  1. 1. Foam Core Materials for High Performance Sandwich Constructions: Preparation, Testing and Properties

    Author : Mikael Danielsson; Chalmers University of Technology; []
    Keywords : IPN; core material; low temperature; polyurea; polyethersulfone; gradient structure; foam; PVC; sandwich; waste; fire; smoke; toxicity; mechanical properties; Inter Penetrating Polymer Network; dynamic properties; high temperature;

    Abstract : The basic task for foams used as core materials in sandwich constructions is to separate the skin layers in order to enhance stiffness with little contribution to the total weight. However, modern design in sandwich technology require that core materials contribute to the perfor-mance with specific mechanical and physical properties. READ MORE

  2. 2. High Temperature Corrosion in Fluidised Bed Environment

    Author : Anna Nafari; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFB; coatings; Ni and iron based alloys; HCl; SO2; loop seal; High temperature corrosion; erosion corrosion test rig; surface characterization and temperature gradient;

    Abstract : Successful material selection for power plants is the result of understanding the environment in each boiler. The boiler environment is affected by fuel chemistry, co-firing, process control and deposits as well as boiler type, design, size and load. READ MORE

  3. 3. Thermal Issues in Testing of Advanced Systems on Chip

    Author : Nima Aghaee Ghaleshahi; Zebo Peng; Petru Eles; Jaan Raik; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; SoC test; test scheduling; Adaptive test; Temperature awareness; Process variation; Thermal simulation; 3D stacked IC 3DSIC test; Burn-in; Temperature gradients; Temperature Cycling Test; Test Ordering;

    Abstract : Many cutting-edge computer and electronic products are powered by advanced Systems-on-Chip (SoC). Advanced SoCs encompass superb performance together with large number of functions. This is achieved by efficient integration of huge number of transistors. READ MORE

  4. 4. Temperature Gradient Instabilities and Transport in Toroidal Plasmas

    Author : Mats Fröjdh; Chalmers University of Technology; []
    Keywords : ;

    Abstract : This thesis focuses on temperature gradient driven modes and their implications for heat and particle transport in toroidal plasmas. Some of the consequences of including an ion impurity species in a model for low frequency electrostatic modes and fluctuation driven transport are discussed. READ MORE

  5. 5. Atmospheric transport of persistent organic pollutants to aquatic ecosystems

    Author : Cecilia Agrell; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecology; Temperature; Latitude; Deposition; PCB; Baltic Sea; Ekologi;

    Abstract : The load of persistent organic pollutants (POPs) is considered high in the Baltic ecosystem. The Baltic Sea spans over 12 latitudes and the regional differences in climate affect the behavior of POPs. READ MORE
