The systems of non-destructive control have been widely practiced in science and industry. This paper focuses on the development of the technique of detection and localization of differences on the images of printed circuit boards, which is achieved by comparing of the images with the reference ones.
We report an ultra-rapid prototyping technique for forming microchannel networks for lab-on-a-chip applications, called masters on-demand. Channels are produced by replica molding on masters formed by laser printing on flexible copper printed circuit board (PCB) substrates. Masters of various designs and dimensions can be individually or mass produced in less than 10 minutes. Using this techniq...
As more and more systems used in our everyday life develop to be automated, humans assume less direct control of the system and its components. Therefore, humans usually act in a monitory behavior in many complex environments, and based on certain thresholds they establish action behaviors. A key issue in the context of supervisory control is human trust in automation, which has gained an incre...
One of the major obstacles in developing high quality content for learning is the substantial development cost and effort. In addition, the return on investment is often low, as developed learning materials are difficult to reuse and adapt to new and different educational contexts. In this paper, we present a semi-automatic content assembly methodology to automate, at least partially, the reuse...
A growing need exists for electrical interconnect analysis ( E I A ) fo r chips, packages and printed circuit boards. I n this short tutorial we review key issues regarding EIA for V L S I parasitic circuits. W e give a general introduction of important aspects for technologies with different performances and then we review some issues of concern fo r state of the art high performance chips and...
