Mechanical behavior of two-layer metal laminate structures under low-speed impact loading was investigated experimentally and numerically. The experimental results were just used for validation of numerical results. Then numerical modeling was used to study the behavior of metal laminates in details. The mechanical behavior of the metal laminate structures under impact loading was found to be d...

In vitro, Escherichia coli RecA protein acts upon gapped and partially homologous linear duplex DNA to generate recombination products linked by Holliday junctions. When strand exchange reactions are supplemented with purified RecBCD enzyme, we observe the formation of products that resemble "patch" recombinants. The formation of "splice" recombinant products was not observed. The individual su...

Man-made Surface Structures from Triangulated Point Clouds Photogrammetry aims at reconstructing shape and dimensions of objects captured with cameras, 3D laser scanners or other spatial acquisition systems. While many acquisition techniques deliver triangulated point clouds with millions of vertices within seconds, the interpretation is usually left to the user. Especially when reconstructing ...
