PAGE 476 Chinese researchers present an irregular pentagonal patch array antenna, featuring a multilayer structure to enable dual-band and multi-mode orbital angular momentum (OAM) generation. The proposed array has the potential generate 6 different OAMs in 3 frequency bands and may provide new ideas for generating multi-mode vortex electromagnetic waves. PAGE 482 A multiplier design technique for stochastic computing is presented. The proposed design offers exact output and latency in the order of 2N, where N = the input precision. Compared to state of the art deterministic methods, the proposed design is faster by a factor of 2N. The technique is verified by mathematical analysis and simulation. Schematic diagram of proposed antenna array's element PAGE 501 Researchers from the Republic of Korea demonstrate integrated one-dimensional optical phase arrays (OPAs) for wide-angle, two-dimensional beam-steering in a 26.5 mm2 area. The 2-D OPA consists of 16 1-D transversal steering OPAs, whose radiators have different grating periods – allowing assignment of different longitudinal angles. Carry save adder in proposed design for N = 3. Full adder and half adder are denoted by fa and ha respectively. PAGE 510 Chinese researchers present an edge-attention-based geodesic distance which can be applied to the simple linear iterative clustering (SLIC) framework for PolSAR image superpixel segmentation, improving performance without an increase in computational expense. Experiments show the superiority of the proposed distance both qualitatively and quantitatively. Structure and design parameters of the grating radiator. PAGE 490 A collaboration of Chinese researchers propose two schemes to help prevent unwanted sideslip by wheeled mobile robots when turning. A controller is proposed combining robust control and model predictive control. Together the longitudinal velocity can be adjusted according to the state of the robot, whilst the model predictive control is used to achieve path tracking.
