Design of a Novel Auto-rotating Uav Platform for Underground Mine Cavity Surveying
The purpose of this paper is to investigate the potential for use of UAVs in underground mines and present a prototype design for a novel autorotating UAV platform for underground 3D data collection. The mining industry has recently shown increased interest in the use of unmanned aerial vehicles (UAVs) to assist in everyday operations [20, 11, 4]. Above ground, small UAVs are in some cases a mo...

متن کاملSome Land Surveying Problems
It is not probable that many of you would be interested in the academic presentation of a method for finding the area of a given polygon, as you each have a system of your own which is probably mathematically acceptable. However, I might take the liberty of citing to you pages 300 and 301 in Engineering Surveys, Elementary and Applied, by Rubey, Lommel, Todd, where you will find a good discussi...
متن کاملMine, mine, mine: information theory, infostation networks, and resource sharing
The Infostations wireless data network architecture features discontinuous coverage and ultra-high radio rates for burst transfers of information between base and mobile. It has been shown previously that the infostations architecture can greatly increase the capacity of wireless data systems at the expense of increased delivery delay. In this work we explicitly consider the multiple access iss...
