Classification of Simulated Radio Signals Using Wide Residual Networks for Use in the Search for Extra-terrestrial Intelligence
We describe a new approach and algorithm for the detection of artificial signals and their classification in the search for extraterrestrial intelligence (SETI). The characteristics of radio signals observed during […]

The Epistemological Status of Astrobiology: A Problematic Case of Integration of Scientific Disciplines
Astrobiology is a scientific discipline that studies life in the Universe. We call it a discipline and not a science because some authors have cast doubts over its epistemological status […]
