  2. 1. A Systems Tool for Prescriptive Policy Analysis : Labelled Causal Mapping Method for Policy-oriented Modelling, Simulation and Decision analysis

    Author : Osama Ibrahim; Aron Larsson; David Sundgren; Maja Schlüter; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Public Policy; Systems analysis; Causal mapping; Policy modelling and simulation; Policy evaluation; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : The elicitation and processing of relevant information is the core of any policy decision-making process. Modelling is about making sense of the available information. Models are able to incorporate the contextual influences on policy making (e.g. READ MORE

  4. 2. On Kinematic Modelling and Iterative Learning Control of Industrial Robots

    Author : Johanna Wallén; Mikael Norrlöf; Svante Gunnarsson; Geir Hovland; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial robots; kinematics; Maple; modelling; iterative learning control; experiments; Automatic control; Reglerteknik;

    Abstract : Good models of industrial robots are necessary in a variety of applications, such as mechanical design, performance simulation, control, diagnosis, supervision and offline programming. This motivates the need for good modelling tools. In the first part of this thesis the forward kinematic modelling of serial industrial robots is studied. READ MORE

  5. 3. Developing Methods for Modelling Procedures in System Analysis and System Dynamics

    Author : Hördur Haraldsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Dynamics; System Analysis; group model building; modelling procedures; innovation phases; modelling workflow; Natural science; Naturvetenskap; Technological sciences; Teknik;

    Abstract : System Thinking is the mindset of defining and confining a problem and its symptoms as well as a method for communicating system understanding. System Analysis is taking that problem apart to understand its causalities and structural arrangement. READ MORE

  6. 4. Probabilistic Sequence Models with Speech and Language Applications

    Author : Gustav Eje Henter; W. Bastiaan Kleijn; Arne Leijon; Gernot Kubin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time series; acoustic modelling; speech synthesis; stochastic processes; causal-state splitting reconstruction; robust causal states; pattern discovery; Markov models; HMMs; nonparametric models; Gaussian processes; Gaussian process dynamical models; nonlinear Kalman filters; information theory; minimum entropy rate simplification; kernel density estimation; time-series bootstrap;

    Abstract : Series data, sequences of measured values, are ubiquitous. Whenever observations are made along a path in space or time, a data sequence results. To comprehend nature and shape it to our will, or to make informed decisions based on what we know, we need methods to make sense of such data. READ MORE

  7. 5. 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
