   Författare :Samuel Lukas Lienemann; Klas Tybrandt; Magnus Berggren; Diego Ghezzi; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stretchable electronics; Nanowires; Peripheral nerve interfaces; Cuff electrodes;

   Sammanfattning : Within our body, there is a large network of nerves that facilitates communication between the brain and the body’s organs. This network is called our peripheral nervous system, consisting of soft and stretchable nerve bundles that gradually increase in their functional specificity as they split and branch out the closer they get to their target organ.

3. 2. Sensitivity Analysis and Material Parameter Estimation using Electromagnetic Modelling

   Författare :Therese Sjödén; Sven Nordebo; Börje Nilsson; Margaret Cheney; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensitivity analysis; material parameter; Fisher information; Cramér-Rao bound; electromagnetic modelling; grain angle; wood; electrical impedance tomography; inverse problems; känslighetsanalys; estimering; materialparameter; Fisher- information; Cramér-Rao-gränsen; elektromagnetisk modellering; fibervinkel; trä; elektrisk impedanstomografi; inversa problem; Waves; Signals and Systems; Vågor; signaler och system;

   Sammanfattning : Estimating parameters is the problem of finding their values from measurements and modelling. Parameters describe properties of a system; material, for instance, are defined by mechanical, electrical, and chemical parameters. Fisher information is an information measure, giving information about how changes in the parameter effect the estimation. LÄS MER

4. 3. Characterization of Conduction and Polarization Properties of HVDC Cable XLPE Insulation Materials

   Författare :Hossein Ghorbani; Hans Edin; Erling Ildstad; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC insulation; power cable insulation; cross-linked polyethylene insulation; conductivity; dielectric losses; space charge; HVDC isolation; kraftkabel isolation; tvärbunden polyeten isolationsmaterial; elektrisk ledningsförmåga; dielektriska förluster; rymdladdning; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Since its first introduction in 1998, extruded direct current (DC) cable technology has been growing rapidly leading to many cable system installations with operation voltages up to 320 kV. Cable manufacturers invest heavily on technology development in this field and today extruded DC cable systems for operation voltages as high as 525 kV are commercially available. LÄS MER
