Non-contact anterior cruciate ligament (ACL) injuries are serious and debilitating, often resulting from the performance of evasive sides-stepping (Ssg) by team sport athletes. Previous laboratory based investigations of evasive Ssg have used generic visual stimuli to simulate realistic time and space constraints that athletes experience in the preparation(More)
This paper explores the use of the online digital world Second Life as an environment in which one can represent and explore three dimensional fractals, and in addition, present them to others in a collaborative and engaging fashion. Second Life at its core provides a means whereby multiple remote participants can engage with 3D geometry within a virtual(More)
a r t i c l e i n f o a b s t r a c t qwViz is a software package for interactive visualisation of the time-evolution of quantum walks on arbitrarily complex graphs. The package is written in C and uses OpenGL to generate graphics in real-time. The qwViz package can be used to directly simulate discrete-time quantum walks on undirected graphs when provided(More)
Using computer graphics and visualization algorithms, we extend in this work the results obtained analytically in [1], on the connectivity domains of alternated Julia sets, defined by switching the dynamics of two quadratic Julia sets. As proved in [1], the alternated Julia sets exhibit, as for polynomials of degree greater than two, the disconnectivity(More)
The paper attempts two tasks. The first is to provide a characterization of the social democratic approach which sets it in contrast to liberal democratic theories. This is pursued by contrasting the different interpretations of the ideal of equal respect which are associated with the two approaches. The second task is to establish that the social(More)
