Here we investigate the potential use of ALOS PALSAR L-band dual and quad polarization SAR data for improved forest structure mapping and parameter estimation. Several scenes of level 1.1 SLC data have been acquired under the DRAGON project in 2007 for the Tai-An test site of Shandong Province, P.R. China. The preliminary results for the first phase of this project are reported here. Firstly, t...

Modern mobile devices have become real personal computers, that increase the ability of building/extending existing applications by combining several technologies such as camera, GPS, 3D graphics and the Internet connection. Due to the permanent Internet accessing through mobile devices, advertising is a rapidly growing sector providing brands, agencies and marketers with the opportunity to con...

In this paper we propose a solution of a multiprocessor task scheduling problem with use of a new meta-heuristic inspired by a model of natural evolution called Generalized Extremal Optimization (GEO). It is inspired by a simple coevolutionary model based on a Bak-Sneppen model. One of advantages of the model is a simple implementation of potential optimization problems and only one free parame...

The official launch of the Chinese BeiDou Navigation Satellite System with global coverage (BDS-3) presents significant opportunities for various applications, including precision agriculture and autonomous driving, among others. With its spatial hybrid space constellation comprising geosynchronous Earth orbit (GEO), inclined (IGSO), medium (MEO) satellites, BDS can significantly contribute to ...

The mass spectromctnc study of the vaporization of the compounds GeO (hex) and GeO(am) and of the mixture GeO (hex) + Ge(c) made it *Z possible to establish their mode of vaporization: Ge02(hex) GeO(g) + 1/20 (I) n GeO(am) (GeO) (g) (n 1. 2. 3) (II) n n/2 GeOJhex) + n/2 Ge(c) (GeO) (g) (n = 1,2,3) (III) c. n The enthalpies of vaporization are AH° (I) 121. 2± 1.6 kcal/mole AH» (II, n=l) = 53.4 ±...

Investigations on the radiometric and geometric characteristics of IKONOS Geo satellite imagery and its use for orthoimage generation and 3D building reconstruction are reported. The paper first starts with an analysis of the radiometric quality of IKONOS Geo images of varying preprocessing and type, focussing on noise, edge quality and definition, and various artefacts. A noise estimation meth...

Based on the monitoring of five heavy metal elements in the surface sediments of the Pearl River in South China, potential toxicity of the heavy metals was assessed using consensus-based sediment quality guidelines (SQGs) method and geo-accumulation (I(geo)) index method. The monitoring results showed the heavy metal concentrations were significantly and positively correlated with each other, d...

The “GEO (Global Earth Observation) Grid” is aiming at providing an E-Infrastructure to understand our Earth more insightful and more precisely, but faster and easier to worldwide Earth Sciences community. On the E-Infrastructure we are able to share data, application programs, and scientific workflows without knowing deep knowledge in IT where the grid technology is provisioned. GEO Grid provi...
