Train Energy-efficient Operation with Stochastic Resistance Coefficient

Train energy-efficient operation problem applies the optimal control theory to optimize the speed profile between successive stations such that the tracking energy is minimized. Traditional studies show that the optimal speed profile consists of four phases including maximum acceleration, cruising, coasting and maximum braking. Based on the assumption that the resistance coefficients are random...

To train or not to train.

R ecently there’s been a push among some of our clients to start bringing 3d imaging systems in-house. In the majority of cases the client wants my company to provide some form of training to help them get off on the right foot. Although we are in the consulting business, training is a different animal. We’ve worked for years, continuously refining our processes and tools, investing in R&D and ...

Howe 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...
