Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Long-time behavior of Alfven waves in a flowing plasma
阿尔文波 流动 等离子体 长期行为
2023/4/28
In this talk, we consider the long-time behavior of the linearized MHD equations around a steady flowing plasma. We confirm the following physical phenomenon: there will be a generation of a magnetic ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Energy estimates for the two-dimensional acoustical rarefaction waves
二维声稀波 能量估计 无旋
2023/4/18
We study the two-dimensional acoustical rarefaction waves under the irrotational assumptions. We provide a new energy estimates without loss of derivatives. We also give a detailed geometric descripti...
Engineers use artificial intelligence to capture the complexity of breaking waves（图）
人工智能 破浪 复杂性 模型预测 海洋气候模拟
2023/6/19
Waves break once they swell to a critical height, before cresting and crashing into a spray of droplets and bubbles. These waves can be as large as a surfer’s point break and as small as a gentle ripp...
HIMAWARI-8 GEOSTATIONARY SATELLITE OBSERVATION OF THE INTERNAL SOLITARY WAVES IN THE SOUTH CHINA SEA
Himawari-8 Advanced Himawari Imager Internal Solitary Waves South China Sea
2018/5/14
The new generation geostationary meteorological satellite, Himawari-8 (H-8), was launched in 2015. Its main payload, the Advanced Himawari Imager (AHI), can observe the earth with 10-minute interval a...
Evaluation of numerical schemes for capturing shock waves in modeling proppant transport in fractures
Proppant transport Hyperbolic partial differential equations Frac pack Hydraulic fracturing
2018/4/2
In petroleum engineering, the transport phenomenon of proppants in a fracture caused by hydraulic fracturing is captured by hyperbolic partial differential equations (PDEs). The solution of this kind ...

Concurrent heat waves air pollution exacerbate negative health
2017/3/14
The combination of prolonged hot spells with poor air quality greatly compounds the negative effects of each and can pose a major risk to human health, according to new research from the University of...
The 31st International Symposium on Shock Waves (ISSW31) will be held July 9-14, 2017, at Toyoda Auditorium, Nagoya University, Nagoya, Japan. This will be the third ISSW held in Japan, after 26 years...
After a series of upgrades, the twin detectors of LIGO, the Laser Interferometer Gravitational-wave Observatory, have turned back on and resumed their search for ripples in the fabric of space and tim...

Liquefaction potential of coastal slopes induced by solitary waves
Coastal slopes Liquefaction Tsunami Wave–seabed interaction
2015/7/1
Tsunami runup and drawdown can cause liquefaction failure of coastal fine sand slopes due to the generation of high excess pore pressure and the reduction of the effective over burden pressure during ...
A demonstration of Alfvbn waves Part 1. Generation of standing waves By ANTONY JAMESON
Alfvbn waves Generation standing waves ANTONY JAMESON
2015/7/1
In this paper the equations for Alfvh waves are examined and conditions necessary for the occurrence of resonance are determined. An experiment using liquid sodium inside a torus is described. Waves w...
The dynamics of breaking internal solitary waves on slopes
internal waves stratified flows turbulent mixing
2015/6/30
Using direct numerical simulations (DNS), we investigate the structure and energetics of breaking internal waves on slopes. We employ a Navier–Stokes code in an idealized three-dimensional domain wher...
