Juego de reflejos y habilidad para dispositivos con SO Android. Este proyecto consiste en la creación de un juego utilizando todas las herramientas posibles proporcionadas por Android. El juego se diseñará en 2 dimensiones, contará de un menú inicial donde se podrá elegir entre las opciones; Jugar, Puntuaciones y Ayuda. La parte de jugar llevará todo el peso de la aplicación y es donde se desarrollará toda la acción. Habrá que hacer transiciones entre distintas pantallas para cada uno de los distintos mini juegos. Además, llevará la cuenta del tiempo transcurrido con un preciso cronometro. El reloj de parará cuando se hayan terminado todas las pruebas. Si ha superado alguno de los mejores tiempos, guardaremos el record en el lugar que le corresponde. La parte de las puntuaciones mostrará los cinco mejores tiempos realizados en el juego. Estos tiempos seguirán guardados aún reiniciando la aplicación. La parte de ayuda mostrará las instrucciones de cada prueba; donde, cuándo, y de qué manera tienes que pulsar en cada momento. Hay que tener en cuenta que esta aplicación de desarrollará para versiones de Android 2.1 o superiores, así que es necesario basarse en API’s para estas versiones, y que no se debe necesitar nada más que el archivo de instalación (.apk) para poder disfrutar de el juego en cualquier terminal.

Crossing the Threshold, one of a series of advice and guidance publications, is designed to support use of the online e-Portfolio Implementation Toolkit and video case studies by those involved in wide-scale implementation of e-portfolios in their institutions. As the resources address the needs of both managers and practitioners, the publication has relevance for a wide range of readers in further and higher education and work-based learning. To assist the planning and effective management of a large-scale e-portfolio implementation, Crossing the Threshold follows the stages of an implementation journey with insights and guidance drawn from the toolkit and its supporting case studies. Links are provided throughout the publication to more detailed information in the two online resources.

The effects of complex boundary conditions on flows are represented by a volume force in the immersed boundary methods. The problem with this representation is that the volume force exhibits non-physical oscillations in moving boundary simulations. A smoothing technique for discrete delta functions has been developed in this paper to suppress the non-physical oscillations in the volume forces. We have found that the non-physical oscillations are mainly due to the fact that the derivatives of the regular discrete delta functions do not satisfy certain moment conditions. It has been shown that the smoothed discrete delta functions constructed in this paper have one-order higher derivative than the regular ones. Moreover, not only the smoothed discrete delta functions satisfy the first two discrete moment conditions, but also their derivatives satisfy one-order higher moment condition than the regular ones. The smoothed discrete delta functions are tested by three test cases: a one-dimensional heat equation with a moving singular force, a two-dimensional flow past an oscillating cylinder, and the vortex-induced vibration of a cylinder. The numerical examples in these cases demonstrate that the smoothed discrete delta functions can effectively suppress the non-physical oscillations in the volume forces and improve the accuracy of the immersed boundary method with direct forcing in moving boundary simulations.

A numerical 2D method for simulation of two-phase flows including phase change under microgravity conditions is presented in this paper, with a level set method being coupled with the moving mesh method in the double-staggered grid systems. When the grid lines bend very much in a curvilinear grid, great errors may be generated by using the collocated grid or the staggered grid. So the double-staggered grid was adopted in this paper. The level set method is used to track the liquid-vapor interface. The numerical analysis is fulfilled by solving the Navier-Stokes equations using the SIMPLER method, and the surface tension force is modeled by a continuum surface force approximation. A comparison of the numerical results obtained with different numerical strategies shows that the double-staggered grid moving-mesh method presented in this paper is more accurate than that used previously in the collocated grid system. Based on the method presented in this paper, the condensation of a single bubble in the cold water under different level of gravity is simulated. The results show that the condensation process under the normal gravity condition is different from the condensation process under microgravity conditions. The whole condensation time is much longer under the normal gravity than under the microgravity conditions.
