  1. 11. Radar Signal Processing using Artificial Neural Networks

    Författare :Alexander Karlsson; Magnus Jansson; Mikael Hämäläinen; Henrik Holter; Maria Sabrina Greco; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; artificial neural networks; classification; deep learning; detection; parameter estimation; radar; artificiella neuronnät; klassificering; djupinlärning; detektion; parameter estimering; radar; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis combines radar signal processing, with data driven artificial neuralnetwork (ANN) methods. Signal processing algorithms are often based on modelingassumptions of how the data was formed. In some cases, such models are sufficientfor designing good, or even optimal, solutions. LÄS MER

  3. 12. Order in the random forest

    Författare :Isak Karlsson; Henrik Boström; Lars Asker; Pierre Geurts; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Machine learning; random forest; ensemble; time series; data series; sequential data; sparse data; high-dimensional data; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : In many domains, repeated measurements are systematically collected to obtain the characteristics of objects or situations that evolve over time or other logical orderings. Although the classification of such data series shares many similarities with traditional multidimensional classification, inducing accurate machine learning models using traditional algorithms are typically infeasible since the order of the values must be considered.

  4. 13. Götisk kabbala och runisk alkemi : Johannes Bureus och den götiska esoterismen

    Författare :Thomas Karlsson; Erik af Edholm; Henrik Bogdan; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Western Esotericism; Gothicism; Kabbalah; Alchemy; The Swedish Great Power period; Millennialism; History of religion; Religionshistoria; History of Religion; religionshistoria;

    Sammanfattning : Gothicism in general, and the Swedish Gothicism in particular, had a close connection to the esoteric currents that were flourishing all over Europe in the Early Modern Period. Apocalyptic predictions and prophecies useful to Gothic propaganda were derived from contemporary esoteric streams, but alongside these came Hermetic and Neo-Platonic speculations of a more individual character that emphasized man’s gradual ascension toward a higher state.

  5. 14. Error and Traffic Control for High-Speed Networks

    Författare :Henrik Lundqvist; Gunnar Karlsson; Shivkumar Kalyanaraman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telecommunication; Telekommunikation;

    Sammanfattning : The Internet evolves rapidly, both in terms of the applications that use it and the networks that carry the traffic. This creates many important research tasks, both to adapt the networks that carry the traffic to work well together with the Internet protocols and to make the protocols robust to tolerate various underlying networks.

  7. 15. Prostate cancer : epidemiological studies of risk factors

    Författare :Camilla Thellenberg Karlsson; Beatrice Malmer; Henrik Grönberg; Anders Bergh; Peter Iversen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; epidemiology; SNP; BRCA2; male breast cancer; inflammation; BPH; P53; Oncology; Onkologi;

    Sammanfattning : In spite of the fact that prostate cancer is the most common male cancer in both Sweden and many other countries in the developed world, little is known of risk factors and predisposing conditions. The only well recognized risk factors are age, race and familial aggregation. LÄS MER
