1. 1. The Uncertainty-Embedded Innovation Process : A study of how uncertainty emerges in the innovation process and of how firms address that to create novelty

   Författare :Sabrina Luthfa Karim; Gabriel Baffour Awuah; Mikael Hilmersson; Klaus Solberg Søilen; Anna Öhrwall Rönnbäck; Högskolan i Halmstad; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation process; Uncertainties; Compromised and uncompromised actions; Actors; Resources; Activities; Activity links; Activity void;

   Sammanfattning : Despite much discussion in the literature of uncertainties in relation to the innovation process, there is little knowledge of how they emerge in this process. This thesis accordingly aims to understand how uncertainty emerges in the innovation process and how firms address that uncertainty to create novelty from the process. LÄS MER

3. 2. Process Control and Simulation of Ferromagnetic Strip in the Power Transformers and Electrical Machines Applications : Electric power systems

   Författare :Kourosh Mousavi Takami; Jafar Mahmoudi; Örjan Danielsson; Mihai Nicolescu; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strip; electrical machines; transformer; cold rolling mills; process; automation; control; Band; elektriska maskiner; transformatorer; kallvalsningsverk; processautomation; reglerteknik; Electric power engineering; Elkraftteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : This thesis investigates optimization of the control of electrical and thermal equipment by using FEM and CFD modeling in combination with dynamic simulation models. The thesis focuses on the production of electrical strips and the control system with the aim of reducing losses and improving magnetic properties. LÄS MER

4. 3. Critical design activities in house-building projects : an industrial process perspective

   Författare :Martin Haller; Marcus Sandberg; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

   Sammanfattning : Dealing with planning accuracy respectively design errors is a big issue within construction. It has been argued that design errors are a major cause for waste in housing projects, despite all technical development. Reasons for design errors are well investigated and often relate to human acting. LÄS MER

5. 4. Decarbonising the Stainless Steelmaking through Alloy Solutions

   Författare :Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; optimization; raw material; process; quality; decarbonisation; rostfritt stål; optimering; material; process; kvalitet; avkarbonisering; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. LÄS MER

7. 5. Powder degradation during powder bed fusion processing

   Författare :Ahmad Raza; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser-based powder bed fusion; Alloy 718; Powder degradation; Oxidation; Electron beam powder bed fusion; Additive manufacturing; AlSi10Mg; Residual oxygen; Spatter particles; Sublimation.;

   Sammanfattning : Powder bed fusion (PBF) techniques, including laser-based powder bed fusion (LB-PBF) and electron beam powder bed fusion (EB-PBF), are two rapidly growing additive manufacturing (AM) processes due to their ability to produce complex geometries in near-net shapes. To attain reproducibility and repeatability in PBF processes, a consistent set of powder properties is vital. LÄS MER
