The main goal of this work is to evaluate the feasibility to
calculate the technical debt (a traditional software quality approach) in
a model-driven context through the same tools used by software deve-
lopers at work. ...
[EN] This paper explores the relationship between interdisciplinarity and research pertaining to local issues. Using Colombian publications from 1991 until 2011 in the Web of Science, we investigate the relationship between ...
[EN] In this work, we investigate the path loss propagation of the vehicular-to-vehicular (V2V) channel when the vehicles are driving in the opposite direction. The investigation
is based on narrowband channel measurements ...
