This study presents an automated method for objectively measuring rock heterogeneity via raw X-ray micro-computed tomography (micro-CT) images, thereby addressing the limitations of traditional methods, which are time-consuming, costly, and subjective. Unlike approaches that rely on image segmentation, proposed processes micro-CT images directly, identifying textural heterogeneity. The is partitioned into subvolumes, where attributes calculated each one, with entropy serving as a measure...

High-statistics $\pi^-\pi^-$ and $\pi^+\pi^+$ femtoscopy data are presented for Au+Au collisions at $\sqrt{s_\mathrm{NN}}=2.4$ GeV, measured with HADES SIS18/GSI. The experimental correlation functions allow the determination of space-time extent corresponding emission sources via a comparison to models. source, parametrized as three-dimensional Gaussian distribution, is studied in dependence on pair transverse momentum, azimuthal angle respect reaction plane, collision centrality beam...

This work presents the analysis of performance RPC ToF wall HADES, located at GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt. The behavior detector is studied in Au+Au collisions 1.23 AGeV. A main characteristic that all active areas were designed to be electrically shielded order operate high occupancies chambers. Here we show achieved regarding efficiency and timing capabilities different this special design after applied offline corrections data. Also stability intrinsic time...

One of the goals COMPASS experiment is determination gluon polarisation, ΔG/G, for a deep understanding spin structure nucleon. The polarisation can be measured via Photon-Gluon-Fusion (PGF) process. methods to identify this process selecting high pT hadron pairs in final state. data used analysis were collected by during years 2002 2006, using 160 GeV naturally polarised positive muon beam impinging on nucleon target. A new result ΔG/G from events with Q2 > 1 (GeV/c)2 presented. This has...
