Calibration of an RF/Microwave Phase Noise Meter with a Photonic Delay Line

open access: yesPhotonics, 2022
The main advantage of phase noise meters with photonic (fiber) delay lines is that they do not require high-performance, low-noise reference oscillators.

Calibration of hydrological models for ungauged catchments by automatic clustering using a differential evolution algorithm: The Gorganrood river basin case study

open access: yesJournal of Hydroinformatics, 2023
The hydrological model calibration is a challenging task, especially in ungauged catchments. The regionalization calibration methods can be used to estimate the parameters of the model in ungauged sub-catchments.

Automatic Robot Calibration for the NAO [PDF]

open access: yes, 2015
In this paper, we present an automatic approach for the kinematic calibration of the humanoid robot NAO. The kinematic calibration has a deep impact on the performance of a robot playing soccer, which is walking and kicking, and therefore it is a crucial step prior to a match. So far, the existing calibration methods are time-consuming and error-prone,
