  1. 1. A Critical Review of the Observational Method

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Johan Spross; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock mechanics; observational method; Eurocode 7; reliability analysis; dam safety; tunnelling; system reliability; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Building a sustainable structure in soil or rock that satisfies all predefined technical requirements implies choosing a rational and effective construction method. An important aspect is how the performance of the structure is verified. READ MORE

  2. 2. Toward a reliability framework for the observational method

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Johan Spross; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock engineering; observational method; Eurocode 7; structural safety; reliability analysis; dam safety; Bergmekanik; observationsmetoden; Eurokod 7; sannolikhetsbaserad dimensionering; dammsäkerhet; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Constructing sustainable structures in rock that satisfy all predefined technical specifications requires rational and effective construction methods. When the geotechnical behaviour is hard to predict, the Euro­pean design code, Eurocode 7, suggests application of the observational method to verify that the performance is acceptable. READ MORE

  3. 3. Geological Characterisation and the Observational Method. Application of Value of Information Analysis

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Miriam Zetterlund; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Value of Information Analysis; Rock mass characterisation; Observational Method;

    Abstract : The implementation of the new European standards for geotechnical design calls for new practice in the underground construction industry in Sweden. The standard proposes the Observational Method as an alternative method when the geotechnical behaviour is difficult to predict. READ MORE

  4. 4. Observational Uncertainties in Water-Resources Modelling in Central America Methods for Uncertainty Estimation and Model Evaluation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ida Westerberg; Uppsala universitet.; [2011]

    Abstract : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. READ MORE

  5. 5. Crowded Field Photometry and Luminosity Function Analysis as Probes of Galactic Evolution

    University dissertation from Lund Observatory, Lund University

    Author : Ralph Snel; Lunds universitet.; Lund University.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; observational; Methods: data analysis; statistical - Techniques: photometric - Stars: luminosity function; imaging; evolution - Galaxies: stellar content; mass function; space research; cosmic chemistry; Astronomi; rymdvetenskap; kosmisk kemi; Fysicumarkivet A:1998:Snel;

    Abstract : Crowded field photometry is a powerful method to investigate stellar evolutionary processes in astrophysically interesting regions such as nearby external galaxies and globular cluster cores. While detectors are approaching the physical limits for photon detection, data analysis methods for crowded stellar fields are not yet equally sophisticated. READ MORE
