HappyFace as a monitoring tool for the ATLAS experiment
(2016-10-24)The importance of monitoring on HEP grid computing systems is growing due to a significant increase in their complexity. Computer scientists and administrators have been studying and building effective ways to gather ... -
Hard X-ray Waveguide Optics
(2005-11-18)The thesis is about the preparation of intense hard X-ray nanobeams focusing on the use of X-ray waveguides in resonant beam coupling and front coupling geometry. -
Harmonic analysis on 2-step stratified Lie groups without the Moore-Wolf condition
(2022-04-07)In this thesis we investigate harmonic analysis on a particular class of sub-Riemannian manifold, namely the 2-step stratified Lie groups $\mathbb{G}$, as well as its applications in partial differential equations. This ... -
