If \(f^\prime\left(x\right) > 0\), the function \(f\left(x\right)\) is increasing (slopes are positive). The derivative graph lies above the \(x\)-axis If \(f^\prime ...

Some standard modules for making 3d shapes with attachment support, and function forms that produce a VNF. Also included are shortcuts cylinders in each orientation and extended versions of the ...

The Arctic is warming faster than anywhere else on the planet, and as a result, sea ice in the Arctic Ocean is decreasing. Sea ice loss has far-reaching effects on the planet because the ice helps ...

Shear wave velocity is an essential elastic rock parameter for reservoir characterization, fluid identification, and rock physics model building. However, S-wave velocity logging data are often ...

It remains to be determined how different inputs for memory-encoding, such as the use of paper notebooks or mobile devices, affect retrieval processes. We compared three groups of participants who ...

A major focus of social network analysis is attempting to find central “influencers” or “opinion leaders” who can hasten or slow the spread of a social contagion. Using a simulation, we demonstrate ...

We looked at Maxima in the February 2011 issue to do algebra and rearrange some equations. But those aren't the only tricks up Maxima's sleeve. This month, I describe how Maxima can help with ...

In this work we present a simple and fast computational method, the visibility algorithm, that converts a time series into a graph. The constructed graph inherits several properties of the series in ...
