Purpose: As cyber-attacks continue to grow, organisations adopting the internet-of-things (IoT) have continued to react to security concerns that threaten their businesses within the current highly competitive environment. Many recorded industrial cyber-attacks have successfully beaten technical security solutions by exploiting human-factor vulnerabilities related to security knowledge and skills and manipulating human elements into inadvertently conveying access to critical industrial assets. Knowledge and skill capabilities contribute to human analytical proficiencies for enhanced cybersecurity readiness. Thus, a human-factored security endeavour is required to investigate the capabilities of the human constituents (workforce) to appropriately recognise and respond to cyber intrusion events within the industrial control system (ICS) environment. Design/methodology/approach: A quantitative approach (statistical analysis) is adopted to provide an approach to quantify the potential cybersecurity capability aptitudes of industrial human actors, identify the least security-capable workforce in the operational domain with the greatest susceptibility likelihood to cyber-attacks (i.e. weakest link) and guide the enhancement of security assurance. To support these objectives, a Human-factored Cyber Security Capability Evaluation approach is presented using conceptual analysis techniques. Findings: Using a test scenario, the approach demonstrates the capacity to proffer an efficient evaluation of workforce security knowledge and skills capabilities and the identification of weakest link in the workforce. Practical implications: The approach can enable organisations to gain better workforce security perspectives like security-consciousness, alertness and response aptitudes, thus guiding organisations into adopting strategic means of appropriating security remediation outlines, scopes and resources without undue wastes or redundancies.

This paper proposes a method for certifying the local asymptotic stability of a given nonlinear Ordinary Differential Equation (ODE) by using Sum-of-Squares (SOS) programming to search for a partially quadratic Lyapunov Function (LF). The proposed method is particularly well suited to the stability analysis of ODEs with high dimensional state spaces. This is due to the fact that partially quadratic LFs are parametrized by fewer decision variables when compared with general SOS LFs. The main contribution of this paper is using the Center Manifold Theorem to show that partially quadratic LFs that certify the local asymptotic stability of a given ODE exist under certain conditions.

Since piezoelectric actuating mechanism generally operate in high frequency response state, fatigue life has become an important factor influencing the performance and reliability of the entire drive mechanism. In order to investigate whether the designed piezoelectric ceramic actuator meets the active control requirements of the aero-engine, the paper analyzes the fatigue characteristics and fatigue life of the piezoelectric ceramic materials and the micro displacement amplification mechanism with finite element analysis softwareˈ and the optimal spacing value is obtained by studying the effect of the flexible hinge spacing on the fatigue characteristics of the displacement amplifier. And then, the fatigue life of the displacement amplifier is analyzed based on the drive load spectrum of the aircraft during simulated flight, whose result is 340.93 hours. Finally, the fatigue life of the piezoelectric actuating mechanism is 32 minutes when loaded with full power, which meets the design target initially.

During the movement of technological mechanisms under load, the electric drive must form a moment that would ensure a trouble-free mode of operation of both the technological mechanism and the electric drive. Modern research in vibroreology suggests that the destruction of intermolecular forces in the working environment during the application of vibration, which is manifested in the relative motion of the layers of the structured environment, leads to the destruction of bonds in the structure, reducing friction and adhesion, yield strength. This creates the conditions for the manifestation of current at lower shear stresses. During the analysis of physicochemical processes occurring in the working body with the working environment during downtime, it was found that for the complete destruction of the structure requires anisotropic regime of variable frequency and moment of vibration. The reduction of plastic viscosity in this case is achieved by destroying the structure of the medium. © 2021 IEEE.

The paper shows that the existing methods for determining steel losses of an induction machine are suitable only for the initial rectilinear (unsaturated) section of the magnetization curve, which gives a significant error in the saturation mode, or contain a large number of unknown elements, which makes it cumbersome and difficult to use the results in practical purposes. The proposed method is a further development of the well-known approach to determining steel losses. This takes into account the change in the magnetization inductance. This allows it to be used in high saturation mode. The expressions for determining steel losses are presented as a function of magnetic flux, EMF and current, which makes them suitable for practical use.

Independent smart cars are one of the applications of generic technology sets used to improve vehicle independence driving features, partially or completely. Often, real solutions refer to some mobile robot technologies and, this paper regards independent cars as platforms of mobile robots. We present the implementation and testing for two smart cars models. These are equiped with various sensor technologies to keep the mid lane car going (as the function of the Lane Keeping Assist) and to have a desired distance between the car and the car preceding it (as the function of the Adaptive Cruise control). Furthermore, it can avoid collision detection and collision on the road. The strategy for the control of the smart car is relies on algorithms, which are implemented by switching, where, algorithm 1 is designed based on the RST algorithm and algorithm 2 is multi-position. The efficiency and benefits of the strategies showed are proved by experiments with smart cars. © 2019 IEEE.

An adaptive forward-backward-forward splitting algorithm for solving pseudo-monotone inclusions

In this paper, we propose an adaptive forward-backward-forward splitting algorithm for finding a zero of a pseudo-monotone operator which is split as a sum of three operators: the first is continuous single-valued, the second is Lipschitzian, and the third is maximally monotone. This setting covers, in particular, constrained minimization scenarios, such as problems having smooth and convex functional constraints (e.g., quadratically constrained quadratic programs) or problems with a pseudo-convex objective function minimized over a simple closed convex set (e.g., quadratic over linear fractional programs). For the general problem, we design a forward-backward-forward splitting type method based on novel adaptive stepsize strategies. Under an additional generalized Lipschitz property of the first operator, sublinear convergence rate is derived for the sequence generated by our adaptive algorithm. Moreover, if the sum is uniformly pseudo-monotone, linear/sublinear rates are derived depending on the parameter of uniform pseudo-monotonicity. Preliminary numerical experiments demonstrate the good performance of our method when compared to some existing optimization methods and software. © 2025, CC BY.

In the recent decade, electronic technology gets advanced day by day the methodologies too should update. For the purpose of ranging various methods such Radio Detection and Ranging (RADAR), Light Detection and Ranging (LIDAR) and Sonic Navigation and Ranging (SONAR) etc. are used. Later, by adapting the earlier technologies and further modifying the purposes of detection and ranging in navigation, the technology of Sonic Detection and Ranging (SODAR) is used in modern robotics. The SODAR can be defined as a child of SONAR and also a twin of Echo sounder. The echo-sounder is used only for ranging. But the SODAR use the low-frequency wave of 33 kHz to measure the underwater depth and also to detect the objects below the water medium. So, this work comprises the designing of a system to evaluate the Object Detection and Ranging for Autonomous Navigation of Mobile Robots. © 2021, CC BY-NC-ND.

A pneumatic model of a fingertip haptic device (FHD) had been previously tested in virtual reality allowing the perception of different materials with a promising result. However, numerous drawbacks were noted in this design, including bulky size, less portability, and discomfort. In this paper, FHD is redesigned to provide haptic feedback for human meniscus palpation. A user study was performed to evaluate the effectiveness of the redesigned FHD. The study showed that the redesigned model could successfully provide a more evident perception of different stiffness levels but it compromised the comfort of the user when mounted on the finger for long periods. © 2023 World Scientific Publishing Company.
