We analyze the capability of different types of perturbations associated with usual environment energy fluctuations of the solarcorona to excite slow and sausage modes in solar flaring loops.Methods. We performed numerical ...

Aims. We analyse the capability of different types of perturbations associated with usual environment energy fluctuations of the solar corona to excite slow and sausage modes in solar flaring loops. Methods. We performed ...

We present measurements of the non-linear oscillations of a portal frame foundation for a non ideal motor. We consider a three-time redundant structure with two columns, clamped in their bases and a horizontal beam. An ...

The excited state dynamics of Zn2+, Fe3+, and Mn3+ meso-tetra(sulfonatophenyl) porphyrin complexes were investigated with a Z-scan technique at 532 nm using 70 ps and 120 fs single pulses and 200 ns pulse trains of a ...

This work is concerned with damages of trash-racks of hydroelectric power plants excited by the flow passing around them, and with the analysis of virtual mass effect on the natural frequencies and mode shapes of the ...

We show that a scalar excited state with large occupation numbers during inflation leads to an enhancement of tensor modes and a characteristic pattern of order-one oscillations in the associated stochastic gravitational ...
