  1. 6. Modelling Evolution : From non-life, to life, to a variety of life

    Author : Yu Liu; David J. T. Sumpter; Peter Dittrich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematical biology; Biocomplexity; Artificial chemistry; Ecosystem evolution; Origin of life; Self-replication; Prebiotic evolution; Collectively-catalytic; Golden ratio; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Abstract : Life is able to replicate itself, e.g., a microorganism is able to divide into two identical ones, and a single plant is able to forest a whole island. READ MORE

  2. 7. Environmental Modelling : Learning from Uncertainty

    Author : John M. Juston; Per-Erik Jansson; Jens Christian Refsgaard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Models; data; error; uncertainty; hydrology; soil carbon; wetlands; phosphorus;

    Abstract : Environmental models are important tools; however uncertainty is pervasive in the modeling process.   Current research has shown that under­standing and representing these uncertainties is critical when decisions are expected to be made from the modeling results. READ MORE

  3. 8. Of Mice and MYC : Modelling Medulloblastoma

    Author : Oliver Mainwaring; Fredrik J. Swartling; Charles Eberhart; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medulloblastoma; MYC; Group 3; Cdkn2a; ARF; HSP90; Chromosome 17q; Medicinsk vetenskap; Medical Science; Oncology; Onkologi;

    Abstract : Brain tumours are the leading cause of cancer-related paediatric deaths, with medulloblastoma (MB) being the most common malignant paediatric brain tumour. MB is stratified into four major subgroups – WNT, SHH, Group 3, and Group 4, nomenclature defined by key pathways and drivers involved within each subgroup. READ MORE

  4. 9. System Expansion and Allocation in Life Cycle Assessment With Implications for Wastepaper Management

    Author : Tomas Ekvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; paper recycling; waste incineration; environmental life cycle assessment; LCI methodology; allocation; waste management; system expansion; system boundaries; life cycle inventory analysis;

    Abstract : The choice of system boundaries and allocation methods can have decisive effects on the results and conclusions of a life cycle assessment (LCA). System expansion makes it possible to model the indirect effects of a decision; however, this modelling is often based on inaccurate assumptions. READ MORE

  5. 10. Bringing System Dynamics into Action Research

    Author : Paul Holmström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; process consultation; Operations Research; simulation; action research; modelling; System Dynamics; healthcare;

    Abstract : System Dynamics simulation is a computer-aided approach to policy analysis and design, often carried out by external experts in simulation. System Dynamics is particularly useful in complicated and complex situations, such as healthcare. However, research has shown that few models in healthcare are implemented. READ MORE
