Based on the approach of the 'social shaping of technology', this paper will provide a brief discussion of a) the impact that the individuals who populate a standards body's working group, and b) this body's voting rules have on its final standards. It will primarily draw upon a qualitative empirical study. In particular, this paper will use the IEEE 802.11 group as a real-world sample group to further highlight the issues discussed more theoretically above.

To meet the challenge of producing innovative and technologically demanding products economically, companies need the ability of quick and flexible reaction to internal and external disturbances. Increased performance of a company can be achieved by focusing on improvements to effectiveness and efficiency;principal tasks of modern quality management. Quality management itself must not only face new entrepreneurial challenges;its main task remains consistently providing information for continuous improvements. Based on a new definition of quality, a framework is introduced that faces the entrepreneurial conditions from quality management's point of view and provides an organizational element, which assists in meeting the demand for informational transparency. this element, the quality backward chain, which is responsible for providing the needed information, is then introduced. By means of a modular conception on the operative and the adaptive levels, the backward chain acts as a quick and flexible organizational controller for entrepreneurial quality.
Moving mesh methods are becoming increasingly popular for several kinds of parabolic and hyperbolic partial differential equations (PDEs). In this paper, we develop a moving mesh method based on minimizing energy func...

Two-terminal series parallel (TTSP) graphs are used as data models in applications for electric networks and scheduling problems. A TTSP graph with an efficient data structure enables us to design efficient strategies for solving such problems. In 2005, Ferragina et al. presented an xbw representation and an xbw transform for an edge-labeled ordered tree, which is a data model of tree-structured data such as Web pages. First, we give a novel succinct representation of a TTSP graph as a sequence of xbw representations of ordered trees. Second, we present a linear time algorithm as a succinct data transform of a TTSP graph. third, we present an efficient path search algorithm, which uses a succinct representation of a given TTSP graphs as its data structure, for finding all occurrences of paths of a given string. Finally, we report preliminary experimental results that demonstrate the performance of our algorithms.

Such topics as smart home, smart car have become widespread recently. the paper presents an innovative approach to context-oriented knowledge management in the smart space. the smart space consists of a set of devices that can interact with each other, exchange information and services. Knowledge management in such systems allows coordinating activities of a large amount of entities which can communicate within the smart space.

Given an efficient process, five-axis milling is a productive technology that can help production industries in countries with a high level of workers' wages to remain competitive on the global market. For planning the required machining processes, engineers have to be supported by methods and tools. In current research at WZL of RWth Aachen and IPT of Fraunhofer Gesellschaft, a CAx framework for simulation-based planning of complex machining processes is developed. this software tool, embedded in a CAM system, bases on coupled models of numerical controllers, machine tools, control loops and cutting processes. For supporting an iterative optimization without long computational times, the optimization concept focuses on the identification of critical areas in NC programs regarding effects of different domains (e.g. control, machine, and process). these effects can be determined by applying a sensitivity analysis in combination with tracing tools, as it is exemplarily presented for NC effects.

Product quality lies in the eye of the beholder. It is an individual and subjective interpretation of realized product criteria and hence more than the compliance withthe customer's expressed performance requirements. But the elicitation of delighting quality attributes is both time- and cost-intensive and often still open to interpretation. To successfully differentiate themselves from their competitors, companies have to systematically objectify their customers' quality judgments. the paper presents an integrated approach to structure quality perception from the customer's perspective and to channel the relevant information into the product development process. Key elements are the coordinated survey and specification of perception-relevant product attributes to minimize losses and misinterpretations. this supports the change from an intuitive to a fact-based product development as well as the notion of a resource-conserving value chain.
