In this paper, we propose a method for global localization using an omni-directional camera. A robot position and angle are estimated by correlation coefficient between topological node-map images and input images. Near-node has the largest correlation coefficient in topological map images. The calculated correlation coefficient makes the mixtures of Gaussians density map. The highest value of ...

The angular turning probability density distribution for motile bacteria is usually measured in local coordinates and is therefore inconvenient for global analyses of the chemotactic bacterial migration. In this paper we present analytical derivations that convert the local angular turning probability density distribution into a global one. The explicit expression of a reduced global turning pr...

Traditional methods of chromite exploration are mostly based on geophysical techniques and drilling operations. They are expensive and time-consuming. Furthermore, they suffer from several shortcomings such as lack of sufficient geophysical density contrast. In order to overcome these drawbacks, the current research work is carried out to introduce a novel, automatic and opto-geometric image an...

We investigate the relation between thermodynamic and dynamic properties of an associating lattice gas (ALG) model. The ALG combines a three dimensional lattice gas with particles interacting through a soft core potential and orientational degrees of freedom. From the competition between the directional attractive forces and the soft core potential results two liquid phases, double criticality ...

1. introduction nowadays, remote sensing is considered as an important subject in many field studies, like agronomy, hydrogeology, mineral exploration, geography and geology. this knowledge has been applied in most of the geological fields. the significant application of remote sensing is preparation of lineament maps that is an important issue in the geological studies. in the remote sensing s...

Rough textures describe a general visual appearance of realworld materials with regard to view and illumination directions. As the massive size and dimensionality of such representations is a main limitation of their broader use, efficient parameterization and compression methods are needed. Our method is based on estimating the joint probability density of the included nine spatial, directiona...

It was noticed that in highway scenarios co-directional traffic consists of a collection of disconnected clusters. Since end-to-end connectivity between the sender and receiver is not guaranteed to exist, a car that stores a packet may have to carry it for a while, acting as a “data mule”, before a suitable next hop can be identified. We begin by offering a very simple analytical expression for...
