  1. 21. The Physical Axon : Modeling, Simulation and Electrode Evaluation

    Författare :Malcolm Latorre; Karin Wårdell; Göran Salerud; Ulrich Hofmann; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Electrodes are used in medicine for detection of biological signals and for stimulating tissue, e.g. in deep brain stimulation (DBS). For both applications, an understanding of the functioning of the electrode, and its interface and interaction with the target tissue involved is necessary. LÄS MER

  3. 22. Multi-level Interactions between Fisheries and Trade : Modeling intertwined social-ecological systems

    Författare :Laura G. Elsler; Schlüter Maja; Florian Diekert; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; multi-level interactions; social-ecological model; trade relationships; complexity; inequality in fisheries; fisheries sustainability; seafood trade; international markets; fisheries collapse; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Sustainable and equitable fisheries are central for addressing the challenges of the UN Sustainable Development Goal 14: Life Below Water. International trade, once presented by Walrasian economists as a panacea for fisheries development, has not markedly decreased poverty and has been related to the overexploitation of marine species.

  4. 23. Signal Modeling and Data Reduction for Wireless Brain-Machine Interfaces

    Författare :Palmi Thor Thorbergsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Extracellular neural recordings; wireless brain-machine interfaces; signal modeling; data reduction; compression;

    Sammanfattning : Brain-machine interfaces (BMIs) provide a uni- or bidirectional communication link between the central nervous system and the outside world. This link facilitates the studying of neuronal mechanisms underlying behavior as well as the treatment of neurological disease. LÄS MER

  5. 24. Fish Lenses : Anatomy and Optics

    Författare :Tomasz M Kozłowski; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plasticity; Development; Cellular structure; Lens fiber cells; Modeling; Laser Scanning; Schlieren photography; Fast Fourier Transform FFT ;

    Sammanfattning : I have investigated some of the biological regulatory mechanisms governing the development of crystalline lenses. I used fish as model animals because they possess optically interesting lenses, while the geometrical simplicity of fish lenses allows for studies that are difficult or impossible with the lenses of other animals.

  7. 25. WC grain growth during sintering of cemented carbides : Experiments and simulations

    Författare :Karin Mannesson; John Ågren; Annika Borgenstam; Håkan Engqvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cemented carbide; Grain growth; Abnormal grain growth; Image analysis; Modeling; 3-D grain size distribution; Inverse Saltykov; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Cemented carbides are composite materials consisting of a hard carbide and a ductile binder. They are powdermetallurgically manufactured, where liquid-phase sintering is one of the main steps. The most common cemented carbide consists of WC and Co and it is widely used for cutting tools.
