Relationships between middle childhood outdoor experiences and an adult individual's knowledge of the environment
During the last several decades, the nature of childhood has changed. There is not much nature in it anymore. Numerous studies in environmental education, environmental psychology, and conservation psychology show that the time children spend outdoors encourages healthy physical development, …

Robot Team Formation Control Using Communication "Throughput Approach"
<p>In this thesis, we consider a team of robots forming a mobile robot network cooperating to accomplish a mission in an unknown but structured environment. The team has no a-priori knowledge of the environment. Robots have limited memory storage capabilities, not enough to map the environment. …

Location Estimation of Obstacles for an Autonomous Surface Vehicle
As the mission field for autonomous vehicles expands into a larger variety of territories, the development of autonomous surface vehicles (ASVs) becomes increasingly important. ASVs have the potential to travel for long periods of time in areas that cannot be reached by aerial, ground, or …

The Environment Constrains Successful Search Strategies in Natural Distributed Systems
… that use distributed search algorithms and tests the hypothesis that the searchers' environment is a key constraint on an optimal algorithm. Natural instances of distributed autonomous systems of simple components exist in both biology and social systems. These systems have been honed through eons …

Willingness to pay for eco-labelled forest products in Northern Ireland
Wooded areas provide us with a variety of market and non-market benefits, but rising deforestation, contributed to by pressures on landowners to clear forested areas to use as pasture and arable land, may cause the irrevocable loss of these benefits. To combat this, there is a need to encourage …

Tactile mapping of harsh, constrained environments, with an application to oil wells
… develops a practical approach to explore rough environments when time is critical. The harsh environmental conditions prevent the use of range, force/torque or tactile sensors. A representative case is the mapping of oil wells. In these conditions, tactile exploration is appealing. In this work, …

Query-driven adaptive sampling
Automated information gathering allows exploration of environments where data is limited and gathering observations introduces risk, such as underwater and planetary exploration. Typically, exploration has been performed in service of a query, with a unique algorithm developed for each mission. Yet …

Autonomous navigation in unknown environments using machine learning
In this thesis, we explore the problem of high-speed autonomous navigation for a dynamic mobile robot in unknown environments. Our objective is to navigate from start to goal in minimum time, given no prior knowledge of the map, nor any explicit knowledge of the environment distribution. Faced with …
