In this paper we analyze the role of Enterprise Systems (ES) in shaping a company’s transformation process by conducting an in-depth case study in a large European high-tech company. Although there are previous studies concerning organizational transformation and ES implementation process, the role of ES as an instrument for de-institutionalization is not well understood. By drawing on the fr...

The mathematical modelling of sheet metal forming operation is extended to include information about the particular tool and the particular machine that will be used in the "real" process. Particular attention is paid to the structure and to the operation of a mechanical press. For this type of process some control factors (parameters that the engineer can set during the fine tuning of the form...

The automotive industry and research centers have intensified the search for innovative solutions in field of material technologies recently accelerated their work on thermoplastic based composites line with requirements. Thermoform method is used rapid forming thermoplastics composites. In this process, mold design especially molding parameters are important part quality. Thermoplastic composi...

Forming limit curves (FLC) of deep drawing steel sheets have been determined experimentally and calculated on the base of the material tensile properties following the Hill, Swift, Marciniak-Kuczyński and Sing-Rao methods. Only the FLC modeled from a singly linear forming limit stress curve exhibits good consistence with experimental curve. It was established that a linearized limit stress locu...

The residual stresses that occur in the machined parts after the tools removing are the main cause that determines the springback of the draw parts made from metal sheets. Hence, to investigate this instability phenomenon it must be known the state of residual stresses developed in the part by its machining. But, the experimental investigation of the residual stress distribution in the case of ...

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...

-It is generally agreed that the advantage of on-line character recognition methods with respect to off-line ones mostly relies on the availability of dynamic information. This mainly concerns the order in which the strokes forming characters have been drawn. In this paper we present and discuss a method which attempts, in the off-line case, to recover part of the lost script dynamics. The meth...
