Equations (2) differ from classical ID shallow water equations (Didenkulova, 2009) only by an additional coefficient 2/3 in the first equation, which is determined by the parabolic
shape of the channel cross-section.
It is well known that the lattice of standard parabolic
subgroups, ordered by inclusion, is isomorphic to the Boolean lattice.
The SkyTrough(tm) is a breakthrough design patterned after the best of the previous utility-scale parabolic
troughs with several critical innovations that improve performance and significantly reduce cost.
trough power plants consist of numerous trough-shaped parabolic
mirrors that concentrate sunlight onto receivers (absorber tubes) that are located along the focal line.
flight, a aeroplane goes temporarily into freefall providing the students with up to 22 seconds of zero-gravity.
In running, the model shows that the energy efficiency derives mostly from the fact that the runner spends considerable time flying through the air, at no energy cost, along parabolic
The triangular footprint is crowned by a dramatically undulating roof made up of five interlinked parabolic
arches, clad with large terracotta tiles to create a light, articulated structure.
The zero-gravity flights are given on airplanes that travel in a high-speed parabolic
pattern, which delivers several haft-minute episodes of weightlessness.
An immense scaffolding, looking something like a housing project bristling with ventilators, parabolic
antennae, and megaphones, covered the last wall of the mezzanine.
He illustrates the parabolic
reality as it takes form in a radical faith community called the Church of Hope in Tulsa, Oklahoma.
The geometries of paleosols in the massive parabolic
dunes indicate that this activity involved the inland migration of parabolic
dunes during a period of net beach recession.
The problem is to choose whether to fit a line (of the form y = a + bx) or a parabolic
function (of the form y = a + bx + [cx.
