This paper is based on the main steel structural engineering project of Sanming Shaxian Airport Terminal. The lobby terminal building mainly composed box shaped components and BH beams. Purlins supports are made H-shaped or circular pipes other components. There 13 roof trusses located directly reinforced concrete columns in corridor, each truss connected by type joists. article introduces manu...

Extensions of singular spectrum analysis (SSA) for processing of non-rectangular images and time series with gaps are considered. A circular version is suggested, which allows application of the method to the data given on a circle or on a cylinder, e.g. cylindrical projection of a 3D ellipsoid. The constructed Shaped SSA method with planar or circular topology is able to produce low-rank appro...

Rhizobium leguminosarum NodD binds to the nod box of the inducible nod gene nodA as a V-shaped tetramer and bends the nod box. In this work, we show that the nod gene inducer naringenin decreased gel mobility of nod box DNA-NodD complexes by sharpening the NodD-induced DNA bend, which correlated with nodA transcription activation. NodD can induce different DNA bends when the distance between th...

I propose an analysis of either in either… or … sentences that relates to a broader generalization about the syntax all focus-sensitive operators. argue originates inside disjunction phrase, c-commanding leftmost contrastive focus. Then it is internally merged as sister phrase. Either copy may be pronounced. When appears higher than bare argument ellipsis has occurred second disjunct. This cons...

this paper aims to discuss the requirements of safe and smooth trajectory planning of transporter mobile robots to perform non-prehensile object manipulation task. in non-prehensile approach, the robot and the object must keep their grasp-less contact during manipulation task. to this end, dynamic grasp concept is employed for a box manipulation task and corresponding conditions are obtained an...

The energy absorbing capability is one of the most important aspects of crushing behavior of a structure subjected to axial impact. In this paper, a simple practical method is introduced to enhance the crushing behavior of this kind of structure. The axial impact of metallic energy absorbing thin-walled tubes with special shaped cross-section is simulated using LS-DYNA software. The effect of c...
