  1. 1. Speed characteristics of urban streets based on driver behaviour studies and simulation

    Författare :Karin F. M. Aronsson; Karl-Lennart Bång; Bengt Holmberg; KTH; []
    Nyckelord :Speed; Characteristics; Urban area; Road network; Street; Traffic; Driver; Side-friction element; Driving simulator; Simulation; Measurement; Behaviour; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The objective of the study was to gain in-depth knowledge of speed relationships for urban streets. The speed characteristics were examined using a number of methods for data collection. LÄS MER

  3. 2. Vägen till jobbet : Om kvinnors och mäns arbetsresor i förändring

    Författare :Ana Gil Sola; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Change; commuting; distance; gender; men; regional enlargement; speed; time; means of transportation; women; work-related mobility;

    Sammanfattning : Equal access to work is a central dimension of welfare and the starting point for this study. From a geographical point of view this highlights issues of gender-related differences in distance and travel between home and work. Also, in Swedish regional planning and policy, the key concept of regional enlargement (i.e. LÄS MER

  4. 3. Modeling Music : Studies of Music Transcription, Music Perception and Music Production

    Författare :Anders Elowsson; Anders Friberg; Pawel Herman; Anders Askenfelt; Gerhard Widmer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Music Information Retrieval; MIR; Music; Music Transcription; Music Perception; Music Production; Tempo Estimation; Beat Tracking; Polyphonic Pitch Tracking; Polyphonic Transcription; Music Speed; Music Dynamics; Long-time average spectrum; LTAS; Algorithmic Composition; Deep Layered Learning; Convolutional Neural Networks; Rhythm Tracking; Ensemble Learning; Perceptual Features; Representation Learning;

    Sammanfattning : This dissertation presents ten studies focusing on three important subfields of music information retrieval (MIR): music transcription (Part A), music perception (Part B), and music production (Part C).In Part A, systems capable of transcribing rhythm and polyphonic pitch are described.

  5. 4. Survey models for a vehicle speed survey

    Författare :Annica Isaksson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; frame error; missing data; error model; optimum allocation; total error; MATHEMATICS; MATEMATIK;

    Sammanfattning : The impact of some errors, associated with a road traffic survey, is examined. The survey aims at evaluating efforts to reduce the speeds on Swedish roads. It covers both state and urban roads, but we consider only the latter. From these roads, observational sites are selected by a three-stage sampling procedure. LÄS MER

  7. 5. Fuel-Efficient Truck Platooning using Speed Profile Optimization

    Författare :Sina Torabi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis is concerned with fuel-efficient driving strategies for heavy-dutyvehicles driving on highways with varying topography. A method for reducingthe fuel consumption of single trucks and platoons consisting of several trucksis described and evaluated both in simulation and in real trucks. LÄS MER
