DC bus power quality and rate-of-change in electrical generator power are compared for different energy storage system (ESS) rate-limit controller designs. The rate-limit feature enables the electrical generator(s) on a MEA to be protected from sudden load transients, which is anticipated to red...
Summary Phase change materials (PCMs) are widely used in new energy storage fields such as industrial waste heat recovery and solar heat recovery. However, the low thermal conductivity of PCMs causes the slow heat storage efficiency of PCMs, resulting in a large waste of waste heat. For the ...
challenges around work and schooling. Some of us found it easier than others to adapt our routines to do many activities from home.4Others, however, struggled and eventually became more inflexible in their thinking. They stuck to the same routine activities, with little flexibility or change. ...

Furthermore, for an (NVT) ensemble we have(6)S/kB=lnQ+U/Twhere U is the system's internal energy, which allows us to replace Qa/Qg = eSa/kB under the condition that the process is isothermal and the total energy of the system does not change during a particle jump, which is ...

Present-day sea-level rise is a major indicator of climate change1. Since the early 1990s, sea level rose at a mean rate of ∼3.1 mm yr−1 (refs 2, 3). However, over the last decade a slowdown of this rate, of about 30%, has been recorded4,5,6,7,8. It coincides with a...

Note that the entropy change of this extended system is also zero since the state of air does not change at any point during the process. The difference between the two entropy generation rates is 0.150 W/K, and represents the entropy generation rate in the air layers on both sides of the...
