One of the most important components an aircraft is landing gear. In today`s modern gears, mostly oleo-pneumatic shock struts are used. Analytically, gear can be modeled as a mass-spring-damper system. The model used in study included such strut, tire and wheel. Furthermore, tapered metering pin was added to order control area orifice by which hydraulic oil flows during act impact force. Landin...

Lyα absorber correlations contain information about the underlying density distribution associated with a particular class of absorbers. As such, they provide an opportunity to independently measure the “bias” of the Lyman alpha forest, i.e. the relationship between H I column density and underlying dark matter density. In these proceedings we use hydrodynamic simulations to investigate whether...
