  1. 1. A Hierarchical Tucker Solver for the Vlasov-Maxwell System

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Oskar Tegby; [2023]
    Keywords : ;

    Abstract : The Vlasov-Maxwell equations is a common model to describe the behavior of a plasma, but come at the cost of their dimensionality since both spatial and veloocity data is stored in three dimensions. This causes a significant obstacle to be able solve them numerically since the size of the data is N^6, which yields a data size of 8. READ MORE

  3. 2. A Study on Data-driven Methods for Selection and Evaluation of Beam Subsets in 5G NR

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

    Author : Nic Ekman; Ilias Theodoros Skordas; [2022]
    Keywords : 5G; NR; telecom; telecommunications; ML; machine learning; algorithms; beam; widebeam; propagation; beamforming; subset; RAN; radio; radio environment; ericsson; Technology and Engineering;

    Abstract : 5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years.

  4. 3. The distribution of Foreigners and Locals in Sweden

    University essay from Högskolan i Jönköping/Internationella Handelshögskolan

    Author : Davide Dutto; Duyun Lei; [2020]
    Keywords : Agglomeration; Zipf’s law; Rank size distribution; Migration; Population;

    Abstract : This study aims to find a relationship between the distribution of locals inside of Sweden and the municipalities’ relative concentration of foreigners. With the usage of data found in the website Statistics Sweden, we aim to investigate the existence of any relationship between the local population size of a municipality against the number of foreigners present in said municipalities, and see whether foreigners and immigrants are more concentrated in more populated municipalities rather than less populated ones.

  5. 4. Maintaining Stream Data Distribution Over Sliding Window

    University essay from Mittuniversitetet/Avdelningen för informationssystem och -teknologi

    Author : Jian Chen; [2018]
    Keywords : Datastream; online algorithm; quantile problem; online analysis;

    Abstract : In modern applications, it is a big challenge that analyzing the order statistics about the most recent parts of the high-volume and high velocity stream data. There are some online quantile algorithms that can keep the sketch of the data in the sliding window and they can answer the quantile or rank query in a very short time. READ MORE

  6. 5. Evaluating habitat suitability and spectral heterogeneity models to predict weed species presence

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Christina Fotiou; [2014]
    Keywords : GARP; herbicide resistant weeds; climate change; spatial heterogeneity; habitat; regression; NDVI; Physical Geography and Ecosystem Analysis; GIS; Earth and Environmental Sciences;

    Abstract : The aim of this study is to analyze whether the presence of weed species resistant to herbicides is related to landscape heterogeneity and environmental variables. C3 and C4 weed species, such as Chenopodium album, Conyza canadensis, Amaranthus retroflexus, Papaver rhoeas, Sorghum halepense, Echinochloa crus-galli and Lolium rigidum, are studied in two differing bioclimatic countries, Greece and Germany.
