At altitudes below about 600 km, satellite drag is one of the most important and variable forces acting on a satellite. Neutral mass density predictions in upper atmosphere are therefore critical for (a) designing satellites; (b) performing adjustments to stay an intended orbit; (c) collision avoidance maneuver planning. Density have great deal uncertainty, including model biases misrepresentat...

A bottom-up approach has been adopted to identify a flavour model that agrees with present experimental measurements. The charged fermion mass hierarchies suggest only the top Yukawa term should be at renormalisable level. symmetry of Lagrangian including fermionic kinetic terms and is then combination $$U(2)$$ $$U(3)$$ factors. Lighter active neutrino masses quark lepton mixings arise consider...

The data-driven computing paradigm initially introduced by Kirchdoerfer & Ortiz (2016) is extended incorporating locally linear tangent spaces into the data set. These are constructed means of tensor voting method Mordohai Medioni (2010) which improves learning underlying structure a Tensor an instance-based machine technique accumulates votes from nearest neighbors to build up second-order ten...
