Enhancement of Voltage Stability by Using SVC for 30-Bus Power System by Dara Hama Amin

“…Voltage stability refers to maintaining the value of the voltage in all busses of the electric network at a steady level (initial operating point) during any sudden disturbance. Voltage instability may happen due to an increase in the demand of the load or in case of any change in the reactive power, thus, the system will go into uncontrollable and unstoppable decline in the voltage level. …”

Influence of Potting Radius on the Structural Performance and Failure Mechanism of Inserts in Sandwich Structures by Filippos Filippou, Alexis Τ. Kermanidis

“…Larger potting radii also led to reduced displacement at failure, increased ultimate loads, and elevated stiffness, which were maintained until sudden structural failure. Through detailed isolation and observation of each failure event and with the use of AE data, precise identification of system damage in real time was allowed, offering insights into the progression and causes of failure.…”
