Rotating Space Elevators: Classical And Statistical Mechanics, Steven Knudsen Jan 2015

Rotating Space Elevators: Classical And Statistical Mechanics, Steven Knudsen

Graduate Theses, Dissertations, and Problem Reports (ETD)

We investigate a novel and unique dynamical system, the Rotating Space Elevator (RSE). The RSE is a multiply rotating system of strings reaching beyond the Earth geo-synchronous satellite orbit. Objects sliding along the RSE string ("climbers") do not require internal engines or propulsion to be transported far away from the Earth's surface. The RSE thus solves a major problem in the space elevator technology which is how to supply the energy to the climbers moving along the string. The RSE is a double rotating floppy string. The RSE can be made in various shapes that are stabilized by an approximate …

Avoidance Of Token-Loss By Pigeons, James E. Cook

Graduate Theses, Dissertations, and Problem Reports (ETD)

The response-dependent delivery and removal of tokens can reinforce and punish the responding of humans and nonhuman animals. The responding of humans can be maintained by the avoidance of token-losses, but this has not been demonstrated with nonhuman animals. Across three experiments, it was demonstrated that the responding of pigeons could be maintained in a token-loss avoidance arrangement. Tokens were delivered response-independently at the beginning of a token-loss avoidance period. Tokens were scheduled to be removed on a variable-cycle schedule. Responding canceled scheduled token-losses. Those tokens that remained were exchangeable for food during programmed exchange periods. Several parameters of the …
