The purpose of introducing ultrasonic vibrations in the tube hydroforming process is to create more formability by obtaining a lower corner radius, improve thickness distribution of the wall and provide good tribological conditions at the tube and the die interface. Vibrations imposed on the die create alternating gaps which improve the formability in the tube hydroforming process in the presen...

In this paper, we present boundary labeling, a new approach for labeling point sets with large labels. We first place disjoint labels around an axis-parallel rectangle that contains the points. Then we connect each label to its point such that no two connections intersect. Such an approach is common e.g. in technical drawings and medical atlases, but so far the problem has not been studied in t...

Reading a book is also kind of better solution when you have no enough money or time to get your own adventure. This is one of the reasons we show the machine interpretation of line drawing images technical drawings maps and diagrams as your friend in spending the time. For more representative collections, this book not only offers it's strategically book resource. It can be a good friend, real...
