The behaviour of beam-column joint plays an important role in the response of a steel moment resisting framed structure especially under seismic excitation. Semi rigid connections like bolted joints, allow better energy dissipation and provide good response under lateral loads. In this paper the ductility and energy dissipation characteristics of semi rigid bolted connections using double web a...

Rabbit muscle vesicles derived from sarcoplasmic reticulum were used as a material in studying networks of ryanodine receptors by cryo electron tomography. Three-dimensional analysis reveals the dynamical features of these networks. It was found that the connection angles were rotated along the transmembrane axis of ryanodine receptors. Majority of the connections was observed at domains 6/6 of...

The resonant frequency and sensitivity of an atomic force microscope (AFM) cantilever with assembled cantilever probe (ACP) have been analyzed and a closed-form expression for the sensitivity of vibration modes has been obtained. The proposed ACP comprises an inclined cantilever and extension, and a tip located at the free end of the extension, which makes the AFM capable of topography at sidew...

Let A be a square complex matrix. Let P be one of the following properties: (a) A is an EP matrix, (b) the column space of A is complementary to the column space of A Ã , and (c) the orthogonal complement of the column space of A is the column space of A Ã. We study the canonical angles between the column space of A and the column space of A Ã when A satisfies property P. Also, we research the ...

Both collinear factorization theorem 1 and kT factorization theorem 2,3 are the fundamental tools of perturbative QCD (PQCD), where kT denotes parton transverse momenta. In these theorems the amplitude for an exclusive process can be calculated as an expansion of αs(Q) and Λ/Q with Q being a large momentum transfer and Λ a small hadronic scale. Similarly, in the heavy quark limit mb → ∞, mb bei...

1 Motivation The compliant walking models are often used for reproducing characteristic gait dynamics [1]. However, since they require the touchdown angles to be chosen independently, there is a limited explanation for the foot placement selection in relation to the state of the body. In this study, it is hypothesized that the foot placement is indicated by progression of the center of pressure...

In this paper we explore, from an algorithmic point of view, the extent to which the facial angles and combinatorial structure of a convex polyhedron determine the polyhedron—in particular the edge lengths and dihedral angles of the polyhedron. Cauchy’s rigidity theorem of 1813 states that the dihedral angles are uniquely determined. Finding them is a significant algorithmic problem which we ex...

Phase error compensation within motion compensation techniques requires range cell migration corrected SAR data. The main contribution of this paper is providing a non-approximated range cell migration correction (RCMC) for processing highly squinted SAR data. Embedded in the conventional Omega-K processing, the approach consists of two coordinate transformations carried out in the 2D frequency...
