Dyadic interactions are reflective of mutual engagement between their participants through different verbal and non-verbal voicing cues. This study aims to investigate the effect of these cues on continuous emotion recognition (CER) using speech and head motion data. We exploit the non-verbal vocalizations that are extracted from speech as a complementary source of information and investigate their effect for the CER problem using gaussian mixture and convolutional neural network based regression frameworks. Our methods are evaluated on the CreativeIT database, which consists of speech and full-body motion capture under dyadic interaction settings. Head motion, acoustic features of speech and histograms of non-verbal vocalizations are employed to estimate activation, valence and dominance attributes for the CER problem. Our experimental evaluations indicate a strong improvement of CER performance, especially of the activation attribute, with the use of non-verbal vocalization cues of speech.

Wireless Sensor Network (WSN) is a physical bridge that connects the real world to the digital world. Due to recent advances in an Internet of things and Industrial 4.0, more extensive WSN devices are used in industries ranging from the aerospace system, smart grid, Unmanned Aerial Vehicle (UAV) and drone application to the military investigation. However, due to the nature of WSNs, attackers can easily deploy various security threats to make WSN network vulnerable and unstable. The easiest way to attack WSN network is through the jamming attack with a little bit knowledge of targeted communication system. Standardisation of wireless communications used in various industries makes the attackers easy to design a smart reactive jamming device. In this paper, a new method using a timing channel is proposed to defeat the reactive jammer. To validate the proposed method, a smart reactive jamming device, a transmitter and a receiver are implemented in hardware. Test results are presented, showing how the method can defeat the reactive jamming attack.

The move towards more electric aircraft (MEA) is revolutionizing major elements of the traditional aircraft design process. Manufacturers are trying to better utilize the opportunities, for example, distributed aircraft control and the higher voltage electrical power system, which the MEA offers for designing lighter, more functional and more environmentally friendly aircraft. This has seen a move away from the traditional heuristic design approach to instead consider a wider range of design possibilities. This move towards solving multi-objective optimization problems, that initially generate all possible design solutions and then converge to the most practically optimal one, via the application of operating constraints, is most evident at the actuator system level and at both the control and power system architecture level. This contribution not only provides an overview of evolving approaches to MEA design but also more specifically concentrates on the safety and reliability aspects embedded within the design process.

A fully differential CMOS folded cascode operational amplifier is presented. It uses gain boosting technique on both NMOS and PMOS branch to enhance total gain. New current-sink topology is used to maximally enhance the open-loop gain as well as not to deteriorate the output swing badly. Local small area but good-performance CT-CMFB is adopted in gain-boosted auxiliary amplifier to optimize both area cost and calibration performance. An improved SC-CMFB is used on total amplifier output to stabilize the output common mode node voltage as well as not to impact differential gain performance. Designed in low-cost UMC 110 nm process with a 5V supply voltage, simulation results show DC gain of 164.1 dB and a phase margin of 63 degree at a unity gain bandwidth of 17.09 MHz. The static current is 174 uA along with achieved PSRR of 186.5dB, making it suitable in high-performance Delta-Sigma ADCs.

Active neutral-point clamped five-level(ANPC-5L) inverter is an attractive topology for high-power medium-voltage filed. Aiming at the capacitor voltage balance of ANPC-5L, this paper proposes a hybrid SVM modulation algorithm based on g-h coordinate system without judging sector nor lots of trigonometric function calculation. To realize flying capacitor voltage and dc-link capacitor voltage balance, the appropriate redundancy vector sequences are chosen by judging the current working mode. Simulation results are presented to verify the validity of this method in MATLAB.

In this paper, trajectory tracking control for autonomous helicopters, which are designed for aeromagnetic survey, is investigated. Since magnetometers towed to the helicopters receive better signals, we consider an unmanned autonomous helicopter with towed unknown slung load, which result in time-varying external disturbances exerting on both thrusts and control torques. Besides, inertial parameters in the helicopter model and external disturbances are also allowed to be unknown. An adaptive filtered backstepping control algorithm is presented. The effects of parameter uncertainties and external disturbances are compensated by introducing additional estimates of their bounds in control laws and robust terms in parameter update laws. It is shown that the proposed control scheme can achieve the ultimate bounded tracking effectively.

Single-phase traditional bridged active power factor corrector (APFC) can utilize analog controller or digital controller, and the voltage drop of noninductive shunt resistor represents the instantaneous value of inductor current for current inner loop control. This method can be directly used in quasi-bridgeless APFC for large output power. In order to adapt to the developing trend of high frequency in APFC, it is necessary to use an AC inductor with a low inductance. Under this condition, the above scheme for measuring the inductor current based on the voltage drop of the shunt resistor is no longer applicable, so the original topology needs to be improved. At the same time, in view of the fast response speed and high immunity of the one cycle controller (OCC), a quasi-bridgeless APFC circuit suitable for low inductances is proposed in this paper. After small-signal analysis model of the topology is established, the voltage compensator is designed based on one cycle control. Finally, the 1.0kW quasi-bridgeless APFC circuit is realized by using IRl155S as the analog controller.

The smart electricity meter (SEM) is a critical element of the smart grid, so power supply company and customers pay many attention to its service life. However, the existing reliability estimation methods can only provide an overall distribution of the SEM lifetime at certain conditions. To realize real-time prognostics and health management (PHM) of SEMs, this paper proposed a four-parameter model-based particle filter method. Firstly, an accelerated degradation testing is carried out to analyze the aging state of SEMs. Then, a four-parameter degradation model is proposed, and the fitting effectiveness is evaluated. Finally, particle filter is utilized to identify the model parameter and further obtain the RUL distribution of SEMs in service.

A two-dimensional model for fault arc in high-speed switch (HSS) in a hybrid direct current (DC) circuit breaker is developed based on magnetic-hydrodynamic theory to investigate the effect of metal vapour eroded from copper electrodes on fault arc. Different energy transfer mechanisms caused by electrode erosion, including electrode melting, vaporization and chemical reaction are considered. The plasma temperature and pressure rise are simulated. It is found that the effects of increased radiation and mass transfer due to copper vapour markedly cool down the central arc plasma whereas the influence of increased electrical conductivity is relatively small. The visualized simulation for the energy balance of fault arc shows that the presence of copper vapour has little influence on pressure rise.
