  1. 16. Design flood estimation under uncertainty

    Författare :Kenechukwu Okoli; Giuliano Di Baldassarre; András Bárdossy; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dimensionerande flöden; osäkerheter; avrinningsmodellering; frekvens analys.; Dimensionerande flöden; osäkerheter; avrinningsmodellering; frekvens analys.; Design flood; uncertainty; rainfall-runoff; frequency analysis.; Hydrology; Hydrologi;

    Sammanfattning : Att bestämma dimensionerande flöden, d.v.s. sannolikheten för att vat-tenföringen i ett vattendrag överskrider ett givet värde, är ett allmänt hydrologiskt problem som exempelvis används för att utvärdera över-svämningsrisker i vattendrag samt för att dimensionera hydrauliska kon-struktioner.

  3. 17. Computerized achievement tests : sequential and fixed length tests

    Författare :Marie H. Wiberg; Hans Nyquist; Ulf Olsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; item respons theory; sequential analysis; statistical inference; power; optimal design; simulations; Statistik; Statistics; Statistik; Statistics; statistik;

    Sammanfattning : The aim of this dissertation is to describe how a computerized achivement test can be constructed and used in practice. Throughout this dissertation the focus is on classifying the examinees into masters and non-masters depending on their ability. However, there has been no attempt to estimate their ability. LÄS MER

    Sammanfattning : With societies aging all around the world, the global burden of degenerative diseases is expected to increase exponentially. From the perspective drug development, degenerative diseases represent an especially challenging class. LÄS MER

  5. 19. Design and Security Analysis of TRNGs and PUFs

    Författare :Yang Yu; Elena Dubrova; Zhonghai Lu; Ilia Polian; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cryptographic primitive; Physical Unclonable Function; True Random Number Generator; Hardware security; Side-channel analysis; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : True Random Number Generators (TRNGs) and Physical Unclonable Functions (PUFs) are two important types of cryptographic primitives. TRNGs create a hardware-based, non-deterministic noise that is often used for generating keys, initialization vectors, and nonces for various applications that require cryptographic protection.

  7. 20. The MHC-glycopeptide-T cell interaction in collagen induced arthritis : a study using glycopeptides, isosteres and statistical molecular design in a mouse model for rheumatoid arthritis

    Författare :Lotta Holm; Jan Kihlberg; Morten Grötli; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rheumatoid arthritis; collagen; T-cell; class II MHC; solid phase peptide synthesis; glycopeptide; peptide isostere; PCA; statistical molecular design; PLS; QSAR; sequence binding motif; Organic chemistry; Organisk kemi;

    Sammanfattning : Rheumatoid arthritis (RA) is an autoimmune disease affecting approximately 1% of the population in the western world. It is characterised by a tissue specific attack of cartilage in peripheral joints. Collagen induced arthritis (CIA) is one of the most commonly used animal models for (RA), with similar symptoms and histopathology. LÄS MER
