  2. 26. Toward Sequential Data Assimilation for NWP Models Using Kalman Filter Tools

    Author : Jelena Bojarova; Rolf Sundberg; Krzysztof Podgorski; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; non-Gaussian state space models; Kalman filtering; ETKF; 3D-Var; data assimilation; NWP; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Abstract : The aim of the meteorological data assimilation is to provide an initial field for Numerical Weather Prediction (NWP) and to sequentially update the knowledge about it using available observations. Kalman filtering is a robust technique for the sequential estimation of the unobservable model state based on the linear regression concept. READ MORE

  4. 27. Capturing change : The practice of Malian photography, 1930s-1990s

    Author : Tanya Elder; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; African photography; situated practice; bricoleur; indigenous technology; assimilation and adaptation; media technology; Mali; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : This study follows the evolution of three distinct photographic practices in Mali. It focuses on indigenous photographers in the towns of Segou, Mopti and Kayes. The first practice beginning in the 1930's, is studio photography. READ MORE

  5. 28. Rule by Association : Japan in the Global Trans-Imperial Culture, 1868-1912

    Author : John Hennessey; Hans Hägerdal; Alexis Dudden; Linnéuniversitetet; []
    Keywords : HUMANIORA; HUMANITIES; global trans-imperial culture; association; assimilation; Hokkaido; Taiwan; expositions; Japanese colonialism; Japanese Empire; colonial history; colonial administration; Historia; History;

    Abstract : Criticizing one-empire approaches, calls to apply much-needed transnational perspectives and methodologies to colonial history have recently emerged. This groundbreaking scholarship has already revealed that the competition between different European empires after 1850 has typically been overemphasized; in fact, a transnational perspective reveals extensive cooperation between the “great powers” of the age, along with myriad examples of exchanges and transfers of colonial knowledge.

  6. 29. Data assimilation of forest variables predicted from remote sensing data

    Author : Nils Lindgren; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Forest information for management planning is today gathered through a combination of field inventories and remote sensing, but the available flow of remote sensing data over time is not yet utilized for continuously improving predictions of forest variables. In the thesis, the utility of data assimilation, in particular the Extended Kalman filter, for forest variable prediction is investigated. READ MORE

  7. 30. Ammonia assimilation and nitrogen fixation in phototrophic bacteria : studies on glutamine synthease and the metabolic regulation of nitrogenase in Rhodospirillum rubrum

    Author : Abdelhamid Soliman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The phototrophic bacteria and a few other species, are able to control nitrogen fixation on the metabolic level. This is a fast and reversible mechanism, which “switches off and on” the nitrogenase activity in response to the accessibility of combined nitrogen, the energy supply and the level of oxygen in the medium.
