  1. 11. OAP: An efficient online principal component analysis algorithm for streaming EEG data

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Abdulghani Ismail Zubeir; [2018]
    Keywords : ;

    Abstract : Data processing on streaming data poses computational as well as statistical challenges. Streaming data requires that data processing algorithms are able to process a new data point within micro-seconds. READ MORE

  3. 12. Multi-Stage Network Processor for an Independent HVDC grids Supervisory Control

    University essay from KTH/Industriella informations- och styrsystem

    Author : Alessio Tonti; [2015]
    Keywords : ;

    Abstract : This thesis presents a Multi-Stage Network Processor as part of independentsupervisory control in HVDC grid connecting AC areas.The proposed Network Processor finds the topology of the grid building the AdjacencyMatrix, identifies islands and assigns DC slack bus. READ MORE

  4. 13. Semi-Analytical Finite Element method for guided waves in civil engineering plate-like structures

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Christian Nielsen; [2015]
    Keywords : seismics; structural health monitoring; lamb waves; SAFE; semi analytical finite element; wave guide finite element; non destructive testing; civil engineering; ultrasound; ultrasonography; comsol; wave guide; plate; Technology and Engineering;

    Abstract : Guided waves have a signicant potential for Structural Health Monitoring (SHM) and Non-Destructive Testing (NDT) due to their relatively long distance of propagation and sensitivity to discontinuities along the propagation path, anywhere through the material thickness. The inability to model wave guides of arbitrary cross-section using current matrix methods, has led to the development of a technique called Semi-Analytical Finite Element (SAFE). READ MORE

  5. 14. Return Models and Covariance Matrices

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Xiaolei Xie; [2014]
    Keywords : returns; stochastic volatility; GARCH; covariance matrix; random matrix; spectral distribution; Physics and Astronomy;

    Abstract : Return models and covariance matrices of return series have been studied. In particular, GARCH and SV models are compared with respect to their forecasting accuracy when applied to intraday return series. SV models are found to be considerably more accurate and more consistent in accuracy in forecasting. READ MORE

  6. 15. Evaluation of MIMO Non- Stationarity

    University essay from KTH/Signalbehandling

    Author : Omar Aldayel; [2011]
    Keywords : ;

    Abstract : The transmission performance of MIMO systems can be highly improved under stationary channel conditions where the channel statistics are constant. Unfortunately, mobile radio channels are not stationary all the time. Instead, they are stationary for finite time durations, so-called the stationarity regions. READ MORE
