We examine the nonlinear response of two planar pendula under external and kinematic excitations, which are very relevant as paradigmatic models in nonlinear dynamics. These pendula act under the action of an additional constant torque, and are subjected...

The traditional method for calculating the buffeting response of long-span bridges follows the strip assumption, and is carried out by identifying aerodynamic parameters through sectional model force or pressure measurement wind tunnel tests. However, th...

Water scarcity is one of the major concerns of this century. The photocatalysis through TiO2 can be suitable for improving liquid wastewater treatment. However, TiO2 is used as a powder (nanoparticles), which is a drawback for full-scale applications. To...

Helicopters are widely used for air transportation and aerial work with cargo on external cables, one of the most challenging and dangerous uses. The main reason for the flight complication is the change in the controllability characteristics of the heli...
