In this paper conservative nite diierence schemes for scalar conservation laws are studied. Lax-Wendroo (L-W) schemes, Engquist-Osher (E-O) schemes and monotone schemes are models for this study. A weighted L 2 (R)-norm space is constructed to show linear and nonlinear stability of a discrete shock proole connecting two ends (u l ; u r). Existence of discrete shock prooles with small perturbati...
While holding great development opportunities to be seized, Africa has been identified as particularly vulnerable to climate changes, and the ZRB is no exception to that. With increasing demands to the Zambezi system in terms or water and energy, and rising challenges in the form of less runoff due to climate change, it is paramount to plan ahead. In particular, it must be understood how major ...
The Agricultural Policy Environmental eXtender (APEX) model is capable of estimating edge-of-field water, nutrient, and sediment transport and is used to assess the environmental impacts of management practices. The current practice is to fully calibrate the model for each site simulation, a task that requires resources and data not always available. The objective of this study was to compare m...
Using the most recent atmospheric neutrino data, as well as short-baseline, longbaseline and tritium β-decay data we show that the joint interpretation of the LSND, solar and atmospheric neutrino anomalies in (3+1) sterile neutrino schemes is severely disfavored, in contrast to the theoretically favored (2+2) schemes.
There are methods of supplying the required energy to load while reducing cost relatively, but do not take into account amount reserved energy; this is preferred if batteries used store excess produced. The proposed method a mathematical model calculate system size for in an area far from electrical grid where there huge sources biomass and high rates solar radiation. includes three generate en...
