Many of the ideas and controversies regarding the origin, evolution, and significance of avian migration derive from investigations of Old World migrants wintering in the European subtropics and central African Tropics. One of the critically important studies in the development of these ideas was the work by Morel & Bourlière (1962) on migratory bird ecology in Senegal, from which they conclude...

In this article, the possibility of using artificial neural networks for road detection from high resolution satellite images is tested on a part of RGB Ikonos and Quick-Bird images from Kish Island and Bushehr Harbour respectively. Then, the effects of different input parameters on network’s ability are verified to find out optimum input vector for this problem. A variety of network structures...

With the rapid development of RS and more mature and the precision of number of field surveys on the basis of Quick-Bird remote sensing data through visual interpretation of urban public green vegetation diversity survey the exits of mixed. Pixel mixed is one important factor of influence accuracy of Remote sensing image classification. In this article, combine genetic algorithm with BP propaga...

The paper explores and assesses the potential uses of high resolution satellite imagery and digital image processing algorithms for the auto detection and extraction of geospatial features, farmlands, for the purpose of statutory plane surveying tasks. The satellite imagery was georectified to provide the planar surface necessary for morphometric assessments followed by integrated image process...

In this paper, space image of the Quick Bird satellite a pixel size 0.6m*0.6m for year 2007 were merge layers through layer stack process from seven to three and combined in color composites using ERDAS Imagine Ver. 9.2. Also monitoring ground control points with coordinates E, N, monitored by Differential Ground Position System (DGPS) device these are processed OPUS site internet. The results ...

Against the Spectrum distortion problem of the IHS method which exists in the Quick-Bird data fusion, the paper proposes visualpan band method and Linear weighted matching two methods to improve it, provides the best value scope of the α in the VisualPan band method as well as the best weighted values of pan and I when the spatial characteristic and the spectrum characteristic of the linear wei...

This paper provides a game-theoretic model of probabilistic voting and then examines the incentives faced by candidates in a spatial model of elections. In our model, voters’ strategies form a Quantal Response Equilibrium (QRE), which merges strategic voting and probabilistic behavior. We first show that a QRE in the voting game exists for all elections with a finite number of candidates, and t...

Quantal response equilibrium (QRE) has become a popular alternative to the standard Nash equilibrium concept in game theoretic applications. It is well known that human subjects do not regularly choose Nash equilibrium strategies. It has been hypothesized that subjects are limited by strategic uncertainty or that subjects have broader social preferences over the outcome of games. These two fact...
