A Novel Stacked Cell Layout for High-Frequency Power Applications
IEEE Microwave and Wireless Components Letters, 2021 This letter presents an innovative stacked cell, where the common source device is split in to two smaller devices leading to a more compact and symmetric structure, with almost negligible parasitics associated with the transistor connection. This novel configuration is rigorously compared, for the first time, with the two classical approaches commonly

Optimal stack layout in a sea container terminal with automated lifting vehicles [PDF]
International Journal of Production Research, 2014 Container terminal performance is largely determined by its design decisions, which include the number and type of quay cranes, stack cranes, transport vehicles, vehicle travel path and stack layout. We investigate the orientation of the stack layout (parallel or perpendicular to the quayside) on the throughput time performance of the terminals ...
