It was found that the axial time-averaged liquid velocity was lower than that obtained in empty bubble columns, and that both the time-averaged liquid velocity and the RMS value of the liquid increased for the larger packing size.
In what the German philosopher Karl Jaspers called the Axial times (i. e. the 6th century BCE) the Jewish tradition in the Middle East and Buddhism in India emerged more or less simultaneously.
For a given multi-axial time history, PDMR method can be used to reliably extract the following parameters that are important for modeling multi-axial fatigue damage:.
Based on the predicted time dependent effective properties, the overall response of the composite is investigated for uniaxial and multi-axial time dependent loadings.
A gradient-echo EPI (echo planar imaging) sequence was used to collect the data from 38 contiguous axial slices (time repition = 3 s, time echo = 25 ms, field of view 28 × 28 cm, matrix size = 128 × 128, slice thickness 3 mm).
Functional data were collected using high-resolution echo planar T2*-weighted imaging (EPI, 40 oblique axial slices, time repetition [TR] 2490 ms, time echo [TE] 30 ms, in-plane resolution 2 × 2 mm, slice thickness 2 mm plus a 25% slice gap, 192 × 192 mm field of view).
We acquired 668 EPI image volumes for the carryover experiment (32 axial slices, time repetition [TR] = 2000 ms, time echo [TE] = 30 ms, flip angle [FA] = 77, 3 mm).
Based on mixed structured and unstructured finite element mesh, and using the modern CAE technology, the stress analysis and stability analysis on 360-type doubly-telescopic prop are conducted with axial 1.5 times and 2.0 times rating alignment load, off-center 0.3R 1.1 times rating load, based on full range of stroke.
