  1. 1. A Critical Review of the Observational Method

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

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

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Stockholm : Kungliga Tekniska högskolan

    Författare :Johan Spross; KTH.; [2016]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Stockholm : Kungliga Tekniska högskolan

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

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ida Westerberg; Uppsala universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Central America; Discharge; Flow-duration curve; Fuzzy regression; GLUE; Model evaluation; Non-stationarity; Observational uncertainty; Precipitation; Quality control; Rating curve; Regionalisation; Uncertainty estimation; Ungauged basins; Water resources; Avbördningskurva; Centralamerika; GLUE; icke-stationaritet; kvalitetskontroll; modellutvärdering; nederbörd; observationsosäkerheter; avrinningsområden utan vattenfö-ringsdata; oskarp regression; osäkerhetsuppskattning; regionalisering; varaktighetskurva; vattenföring; vattenresurser; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi; Hydrology; Hydrologi;

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Lund Observatory, Lund University

    Författare :Ralph Snel; Lunds universitet.; Lund University.; [1998]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
