    Abstract : The mobile industry is preparing to scale up the network capacity by a factor of 1000x in order to cope with the staggering growth in mobile traffic. As a consequence, there is a tremendous pressure on the network infrastructure, where more cost-effective, flexible, high speed connectivity solutions are being sought for. READ MORE

  4. 17. Univariate and Multivariate Surveillance of Outbreaks

    Author : Linus Schiöler; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; change-points; expected delay; exponential family; false alarms; generalised likelihood; inference principles; influenza; MEWMA; monitoring; multivariate; ordered regression; performance metrics; outbreak; predictive value; subjective judgment; spatial; statistical models; surveillance; tularemia;

    Abstract : In many areas there is a need to monitor observations in order to detect changes in the underlying processes as quickly as possible. The theory of statistical surveillance provides the possibility of making optimal decisions about whether a change has occurred or not based on the data available at the time of the decision.

  6. 19. Data driven modeling in the presence of time series structure: : Improved bounds and effective algorithms

    Author : Othmane Mazhar; Boualem Djehiche; Munther Dahleh; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Time series; Non-asymptotic estimation; Minimax; Change point detection; Hidden Markov model; State space model; Least square; Penalized Regression; Random covariance matrix; Concentration inequality; Chaining integral; Self-normalized martingale inequality; Cramér-Rao inequality; van Trees inequality; Matematisk statistik; Mathematical Statistics;

    Abstract : This thesis consists of five appended papers devoted to modeling tasks where the desired models are learned from data sets with an underlying time series structure. We develop a statistical methodology for providing efficient estimators and analyzing their non-asymptotic behavior. READ MORE

  7. 20. Monotonic and Semiparametric Regression for the Detection of Trends in Environmental Quality Data

    Author : Mohamed Hussian; Anders Grimvall; Ali Hadi; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Normalisation; Monotonic; Semiparametric; Temporal trends; fluctuations; global; local; Matematisk statistik; Icke-parametriska metoder; Statistics; Statistik;

    Abstract : Natural fluctuations in the state of the environment can long conceal or distort important trends in the human impact on our ecosystems. Accordingly, there is increasing interest in statistical normalisation techniques that can clarify the anthropogenic effects by removing meteorologically driven fluctuations and other natural variation in time series of environmental quality data.
