High-precision measurement of the thermal exponent for the three-dimensional XY universality class
Accuracy of measurement measurement superfluids lipase
2014/12/20
Simulation results are reported for the critical point of the two-component ϕ4 field theory. The correlation-length exponent is measured to high precision with the result ν=0.6717(3). This value ...
Precision Measurement of CP Violation in D0->pi+pi- at CDF
Precision Measurement CP Violation D0->pi+pi- at CDF
2011/1/4
We report a preliminary measurement of the CP violating asymmetry in D0 →p+p− using approximately 215·000 decays reconstructed in about 5.94 fb−1 of CDF data.
Precision Measurement of KS Meson Lifetime with the KLOE detector
Precision Measurement KS Meson Lifetime KLOE detector
2011/1/4
Using a large sample of pure, slow, short lived K0 mesons collected with KLOE detector at
DANE, we have measured the KS lifetime. From a fit to the proper time distribution we find τ (KS) = (89.562 ...
Precision measurement of the 5 2S1/2 - 4 2D5/2 quadrupole transition isotope shift between 88Sr+ and 86Sr+
Precision measurement 88Sr+ 86Sr+
2010/10/21
We have measured the isotope shift of the narrow quadrupole-allowed 52S1=2 - 42D5=2 transition
in 86Sr+ relative to the most abundant isotope 88Sr+. This was accomplished using high-resolution laser ...
Environment Assisted Precision Measurement
Precision Measurement trapped ions clock sensitivity
2010/3/10
We describe a method to enhance the sensitivity of precision measurements that takes advantage of a quantum sensor's environment to amplify its response to weak external perturbations. An individual q...
基于最小二乘支持向量回归的小零件精密测量技术（Precision Measurement Technology for Small Parts Using LSSVR）
齿形链板 精密测量 图像处理
2009/9/11
以圆销式齿形链板为研究对象，提出了结合图像处理技术和最小二乘支持向量回归的小零件精密测量方法。以CCD作为传感器采集图像，通过去噪和二值化等图像预处理技术获得待测零件单像素边缘轮廓信息。根据零件特点确定待测区域，并取出该区域中图像点的坐标作为最小二乘支持向量回归的训练点集，进行直线和圆的亚像素回归。对回归结果进行处理得到待测直线间夹角、圆孔直径、圆度误差和圆心距等几何参数。实验结果表明提出的方法不...
