    CHART: Intelligent Crime Hotspot Detection and Real-Time Tracking Using Machine Learning

    Rashid Ahmad1, Asif Nawaz1,*, Ghulam Mustafa1, Tariq Ali1, Mehdi Tlija2, Mohammed A. El-Meligy3,4, Zohair Ahmed5

    CMC-Computers, Materials & Continua, Vol.81, No.3, pp. 4171-4194, 2024, DOI:10.32604/cmc.2024.056971 - 19 December 2024

    Abstract Crime hotspot detection is essential for law enforcement agencies to allocate resources effectively, predict potential criminal activities, and ensure public safety. Traditional methods of crime analysis often rely on manual, time-consuming processes that may overlook intricate patterns and correlations within the data. While some existing machine learning models have improved the efficiency and accuracy of crime prediction, they often face limitations such as overfitting, imbalanced datasets, and inadequate handling of spatiotemporal dynamics. This research proposes an advanced machine learning framework, CHART (Crime Hotspot Analysis and Real-time Tracking), designed to overcome these challenges. The proposed methodology… More >

    Research of Electric Cable Path Planning Based on Heuristic Optimization Algorithm in Mixed-Land Scenario

    Tianfeng Xu1, Tao Wang1, Chengming Ye2, Jing Zhang1, Peng Xi1, Yunhui Chen2, Gengwu Zhang3,*

    Energy Engineering, Vol.120, No.11, pp. 2629-2650, 2023, DOI:10.32604/ee.2023.027537 - 31 October 2023

    Abstract In order to improve the reliability of power supply, the sophisticated design of the structure of electric cable network has become an important issue for modern urban distribution networks. In this paper, an electric cable path planning model based on heuristic optimization algorithm considering mixed-land scenario is proposed. Firstly, based on different land samples, the kernel density estimation (KDE) and the analytic hierarchy process (AHP) are used to estimate the construction cost of each unit grid, in order to construct the objective function of comprehensive investment for electric cable loop network. Then, the ant colony More >
