  2. 1. Development of Nanostructured Tungsten Based Composites for Energy Applications

    Author : Mazher Ahmed Yar; Mamoun Muhammed; Per-Olov Käll; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tungsten; Nano-tungsten; ODS tungsten; W-La2O3; W-Y2O3; SPS; Plasma-facing materials; Armour material; fusion material;

    Abstract : Tungsten (W) based materials can be used in fusion reactors due to several advantages. Different fabrication routes can be applied to develop tungsten materials with intended microstructure and properties for specific application including nanostructured grades. READ MORE

  4. 2. Improved Bridge Evaluation

    Author : Hendrik Schlune; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model updating; structural identification; Bridge evaluation; concrete structures; finite element analysis; finite element method; load cases;

    Abstract : Accurate structural models are required for optimal management of existing bridges and economical new ones. However, unavoidable modelling uncertainties and difficulty in modelling the non-linear response of concrete bridges can lead to structural models which do not fulfil this requirement. READ MORE

    Author : Kristina Säfsten; Mats Johansson; Linköpings universitet; []
    Keywords : ;

    Abstract : Evaluation is considered as one of several activities necessary to master in the competitive environment that manufacturing companies experience today. The specific situation addressed in this dissertation is evaluation during development of assembly systems. READ MORE

  6. 4. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation

    Author : Eboh Francis Chinweuba; Simon Harvey; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

    Abstract : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. READ MORE

  7. 5. A flexible resonance sensor system for detection of cancer tissue : evaluation on silicon

    Author : Anders P. Åstrand; Britt Andersson; Ville Jalkanen; Olof A. Lindahl; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The most common form of cancer among men in Europe and the US is prostate cancer. When a radical prostatectomy has been found necessary, it is of interest to examine the prostate, as tumour tissue on the capsule might indicate that the cancer has metastased. This is commonly done by a microscope-based morphometric investigation. READ MORE
