This paper is concerned with the stabilizability problem for discrete–time linear systems subject to a uniform quantization of the control set and to a regular state quantization, both fixed a priori. As it is well known, for quantized systems only weak (practical) stability properties can be achieved. Therefore, we focus on the existence and construction of quantized controllers capable of ste...

A tool is introduced that uses a novel technique to enable users to explore two-dimensional views of high dimensional gene expression data sets. Unlike other such tools, the interface is intuitive and efficient, allowing the user to easily select views that meet their requirements. The tool is tested on publicly available gene expression data sets and demonstrated to find views that show the se...

Modern pedagogies offer considerable promise for supporting improved student learning. Formative assessment can improve teaching and learning by using evidence of student understanding to adapt instruction. However, the current social and technical infrastructure of schooling often makes the teacher workload associated with such practices difficult to scale and sustain. We describe SPACE, an on...

The effective use of humanoid robots in space will depend upon the efficacy of interaction between humans and robots. The key to achieving this interaction is to provide the robot with sufficient skills for natural communication with humans so that humans can interact with the robot almost as though it were another human. This requires that a number of basic capabilities be incorporated into th...

The LAAS architecture has been developed over the years in a robotic context, to control autonomous robots from the low level control loop up to the mission planning and task execution. It defines a consistent set of methods and tools to enable and ease the integration of such diverse treatments. Similarities between the robotics domain and the space domain seem to indicate that, after being us...
