We analyse the kinematics of ∼ 400 000 stars for which the RAdial Velocity Experiment (RAVE) has obtained spectra. These stars, half giants and half dwarfs, mostly lie within 2.5 kpc of the Sun. We decompose the sample into hot and cold dwarfs, red-clump and non-clump giants. The kinematics of the clump giants are consistent with being identical with those of the giants as a whole. Without binn...

Velocity models used for wavefield-based seismic imaging represent approximations of the velocity characterizing the area under investigation. The real subsurface velocity can at best be approximated by the combination of a known background velocity and unknown multi-scale heterogeneities. Here, we model the multi-scale heterogeneity assuming a fractal behavior and compare this type of heteroge...

A simultaneous measurement technique for the velocity distributions and scholar distributions, e.g., pressure, temperature, and so on, has been proposed. It visualized the spatial distribution using the multi-purpose particles, which has been coated with pressure-sensitive dye. The proposed particle technique, called the PSParticle method, is a hybrid system combining the technologies of pressu...

Two experiments examining the ability of human observers to detect differences in the statistical properties underlying velocity distributions were conducted. A four-alternative forced-choice methodology, using four simultaneous velocity distributions, was used in both experiments. In the first experiment the value of one statistical moment (mean, variance, skewness, or kurtosis) was manipulate...

This work introduces and studies a new family of velocity jump Markov processes directly amenable to exact simulation with the following two properties: (i) trajectories converge in law, when time-step parameter vanishes, towards given Langevin or Hamiltonian dynamics; (ii) stationary distribution process is always exactly by product Gaussian (for velocities) any target log-density. The itself,...
