Which coordinate system for modelling path integration?

Path integration is a navigation strategy widely observed in nature where an animal maintains a running estimate, called the home vector, of its location during an excursion. Evidence suggests it is both ancient and ubiquitous in nature, and has been studied for over a century. In that time, canonical and neural network models have flourished, based on a wide range of assumptions, justification...

Time: A Coordinate for Web Site Modelling

The adoption of high level models has been advocated by many authors as instrumental in Web site development as a strong support to both design and maintenance. We will discuss how the specification of Web sites at the logical level can greatly benefit from the introduction of specific features for the representation of time, which could also support the notions of versions and editions of obje...

Which way and how far? Tracking of translation and rotation information for human path integration.

Path integration, the constant updating of the navigator's knowledge of position and orientation during movement, requires both visuospatial knowledge and memory. This study aimed to develop a systems-level understanding of human path integration by examining the basic building blocks of path integration in humans. To achieve this goal, we used functional imaging to examine the neural mechanism...

Multiple-Goals Path Planning for Coordinate Measuring Machines

Path planning is a crucial step in automatic programming of coordinate measuring machines (CMMs). The goal is to generate an efficient and collision-free path for the CMM to inspect a collection of points. Previous research concentrates on path planning between two points, or sequencing the points without regard to obstacles and collisions. In this paper we propose a practical path planner that...
