  1. 1. Analys av gener och arter i metagenomikdata

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Sofia Bäckström Lebens; Emma Eriksson; [2019-06-14]
    Nyckelord :;

    Sammanfattning : As new extreme high throughput DNA sequencing methods continue to develop thelarge amounts of information that they give rise to in terms of metagenomic data opensthe way for completely novel approaches to the study of microbial ecosystems. In thisproject we have investigated how relationships and connections between microbial genesand species that carry them can be found based entirely on their appearance in twoseparate datasets accumulated from the same samples using metagenomic analysis.

  2. 2. Deinterleaving pulse trains with DBSCAN and FART

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Shad Mahmod; [2019]
    Nyckelord :DBSCAN; FART; Fuzzy; Adaptive; Resonance; Theory; Radar; Clustering; Deinterleaving; Machine Learning;

    Sammanfattning : Studying radar pulses and looking for certain patterns is critical in order to assess the threat level of the environment around an antenna. In order to study the electromagnetic pulses emitted from a certain radar, one must first register and identify these pulses. LÄS MER

  3. 3. A Spatial Analysis of Homicide Crime’s Distribution and Association with Deprivation in Stockholm Between 2010-2017

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Dennis Lindell Schettini; [2019]
    Nyckelord :GIS; homicide; deprivation; hot spot; generalized regression; Earth and Environmental Sciences;

    Sammanfattning : A Spatial Analysis of Homicide Crime’s Distribution and Association with Deprivation in Stockholm Between 2010-2017 Homicide crimes are rare events depending on numerous factors and tend to be distributed differently based on geographic location. The use of spatial analysis is substantively important for detecting different predictors in varying geographic areas and for the diffusion process of homicide crimes. LÄS MER

  4. 4. Gamma Knife treatment planning with new degrees of freedom

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Emil Norell; [2019]
    Nyckelord :Stereotactic radiosurgery; Leksell Gamma Knife®; inverse planning; clustering; optimization; column generation; Stereotaktisk radiokirurgi; strålkniven; inversplanering; klustring; optimering; kolumn-generering;

    Sammanfattning : The Leksell Gamma Knife® is an instrument designed for high precision treatment of tumours and lesions located in the brain and upper spine. Today, the radioactive cobalt-60 sources can only move linearly along the radiation unit, but the machine could be modified to include rotational motion as well. LÄS MER

  5. 5. Cluster analysis on sparse customer data on purchase of insurance products

    Master-uppsats, KTH/Matematisk statistik

    Författare :Michel Alexander Postigo Smura; [2019]
    Nyckelord :;

    Sammanfattning : This thesis work aims at performing a cluster analysis on customer data of insurance products. Three different clustering algorithms are investigated. These are K-means (center-based clustering), Two-Level clustering (SOM and Hierarchical clustering) and HDBSCAN (density-based clustering). LÄS MER
