In 2003, as part of a program of archaeological survey in the southern part of Kurnool District in Andhra Pradesh, south India, a series of previously unreported rock art sites were recorded. These primarily consist of pictographs, painted onto the walls of quartzite rock shelters and boulders. They appear to cover a range of time periods from the present day and potentially extending back into...

Across cultures and languages, people find similarities between the products of different senses in mysterious ways. By studying what is called cross-modal correspondences, cognitive psychologists discovered that lemons are fast rather than slow, boulders are sour, and red is heavier than yellow. Are these cross-modal correspondences established via sensory perception or can they be learned mer...

• Planning the coordinated motion of a group of agents who wish to move to a specified location amidst many obstacles • Planning the motion of an articulated skeletal model subject to constraints, such as maintaining hand contact with a door handle or avoiding collisions while passing through through a narrow passageway • Planning the motion of a character while navigating through a dense crowd...

The force required to pull 7t and 40t polyhedral boulders from the surface of an asteroid is simulated using the discrete element method considering the effects of microgravity, regolith cohesion and boulder acceleration. The connection between particle surface energy and regolith cohesion is estimated by simulating a cohesion sample tearing test. An optimal constant acceleration is found where...

In order to understand the geological evolution of asteroids Eros, Itokawa and Ryugu their collisional history, previous studies investigated boulder size distributions on surfaces. However, quantitative comparison these is hampered by numerous differences between regarding definition a boulder's size, measuring technique fitting method determine power-index distributions. We provide consistent...

Abstract Large granitic boulders resting on steep slopes represent considerable safety hazards that largely depend the location of contact surface characterized by impression d , denoting parallel distance between and original rock surface. On other hand, this reflecting often convex nature platforms, cannot be measured precisely, so Factors Safety (FoS) computed with input may have significant...

Abstract Among sites of geomorphological interest in the tableland Stołowe Mountains, consisting clastic sedimentary rocks Late Cretaceous age, are enigmatic occurrences and clusters sandstone boulders within plateau levels that underlain by mudstones marls. These allochthonous, having been derived from quartz beds support upper level stratigraphically excess 50 m above altitudinal position bou...
