Sammanfattning : With so much focus on change and transformation in the organizing of projects, stability is commonly separated from change and relegated to be a static characteristic. This gives the impression that stability is not even a part of the process of organizing a project. LÄS MER
Sammanfattning : Metal laser powder bed fusion (L-PBF) allows for production of complex components using the energy from a laser to locally melt micron-sized powder following a layer-wise approach. Considerable scientific efforts are focused on addressing the influence of the process parameters on the melting stability and the control of material properties, while developing necessary monitoring and characterization tools.

Sammanfattning : The production of ethanol and other sustainable products including methane, limonene and pectin from citrus wastes (CWs) was studied in the present thesis. In the first part of the work, the CWs were hydrolyzed using enzymes – pectinase, cellulase and β-glucosidase – and the hydrolyzate was fermented using encapsulated yeasts in the presence of the inhibitor compound ‘limonene’.

Sammanfattning : Laser-Powder Bed Fusion (L-PBF) is an Additive Manufacturing (AM) technique that allows to produce near-net shape components of complex design. Applied to metallic materials, L-PBF allows to consolidate subsequent layers of powder using the heat from laser radiation. LÄS MER
Sammanfattning : In this thesis the stability of generic boundary layer flows is studied from a global viewpoint using optimization methods. Global eigenmodes of the incompressible linearized Navier-Stokes equations are computed using the Krylov subspace Arnoldi method. LÄS MER
