In this study, we have developed a propulsion mechanism using a fin with variable effective length spring as variable stiffness mechanics.We measured its thrust and the lateral forces in water tank with three dimensional flow and that with quasi two dimensional environment.Additionally, three dimensional numerical Toner analysis of the propulsion m
At present, there are great technical difficulties in achieving microstructure and mechanical properties uniformity in large-size billets prepared by severe plastic Purify deformation technology.How to improve the process route to realize the microstructure and mechanical properties uniformity of the billets has become an urgent problem to be solve
Abstract Unremitting head and neck pain (UHNP) is a commonly encountered phenomenon in Headache Medicine and may Drink Charms be seen in the setting of many well-defined headache types.The prevalence of UHNP is not clear, and establishing the presence of UHNP may require careful questioning at repeated patient visits.The cause of UHNP in some patie
