We investigate wide-angle photoproduction of the ${\ensuremath{\eta}}^{\ensuremath{'}}$-meson within handbag approach to twist-3 accuracy. It turns out that, due gluon content ${\ensuremath{\eta}}^{\ensuremath{'}}$, this process is dominated by twist 2 in contrast with pion and $\ensuremath{\eta}$ photoproduction. Using presently available information on twist-2 distribution amplitudes $\ensure...

due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...

charles dickens was a voracious reader even in his childhood. his early reading of seventeenth- and eighteenth-century picaresque fiction greatly influenced his writing style. his first novel, the pickwick papers, is a tale of rogues and swindlers, adventures and quests, satire and comedy, and innocence and experience. oliver twist, dickens’ second novel, is a young boy’s progress through a cor...

A cylindrical rubber fiber subject to a twist will also elongate: manifestation of Poynting’s effect in large strain elasticity. Here, we construct an analogous treatment for active actuated via axisymmetric pattern spontaneous distortion. We start by constructing exact large-deformation solution the equations elasticity such imposed and stretch, which reveals warping twisting cross section abs...
