Adyanthaya, S. (author), Geilen, M. (author), Basten, T. (author), Voeten, J. (author), Schiffelers, R. (author)We present a three-step binding algorithm for applications in the form of directed acyclic graphs (DAGs) of tasks with deadlines, that need to be bound to a shared memory multiprocessor platform. The aim of the algorithm is to obtain a good binding that results in low makespans of the schedules of the DAGs. It first clusters tasks assuming...conference paper 2016

(author)Ambipolar transistors typically suffer from large off-current inherently due to ambipolar conduction. Using a tri-gate transistor it is shown that it is possible to electrostatically switch ambipolar polymer transistors from ambipolar to unipolar mode. In unipolar mode, symmetric characteristics with an on/off current ratio of larger than 105...article 2016
