  1. 1. Entropy, information theory and spatial input-output analysis

    Author : David F. Batten; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Commodity flows; dynamic analysis; entropy; information theory; input-output analysis; probability distributions; regional and interregional modelling;

    Abstract : Interindustry transactions recorded at a macro level are simply summations of commodity shipment decisions taken at a micro level. The resulting statistical problem is to obtain minimally biased estimates of commodity flow distributions at the disaggregated level, given various forms of aggregated information. READ MORE

  2. 2. On the ICT Economy in the European Countries: Investigating the Contribution of the ICT Sectors Using the Input – Output Model

    Author : Ibrahim Kholilul Rohman; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; input-output; ICT sectors; multiplier.; economic growth; structural change;

    Abstract : Previous studies have been devoted to investigating the future of economic growth and examining the importance of technology and the ICT sectors in accelerating the growth of the economy. These studies are from a macro perspective that emphasizes the role of infrastructure investment, as well as from the firm level analysis, which is mainly related to cost efficiency. READ MORE

  3. 3. Capacity-constrained production-inventory systems : using Laplace transforms and input-output analysis

    Author : Zhiping Wang; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Production-Inventory Systems; Computer science; Datavetenskap;

    Abstract : This work is concerned with multi-level, multi-stage capacity-constrained production-inventory problems. The aim is to provide a contribution to a theoretical background for Material Requirements Planning (MRP) using the Laplace Transform approach and Input-Output Analysis. READ MORE

  4. 4. Organizing physical flow data : from input-output tables to data warehouses

    Author : Erik Löfving; Linköpings universitet; []

    Abstract : Data on flows of materials and substances through the economy and the environment are collected by many different organizations and play a key role in the science of industrial ecology. In this thesis, a framework is suggested for structuring and organizing such data. READ MORE

  5. 5. Input-Output Stability Analysis of Networked Control Systems

    Author : Johannes Nygren; Kristiaan Pelckmans; Torkel Glad; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; L2-stability; quantization; delay; packet dropouts; switching systems; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : The main focus of the thesis is to derive stability criteria for networked control system (NCS) models featuring imperfections such as time-varying and constant delays, quantization, packet dropouts, and non-uniform sampling intervals. The main method of proof is based on matrix algebra, as opposed to methods using Lyapunov functions or integral quadratic constraints (IQC). READ MORE
