  2. 16. On the establishment of effective condition-based maintenance for oil-filled electrical transformers to reduce failures due to copper corrosion problems and its role toward sustainable energy

    Author : Ramsey Jadim; Mirka Kans; Lina Bertling Tjernberg; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CBM; CM procedures; corrosion problems; transformer oil analysis; corrosive sulfur; transformer failures; sustainable maintenance; sustainable energy supply; Maskinteknik; Mechanical Engineering;

    Abstract : Oil-filled electrical transformers are critical equipment for modern societies where a sustainable energy supply is required. Recently, many severe fire and explosion accidents of transformers have been reported due to copper corrosion problems in the form of copper sulfide deposits on the windings. READ MORE

  4. 17. Polyolefin Flame Retardant Cable Materials - Effect of Additives and Copolymer Structure

    Author : Linus Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calcium Carbonate; Flame Retardant; Silicone Elastomer; Melt Viscosity; Ethylene-Acrylate Copolymer;

    Abstract : Fire safety of cables is becoming increasingly important as the use of electrical equipment steadily increases. Due to their excellent dielectric properties, polyolefin materials are widely used as insulating materials for cables. However, polyolefins are inherently flammable and need to be protected to meet the requirements on flame retardancy. READ MORE

  5. 18. Use of energy-signature method to estimate energy performance in single-family buildings

    Author : Gustav Nordström; Jutta Schade; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : The renewal of the existing housing stock is a slow progress and theexisting is quite old. The existing housing stock represents a largeamount of the bought energy need for heating and a simple method forquickly determining the energy performance is needed.There are many different methods for estimating the energyperformance of buildings.

  6. 19. Conductance-based principles of neuronal firing and excitability

    Author : Hugo Zeberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The brain is an electrical organ whose activity is determined by the flow of ions across cell membranes. As such, the conductances that control the ion flux is a key to our understanding of the nervous system. Neurons process information by their ability to rapidly depolarize and fire action potentials.

  7. 20. Information processing in the Striatum : a computational study

    Author : Johannes Hjorth; Jeanette Hellgren Kotaleski; Anders Lansner; Kim Blackwell; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; striatum; fast spiking interneuron; gap junctions; synchronisation; up-state detection; CaMKII; mathematical modelling; Neuroscience; Neurovetenskap;

    Abstract : The basal ganglia form an important structure centrally placed in the brain. They receive input from motor, associative and limbic areas, and produce output mainly to the thalamus and the brain stem. The basal ganglia have been implied in cognitive and motor functions. READ MORE
