El presente estudio tiene como objetivo resaltar la importancia de la educación virtual en una sociedad red, en el que el conocimiento, la innovación, la información y el acceso a las tecnologías constituyen los elementos centrales para el desarrollo. En este contexto, la educación virtual se convierte en un elemento clave para potenciar el aprendizaje permanente, para fortalecer habilidades de comunicación, cooperación y colaboración en red a través de los medios y herramientas que las tecnologías de información y comunicación nos proporciona; esta modalidad implica una serie de cambios, entre los que se destacan (a) los nuevos roles que deben desempeñar los docentes especialistas, docentes tutores y estudiantes, así como (b) la reestructuración de las instituciones educativas, y (c) los nuevos servicios que se ofrecen a los estudiantes. La demanda por las actividades formativas en la modalidad virtual se ve auspiciosa. Sin embargo, para lograr un verdadero y eficiente crecimiento se requiere tomar acciones que permitan disminuir y prevenir los índices de deserción, lo que repercutirá en beneficios tanto para el estudiante, la institución educativa como el sistema educativo y la sociedad en general. Los programas de acogida integrales, que consideren los aspectos académicos y no académicos, entre los que destacan los factores personales y sociales, serán determinantes para lograr una mejor adaptación del estudiante y así afianzar el compromiso asumido para con su formación y con la institución educativa. / Tesis

Currently, games with rich environments allowing a wide range of possible interactions and supporting a large number of physical simulations make use of a large number of scripts and bespoke physical simulations, adapted to fit the needs of the game. This thesis proposes a methodology that can be used to tie together various different physical simulations, both off-the-shelf and bespoke, such as rigid body physics, electrical and magnetic simulations to give something greater than the sum of the individual parts. We present a notation for designing the overall physical simulation and a means for the different parts to interact. Experiments using an implementation of the methodology containing electricity, rigid body simulation, magnetics (including electro-magnetics), buoyancy and sound show that it is possible to model everyday objects such an electric motor or a doorbell. These object work ‘as expected’, without the need for special scripts and new, originally unexpected, interactions are possible without further modification of the experiment setup.

This study explores the nature of conflict in virtual communication in the course of inter-organisational collaborations. Conflict appears to exist inherently when organisations cooperate together because each company operates with different goals, norms and values, which are vital considerations for successful business collaborations. Special attention, therefore, needs to be paid to gaining a grounded understanding of conflict in the context of virtual communication in the interorganisational business collaborations of today. This research draws on fieldwork carried out over five months, using a multiple-case study approach, involving four cases of inter-organisational collaborations between a large high-tech corporation in Taiwan and its four supplier companies in Korea. In addition, participant observation was employed as the main method of data collection in this study, which allowed for this researcher to gain rich data in a direct way. The collected data included daily logs based on observations, in addition to interviews and documentation. This resulted in an extensive amount of useful information being gathered, which was analysed, categorised, interpreted, and summarised in relation to theory generalisation. In this inter-organisational research setting, it was found that three patterns of interorganisational conflict, namely: business strategic conflict, cultural conflict and organisational process conflict interact to influence participants’ communication media selection and, in turn, conflict is influenced by the selected media. Moreover, it was found that conflict is expressed in email communication in a stylised way that is significantly different from spoken conversation and it could lead to conflict escalation and the subsequent termination of business collaboration. Based on the research findings, a comprehensive framework was established to describe and explain the interrelations between conflict transformation and computer-mediated communication (CMC) in inter-organisational collaborations.

Mathematics, physics, biology, and computer science are combined to create computational modeling, which studies the behaviors and reactions of complex biomedical problems. Modern biomedical research relies significantly on realistic computational human models or “virtual humans�. Relevant study areas utilizing computational human models include electromagnetics, solid mechanics, fluid dynamics, optics, ultrasound propagation, thermal propagation, and automotive safety research. These and other applications provide ample justification for the realization of the Visible Human Project® (VHP)-Female v. 4.0, a new platform-independent full body electromagnetic computational model. Along with the VHP-Female v. 4.0, a realistic and anatomically justified Dynamic Breathing Sequence is developed. The creation of such model is essential to the development of biomedical devices and procedures that are affected by the dynamics of human breathing, such as Magnetic Resonance Imaging and the calculation of Specific Absorption Rate. The model can be used in numerous application, including Breath-Detection Radar for human search and rescue.

Virtual reality (VR) headsets are becoming more common and will require evolving input mechanisms to support a growing range of applications. Because VR devices require users to wear head-mounted displays, there are accomodations that must be made in order to support specific input devices. One such device, a keyboard, serves as a useful tool for text entry. Many users will require assistance towards using a keyboard when wearing a head-mounted display. Developers have explored new mechanisms to overcome the challenges of text-entry for virtual reality. Several games have toyed with the idea of using motion controllers to provide a text entry mechanism, however few investigations have made on how to assist users in using a physical keyboard while wearing a head-mounted display. As an alternative to controller based text input, I propose that a software tool could facilitate the use of a physical keyboard in virtual reality. Using computer vision, a user€™s hands could be projected into the virtual world. With the ability to see the location of their hands relative to the keyboard, users will be able to type despite the obstruction caused by the head-mounted display (HMD). The viability of this approach was tested and the tool released as a plugin for the Unity development platform. The potential uses for the plugin go beyond text entry, and the project can be expanded to include many physical input devices.

"Global illumination (GI) rendering simulates the propagation of light through a 3D volume and its interaction with surfaces, dramatically increasing the fidelity of computer generated images. While off-line GI algorithms such as ray tracing and radiosity can generate physically accurate images, their rendering speeds are too slow for real-time applications. The many-light method is one of many novel emerging real-time global illumination algorithms. However, it requires many shadow maps to be generated for Virtual Point Light (VPL) visibility tests, which reduces its efficiency. Prior solutions restrict either the number or accuracy of shadow map updates, which may lower the accuracy of indirect illumination or prevent the rendering of fully dynamic scenes. In this thesis, we propose a hybrid real-time GI algorithm that utilizes an efficient Sparse Voxel Octree (SVO) ray marching algorithm for visibility tests instead of the shadow map generation step of the many-light algorithm. Our technique achieves high rendering fidelity at about 50 FPS, is highly scalable and can support thousands of VPLs generated on the fly. A survey of current real-time GI techniques as well as details of our implementation using OpenGL and Shader Model 5 are also presented."
