Testing Micro-Tubular SOFCs in Unmanned Air Vehicles (UAVs)

Small unmanned aerial vehicles (micro-UAVs, drones) in plant ecology1

PREMISE OF THE STUDY Low-elevation surveys with small aerial drones (micro-unmanned aerial vehicles [UAVs]) may be used for a wide variety of applications in plant ecology, including mapping vegetation over small- to medium-sized regions. We provide an overview of methods and procedures for conducting surveys and illustrate some of these applications. METHODS Aerial images were obtained by fl...

The Challenges of Flight-Testing Unmanned Air Vehicles

Unmanned Air Vehicles (UAVs) remain a developing technology of keen interest to the military as well as certain commercial enterprises (such as mining exploration companies), with over 200 UAV types in use throughout the world. UAVs present a difficult challenge for the T&E community as well, with present military UAV interest focussed on total autonomy to reduce operator skill requirements and...

A Situational Awareness Tool For Unmanned Aerial Vehicles (UAVs)

Optimizing Trajectories for Unmanned Aerial Vehicles (UAVs) Patrolling the Border

At first glance, most aspects of border protection activity look like classical examples of zero-sum games, in which the interests of the two sides are exactly opposite. This is how such situations are planned now: this is how border patrol agents are assigned to different segments of the border, this is how routes of coast guard ships are planned, etc. However, there is a big difference betwee...

Digital Counts of Maize Plants by Unmanned Aerial Vehicles (UAVs)

Precision phenotyping, especially the use of image analysis, allows researchers to gain information on plant properties and plant health. Aerial image detection with unmanned aerial vehicles (UAVs) provides new opportunities in precision farming and precision phenotyping. Precision farming has created a critical need for spatial data on plant density. The plant number reflects not only the fina...
