Abstract Ever new requirements for the environmental compatibility and safety of products do not stop at automotive industry. This results in ever shorter time windows pre-series processes. For this reason, time-consuming preliminary tests must be minimized to ensure an accelerated start-up production that is as trouble-free possible. maxim applies all parts automobile, but especially body shop...

In two experiments we looked at the effects of the color of equiluminant backgrounds on simple reaction time (RT) to increment and decrement spot-stimuli varying in diameter. When comparing both red vs blue and red vs green backgrounds, we found that for the smallest diameter stimuli, RTs tended to be faster with red background; however, as the diameter of the stimuli increased, RTs were faster...

Metal droplet is produced accompanied with vacuum arc discharge, which important to the research of cathode spot and application arc. The comes from crater can reflect physical process spot. However, it will destroy uniformity surface deposition in engineering should be avoided as much possible. measurement metal usually adopts off-line collector, cannot obtain signal whole space singe In order...

Protein microarrays are rapidly emerging as valuable tools in creating combinatorial cell culture systems where inducers of cellular differentiation can be identified in a rapid and multiplexed fashion. In the present study, protein microarraying was combined with photoresist lithography to enable printing of extracellular matrix (ECM) protein arrays while precisely controlling "on-the-spot" ce...

The development of new approaches in image processing and retrieval provides several opportunities in supporting in different domains. The group of welding engineers frequently needs to conduct visual inspections to assess the quality of weldings. It is investigated, if this process can be supported by different kinds of software. A generic CBIR system has been successfully used to sort welding...

A double-achromatic, double-focusing magnet system of very small size is described which will be used in the injection line for an undulator in a FEL experiment . Because of the double focusing no quadrupoles are needed between the dipole, which couples the electrons in the FEL cavity, and the undulator. An example will be worked out for an electron bunch of 25 MeV, 100 Awhich is focused on a s...

We report on new experiments and theory that unambiguously resolve the recent puzzling observation of large diameter exciton emission halos around a laser excitation spot in two dimensional systems. We find a novel separation of plasmas of opposite charge with emission from the sharp circular boundary between these two regions. This charge separation allows for cooling of initially hot opticall...
