  1. 1. On linear Reaction-Diffusion systems and Network Controllability

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Rebecka Aulin; Felicia Hage; [2023]
    Keywords : Turing s model of morphogenesis; FDM; FEM; Controllability; Minimal Control; Least Energy Control;

    Abstract : In 1952 Alan Turing published his paper "The Chemical Basis of Morphogenesis", which described a model for how naturally occurring patterns, such as the stripes of a zebra and the spots of a leopard, can arise from a spatially homogeneous steady state through diffusion. Turing suggested that the concentration of the substances producing the patterns is determined by the reaction kinetics, how the substances interact, and diffusion. READ MORE

  3. 2. Exploring the Possibilities of Sheet Metal Forming Via Plastic-Based Additive Manufacturing Moulding

    University essay from KTH/Produktionsutveckling

    Author : Jemal Idris Ismail; Kafeel Olanrewaju Sanni; [2023]
    Keywords : : Sheet metal formation; Additive manufacturing; mass customization; personalized production; die design; die system; FDM; DOE; FEA; product development; automotive; sustainability; cost effective; metal dies; plastic dies.; Plåtformning; Additiv tillverkning; massanpassning; personlig produktion; formdesign; formsystem; FDM; DOE; FEA; produktutveckling; fordonsindustri; hållbarhet; kostnadseffektiv; metallformar; plastformar.;

    Abstract : Additive Manufacturing (AM) has freeform fabrication capabilities of complex geometries directly from feedstock material. This can potentially enhance the efficient use of material and the cost effectiveness. It also offers design flexibility, and it is versatile. READ MORE

  4. 3. The processing of a 3d-printed biocomposite : A material driven study conducted in collaboration with Stora Enso

    University essay from Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

    Author : Jacob Zettersten; [2023]
    Keywords : 3d; biocomposite; FDM; additive manufacturing; processing;

    Abstract : This is a material driven study that explores how post-processing of a 3D-printed biocomposite may increase its utility in the public furniture industry. The study thereby aims to contribute insights in material development and inspire a shift in practices that pushes the industry towards a more sustainable design process. READ MORE

  5. 4. Input shaping in a cantilever 3D printer : Construction and evaluation

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Albert Achrén; Jacob Bårdén; [2023]
    Keywords : FDM; 3D printing; input shaping; cantilever; additive manufacturing; FDM; 3D Printing; inout shaping; fribärande; additiv tillverkning;

    Abstract : FDM 3D printing is an additive manufacturing technology that is widely used, mainly for rapid prototyping. It is also one of the cheapest and most accessible AM technologies for consumers. FDM printers, and especially cheaper alternatives, can have problems with creating high quality prints. READ MORE

  6. 5. Numerical Simulation of the Generalized Modified Benjamin-Bona-Mahony Equation Using SBP-SAT in Time

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Vilma Kjelldahl; [2023]
    Keywords : Benjamin-Bona-Mahony equation; non-linear; initial boundary value problem; summation-by-parts; simultaneous-approximation-term; time integration; simulation;

    Abstract : This paper describes simulations of the generalized modified Benjamin-Bona-Mahony (BBM) equation, using finite difference methods (FDM). Well-posed boundary conditions (BCs) as well as stable semi-discrete approximations are derived using summations-by-parts (SBP) operators combined with the projection method. READ MORE
