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 Americano Cup tank with three dimensional flow and that with quasi two dimensional environment.Additionally, three dimensional numerical analysis of the prop
Many common discriminators used for code tracking of global navigation Shoes - Sandals - Mens satellite system (GNSS) signals are ratios of quadratic forms of the correlation outputs.Here we derive a general expression for the gain of this type of discriminator and show that it depends on the effective copyright-to-noise ratio.We then evaluate this
Susac syndrome is a rare, probably immune-mediated endotheliopathy presenting with encephalopathy, sensorineural hearing loss and retinal arterial occlusions.A 33-year-old female with Susac syndrome was worsening despite high-dose steroids so a brain biopsy was performed which suggested a possible fungal infection.Treatment with amphotericin B resu
Managing pests in carrot production is challenging.Endophytic microbes have been demonstrated to improve the health and productivity of many crops, but factors affecting endophyte dynamics in carrot is still not well understood.The goal of this study was to determine how crop management system and carrot genotype interact to affect the composition
Over the past decades, the Southern Governments have sought to make innovation a key issue in their policy agenda as a catalyst toward sustainable development.Many southern countries realised that innovation with the use of science and technology had a vast potential in the economic transformation of a nation and as means to economic growth.In form
