Quasi-static stationary-periodic model of percussive deep drilling

, 2005
Copyright @ 2005 Patron EditoreIn the percussively deep drilling, the rock is modeled by an infinite elastic medium with a semi-infinite cylindrical bore-hole having a curvilinear bottom.

The Italian “Moving Boundaries”

, 2020
This paper illustrates the main characteristics of the border lines separating the current territory of the Italian Republic from the mainland European states; it focuses on the operations to maintain these borders; clarifies the meaning and limits of the so-called "mobile border", introduced into contemporary vocabulary following the first melting ...

Moving-boundary approaches for American security valuation

, 2008
This dissertation is concerned with the classical problem of pricing an American option written on a single underlying asset. Even under the simple Black-Scholes model, the pricing of the option is non-trivial.

MD boundary conditions for pressure gradient flows : nano-mixing and nano-droplet deformation in extensional flows

, 2010
We present new algorithms for simulating pressure gradient flows in molecular dynamics (MD) simulations. Nano-channel inlet and outlet non-periodic boundary conditions are implemented using hydrodynamic state reservoirs and flux boundary models at ...

Optimization and Control in Free and Moving Boundary Fluid-Structure Interactions

, 2018
We consider optimization and optimal control problems subject to free and moving boundary nonlinear fluid-elasticity interactions. As the coupled fluid-structure state is the solution of a system of partial differential equations that are coupled through
