this paper describe the three dimensional finite element modeling and buckling analysis ofconventional pallet racking system with semi rigid connection. in this study threedimensional models of conventional pallet racking system were prepared using the finiteelement program ansys and finite element analysis carried out on conventional pallet rackswith the 18 types of column sections developed a...

Enterprise informatization is a large system including: input, output, feedback, operation inside, executive action and incentive measures. Inner-enterprise can be seemed as an artificially social organization unit composing of various agents in a rigid formation. This paper mainly proposes an enterprise informatization associated with rigid formation theory of multi-agent. The connection betwe...

In the two-dimensional discrete element modeling of displacement of sedimentary layers caused by faulting within the basement, we attempted to move a rigid basement as if it were an elastic basement by controlling its motion through application of dislocation solutions. An advantage of our modeling procedure is that we can discuss displacement fields of sedimentary layers in connection with fau...

The research subject is the rotational stiffness of modular building metal frame nodal connection. connections has a significant impact on results calculating load-bearing building. It known that absolutely rigid exist only in theory. In practice, each connection finite stiffness, as evidenced by numerous studies researchers. When designing real objects, certain design should be carried out. As...

We present the computation of lagrangian-based flow characterization measures for time-dependent, deformable-wall, finite-element blood flow simulations. Applicability of the algorithm is demonstrated in a fluid-structure interaction simulation of blood flow through a total cavopulmonary connection (Fontan procedure), and results are compared with a rigid-vessel simulation. Specifically, we rep...

We describe a simple modification to a rigid endoscope so as to provide both high-quality conventional and confocal images of reasonably accessible regions of the body. This versatile system uses a structured illumination approach together with a conventional incoherent illumination source. Images taken in fluorescence are presented using this combined conventional and confocal endoscope.

Hybrid moment frame come together with reinforced concrete columns with structural steel beams (RCS). This Composite system provides several key advantages over current steel or concrete moment resisting frame. Past studies have shown this system to be efficient in both design and building stage while able to keep sufficient strength and necessary ductility in seismic zone.Although past researc...

Weakly convex polyhedra which are star-shaped with respect to one of their vertices are infinitesimally rigid. This is a partial answer to the question whether every decomposable weakly convex polyhedron is infinitesimally rigid. The proof uses a recent result of Izmestiev on the geometry of convex caps.

We point out an interesting connection between fluid dynamics and minimal surface theory: When gluing helicoids into a surface, the limit positions of correspond to ‘vortex crystal’, equilibrium vortices in two-dimensional that move together as rigid body. While vortex crystals have been studied for almost 150 years, construction surfaces is relatively new. As consequence connection, we obtain ...

OBJECTIVE Tooth/implant supported fixed prostheses may present biomechanical design problems, as the implant is rigidly anchored within the alveolus, whereas the tooth is attached by the periodontal ligament to the bone allowing movement. Many clinicians prefer tooth/implant supported fixed prosthesis designs with rigid connectors. However, there are some doubts about the effect of attachment p...
