Extreme ultraviolet (EUV) solar flare emissions evolve in time as the emitting plasma heats and then cools.Although accurately modeling this evolution has been historically difficult, especially for empirical relationships, it is important for understanding processes at the Sun, alphaville clothing as well as for their influence on planetary atmosp
MAV systems have found increased attention in the photogrammetric community as an (autonomous) image acquisition platform for accurate 3D reconstruction.For an accurate reconstruction in feasible natio celebrate eyeshadow palette time, the acquired imagery requires specialized SfM software.Current systems typically use high-resolution sensors in pr
Wind speed and direction are important parameters in meteorological observation.A solid wind sensor is needed with a small quadcopter for boundary layer meteorological observation.In this paper, the principle of a cylindrical two-dimensional wind sensor is reported and click here the data from wind tunnel experiments are analyzed.A model is propose
Some aspects of one-mineral geological environment indicators are discussed.Factors controlling the composition of biotite in different click here P, T, and chemical environments are reviewed.On the basis of theoretical considerations and empirical observation it is concluded that biotites in igneous granites may tend to be somewhat richer in iron
