Now, a full-body musculoskeletal simulator for swimming has been developed for the AnyBody Modeling System, which enables to calculate fluid force acting on the whole body during swimming. The model presents 4 swimming styles: Crawl, Breststroke, Backstroke, and Butterfly.
The average cost for a domestic flight is up 4.5 percent from a year ago, to $399.48, based on data from Travelocity.com. An international ticket is about 2.3 percent more expensive than a year ago, at $991.82.
What's more, researchers found that average ticket prices were fairly flat during the window of time 50 to 100 days before departure. In other words, the best bet is to book 50 to 100 days beforehand: Tickets purchased during that period were $85 cheaper than the overall average for all domestic flight prices ($495.55).
