16. Deep Learning models for turbulent shear flow
University essay from KTH/Numerisk analys, NAAbstract : Deep neural networks trained with spatio-temporal evolution of a dynamical system may be regarded as an empirical alternative to conventional models using differential equations. In this thesis, such deep learning models are constructed for the problem of turbulent shear flow. READ MORE

17. An Application of the Continuous Wavelet Transform to Financial Time Series
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Wavelet theory, which shares fundamental concepts with windowed Fourier analysis, introduces the notion of scale in an effort to aid in joint time-frequency analysis. Having century-old roots, much of the essential research on the subject of wavelets was conducted during the 1970s and 1980s. READ MORE

18. An evaluation of deep neural network approaches for traffic speed prediction
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The transportation industry has a significant effect on the sustainability and development of a society. Learning traffic patterns, and predicting the traffic parameters such as flow or speed for a specific spatiotemporal point is beneficial for transportation systems. READ MORE

19. Finite Element Method for 1D Transient Convective Heat Transfer Problems
University essay from Linnéuniversitetet/Institutionen för matematik (MA)Abstract : We study heat transfer in one dimension with and without convection, also called advection-diffusion. This is done using the Finite Element Method (FEM) to discretise the mathematical model, i.e. the heat equation. READ MORE

20. Design and Fabrication of 1550 nm Photonic Crystal Surface Emitting Lasers
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In this study, the design and fabrication of a monolithic InP-based 1550-nm photonic-crystal surfaceemitting laser (PCSEL) is reported. The device is composed by an InGaAsP multi-quantum well (MQW) active layer and InP photonic crystal (PhC) formed by metal organic chemical vapour deposition (MOCVD). READ MORE
