In brief

Abstract

PAGE 560 Turkish researchers propose a novel mixture model for visible light communication systems that use multiple sources. The model provides sufficient flexibility to accurately model the received signal levels, enabling better system designs. The validity of the model has been empirically verified using real-life measurements. PAGE 542 Researchers from Nanjing, China, have developed an initial rotor alignment method for the position sensorless start-up of doubly salient electromagnetic machines. The method, “align and go”, uses electromagnetic pulses to align the rotors, looking for the most energetically favourable starting conformation. The findings are validated by experiment, showing the flexibility and effectiveness of the proposed method. SolidWorks plot of the measurement setup. Each PD shows the position respectively P1, P2 and P3. PAGE 531 A collaboration of researchers from China and Australia propose an independent path-based process recommendation algorithm to speed up biomedical process recommendation, whilst guaranteeing accuracy. The experimental results show the improvement of the proposed algorithm over current state-of-the-art. The full experiment result of “align and go” with the initial alignment pulse A+B+C−. PAGE 562 Researchers from Japan propose a novel THz-wave autocorrelator which is based on an optical delay line (ODL) and unitravelling-carrier photodiodes (UTC-PDs) for easy observation of optical waveforms. The waveform is delayed in the optical domain whilst it is autocorrelated in the THz domain. Demonstrations show the system working with sinusoidal optical waveforms with frequencies up to 300 GHz. Process models presented as a Petri net. PAGE 527 Researchers from China present a novel, 3-D printed waveguide step-twist integrated with a bandpass filter. The device has a centre frequency of 32 GHz and a bandwidth of 1 GHz. Measurements show good agreement with simulation, with insertion loss of 0.84 dB and a return loss better than 15 dB across the passband. Experimental configuration.
