Study of exponential stability of coupled wave systems via distributed stabilizer

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
Stabilization of the system of wave equations coupled in parallel with coupling distributed springs and viscous dampers are under investigation due to different boundary conditions and wave propagation speeds.

Control strategies for friction dampers: numerical assessment and experimental investigations.

open access: yesMATEC Web of Conferences, 2014
The use of friction dampers has been proposed in a wide variety of mechanical systems for which it is not possible to apply viscoelastic materials, fluid based dampers or others viscous dampers. An important example is the application of friction dampers

A Simplified Method for Predicting the Stability of Aerodynamically Excited Turbomachinery [PDF]

open access: yes, 1991
A method is presented for the quick and accurate prediction of the stability of aerodynamically excited turbomachinery using real eigenvalue/eigenvector data obtained from a rotordynamics model.

Design optimization of the JPL Phase B testbed [PDF]

open access: yes
Increasingly complex spacecraft will benefit from integrated design and optimization of structural, optical, and control subsystems. Integrated design optimization will allow designers to make tradeoffs in objectives and constraints across these ...

Attitude and Orbital Dynamics of a Variable-Geometry, Spinning Solar Sail in Earth Orbit [PDF]

open access: yes, 2017
At the ISSS 2013, a novel concept of variable-geometry solar sail was introduced: deployed in the shape of a three-dimensional quasi-rhombic pyramid (QRP), the sail exploited its shape and shift between center of mass and center of pressure to naturally ...

Mathematical Modeling and Simulation of Frame under Earthquake Excitation [PDF]

open access: yes, 2010
Earthquake excitation causes lots of damage. Modern structural protective systems can be used to reduce the damaging effect of destructive Earthquake forces. History of Structural design can be divided into three eras.
