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 Frequency and Wavelength Measurements of the Methane-Stabilized Laser 来自 ResearchGate 喜欢 0 阅读量: 51 作者:KM Evenson,JS Wells,FR Petersen,BL Danielson,JL Hall 摘要: The frequency and wavelength of the methane-stabilized laser at 3.39 μm were directly measured ...
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
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
Vane anemometer – measurements of wind speed Thevane anemometeris a classic wind speed meter which is now very commonly used, not only outdoors, but also indoors. Easy handling makes it possible to measure airspeed quickly using the impeller anemometer. ...
Strain analysis from high-resolution transmission electron microscopy (HRTEM) images offers a convenient tool for measuring strain in materials at the atomic scale. In this paper we present a theoretical study of the precision and accuracy of surface str
Imaging in scattering media using the phase of modulated light sources Intensity transmission measurements of biological tissue with light in the wavelength range from 600 nm to 1000 nm yields limited resolution due to strong ... P Kraemmer,H Bartelt,H Fischer,... - International Society for Opt...
Foremost is how auroral electrons are accelerated before colliding with the ionosphere and producing auroral light. Powerful Alfvén waves are often found traveling Earthward above auroras with sufficient energy to generate auroras, but there has been no direct measurement of the processes by which ...
Measuring neuronal tuning curves has been instrumental for many discoveries in neuroscience but requires a priori assumptions regarding the identity of the encoded variables. We applied unsupervised learning to large-scale neuronal recordings in behaving
is possible to exploit the quantumness of the reservoir and to obtain ideal performance both for memory and forecasting tasks with two successful measurement protocols. One repeats part of the experiment after each projective measurement while the other employs weak measurements operating online at the...
