Abstract Sheet metal formed parts are often produced in multistage processes. The multi-directional deformations that occur this process pose a challenge for sufficiently accurate modeling of the material behavior. In paper, we present an experimental methodology and its potential serves as basis comprehensive validation models with respect to deformation. Therefore, results pre-strained DP600 ...

The spaceborne ESA-mission CHRIS (Compact High Resolution Imaging Spectrometer) on-board PROBA-1 (Project for On-board Autonomy) delivers multi-directional data sets that contain spectral, directional, spatial and multi-temporal information. CHRIS/PROBA data have been acquired over two well documented test sites in Switzerland (Swiss National Park (SNP) and Vordemwald (VOR) since 2003 and allow...

A major component of 3D design involves the manipulation of curved surfaces or the complex triangle meshes which approximate them. In the specific case of land-use planning design, these surfaces often represent the underlying terrain. Many techniques exist for the deformation of terrain surfaces for a single user. Building on existing work in the use of laser pointers for shared display groupw...

During an earthquake, structures are subjected to both horizontal and vertical shaking. Most structures are rather insensitive to variations in the vertical acceleration history and primary considerations are given to the impact of the horizontal shaking on the behavior of structures. In the laboratory, however, most component tests are carried out under uni-directional horizontal loading to si...

It is shown that the throughput capacity of wireless ad hoc networks using omni-directional antennas (OMN networks) is significantly decreased with the increased number of nodes. One major reason lies in the interference caused by using omni-directional antennas, which just broadcast radio signal in all directions. Thus, a communication with multiple short-ranged hops is suggested in such netwo...

We use stroboscopic quantitative phase microscopy to study cell deformation and the response to cavitation bubbles and transient shear stress resulting from laser-induced breakdown of an optically trapped nanoparticle. A bi-directional transient displacement of cytoplasm is observed during expansion and collapse of the cavitation bubble. In some cases, cell deformation is only observable at the...
