Multi-State System Modeling and Reliability Assessment for Groups of High-speed Train Wheels
Reliability Engineering & System Safety, 2020The polygonization of high-speed train wheels is commonly considered as a serious threat to reliability of high-speed trains all over the world. Traditional studies in polygonization of wheels focus on modeling its mechanism via physics-based models ...

Something strange and old lurks under the ice in Antarctica, at a place called Blood Falls. It is an echo of the early Earth. Blood Falls is hard to reach and easy to find. Look through the seas of blue ice, white snow, and gray rocks for the bright-red frozen waterfall, spilling out of the ice around it in a gory cascade five stories tall.

The author criticizes journalists who have reported that automobiles have been "hacked" by individuals who then take remote control of the vehicle. He notes that such reports fail to accurately describe how such incidents occurred in controlled environments by researches, stating that actually hijacking such technological innovations is difficult and ...
