  1. 1. Designing Information Technology for Emergency Response

    University dissertation from Göteborg : University of Gothenburg

    Author : Jonas Landgren; Göteborgs universitet.; Gothenburg University.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emergency response; Sensemaking; Mobile technology; Ethnography; Design;

    Abstract : This thesis contributes to our understanding of information technologyuse in emergency response work and how information technology couldbe designed to provide support in emergency response work. The work domainof operative emergency response has been studied by extensive ethnographicfieldwork at several different fire and rescue services in Sweden. READ MORE

  2. 2. Evaluating the performance of TEWA systems

    University dissertation from Örebro : Örebro universitet

    Author : Fredrik Johansson; Högskolan i Skövde.; Högskolan i Skövde.; Örebro universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technology; air defense; information fusion; performance evaluation; threat evaluation; TEWA; weapon allocation; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY Information technology; TEKNIKVETENSKAP Informationsteknik; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Abstract : It is in military engagements the task of the air defense to protect valuable assets such as air bases from being destroyed by hostile aircrafts and missiles. In order to fulfill this mission, the defenders are equipped with sensors and firing units. To infer whether a target is hostile and threatening or not is far from a trivial task. READ MORE

  3. 3. Visual analytics for maritime anomaly detection

    University dissertation from Örebro : Örebro universitet

    Author : Maria Riveiro; Högskolan i Skövde.; Högskolan i Skövde.; Örebro universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technology; visual analytics; anomaly detection; maritime traffic monitoring; analytical reasoning; information fusion; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY Information technology; TEKNIKVETENSKAP Informationsteknik; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Abstract : The surveillance of large sea areas typically involves  the analysis of huge quantities of heterogeneous data.  In order to support the operator while monitoring maritime traffic, the identification of anomalous behavior or situations that might need further investigation may reduce operators' cognitive load.

  4. 4. Predictive Techniques and Methods for Decision Support in Situations with Poor Data Quality

    University dissertation from Örebro University

    Author : Rikard König; Högskolan i Skövde.; Högskolan i Skövde.; Högskolan i Borås.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology; TEKNIKVETENSKAP Informationsteknik; Teknik; Technology; Rule Extraction; Genetic Programming; Uncertainty estimation; Machine Learning; Artificial Neural Networks; Data Mining; Information Fusion; rule extraction; genetic programming; uncertainty estimation; machine learning; artificial neural networks; information fusion; Computer Science; data mining;

    Abstract : Today, decision support systems based on predictive modeling are becoming more common, since organizations often collect more data than decision makers can handle manually. Predictive models are used to find potentially valuable patterns in the data, or to predict the outcome of some event. READ MORE

  5. 5. Utilizing Diversity and Performance Measures for Ensemble Creation

    University dissertation from Örebro universitet

    Author : Tuve Löfström; Högskolan i Skövde.; Högskolan i Skövde.; Högskolan i Borås.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; Teknik; Technology; Ensemble Learning; Machine Learning; Diversity; Artificial Neural Networks; Data Mining; Information Fusion; ensemble learning; machine learning; diversity; artificial neural networks; information fusion; Computer Science; data mining;

    Abstract : An ensemble is a composite model, aggregating multiple base models into one predictive model. An ensemble prediction, consequently, is a function of all included base models. Both theory and a wealth of empirical studies have established that ensembles are generally more accurate than single predictive models. READ MORE
