level of the Being's Consciousness. In this way one can stablish relationships between psychi sciences (in the psychologic and parapsychologic fields) and the modus operandi of the metaverse (theoretical-bibliographic part). The objectives of this work are to relate Second Life with the anomalous phenomenology (parapsychologic or PSI); to verify if Roy Ascott's theory (Cyberception) can or cannot be corroborated with those relations; and to architect na environment (non space) of virtual interactions for the group "Online Integrated Research Projects" - PIPOL, inside the Second Life Metaverse, based on the Virtual Architecture theory to build and present virtual products as ...

Low productivity and high costs have led to an increased interest for industrialized construction methods in Sweden. Several new construction systems have been developed to increase productivity and contribute to a more efficient construction process. Virtual Design and Construction is another term for efficient management of “design-construction projects, including the product (i.e., facilities), work processes and organization of the design - construction - operation team in order to support explicit and public business objectives” (CIFE, Stanford). By streamlining all these areas a cost-effective building process can be achieved. VeidekkeMAX, an open building system that has its roots in the Virtual Design and Construction, has been developed with a focus to increase productivity and be the most cost effective option while the keeping the flexibility in the design of various building components. This thesis has studied the repetitive construction process of the structural system of VeidekkeMax buildings. Vico Office have been used to automate the 5D planning of the construction process of the structural system. A reference project of a VeidekkeMAX building has been used as a basis for the development by comparisons and identifying similarities and differences with the project. The proposed method is based on the definition of a reference file in Vico Office that is supported by information and connecting structures from other software for the 5D design work process. In order to create a reliable procedure it must be designed with the knowledge of how the information is interpreted by different users. In addition the building parts need to be predefined and supplied with the correct specification id, a cost and activity recipe and be connected to a particular work process in the production schedule.

Determinando así que la mercado objetivo está dentro de las zonas urbanas, por el mejor acceso a las herramientas TIC’s, que pertenecen a las clases socioeconómicas B y C, por contar con una mejor capacidad de pago, y que su rango de edad está entre los 18 años a 30 años de edad. Así mismo se puedo conocer que existen actualmente cinco universidades en el mercado local, que ofrecen estudios de educación virtual. A través del análisis de la información recolectada, se logró definir que la mayoría del público objetivo (93%) requiere de material físico, para complementar sus estudios virtuales, siendo las separatas (40%) y los libros (32%) los más requeridos. Así también, un 88% del público objetivo, demanda también un docente para asesorías presenciales, al menos una vez por semana (34%) o quincenalmente (25%), reflejando el escaso tiempo que tienen para desplazarse. También requiere en su mayoría (95%) de un docente para asesorías virtuales, utilizando las vídeos llamadas como el medio de comunicación principal (41%), seguido del correo electrónico y redes sociales. Así mismo se comprobó que la carrera universitaria virtual, actualmente en el público objetivo, se asocia con los conceptos de inseguridad del aprendizaje y el bajo prestigio profesional, reflejando una idea del mercado actual. El trabajo de investigación muestra una viabilidad para la virtualización de la carrera de Administración, recomendando la utilización de diferentes estrategias del marketing mix, derivadas de las conclusiones. / Tesis
