Optimal low-thrust trajectories to asteroids through an algorithm based on differential dynamic programming [PDF]

open access: yes, 2009
In this paper an optimisation algorithm based on Differential Dynamic Programming is applied to the design of rendezvous and fly-by trajectories to near Earth objects. Differential dynamic programming is a successive approximation technique that computes

A time-frequency analysis approach for condition monitoring of a wind turbine gearbox under varying load conditions [PDF]

open access: yes, 2015
This paper deals with the condition monitoring of wind turbine gearboxes under varying operating conditions. Generally, gearbox systems include nonlinearities so a simplified nonlinear gear model is developed, on which the time–frequency analysis method ...

Quantitative conditions of rectifiability for varifolds [PDF]

open access: yes, 2014
46 pagesOur purpose is to state quantitative conditions ensuring the rectifiability of a $d$--varifold $V$ obtained as the limit of a sequence of $d$--varifolds $(V_i)_i$ which need not to be rectifiable. More specifically, we introduce a sequence $\left\

Woptic: optical conductivity with Wannier functions and adaptive k-mesh refinement

open access: yes, 2016
We present an algorithm for the adaptive tetrahedral integration over the Brillouin zone of crystalline materials, and apply it to compute the optical conductivity, dc conductivity, and thermopower.
