    Development of schlieren-image based flow diagnostics and analysis for supersonic jet flows by Lim, Desmond Haoxiang

    Published 2020
    “…The technique was applied to over-expanded baseline and 30° bevelled jets with the results agreeing well with earlier studies. When compared against PIV results, the much higher spatial and temporal resolution of SIVOF resulted in sharper and clearer vortical structures that can be tracked across several time-resolved frames. …”

    The sensitivity of tsunami models and tsunami energy to geologically constrained fault sources and shallow bathymetry by Felix, Raquel Picar

    Published 2023
    “…The choice of specific resolu-tion should also depend on the mean distribution of data points, so that most of the data are represented well in the interpolated bathymetry. The use of publicly avail-able coarse-resolution dataset such as GEBCO, however, will lead to highly unreliable estimations of tsunamis at the coast. …”

    Effects of positive education approach on academic boredom, intrinsic motivation, positive emotions and thought-action repertoire among private college students in Shaanxi Province... by Jie, Zheng

    Published 2022
    “…There were no statistically significant differences in the mean scores of LRB, CRB, IM, PE, and TAR from pre-test to post-test (p .01); the PEA was much better than the TEA in reducing students’ academic boredom (LRB, CRB) and improving their wellbeing (PE, TAR) as well as academic success (IM) (p .01). An examination of the mean scores indicated a significantly lower level of LRB in the experimental group (M=22.00, SD=7.59) than in the control group (M=31.11, SD=8.28) (p .01); a significantly lower level of CRB in the experimental group (M=21.14, SD=7.24) than in the control group (M=31.17, SD=9.40) (p .01); a significantly higher level of IM in the experimental group (M=62.52, SD=12.07) than in the control group (M=54.30, SD=14.35) (p .01); a significantly higher level of PE in the experimental group (M=28.43, SD=6.29) than in the control group (M=25.51, SD=5.41) (p .01); a significantly higher level of TAR in the experimental group (M=9.27, SD=5.70) than in the control group (M=5.48, SD=4.01) (p .01). …”
