1. 16. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

   University essay from KTH/Materialvetenskap

   Author : Hagen Christian Hagens; [2022]
   Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

   Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

3. 17. Computation of Acoustic Wave Propagation Under Water

   University essay from KTH/Matematik (Avd.)

   Author : Frida Thörn; [2022]
   Keywords : Wave equation; Helmholtz equation; Waveholtz iteration; finite difference method; summation by parts; energy method; point source; curvilinear coordinates; vågekvationen; helmholtz ekvation; waveholtz iteration; finita differens methoden; energimetoden; punktkälla; kurvlinjära koordinater; kroklinjiga koordinater; SBP;

   Abstract : In this thesis we look at acoustic wave propagation under water. We look in particular at waves generated by a point source and what happens with the propagation when we model the bottom as flat or as curvilinear. We assume the source to be working at a certain frequency and therefore we model this problem by solving the Helmholtz equation. READ MORE

5. 19. Finite Difference Approximations for Wave Propagation

   University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

   Author : Sebastian Lindqvist; [2022]
   Keywords : Finite Difference; Maxwell’s equations; wave propagation; advection equation; partial differential equations;

   Abstract : Finite difference approximations are methods for solving differential equations by approximating derivatives. This work will begin with how to solve a partial differential equation (PDE) called the advection equation, ut + cux = 0. READ MORE

6. 20. Investigating the use of Semiconductor Nanowires for Neural Networks

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Alfredo Serafini; [2022]
   Keywords : FDTD method and simulation; optical broadcasting neural network; optical communication of nanowires; sub-wavelength absorption.; Physics and Astronomy;

   Abstract : In this work, we intend to employ nanowires for the realisation of an artificial neuron which can be used to design a neural network that will guide the new generation of non-von Neumann architectures such as Neuromorphic Computing. Possible applications are strongly related to Neuromorphic architectures and artificial intelligence, such as high-performance computers, robotics hardware and autonomous drones. READ MORE
