The parallel structure of dataflow programs and their support for processing streams of data make dataflow programming an interesting tool for doing stream processing on parallel processing architectures. The computational kernels, the actors, of a dataflow program communicate with other actors via FIFO channels. The actors in the dataflow model used in this paper may perform different actions dep

It is well known that nature offers an abundance of materials and processes that can be adapted in low-tech fashion, to fabricate systems capable of removing pollutants from wastewater. During the last decade, extensive basic and engineering research on such natural treatment systems have led to improvement of the quality of discharged wastewaters. However, the mechanisms of natural treatment and

Artikeln, som bygger på en föreläsning vid teologdagarna 2001, behandlar den svenska utvecklingen från 1686 (den gemensamma religionen definieras och kontrolleras) över 1781, 1783 och 1809 (undantagen definieras och kontrolleras), 1827 (Wieselgrens Vilken är Sveriges religion?), 1860 och 1873 (registrerad religion blir accepterad religion), 1951 (frihet till och från religion garanteras), 1999 (de

Using classical design methods for tillage machines does not completely guarantee a safety and satisfactory performance, due in part to the randomness of tillage forces. This randomness is derived from the variability in soil engineering properties and the variations in tool design parameters and operational conditions. In this paper, a reliability-based design approach was developed, for the firs

The aerosols from 13 common electric arc welding processes have been characterized regarding total emission, particle size distribution, elemental composition and, when applicable, the oxidation state of chromium. The characterizations have been performed systematically for different combinations of welding current and welding voltage.

A fast 2D motion estimator has been developed and evaluated. The method does not utilize block-matching or iterative solutions and is thus more computationally efficient and suitable for real-time motion estimation over the entire image. The method has been evaluated on 1) phantom measurements and 2) in vivo on the carotid artery wall of 17 subjects, where measurements of the longitudinal displace

A theoretical approach to communication management/PR based on participatory observation of 8 heads of communication in German companies

A biography on the swedish king Oscar I, 1799-1859.

The influence of hydrophobic modification on solution properties of water-soluble polymers in the semi-dilute regime have been studied. The nonionic ethyl(hydroxyethyl)cellulose (EHEC) and its hydrophobically modified analogue (HM-EHEC) are used as model substances. Interactions between the polymer molecules in solution and a third component are investigated, and in particular the influence of the

The aim of this paper is to analyze, with a broadly postcolonial sensibility, the discourses on culture found in some of the international management books that: 1) especially claim to emphasize the cultural factor, and 2) claim to be ‘international’, supposedly appropriate for reading in all parts of the globe. We intend to show that very similar discursive patterns characterize the conceptualiza
