A set of efficient algorithmic solutions suitable to the fully parallel hardware implementation short-length circular convolution cores is proposed. The advantage presented algorithms that they require significantly fewer multiplications as compared naive method implementing this operation. During synthesis algorithms, matrix notation cyclic operation was used, which made it possible represent ...

Slender structures with circular cylindrical cross-sections are very common in civil engineering, industrial equipment and bridge engineering. Such long cylinders subjected to wind columns, piles, cables, chimney, pylons others. On an instability called dry galloping has been recently theorized be linked unpredictable jump state occurring once the boundary layers of cylinder changes from lamina...

Context. Rotation Measure synthesis of the Westerbork Synthesis Radio Telescope (WSRT) observations at λ ∼ 2 m of the FAN region at l=137◦, b=+7◦ shows the morphology of structures in the ionized interstellar medium. Aims. We interpret the diffuse polarized synchrotron emission in terms of coherent structures in the interstellar medium and the properties of the interstellar magnetic field. Meth...

Exact solutions to the problem of the Newtonian gravitational interaction of N material points moving around N 2 concentric circular orbits are considered. Each circular orbit contains N 3 axisymmetrically located bodies having identical masses. The structure as a whole rotates around its symmetry axis. Such structures are identical to the homographic-dynamics configurations, or planar central ...

viroids are smallest, single-stranded, circular, highly structured plant pathogenic rnas that do not code for any protein. viroids belong to two families, the avsunviroidae and the pospiviroidae. members of the pospiviroidae family adopt a rod-like secondary structure. in this study the most stable secondary structures of citrus viroid variants that reported from fars province were drawn. the m...

In this paper, we derive the generating function of RNA structures with pseudoknots. We enumerate all k-noncrossing RNA pseudoknot structures categorized by their maximal sets of mutually intersecting arcs. In addition, we enumerate pseudoknot structures over circular RNA. For 3-noncrossing RNA structures and RNA secondary structures we present a novel 4-term recursion formula and a 2-term recu...
