In this paper, mini-channel type evaporator which is new in mobile air conditioning (MAC) or automotive air conditioning (AAC) systems is thermally modeled. The performance of mini-channel evaporator is also compared with the laminated evaporator which is being currently used in automotive industries. The mini-channel evaporator was constructed of two rows of parallel flow mini-channel tubes...

Coherent optical systems for short-reach links have seen a boost in their popularity with the standardization of 400ZR. These need to be cost and power-efficient, while coping ever increase traffic demand. The use probabilistic constellation shaping (PCS) can help meet these demands, since it reduces gap channel capacity. However, studies concerning PCS typically include amplification; therefor...

34 LLE Review, Volume 65 A significant amount of hardware was added to OMEGA to upgrade it to a 30-kJ, 60-beam laser. To control this hardware, an entirely new control system was implemented. This article describes one of the core subsystems of that control system— the Power Conditioning Executive.1 Timing and control of the electrical energy fed to OMEGA’s amplifiers are provided by the power ...
