the emerging standard for the platform- and system-independent representation of data mining models PMML (predictive Model Markup Language) is currently supported by a number of knowledge discovery support engines. the primary purpose of the PMML standard is to separate model generation from model storage in order to enable users to view, post-process, and utilize data mining models independently of the tool that generated the model. In this paper two systems, called VizWiz and PEAR, are described. these software packages allow for the visualization and evaluation of data mining modelsthat are specified in PMML. they can be viewed. as decision support systems, since they enable non-expert users of data mining results to interactively inspect and evaluate these results.
Automated finite-state verification techniques have matured considerably in the past several years, but state-space explosion remains an obstacle to their use. theoretical lower bounds on complexity imply that all of ...

this paper presents a techno-economic evaluation of combined UMTS and WLAN operator business case spanning years 2002-2011. the study is based on the work by the TONIC project [I] under the European Union IST (Information Society Technologies) programme [2]. the study provides a framework to compare all the main factors affecting the UMTS operator's business case and evaluation of the WLAN profitability impact as complementary access technology. the example cases differ in country demographics and rollout plans relating to competition and demand situation and regulatory requirements.

Requirements engineering for technical systems involves an intricate interplay of conceptual synthesis of alternative requirements and design configurations, preliminary impact analysis of these alternatives using complex simulations and multimedia visualizations, and human decision-making based on goal trade-offs. Requirements traceability in such settings must be both product- and process-oriented: it must enable an efficient media-based comparison of product alternatives from the current project or related experiences, and it must facilitate reuse of analysis process experiences to avoid unnecessary repetition of negative experiences. We study these problems in a large interdisciplinary project whose aim it is to optimize the innovation supply chains linking chemical engineering, plastics engineering, and application goals e.g. in the automotive industry.
Assurance that a formal specification (system specification or software specification) possesses desired properties can be achieved through (1) manual inspections, (2) formal verification of the desired properties, or...

there is a growing need to reduce the cycle of business information systems development and make it independent of underlying technologies. Model driven synthesis of software offers solutions to these problems. this article describes a set of tools and methods applicable for synthesizing business software from technology independent models. this method and these tools are distinguished by the use of extended meta-models which embody knowledge of the problem domain and target software architecture of the synthesized software system by the use of the model conversion rules described using the combined metamodel and by the use of reference models of problem domains and sub-domains, which are combined and extended during the construction of software system descriptions. the difference of our method from other domain specific methods is the separate step of solution domain analysis and the use of meta-model extensions. this study has been done in the context of developing product-line architecture for insurance applications.
