Land-sharing logging is more profitable than land sparing in the Brazilian Amazon

Environmental Research Letters, 2021
Selective logging is pervasive across the tropics and a key driver of forest degradation. Two competing harvest management strategies have been proposed: Land sharing via low-intensity logging throughout a concession; and high-intensity land-sparing ...

A low-cost directional log periodic log spiral antenna [PDF]

2010 IEEE Antennas and Propagation Society International Symposium, 2010
The Square Kilometer Array (SKA) derives its name from its total aperture area, predominately achieved by thousands of parabolic dishes, each with an antenna feed situated at its focal point. The type of antenna feed selected for SKA operation in the 1 GHz to 10 GHz frequency range, referred to as a Wide Band Single Pixel Feed (WB+SPF) [1], has drawn ...

Adaptive Logging [PDF]

Proceedings of the 2016 International Conference on Management of Data, 2016
By maintaining the data in main memory, in-memory databases dramatically reduce the I/O cost of transaction processing. However, for recovery purposes, in-memory systems still need to flush the log to disk, which incurs a substantial number of I/Os. Recently, command logging has been proposed to replace the traditional data log (e.g., ARIES logging) in
