ENO and WENO schemes
 

I need to understand ENO and WENO schemes.
Can any body tell me any website or paper from which i can understand the basics of the schemes... ( in easy and simple words)

Thanks

Paper: "Weighted Essentially Non-oscillatory Schemes on Triangular Meshes"

Paper: "Essentially Non-Oscillatory and Weighted Essentially Non-Oscillatory Schemes for Hyperbolic Conservation Laws"

Paper: "Efficient Implementation of Weighted ENO Schemes"

Also GoogleScholar search WENO and look into the Journal of Physics, Journal of Fluid Mechanics, and AIAA websites.
