Business rules play a critical role during decision making when executing business processes. Existing modelling techniques for business rules offer modellers guidelines on how to create models that are consistent, complete and syntactically correct. However, modelling guidelines that address manageability in terms of anomalies such as insertion, update and deletion are not widely available. Th...

Long-term reliability and manageability of high-end storage systems for scientific computing will become an increasingly important issue as disk-based storage systems grow to handle petabytes and, eventually, exabytes of data. Storage systems cannot simply be upgraded by replacing them; instead, they must grow over time. Managing and replacing the thousands of individual devices that make up su...

The goal of this paper is to show the beneets of using reeec-tive techniques and meta-programming in the context of active networks, i.e. networks where packets may contain code which programs the net-work's behavior. By having separate base-levels and meta-levels it is possible to increase the manageability of systems constructed with mobile code, since we may intercept and innuence from the m...

Abstract This paper sets new criteria to improve windows design strategies using participatory ergonomics and the grounded theory method. Focus groups are used investigate participants' reactions discussions about visual stimuli their deduction in terms of further employment specific window techniques or uses. Results framework is established through relevance relationship between 25 coded cate...

This paper investigates the mediating role of perceived usefulness and ease use on effect online learning self-efficacy factors: in an environment, time management, technology to students' behavioral intention management system. A cross-sectional explanatory research design was employed collect interpret data gathered from 470 senior high students. Mediation analyses were initiated using PROCES...

Studying the performance of a distributed system without taking care on the impact of its management system will falsify the understanding of its overall performance, especially its productivity. We propose a metric called MIM (Management Impact Metric) to evaluate this impact by varying one or several impact factors related to the management system within a management strategy of the managed s...

The design processes of todays more and more complex automation systems require computer-based support to maintain their manageability. As a base for that, the authors introduce a holistic design approach for these systems. Requirements on the system to be designed are represented by an extended feature model which serves as consistent requirements model during the entire design process. A gram...

Systems built from commodity processors dominate high-performance computing today, with systems containing thousands of processors now being deployed. Moreover, we face new challenges from processor power budget limits, shrinking transistor feature sizes, and intra-chip parallelism. As node counts for multi-teraflop systems grow to tens of thousands, with proposed petaflop system likely to cont...

Context-based systems slowly emerge from research settings to usage practice. Consequently, next to questions dealing with the technological feasibility, questions dealing with the manageability and transparency of context-based services from a user perspective come to the fore. In particular, ubiquitous computing applications help bridging between virtual and real-world context dimensions (wit...

Due to the growing importance of alignment, compliance and manageability issues, increased attention is being paid to architectures and architecture management recently. A holistic approach to enterprise architecture requires business related and information systems related artifacts to be equally treated. This paper describes the extension of an existing approach to enterprise architecture and...
