Structural, thermal, mechanical and physical performance of cellulose fibers based low-density polyethylene/recycled polyethylene terephthalate blend composites

Abstract Despite the increasing interest in recycled polymer composites and natural fiber reinforcement, relatively few studies have systematically examined low-density polyethylene (LDPE)/recycled polyethylene terephthalate (r-PET) blend systems reinforced with cellulose fibers...

CFD-Driven Passive Cooling and Renewable Retrofits for Nearly Net-Zero University Buildings in a Hot–Humid Climate

Achieving net-zero energy and zero-emission buildings is a critical pathway toward decarbonizing the built environment, particularly in cooling-dominated regions where operational energy demand remains exceptionally high. Existing university buildings in hot–humid climates face s...

Real-Time Leader-Follower UGV-UAV Cooperation: Experimental Validation and Control Analysis

Abstract This paper presents the experimental validation of a real-time leader–follower cooperative control architecture for a heterogeneous system composed of a differential-drive Unmanned Ground Vehicle (UGV) and a quadrotor Unmanned Aerial Vehicle (UAV). In the proposed framew...

Advanced MPPT Optimization for PV Water Pumping with Battery Storage and MPC-Driven BLDC Motor via Swarm and Evolutionary Algorithms

Photovoltaic (PV) pumping systems offer a sustainable alternative to diesel solutions, yet their nonlinearity, intermittent irradiation, and complex motor-pump dynamics challenge energy extraction and reliability. Currently, these systems predominantly rely on classical Maximum P...
