考虑支承跨距的非线性转子系统动力学特性研究 by 李辉, 管洪杰, 邵凤翔, 刘希东

“…According to the geometric model of spindle deformation,the total displacement relation of the front end of the spindle is obtained,and the optimum bearing span of the spindle is determined according to the minimum displacement of the front end.By means of numerical integration,the nonlinear dynamic response of the rotor system with the optimal span support is given,and the influence of rotational speed on the system dynamic response is analyzed by using axial trajectory diagram,phase portraits and Poincaré map.The results show that the rotor bearing system has good stability when it is running under the optimum support span.…”

Sexualitet, samtycke och relationer i grundskolans bildämne by Elisabeth Lisa Öhman

“…More specifically, it explores how phenomena such as identity, sexuality, and gender are material—discursively produced during 15–16-year-old students’ work with photographic portraits in Arts education in Grade 9. Using Karen Barad’s concept of space-time-matter in the analysis shows how subject-didactic opportunities and challenges reformulate the ideas about what sexuality education can be. …”
