Because of the sparse distribution of the orbiting debris through the fence in our observations, we formulate the signal detection and the motion parameter estimation as a sparse signal reconstruction problem with respect to an over-complete dictionary.
The drag-induced gradual decrease in orbit altitude of the Hitomi fragments will cause these objects to pass through the orbit regime of other, low-orbiting spacecraft, whereby new close conjunctions may occur.
"The meteors are formed when the Earth passes through the orbit of the Swift-Tuttle comet," explains Professor Ian Morison, astronomer at the Jodrell Bank Observatory.
Most meteor showers are known or believed to be associated with active or defunct comets; they represent Earth's passage through the orbits of these comets and its collision with the streams of debris (typically of sand-grain to pebble size) that have been left behind.
In this paper, we study monomial representations of Lie groups through the orbit method.
and cannulation of the trachea, the 135 rats were pithed by inserting a stainless steel rod through the orbit and foramen magnum, and down the vertebral foramen [17].
The main contribution of this study is to propose a novel optimization method, Electro-Search algorithm, based on the movement of electrons through the orbits around the nucleus of an atom.
and cannulation of the trachea, all rats were pithed by inserting a stainless steel rod through the orbit and foramen magnum and down the vertebral foramen, as previously reported [18, 19].
After anaesthesia with ether and cannulation of the trachea, the rats were pithed by inserting a stainless-steel rod through the orbit and foramen magnum into the vertebral foramen [22].
For instance, every year skywatchers can spot the Perseid meteor shower as Earth moves through the orbit of comet Swift-Tuttle.
