  1. 11. Sequential Monte Carlo Methods with Applications to Positioning and Tracking in Wireless Networks

    Författare :Svetlana Bizjajeva; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; positioning; state-space models; SMCM; particle filtering;

    Sammanfattning : This thesis is based on 5 papers exploring the filtering problem in non-linear non-Gaussian state-space models together with applications of Sequential Monte Carlo (also called particle filtering) methods to the positioning in wireless networks. The aim of the first paper is to study the performance of particle filtering techniques in mobile positioning using signal strength measurements. LÄS MER

  3. 12. Hardware biases and their impact on GNSS positioning

    Författare :Martin Håkansson; Anna B. O. Jensen; Milan Horemuz; Jan Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GNSS positioning; Hardware biases; multi-GNSS; GPS; GLONASS; Galileo; BeiDou; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : GNSS hardware biases appear in code and phase observations, and originates both from the receiver and satellite hardware. These biases influence the accuracy in precise GNSS positioning if not handled properly. LÄS MER

  4. 13. ‘Collaborative Competition’ : Stance-taking and Positioning in the European Parliament

    Författare :Nazli Avdan; Leelo Keevallik; Angelika Linke; Frank Baasner; Jan Anward; John DuBois; Linköpings universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Parliamentary Interaction; Questions and Questioning; the European Parliament; Stancetaking; Intergroup Positioning;

    Sammanfattning : The European Parliament (EP) is the scene where certain issues concerning over 500 million ‘Europeans’ are publicly debated and where politically relevant groupings are discursively coconstructed. While the Members of the Parliament (MEPs) pursue their political agendas, intergroup boundaries are drawn, reinforced, and/or transgressed. LÄS MER

  5. 14. Languaging and Social Positioning in Multilingual School Practices : Studies of Sweden Finnish Middle School Years

    Författare :Annaliina Gynne; Pirjo Lahdenperä; Sangeeta Bagga-Gupta; Jarmo Lainio; Fritjof Sahlström; Mälardalens högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; languaging; social positioning; social interaction; sociocultural; dialogical; ethnography; bilingual education; multilingual; Sweden Finns; didaktik; Didactics;

    Sammanfattning : The overall aim of the thesis is to examine young people’s languaging, including literacy practices, and its relation to meaning-making and social positioning. Framed by sociocultural and dialogical perspectives, the thesis builds upon four studies that arise from (n)ethnographic fieldwork conducted in two different settings: an institutional educational setting where bilingualism and biculturalism are core values, and social media settings.

  7. 15. Physics-based modelling and measurement of advanced manufacturing machinery’s positioning accuracy : Machine tools, industrial manipulators and their positioning accuracy

    Författare :Nikolas Alexander Theissen; Andreas Archenti; Edward P. Morse; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine tools; Industrial robots; Accuracy; Measurement instruments; Production Engineering; Industriell produktion;

    Sammanfattning : Advanced manufacturing machinery is a corner stone of essential industries of technologicallydeveloped societies. Their accuracy permits the production of complexproducts according to tight geometric dimensions and tolerances for high efficiency,interchangeability and sustainability. LÄS MER
