To compare and integrate brain data, data from multiple subjects are typically mapped into a canonical space. One method to do this is to conformally map cortical surfaces to the sphere. It is well known that any genus zero Riemann surface can be mapped conformally to a sphere. Since the cortical surface of the brain is a genus zero surface, conformal mapping offers a convenient method to param...

Historic contexts remind us of an era when cities were built based on the needs, goals, and preferences of their inhabitants. In other words, the mental world of both the builders and the inhabitants was closely interrelated. But by ignoring citizens' memories and interests and their mental needs, today's interventions with rapid developments within historic contexts have led to amnesia and the...

Selecting landmarks for use by a navigating mobile robot is important for map-building systems. However, it can also provide a way by which robots can communicate route information, so that one robot can tell another how to find a goal location. A route through an environment can be described by the landmarks encountered along the path, and a robot following the same path must identify the perc...
