Coronal magnetic flux ropes are generally considered to be the core structure of large-scale solar eruptions. Recent observations found that eruptions could initiated by a sequence "flux feeding," during which chromospheric fibrils rise upward from below, and merge with pre-existing prominence. Further theoretical study has confirmed feeding mechanism is efficient in causing eruption wrapped ba...

Different values of tension forces in the load-bearing ropes elevators, which push rope into grooves traction discs with different pressure, are cause uneven wear under operating conditions. Current technical standards EU stipulate that load suspended on be evenly distributed to all used, using one many construction designs for force equalizers system. The main subject and primary objective thi...

The Recursive Optimal per-Pixel Estimate (ROPE) algorithm allows the encoder to estimate the pixel-bypixel expected distortion of the decoded video sequence due to channel loss. The algorithm requires in input an estimate of the packet loss rate and the knowledge of the error concealment technique used at the decoder with no need to perform any comparison between original and decoded frames. Al...

In this study the macroscopic analysis proposed by Schapery has been applied to model the non-linear viscoelastic and viscoplastic behaviour of polyester fibres. First, a special non-contact extensometry method has been developed in order to measure the fibre response without affecting the behaviour of these extremely anisotropic fibres. An accelerated identification method has then been develo...

finite normalized tight frames are interesting because they provide decompositionsin applications and some physical interpretations. in this article,we give a recursive method for constructing them.

We develop a model of the fluctuation dynamo in which the magnetic field is confined to thin flux ropes advected by a multiscale model of turbulence. Magnetic dissipation occurs only via reconnection of the flux ropes. This model can be viewed as an implementation of the asymptotic limit R_{m}-->infinity for a continuous magnetic field, where magnetic dissipation is strongly localized to small ...
