(201412)Proceedings of the Inverse Days 2014 conference organized in Tampere 9th  11th December 2014. This document contains the schedule of the conference, the list of participants and the abstracts of the talks given at the conference.

(20130605)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 ...

(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 ...

(20130109)Eräs tärkeimmistä aivojen tutkimusmenetelmistä on aivojen sähköisen toiminnan mittaaminen. Elektroenkefalografia (EEG) on tärkeä mittaväline aivojen valvetilan sekä dynaamisen tilan kuvaamisessa ja menetelmä on laajalti ...

(20130508)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 ...

(20150204)This thesis lays out a common architecture for a software system meant for verification of correctness of concurrent state machines. The purpose of the architecture is to enable implementation and combination of different ...

(20121003)Internetin räjähdysmäinen kasvu on tehnyt entistä suuremmaksi haasteeksi löytää merkitykselliset ja luotettavat sivustot harmaasta massasta. Tähän tarkoitukseen on kehitetty erilaisia arvostusalgoritmeja, joilla pyritään ...

(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 ...

(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 ...

(20130208)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, ...

(2012)A novel approach for monitoring the accuracy of the Bayesian estimate of linear Gaussian statespace model is introduced, based on the monitoring of the propagation of the errors in the Kalman filter algorithm. The effect ...

(20130306)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 ...

(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 ...

(2009)An integrity monitoring/failure detection and identification approach for GNSS positioning that is based on Bayesian model comparison theory is introduced. In the new method the user defines models for nofailure/failure ...

(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 HestonNandi model. Empirical information on option ...

(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 ...

(20131001)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, ...

(2009)The term “location fingerprinting” covers a wide variety of methods for determining receiver position using databases of radio signal strength measurements from different sources. In this work we present a survey of location ...

(20121205)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 ...

(20150204)The graph isomorphism problem is the computational problem of determining whether two ﬁnite graphs are isomorphic, that is, structurally the same. The complexity of graph isomorphism is an open problem and it is one of the ...
