  1. 1. Biomass conversion through syngas-based biorefineries : thermochemical process integration opportunities

    Author : Katarina Åberg; Anders Nordin; Linda Pommer; Erik Dahlquist; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; biorefinery; thermochemical conversion; torrefaction; slow pyrolysis; gasification; process integration; carbon negativity;

    Abstract : The replacement of fossil resources through renewable alternatives is one way to mitigate global climate change. Biomass is the only renewable source of carbon available for replacing oil as a refining feedstock. Therefore, it needs to be utilized not just as a fuel but for both biochemical and thermochemical conversion through biorefining. READ MORE

  2. 2. Design of Business Process Model Repositories : Requirements, Semantic Annotation Model and Relationship Meta-model

    Abstract : CO2 separation plays a vital role in reducing CO2 emissions to combat climate change, in which solvent-based absorption is widely considered the most promising technology. Many conventional chemical and physical solvents have been introduced for CO2 separation, still facing challenges. READ MORE

  4. 4. Model-Driven Process Design : Aligning Value Networks, Enterprise Goals, Services and IT Systems

    Author : Erik Perjons; Paul Johannesson; Anders G. Nilsson; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; business process design; e-process design; model-driven methods; enterprise modelling; business modelling; enterprise goals; services; value networks; business-IT alignment; design science; Computer and systems science; Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : The purpose of business-IT alignment is to optimise the relation between business and IT in order to maximise the business value of IT. Successful business-IT alignment can be enabled by business processes and e-processes functioning as adaptive mediators between business and IT systems. READ MORE

  5. 5. Model driven process planning for machining : Theory, application and improved information standards for efficient product realization

    Author : Mikael Hedlind; Torsten Kjellberg; Fumihiko Kimura; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Process planning; modeling; ISO 10303; CADCAM; kinematics; Beredning; modellering; ISO 10303; CADCAM; kinematik; SRA - Production; SRA - Produktion;

    Abstract : Model driven process planning is a methodology that emphasizes the application of models to create, represent and use information of products, processes and resources. Industry today stores information in a fragmented manner, mainly document centered with the consequence of data duplication requiring comprehensive data management and maintenance. READ MORE
