Rail roughness and rolling noise in tramways
Companies which manage railway networks have to cope continually with the problem of operating safety and maintenance intervention issues related to rail surface irregularities. A lot of experience has been gained in recent years in railway applications but the case of tramways is quite different; in this field there are no specific criteria to define any intervention on rail surface restoratio...
متن کاملHowe Correspondence and Springer Correspondence
Consider real reductive group G, as defined in [Wal88]. Let Π be an irreducible admissible representation of G with the distribution character ΘΠ, [Har51]. Denote by uΠ the lowest term in the asymptotic expansion of ΘΠ, [BV80]. This is a finite linear combination of Fourier transforms of nilpotent coadjoint orbits, uΠ = ∑ O cOμ̂O. As shown by Rossmann, [Ros95], the closure of the union of the ni...

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a by-product o f t he trichlorophenol (herbicide) production and is also produced through a variety of combustion processes. It appears that TCDD is a ubiquitous chemical, particularly in industrialised countries, and the liver is the target organ of its toxicity. The prominent hepatotoxic effect of TCDD is progressive centrilobular necrosis. Th...
متن کاملGround-borne vibrations, sounds and secondary airborne sounds from tramways: a psychoacoustic evaluation including health aspects
For decades, urban noise and vibration studies were mostly concerned with road traffic and trains. Tramway noise was rarely studied. Since the introduction of new types of tramways in the city of Graz strong complaints were brought up by local residents in certain areas. Typically, the annoyance by tramways results from a complex combination of sounds and vibration exposure depending on ground ...
متن کاملOpen-Curve Shape Correspondence Without Endpoint Correspondence
Shape correspondence is the foundation for accurate statistical shape analysis; this is usually accomplished by identifying a set of sparsely sampled and well-corresponded landmark points across a population of shape instances. However, most available shape correspondence methods can only effectively deal with complete-shape correspondence, where a one-to-one mapping is assumed between any two ...
