  1. 16. Potassium in the Galactic thin and thick discs

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Carina Norregaard; [2018]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : To understand the evolution of our galaxy, the chemical abundance patterns and trends within the stars of the different regions are explored. The process of synthesizing these elements reveals key details about the way the stars and, therefore, the galaxy formed. LÄS MER

  3. 17. Can planet formation explain the observed differences in the chemical composition of binary stars?

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Rebecca Forsberg; [2017]
    Nyckelord :binary stars; planet formation; protoplanetary disc; Physics and Astronomy;

    Sammanfattning : A suggested explanation for the observed differences in chemical abundances in binary stars has been planet formation (e.g. Tucci Maia et al. 2014). LÄS MER

  4. 18. PDF document search within a very large database

    Kandidat-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Lizhong Wang; [2017]
    Nyckelord :Portable Document Format; Search; Document Identification; Cosine Similarity; Document Preprocessing; Document Search; Optimization Method; Performance Analysis; Classification; Regression; Loredge.; Portable Document Format; Sökning; Dokument Identifiering; Cosine Similarity; Dokument Förhandling; Dokument Sökning; Optimering metod; Prestandaanalys; Klassificering; Regression; Loredge;

    Sammanfattning : Digital search engine, taking a search request from user and then returning a result responded to the request to the user, is indispensable for modern humans who are used to surfing the Internet. On the other hand, the digital document PDF is accepted by more and more people and becomes widely used in this day and age due to the convenience and effectiveness. LÄS MER

  5. 19. Chemical composition of giant planet hosts

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Frida Ekstrand; [2017]
    Nyckelord :chemical composition; planet hosts; stellar twins; differential abundance analysis; Physics and Astronomy;

    Sammanfattning : Does the formation of planets give imprints on the chemical composition of the host star? In order to test this theory a differential abundance analysis (i.e. comparing two stars' abundances to each other) was carried out on a few stars with and without known planets, to see if any differences were found.

  7. 20. Fingerprint Matching using Small Sensors

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Rikard Drugge; [2017]
    Nyckelord :SVM; S3VM; SMOTE; ADASYN; filter; noise; fingerprint; small sensor; machine learning; Mathematics and Statistics;

    Sammanfattning : Fingerprint software is widely used in applications such as smartphones. There has to be some overlap between two fingerprint samples in order for them to be considered as belonging to the same finger. LÄS MER
