Application of the UAV-based inspection approach in engineering management In a groundbreaking study published in   Engineering , a collaborative team of researchers from Shanghai University and international experts have unveiled a cutting-edge approach to optimizing unmanned aerial vehicle (UAV) inspection routes and schedules for engineering projects. The research, led by Lu Zhen, Zhiyuan Yang, Gilbert Laporte, Wen Yi, and Tianyi Fan, introduces an innovative mixed-integer linear programming (MILP) model combined with a variable neighborhood search (VNS) algorithm, constructing a new approach in the field of engineering management. The rapid development and adoption of UAV technology have opened new horizons for various industries, particularly in engineering, where the need for efficient, safe, and cost-effective inspection methods is ever-present. Traditional inspection techniques, often manual and fraught with risks, fall short of addressing the complexities and dangers assoc...

  Recently,   Engineering   published the research work on sodium nitrate passivation as a novel insulation technology for soft magnetic composites developed by Prof. Mi Yan and Dr. Chen Wu’s team. Soft magnetic composites, which are fabricated based on metallic magnetic powders via insulation coating, binding, compaction, and annealing, serve as the key fundamental material in various fields including energy, transportation, aerospace, and national defense. Due to the low-electrical-resistivity nature of the soft magnetic alloys, it is challenging to control the eddy current loss, which has become a bottle-neck problem for high-frequency applications. For scientific research and industrial production, phosphorization technology is usually used to generate insulation coatings. However, the resultant phosphate coating tends to decompose above 600 ℃ and lose the insulation effect at elevated temperatures. It is of great significance to develop new insulation technology to f...
