Aims: This study aims to analyze the accuracy of single- and double-diode models in predicting the electrical parameters of InGaP/InGaAs/Ge triple-junction solar cells as described in relevant patents under various operating conditions. Methods: This study obtained and analyzed experimental and theoretical values of the relevant electrical parameters of solar cells through a combination of experimental research and theoretic Read More

Background: A high percentage of renewable energy and a high percentage of power electronic devices are connected to the power system, which leads to the diversification and complexity of stochastic excitation, and the traditional single-excitation stochastic model is no longer applicable. Objective: The study aimed to solve the problem that the high proportion of renewable energy and the high proportion of power electro Read More

Background: The primary objective of this study is to assess the impact of welding conditions on the mechanical properties of friction stir-welded butt joints created from two distinct aluminium alloys, namely, AA6061 and AA7075. Friction stir welding (FSW), known for its innovation and low-energy solid-state bonding technique, was employed in this research. Methods: FSW experiments were carried out on both AA6061 and Read More

Temperature is crucial for battery pack durability and power. Folded fin and serpentine channel cooling methods are mostly used to cool the pack. However, fluid absorption during cooling can reduce capacity and cause downstream temperatures to be higher than upstream. Consistent cooling is vital to prevent temperature variation and increase battery pack lifespan. This work is concerned with the computational study of heat Read More

Background: The condition that vehicles are prone to skidding during emergency lane changing, an anti-rollover constraint is added to the trajectory planning. Methods: The evaluation index is constructed by the lateral load transfer rate LTR, so as to put forward a seventh-order polynomial trajectory planning method considering the anti-rollover. It improves the safety and stability of the planned trajectory of the i Read More

Background: Patient Transfer Apparatus (PTA), which has been reported by various relevant papers and patents, is widely used in the hospital. However, there are few corresponding transfer apparatuses for research and development in the nuclear magnetic resonance imaging (MRI) room because of the influence of a high magnetic field environment. It is desired to require the apparatus for the patient and the medical staf Read More
