Scaling behavior in land markets [PDF]
Physica A326 (2003) 256-264, 2003 In this paper we present an analysis of power law statistics on land markets. There have been no other studies that have analyzed power law statistics on land markets up to now. We analyzed a database of the assessed value of land, which is officially monitored and made available to the public by the Ministry of Land, Infrastructure, and Transport ...

Pollen limitation of native plant reproduction in an urban landscape
American Journal of Botany, Volume 109, Issue 12, Page 1969-1980, December 2022., 2022 Abstract Premise Evidence suggests that bees may benefit from moderate levels of human development. However, the effects of human development on pollination and reproduction of bee‐pollinated plants are less‐well understood. Studies have measured natural variation in pollination and plant reproduction as a function of urbanization, but few have ...

Autonomous Multirotor Landing on Landing Pads and Lava Flows [PDF]
arXiv, 2022 Landing is a challenging part of autonomous drone flight and a great research opportunity. This PhD proposes to improve on fiducial autonomous landing algorithms by making them more flexible. Further, it leverages its location, Iceland, to develop a method for landing on lava flows in cooperation with analog Mars exploration missions taking place in ...
