  2. 1. Structural aspecs on compounds in the CsI-(Cd/Hg)I2 system

    Author : Rune Sjövall; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tetrahedral distorsion; thermal decomposition; Biltz concept; structural relationships; hydrate; iodine; mercury; caesium; cadmium; coordination number modelling; Inorganic chemistry; Oorganisk kemi;

    Abstract : Structural investigations of compounds in the CsI-(Cd/Hg)I2 system have been performed by means of X-ray diffraction, thermogravimetric and calorimetric techniques. Crystals of the compounds studied were synthesized from aqueous solutions of CsI and CdI2/HgI2 by the slow evaporation of water. READ MORE

  4. 2. Structural Identification of Civil Engineering Structures

    Author : Tarek Edrees; Andreas Andersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The assumptions encountered during the analysis and design of civil engineering structures lead to a difference in the structural behavior between calculations based models and real structures. Moreover, the recent approach in civil engineering nowadays is to rely on the performance-based design approaches, which give more importance for durability, serviceability limit states, and maintenance.

  5. 3. Hierarchical Structuring of Mg2Si1-xSnx Alloys for Lower Thermal Conductivity and Thermal Conductivity as Probe for Structural Characterization

    Author : Andrey Sizov; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; structural probing; Rietveld refinement; hot disc; spinodal decomposition; magnesium silicide-stannide; Microstructuring; phase separation; X-ray diffraction; thermal conductivity; thermoelectrics;

    Abstract : The thermoelectric effect was discovered nearly 200 years ago, but it started to be utilized for waste heat recovery fairly recently. From the economical point of view, such application requires a cheap and efficient material, which is able to convert heat energy into electricity. READ MORE

  6. 4. Structural investigations of some ternary metal hydrides

    Author : Ewa Rönnebro; Gary Sandrock; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

    Abstract : This work was undertaken with the intention of describing the metal atom environment of hydrogen in a selection of ternary metal hydrides that could be of interest as hydrogen sorption materials. Mainly X-ray and neutron diffraction techniques were used for the purpose. READ MORE

  7. 5. Structural Control and Identification of Civil Engineering Structures

    Author : Tarek Edrees; Francesc Pozo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion; Structural Engineering; Konstruktionsteknik;

    Abstract : In general, the main purpose of a structural control system is to apply powerful control techniques that improve the behaviour of civil structures under various kinds of dynamic loading. The first part of this thesis presents novel applications of posicast and input shaping control schemes that have never previously been applied in the field of structural control. READ MORE
