  1. 16. Predicting the unpredictable - Can Artificial Neural Network replace ARIMA for prediction of the Swedish Stock Market (OMXS30)?

    University essay from Mittuniversitetet/Institutionen för ekonomi, geografi, juridik och turism

    Author : Alberto Ferreira de Melo Filho; [2019]
    Keywords : Artificial Neural Network; ARIMA; LSTM; stock market;

    Abstract : During several decades the stock market has been an area of interest forresearchers due to its complexity, noise, uncertainty and nonlinearity of thedata. Most of the studies regarding this area use a classical stochastics method,an example of this is ARIMA which is a standard approach for time seriesprediction. READ MORE

  3. 17. Reduction of Crosstalk Distortion in 5G

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Ali Al-Qamaji; Fida Abdalrahman; [2019]
    Keywords : Wireless Communication; Power Amplifier; Linearization; Digital predisposition; 5G; Massive MIMO.; Technology and Engineering;

    Abstract : Increasing demand for higher data rates in wireless communication systems has tremendously evolved over the last years. This demand is rapidly increasing with rising in number of wireless devices. READ MORE

  4. 18. The effects of backlash on the frequency stability in a hydro based power system

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Niklas Ung; [2018]
    Keywords : ;

    Abstract : The generated and consumed power should always be in balance in a power system. Any energy from a power imbalance will be stored as kinetic energy in the system's rotating mass leading to a changed frequency. To keep the frequency within acceptable limits hydropower plants are used to counteract power imbalances. READ MORE

  5. 19. Generalizing Deep Deterministic Policy Gradient

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gustaf Jacobzon; Martin Larsson; [2018]
    Keywords : ;

    Abstract : We extend Deep Deterministic Policy Gradient, a state of the art algorithm for continuous control, in order to achieve a high generalization capability. To achieve better generalization capabilities for the agent we introduce drop-out to the algorithm one of the most successful regularization techniques for generalization in machine learning.

  6. 20. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study

    University essay from KTH/Bro- och stålbyggnad

    Author : Turgay Dagdelen; Shaho Ruhani; [2018]
    Keywords : Soil-Structure Interaction; Railway Bridge; Portal Frame Bridge; Dynamic Analysis; Parametric Study; Nonlinear Analysis; Jord-struktur interaktion; Järnvägsbro; Plattrambro; Dynamisk analys; Parametrisk studie; Icke-linjär analys;

    Abstract : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.
