The angular correlation function of partons in a jet as derived from perturbative QCD is nonanalytic at a critical angle which separates a multiparticle regime with scaling properties from a regime with few particles near the hadronisation scale. Some phenomenological consequences are discussed. MPI-Ph/95-98 TPJU-17/95 November, 1995 hep-ph/9511457 1

Collapse by buckling a quite common phenomenon in sheets under pressure. When these structures caused by defects such as corrosion and cracks the time of the occurrence of this phenomenon is sensitive and critical load to be significantly reduced. Therefore, in this article sheet of aluminum Al 1200 by cracks in a part of the sheet will be considered. Left angle on the critical buckling load ef...

We present a concept that enables the determination of complex refractive index attenuating media from two critical angles, measured sequentially at interfaces between single sample and different prisms. The proposed method is general in it applies with s p polarisation states, thus suited for characterisation isotropic as well anisotropic media. Uncertainty analysis indicates relative error re...

Visual estimation of object stability is an ecologically important judgment that allows observers to predict the physical behavior of objects. A natural method that has been used in previous work to measure perceived object stability is the estimation of perceived “critical angle” – the angle at which an object appears equally likely to fall over versus return to its upright stable position. Fo...
