  2. 1. Processes and factors governing benthic community dynamics—environmental change in the Baltic Sea

    Author : Christian Sommer; Sara Sjöling; Patrik Dinnétz; Inger Porsch Hällström; Alexander Eiler; Södertörns högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Benthic communities; Baltic Sea; biodiversity; community composition; environmental change; environmental genomics; microbial ecology; Major Baltic Inflow; meta-population; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : As drivers of biogeochemical cycles and nutrient recycling, such as carbon turnover, the microbial community is essential in sustaining functioning ecosystems. Together with the metazoan community, the microbial community constitute the majority of all life in the benthos. READ MORE

  4. 2. Perfect simulation of some spatial point processes

    Author : Kajsa Larson; Olle Häggström; Chalmers University of Technology and Göteborg University Department of Mathematical Statistics; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perfect simulering; coupling from the past; Markov shain Monte Carlo; point process; Widom-Rowlinson model; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Abstract : Coupling from the past (CFTP) algorithms are presented that generate perfectly distributed samples from the multi-type Widom--Rowlinson (W--R) model and some generalizations of it. The classical W--R model is a point process in the plane or the  space consisting of points of several different types. READ MORE

  6. 4. A study of multilevel models with block circular  symmetric covariance structures

    Author : Yuli Liang; Tatjana von Rosen; Dietrich von Rosen; Abdullah Almasri; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Block circular symmetry; Covariance matrix; Explicit solution; Maximum likelihood estimator; Multilevel model; Spectrum; statistik; Statistics; Matematik;

    Abstract : This thesis concerns the study of multilevel models with specific patterned covariance structures and addresses the issues of maximum likelihoodestimation. In particular, circular symmetric hierarchical datastructures are considered. READ MORE
