This paper presents an application of ultrasonic signal processing to find parameters related with physical properties of archaeological ceramic pieces and consolidation products used in their restoration. Pieces consisted of ceramic fragments from Bronze, Iberian, Roman and Middle ages. Ultrasonic signals measured from the pieces were processed to derive(More)
This paper presents an application of the ultrasounds that pursue to find parameters related with physical characteristics of archaeological ceramic materials and the evaluation of the consolidation materials used in their restoration process. The studied archaeological materials were from the Requena's archaeological museum at the East of Spain and consist(More)
Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E ≥ 6×10 19 eV by analyzing cosmic rays with energies above E ≥ 5×10 18 eV arriving within an angular separation of approximately 15 •. We characterize the(More)
