  1. 1. Feature Selection for Microarray Data via Stochastic Approximation

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Erik Rosvall; [2024-03-18]
    Nyckelord :feature selection; feature ranking; microarray data; stochastic approximation; Barzilai and Borwein method; Machine Learning; AI;

    Sammanfattning : This thesis explores the challenge of feature selection (FS) in machine learning, which involves reducing the dimensionality of data. The selection of a relevant subset of features from a larger pool has demonstrated its effectiveness in enhancing the performance of various machine learning algorithms. LÄS MER

  3. 2. Utvärdering av biotopvårdande åtgärder i Grimåsbäcken. En analys av fysikaliska egenskaper och sammansättning av makroevertebrater.

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Björn Andermo; [2024-01-22]
    Nyckelord :Channelized streams; retention; biotope preservation; macroinvertebrates; bottom substrate; woody debris.;

    Sammanfattning : Many streams have been exposed to extensive anthropogenic impact for the benefit of forestry and agriculture. The effects has mainly been channelization characterized by lowered and straightened channels. This homogeneous morphology leads to decreased ability to retain water as well as lost connection to the floodplain. LÄS MER

  4. 3. OPTIMIZATION OF CLONE SELECTION PLATFORM FOR PRODUCTION OF RECOMBINANT PROTEINS

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Basel Yousef; [2024]
    Nyckelord :;

    Sammanfattning : Background  Biologics are type of proteins that can be produced by expression in a foreign host for medical healthcare applications in humans. Monoclonal antibodies (mAbs) are type of biologics that are designed to specifically bind to one target, with a purpose to inhibit a certain molecule that could be associated with a disease process.

  5. 4. Wireless Sensor Network for Controlling the Varroasis Spread within Bee colonies across a Geographical Region

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Venkat Sai Akhil Dasyam; Saketh Pokuri; [2024]
    Nyckelord :Wireless Sensor Networks; Monitoring and Control; Precision Beekeeping; Disease spread; Internet of Things.;

    Sammanfattning : Background: With the global decline of honey bee populations, safeguarding these vital pollinators has become crucial. Varroa destructor mites are a primary threat, weakening bees and facilitating the spread of diseases, which can decimate colonies and disrupt ecosystems. LÄS MER

  7. 5. Stamskador och dess uppkomst vid mekaniserad kvalitetsgallring i norra Sverige

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Lovisa Hansén; [2024]
    Nyckelord :skördare; faktorer; gallringskvalitet;

    Sammanfattning : Gallring är ett ingrepp som görs i ett skogsbestånd med syfte att ta bort ett urval av träd för att gynna de kvarstående, samt att ge en intäkt i form av virke. Som skogsägare kan man prioritera vilka värden man vill gynna i sin skog; ekonomiska, sociala och/eller biologiska. LÄS MER
