Variable, full?scale tester for tunnel linings

چکیده
This contribution presents a new tester for tunnel lining segments in the final serviceability load stage. It aims to concentrate resources of testing laboratories on single segment capturing most real conditions present tunnels. Its variability is presented, that is, geometrical and mechanical configurations it can adapt to. performance validated by means prototype test conventionally reinforced segment. Horizontal vertical loads are applied simultaneously simulate similar loading as To this end, three hydraulic cylinders coupled, so forces up 5 MN both directions be applied. The external introduced radially semi-distributed manner at eight different points extrados. kinematics recorded show proper distribution specimen. Moreover, brings into light its weak spot, longitudinal joint.

An Image-Based System for Change Detection on Tunnel Linings
We present an automated system for detecting visual changes on tunnel linings. By registering new images to a three-dimensional tunnel surface model, recovered using Structure and Motion techniques, we are able to detect and localise changes accurately in order to assist visual inspection by a human expert. We formulate the problem of detecting changes probabilistically and exploit different fe...
متن کاملBhopal: No Silver Linings
In the November 2003 issue of EHP, Liu et al. (2003) concluded that " relatively low concentrations of gaseous air pollutants are associated with adverse effects on birth outcomes. " Although this may be true from a purely statistical sense, there appear to be limitations of this research that suggest cautious interpretation of the findings. Liu et al. (2003) evaluated individual-level birth ce...
متن کاملSilver linings for patients with depression?
Depression has become one of the biggest health problems globally, but in certain places more than in others, suggesting cultural as well as biological causes. Neuroscientists are only beginning to understand underlying processes and to develop effective treatments for those cases where conventional psychotherapy and drugs fail.
متن کاملLearning from silver linings
The cardinal goal of decision neuroscience is to identify the neural mechanisms that translate external rewards into an internal sense of value (Rangel et al., 2008; Huettel, 2010; Glimcher, 2011; Rangel and Clithero, 2012). The brain region most commonly associated with “reward” has been the ventral striatum (vStr, neurosynth.org forward inference, 1/2013). Studies of fMRI activation and neuro...
متن کاملFAILURE MECHANISMS OF REFRACTORY LININGS FOR NONFERROUS FLASH SMELTING FURNACES
Although the flash smelting technologies use different furnace designs, the refractory linings are exposed to very similar aggressive environments and, as a result, the corrosion analysis results on one type of furnace could be generally applied to other furnaces of similar high temperature processes. Particularities regarding the different chemistries of the pyrometallurgical process and opera...
