Mechanism of microstructure and mechanical properties improvement through ultrasonic rolling pressing layer-by-layer and adaptive ultrasonic rolling method research in AlSi10Mg laser powder bed fused

Journal of Materials Research and Technology
In the process of laser powder bed fusion (L-PBF), the high-speed movement of the laser heat source causes uneven temperature and stress fields, thus, it results in dendrites, pores, micro cracks and residual stresses.

Energy detection spectrum sensing measurement using GNU radio and USRP B200 at Wi-Fi frequency

, 2015
Spectrum sensing is one of the main tasks of cognitive radio, it decides whether the spectrum band is occupied by the primary or not. One of the techniques of spectrum sensing is energy detection (ED).
