  1. 16. Predictions Within and Across Aquatic Systems using Statistical Methods and Models

    Författare :Peter H. Dimberg; Roger Herbert; Andreas C. Bryhn; Gesa Weyhenmeyer; Mikael Malmaeus; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lake; Water quality; Chlorophyll-a; Total phosphorus; Seasonality; Morphometry; Regression model; Probability; Markov chain; Genetic programming; Temporal-trend; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Sammanfattning : Aquatic ecosystems are an essential source for life and, in many regions, are exploited to a degree which deteriorates their ecological status. Today, more than 50 % of the European lakes suffer from an ecological status which is unsatisfactory. LÄS MER

  2. 17. Systematic Analysis of Engineering Change Request Data - Applying Data Mining Tools to Gain New Fact-Based Insights

    Författare :Ívar Örn Arnarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Markov chain; Machine learning.; Product Development; Design Structure Matrix; Design Analytics; Engineering Change Request;

    Sammanfattning : Large, complex system development projects take several years to execute. Such projects involve hundreds of engineers who develop thousands of parts and millions of lines of code. During the course of a project, many design decisions often need to be changed due to the emergence of new information. LÄS MER

  3. 18. Applying Design Analytics to Understand Engineering Change Request Information

    Författare :Ívar Örn Arnarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Design Structure Matrix; Design Analytics; Engineering Change Request; Markov chain.; Product Development;

    Sammanfattning : Large complex system development projects take several years to carry out. Such projects involve hundreds of engineers who develop tens of thousands of parts and millions of lines of code. During the course of a project, many design decisions often need to be changed due to the emergence of new information. LÄS MER

  4. 19. Case studies in omniparametric simulation

    Författare :Fredrik Lundin; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; growth model; Ising model; Markov chain; omnithermal simulation; omniparametric simulationpercolatiion; Potts model; parameter estimation; partial observations; random cluster model; Richardson model; simulation driven parameter estimation; two-type Richardson model; omnithermal simulation;

    Sammanfattning : In the eld of particle systems and growths models simulation is an important tool. When explicit calculations are too complex or impossible to perform we may use simulations instead. We adapt a new technique here denoted omniparametric simulation, to the two-type Richardson, Ising and Potts models. LÄS MER

  5. 20. On Perfect Simulation of Markovian Queueing Networks with Blocking

    Författare :Dan Mattsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Markov chain; Monte Carlo methods; Propp-Wilson algorithm; perfect simulation; queueing theory; Jackson networks; birth and death processes; Jackson networks;

    Sammanfattning : Perfect simulation of a class of Markovian queueing networks with finite buffers is examined in this monograph. The network processes defined are modelled by restricted multivariate birth and death processes with intensities depending on a random environment. The random environments are mainly a set of independent onoff processes. LÄS MER
