  1. 1. Biomass gasification in ABFB Tar mitigation

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

    Författare :Nemanova Vera; Klas Engvall; Joan Salvadó; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ash; biomass; char; gasification; iron-based; petcoke; tar; Chemical Engineering; Kemiteknik;

    Sammanfattning : Biomass gasification may be an attractive alternative for meeting future energy demand. Although gasification is a mature technology, it has yet to be fully commercialised due to tar formation. This study focuses on the tar mitigation in gas produced in an atmospheric bubbling fluidised bed (ABFB) gasification system. LÄS MER

  2. 2. Climate change mitigation in China

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

    Författare :Bo Xu; Ronald Wennersten; Kerstin Kuchta; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; China; Climate change mitigation; Environmental Kuznets Curve EKC hypothesis; Mitigation target; Business-as-usual BAU scenarios; Policy instruments;

    Sammanfattning : China has been experiencing great economic development and fast urbanisation since its reforms and opening-up policy in 1978. However, these changes are reliant on consumption of primary energy, especially coal, characterised by high pollution and low efficiency. LÄS MER

  3. 3. Plastic Shrinkage Cracking In Concrete Mitigation and Modelling

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Faez Sayahi; Mats Emborg; Andrzej Cwirzen; Hans Hedlund; Pietro Lura; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Early-age (up to 24 hours after casting) cracking may become problematic in any concrete structure. It can have a negative influence on the aesthetics of the concrete structure, as well as decreasing the durability and serviceability by facilitating the ingress of harmful materials into the concrete bulk.

  4. 4. Nonlinearity mitigation in phase-sensitively amplified optical transmission links

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Kovendhan Vijayan; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; copier-PSA; nonlinearity mitigation; phase-sensitive amplifier; self-phase modulation mitigation; low-noise amplification; optical transmission; crossphase modulation mitigation;

    Sammanfattning : The fundamental limitations in fiber-optic communication are caused by optical amplifier noise and the nonlinear response of the optical fibers. The quantum-limited noise figure of erbium-doped fiber amplifier (EDFA) or any phase-insensitive amplifier is 3 dB. LÄS MER

  5. 5. Land-use competition and agricultural greenhouse gas emissions in a climate change mitigation perspective

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :David Bryngelsson; [2015]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bioenergy; Diets; Livestock; Integrated assessment model; Land use competition; GHG emissions; Partial equilibrium model; Mitigation; Food consumption; Climate change;

    Sammanfattning : Productive land for food production, bioenergy, or preservation of nature is a limited resource. Climate change mitigation puts additional pressure on land via higher demand for bioenergy to replace fossil fuels and via restrictions on deforestation—two processes that limit the availability of land for food produc- tion, and may thus also raise food prices.
