  1. 11. Colour – A Reliable Quality-Control Tool for Industrial Thermowood® Production

    Författare :Petteri Torniainen; Dennis Jones; Olov Karlsson; Dick Sandberg; Henrik Veikko Juhani Heräjärvi; Luleå tekniska universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermally-modified timber; Thermo-S; Thermo-D; colour Lab; Scots pine; Pinus sylvestris; Norway spruce; Picea abies; quality control; Träteknik; Wood Science and Engineering;

    Sammanfattning : The objective of the work presented in this doctoral thesis has been to correlate the commercial output of  ThermoWood® process with a pre-defined, quantifiable, non-destructive measurable parameter - colour, and to show the feasibility of measurements to be the essential part of the internal and external quality-control system. Colour is the most evident property changed of thermally-modified timber (TMT). LÄS MER

  3. 12. Hyperspectral Image Generation, Processing and Analysis

    Författare :Hamed Hamid Muhammed; Ewert Bengtsson; Tommy Lindell; Erkki Oja; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; hyperspectral imaging; colour filter mosaics; remote sensing; crop reflectance; surface water quality; disease severity; plant density; linear system of equations; waste water detection; chlorophyll a; suspended paticulate matter; weighted fixed neural networks; weighted incremental neural networks; camera spectrometer; Bildanalys; Image analysis; Bildanalys;

    Sammanfattning : Hyperspectral reflectance data are utilised in many applications, where measured data are processed and converted into physical, chemical and/or biological properties of the target objects and/or processes being studied. It has been proven that crop reflectance data can be used to detect, characterise and quantify disease severity and plant density. LÄS MER

  4. 13. Carrot Juice Processing - Effects on Various Quality Aspects

    Författare :Charlotte Alklint; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modified atmosphere; shelf-life; accelerated storage; isothermal calorimetry; pressing; expression method; colour; dietary fibre; carotene; composition; carrot pomace; carrot juice; carrot pulp; acidification; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : Carrots are a cold-weather crop well suited for cultivation in the south of Sweden. Carrots are generally rather inexpensive, with a market price below € 1 /kg (Sweden, 2003), whereas fresh carrot juice has a price of around € 5 /kg. LÄS MER

  5. 14. Wood colour related to kiln drying

    Författare :Bror Sundqvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Sammanfattning : Raised temperature in artificial drying has led to some changes of wood products such as colour and strength etc. For special treatment of wood-products with clearly modified properties, among them colour, is often high temperature and steam used industrially. LÄS MER

  7. 15. Heat treatment of solid wood : effects on absorption, strength and colour

    Författare :Dennis Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träfysik; Wood Physics;

    Sammanfattning : Wood is a useful construction material, but it has less desirable properties such as poor durability and poor dimensional stability. These problems can be reduced by using various chemical treatments. Increased environmental awareness has raised the demand for more environmentally friendly methods. LÄS MER
