Detailed dynamic simulations of three industrial distillation columns (a propylene/propane splitter, a xylene/toluene column, and a depropanizer) have been used to study the issue of configuration selection for diagonal PI dual composition controls. ATV identification (Astrom and Hagglund, 1988) with on-line detuning was used for tuning the diagonal PI composition controllers. Each configuratio...

Regionalization, or the grouping of objects in space, is a useful tool for organizing, visualizing, and synthesizing the information contained in multivariate spatial data. Landscape pattern indices can be used to quantify the spatial pattern (composition and configuration) of land cover features. Observable patterns can be linked to underlying processes affecting the generation of landscape pa...

This study aimed to assess ecological quality status of hard substratum macroinvertebrates communities of the Caspian Sea with three ecological indices and their relation with environmental factors. For this purpose benthic communities of the Caspian Sea basin were studied seasonally during 2014 in 8 sampling sites. Temperature, salinity, dissolved oxygen, pH, nitrate, nitrite, silicate and pho...

This paper examines the use of constraint-based configuration for the composition of Web Services. Web Services are widely assumed to represent the basis for the next generation of flexible distributed applications in B2B E-commerce, and the composition of complex applications from individuals services has attracted much attention. We show how this composition problem can be addressed at increa...

This study examined the number of writing samples needed to obtain a reliable estimate of young struggling writers’ capabilities. It further assessed if performance in one genre was reflective of performance in other genres for these children. Secondand third-grade students (81 boys, 56 girls), who were identified as struggling writers in need of special assistance by their teacher and scored a...
