Future mobile networks are expected to be complex heterogeneous systems. On the one hand this will enable users to take advantage of a number of different access technologies. On the other hand it will seriously affect network management procedures since more extensive operations and decisions will have to be dealt with. To tackle these challenges a number of new dynamic mechanisms need to be designed. It is imperative that certain network management tasks have to be performed without human intervention to reduce the OPEX costs and achieve faster responses in different events. To achieve this goal, the introduction of self-x functionalities, combined with cognitive mechanisms and the ability to reconfigure network entities and terminals, is required. Moreover, the introduction of a new pilot channel needs to be considered to assist the terminals in selecting the most suitable radio access technology according to their requirements. We present the functional architecture of an evolved network that was designed in the context of the EU-funded IP project âE3: End-to-End Efficiencyâ. This architecture aims to enhance existing procedures usually performed in traditional operation and maintenance systems (e.g. spectrum management, network planning, configuration actions). We explain the rationale of our design and provide specific examples to illustrate the role of the different functional entities and their interfaces. A considerable part of this architecture has recently been approved as a feasibility study by the ETSI Committee Reconfigurable Radio System.

The objective of this paper is to analyze economic efficiency considerations of standards competition, in order to thereby enrich the discussion about the transfer of the ECMA-376-1 (Office Open XML OOXML) standard into the ISO/IEC 29500:2008 standard parallel to the already existing ISO/IEC 26300:2006 (Open Document Format for Office Applications ODF) standard. Based on the available economic literature we identify parameters that need to be considered in the decision for or against a competition between competing standards. The characteristics in the specific case of competition between the ODF and the OOOXML standard clearly justify the decision for two documents standards.

This paper investigates the application of the Delphi methodology for the identification of future fields of standardisation complemented by a methodological extension by using various science and technology indicators. By the term standardisation, we broadly mean the process of developing and implementing technical standards within a standardisation body. Underlining the explorative nature of this paper, we describe the process of identifying future fields of standardisation. To provide a systematic forecasting view on complex science and technology fields, a combination of quantitative indicator-based analyses and qualitative in-depth Delphi surveys is choosen. Firstly, statistical analyses of suitable indicators are used to identify dynamic developments in such fields. Secondly, to identify detailed challenges for future standardisation, qualitative Delphi surveys are conducted. To collect and evaluate relevant issues the respective expert communities were included. They were identified by using information derived from the science and technology databases used. The paper concludes with the assessment of the chosen approach and give practical insights for its feasibility based on a review of the existing literature on the Delphi methodology. In addition, an outlook for further improvements and other possible fields of application is given.

The paper describes a methodology for standardisation foresight developed for the German Institute for Standardisation (DIN), to systematically identify innovative standardisation topics by involving the science and research community. Up to date, formal standardisation bodies have not undertaken systematic efforts to conduct these kinds of forecasting studies. This approach identifies future standardisation aspects in dynamic, innovative fields of technology by combining a computerised quantitative analysis of science and technology indicators (e.g., patent applications, scientific publications, etc.) and Delphi-based surveys. We first describe the function and economic effects of standards in the innovative process. Then, we introduce an indicator module to identify future fields of standardisation and combine this qualitative analysis with an online Delphi survey. To illustrate the general methodological approach, we exemplarily display major results on nanotechnology. We conclude by assessing the application of our standard foresight approach and its extensibility towards computer-aided information retrieval.

Der Beitrag reflektiert die Einführung und Etablierung eines unabhängigen Qualitätsmanagements im Projekt "P23R | Prozess-Daten-Beschleuniger" im Rahmen des IT-Investitionsprogramms der Bundesregierung.

Future processing, storage and communication services will be highly pervasive: people, smart objects, machines and the surrounding space (all embedding devices such as with sensors, RFID tags etc.) will define a highly decentralized cyber environment of resources interconnected by dynamic networks of networks. As communications will extend to cover any combination of \\\people, machines and things\\\, future networks will be increasingly complex and heterogeneous, yet always endorsed with the challenging task of ensuring end-to-end QoS. This paper proposes the groundwork for an advanced cognitive networking paradigm exploitable in future wired and wireless infrastructures: a decentralized cognitive plane to allow for cross-layer, cross-node and cross-network domain self-management, self-control and self-optimization, while being compatible with legacy management and control systems.

The Carneades software system provides support for constructing, evaluating and visualizing arguments, using formal representations of facts, concepts, defeasible rules and argumentation schemes. This paper illustrates features of Carneades with a prototype legal application for analyzing open source software license compatibility issues in particular cases. The Carneades system provides a unique combination of features that make to our knowledge applications of this kind possible for the first time.

This paper presents a formal model that enables us to define five distinct types of burden of proof in legal argumentation. Four standards of proof are shown to play a vital role in defining each type of burden. These standards of proof are defined in a precise way suitable for computing in argumentation studies generally, but are based on a long tradition of their use in law. The paper presents a computational model based on these notions that represents a dialectical process that goes from initial claims where issues to be decided are set, and produces a justification for arriving at a decision for one side or the other that can withstand a critical evaluation by a particular audience. The role of the audience can be played by the respondent in some instances, or by a neutral third party audience, depending on the type of dialogue. The paper builds on previous work (Gordon, Prakken and Walton, 2007; Gordon and Walton, 2009) that has applied the Carneades model to studying burden of proof in legal argumentation.

The lecture introduces standardization as a strategic tool in the economy and society, e.g. reducing barriers to trade, for the marketability of innovations and relieving governmental regulation. The relationship between standards and patents and the strategic options for their application are explained. Business and economic benefits of standardization are described and explained using a variety of examples.

Im Rahmen der Veranstaltung wird Normung als ein strategisches Instrument in Wirtschaft und Gesellschaft vorgestellt, z.B. zum Abbau von Handelshemmnissen, für die Marktfähigkeit von Innovationen und zur Entlastung der staatlichen Regulierung.
