We propose a new system for vision-based mobile robot navigation in an unmodeled environment. Simple , unobtrusive artiicial landmarks are used as navigation and localization aids. The landmark patterns are designed so that they can be reliably detected in real-time in images taken with the robot's camera over a wide range of viewing conngurations. The code(More)
—The increasing development of large-scale offshore wind farms around the world has caused many new technical and economic challenges to emerge. The capital cost of the electrical network that supports a large offshore wind farm constitutes a significant proportion of the total cost of the wind farm. Thus, finding the optimal design of this electrical(More)
OBJECTIVES How a randomized controlled trial (RCT) is explained to patients is a key determinant of recruitment to that trial. This study developed and implemented a simple six-step model to fully inform patients and to support them in deciding whether to take part or not. STUDY DESIGN AND SETTING Ninety-two consultations with 60 new patients were(More)
In future long duration Mars exploration missions, network limitations and the lack of real-time communication capabilities will impact various aspects of space crew performance as well as behavioral health. Studies in ground-based analogs of Isolated and Confined Environments (ICE) such as Antarctica have identified sensory and social monotony as threats(More)
