The LAMOST spectral survey provides a rich databases for studying stellar spectroscopic properties and chromospheric activity. We cross-matched a total of 105,287 periodic variable stars from several photometric surveys and databases (CSS, LINEAR, Kepler, a recently updated eclipsing star catalogue, ASAS, NSVS, some part of SuperWASP survey, variable stars from the Tsinghua University-NAOC Transient...
In this paper, we develop a hybrid chemical reaction optimization algorithm (HCRO) to solve the onedimensional bin packing problem (1-D BPP). We apply our method to 1615 benchmark instances and compare the results to those found in the literature. We find that our procedure produces highquality solutions very quickly and the results show that HCRO can be considered as one of the best algorithms for...
Load balancing (LB) plays a key role in improving the performance of hybrid Geostationary Orbit (GEO)-Low Earth Orbit (LEO) satellite network. Overload is very common in LEO satellite due to the non-uniform distribution load and the periodic satellite motion. A feasible approach to realize load balancing is that the terminals (destination nodes) served by LEO satellite hand over to GEO satellite....
The university students are a special group among the users of mobile phones. Their features of pursuing fashion, self-expression, and courage in exploration take great impact on the development of mobile phones. The effect of user experience directly influences the popularity and sales volume of the mobile phones. In this paper, from the perspective of user experience, it studies the users' features...
