Visualization of Developmental Processes by Extrusion in Space-time
Developmental processes in nature may involve complex changes in the topology, shape, and patterns of growing structures. Processes taking place in one or two dimensions can be visualized as objects in three-dimensional space, obtained by extruding the growing structures along a line or curve representing the progress of time. In this paper, we extend the notion of L-systems with turtle interpr...
متن کاملSpace-Time Routing in Ad Hoc Networks
We introduce Space-Time Routing (STR), a new approach to routing in mobile ad hoc networks. In STR, the age of routing state is considered jointly with the distance to the destination. We give a general description of STR, which can accommodate various temporal (age) and spatial (distance) metrics. Our formulation of STR describes a family of routing algorithms, parameterized by a choice of nod...
متن کاملRouting in Space and Time in Networks with Predictable Mobility
We consider the problem of routing in emerging wireless networks where nodes move around explicitly carrying messages to facilitate communication in an otherwise partitioned network. The absence of a path at any instant of time between a source and destination makes the traditional mobile ad hoc routing protocols unsuitable for these networks. However, the explicit node movements create paths “...
متن کاملThe Role of Virtual Space and Social Networks in Health and Fitness Industry
Background & Aims: World population growth and increasing expectations for effective treatments and a generally better quality of life are putting increasing pressure on healthcare Therefore, health care is still one of the most important social and economic challenges worldwide and requires new and more advanced solutions from science and technology (1, 2). In response to such needs, since the...
متن کاملPrinciples and networks for self-organization in space-time
In this paper, we develop a spatio-temporal memory that blends properties from long and short-term memory and is motivated by reaction diffusion mechanisms. The winning processing element of a self-organizing network creates traveling waves on the output space that gradually attenuate over time and space to diffuse temporal information and create localized spatio-temporal neighborhoods for clus...
