On attitude representations for optimization-based Bayesian smoothing

This paper presents a study of the behavior of seven different attitude representations in a batchwise orientation smoothing problem. The representations include the well-known unit quaternions and rotation vectors(/axis-angle), as well as modified Rodrigues parameters (MRPs). We consider error states as well as direct orientation formulations...

JAY: Kitting as optimization tool of aircraft maintenance

Kitting as (LEAN) method in handling and supplying material and tools is not used in the aircraft maintenance process of KLM. That was one of the researchers first findings when starting this study for KLM Royal Dutch airlines. Kitting is the gathering of components and parts needed for the manufacture of a particular assembly or product....
