  2. 1. The Origin-Destination Matrix Estimation Problem : Analysis and Computations

    Author : Anders Peterson; Jan Lundgren; Torbjörn Larsson; Lars-Göran Mattsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Traffic modelling; Travel demand; Origin--Destination matrix; Traffic flow observation; Detector allocation; Estimation.; OD-matris; Trafikflödesobservation; Detektorallokering; Skattning; Trafikmodellering; Reseefterfrågan; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : For most kind of analyses in the field of traffic planning, there is a need for origin--destination (OD) matrices, which specify the travel demands between the origin and destination nodes in the network. This thesis concerns the OD-matrix estimation problem, that is, the calculation of OD-matrices using observed link flows. READ MORE

  4. 2. Objective Assessment of Loose Gravel Condition using Machine Learning with Audio-visual Observation

    Author : Nausheen Saeed; Moudud Alam; Roger G. Nyberg; Niklas Lavesson; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gravel road condition assessment; Loose gravel; Sound analysis; Machine learning; Image analysis; Audio analysis; Image and audio data fusion;

    Abstract : A well-maintained road network is essential for sustainable economic development, providing vital transportation routes for goods and services while connecting communities. Sweden's public road network includes a significant portion of gravel roads, particularly cost-effective for less populated areas with lower traffic volumes. READ MORE

  5. 3. The Construction of the Professional Identity of the TV News Presenter in Two Chinese News Programmes : A Discourse-Theoretical Analysis

    Author : Yiming Chen; Nico Carpentier; Göran Svensson; Benjamin De Cleen; Ike Picone; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Discourse theory; Discourse-theoretical analysis; the TV news presenter; professional identity construction; articulation; nodal points; Chinese journalistic practice; Medie- och kommunikationsvetenskap; Media and Communication Studies;

    Abstract : This PhD research project investigates how the professional identity of the Chinese TV news presenter is constructed in two news programmes, Guangdong News and TVS News, both based at Guangdong TV. The overarching theoretical framework of the project takes its inspiration from Laclau and Mouffe's (1985) post-structuralist discourse theory (DT). READ MORE

  6. 4. Structural-acoustic vibrations in wooden assemblies : Experimental modal analysis and finite element modelling

    Author : Åsa Bolmsvik; Torbjörn Ekevik; Andreas Linderholt; Anders Brandt; Anders Ågren; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wooden framed structure; light weight buildings; multi-storey; flanking transmission; junction; vibration distribution; impact noise; damping; elastomers; finite element analysis; experimental modal analysis; FRF; trästomme; träkonstruktion; träbyggnad; flervåningshus; EMA; FEM; flanktransmission; koppling; knutpunkt; vibrationsspridning; stomljud; stegljud; dämpning; elastomerer; finit elementmetod; experimentell modalanalys; accelerationsmätning; frekvensresponsfunktion; modalanalys;

    Abstract : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. READ MORE

  7. 5. Learning English in a Multi-User Virtual Environment : Exploring Factors Affecting Participation

    Author : Airong Wang; Mats Deutschmann; Mercedes Rico Garcia; Mittuniversitetet; []
    Keywords : HUMANIORA; HUMANITIES; Activity theory; Conversational Analysis; Discourse analysis; Ecology of language learning; Model of factors affecting participation; Multi-User Virtual Environment; Participation; Second Life; The sociocultural perspective on learning; Technology adoption;

    Abstract : Online language learning and teaching is a field that has received a significant amount of research attention. What factors could affect student participation in simpler online learning environments has been investigated by researchers, but there has been limited study of factors affecting participation in complex Multi-User Virtual Environments.
