Any straight line graph has a constant gradient, which is calculated by the change in 𝑦 divided by the change in 𝑥, along any section of the graph. The gradient is measuring the steepness of the ...

We show that Carathéodory's conjecture on umbilical points of closed convex surfaces may be reformulated in terms of the existence of at least one umbilical point in the graphs of functions f: R 2 → R ...

The dielectric constant for top soil at nearly static conditions has been found to vary from a relative value of 3 for dry soils to as high as 500 for saturated top soils. If an experiment is ...
