Fractional-Order Control of a Micrometric Linear Axis
Published 2013-01-01“…This paper discusses the application of a particular fractional-order control scheme, the PDD1/2, to the position control of a micrometric linear axis. The PDD1/2 scheme derives from the classical PD scheme with the introduction of the half-derivative term. …”

Planetary formation and early phases
Published 2023-11-01“…In this review, we describe the structure and properties of such disks, and the various phenomenons that lead to the final product: a planetary system. First, micrometre dust settles and coagulates. Then, a complex interplay between the gas and centimetre aggregates leads to efficient phenomenons such as the streaming instability and the pebble accretion. …”

Mitigation of human factor in tomographic post processing of additive manufactured critical parts for aviation application
Published 2025-02-01“…Simultaneously to the development of AM fabrication, tomographic systems have also adapted to meet the needs of application-dependent inspection: from micro-focus and nano-focus systems for finding micrometre-sized discontinuities, to linear accelerators for inspecting large components built in high-density alloys, the current range of machinery allows for traversing and inspecting current production by filling the gap generated by the manufacturing paradigm shift. …”

The early development of a combined micro- and full-field X-ray fluorescence analysis system using white X-rays at PLS-II
Published 2025-01-01“…Micro-XRF (µ-XRF), the most basic conventional XRF technique, offers good spatial resolution through precise 2D scanning with a micrometre-sized X-ray source. Recently, synchrotron based XRF analysis platforms have achieved nano-XRF with highly focused X-rays using polycapillary optics or mirrors, leveraging the excellent coherence of synchrotron radiation. …”
