PR-MPC for NAO H21 Humanoid Robot: Capture Point Approach
2018 6th RSI International Conference on Robotics and Mechatronics (IcRoM), 2018The main target of this paper is to present a Push Recovery (PR) controller for the NAO H21 robot using Model Predictive Control (MPC) method. In order to compensate the applied push the hip strategy, the ankle strategy, the stepping strategy, and the upper-limb rotation strategy have been used.

H21 These Barbies were dermatologists
British Journal of DermatologyAbstract Greta Gerwig’s 2023 Barbie blockbuster provided an infectious reminder that women are capable of the success of their male counterparts, as well as emphasizing the impressiveness of female empowerment and leadership. Luckily, in dermatology, we have had this leadership from the beginning.

Wear, 1987
Abstract The effects of microstructure on the high temperature wear characteristics of 3Cr2W8V steel, the high temperature wear mechanisms and the features of the worn surface have been investigated by means of a resistance-heating high temperature wear-testing device of our own design. It has been shown that the primary parameters affecting the high

Materials Science and Engineering: A, 2013
Abstract An axisymmetric compression test was used to study the effect of hot deformation and double tempering on the microstructure and hardness of a H21 tool steel. The compression tests used a constant true strain rate of 0.01 s −1 , and were performed in the temperature range 1000–1100 °C after austenising at temperatures of either 1100 or 1250 ...

[Coagulometer H21: an automatic apparatus for coagulation study (author's transl)].
Nouvelle revue francaise d'hematologie, 1978We describe and present a new automatic device to measure the clotting time of a plasma plus reagent mixture by recording the time of transformation : solution to gel. The apparatus is able to perform 50 tests without manual help. Indeed it automatically carries out:--the dispatching of the tested plasma,--the dispatching of the various reagents,--the ...

Improvement of Friction and Wear Resistance for Ta or Ta+C Implanted H21 Steel
Chinese Physics Letters, 1997Ta and C ions extracted from a metal vapor vacuum arc ion source were implanted into H21 steel, with an implantation dose of 3 × 1017 cm-2, extraction acceleration 42 kV, and average ion beam flux about 40 μAcm-2. Rutherford backscattering spectrum was used to measure the surface composition after Ta or Ta+C implantation.
