The purpose of this letter is to define a distance on the underlying phase space of a chaotic map, based on natural invariant density of the map. It is observed that for logistic map this distance is equivalent to Wootters’ statistical distance. This distance becomes the Euclidean distance for a map with constant invariant density. ∗Postal Address: 1110, 36-C, Chandigarh -160014, India

The larval community of coral reef fishes in the Red Sea was studied in coastal and offshore sites to determine the effects of the exposure to waves and currents and the distance from the shore in structuring the larval fish community. Plankton sampling from inshore and offshore sites and the exposed and sheltered sides of the reefs resulted in the collection of 2048 larvae representing 49 diff...

Background and Objective: This study aims at investigating the vulnerability of areas in the eighth municipal district of Tehran. In this research, the indices of distance from fault, maximum earth acceleration, soil permeability, landslide, liquefaction, population density, land use, ground floor area, type of building materials, and age of buildings were identified, examined, and analyzed sta...

Centaurea glastifolia, a plant species from the Asteraceae family, is distributed in the Northwest of Iran. This study carried out to determine suitable habitats and habitat connectivity of Centaurea glastifolia in three Provinces of West Azarbayejan, East Azarbayejan and Ardabil. Seven habitat variables and 36 presence points were selected for habitat modelling using six habitat distribution m...

Vegetation in any landscape reflects its health condition. Monitoring land use change and land cover plays a key role in environmental planning and management. Mazandaran province has always been considered by tourists due to its high tourism potential and consequently the vegetation, especially the forest, has been damaged. In this study, vegetation Contiguity and integrity in Mazandaran using...

primary information about different methods of vegetation sampling is important to researchers to decide about their sampling. in this study we applied five distance methods (closest individual, nearest neighbor, random pairs, point-centered quarter and angle orderd) to estimate plant density in three vegetation types including artemisia sieberi, juncus littoralis and punica granatum in mazanda...

A new, efficient method of deriving stellar number density distribution along a line of sight from star count data by using a Linear Programming technique is presented. The derived stellar number density distribution is further used to find a distance to a dark globule. In order to validate the algorithm, we select a dark globule Barnard 361 with known stellar number density distribution and di...
