Abstract Plastic materials are extensively utilized in various aspects of daily life. However, the substantial amount plastic waste generated can cause significant global environmental issues without efficient management practices. To address this problem, utilization plastics high-value applications such as highway construction through hot mix asphalt (HMA) has been deemed ideal. Polyethylene terephthalate (PET), low-density polyethylene (LDPE), and high-density (HDPE) three most prevalent...
This study aimed to evaluate 2D magnetic flux leakage (MFL) signals (Bx, By) in D19-size reinforcing steel with several defect conditions. The data were collected from the defected and new specimens using an economically designed test setup incorporating permanent magnets. A two-dimensional finite element model was numerically simulated COMSOL Multiphysics validate experimental tests. Based on MFL By), this also intended improve ability analyze features such as width, depth, area. Both...
This paper reported a pioneering 5G multiband microstrip line fed patch antenna for IoT, wireless power transfer (WPT) and data transmission. The proposed is accomplished using triple L-arms responsible the response. A diamond-shaped ground slot added to control increase bandwidth of resonant frequency. designed resonate at 10, 13, 17 26 GHz with 10 dB impedance bandwidths 0.67, 0.8, 2.45 4.3 respectively. fabricated technology total area 16.5x16.5 mm2. has sufficient realized gain 4.95,...
