Warming as well as species introductions have increased over the past centuries, however a link between cause and effect of these two phenomena is still unclear. Here we use distribution records (1813–2023) to reconstruct the invasion histories of marine non‐native macrophytes, macroalgae and seagrasses, in the Mediterranean Sea. We defined expansion as the maximum linear rate of spread (km year−1...
This paper investigates by experiment and simulation the use of the real-time measurements of on-state voltage VCE(ON) and threshold voltage Vth for real-time health monitoring of IGBT power modules. A study of the dependencies of each parameter on temperature, wear-out mechanisms and operating conditions is presented. Online measurement circuits are developed to obtain these two parameters during...
Reliable functioning of a power electronic switching device is limited not only by the instantaneous device junction temperature but also by its variation. A technique for reducing the device temperature variation is described. A simplified mathematical model of the thermal process in the device is evaluated in real time to estimate the instantaneous device temperature. A temperature control loop...
