    Sammanfattning : The purpose of this thesis was to develop an economical, sustainable, and environmentally friendly straw Medium Density Fibreboard (MDF) process, capable of full-scale manufacturing and to produce MDF of requested quality. The investigated straw was based on wheat (Triticum aestivum L.) and rice (Oryzae sativa L.). LÄS MER

  3. 3. Characteristics of cast aluminium-silicon alloys : microstructures and mechanical properties

    Författare :Salem Seifeddine; Birger Karlsson; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Aluminium; Mocrostructure; Porosity; Tensile properties; Modelling; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik; Aluminium; microstructure; porosity; tensile properties; modelling.; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Applications of aluminium alloys are spreading in many industrial fields due to the excellent combination of castability, mechanical performance and lightness assured by such material. This project aims to establish a methodology in bringing the foundry process closer to the casting designer, and thereby leading to a more reliable and more optimised design. LÄS MER

  4. 4. Opportunities and uncertainties in the early stages of development of CO2 capture and storage

    Författare :Mårten Lind; Mats Westermark; Mohsen Assadi; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acceptance; cement; CCS; CO2 capture and storage; early opportunities; enhanced oil recovery; expert opinions; hybrid power cycles; optimism; oxyfuel combustion; pressurised fluidised bed combustion; pilot plant; potassium carbonate; risk; Sargas; scenario studies; scientific uncertainty; stakeholder perceptions; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik;

    Sammanfattning : The topic of this thesis is carbon dioxide (CO2) capture and storage (CCS), which is a technology that is currently being promoted by industries, scientists and governments, among others, in order to mitigate climate change despite a continued use of fossil fuels. Because of the complex nature of CCS and the risks it entails, it is controversial. LÄS MER

  5. 5. Inventory control and scheduling problems in a single-machine multi-item system

    Författare :Pär Brander; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

    Sammanfattning : This Doctoral Thesis addresses the topic of inventory control and scheduling in a single-machine multi-item system. Specifically, it considers a group of items processed, one at a time, on a single facility. Single-machine multi-item systems occur frequently in practice and apply both in continuous flow processes and batch flow processes. LÄS MER
