The numerical study on active control strategies of T-foil

Zhongguo Jianchuan Yanjiu, 2021
ObjectivesAn active control T-foil can effectively improve the longitudinal anti-rolling motion of the ship, but there is still no conclusion on what control strategy has the best anti-rolling effect.

The ULF wave foreshock boundary: Cluster observations [PDF]

, 2015
The interaction of backstreaming ions with the incoming solar wind in the upstream region of the bow shock gives rise to a number of plasma instabilities from which ultra-low frequency (ULF) waves can grow.

The Martian bow wave—Theory and observation [PDF]

Planetary and Space Science, 1972
Refinement of the relationship between the trajectory of Mariner 4 in its fly-by of Mars and the calculated location of a proposed Martian bow arising from interaction of the solar wind and the ionosphere by inclusion of aberration effects of the planet's motion about the sun.

The performance of bow foils in irregular and oblique waves

Applied Ocean Research
Bow foils are an emerging energy saving device that utilise wave energy to improve the efficiency of ships operating in waves, through both a reduction in ship motions and the generation of additional thrust.

Study of fluctuations in the Martian magnetosheath using a kurtosis technique: Mars Express observations

Earth and Planetary Physics, 2022
Planetary magnetosheaths are characterized by high plasma wave and turbulence activity. The Martian magnetosheath is no exception; both upstream and locally generated plasma waves have been observed in the region between its bow shock and magnetic ...

Structural and Electronic Instabilities in Polyacenes: Density Matrix Renormalization Group Study of a Long--Range Interacting Model [PDF]

, 2001
We have carried out Density Matrix Renormalization Group (DMRG) calculations on the ground state of long polyacene oligomers within a Pariser-Parr-Pople (PPP) Hamiltonian.

Mesoscale modeling of Venus' bow-shape waves [PDF]

Icarus, 2020
The Akatsuki instrument LIR measured an unprecedented wave feature at the top of Venusian cloud layer. Stationary bow-shape waves of thousands of kilometers large lasting several Earth days have been observed over the main equatorial mountains. Here we use for the first time a mesoscale model of the Venus's atmosphere with high-resolution topography ...

Phase diagram of the one-dimensional half-filled extended Hubbard model

, 2007
We study the ground state of the one-dimensional half-filled Hubbard model with on-site (nearest-neighbor) repulsive interaction $U$ ($V$) and nearest-neighbor hopping $t$.

The return of the bow shock

, 2013
Recently it has been discussed whether a bow shock ahead of the heliospheric stagnation region does exist or not. This discussion was triggered by measurements indicating that the Alfv\'en speed and that of fast magnetosonic waves are higher than the ...
