  1. 21. Machine Learning Based Stock Price Prediction by Integrating ARIMA model and Sentiment Analysis with Insights from News and Information

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Teja Sai Vaibhav Boppana; Joseph Sudheer Vinakonda; [2023]
    Keywords : Machine Learning; Market Trends; News; Headlines Stock Price Prediction; VADER.;

    Abstract : Background: Predicting stock prices in today’s complex financial landscape is asignificant challenge. An innovative approach to address this challenge is integrating sentiment analysis techniques with the well-established Autoregressive IntegratedMoving Average (ARIMA) model. READ MORE

  2. 22. Forced response numerical investigation of a transonic compressor rotor

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

    Author : Mariana Pires Gonçalves Toco Dias; [2023]
    Keywords : Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Abstract : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. READ MORE

  3. 23. Conform with the Wind : Processing short-term ensemble forecasts with conformal based methods for probabilistic wind-speed forecasting

    University essay from Lunds universitet/Matematisk statistik

    Author : Simon Althoff; [2023]
    Keywords : wind-speed; probabilistic; forecasts; forecasting; ensemble; post-processing; conformal prediction; conformal predictive systems; quantile regression forest; non-exchangeable; Mathematics and Statistics;

    Abstract : Forecasting wind has always been an interesting subject, and as large parts of the world are relying more on wind for power production it is becoming even more important to have reliable forecasts. Probabilistic forecasts, where distributions are predicted in contrast to deterministic forecasts, are impor- tant for informed decision making. READ MORE

  4. 24. Optimal Control of An Energy Storage System Providing Fast Charging and Ancillary Services

    University essay from KTH/Optimeringslära och systemteori

    Author : Max Völcker; Hugo Rolff; [2023]
    Keywords : Optimal Control; Model Predictive Control; Dynamic Programming; State-Space Representation; Monte Carlo Simulation; Frequency Regulation; Fast Charging; Energy Storage Systems; Net Present Value; Optimal styrteori; Modell-prediktiv reglering; Dynamisk programmering; Frekvensreglering; Snabbladdning; Energilager; Nuvärde;

    Abstract : In this thesis, we explore the potential of financing a fast charging system with energy storage by delivering ancillary services from the energy storage in an optimal way. Specifically, a system delivering frequency regulation services FCR-D Up and FCR-D Down in combination with energy arbitrage trading is considered. READ MORE

  5. 25. Predicting Chronic Kidney Disease using a multimodal Machine Learning approach

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Aakruti Mishra; Navaneeth Puthiyandi; [2023]
    Keywords : Chronic kidney disease; Multimodal approach; ROCKET; Random Forest; XGBoost; MIMIC-III database; Data imbalance; Temporal and static modalities; Soft voting;

    Abstract : Chronic Kidney Disease (CKD) is a common and dangerous health condition that requires early detection and treatment to be effective. Current diagnostic methods are time-consuming and expensive. In this research, we hope to construct a predictive model for CKD utilizing a combination of time series and static variables for early detection of CKD. READ MORE
