Spreadsheets are used extensively in industry: they are the number one tool for financial analysis and are also prevalent in other domains, such as logistics and planning. Their flexibility and immediate feedback make them easy to use for non-programmers. But as easy as spreadsheets are to build, so difficult can they be to analyze and adapt....

Spreadsheets are widely used in industry, because they are flexible and easy to use. Often they are used for business-critical applications. It is however difficult for spreadsheet users to correctly assess the quality of spreadsheets, especially with respect to the understandability. Understandability of spreadsheets is important, since...

Real world problems are a challenge and a motivator for students to learn understanding and using the concepts of systems and actors. But using real world problems in the classroom is not without challenges and dilemmas. In the paper we explicitly address the issue of the need for quite intense support for the students when tackling real life...

Spreadsheets are used extensively in business processes around the world and just like software, spreadsheets are changed throughout their lifetime causing maintainability issues. This paper adapts known code smells to spreadsheet formulas. To that end we present a list of metrics by which we can detect smelly formulas and a visualization...

There is a growing awareness in international policy circles that climate change may be a driver of increased migration flows. In addition to political refugees and economic migrants, climate change-induced migration and environmental migrants are increasingly recognized as categories in human migration. As climate change-induced migration is a...

Spreadsheets are often used in business, for simple tasks, as well as for mission critical tasks such as finance or forecasting. Similar to software, some spreadsheets are of better quality than others, for instance with respect to usability, maintainability or reliability. In contrast with software however, spreadsheets are rarely checked,...

To understand the actors, we need to understand their rules. Actors are organised in networks which are affected by rules. The rules also differ according what they think / value / can do.

The papers in this volume address water governance issues and phenomena from different perspectives, and at different levels. These collected papers, however, set out to address similar questions. The first is: ‘How is water governance evolving at different levels of government?’ In this question government refers to public (democratic)...

Our current familiarity with large infrastructures, the place they hold in the landscape and the roles they play in modern living combine to make us lose sight of their long-term, system-wide effects. In this paper, the action of the large infrastructures of dams in structuring both the biophysical and the societal environment in which they...

Thanks to their flexibility and intuitive programming model, spreadsheets are widely used in industry, often for businesscritical applications. Similar to software developers, professional spreadsheet users demand support for maintaining and transferring their spreadsheets. In this paper, we first study the problems and information needs of...

The use of spreadsheets to capture information is widespread in industry. Spreadsheets can thus be a wealthy source of domain information. We propose to automatically extract this information and transform it into class diagrams. The resulting class diagram can be used by software engineers to understand, refine, or re-implement the spreadsheet...

International experiences with water policy and governance arrangements are shared through various international meetings and reports. The underlying assumption is that these experiences provide useful information to policy makers who are looking for ways to improve water resources management in their home country or region. However, little has...

Domain specific languages (DSLs) are languages in which the properties of a specific domain can be expressed. In this paper we present an empirical study on the use of a DSL in industry. This DSL encapsulates the details of services that communicate using Windows Communication Foundation (WCF). From definitions of the data contracts between...

A quantitative analysis of retained austenite and nonmetallic inclusions in gas tungsten arc (GTA)–welded aluminum-containing transformation-induced-plasticity (TRIP) steels is presented. The amount of retained austenite in the heat-affected and fusion zones of welded aluminum-containing TRIP steel with different base metal austenite fractions...

Microstructural development in gas tungsten arc (GTA) welded silicon- and aluminum-based transformation-induced plasticity (TRIP) steels was studied by optical and electron microscopy. The fusion zone (FZ) of both welds contained complex inclusions. Energy-dispersive spectroscopic (EDS) analysis on these inclusions showed that the center of the...

In addition to after-laying of new-installed high voltage (HV) power cables the use of on-site non-destructive on-site testing and diagnosis of service aged power cables is becoming an important issue to determine the actual condition of the cable systems and to determine the future performances. In this paper based on field experience an...
