During the last few years several measurements of both the frequencies and wavelengths of laser radiations have been completed, from which values of the speed of light in vacuum, c, have been deduced. A detailed review of these measurements has been given by Rowley et al.. One of the ...
Speed of Light from Direct Laser Frequency and Wavelength Measurements: Emergence of a Laser Standard of Length Recent frequency and wavelength measurements of a methane stabilized laser yield a value of the speed of light 100 times less uncertain than the previously accepted value. Various possibiliti...
the light is emitted. The magnitude of light speedcin vacuum has been determined fromc = fλfor EM radiation of known frequencyfand wavelengthλ,and also separately by substituting measured values of permittivityeand permeabilityuinto the Maxwell formula. These methods produce the speed of light ...
Temperature is one of the most fundamental physical properties to characterize various physical, chemical, and biological processes. Even a slight change in temperature could have an impact on the status or dynamics of a system. Thus, there is a great ne
Phase transitions between different states of matter can profoundly modify the order in physical systems, with the emergence of ferromagnetic or topological order constituting important examples. Correlations allow the quantification of the degree of ord
The intra-individual variability of RT had a moderate power to differentiate NCD subgroups. The mean RT was able to discriminate the NCD-AD from NCD-vascular patients. Our findings highlight the clinical utility of the combined 'two-level' measurements of processing speed to distinguish between ...
The correction of the error of the measured wind speed induced by the motion of the floating LIDAR is needed. Although several studies have been carried ou... R Wakabayashi,T. Kawahigashi,A. Yamaguchi,... 被引量: 0发表: 2012年 ON ERRORS OF REFLECTIVITY MEASUREMENTS AND OF CALCULATIONS OF...
We propose an error correction procedure based on a cellular automaton, the sweep rule, which is applicable to a broad range of codes beyond topological quantum codes. For simplicity, however, we focus on the three-dimensional toric code on the rhombic d
Roughness measurements of engineering surfaces are an important and interesting application for optical sensors. The increased speed, the ability to measure 3D profiles, and the noncontact mode of optical sensors are of great interest for practical uses. A most challenging task is achieving comparability...
Another straightforward method is the usage of additional hardware sensors, e.g., dual-polarization antenna [12], array antenna [13], panoramic sky-pointing camera [14,15], 3D light detection and ranging (LiDAR) [16], inertial navigation system (INS) [17], etc. The effectiveness of these...
