Abstract In order to study the stability performance of three-limbed steel tube latticed column, finite element numerical analysis method based on structural theory is adopted. Firstly, linear column without diagonal lacing bar carried out, and calculation elastic buckling load considering influence shear deformation obtained. Then, elastoplastic with are out. The studied when only global initi...

-Tall latticed steel towers are being pursued for the purpose of microwave transmission, T.V. transmission etc. Antennas are fixed at the top of the tower for transmission. The height of the towers may range from 50m to 250m. The structural form consists of latticed steel work, suitable bracing and suitable foundation for the tower legs. Usually bolted connections are provided for the joints. M...

We report in this work a practical design of pentamode acoustic cloak with microstructure. The proposed cloak is assembled by pentamode lattice made of a single-phase solid material. The function of rerouting acoustic wave round an obstacle has been demonstrated numerically. It is also revealed that shear related resonance due to weak shear resistance in practical pentamode lattices punctures b...

A finite distributive latticeD can be representedas the congruence lattice, ConL, of a finite lattice L. We shall discuss the combinatorial aspects of such—and related—representations, specifically, optimal size, breadth, and degree of symmetry.

gilles fauconnier and mark turner have considered the issue of conceptual metaphor as a special case of more general and comprehensive matter. this vast matter is the analysis of mind system mechanism when it exposes to conceptual domains. to describe such a process, fauconnier and turner use the term of mental or conceptual space. they believe that in order to understand much of human thought ...

Recombinant clathrin protein fragments form assemblies that template gold nanocrystals in an array across the latticed surface. The nanocrystals exhibit unusual anisotropic morphologies with long range ordering, both of which are dependent upon the presence of a hexahistidine tag on the clathrin heavy chain fragments.

Tom George lias an odd kind of picture gallery. All the houses in his street have lean-to pantries, with tiny windows, the upper half glass, the lower latticed wood. It is traditional to keep the family egg-cups on the ledge formed by the wooden bottom of the glass section. Every variety of egg-cup is here displayed?white, red, and blue china, and metal. Occasionally other small, gay articles a...
