TECCIENCIA is a bi-annual journal concerned with the different problems that science and engineering are facing nowadays. This journal was created in 2006 as a tool to share some of these results with an increasing audience that is interested in finding out about the advances in engineering in Colombia. We are currently moving towards reaching a broader, international audience in order to make a deeper contribution to our scientific understanding of the world. This journal is intended as a medium for publishing highly innovative, high-impact results. Our scope is broad and includes many topics of increasing interest regarding environmental, mechanical, electronics, biomedical, process, electric, software, energy engineering and applied sciences.
