We reported on one new series of light-emitting copolymers for polymer light-emitting devices (PLEDs), poly(dioctyl fluorene-codiphenyl oxadiazole)s (P(DOF-DPO)s). The device structure used in this study was composed of: indium tin oxide (ITO) anode/PEDOT:PSS ((polyethvlenedioxythiophene)–poly(styrene sulfonate)) as hole-transporting layer/P(DOF) or P(DOF-DPO) as emissive layer/calcium + alumin...

development of an intelligent huggable robot named ANTY (Fig.1) that will interact with hospitalized children to distract and support them during their stay in hospital. This robot is subject of a multidisciplinary project covering research opportunities not only in mechanical design, vision, speech and AI, but also in sociology and psychology. The main goal of the first phase is the developmen...

A multi-DOF ultrasonic motor developed in our previous study has significant potentials for dexterous actuation. The ultrasonic motor provides multiDOF rotation of a spherical rotor using three natural vibrations of a bar-shaped stator. In this paper, numerical analyses on the multi-DOF ultrasonic motor are conducted. First, a forward model of multi-DOF ultrasonic motor is developed considering...

We analyze the theories of gravity modified by a generic nonderivative potential built from the metric, under the minimal requirement of unbroken spatial rotations. Using the canonical analysis, we classify the potentials V according to the number of degrees of freedom (DoF) that propagate at the nonperturbative level. We then compare the nonperturbative results with the perturbative DoF propag...
