  2. 6. Lithium-ion battery models for performance and aging

    Author : Jing Ying Ko; Göran Lindbergh; Ulrike Krewer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion batteries; pseudo two-dimensional model; model extension; parametrization; aging; lifetime; Chemical Engineering; Kemiteknik;

    Abstract : The demand for lithium-ion batteries (LiBs) is increasing at an exponential rate, so is the need to understand their behaviors and properties.In this pursuit, models are useful tools for improving cell design,quality, control system, keeping track of performance, aging andlifetime.

  4. 7. Concrete pavements’ repair techniques and numerical assessment of dowel bar load transfer efficiency

    Author : Saima Yaqoob; Johan Silfwerbrand; Larissa Strömberg; Anne Beeldens; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete pavements; Rapid repair; Precast slabs; Dowel bar; Load transfer efficiency; Betongbyggnad; Concrete Structures;

    Abstract : Concrete pavements are a suitable alternative for high-traffic volume roads, concentrated loads and roads exposed to severe weather conditions. In Sweden, among other reasons, the scarcity of concrete pavements is attributed to the need for more national knowledge and expertise in the field. READ MORE

  5. 8. Fatigue assessment of riveted bridges

    Author : Tobias Larsson; Mohammad Al-Emrani; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The majority of the railways used today were built in the beginning of the 20th century. Most of the bridges constructed at that time are still in service. READ MORE

  6. 9. GALIELLALACTONE ANALOGUES – SYNTHESIS AND PROPERTIES

    Author : Ritha Gidlöf; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Galiellalactone; one-pot peptide coupling and intramolecular Michael addition; tandem palladium-catalyzed carbonylation intramolecular Diels-Alder; STAT3 inhibition;

    Abstract : Cancer cells use normal cell signalling pathways in a proliferative fashion in order to prolong their own survival. Inhibition of one of the major signal proteins, STAT3 (Signal Transducer and Activator of Transcription 3) has previously been shown to induce apoptosis. READ MORE

  7. 10. Identifying Parameters for Aging-Adaptive Battery Management

    Author : Moritz Streb; Göran Lindbergh; Matilda Klett; Kandler Smith; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion battery; Parameter estimation; Aging-adaptive usage; Electrochemical battery management; Litiumjonbatteri; Parameteruppskattning; Åldringsmedveten användning; Elektrokemisk batterikontroll; Chemical Engineering; Kemiteknik;

    Abstract : The modern transportation system is largely based on fossil fuels. To reduce this reliance on oil and gas and thereby drastically reduce emissions, a transition to renewable power sources is necessary. Lithium-ion batteries are the most established candidate for electromobility applications, with suitable energy and power densities. READ MORE
