The vigorous development of artificial intelligence has had a profound and long-term impact on human production and life. It is a double-edged sword. While letting people enjoy the good life created by new technology, it also allows people to feel its negative effects, such as infringing on human privacy, and bringing new inequalities to human beings. Discussing the social responsibility of artificial intelligence has become a hot topic in academic circles in the past two years. This article starts with adopting the research framework of ISO 26000, comprehensively analyzing the problems of artificial intelligence social responsibility in theory and practice, and putting forward their own thinking. It is concluded that in the age of artificial intelligence, we will proceed from the seven themes of this standard to enhance the social responsibility of artificial intelligence, and ultimately achieve the sustainable development of artificial intelligence by adopting the social responsibility international standard ISO 26000,.

Most remote-sensing systems obtain terrain surface images from vertical observation by satellites and high-altitude aircrafts. However, this can be inadequate for subsurface geological image acquisition. Indeed, subsurface or under-surface geological information is more essential for geological and civil engineering. In this work, we proposed a subsurface geological feature recognition approach: first, cross-section geological images are captured horizontally by low-altitude UAV. Later, deep transfer learning model is trained to classify the type of geological mass exposed on the cross-section. We also examined different deep transfer learning models regarding their classification performances. The result suggests that Inception-ResNet-V2 based model outperformed others by reaching an overall accuracy of 99.72%.

To fulfill multiple constraints of desired range, terminal altitude, velocity and flight-path angle for hypersonic vehicles in the reentry terminal area, a finite-time convergent sliding mode guidance method is developed in this paper. The vehicles mass-point motion equations are established with the downrange as independent variable. A sliding mode, which can converge to zero at finite downrange value, is designed according to the formation of the finite-time convergent sliding mode. Thus it is effectively to be avoided to estimate time-to-go when the finite-time convergent sliding mode is utilized in guidance. The designed finite-downrange convergent sliding mode is applied in longitudinal guidance to ensure that the desired terminal altitude, flight-path angle and velocity can be satisfied at the terminal downrange arrived. The guidance commands of drag force and lift force in longitudinal plane are determined. With a rather high lift-to-drag ratio of hypersonic vehicles, extra life force needs to be consumed in lateral motion. Thus the lateral bank-reverse logic is designed based upon a constant heading error corridor for lateral bank reversing. Desired energy state and flight path characteristics can be achieved. The simulation results, given in Fig. 1-Fig. 5, and their analysis show preliminarily that the proposed guidance method can effectively deliver the hypersonic vehicle to the auto-landing interface with multiple terminal constraints satisfied.

The trajectory tracking for a non-holonomic mobile robot is addressed in this paper. Cascade control is implemented with a Sliding Mode controller for the outer loop and a Proportional-Integral-Derivative controller governing the inner loop. Linear Quadratic Regulator is further applied to the outer loop to optimize the controller's effort. The model is further analyzed based on various output performances such as trajectory tracking, reference tracking of linear and angular velocities, sliding surfaces of the controller, and its robustness. A comparative analysis with and without an optimal approach has been illustrated. Simulations are carried out on a virtual robotic simulator in LabVIEW.

A scheme consisting of only one current follower transconductance amplifier (CFTA) and four passive components is introduced for realizing the novel dual-mode universal biquadratic filter. The introduced filter can perform either in voltage-mode or current-mode, and can realize the highpass, bandpass and lowpass filter responses simultaneously without needing any element matching constraints. The natural angular frequency (omega(0)) and the quality factor (Q) of the filter can be tuned electronically by the transconductance gain of the CFTA. Computer simulations are used to confirm the workability of the proposed circuit.

Automatic excavators, which do not require direct operator intervention, have great advantages in terms of operator convenience and work efficiency, and are receiving a lot of attention. In order to improve the automatic work performance of an excavator, precise motion control of the upper operation part of the automatic excavator is essential. To do this, a model-based control algorithm for an automatic excavator, which is accompanied by a kinematic modeling process of the operation part, is newly designed in this paper. Based on sophisticated simulation, the characteristics of the proposed control algorithm are evaluated by comparing it with the existing proportional-integral-derivative (PID) controller.
