  1. 1. Circling the Squares : Radical Innovation and Management Control Systems in the Circular Economy

    Författare :Johan Arekrans; Sofia Ritzén; Rafael Laurenti; Johan Frishammar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; circular economy; innovation; innovation management; sustainability; management control systems; cirkulär ekonomi; innovation; innovationsledning; hållbarhet; kontrollmekanismer; Machine Design; Maskinkonstruktion;

    Sammanfattning : An economic system built upon the sale of tangible goods produced using finite resources is inherently unsustainable. The idea of a Circular Economy (CE) as a viable pathway to sustainability has gained considerable attention from academia, policymakers, and the business community. LÄS MER

  3. 2. Designing for Change in Complex Systems : Design Considerations for Uptime in a Transportation System with Driverless Vehicles

    Författare :Lina Rylander; Jonas Mårtensson; Magnus Eneberg; Josina Vink; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Machine Design; Maskinkonstruktion;

    Sammanfattning : The transportation system is undergoing a transformation to enable socially, environmentally, and economically sustainable transport solutions, and driverless trucks are considered one innovation that can contribute to a more sustainable and efficient transportation system. Nevertheless, introducing driverless trucks will cause disruptions in the system, and one considerable change is that the driver is no longer present. LÄS MER

  4. 3. Sustainable Lubrication and Tribotronics enabled by Ionic Materials

    Författare :Akepati Bhaskar Reddy; Sergei Glavatskih; Mark W. Rutland; Nicholas Spencer; KTH; []

  5. 4. Exploring affordability in concept generation for complex defence products

    Författare :Daniel Amann; Mats Magnusson; Ingrid Kihlander; Poul Kyvsgaard Hansen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Affordability; complex product systems; concept generation; CoPS; defence; front end of innovation; innovation management; product development; tournament goods; Machine Design; Maskinkonstruktion;

    Sammanfattning : National defence budgets face pressure from intergenerational escalating costs for complex defence products, such as fighter aircraft and submarines. These escalating costs originate from ever-increasing performance requirements due to the competitive nature of warfare. In combat, only winning is good enough. LÄS MER

  7. 5. An experimental investigation of spur gear efficiency and temperature : A comparison between ground and superfinished surfaces

    Författare :Martin Andersson; Ulf Olofsson; Bengt-Göran Rosén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gears; ground; superfinished; efficiency; temperature; running-in; dip lubrication; spray lubrication; Machine Design; Maskinkonstruktion;

    Sammanfattning : This thesis focuses on reliability when testing gear efficiency and on how gear mesh efficiency can be increased without detrimental effects on the gears. Test equipment commonly used in gear research was analysed to identify important parameters for gear efficiency testing. LÄS MER
