A novel energy dissipation device is proposed to protect structures against dynamic loads. conceptual model of the presented, describing fundamental components its operation. This has a linear elastic element and frictional damper. The equilibrium equations that lead relationship governs behavior are proposed. functional was built on 3D printer with PLA filament. Experimental trials were carrie...

This paper illustrates the results of an experimental campaign performed on a scale prototype base dissipator called Mini Tribological ROCKing Seismic Isolation Device. device allows smooth, controlled and damped rocking by means frictional layers viscous elastic springs, which aim at decoupling frequencies superstructure, dissipating energy during motion re-centering system once external actio...

In irrigation and drainage channels, vertical drops are generally used to transfer water from a higher elevation lower level. Downstream of these structures, measures taken prevent the destruction channel bed by flow reduce its destructive kinetic energy. this study, effect use steps grid dissipators on hydraulic characteristics regarding pattern, relative downstream depth, pool energy dissipat...

We consider an open quantum system with dissipation, described by a Lindblad Master equation (LME). For dissipation locally acting and sufficiently strong, separation of the relaxation time scales occurs, which, in terms eigenvalues Liouvillian, implies grouping latter distinct vertical stripes complex plane at positions determined dissipator. derive effective LME equations describing modes wit...

Abstract A container partially filled with loose plastic granules was attached to the shovel of snowboard suppress large-amplitude lateral vibrations by dissipating energy through non-conservative multi-granule interactions. custom laboratory stand allowed evaluate performance using a full-scale deck. The response system prototype granular dissipator measured for free initially deflected board ...
