Industrial control systems (ICS) have become increasingly vulnerable to security risks due to the proliferation of network applications. Intrusion detection systems (IDS) are employed to safeguard ICS from hostile attacks. While machine learning-based methods perform well in intrusion detection tasks, combining multiple machine learning classifiers can further increase the detection accuracy. Confidence calibration is a technique developed to enable a machine learning model to produce prediction results along with more accurate proximate correctness likelihood. This study proposes a dynamic ensemble method that utilizes confidence calibration and a zeroth layer neural net classifier to create a semi-stacked ensemble model, while weighted cross-entropy loss is employed to balanced training samples. We tested our method on two real ICS cybersecurity datasets and achieved accuracy that matches traditional aggregating ensembles like voting and stacking while significantly reducing inference computation. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Most engineering design optimization problems are complex and expensive multi-objective optimization problems with multiple constraints. This paper proposes an improved surrogate-based multi-objective optimization algorithm (SBMO) using an adaptive weight vector generation method to address them. The main idea of the improved SBMO is to update the weight vectors of sub-problems adaptively according to the shape of the current Pareto front (PF) at each iteration while using SBMO to obtain Pareto optimal solutions. First, the improved SBMO decomposes a multi-objective optimization problem into a set of single-objective optimization sub-problems and builds surrogate models for each objective. Second, solutions are obtained by solving the acquisition problems for the sub-problems under the infill-sampling criteria. Third, all the solutions obtained will be evaluated and used to update the surrogate models to share the search information. At each iteration, the improved SBMO will divide the topology of the current PF evenly and select random points between the segment points. Well-distributed weight vectors will be generated based on the random points. This weight vector generation method can significantly improve the distribution of Pareto optimal solutions. The studies on benchmark test instances and aerodynamic design optimization of an airfoil indicate that the improved SBMO can obtain Pareto optimal solutions with better distribution than SBMO in a small number of sample points, and offers great potential to solve an expensive multi-objective optimization problem.

The navigation performance of the ship model is generally studied by the hydrodynamic parameters of ship models with the help of test chamber towing tanks or external waters. Considering the difference among the conditions of the indoor field towing tank or the outer field water area and the actual sea state, to solve the problem of the large-scale ship model series test under the actual sea state in this article, a large-scale ship model measurement and the control system was designed, including heading control system, controller, propeller propulsion device, rudder actuator and power supply module and others. It is used to test the maneuvering performance of large-scale ship models in the sea. On this basis, the reliability and effectiveness of the system were verified by testing the speed and maneuverability of the model in open water. © Published under licence by IOP Publishing Ltd.

Adhesive materials have excellent properties and are expected to be used in various industrial situations. However, the concentrated stress at the edge of the adhesive material will induce cracks and reduce the pull-off force. In this paper, the finite element method is used to study the delamination of elastomers with circular and square sections. A method to suppress the edge crack by adjusting the in-plane modulus is provided to improve the pull-off force. The packing ratio and interface stress uniformity of the elastomer arrays of two cross-sections are further compared. © 2023 The authors and IOS Press.

Aiming at the problem of assembly sequence planning of servo motor components, a method based on particle swarm algorithm to optimize the assembly sequence of servo motor components is proposed according to the characteristics of the assembly problem. This method redefines the related operations of velocity and position in particle swarm optimization. This paper evaluates the assembly sequence in terms of geometric feasibility and factors affecting the assembly process. The geometric interference information of the part is expressed by establishing the interference matrix. The objective function with the assembly tool and assembly direction as the evaluation index is established. Finally, the objective function is combined with the particle swarm algorithm, and the optimal assembly sequence of the servo motor components is obtained, which proves the effectiveness of the method. © 2023 SPIE.

Bionic impeller blades can improve cavitation performance of waterjets. A Special kind of bionic impeller with non-smooth leading edge is designed to improve the NPSH (net positive suction head) performance of waterjets. Based on the cavitation experiment of the waterjet with original impeller, a reliable CFD method using the commercial software StarCCM+ is verified. The detailed flow field of the bionic blades is obtained by simulating the viscous flow field. The stream line, pressure distribution and vortex reveal the mechanism of bionic blades flow adjustment. The influence of bionic impeller factors, which are the amplitude, the interval and the phase, on cavitation performance is systematically studied. The area and volume of the blade cavitation pattern is used to characterize the blade cavitation performance. An efficient method of cavitation pattern recognition is proposed to determine the information of the blade cavitation pattern accurately. A feasible cavitation-adjustment method is proposed to improve the hydraulic performance by optimizing the cavitation distribution and strength. © Published under licence by IOP Publishing Ltd.
