Oztekin, Dennis Ekin, "The Lattice Boltzmann Methods and Their Applications to Fluid Flows" (2014). Theses and Dissertations. Paper 1581.
"The history of the Lattice Boltzmann Method and its application to fluid mechanics are
investigated here. Detailed formulations are provided to form a basis for the Lattice
Boltzmann Method and its many variations. These variations are designed to overcome
shortcomings in the standard single relaxation time Lattice Boltzmann model. Presented
here are: a model that utilizes the non-equilibrium parts of the stress tensor, the
Regularized Lattice Boltzmann model; a model that converts over to momentum space,
the Multi-Relaxation Time Lattice Boltzmann model; and a model that corrects itself
using the entropy equation, the entropic Lattice Boltzmann model. Extensions for the
Lattice Boltzmann method are derived that include: external forces, multiphase flows,
and thermal flows. Various types of boundary conditions are modeled using different
approaches. A detailed explanation on extracting common macroscopic flow properties in
physical units is provided. These extracted properties can be used to check temporal and
spatial convergence. A two dimensional, nine velocity model and a three dimensional,
fifteen velocity model are used to provide examples of a number of the approaches
mentioned. A two dimensional and three dimensional lid-driven cavity flow is used to
illustrate these methods. "

"The Page Visibility API lets you know when a webpage is visible or in focus. With tabbed browsing, there is a reasonable chance that any given webpage is in the background and thus not visible to the user. When the user minimizes the webpage or moves to another tab, the API sends a visibilitychange event regarding the visibility of the page. You can detect the event and perform some actions or behave differently." Occurs regularly on mobile browsers.

While it’s relatively easy to cache static resources, things like forms that require server interaction are harder to optimize. It is possible to provide a somewhat useful offline fallback though."

When a DNS lookup is performed on an endpoint of this type, it returns an “A” record with an IPv4 address and an “AAAA” record with an IPv6 address. In most cases the network stack in the client environment will automatically prefer the AAAA record and make a connection using the IPv6 address."
