The paper presents an application of a variance decomposition method for the sensitivity analysis of the thermal hydraulic (TH) model of the Passive Containment Cooling System (PCCS) of an Advanced Pressurized Reactor (AP1000). The Loss Of Coolant Accident (LOCA) is considered as the most representative accident for identifying the Failure Damage Domain (FDD) of the PCCS with respect to the ind...

We consider a wide family of optical coherent feedback loops acting on an optomechanical system operating in the linearized regime. assess efficacy such improving key operations, as cooling, steady-state squeezing and entanglement, well optical-to-mechanical state transfer. find that mechanical sideband cooling can be enhanced through passive, interferometric feedback, achieving lower occupanci...

Passive solar system design is an essential asset in a zero-energy building perspective to reduce heating, cooling, lighting, and ventilation loads. The integration of passive systems leads reduction plant operation with considerable environmental benefits. can be related intrinsic extrinsic factors that influence the final performance synergistic way. aim this paper provide comprehensive view ...

Passive cooling for thermal comfort improvement has received extensive attention its low energy consumption. However, most of the existing passive technologies require a complex system design and supporting equipment, since they cool ambient air. Herein, we propose hybrid evaporative radiative membrane with hygroscopic hydrogel sandwiched by two layers porous polyethylene aerogel (PEA). The imp...
