  2. 1. Automation, hyphenation and multidimensional chromatography for PAH analysis : Analytical techniques to simplify sample complexity

    Author : Hwanmi Lim; Roger Westerholm; Christoffer Bergvall; Stephen Wise; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polycyclic aromatic hydrocarbon; PAH; benzo[a]pyrene; B[a]P; carcinogenicity; cancer risk assessment; complex matrix; automation; hyphenation; multidimensional chromatography; two-dimensional; method translation; online fractionation; benz[j]aceanthrylene; B[j]A; relative potency factor; Analytical Chemistry; analytisk kemi;

    Abstract : One group of organic environmental pollutants which are potentially hazardous to human health is polycyclic aromatic hydrocarbons (PAHs). These compounds consist of two or more benzene rings in their structure among which benzo[a]pyrene (B[a]P) is classified as a human carcinogen. READ MORE

  4. 2. Segmentation of Laser Range Radar Images using Hidden Markov Field Models

    Author : Predrag Pucar; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Segmentation; Images; Model based stochastic techniques; Image processing; Demanding algorithms; Hidden Markov model; Estimation; Automatic control; Reglerteknik;

    Abstract : Segmentation of images in the context of model based stochastic techniques is connected with high, very often unpracticle computational complexity. The objective with this thesis is to take the models used in model based image processing, simplify and use them in suboptimal, but not computationally demanding algorithms. READ MORE

  5. 3. Dynamics of Discrete Curves with Applications to Protein Structure

    Author : Shuangwei Hu; Antti J. Niemi; Maxim Zabzine; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Frenet equations; integrable model; folded proteins; discrete curves; Fysik; Physics; Physical Biology; Fysikalisk biologi;

    Abstract : In order to perform a specific function, a protein needs to fold into the proper structure. Prediction the protein structure from its amino acid sequence has still been unsolved problem. The main focus of this thesis is to develop new approach on the protein structure modeling by means of differential geometry and integrable theory. READ MORE

  6. 4. Scientific methods for integrating expert knowledge in Bayesian models

    Author : Dmytro Perepolkin; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bayesian inference; Expert judgement; Quantile-parameterized distributions; Quantile functions;

    Abstract : Generating scientific advice to environmental management involves assessments with complex models, sparse data, and challenging empirical experiments, necessitating the integration of expert judgment with data into scientific models. To integrate expert judgement, assessors might elicit judgement by experts as quantiles, find a probability distribution that matches the quantiles, and add this information to the model. READ MORE

  7. 5. Tools for Understanding, Debugging, and Simulation Performance Improvement of Equation-based Models

    Author : Martin Sjölund; Peter Fritzson; Dirk Zimmer; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Simulation; modelling; debugging; profiling; optimisation; parallelism; Modelica;

    Abstract : Equation-based object-oriented (EOO) modelling languages provide a convenient, declarative method for describing models of cyber-physical systems.Because of the ease of use of EOO languages, large and complex models can be built with limited effort. READ MORE
