  1. 26. Capturing continuous human movement on a linear network with mobile phone towers

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Jesper Dejby; [2017]
    Keywords : Mobile phone tower analysis; Mobile phone networks; Spatial point processes; Linear networks; Call detail records; Human movement; Human trajectories; Markov decision processes; Continuous random walks;

    Abstract : Anonymous Call Detail Records (CDR’s) from mobile phone towers provide a unique opportunity to aggregate individual location data to overall human mobility patterns. Flowminder uses this data to improve the welfare of low- and middle-income countries. The movement patterns are studied through key measurements of mobility. READ MORE

  3. 27. Numerical Simulations of Linear Stochastic Oscillators : driven by Wiener and Poisson processes

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : André Berglund; [2017]
    Keywords : ;

    Abstract : The main component of this essay is the numerical analysis of stochastic differential equations driven by Wiener and Poisson processes. In order to do this, we focus on two model problems, the geometric Brownian motion and the linear stochastic oscillator, studied in the literature for stochastic differential equations only driven by a Wiener process.

  4. 28. Modeling market activity using 1D non-homogeneous Hawkes Processes

    University essay from Lunds universitet/Matematisk statistik

    Author : Eskil Andersson; [2017]
    Keywords : Mathematics and Statistics;

    Abstract : This paper can be seen as a light introduction to the study of Hawkes pro- cesses and their applicability in the realms of finance. In particular, this paper is concerned on the topic of modeling market activity and elaborates on how Hawkes processes are superior to non-homogeneous Poisson processes in this re- gard. READ MORE

  5. 29. Small Cohort Population Forecasting via Bayesian Learning

    University essay from KTH/Matematisk statistik

    Author : Simon Vallin; [2017]
    Keywords : ;

    Abstract : A set of distributional assumptions regarding the demographic processes of birth, death, emigration and immigration have been assembled to form a probabilistic model framework of population dynamics. This framework was summarized as a Bayesian network and Bayesian inference techniques are exploited to infer the posterior distributions of the model parameters from observed data. READ MORE

  6. 30. Snytbagge på brända och obrända kalhyggen

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Erik Fernemar; [2016]
    Keywords : Hylobius abietis; brand; hyggesbränning; kalhyggen;

    Abstract : I dagens skogsbruk har större skogsägare en typ av certifiering som kallas för FSC (Forest Stewardship Council). Denna standardkvalificering ger olika krav på miljö, skogsbruk och socialstandard som skogsägaren måste uppfylla för att certifieringen skall gälla. READ MORE
