  2. 1. Contralateral breast cancer : risk and prognosis

    Author : Maria E C Sandberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The objective of this thesis was to investigate different aspects of contralateral breast cancer. This disease is of increasing importance as the mortality of breast cancer is decreasing while the incidence remains very high, consequently the population at risk for non-simultaneous (metachronous) contralateral breast cancer is increasing.

  4. 2. Chloride initiated reinforcement corrosion in marine concrete

    Author : Paul Sandberg; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; w c ratio; cover thickness; chloride penetration; service life prediction; corrosion cells; chloride thresholds; field exposure tests; marine concrete; pozzolans; reinforcement corrosion; chloride binding; Building construction; Byggnadsteknik;

    Abstract : Factors affecting the total chloride threshold for initiation of pitting corrosion in reinforced concrete were investigated by means of field and laboratory exposure tests. Factors affecting the chloride penetration into concrete were also investigated by means of field tests. The thesis consists of a summary (86 p.) and 11 papers attached. READ MORE

  5. 3. Ambiguity Domain Definitions and Covariance Function Estimation for Non-Stationary Random Processes in Discrete Time

    Author : Johan Sandberg; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The ambiguity domain plays a central role in estimating the time-varying spectrum of a non-stationary random process in continuous time, since multiplication in this domain is equivalent with estimating the covariance function of the random process using an intuitively appealing estimator. For processes in discrete time there exists a corresponding covariance function estimator. READ MORE

  6. 4. Discrete Stochastic Time-Frequency Analysis and Cepstrum Estimation

    Author : Johan Sandberg; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ambiguity domain; time-frequency analysis; time-frequency representations; covariance function; non-stationary random processes; Speaker recognition; MFCC; cepstrum;

    Abstract : The theory of stochastic time-frequency analysis of non-stationary random processes has mostly been developed for processes in continuous time. In practice however, random processes are observed, processed, and interpreted at a finite set of time points. READ MORE

  7. 5. Analyses of genomic and gene expression signatures

    Author : Rickard Sandberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Microarray; comparative genomics; differential gene expression; cell lines; computational biology;

    Abstract : Biology has entered a challenging, information-intense period where computational experiments are complementing traditional experiments. A plethora of new techniques have allowed biological processes to be investigated on a global scale. READ MORE
