  • Mustonen, Pasi (2013-06-05)
    This thesis investigates how access control can be implemented in applications which utilize Linked Data. From the viewpoint of access control the relevant subject is, instead of Linked Open Data, specifically Linked Closed ...
  • Raitoharju, Matti; Ali-Löytty, Simo (2012)
    In the Gaussian mixture approach a Bayesian posterior probability distribution function is approximated using a weighted sum of Gaussians. This work presents a novel method for generating a Gaussian mixture by splitting ...
  • Kaatiala, Jussi (2013-01-09)
    Eräs tärkeimmistä aivojen tutkimusmenetelmistä on aivojen sähköisen toiminnan mittaaminen. Elektroenkefalografia (EEG) on tärkeä mittaväline aivojen valvetilan sekä dynaamisen tilan kuvaamisessa ja menetelmä on laajalti ...
  • Nurminen, Anssi (2013-05-08)
    Tables are an intuitive and universally used way of presenting large sets of experimental results and research findings, and as such, they are the majority source of significant data in scientific publications. As no ...
  • Liuttu, Janne (2012-10-03)
    Internetin räjähdysmäinen kasvu on tehnyt entistä suuremmaksi haasteeksi löytää merkitykselliset ja luotettavat sivustot harmaasta massasta. Tähän tarkoitukseen on kehitetty erilaisia arvostusalgoritmeja, joilla pyritään ...
  • Seppänen, Mari (2011)
    A method to predict satellite orbits in a GPS device without a network connection is presented. The motivation for this work was to improve the startup performance of a navigation device without Assisted GPS. Tests of our ...
  • Seppänen, Mari; Perälä, Tommi; Piché, Robert (2011)
    A method to predict satellite orbits in a GPS device without a network connection is presented. The motivation for this work was to reduce time to first fix when assistance data is not available. The orbit of a satellite ...
  • Pesonen, Henri (2013-02-08)
    Personal positioning is a dynamic estimation problem where the ability to assess the quality of the positioning service is as important as obtaining accurate position estimates. When estimating the position of a person, ...
  • Pesonen, Henri; Piché, Robert (2012)
    A novel approach for monitoring the accuracy of the Bayesian estimate of linear Gaussian state-space model is introduced, based on the monitoring of the propagation of the errors in the Kalman filter algorithm. The effect ...
  • Järvenpää, Marko (2013-03-06)
    The main motivation of this work is to review and extend some recent ideas in Bayesian inverse problems especially in the context of image processing problems. Often these problems are solved using deterministic optimisation ...
  • Pesonen, Henri; Piché, Robert (2011)
    Gaussian mixture models are often used in target tracking applications to take into account maneuvers in state dynamics or changing levels of observation noise. In this study it is assumed that the measurement or the state ...
  • Muller, Juliane; Kanniainen, Juho; Piche, Robert (2013)
    This paper investigates a global optimization algorithm for the calibration of stochastic volatility models. Two GARCH models are considered, namely the Leverage and the Heston-Nandi model. Empirical information on option ...
  • Huhtamäki, Jukka; Nykänen, Ossi; Salonen, Jaakko (2009)
    Modern Web introduces new means to support conference information retrieval and, moreover, social tools that enable conference delegates to actively contribute to a conference. Simultaneously, existing case studies show ...
  • Salonen, Jaakko; Huhtamäki, Jukka; Nykänen, Ossi (2013-10-01)
    Diverse data about various phenomena are implicitly available in the modern web. In particular websites categorized as social media provide rich and heterogeneous data about various entities such as people, corporations, ...
  • Minaev, Georgy (2012-12-05)
    The development of computers has enabled the collection and storage of terabytes of data and the creation of large data warehouses. The main problems with such data are their size and structure. The fundamental intellectual ...
  • Huhtamäki, Jukka; Salonen, Jaakko; Marttila, Jarno; Nykänen, Ossi (2010)
    Along social media and Web 2.0, the amount of data sources potentially available for social network visualisation has snowballed. Recent development on information visualisation technologies contribute to the availability ...
  • Nurmi, Juha (2013-05-08)
    Mekatronisen koneen suunnittelu vaatii useita teknologioita yhdistävää suunnittelutyötä. Yhteissuunnittelu toisi suunnittelijat yhteen suunnittelemaan kokonaista toimivaa laitetta yksittäisten suunnitteluteknologioiden ...
  • Ala-Luhtala, Juha; Seppänen, Mari; Piché, Robert (2012)
    GNSS satellite orbits can be predicted by integrating the satellites’ equation of motion. If the prediction is done in a consumer grade positioning device, a simplified version of the equation of motion is required. The ...
  • Ala-Luhtala, Juha; Seppänen, Mari; Ali-Löytty, Simo; Piché, Robert; Nurminen, Henri (2013)
    In self-assisted GNSS the orbit of a satellite is predicted by solving the differential equation that models its motion. Our motion model includes the most important forces: Earth's gravity, lunar and solar gravity and ...
  • Pesonen, Henri; Piche, Robert (2012-09)
    The variational Bayes method is applied to the state-space estimation problem with maneuvers or changes in the covariance of the observation noise. The resulting algorithm is an off-line batch method that can be used to ...
