Initial results from a field campaign of wake steering applied at a commercial wind farm – Part 1
. Wake steering is a form of wind farm control in which turbines use yaw offsets to affect wakes in order to yield an increase in total energy production. In this first phase of a study of wake steering at a commercial wind farm, two turbines implement a

Field experiment for open-loop yaw-based wake steering at a commercial onshore wind farm in Italy
. The concept of wake steering on wind farms for power maximization has gained significant popularity over the last decade. Recent field trials described in the literature not only demonstrate the real potential of wake steering on commercial wind farms ...

Orexin and MCH neurons: regulators of sleep and metabolism
Sleep-wake and fasting-feeding are tightly coupled behavioral states that require coordination between several brain regions. The mammalian lateral hypothalamus (LH) is a functionally and anatomically complex brain region harboring heterogeneous cell ...

Anthropogenic signals recorded in an ice core from Eclipse Icefield, Yukon Territory, Canada [PDF]
Trends in the annual flux of sulfate and nitrate in a new ice core collected at an elevation of 3017 m on Eclipse Icefield, 45 km northeast of Mt. Logan were examined to determine the effect of anthropogenic activity on precipitation chemistry in the ...

Receiver Design for Realizing On-Demand WiFi Wake-up using WLAN Signals
In this paper, we design a simple, low-cost, and low-power wake-up receiver which can be used for an IEEE 802.11-compliant device to remotely wake up the other devices by utilizing its own wireless LAN (WLAN) signals.

Improving practical sensitivity of energy optimized wake-up receivers: proof of concept in 65nm CMOS
We present a high performance low-power digital base-band architecture, specially designed for an energy optimized duty-cycled wake-up receiver scheme. Based on a careful wake-up beacon design, a structured wake-up beacon detection technique leads to an ...
