An improved dynamic window approach algorithm for dynamic obstacle avoidance in mobile robot formation
Cao, Yanjie; Norzalilah Mohamad Nor - In: Decision analytics journal 11 (2024), pp. 1-14
Dynamic Window Approach (DWA) algorithm is a commonly used choice in dynamic obstacle avoidance. However, the traditional DWA algorithm evaluation function is poorly adapted to dynamic obstacle avoidance and has defects in efficiency and safety. In this paper, we consider the speed and heading...

A novel efficient energy optimization in smart urban buildings based on optimal demand side management
Alhasnawi, Bilal Naji; Jasim, Basil H.; Alhasnawi, … - In: Energy strategy reviews 54 (2024), pp. 1-22
Increasing electrical energy consumption during peak hours leads to increased electrical energy losses and the spread of environmental pollution. For this reason, demand-side management programs have been introduced to reduce consumption during peak hours. This study proposes an efficient energy...
