In brief

Abstract

PAGE 413 A portable in-ear brain-computer interface (BCI) is fabricated for generating and monitoring neural responses in work from Korea. The device is inexpensive, unobtrusive and avoids applying electrodes to the scalp, which can cause discomfort. The BCI is shown to efficiently and accurately record changes in electroencephalogram (EEG) signals in response to hearing different frequencies. PAGE 433 Researchers in China propose a control strategy for railways lines to regulate the energy transferred to traction grids. A single-phase traction rectifier is used to make the train become actively involved in renewable energy generation through regenerative braking. This control scheme can be used for smart grid networks on railway lines. A portable, lightweight and unobtrusive brain-computer interface for biomedical monitoring. PAGE 420 Work from Argentina presents a single instruction, multiple data processor (SIMD) for energy-aware embedded visual processing. The architecture of the chip is designed for dynamic voltage/frequency scaling and achieves good performance with efficient dynamic energy dissipation. The chip can be used in visual processing applications, such as for autonomous vehicle navigation. Controlling energy transfer in railway lines using a single-phase traction rectifier. PAGE 430 A direct laser performance comparison between single- and dual-heatspreader semiconductor disk laser configurations is made in work from the USA. The second heatspreader facilitates heat dissipation and increases the thermal rollover pump power. The design is proposed to be a suitable alternative to diamond-based materials for vertical external-cavity surface-emitting laser applications. A SIMD chip with a designed architecture for visual processing applications. PAGE 418 Researchers in Mexico report a compact spin-wave logic cell based on a single magnonic waveguide as a single channel multiport interference-based element. The spin-wave logic cell is based on a two-port parallel excitation configuration and can be used in functional electronics free of electric charges, while avoiding the Joule heating losses. Dual-heatspreaders in disk lasers are shown to give efficient heat dissipation and increased power to the rollover pump. A spin-wave logic cell for functional electronics free of electronic charges is proposed.
