Development of an XML Web based motion capture data warehousing and translation system for collaborative animation projects
While motion capture has been hailed as a way to achieve extremely realistic animation in a cost-effective manner, many animators are reluctant to use it or to intermix it with keyframing techniques in situations where they are required to collaborate with other production personnel due to the lack of
consistent software performance. The myriad of different file formats and the performance of those
formats across different animation packages have limited the penetration of this technology into the
production environment. The author details the development of an ASP web based application which
archives segmented motion capture data into an intermediate XML format and then allows the users of
the system to dynamically retrieve the data in standard Biovision segmented data format (BVA),
Lightwave 3D motion dump format, and Adaptive Optics Associates (AOA) motion capture format. The
net result is a dynamic web enabled systems that allows users of Avid SoftImage 3D, AliasWavefront
Maya, Newteck LightWave 3D, and Kinetix 3D Studio Max to exchange segmented motion capture data
Application-driven visual computing towards industry 4.0 2018
245 p.La Tesis recoge contribuciones en tres campos: 1. Agentes Virtuales Interactivos: autónomos, modulares, escalables, ubicuos y atractivos para el usuario. Estos IVA pueden interactuar con los usuarios de manera natural.2. Entornos de RV/RA Inmersivos: RV en la planificación de la producción, el diseño de producto, la simulación de procesos, pruebas y verificación. El Operario Virtual muestra cómo la RV y los Co-bots pueden trabajar en un entorno seguro. En el Operario Aumentado la RA muestra información relevante al trabajador de una manera no intrusiva. 3. Gestión Interactiva de Modelos 3D: gestión online y visualización de modelos CAD multimedia, mediante conversión automática de modelos CAD a la Web. La tecnología Web3D permite la visualización e interacción de estos modelos en dispositivos móviles de baja potencia.Además, estas contribuciones han permitido analizar los desafíos presentados por Industry 4.0. La tesis ha contribuido a proporcionar una prueba de concepto para algunos de esos desafíos: en factores humanos, simulación, visualización e integración de modelos
Mining a Small Medical Data Set by Integrating the Decision Tree and t-test
[[abstract]]Although several researchers have used statistical methods to prove that aspiration followed by the injection of 95% ethanol left in situ (retention) is an effective treatment for ovarian endometriomas, very few discuss the different conditions that could generate different recovery rates for the patients. Therefore, this study adopts the statistical method and decision tree techniques together to analyze the postoperative status of ovarian endometriosis patients under different conditions. Since our collected data set is small, containing only 212 records, we use all of these data as the training data. Therefore, instead of using a resultant tree to generate rules directly, we use the value of each node as a cut point to generate all possible rules from the tree first. Then, using t-test, we verify the rules to discover some useful description rules after all possible rules from the tree have been generated. Experimental results show that our approach can find some new interesting knowledge about recurrent ovarian endometriomas under different conditions.[[journaltype]]國外[[incitationindex]]EI[[booktype]]紙本[[countrycodes]]FI
Development of a toolkit for component-based automation systems
From the earliest days of mass production in the automotive industry there has been a
progressive move towards the use of flexible manufacturing systems that cater for
product variants that meet market demands. In recent years this market has become
more demanding with pressures from legislation, globalisation and increased
customer expectations. This has lead to the current trends of mass customisation in
production.
In order to support this manufacturing systems are not only becoming more flexible†
to cope with the increased product variants, but also more agile‡ such that they may
respond more rapidly to market changes. Modularisation§ is widely used to increase
the agility of automation systems, such that they may be more readily reconfigured¶.
Also with globalisation into India and Asia semi-automatic machines (machines that
interact with human operators) are more frequently used to reduce capital outlay and
increase flexibility. There is an increasing need for tools and methodologies that
support this in order to improve design robustness, reduce design time and gain a
competitive edge in the market.
The research presented in this thesis is built upon the work from
COMPAG/COMPANION (COMponent- based Paradigm for AGile automation, and
COmmon Model for PArtNers in automatION), and as part of the BDA (Business
Driven Automation), SOCRADES (Service Oriented Cross-layer infrastructure for
Distributed smart Embedded deviceS), and IMC-AESOP (ArchitecturE for Service-
Oriented Process – monitoring and control) projects conducted at Loughborough
University UK.
This research details the design and implementation of a toolkit for building and
simulating automation systems comprising components with behaviour described
using Finite State Machines (FSM). The research focus is the development of the
engineering toolkit that can support the automation system lifecycle from initial
design through commissioning to maintenance and reconfiguration as well as the
integration of a virtual human. This is achieved using a novel data structure that
supports component definitions for control, simulation, maintenance and the novel
integration of a virtual human into the automation system operation
The Object of Platform Studies: Relational Materialities and the Social Platform (the case of the Nintendo Wii)
Racing the Beam: The Atari Video Computer System,by Ian Bogost and Nick Montfort, inaugurated thePlatform Studies series at MIT Press in 2009.We’ve coauthored a new book in the series, Codename: Revolution: the Nintendo Wii Video Game Console. Platform studies is a quintessentially Digital Humanities approach, since it’s explicitly focused on the interrelationship of computing and cultural expression. According to the series preface, the goal of platform studies is “to consider the lowest level of computing systems and to understand how these systems relate to culture and creativity.”In practice, this involves paying close attentionto specific hardware and software interactions--to the vertical relationships between a platform’s multilayered materialities (Hayles; Kirschenbaum),from transistors to code to cultural reception. Any given act of platform-studies analysis may focus for example on the relationship between the chipset and the OS, or between the graphics processor and display parameters or game developers’ designs.In computing terms, platform is an abstraction(Bogost and Montfort), a pragmatic frame placed around whatever hardware-and-software configuration is required in order to build or run certain specificapplications (including creative works). The object of platform studies is thus a shifting series of possibility spaces, any number of dynamic thresholds between discrete levels of a system
