Introduction. Urban areas are central to sustainability. They generate more than 75% of global GDP, contribute to about 75% of carbon emissions from global final energy use, and produce approximately 2 billion tons of waste per year (Hoornweg and Bhada-Tata, ; Seto et al., ).Every week, the global urban population increases by about 1 by: This book presents bootstrap resampling as a computing-intensive method able to meet the challenge.
It shows the bootstrap to perform reliably in the most important statistical estimation techniques: regression, spectral analysis, extreme values and book is written for climatologists and applied statisticians. The survey was conducted within an area of approximately 11 km × 10 km around the village of Barkedji (° N; ° W) in the Ferlo pastoral area (Northern Senegal) (Figure 1).Characterized by a semi-arid climate, the study area is made of a complex and dense network of ponds located within the fossil Ferlo river bed that are filled during the rainy season (from Cited by: spectral thermal climate crop sensing of water sensors urban studies detection regions temporal doi biomass spatial resolution applications wetlands pixel wetland You can write a book review and share your experiences.
