Using 172 plates taken with the 40-cm astrograph of the Sternberg Astronomical Institute(Lomonosov Moscow University) in 1976–1994 and digitized with a resolution of 2400 dpi, we discovered and studied 275 new variable stars. We present the list of our new variables with all necessary information concerning their brightness variations. As in our earlier studies, the new discoveries show a rather large number of high-amplitude Delta Scuti variables, predicting that many stars of this type remain not detected in the whole sky. We also performed automated classification of the newly discovered variable stars based on the Random Forest algorithm. The results of the automated classification were compared to traditional classification and showed that automated classification was possible even with noisy photographic data. However, further improvement of automated techniques is needed, which is especially important when considering the very large numbers of new discoveries expected from all-sky surveys. 相似文献

The paper considers possibilities of applying laser strainmeters for the study of earthquake physics. One of laser strainmeters
is described. A high efficiency of using the laser strainmeters for the study of earthquakes and their precursors is shown.
In records of the spaced laser strainmeters, anomalous deformations propagating from the east to the west with the speed comparable
with that of migration of earthquakes were found. 相似文献

We present a new experimental platform for studies of turbulence and turbulent mixing in accelerating and rotating fluids.
The technology is based on the ultra-high performance optical holographic digital data storage. The state-of-the-art electro-mechanical,
electronic, and laser components allow for realization of turbulent flows with high Reynolds number (>107) in a relatively small form-factor, and quantification of their properties with extremely high spatio-temporal resolutions
and high data acquisition rates. The technology can be applied for investigation of a large variety of hydrodynamic problems
including the fundamental properties of non-Kolmogorov turbulence and turbulent mixing in accelerating, rotating and multiphase
flows, magneto-hydrodynamics, and laboratory astrophysics. Unique experimental and metrological capabilities enable the studies
of spatial and temporal properties of the transports of momentum, angular momentum, and energy and the identification of scalings,
invariants, and statistical properties of these complex turbulent flows. 相似文献

Pre-main sequence stars are bright UV (UV) sources compared with their main sequence analogues. The source of this excess
is the high energy processes associated with the physics of accretion/outflow during early stellar evolution. In this review,
the main sources of UV excess are described as well as the most significant “unknowns” in the field. Special emphasis is made
on the results from the last observations carried out with the Hubble Space Telescope and on the relevance of future dedicated
monitoring programs with the World Space Observatory-UV. 相似文献
