Edge casing is a well-known method to improve the readability of drawings of non-planar graphs. A cased drawing orders the edges of each edge crossing and interrupts the lower edge in an appropriate neighborhood of the crossing. Certain orders will lead to a more readable drawing than others. We formulate several optimization criteria that try to capture the concept of a “good” cased drawing. F...

In this paper we study weak proximity drawings All known algorithms that compute weak proximity drawings produce representations whose area increases exponentially with the number of vertices Additionally an exponential lower bound on the area of weak proximity drawings of general graph has been proved We present the rst algorithms that compute a polynomial area proximity drawing of binary and ...

Due to the spread of mobile handheld devices, new application fields like technical maintenance and mechanical inspections open up to their use. Yet, to fully benefit from their modern technical capabilities, standard interaction techniques need to be revised and new ways of accessing the abundance of technical documentation on the handheld need to be conceived. However, the display of technica...

We use patent citation networks to study the dynamics of technical change in Ethernet, a standard for data communication. We first consider the evolution of the broad technological system of Local Area Networks (LANs) and we identify the most significant inventions within the specific subfield of Ethernet. Then we analyse the structure of connectivity of patent citation networks to reconstruct ...

Due to the benefits associated with Agile practices, such as flexibility, responsiveness. Large-scale software companies have been attracted to scale Agile practices which has led to software vices like technical dependencies. This study investigates the challenges associated with technical dependencies, and the challenges of communicating technical dependencies in large-scale Agile software de...

This paper presents an application that helps to index archives of technical drawings. Indexing consists in extracting information from the title block in order to ensure document retrieval in a database. The indexing information is usually the drawing number and the title. Today, indexing is mostly done manually. By describing the variability of technical drawing forms, this paper explains why...
