A Contract-Based Language for Embedded Control Systems

A new block-oriented language called Friend is proposed. It is designed to support for the implementation of flexible and adaptive embedded control systems. Requirements on a controller are specified using contracts. The use of contracts simplifies the design and implementation of embedded systems that can adapt to altered operating conditions. The contracts allow the system to negotiate about res

The Notion of God and the Editing of the Hebrew Book of Psalms

Psalm studies at the end of the twentieth century bear witness of a major paradigm shift. Recent research no longer treats the Book of Psalms as a loosely assembled hymnbook with no overarching organization, but rather as a book that got its present shape through careful editing. In recent years an increasing interest in the arrangement of the Book of Psalms has produced a substantial volume of li

Creative organizational climate – testing Ekvall’s 10-dimension model

To measure organizational climate for creativity and innovation Ekvall’s 10-dimension model is widely used both in research and in practice. The model consists of the 10 dimensions; challenge, freedom, idea support, trust, dynamism, playfulness, debate, conflicts risk-taking, and idea time. Outgoing from these dimensions Ekvall (1996) developed the Creative Climate Questionnaire (CCQ), shown to di

A comparison of two numerical methods for homogenization of Maxwell's equations

When the wavelength is much larger than the typical scale of the microstructure in a material, it is possible to define effective or homogenized material coefficients. The classical way of determination of the homogenized coeffi- cients consists of solving an elliptic problem in a unit cell. This method and the Floquet-Bloch method, where an eigenvalue problem is solved, are numerically compared with

The Coast as Arena for Swedish Modernity

The perspective in the paper is the coast as a place for health, leisure, and recreation, and it takes its examples from southern Sweden and the city of Malmö. In Malmö the coast has been an essential and integrated part of the city’s business and image for centuries. It has been utilised and physically re-moulded for different purposes. By looking at the city coast from these perspectives, it is

High-level Synthesis of Dataflow Programs for Signal Processing Systems

The growing complexity of signal processing algorithms and platforms poses significant challenges to design methods and implementation tools. High-level dataflow programs, such as those in MPEG's RVC-CAL language, provide abstraction and the opportunity for extensive design-space exploration, but they do raise the problem of efficient automatic synthesis to hardware and software. This paper presen
