The in-pipe robots play significant role for applications like inspection of pipes or wearing of cables and materials, etc. The paper deals with motion analysis of in-pipe robot, whose actuator is based on shape memory effect. At first, the principle of motion and design solution of experimental in-pipe robot is introduced. Then the mathematical model is establish by means of Newton ́s mechanics...

The tree shape robot is mainly applied at the exhibition or performance. In order to take the eyes of the spectator, the moving function, reproducing the fast growth process of tree, is important function of the tree shape robot. This paper proposed the mechanism to reproduce growth process of tree shape robot which is used at the exhibition or performance. Proposed mechanism for growth process...

The influence of implanted Si, Mo and Ce vs. the as-received austenitic AISI 304 stainless steel has been studied after isothermal oxidation in air at 900 8C for 32 h. The oxide layer formed was characterised by means of conventional X-ray diffraction, scanning electron microscopyyenergy-dispersion spectroscopy and X-ray absorption spectroscopy (XAS) techniques. The projected ranges of the impl...

The murine Wand Steelloci encode the Kit receptor tyrosine kinase and its ligand, Steel factor, respectively. Loss of function mutations at either the Wor SI loci lead to a variety of pleiotropic developmental defects, including mast cell deficiency and severe macrocytic anemia. In addition to these loss-of-function mutations, gain-of-function mutations in ckit, leading to constitutive activati...

Advanced high strength steels (AHSS) are used for car body applications in the automotive industry to improve passenger safety, improve fuel efficiency and to lower harmful carbon emissions. Galvannealed AHSS are used to provide corrosion protection. AHSS are alloyed with several elements such as Mn, Si, Al, P, Mo, etc. to achieve better mechanical properties. However, the knowledge of the effe...
