In the next article entitled "A Cautionary Tale for Machine Learning Design: Why We Still Need Human-Assisted Big Data Analysis", the authors present a study with the main goal to increase the accuracy of a Supervised Machine Learning (ML) system in predicting when a water meter would malfunction/need disassembly based on a history of water consumption measurements. The fourth article entitled "Detecting vehicles' relative position on two-lane highways through a smartphone-based video overtaking aid application" presents a smartphone-based real-time video overtaking architecture for vehicular networks. In the presented scenario, ahead vehicles stream a video flow to the vehicle behind aiding the overtaking maneuver. [Extracted from the article]
