  1. 1. On Degree Variance in Random Graphs

    Författare :Jan Hagberg; Ove Frank; Tom A.B. Snijders; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Degree Sequences; Uniform Random Graphs; Bernoulli Graphs; Degree Moments; Degree Statistics; Degree Variance; Gamma Approximation; Centrality Testing; Integer Sequences; Statistics; Statistik;

    Sammanfattning : This thesis is concerned with degree moments and degree variance in random graphs. The degree of vertex i in a graph is the number of edges incident to vertex i.In the first paper, degree moments and functions of degree moments are investigated for three random graph models.

  3. 2. Essays on statistical testing using Wavelet methodologies

    Författare :Yushu Li; Ghazi Shukur; Håkan Locking; Golam B. M. Kibria; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of five essays on the application of wavelet methodology to different tests in time series analysis. Essay I proposes a nonlinear Dickey-Fuller F test for unit roots against the first order Logistic Smooth Transition Autoregressive LSTAR (1) model. LÄS MER

  4. 3. Self-sampling for HPV testing in primary cervical screening : Including clinical and health economic aspects

    Författare :Riina Aarnio; Matts Olovsson; Ulf B. Gyllensten; Ingrid Wikström; Christer Borgfeldt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HPV; self-sampling; cervical screening; CIN2 ; cost-effectiveness; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Persistent infection with high-risk human papillomavirus (HPV) is a prerequisite for the development of cervical cancer. HPV testing has higher sensitivity for high-grade cervical intraepithelial neoplasia (CIN2+) than cytology, resulting in more effective screening. LÄS MER

  5. 4. Demonstrating reliableinstrumentation in theATLAS Tile Calorimeter : Fault tolerance and redundancy in hardware and firmwarefor the Phase-II Demonstrator project in preparation forHigh Luminosity LHC at CERN

    Författare :Henrik Åkerstedt; Samuel B. Silverstein; Jón E. Gudmundsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CERN; ATLAS; Tile calorimeter; TileCal; FPGA; SEU; TMR; Kintex; Demonstrator; DaughterBoard; Radiation testing; Radiation tolerant; Physics; fysik;

    Sammanfattning : The Large Hadron Collider at CERN is scheduled to undergo upgrades in 2026-2028 to significantly increase its luminosity. These upgrades, while providing the experiments with a higher collision rate, pose a number of challenges to the design of the hardware and software in the detectors. LÄS MER

  7. 5. Computational Analysis of Carbohydrates : Dynamical Properties and Interactions

    Författare :Robert Eklund; Göran Widmalm; Sören B. Engelsen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrate; DFT; ab initio; docking calculations; Molecular dynamics; Langevin Dynaimcs; structure analysis; carbohydrate-protein interaction; Chemical shift calculations; Spin spin coupling constants.; Organic chemistry; Organisk kemi;

    Sammanfattning : In this thesis a computational complement to experimental observables will be presented. Computational tools such as molecular dynamics and quantum chemical tools will be used to aid in the interpretation of experimentally (NMR) obtained structural data. LÄS MER
