On mapping complete binary trees into grids and extended grids
Proceedings Fourth International Symposium on Parallel Architectures, Algorithms, and Networks (I-SPAN'99), 2003We consider one-to-one, congestion one layouts of complete binary trees into 2-D grids and extended 2-D grids. For such a layout of the complete binary tree T/sub h/ of height h into the square n/spl times/n grid we consider the layout's expansion ratio r=n/sup 2//(2/sup h+1/-1). For r the least expansion among layouts of T/sub h/ into grids, we obtain

Semantical occupancy grid mapping framework
2017 European Conference on Mobile Robots (ECMR), 2017In recent decades, mapping has been increasingly investigated and applied in unmanned terrain, aerial, sea, and underwater vehicles. While exploiting various mapping techniques to build an inner representation of the environment, one of the most famous remaining is occupancy grid mapping.

Metro Maps on Flexible Base Grids
17th International Symposium on Spatial and Temporal Databases, 2021We present new generic methods to efficiently draw schematized metro maps for a wide variety of layouts, including octilinear, hexalinear, and orthoradial maps. The maps are drawn by mapping the input graph to a suitable grid graph. Previous work was restricted to regular octilinear grids.

GRID superscalar and job mapping on the reliable grid resources
2008The dynamic nature of grid computing environment requires some predictions regarding resource reliability and application performance. In such environments, avoiding resource failures is as important as the overall application performance. The aim of this work is to identify the most available, least-loaded and fastest resources for running an ...

Evaluation of grid-map sensor fusion mapping algorithms
2007 IEEE International Conference on Systems, Man and Cybernetics, 2007This paper presents a thorough evaluation of grid map based sensor fusion algorithms for mapping the environment of a mobile robot. Three physical sensors were used for creating the grid maps: a CCD camera, a set of ultrasonic sensors and a laser rangefinder.

A survey of task mapping on production grids
ACM Computing Surveys, 2013Grids designed for computationally demanding scientific applications started experimental phases ten years ago and have been continuously delivering computing power to a wide range of applications for more than half of this time. The observation of their emergence and evolution reveals actual constraints and successful approaches to task mapping across

FPGA-Accelerated Particle-Grid Mapping
2016 IEEE 24th Annual International Symposium on Field-Programmable Custom Computing Machines (FCCM), 2016Computing the forces derived from long-range electrostaticsis a critical application and also a central part of MolecularDynamics. Part of that computation, the transformation of a charge grid to a potential grid via a 3D FFT, has received some attentionrecently and has been found to work extremely well on FPGAs.

GRID IMAGING FOR A TWO-DIMENSIONAL MAP
International Journal of Bifurcation and Chaos, 1991By examining images of grids as they fold and stretch under the action of two-dimensional maps, we determine the geometry of the maps and use this to study their dynamics and bifurcations. In particular, we explain important features of the complicated dynamics and rich bifurcation structure of a map designed as a model of two coupled neurons.

Evidential Grid-Based Tracking and Mapping
IEEE Transactions on Intelligent Transportation Systems, 2016Tracking and mapping the local environment form the basis of an autonomous vehicle system. They are often realized separately using occupancy grids, which do not require object or shape assumptions, and model-based object tracking algorithms. Many approaches require a binary classification of the sensor measurements into coming from a static or from a ...

A grid portal to improve SST maps
2007 2nd International Workshop on Advances in Sensors and Interface, 2007New technologies, sensors and techniques increase every day the human capabilities to monitoring the ecosystem and understanding the anthropogenic influence in its evolution. Particularly remote sensing, offering the possibility of covering large spatial area with a high temporal frequency, represents the ideal solution to environmental monitoring, but
