Operating point assignment of a linear motor driven vehicle using multiobjective optimization methods

A test track of 530 m length for linear motor driven railway vehicles in scale of 1:2.5 was built at the University of Paderborn in 2002. A doubly-fed long stator linear motor does not only drive the vehicles, but offers the opportunity of a contactless energy transmission into the vehicle’s on-board supply system, too. In this pape, the motion control structure is presented comprising an operating point assignment of the linear motor optimized by a multiobjective optimization method

Slopes of Overconvergent Hilbert Modular Forms

We give an explicit description of the matrix associated to the Up operator acting on spaces of overconvergent Hilbert modular forms over totally real fields. Using this, we compute slopes for weights in the center and near the boundary of weight space for certain real quadratic fields. Near the boundary of weight space we see that the slopes do not appear to be given by finite unions of arithmetic progressions but instead can be produced by a simple recipe from which we make a conjecture on the structure of slopes. We also prove a lower bound on the Newton polygon of the Up
