Web service technologies are becoming increasingly important for integrating systems and services. There is much activity and interest around standardization and usage of web service technologies. Contemporary web services are described in the Web Service Description Language (WSDL). However, WSDL...

It is common knowledge that incidents and accidents often are caused by failures of operational barriers. The Risk level project has demonstrated this clearly for hydrocarbon leaks. A concept study of) Operational Safety condition (OTS) has been prepared in 2006. The purpose of the OTS system is to...

In large scale emergencies with many casualties, personnel require an updated view of the situation at all times to contribute effectively to the rescue operation.   Experience from full scale field exercises shows that the tools available today - mainly paper forms and radio communication - do not...

Different methods of sensitivity analysis for thermal design and monitoring problems are described and applied on furnace liningproblems. The methods used in this work are based on utilizing finite differences and sensitivity equations; the former being code non-invasive while the latter class of...

Analysis of stream-line-based formulations is exercised to develop a stream-line based semi-analytical model for the single-well push-pull test, taking into account natural ground-water drift. The model is employed to calculate the time of breakthrough for clean water and the end-time of tracer...

To design usable mobile applications, exploiting context changes is of vital importance. The rapid context changes in a mobile setting cause the need for flexible and adaptive user interfaces that are multitasking and possibly exploiting multiple modalities. Implementing adaptive user interfaces...

We present a method for (1) specifying high-level security policies using UML sequence diagrams and (2) transforming high-level sequence diagram policies into low-level state machine policies that can be enforced by monitoring mechanisms. We believe that the method is both easy to use and useful...

This paper describes an approach to representing contextual informationthrough a domain independent solution. It, further more, shows how casebasedreasoning can be used to reason about user-situations.The solutions described is implemented within a context-aware system supportingusers in an mobile...

Many geophysical flows are merely perturbations of some fundamental equilibrium state. If anumerical scheme shall capture such flows efficiently, it should be able to preserve the unperturbed equilibrium state at the discrete level. Here, we present a class of schemes of any desired order of...

In Model-Driven Engineering (MDE), models are the prime artifacts, and developing high-quality systems depends on developing high-quality models and performing transformations that preserve quality or even improve it. This paper presents quality goals in MDE and states that the quality of models is...

Increased efficiency of building information flow depends on clearly defined data in the information package to be exchanged. IFC goes a long way to provide this, but falls short in many important scenarios that deals with product information. IFD, or the buildingSMART ontology, brings us one step...
