The Guardian reports: Twitter’s languages of New York mapped

Times Square, NY

8.5 million tweets, captured between January 2010 and February 2013, are used to illustrate languages of New York. Here is a link to the Guardian: http://www.guardian.co.uk/news/datablog/interactive/2013/feb/21/twitter-languages-new-york-mapped

James Cheshire, who generated these graphs, is a lecturer at the UCL Centre for Advanced Spatial Analysis. Read more about his research on http://spatialanalysis.co.uk

Optimierte modellprädiktive Regelung in Kaltwalzanlagen

perOptiIMG_0781

Im Rahmen des von der FH Köln geförderten Projektes PER-OPTI hielt M. Sc. Sebastian Zareba den Vortrag “Optimierte modellprädiktive Regelung in Kaltwalzanlagen” im SPOTSeven Seminar. Sebastian Zereba ist Mitarbeiter am Institut für Produktentwicklung und Konstruktionstechnik in der von Prof. Dr.-Ing. Mohieddine Jelali geleiteten Arbeitsgruppe. PER-OPTI steht für “Optimierung der Prozessführung basierend auf der automatischen Performancebewertung in modernen Walzwerken” und wurde gemeinsam von den Professoren Jelali (IPK), Haber (F09), Smajic (F08) und Bartz-Beielstein (F10) beantragt.

Es wurde deutlich, dass die vom SPOTSeven Team entwickelten Optimierungsalgorithmen einen wichtigen Beitrag für die modellprädiktive Regelung darstellen. Neben der Minimierung der Fehlerrate spielt auch die Verbesserung der Energieffizienz eine zentrale Rolle in diesem Projekt.

HANNOVER MESSE 2013: SPOTSeven shows optimization methods for reducing CO2-emmissions

Katya discussing new meta-modeling approaches

Innovative methods and software tools developed by the SPOTSeven group at Cologne University of Applied Sciences enable accurate forecasts and minimization of pollutant emissions in commercial applications in the energy sector. This and other examples from industry practice are shown by members of the SPOTSeven team at  hall 2, booth C38 at HANNOVER MESSE 2013 from April 8 to 12, 2013.

SPOTSeven develops scientific methods and software tools for industrial process analytics and optimization. These methods help to arrive at statistically secured answers to questions of rapidly increasing relevance in times of climate change and rising efficiency requirements:

  • Which parameters of an industrial process have the strongest effect on operating costs, quality, energy efficiency, and pollutant emissions?
  • What relations exist between process parameters and target quantities such as quality, costs, and efficiency?
  • Are these relations statistically significant and how can these relations be utilized for process optimization?
  • What setting of process parameters provides an optimal compromise between operating costs, quality, energy efficiency, pollutant emissions and process stability?

The research group of Prof. Dr. Thomas Bartz-Beielstein at Campus Gummersbach of Cologne University of Applied Sciences develops and integrates state-of-the-art methods from mathematics, statistics and computer science with a focus on practicality in industrial applications. At HANNOVER MESSE 2013, SPOTSeven shows examples from current projects with several industry partners.
