This paper reports results from a study on the adoption of an information visualization system by administrative data analysts. Despite the fact that the system was neither fully integrated with their current software tools nor with their existing data analysis practices, analysts identified a number of key benefits that visualization systems provide to their work. These benefits for the most p...

We present a constructive stabilization algorithm for a particular class of driftless control aane systems. The algorithm makes systematic use of homogeneity, Lie brackets of vectorrelds and Lie algebraic properties , and the resulting feedback laws are periodically time-varying.

It is no secret that the importance which evaluation has acquired, lately, in the educational world is of primary magnitude. However, examinations can also be used for learning, especially if collaborative learning activities can be integrated into them. We present a collaborative evaluation technique we have used as well as the software tool we have designed in order to deal with the problems ...

This paper presents TagCare as a tool which allows users to maintain their personal tagging vocabulary and to carry it along different platforms. TagCare collects the tags which a user has applied within several social software tools. These personal tags may be edited and structured, e.g. interrelated with hierarchical and other semantic relations.

A rapidly deployable manipulator system combines the flexibility of reconfigurable modular hardware with modular programming tools, allowing the user to rapidly create a manipulator which is custom-tailored for a given task. This article describes two main aspects of such a system, namely, the Reconfigurable Modular Manipulator System (RMMS) hardware and the corresponding control

During the manufacturing planning, multiple variants of process chains for the manufacturing of a product to be developed are generated by engineers. In order to select an optimal variant, multiple decision criteria specifying technical, ecological and economical properties of the process chains as well as multiple assessments of different domain experts have to be taken into account. The contr...

The book is arranged in a logical sequence covering the development of project management, project management structures, aspects of planning, monitoring and control, economics and value management, design management, intellectual property issues and production start-up. Particular emphasis has been given to risk management which is recognized as both a difficult subject and also one of growing...

In this paper we propose anti surge controllers for a close coupled valve in a compression system. The valve modifies the characteristic of the compressor, and allows for stable operation beyond the original surge line. The design tool used is backstepping and global uniform asymptotic stability is proven. Damping terms are included in the controllers, and in the presence of both mass flow and ...
