FFT-perustainen spektrianalyysi USRP-ohjelmistoradioalustalla

, 2020
Tiivistelmä. Tässä työssä tutustutaan tehotiheysspektrin estimoinnissa käytettyihin menetelmiin ja käytetään USRP-2900 ohjelmistoradiota spektrianalysointiin. Mittauskaistaksi valittiin WLAN-kaista, mutta työssä käytetyllä menetelmällä voi suorittaa mittauksia myös muilla kaistoilla. Työssä käytetyllä menetelmällä mittaus voidaan tehdä kaistalta, jonka

Thermal-mechanical coupled regulation of Ti-22Al-25Nb/Ti-6Al-4V bimetallic structures during an alternating ultrasonic surface rolling – laser directed energy deposition hybrid process

Virtual and Physical Prototyping
Although bimetallic structures have demonstrated great thermomechanical compatibility under extreme temperature gradients, the poor bonding performance and damage resistance still hinder wider application. In this study, an alternating ultrasonic surface
