Autor: ZHANG NingNing, PAN YingLi, GENG SenLin

Publikováno v: Jixie qiangdu, Vol 38, Pp 1178-1183 (2016)

Ladder type disc acoustic radiator is widely used in high power ultrasonic field. The frequency equation of stepped thickness disk in free boundary condition are derived based on Mindlin theory from the acoustic point of application and The frequency

Cheminės sudėties tyrimas Galaktikos žvaigždžių substruktūrose

Autor: Ženovienė, Renata

Helmi et al. (2006) identified three new coherent groups of stars in the Geneva-Copenhagen survey (GCS) (Nordström et al. 2004) and suggested that those might correspond to remains of disrupted satellites. In this dissertation work we investigate de
