Creating common ground: dialogues between performance and digital technologies

This article addresses the challenge of collaborative research between performance and digital technologies, seeking a model by which synthesis between the two aspects can be achieved. It draws upon the authors? experiences of projects where creative laboratory situations were used to support open-ended processes of exploration. The Performance Robotics project demonstrates how a cycle of iterative knowledge exchange was achieved through an embodiment exercise that developed unexpectedly. The Interactive Performance Telematics Project saw technical operators performing duets with dancers via animated sprites. Playful interaction in these projects enabled artists and technologists to find common ground on which to establish a rich dialogue for further research

Biorthogonal multiwavelets on the interval for solving multidimensional fractional optimal control problems with inequality constraint

This article proposes a new numerical approach for solving fractional optimal control problems including state and control inequality constraints using new biorthogonal multiwavelets. the properties of biorthogonal multiwavelets are first given. the Riemann-Liouville fractional integral operator for biorthogonal multiwavelets is utilized to reduce the solution of optimal control problems to a nonlinear programming one, to which existing, well-developed algorithms may be applied. in order to save the memory requirement and computation time, a threshold procedure is applied to obtain algebraic equations. the method is computationally very attractive and gives very accurate results
