Corrugated multi-supersheets [PDF]
We explore the multi-superthreads and supersheets solutions of six-dimensional N=1 supergravity coupled to a tensor multiplet. The solutions carry D1-D5-P charges, but no Kaluza-Klein monopole. We lay down the formalism to construct multiple supersheets with arbitrary and independent profiles.

RAIL CORRUGATION EFFECT ON VIBROACOUSTIC PROPERTIES UNDER STOCK OPERATION
According to the papers of the German and French specialists, the rail corrugation stimulates increasing the rail sound radiation intensity. Besides, the consideration of the rail corrugation actually explains the high-frequency noise spectrum.

Dynamic characteristics and growth curve of rail corrugation at saturation stage
Rail corrugation, which causes the vibration and the noise, is a phenomenon in which roughness patterns of approximately regular wavelengths are formed on the rail running surface by trains running.

Influence of the meandering channel geometry on the thermo-hydraulic performances of an intensified heatexchanger/reactor [PDF]
In the global context of process intensification, heat exchanger/reactors are promising apparatuses to implement exothermic chemical syntheses. However, unlike heat exchange processes, the implementation of chemical syntheses requires to control the ...

Formation Mechanism of Metro Rail Corrugation Based on Wheel–Rail Stick–Slip Behaviors
Field investigation shows that most corrugations occur on the inner rail surface of curved tracks with a radius of less than 700 m. In order to explore the formation mechanism of metro corrugation, the relationship between wheel–rail stick–slip ...
