Summary: Remanufacturing involves rebuilding a product using a combination of reused, repaired, and new parts, with disassembly as a key and labor-intensive process. Robotic disassembly is an attractive alternative but still requires manual planning due to the complexity of end-of-life products. The proposed method in this paper allows machines to plan disassembly by generating and manipulating specific matrices, providing a flexible and effective approach for dealing with complex mechanical structures.

Summary: The existing studies on SDSP primarily focus on sequential SDSP, which is inefficient for disassembling complex products. However, energy efficiency has not been given sufficient attention in SDSP, despite its critical role in environmental impact. Therefore, this research proposes a profit-oriented and energy-efficient multi-objective asynchronous parallel SDSP (PEAPSDSP) that optimizes disassembly time, energy consumption, and disassembly profit simultaneously. The proposed two-stage interactive multi-objective evolutionary algorithm (TS-IMOEA) successfully solves PEAPSDSP by obtaining potential non-dominated solutions (NDSs) in the first stage and improving their quality in the second stage using a novel search strategy. Numerical results of three different scale cases demonstrate the superior performance of TS-IMOEA in solving PEAPSDSP and the benefits of considering selective disassembly for value recovery.

Summary: In this study, a human-machine collaborative cell-level disassembly model of waste power battery modules (WPBMs) is proposed. The reliability and validity of the model are verified through a case study with WPBMs from the Tesla Model S. Two different disassembly schemes are obtained based on actual data, which optimize four objectives simultaneously. The proposed model provides decision-makers with additional options when considering the number of workers as an enterprise risk indicator.

Summary: This study proposes a complete simulated environment for a solar-powered UAV using a multi-objective genetic algorithm, including models for solar radiation, photovoltaic cells, battery, propeller, and dynamics. The energy captured by the UAV, battery charge, and electricity released are analyzed as multi-objective functions. The results show improvements of 5.79%, -7.00%, and 10.94% in the maximum energy output of the photovoltaic cells, battery release, and state of charge, respectively, compared to traditional optimization methods. Additionally, the solar-powered UAV achieves permanent flight under optimal conditions. These findings can contribute to the design of solar-powered UAVs with high energy efficiency.

Summary: This pilot study utilized the Linear Fit Method to compare the gait of stroke survivors with a healthy baseline in terms of walking speed. The results showed significant linear relationships between walking speed and the variations in the hemiparetic gait pattern. As walking speed increased, certain aspects of the gait pattern became more similar to the healthy comparison, while others remained different. These findings demonstrate how joint kinematics can be used to identify and quantify effective compensatory hemiparetic gait patterns.

Summary: In this study, a prediction model for the compressive strength of concrete with superplasticizers (SPs) was developed. The results showed that the addition of SPs can increase the compressive strength of concrete, reduce water content by 25 to 35 percent, and increase resistivity by 50 to 75 percent. It was also found that SPs have the second most impact on concrete's compressive strength after cement. Therefore, future studies should focus on designing concrete mixing plans and investigating the impact of water reduction on compressive strength.
