  1. 1. Land Mine Detection using Dual-Band Electro-Optical Sensing

    Författare :Magnus Lundberg; Chalmers University of Technology; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; land mines; regularization; nuisance parameters; detection; infrared imaging; occlusion modeling; multi-spectral imaging; prior knowledge; Signalbehandling; Signal Processing;

    Sammanfattning : This thesis addresses the detection of buried and partially occluded land mines using electro-optical sensing. According to the Red Cross approximately 10000 people are killed and another 30000 are injured each year in mine related accidents. LÄS MER

  2. 2. Landfill Mining : Institutional challenges for the implementation of resource extraction from waste deposits

    Författare :Nils Johansson; Joakim Krook; Mats Eklund; Myra Hird; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; SOCIAL SCIENCES; Landfill mining; recycling; mineral policy; institutions; transitions; mining.;

    Sammanfattning : The overall aim of the thesis is to examine the institutional conditions for the implementation and emergence of landfill mining. The result shows that  current policy makes it difficult for landfill mining operators to find a market outlet for the exhumed material, which means that landfill mining may result in a waste disposal problem.

  3. 3. Lake sedimentary archives of medieval mining and smelting in Sweden : tracking environmental changes from site to landscape

    Författare :Erik Myrstener; Richard Bindler; Christian Bigler; Elinor Andrén; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; environmental science; miljövetenskap;

    Sammanfattning : While the environmental impact of the industrial age is massive, including climate change, pollution, microplastics and habitat loss, our influence reaches further back than many recognize. In Sweden, an early and important activity with large potential impact was the mining and smelting of iron, copper and silver ores over the last ~800 years. LÄS MER

  4. 4. Heat and water transfer for lacquer drying and thermal signatures : modelling, simulation and experiment

    Författare :Ricardo Garcia-Padron; Roland Wimmerstedt; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The coupled phenomenon of heat and water transfer is essential in many scientific and industrial problems. This thesis focuses this phenomenon on two areas; lacquer drying and thermal signatures. Simulations of physical phenomena may in some cases replace extensive experimental investigations, which may be complicated and expensive. LÄS MER

  5. 5. Bayesian Inference with Unknown Noise Covariance

    Författare :Lennart Svensson; Chalmers University of Technology; []
    Nyckelord :;

    Sammanfattning : This thesis studies Bayesian methods in statistical signal processing. A central theme is that the treatment of the unknown noise covariance matrix is of chief concern for all scenarios. As a first application, the detection of land mines using infrared techniques is investigated. LÄS MER
