  1. 1. Multivariate Networks Visualization and Interaction Techniques

    Författare :Ilir Jusufi; Linnéuniversitetet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information Visualization; Multivariate Networks; Visual Analytics; Exploration; Interaction; Computer Science; Datavetenskap; Information and software visualization; Informations- och programvisualisering;

    Sammanfattning : As more and more data is created each day, researchers from different science domains are trying to make sense of it. A lot of this data, for example our connections to friends on different social networking websites, can be modeled as graphs, where the nodes are actors and the edges are relationships between them.

  2. 2. Nonionic surfactants A multivariate study

    Detta är en avhandling från Umrå : Umeå University, Department of Chemistry, Organic Chemistry

    Författare :Lise-Lott Uppgård; Umeå universitet.; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AEO; APG; aquatic toxicity; cellulose reactivity; Fock; MLR; multivariate data analysis; nonionic surfactant; PCA; physicochemical properties; PLS; QSAR; surface activity; viscose; MEDICINE Chemistry; MEDICIN Kemi;

    Sammanfattning : In this thesis technical nonionic surfactants are studied using multivariate techniques. The surfactants studied were alkyl ethoxylates (AEOs) and alkyl polyglucosides (APGs). The aquatic toxicity of the surfactants towards two organisms, a shrimp and a rotifer, was examined. The specified effect was lethality, LC50, as indicated by immobilisation. LÄS MER

  3. 3. Univariate and Multivariate Surveillance of Outbreaks

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Linus Schiöler; Göteborgs universitet.; Gothenburg University.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; change-points; expected delay; exponential family; false alarms; generalised likelihood; inference principles; influenza; MEWMA; monitoring; multivariate; ordered regression; performance metrics; outbreak; predictive value; subjective judgment; spatial; statistical models; surveillance; tularemia;

    Sammanfattning : In many areas there is a need to monitor observations in order to detect changes in the underlying processes as quickly as possible. The theory of statistical surveillance provides the possibility of making optimal decisions about whether a change has occurred or not based on the data available at the time of the decision.

  4. 4. Continuous monitoring of mineral processes with special focus on tumbling mills a multivariate approach

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Kent Tano; Luleå tekniska universitet.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Increasing emphasis on productivity and quality control has provided an impetus to research on better methodologies for diagnosis, modelling, monitoring, control and optimisation of mineral process systems. One of the biggest challenges facing the research community is the processing of raw sensor data into meaningful information. LÄS MER

  5. 5. Modelling and prediction of drug transport processes with experimental and calculated molecular properties A multivariate approach

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Thomas Österberg; Uppsala universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : Less than 2% of the lead compounds generated by the pharmaceutical industry enter the exploratory drug-development phase, from which point they stand only a 10% chance of becoming a commercial medicine. A large proportion of the compounds fail due to poor biopharmaceutical properties, such as permeability and solubility. LÄS MER
