Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 11,   Pages 1477-1491 doi: 10.1631/FITEE.2000632

Abstract: The use of unmanned aerial vehicles (UAVs) is becoming more commonplace in tasks, but UAV search planning can be very complex due to limited response time, large search area, and multiple candidate search modes. In this paper, we present a UAV search planning problem where the search area is divided into a set of subareas and each subarea has a prior probability that the target is present in it. The problem aims to determine the search sequence of the subareas and the search mode for each subarea to maximize the probability of finding the target. We propose an adaptive that combines a genetic algorithm with a set of local search procedures and dynamically determines which procedure to apply based on the past performance of the procedures measured in fitness improvement and diversity improvement during problem-solving. Computational experiments show that the proposed algorithm exhibits competitive performance compared to a set of state-of-the-art global search heuristics, non-adaptive s, and adaptive s on a wide set of problem instances.

Strategic Study of CAE 2017, Volume 19, Issue 6,   Pages 92-99 doi: 10.15302/J-SSCAE-2017.06.014

Abstract:

Urban underground space has become the fastest growing area in global engineering construction and commercial operation. The scale and level of China's urban underground engineering have reached considerably advanced, but ensuing security accidents in urban underground spaces have also significantly increased, and the necessary security monitoring and emergency rescue measures are seriously lacking. This paper focuses on the security issues pertaining to terrorism, explosions, and nuclear biological or chemical attacks in urban underground spaces and analyses the challenges faced by infrared imaging technology when implemented in disaster monitoring and emergency search and rescue. The key technologies and applications presented include shortwave infrared imaging, multi-scale infrared imaging preprocessing, adaptive image enhancement, adaptive infrared environment imaging, and disaster location and alarm. This paper discusses the applications of infrared imaging technology in underground space emergencies such as fires. The research presented here can provide references for security legislation and the strategic planning of urban underground space in China.
