This numerical investigation examines the performance and exergy analysis of parabolic trough solar collectors, focusing on the substitution of the conventional circular absorber with a rhombus-shaped absorber. By evaluating the thermal and fluid dynamics properties, this study aims to identify improvements in overall system performance and efficiency. This numerical study conducts a comprehensive thermal analysis of parabolic trough solar collectors by comparing a rhombus-shaped absorber with a conventional circular absorber.

The circle of Willis (CoW) is a circular arrangement of arteries in the human brain, exhibiting significant anatomical variability. The CoW is extensively studied in relation to neurovascular pathologies, with certain anatomical variants previously linked to ischemic stroke and intracranial aneurysms. In an individual CoW, arteries might be absent (aplasia) or underdeveloped (hypoplasia, diameter < 1 mm).

To address the problems of the labeling curved surfaces vegetable with long label, such as the label wrinkled and the easy detachment, a cam-elliptical gear combined labeling mechanism with an improved hypocycloid trajectory is proposed. Provide the process of the mechanism, and establish a kinematic model of the mechanism. In order to improve the motion performances of the cam-elliptical gear combined labeling mechanism and avoid labels damage, the NSGA-II algorithm is used to optimize the parameters of the mechanism, resulting in 80 sets of Pareto solutions.
