An investigation into the loss of the Brazilian space programme's launch vehicle VLS-1 V03
There has been a rapid increase in the complexity and integration of many safety-critical systems. In consequence, it is becoming increasingly difficult to identify the causes of incidents and accidents back through the ...
The aster mission: Exploring for the first time a triple system asteroid
2001 SN263 is a triple system asteroid. Although it was discovery in 2001, in 2008 astronomical observation carried out by Arecibo observatory revealed that it is actually a system with three bodies orbiting each other. ...
Multistage Security-Constrained HVAC/HVDC Transmission Expansion Planning With a Reduced Search Space
(Ieee-inst Electrical Electronics Engineers Inc, 2017-11-01)
