In todays digitized and globalized economy, companies face increasing competitive pressures and unprecedented speed of change in business conditions. Considering limited IT budgets, process owners and IT departments need to decide how to divide their spending on efficiency-enhancing and flexibility-enhancing IT capabilities to optimally support their business processes. Turning from thinking of...

Component software architectures offer an alternative approach for building large, 4 complex hydrologic modeling systems. In contrast to more traditional software 5 paradigms (i.e. procedural or object-oriented approaches), using component-based 6 approaches allows individuals to construct autonomous modeling units that can be linked 7 together through shared boundary conditions during a simula...

Continuous improvement is generally considered to be a paradigm shift that occurs when organizations move from the Managed to the Optimizing Process (SEI CM Level 4 to 5). This paper supports the view that continuous improvement needs to start early to enable and guide the gradual evolution and maturation of process definition across Key Process Areas and maturity levels. It is a well known pri...

The issue of the mean signal level crossing rate for various probability density functions with primary relevance for optics is discussed based on a new analytical method. This method relies on a unique transformation that transforms the probability distribution under investigation into a normal probability distribution, for which the distribution of mean level crossings is known. In general, t...

It is a basic matter of business process modelling to determine an adequate level of model detail, a problem which also can be derived from the guidelines of modelling by Becker et al. [BRU00]. In literature, only few recommendations how to solve this problem can be found. In addition they are quite unspecific and have gaps. In this paper, we investigate which measurable factors influence the a...

MOTIVATION Cellular processes are not isolated groups of events. Nevertheless, in most microarray analyses, they tend to be treated as standalone units. To shed light on how various parts of the interlocked biological processes are coordinated at the transcription level, there is a need to study the between-unit expressional relationship directly. RESULTS We approach this issue by constructin...

This work aims at establishing the best practices and processes to define the life cycle of an SLA. For such purpose, the network management practices defined in the TMForum scope (according to the view offered by TOM [01] and eTOM [02]) are used as reference. Such best practices are distributed along the network management layer, in order to define the Network Performance indicators and their ...

Asynchronous systems are gaining acceptance as the size and complexity of digital circuits increase. Concordantly, synthesis tools for asynchronous systems must be developed to make design process easier. This paper aims at the deenition of basic concepts for scheduling algorithms and control synthesis in high-level synthesis of asynchronous circuits. Two scheduling strategies are presented and...

In current literature few detailed process models for Requirements Engineering are presented: usually high-level activities are distinguished, without a more precise specification of each activity. In this paper the process of Requirements Engineering has been analyzed using knowledgelevel modelling techniques, resulting in a well-specified compositional process model for the Requirements Engin...

A multicomputer system consisting of hundreds of processors interconnected by point-to-point links can achieve high performance for many important applications. We propose a new application-transparent, process-level, distributed error recovery scheme for multicomputers. Checkpointing is initiated by timers at intervals determined by the needs of the application. Checkpointing and recovery invo...
