A more realistic assessment of beach effects of 2880 March 16 asteroid impact tsunami
Eight years ago, some scientists computed for a 1.1-km diameter asteroid (1950 DA) a 0.0 to 0.3 per cent probability for colliding with Earth. Not long after this, a quasi-analytic model for wave propagation was used to describe the dynamics of the tsunami generated by the asteroid impact somewhere at 600 km east of the U.S. coast. Starting from the same initial conditions, our paper resumes th...
متن کاملAsteroid 1950 DA's encounter with Earth in 2880: physical limits of collision probability prediction.
Integration of the orbit of asteroid (29075) 1950 DA, which is based on radar and optical measurements spanning 51 years, reveals a 20-minute interval in March 2880 when there could be a nonnegligible probability of the 1-kilometer object colliding with Earth. Trajectory knowledge remains accurate until then because of extensive astrometric data, an inclined orbit geometry that reduces in-plane...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
