- Graph Transformation (GraTra) provides a formal, declarative means of specifying model transformation. In practice, GraTra rule applications are often programmed via an additional language with which the order of rule applications can be suitably controlled. Story-Driven Modelling (SDM) is a dialect of programmed GraTra, originally developed as part of the Fujaba CASE tool suite. Using an intuitive, UML-inspired visual syntax, SDM provides usual imperative control flow constructs such as sequences, conditionals and loops that are fairly simple, but whose interaction with individual GraTra rules is nonetheless non-trivial. In this paper, we present the first results of our ongoing work towards providing a formal step semantics for SDM, which focuses on the execution of an SDM specification.

The construction of equality : Syriac immigration and the Swedish City
- 2017

Book (peer-reviewed)abstract
- An industrial city on the outskirts of Stockholm, Södertälje is the global capital of the Syriac Orthodox Christian diaspora, an ethnic and religious minority group fleeing persecution and discrimination in the Middle East. Since the 1960s, this Syriac community has transformed the standardized welfare state spaces of the city’s neighborhoods into its own “Mesopotälje,” defined by houses with Mediterranean and other international influences, a major soccer stadium, and massive churches and social clubs. Such projects have challenged principles of Swedish utopian architecture and planning that explicitly emphasized the erasure of difference. In The Construction of Equality, Jennifer Mack shows how Syriac-instigated architectural projects and spatial practices have altered the city’s built environment “from below,” offering a fresh perspective on segregation in the European modernist suburbs. Combining architectural, urban, and ethnographic tools through archival research, site work, participant observation (among residents, designers, and planners), and interviews, Mack provides a unique take on urban development, social change, and the immigrant experience in Europe over a fifty-year period. Her book shows how the transformation of space at the urban scale-the creation and evolution of commercial and social districts, for example-operates through the slow accumulation of architectural projects. As Mack demonstrates, these developments are not merely the result of the grassroots social practices usually attributed to immigrants but instead are officially approved through dialogues between residents and design professionals: accredited architects, urban planners, and civic bureaucrats. Mack attends to the tensions between the “enclavization” practices of a historically persecuted minority group, the integration policies of the Swedish welfare state and its planners, and European nativism.

An algorithm for the relative scaling of spectra
- 1992

In: Publications of the Astronomical Society of the Pacific. - : IOP Publishing. - 0004-6280 .- 1538-3873. ; 104:678, s. 700-703703

Journal article (peer-reviewed)abstract
- A method is described for the automatic relative scaling of spectra in which one or more lines with constant flux are present. The algorithm takes into account differences in spectral resolution, flux factors, and spectral shifts. It was developed for the relative calibration of series of optical spectra obtained in variability studies of active galactic nuclei but it also can be used for other purposes, e.g., the subtraction of an underlying stellar continuum in AGN with a template spectrum. Tests show that a high degree of accuracy is obtained, and that the method is superior to scaling the spectra by eye or measuring narrow-band fluxes
