Wide Area Measurement Systems (WAMS) enable real time monitoring and control of smart grids by combining digital measurement devices, communication and control systems. As WAMS consist of various infrastructures, they imply complex dependencies among their underlying systems and components of different types, such as cyber, physical and geographical dependencies. Although several works exist in...

This paper presents a methodology for requirement prioritization. The approach provides a flexible and realistic approach that considers all attributes of particular requirements and fuses them into a unified metric, representative of all quality criteria identified for a specific software project. The derived quality measurement can be used as the main metric for requirements prioritization. T...

Integrated environments in general may support the four integration areas: data-integration, control-integration, presentation-integration and process-integration. The SISIP architecture takes a unified object-oriented approach to these four integration areas. The underlying infrastructure is based on distributed persistent objects, realized by a combination of objectoriented database technolog...

The paper presents a concept of support for the design and analysis of Internet security systems with a rule-based methodology. It considers a web security architecture, including a network and applicationlevel firewall with intrusion detection systems. The XTT methodology allows for hierarchical design, and on-line analysis of rule-based systems. It is applied using the Unified Firewall Model,...

This paper reports an academic experience at the Instituto Tecnológico de Aeronáutica ITA in real time embedded system development. The adopted methodology involves tailoring of the IBM Rational Unified Process (RUP) supported by Software Engineering recommended practices. A case study related to a hydrometeorological context is used to demonstrate the application of this methodology together w...

Health analytics (HA) is used in healthcare systems for effective decision making, management and planning of healthcare and related activities. However, user resistances, unique position of medical data content and structure (including heterogeneous and unstructured data) and impromptu HA projects have held up the progress in HA applications. Notably, the accuracy of outcomes depends on the sk...

Ontologies are the backbone of the Semantic Web, a semantic-aware version of the World Wide Web. The availability of large-scale high quality domain ontologies depends on effective and usable methodologies aimed at supporting the crucial process of ontology building. Ontology building exhibits a structural and logical complexity that is building methodology that capitalizes the large experience...

Collaborative business making is emerging as a possible solution for the difficulties that Small and Medium Enterprises (SMEs) are having in the current difficult economic scenarios. Collaboration, as opposed to competition, provides a competitive advantage to companies and organizations that operate in a joint business structure. When dealing with multiple organizations, managers must access u...

This paper deals with embedded systems modelling, mixed hardware/software codesign, and more generally structured codesign methodology for avionics systems. This methodology is based on two main concepts: multi-formalism specifications and a unified system model. The multi-formalism concept allows to combine partial specifications expressed in various formalisms. As a matter of fact, an embedde...

Today’s digital systems usually consist of interacting hardware and software components of high complexity. Design of such systems requires support of efficient design methodologies and automatic/semiautomatic tools. This paper presents an integrated design methodology and some design tools which have been developed at Linköping University. We introduce the methodology which is based on a unifi...
