    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system collaboration; District heating; Industrial excess heat; Combined heat and power; Energy system optimization; Metamodeling; Building LCC optimization; Building energy simulation; Cluster energy renovation; Energisystemsamverkan; Fjärrvärme; Industriell överskottsvärme; Kraftvärme; Energisystemoptimering; Metamodellering; Byggnads-LCC-optimering; Byggnadsenergisimulering; Klusterenergirenovering; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : With joint commitments by twenty-seven countries under the Paris Agreement, the European Union envisioned a resource-efficient and competitive economy without net emission of greenhouse gases by 2050. Immediate and massive efforts across sectors of energy, industry, and buildings will be required, and district heating (DH), through its ability to integrate efficiency measures on the supply and demand side, can play a central role.

    Författare :Olutayo Adegoke; Joel Andersson; Robert Pederson; Moataz Attallah; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser powder bed fusion; Alloy 247LC; additive manufacturing; nickel-based superalloys; processability; cracks; voids; Laserpulverbäddssmältning; legering 247LC; additiv tillverkning; superlegeringar; processbarhet; sprickor; porositet.; Production Technology; Produktionsteknik;

    Sammanfattning : This thesis is about laser powder bed fusion (L-PBF) of the nickel-basedsuperalloy Alloy 247LC. Alloy 247LC is mainly used in gas turbine blades and processing the blades with L-PBF may confer performance advantage over the blades manufactured with conventional methods. LÄS MER

    Sammanfattning : The focus of this work is on the experimental techniques and data analysis in atomic spectroscopy. Improved methods for the analysis of spectra and the determination of level energies are presented. Most of these are based on a rigorous statistical treatment of the spectroscopic data. LÄS MER

  7. 5. Simulation and Evaluation of Urban Rail On-board Crowding

    Författare :Soumela Peftitsi; Erik Jenelius; Oded Cats; Andreas Tapani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportsystem; Transport Systems;

    Sammanfattning : As travel demand grows in many metropolitan areas, overcrowding in public transport systems has become a major issue. Crowding distribution can be highly uneven over station platforms and multi-car transit vehicles. This implies that cars are not equally utilized and thus, passengers perceive on-board crowding higher. LÄS MER
