    Abstract : Public transport plays a vital role in society as the economy, the degree of sustainability and the qualityof life of a city is directly affected by transportation. A shift in modal share towards public transport isassociated with many benefits such as increased air quality and improved space allocation within thecity. READ MORE

  4. 18. A comparative study on the unsupervised classification of rat neurons by their morphology

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

    Author : Sabrina Chowdhury; Added Kina; [2020]
    Keywords : ;

    Abstract : An ongoing problem regarding the automatic classification of neurons by their morphology is the lack of consensus between experts on neuron types. Unsupervised clustering using persistent homology as a descriptor for the morphology of neurons helps tackle the problem of bias in feature selection and has the potential of aiding neuroscience research in developing a framework for automatic neuron classification.

  5. 19. Hierarchical Clustering based Dynamic Subarrays for Hybrid Beamforming Massive MU-MIMO

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

    Author : Francisco Goncalves Contente; [2020]
    Keywords : ;

    Abstract : Hybrid Beamforming in multiple input multiple output systems has surged in the past few years as the prime precoding architecture for massive MIMO systems since it addresses the systems performance and complexity/power consumption tradeoff. Most of the literature addresses HBF MIMO with a fixed antenna subarray, however it is possible to further increase the spectral efficiency of the system by dynamically configuring the HBF MIMO subarray according the channel state information of the users.
