  1. 1. Lithium-intercalated Carbon Fibres : Towards the Realisation of Multifunctional Composite Energy Storage Materials

    Författare :Eric Jacques; Dan Zenkert; Göran Lindbergh; Milo Shaffer; KTH; []
    Nyckelord :Flyg- och rymdteknik; Aerospace Engineering;

    Sammanfattning : Lightweight design is a major improvement path for sustainable transport asit contributes to lower vehicles energy consumption and gas emissions. Anovel solution to weight savings is to store energy directly in the mechanicalstructure of the vehicle with a multifunctional material, called structural battery,which could simultaneously bear mechanical loads and store electricalenergy.

  3. 2. First-Order Algorithms for Communication Efficient Distributed Learning

    Författare :Sarit Khirirat; Mikael Johansson; Martin Jaggi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Communication efficient learning; Optimization algorithms; Quantization; Error compensation; First-order algorithms; Stochastic gradient descent; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics; Optimeringslära och systemteori; Optimization and Systems Theory; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Technological developments in devices and storages have made large volumes of data collections more accessible than ever. This transformation leads to optimization problems with massive data in both volume and dimension. LÄS MER

  4. 3. Neurogenesis from Neural Stem Cells, Ependymal Cells and Fibroblasts

    Författare :Karthikeyan Devaraju; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adult neurogenesis; stroke; neural stem cells; Lnk; ependymal cells; FoxJ1; cortical reprogramming;

    Sammanfattning : Stroke is a major cause of death and disability around the world. Stroke leads to loss of neurons and also other cells in the brain due to lack of blood supply. Currently no therapies are available to treat stroke-related disability. It has been shown that stroke leads to increased neurogenesis, birth of new neurons, within the brain. LÄS MER

  5. 4. The influence of alcohol on bone metabolism and fracture healing

    Författare :Fredrik Nyquist; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kirurgi; traumatology; orthopaedics; Surgery; fracture prediction.; fracture healing; bone mineral density; Alcohol; post-traumatic osteopenia; fracture; ortopedi; traumatologi; Skeleton; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi;

    Sammanfattning : The influence of alcohol on bone metabolism, fracture and fracture healing was evaluated in men and male rats by measurements of bone mineral density (BMD), biochemical markers and biomechanical testings. Retrospectively, 199 male patients hospitalized for tibia shaft fractures were studied. Forty-nine were judged as problem drinkers. LÄS MER

  7. 5. Design of Transition-Metal Nitride Thin Films for Thermoelectrics

    Författare :Sit Kerdsongpanya; Per Eklund; Björn Alling; Gunilla Wingqvist; Lars Hultman; Daniel Gall; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Thermoelectric devices are one of the promising energy harvesting technologies, because of their ability to convert heat (temperature gradient) to electricity by the Seebeck effect. Furthermore, thermoelectric devices can be used for cooling or heating by the inverse effect (Peltier effect). LÄS MER
