MULTI-OBJECTIVE OPTIMISATION OF K-SHAPE NOTCH MULTI-WAY SPOOL VALVE USING CFD ANALYSIS, DISCHARGE AREA PARAMETER MODEL, AND NSGA-II ALGORITHM

Multi-objective optimisation of K-shape notch multi-way spool valve using CFD analysis, discharge area parameter model, and NSGA-II algorithm

Multi-way spool valves (MWSVs) with K-shape notches (KSNs) provide advantages such as improvement of the actuator speed control, micro-action, and response performance.However, the pressure drop (PD) associated with the energy consumption is larger of MWSVs under the high-pressure and large-flow condition.Meanwhile, extremely complex flow coefficie

Inflammatory cell infiltrates, hypoxia, vascularization, pentraxin 3 and osteoprotegerin in abdominal aortic aneurysms - A quantitative histological study.

Information about the tissue characteristics of abdominal aortic aneurysms (AAAs), some of which may be reflected in the serum, can help to elucidate AAA pathogenesis and identify new AAA biomarkers.This information would be beneficial not only for diagnostics and follow-up but also for potential therapeutic intervention.Therefore, the aim of our s
