1. Developing Primary Controls for Multiple CE-Machines in a Teleoperation's Environment
Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknikSammanfattning : Background: An intermediate step towards fully autonomous construction equipment is “assisted tele-remote operation”. These sorts of operations imply that an operator remotely supports machines that has encountered a situation that autonomous systems onboard the construction machines (CM) cannot solve. LÄS MER
2. Comparison of tree cavity abundance and characteristics in managed and unmanaged Swedish boreal forest
Magister-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Tree cavities are major components of the forest ecosystem worldwide as they are required substrate for a large number of species (including nesting and roosting birds, mammals, fungi, and insects). The present study aimed to provide new knowledge on cavity density and cavity tree characteristics in the Swedish boreal zone where only little information exists on this subject. LÄS MER
3. Effects of tree retention on cavity-nesting birds in northern Sweden
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Tree cavities are of high ecological value because they influence the abundance, diversity, and conservation of many terrestrial animals in forests worldwide. However, due to forest management practices, cavity-users are under a serious threat in many forest ecosystems. LÄS MER
