Purpose The missing travel time data for roads is a common problem encountered by traffic management departments. Tensor decomposition, as one of the most widely used method completing data, plays significant role in intelligent transportation system (ITS). However, existing methods tensor decomposition focus on global structure, resulting relatively low accuracy fibrosis scenarios. Therefore, ...

In unmanned aerial vehicle (UAV)-assisted data collection system, UAVs can be deployed to charge ground terminals (GTs) via wireless power transfer (WPT) and collect from them information transmission (WIT). this letter, we aim minimize the time required by a UAV jointly optimizing trajectory of scheduling for all GTs. This problem is formulated as mixed integer nonlinear programming (MINLP) wh...
