For accurate motion compensation (MOCO) in airborne synthetic aperture radar (SAR) imaging, a high-precision inertial navigation system (INS) is required. However, an INS is not always precise enough or is sometimes not even included in airborne SAR systems. In this paper, a new, raw, data-based range-invariant motion compensation approach, which can effectively extract the displacements in the...

This work aims at improving instance retrieval with self-supervision. We find that fine-tuning using the recently developed self-supervised learning (SSL) methods, such as SimCLR and MoCo, fails to improve performance of retrieval. In this work, we identify learnt representations for should be invariant large variations in viewpoint background etc., whereas self-augmented positives applied by c...

Self-supervised representation learning has achieved promising results for downstream visual tasks in natural images. However, its use the medical domain, where there is an underlying anatomical structural similarity, remains underexplored. To address this shortcoming, we propose a self-supervised multi-task framework sequential 2D images, which explicitly aims to exploit structures via multipl...

A new multiple objective evolutionary algorithm is proposed for reliability optimization of series-parallel systems. This algorithm uses a genetic algorithm based on rank selection and elitist reinsertion and a modified constraint handling method. Because genetic algorithms are appropriate for high-dimensional stochastic problems with many nonlinearities or discontinuities, they are suited for ...

Las enfermedades hepáticas autoinmunes son caracterizadas por una respuesta inmune anormal dirigida a los hepatocitos o conductos biliares. Sus implicaciones se desencadenan en daño hepático crónico con fibrosis y cirrosis. La hepatitis autoinmune (HAI) caracteriza hepatocelular la cirrosis biliar primaria (CBP) colestasis. Los síndromes de sobreposición abarcan un subgrupo pacientes diagnostic...
