  1. 31. Advancing the understanding of pilot ignition in dual fuel engines : Experimental and conceptual studies

    Författare :Menno Merts; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion engines; Dual fuel; RCCI; Pilot injection; renewable fuels; Conceptual model; LTC; Heavy duty; Marine; Start of combustion; Optical engine research;

    Sammanfattning : The energy transition is looking for new technologies to reduce CO2 emissions. One of the promising options is the dual fuel engine. In this concept, based on a diesel engine, a small pilot diesel injection is used to ignite a second fuel. LÄS MER

  3. 32. EVOX-CPS : A Methodology For Data-Driven Optimization Of Building Operation

    Författare :Mischa Schmidt; Christer Åhlund; Robert Brännström; Anett Schülke; Christian Becker; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cyber-Physical Systems; Existing Buildings; Predictive Control; Sustainable Development; Energy Efficiency; Pervasive Mobile Computing; Distribuerade datorsystem;

    Sammanfattning : Existing building stock’s energy efficiency must improve due to its significant proportion of the global energy consumption mix. Predictive building control promises to increase the efficiency of buildings during their operational phase and thus lead to a reduction of the lion’s share of buildings’ lifetime energy consumption.

  4. 33. Chemical and Biochemical Biorefineries in Kraft Pulp Mills – Process Integration and Economics for Three Concepts

    Författare :Valeria Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bottleneck; ethanol; biorefinery; energy efficiency; process integration; pulp mill; high gravity;

    Sammanfattning : Some of the advantages of integrating biorefinery concepts with kraft pulp mills are that the utility system can be shared and that mass and energy streams can be exported from the pulp mill to the biorefinery or vice versa. These measures may result in lower investments and operating costs for the biorefinery compared with stand-alone operations. LÄS MER

  5. 34. Designing Electricity Distribution Network Charges for an Efficient Integration of Distributed Energy Resources and Customer Response

    Författare :Ibtihal Abdelmotteleb; Tómas Gómez; Javier Reneses; Rafael Cossent Árin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; customer response; distributed energy resources; distribution network charges; local flexibility mechanisms; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : A significant transformation has been gradually taking place within the energy sector, mainly as a result of energy policies targeting environmental objectives. Consequently, the penetration of Distributed Energy Resources (DERs) has been escalating, including self-generation, demand side management, storage, and electrical vehicles. LÄS MER

  7. 35. Essays on Productive Efficiency, Shadow Prices, and Human Capital

    Författare :Per-Olov Marklund; Thomas Aronsson; Chuan-Zhong Li; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; directional output distance function; Porter hypothesis; Burden-Sharing Agreement; Producer Responsibility Ordinance; Output of the educational sector; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : This thesis consists of five papers, four of them basically concerning environmental issues, while the fifth paper addresses the issue of measuring output from the educational sector. The first paper starts from the fact that industrial activity causes environmental damage. LÄS MER
