How can you have a proof without proving anything? Mathematicians found a way and, in the process, came to blows over it – ...

You can use the Phase Plane and Slope Field apps to qualitatively analyze ordinary differential equations (ODEs). Phase Plane app: Analyze two-dimensional autonomous ODE systems. Slope Field app: ...

Tensegrity structures are geometric nonlinear systems and statically and kinematically indeterminate structures that require an initial shape-finding procedure to establish a self-equilibrium state.

Concrete is used in the construction of high-rise buildings, large bridges, viaducts and other structures for a wide range of applications, and damage to the internal structure of concrete may to lead ...

In this work, a CMFS method based on the analogy equation method, the radial basis function and the method of fundamental solutions for linear and nonlinear convection-diffusion equations in ...

The dynamics of flash drums is simulated using a formulation adequate for phase modeling with equations of state (EOS). The energy and mass balances are written as differential equations for the ...

Latent variable models (LVMs) are powerful tools for discovering hidden structure in data. Canonical LVMs include factor analysis, which explains the correlation of a large number of observed ...
