Reliable shapelet image analysis [PDF]
Astronomy & Astrophysics, 2006 Aims: We discuss the applicability and reliability of the shapelet technique for scientific image analysis. Methods: We quantify the effects of non-orthogonality of sampled shapelet basis functions and misestimation of shapelet parameters. We perform the shapelet decomposition on artificial galaxy images with underlying shapelet models and galaxy ...

Gravity-Based Kinetostatic Modeling of Parallel Manipulators Using Screw Theory
Chinese Journal of Mechanical Engineering, 2023 The pose accuracy of parallel manipulators (PMs) is a key index to measure their performance. Establishing the gravity-based kinetostatic model of a parallel robot provides an important basis for its error composition and accuracy improvement.
