  1. 1. Risk Management in Tunneling Projects : Estimation and Planning

    Författare :Mohammad Mohammadi; Johan Spross; Fredrik Johansson; Stefan Larsson; Anna Kadefors; Amund Bruland; KTH; []
    Nyckelord :Cost overrun; Transport infrastructure projects; Time and cost estimation; Probabilistic approaches; Tunneling; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Cost overruns and schedule delays are frequently observed occurrences in the construction of transport infrastructure projects. Such phenomena lead to the mismanagement of significant amounts of both public and private resources. LÄS MER

  2. 2. Estimation of Speaker Age : Effects of Speech Properties and Speech Material

    Författare :Sara Skoog Waller; Mårten Eriksson; Billy Jansson; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Age estimation; Voice perception; Speech properties; Speech rate; Vocal disguise; Age disguise; Accuracy; Confidence; Spontaneous speech;

    Sammanfattning : The aim of this thesis was to investigate factors related to accuracy in estimation of speaker age and the role of certain speech properties in perception and manipulation of speaker age, as well as their interaction with the speech material that the age estimates were based on. This thesis consists of three studies. LÄS MER

  3. 3. Estimation and detection of transmission line characteristics in the copper access network

    Författare :Fredrik Lindqvist; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital subscriber line; DSL; line qualification; twisted-pair line; copper access network; cable modeling; crosstalk channel estimation; estimation; detection;

    Sammanfattning : The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. LÄS MER

    Sammanfattning : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. LÄS MER

  5. 5. Curvature Estimation and Description

    Författare :Håkan Bårman; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This paper presents a new method for detection and estimation of curvature. The algorithm is implemented in the hierarchical feature pyramid proposed in the GOP concept. Curvature is handled at the second level of the pyramid with a vector field description of the orientation of the image as input. LÄS MER
