  1. 1. LCC Applications for Bridges and Integration with BMS

    Författare :Mohammed Safi; Håkan Sundquist; Raid Karoumi; Milan Veljkovic; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge; Management; life-Cycle Costing; LCC; Bridge Management System; SRA - Transport; SRA - Transport; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Sammanfattning : Bridges are vital links in many transport networks and represent a big capital investment for both governments and taxpayers. They have to be managed in a way that ensures society's needs are optimally met. In many countries, bridges are mainly managed using bridge management systems (BMSs). LÄS MER

  2. 2. Steel fibrous cement based composites: material and mechanical properties : behavior in the anchorage zones of prestressed bridges

    Författare :Lutfi Ay; KTH; []
    Nyckelord :process improvement of bridges; prestressed concrete; high performance concrete;

    Sammanfattning : This PhD thesis is divided into two parts. Part one dealswith the development of the material and the mechanicalproperties of Steel Fibrous Cement Based Composites (SFCBC) forimproving bridge design and construction. It familiarizes thehydration mechanisms of the high performance concrete with thehelp of Powers´ and Jensen´s models. LÄS MER

  3. 3. Lessons Learned in Structural Health Monitoring of Bridges Using Advanced Sensor Technology

    Författare :Merit Enckell; Johan Silfwerbrand; Konrad Bergmeister; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; Structural Health Monitoring System; bridges; sensor technology; emerging technology; fibre optics; fibre optic sensors concrete; creep; shrinkage; steel; distributed sensors; crack detection; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Sammanfattning : Structural Health Monitoring (SHM) with emerging technologies like e.g. fibre optic sensors, lasers, radars, acoustic emission and Micro Electro Mechanical Systems (MEMS) made an entrance into the civil engineering field in last decades. Expansion of new technologies together with development in data communication benefited for rapid development. LÄS MER

  4. 4. Three Dimensional Hydro-Morphological Modeling of Tigris River

    Författare :Ammar Ali; Robert William Duck; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The River Tigris is a major river in Iraq. It divides Baghdad, the capital of Iraq, in two parts. The reach of the river within Baghdad is about 60 km long. The climate change within the region and the construction of hydraulic structures upstream of Baghdad has reduced the water discharge of the river by 44%. LÄS MER

  5. 5. Sensory qualities and culinary utility of produce : a path towards sustainable gastronomy

    Författare :Magnus Westling; Åsa Öström; Stefan Wennström; Michael Bom Frøst; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Culinary action; culinary arts; cultivated diversity; food design; food science; gastronomic potential; gastronomy; gray peas; meal science; sensory science;

    Sammanfattning : The underlying assumption throughout this thesis is that the continuity of a cultivated diversity can be strengthened by investigating its sensory qualities and specifying particular culinary utilities of landraces and cultivars. How can a foodstuff’s sensory qualities and culinary utility be explored, tested, and refined together with the food industry and the public meal? This thesis aims to create a path toward sustainable gastronomy with greater sensory variation that originate from a cultivated diversity. LÄS MER
