Composition, change and complexity have attracted ev- eryone’s attention towards Self-Adaptive systems. These systems, inspired by the human body, are capable of adapting to changes in the inner and outer environment. The main objective of this study is to achieve a more con- venient availability for e-banking services in the payment switch, using self-healing systems and focusing on the failur...

Abstract: the article provides a calculation justification of proposed railway structure on reinforced concrete sleeper-free base, for which an analysis existing methodology calculating track strength is carried out, according to dynamic loads acting from rolling stock are determined. The applied sleeper-less structures and results measurements emerging stresses in substructure, measured depth ...

The purpose of the research was to study condition prestressed monoblock concrete sleeper (PMCS) under dynamic loading experimentally and through site investigation. From this research, value deflection base on acceleration sleepers have been obtained. This showed possible correlation relation PCS located a railway track. includes experimentation process which experimental investigations for (P...

The problem of damping the noise on track, arising from movement train, is solved sufficiently but it simple, if rail with spacers laid inside longitudinally located band sleeper-mechanism. result a layered thread, consisting belts: tape elastic three sides, tie-mechanism and ballast layer. unity layers carried out due to their own mass. This static track without external load. Rail compression...

In Krylov's analytical prediction model, the free field vibration response during the passage of a train is written as the superposition of the effect of all sleeper forces, using Lamb's approximate solution for the Green's function of a halfspace. When this formulation is extended with the Green's functions of a layered soil, considerable computational effort is required if these Green's funct...

In a previous communication, Sheets et al. (1954) have shown that three phenol-resistant organisms, a sporeforming rod, a coccus and a short rod, belonging to the genera Bacillus, Micrococcus and Pseudomonas respectively, were isolated from a trickling filter, operated continuously at 54 C for the treatment of phenolic wastes. The Pseudomonas-like rod predominated over the other two types. A pu...

We propose a novel two state and all-optical controllable switch using DIT, Kerr effect and interaction between quantum dots (QD) and quantum electrodynamics cavity (CQED). The two state and all-optical controllable switch is coupled to photonic waveguide from a rapid nonlinear environment (photonic crystal) and CQED. We consider the nano-crystal are doped to crystal photonic cavity as a 4-leve...
