Energy-saving, punctuality and smoothness are difficult to achieve in the operation of heavy haul train.This paper proposes a multi-objective method for speed curve optimization.Firstly, a quadratic programming optimization model is established, using train kinetic energy and train force as independent variables and several goals of energy conserva
funky chunky chocolate pretzels Abstract Using the second law of local thermodynamics and the first-order Palatini formalism, we formulate relativistic spin hydrodynamics for quantum field theories with Dirac fermions, such as QED and QCD, in a torsionful curved background.We work in a regime where spin density, which is assumed to relax much slowe
Dogfennel (Eupatorium capillifolium) is an aggressive native perennial that is found throughout much of the Southeast.Dogfennel is particularly troublesome in unimproved or overgrazed pastures where it adds to the decline of forage yield and bioglan deep sleep quality.Although generally considered to be only unsightly, the leaves contain low levels
