Journal of Field Robotics, EarlyView.ABSTRACT This paper presents the first end‐to‐end framework that combines guidance, navigation, and centralized task allocation for multiple UAVs performing autonomous search‐and‐rescue (SAR) in GNSS‐denied indoor environments. A twin delayed deep deterministic policy gradient controller is trained with an artificial potential field (APF) reward that ...

BROADCAST TELEVISION: BROADCAST GEOGRAPHY?
European Journal of Geography, 2011 Television plays an important role in how the public both understands and takes an interest in geography. As geographers, if we are to maximise the opportunities provided by television to promote geography, we need to understand how it is developing in the 21st century. The first part of this paper examines some of the concepts currently applied to the
