  1. 6. Modelling and Inference for Spatio-Temporal Marked Point Processes

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Ottmar Cronie; Göteborgs universitet.; Gothenburg University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Asymptotic normality; Consistency; Cox-Ingersoll-Ross process; Diffusion process; Edge correction; Goodness-of-fit; Richards growth function; Growth-interaction process; Immigration-death process; Least squares estimation; Markov process; Maximum likelihood estimation; Open-growth; Spatio-temporal marked point process; Stationarity; Stochastic differential equation; Transition density;

    Sammanfattning : This thesis deals with inference problems related to the growth-interaction process (GI-process). The GI-process is a continuous time spatio-temporal point process with dynamic interacting marks (closed disks), in which the immigration-death process (ID-process) controls the arrivals of new marked points as well as their potential life-times.

  2. 7. Study of precipitation in martensitic Fe-C-Cr alloys during tempering Experiments and modelling

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ziyong Hou; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe-C-Cr alloy; Microstructure; Precipitates; Tempering of martensite; Electron microscopy; Modelling.; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Understanding the precipitation reaction is very important since precipitation hardening is one of the most effective strengthening mechanisms in metallic alloys. In martensitic steels, a tempering heat treatment is often performed. LÄS MER

  3. 8. Indoor emissions and fate of flame retardants A modelling approach

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Författare :Ioannis Liagkouridis; Stockholms universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flame retardants; BFRs; OPFRs; indoor environment; emissions; fate; modelling; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : A significant number of consumer goods and building materials act as emission sources of flame retardants (FRs) in the indoor environment. As a result, FRs have become ubiquitous indoors raising concerns about human exposure and possible health implications. LÄS MER

  4. 9. Reflections on Process-based Supply Chain Modelling and Analysis

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Författare :Robert Lindroth; Lunds universitet.; Lund University.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process mapping; supply chain management; modelling; simulation.;

    Sammanfattning : The interest in modelling, analysis and optimisation of supply chain structures has increased in the last decade. Among the reasons are globalisation, a general speed-up of the rate of change in the business environment, the trend towards more outsourcing of activities, and the rapid development in IT. LÄS MER

  5. 10. Discrete Element Modelling and Simulation of Vibratory Screens

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Ali Davoodi; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Screen efficiency; Modelling.; DEM simulation;

    Sammanfattning : In Sweden about 85 million tonnes aggregate is used for road, railway and concrete every year. Crushing is the main process for producing the aggregate material in different fractions. The crushing process is divided into two sub-processes; comminution and separation. LÄS MER
