Work from South Korea proposes a periodic trench structure, which was inserted into the InGaN/GaN MQW through e-beam lithography and dry etching process for strain relaxation and quantum cascade stark effect (QCSE) reduction. Results confirmed the periodic trench structure is an effective method of strain relaxation and QCSE reduction. Excessive reduction of the trench period, however, is found to be harmful.
Research from Spain and Germany discloses a method that allows design of both Peres and Toffoli reversible gates with n binary control lines of mixed polarity, at a lowest quantum cost and without using ancillary lines. Reversible circuits allow low-power realisations in the CMOS world and prepare the way for quantum computing, since quantum circuits must be reversible.
Continuum manipulators are subject to a set of non-linearities and uncertainties, making it difficult to build an accurate analytical model. Currently, the bionic arm placed on the Robotino mobile platform is controlled in an open-loop scheme using a joystick interface. Researchers in France and Cameroon propose the first functioning control scheme for this class of continuum manipulator.
Work in Italy presents a novel state-of-the-art re-identification approach for human defined discriminative signatures to re-identify a target moving across cameras. The approach uses image dissimilarities and poses the re-identification as a binary classification problem. Knowing if a particular person is present in a monitored area at a precise instant of time has implications for surveillance applications.
Silicon based MEMS technology has produced RF micro switches for the past two decades, however, its power handling capability beyond 10 watts has always been a challenge. Work in the US adopts laminate technology for RF microswitches, to realise high RF power handling capability; demonstrating 15 W at 1.9 GHz with low voltage control signal and switch latched at the desired state without power consumption.
