  3. 2. Structural assessment procedures for existing concrete bridges : Experiences from failure tests of the Kiruna Bridge

    Författare :Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anchorage; carbon fibre reinforced polymers; concrete; existing bridges; finite element analysis; flexure; full-scale test; load-carrying capacity; residual prestress force; punching; safety verification; shear; structural assessment; structural behaviour; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Assessing existing bridges is an important task in the sustainable management ofinfrastructure. In practice, structural bridge assessments are usually conducted usingtraditional and standardised methods, despite knowledge that these methods oftenprovide conservative estimates. LÄS MER

  4. 3. Simultaneous Topology and Material Optimization of Composite Structures under Uncertainty

    Författare :Dženan Hozić; Carl-Johan Thore; François-Xavier Irisarri; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Optimization; Composite Structures; Topology Optimization; Multi-material Optimization; Material Uncertainty; Robust Optimization; Composite Structure Optimization; Design Optimization; Composite Material;

    Sammanfattning : Composite materials are known to have superior stiffness and strength properties per unit weight compared to metallic materials. These properties and the ability to tailor the mechanical properties of composites is the main motivation for choosing composite materials for structural components. LÄS MER

  5. 4. Real-time Locating Systems for indoor applications : the methodological customization approach

    Författare :Bartosz Jachimczyk; Wlodek Kulesza; Alfonso Bahillo Martínez; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accuracy and Precision; Angle of Arrival; Fingerprinting Method; Indoor Localization; Indoor Positioning System; Multi-Sensor System; Neural Network; Radio Frequency Identification - RFID; Real Time Locating System; Received Signal Strength; RFID Network Planning; Scene Analysis; Sensors Arrangement; System Customization; Uncertainty; Uncertainty Map; User Driven Design;

    Sammanfattning : Emerging wireless technologies increase the potential and effectiveness of wireless Real-time Locating Systems (RTLSs), which precisely localize the position, and identify things and people in real time. Among many applications, RTLSs are widely used in the industrial sector for indoor logistics and safety applications. LÄS MER

  7. 5. Vulnerable daughters in times of change: Emerging contexts of discrimination in Himachal Pradesh, India

    Författare :Mattias Larsen; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; daughter discrimination; sex-selective abortions; gender; development; intergenerational contract; dowry; context; structural change; uncertainty;

    Sammanfattning : This dissertation deals with the widespread problem in India of using sex selective abortions to discriminate against daughters. Girls are aborted on a massive scale simply because they are girls. A point of departure is the fact that the problem has become prevalent at a time of considerable social and economic change. LÄS MER
