  2. 1. Acoustic source characterisation for non-linear in-duct sources

    Author : Fredrik Albertson; KTH; []
    Keywords : in-duct source; source characterisation; non-linear source; linearity test; hybrid method; IC-engine; muffler; coupling method;

    Abstract : Different ways to model acoustic in-duct sources have beenanalysed. Measurements were conducted on two diesel truckengines. It was found that for steady state oscillations, onecould linearise in the neighbourhood of a given linearisationpoint, i.e. READ MORE

  4. 2. Open Source Business Model : Balancing Customers and Community

    Author : Thomas Rosén; Staffan Brege; Anna Öhrwall-Rönnbäck; Stefan Hrastinski; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Open Source Software; Business Models; Strategic Management; Market Positioning; Resource Based View; Industrial engineering and economy; Industriell teknik och ekonomi;

    Abstract : Free and Open Source Software has not only increased researchers’ interest about community-driven software development, but lately, interest from commercial actors increased as well. In addition, some scientists have claimed that Open Source Software has entered a new phase: OSS 2.0. READ MORE

  5. 3. Response of glaciers to climate change : Mass balance sensitivity, sea level rise and runoff

    Author : Mattias de Woul; Regine Hock; Peter Jansson; Margareta Hansson; Roger J. Braithwaite; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; glacier; mass balance modelling; mass balance sensitivity; sea level rise; glacial runoff; Hofsjökull; Storglaciären; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

    Abstract : The purpose of this study is to enhance our understanding of the response of glaciers to climate change. Global sea level is affected by changes in glacier ice volume, and melt-water from glaciers is a principal water source in many regions. READ MORE

  6. 4. Analysis of fluoroalkyl sulfonamide (FASA) based copolymers : An indirect source of non-polymeric PFAS

    Author : Felicia Fredriksson; Leo W. Y. Yeung; Anna Kärrman; Ulrika Eriksson; Robert Letcher; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFAS; FASA-based copolymers; fluorine mass balance; EOF; sludge; TF; earthworm; exposure;

    Abstract : Per- and polyfluoroalkyl substances (PFAS) are an extensive group of anthropogenic compounds and are of global concern due to their negative effects on the environment and humans. Most environmental research reports non-polymeric PFAS, leading to a scarce understanding of polymeric PFAS, despite their large share on the global market. READ MORE

  7. 5. Tracing Copper from society to the aquatic environment : Model development and case studies in Stockholm

    Author : Qing Cui; Maria E. Malmström; Olle Wahlberg; KTH; []
    Keywords : diffuse source; source analysis; sediment pollution levels; urban lake; Copper; Stockholm archipelago; SFA; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Copper remains at elevated levels in the aquatic environment of Stockholm due to diffuse urban sources. Management of these diffuse sources requires their quantification but they cannot be measured directly by field observations. READ MORE
