A data recorder recovered from the train's rear locomotive indicated the speed at which it went off the tracks, Bella Dinh-Zarr, spokeswoman with the U.S. National Transportation Safety Board, told a news conference. (Reporting by Keith Coffman in Denver; editing by Jo...
Often, airlines and flight aggregators add a premium to domestic flights when purchased together with the international leg. On the other hand, if you book them separately, you’ll have more options across all airline alliances. Many popular routes in the US, which are the ones typically trave...
What was supposed to be a three-month trip to Guatemala, was cut short to six weeks. The reasons why I left early have little to do with the country itself, rather, it was me doing a poor job of planning this trip and making several mistakes that somebody of my tenure in this biz ...
, in the traveling mechanism, the structure is simple and reasonable, the weight is light, the cruisingability is strong, the carry is convenient, and the application of the traveling mechanism has important significance on ensuring safe operation of transmission lines and communication lines....
The performance is also assessed with the Bergeron model and the frequency dependent parameter model of the transmission line. Numerical simulations and laboratory tests demonstrate that the method can correctly identify the front-wave arrival time at each end with better accuracy and different sampling...
Furthermore, all derived results were verified by putting them back into the assumed equation with the aid of Maple software. Further, the conservation laws of NLETLs are computed by the multiplier method. Keywords: nonlinear low-pass electrical transmission lines; modified khater method; multiplier...
