Bilingually-Constrained (Monolingual) Shift-Reduce Parsing
Bilingually-Constrained (Monolingual) Shift-Reduce Parsing
2013/4/22
Jointly parsing two languages has been shown to improve accuracies on either or both sides. However, its search space is much bigger than the monolingual case,forcing existing approaches to employ com...

EXPERIMENTAL STARK SHIFT OF SEVERAL N II AND O II SPECTRAL LINES。
Mathematical model analysis was used to explain a regime shift of Takkobu Lake in Hokkaido Japan. In this lake, a catastrophic change occurred several years ago from a clear to a turbid water state. O...
Coherent Transport of Atomic Quantum States in a Scalable Shift Register
Coherent Transport Atomic Quantum Scalable Shift Register
2010/4/8
The coherent storage and transport of atomic quantum systems in versatile potential geometries are key elements for the investigation of quantum information processing and quantum degenerate gases. In...
Far-off resonance conditional phase-shifter using the ac-Stark shift
Far-off phase-shifter ac-Stark shift
2010/4/7
We propose a simple technique that achieves a conditional phase shift of pi radians between two weak lasers with energies at the 1000-photon level. The key idea is to set up a V-system with two far-of...
Influence of an Offshore Shift in the Gulf Stream on Waters of the South Carolina Continental Shelf
bottom pressure Gulf Stream midrecord shifts South Carolina Continental Shelf
2008/12/23
A 4.3-month-long dataset from moorings on the continental shelf off South Carolina during 1986 showed unusual midrecord shifts in bottom pressure, temperature, stratification, and alongshelf currents....
Directional Response of Wind Waves to a Large Wind Shift
Directional Response Wind Waves Large Wind Shift
2008/7/23
The directional response of a fully arisen sea to a 90° wind shift is studied using a combination of airborne radar and in situ directional wave observations. The observations were made in February 19...
Tropical Pacific 1976–77 Climate Shift in a Linear, Wind-Driven Model
Tropical Pacific Climate Shift Linear Wind-Driven Model
2008/6/13
A number of studies have attempted to explain the cause of decadal variability in the tropical Pacific and explore its possible link to decadal variability in the midlatitude Pacific. To investigate s...
Physiological steady state of phytoplankton in the field? An example based on pigment profile of Emiliania huxleyi (Haptophyta) during a light shift
Physiological steady state phytoplankton pigment profile Emiliania huxleyi a light shift
2014/4/21
A calcifying strain of Emiliania huxleyi was used to study the photoacclimation process during a shift from low (LL) to high (HL) photon flux density (PFD) under nutrient-replete and pH- and [CO2]-con...

基于Mean．shift的灰度目标跟踪新算法
目标跟踪 Mean—shift 方向编码 方向直方图 Bhattacharyya系数
2011/12/6
Mean—shift算法是一种非参数密度估计算法，可以实现快速的最优匹配，在目标的实时跟踪领域起着非常重要的作用。为了有效的将Mean—shift算法应用到灰度图像中，采用了以方向直方图建立目标模型的策略，提出了在灰度图像中以Mean—shift为核心的目标跟踪算法。实验结果表明，该算法具有不受光照条件影响的优点，在低对比度的情况下仍能实现稳定、实时的跟踪目标。
