Detailed person-specific data, present in the centralized server or in the distributed environment, in its … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 6,841 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantitative Performance of Spectral Indices in Large Scale Plant Health AnalysisHelmi Zulhaidi Mohd Shafri, Mohanad Saad EzzatProblem statement: Oil palm trees are planted in large scale areas. The detection and mapping of diseases are considered as important for oil palm industry and need a timely detection to control the disease spread. Approach: Vegetation analysis of airborne hyperspectral imagery could be an ideal method to deal with this problem since this data could be acquired on user … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 8,226 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Vegetation Dynamics using Long-Term Normalized Difference Vegetation Index Time-SeriesTamara Bellone, Piero Boccardo, Francesca PerezProblem statement: The Normalized Difference Vegetation Index (NDVI) is the most extensively used satellite-derived index of vegetation health and density. Since climate is one of the most important factors affecting vegetation condition, satellite-derived vegetation indexes have been often used to evaluate climatic and environmental changes at regional and global scale. The proposed study attempted to investigate the temporal vegetation dynamics … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study on Potentiality of Carbon Storage and CO2 Uptake in the Biomass and Soil of Coppice StandA. Khademi, S. Babaei, A. MatajiProblem statement: Enhancing carbon storage in terrestrial ecosystems, especially in the forests, is a key factor in maintaining the atmosphere's carbon balance. With regard to the importance of forest in carbon sequestration, this study attempted to investigate the carbon storage potential and CO2 uptake in oak coppice stand. Approach: After combining slope, aspect and hypsometric maps, the number of land … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,925 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study of Changing Drainage Basin System with Tectonic Forms, Case Study: Lut Block, IranEbrahim MoghimiThe study area locates in the east of Iran and it is morphologic block (unit). Problem statement: Sharp contrasts in the appearances of landscapes such as drainage basins with litology (kind of rock), tectonic regime, folding and climatic effect had been inspired geomorphologies in the past and now to devise schemes to explain those contrasts. These contrasts also remained and … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,274 accessesView PDFCite
Research ArticleOpen accessIn the abstractHow to Guide and Assess Risk Reduction using Risk Characterization IndicatorsPeter Borgen Sørensen, Rainer Brüggemann, Marianne Thomsen et al.Problem statement: The risk level predictions in risk assessment often suffer from uncertainties and may, thus, overlook some adverse effects. This problem can be reduced by using risk reduction strategies that continuously guide activities toward lowest possible risk. Approach: This study suggested a method to guide and assess such risk reduction strategies using multi-indicator risk characterization. It was a challenge … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,038 accessesView PDFCite
