Measuring the material's microhardness is generally easy and quick. However, since the operator reads the dimensions, i.e., the ends of the imprint formed in the material, the measurement result is greatly influenced by the operator's assessment. We present the research results in which three operators measured Vickers microhardness on the same im...

Metallic materials in granular packings show different electrical properties from their bulkcounterparts. In this paper, we investigate the temporal evolution of the electrical conductivity ofgranular metals. We use metallic beads arranged in different one-, two- and three-dimensionalensembles through which different constant currents are injected....
