Dynamic Channel Calibration on a Crystal-Free Mote-on-a-Chip
IEEE Access, 2019 The single chip integration of a wireless sensor node would allow for cheap, low-power, dust-size devices. The key to realizing this vision is to eliminate bulky off-chip frequency references such as crystal oscillators or resonators, and their ...

An extended actuator cylinder model: Actuator‐in‐actuator cylinder (AC‐squared) model [PDF]
Wind Energy, 2019 AbstractIn this paper, the actuator‐in‐actuator cylinder (AC‐squared) model is presented. This model is an extension of the original actuator cylinder model of Madsen and is capable of modelling the effect of a two concentric actuation surfaces in 2D. The induced velocity at every point in the 2D field is affected by the force field acting on the two ...
