人工智能 聚变实验 等离子体边缘
2023/6/21
To make fusion energy a viable resource for the world’s energy grid, researchers need to understand the turbulent motion of plasmas: a mix of ions and electrons swirling around in reactor vessels. The...

Local Convertibility Edge States Quantum Many Body Systems
2016/1/22
In some many-body systems, certain ground-state entanglement (Rényi) entropies increase even as the correlation length decreases. This entanglement nonmonotonicity is a potential indicator of nonclass...
SUB-PIXEL EDGE LOCALIZATION BASED ON LASER WAVEFORM ANALYSIS
Urban Analysis Laser scanning LIDAR Edge Sub-pixel precision
2015/8/13
Laser range data is of high interest in photogrammetry. However, compared to passive imagery, it usually has a lower image
resolution, making geometry extraction and modeling challenging. A method t...

2015/5/12
The primary mirror segments are passively constrained in the three lateral degrees of freedom. We evaluate the segment
lateral motions due to the changing gravity vector and temperature, using site ...
The Thirty Meter Telescope project will design and build a thirty-meter diameter telescope for research in astronomy at
optical and infrared wavelengths. The highly segmented primary mirror will use...

2014/12/18
An ultrathin polymer sheet floating on a fluid forms a periodic pattern of parallel wrinkles when subjected to uniaxial compression. The wave number of the wrinkle pattern increases sharply near the f...
