However, sufficiently accurate distances for back-analyses of the experiment could not be obtained due to measurement uncertainties.
Systematic monitoring of the rock deformations due to tunnelling can help to define the most adequate support measures and to improve the input values for static calculations by back analyses.
This study presents a nonlinear optimization technique (NOT) for conducting the back analyses of geotechnical engineering problems based on the field observations.
As shown in Fig. 13, Dan3D-Flex enabled a simple parameterization of basal resistance, comparable to that used for previously successful back analyses of rock avalanches.
The discussion starts by identifying structures and flows of forward and back analyses; and it is then expanded to cover several back analysis procedures, including application examples, formulated for linear and non-linear material behaviors.
The three back analyses demonstrate that the accuracy of rock avalanche runout models can be greatly improved by accounting for the initially rigid phase of motion.
For the knock-back analyses, we digested about 200 ng (1 μl) of genomic DNA with SmaI at 30°C in a final volume of 20 μl for 6 hours according to the manufacturer's directions (Fermentas).
Tables 3 and 4 show results of the initial univariate logistic regression analyses for back and lower extremity pain limiting work ability, specified for individual and rated health (table 3) and work-related variables (table 4).
Here we describe two rock avalanches in the Rinderhorn area of the Bernese Alps, Switzerland, providing new mapping of rock avalanche source areas and deposits, refined volume estimates for each event, runout modeling back-analyses, and absolute age constraint from cosmogenic 36Cl surface exposure dating.
All presentations with the triage code for back pain were extracted and analysed.
Presentations where the triage nurse selected the triage code for "back pain" were extracted and analysed.
