We propose a multi-directional triangulation optical system and scanning exposure method for precise height displacement measurement of metal-works.
Differences in total duration of hopping (1-way repeated ANOVA) and dependant variables for the start and end periods (2-way repeated ANOVA) including duration of flight (tf), loading (tl) and contact (tc) phases, vertical height displacement during flight (zf) and loading (zl) phases, normalised peak vertical ground reaction force (FzN) and normalised vertical stiffness (kN), were determined.
Description: If the friction between buffer discs increases due to high pressure and if there are large height displacements of touching buffers an overriding of these buffers might occur.

The analyzed columns revealed a good agreement with the experimental results with an average difference of 16% and 17% for column ultimate load and mid-height displacement respectively.
The second part is analytical analysis using nonlinear finite element program ANSYS11 on nineteen columns (ten tested square columns and nine rectangular section columns) to study the effect of the previous parameters on the column ultimate load, mid-height displacement, and column cracking patterns.
Murata et al. performed a study of 109 patients with low back pain and/or sciatica by analyzing lumbar disc height, horizontal displacement, and angular displacement on plain radiographs, and comparing these findings with disc degeneration on MRI [ 5].
Both height and displacement images were captured at field widths of 50, 25, 10 and 5 μm.
Several key modeling considerations, including girder web distortion, the idealization of the cross-frames, support and load height, and displacement compatibility between the girders and slab, are addressed.
Prior to reporting on these non-linear analyses, Eigenvalue FE analyses are used to establish the influence on resistance of changing load height or displacement boundary conditions.
As seen from Fig. 12, with the increase of beam height, the vertical displacement of rail, irregularity versine, and alignment value, and PSD all decrease.
