Situational awareness of Earth-orbiting particles is highly important for future human activities in space. For optical observations of debris, multiple observations must be combined in order to determine the orbit of the observed object. It is generally uncertain, however, whether two arbitrary tracks are of the same object, and solving this problem can be computationally intensive. In this pa...

the problem of scheduling with multi agent has been studiedfor more than one decade and significant advances have been madeover the years. however, most work has paid more attention to the conditionthat machines are available during planning horizon. motivatedby the observations, this paper studies a two-agent scheduling modelwith multiple availability constraint. each agent aims at minimizing ...

The subspace-based estimation of direction of arrivals (DOAs) of multiple sound sources requires multiple observation data from a microphone array, such that basis of signal subspace can be fully identified. For coherent sources, however, multiple measurements only produce linearly dependent observations, which makes it difficult to separate signal subspace from noise subspace. In order to obta...
