  2. 11. Entanglement detection schemes and coherent manipulation of spin in quantum dots

    Author : Ognjen Malkoc; NanoLund: Centre for Nanoscience; []
    Keywords : Quantum dots; Entanglement; Current noise; Spin relaxation; Fysicumarkivet A:2016:Malkoc;

    Abstract : The work contained in this thesis deals with two closely related topics. Papers I-III deal with charge transport statistics in nanoscale devices to investigate the presence of entanglement in the constituent electrons. We identify the contributions of entangled electron pairs to the current cross-correlations as a signature of entanglement. READ MORE

  4. 12. Performance analysis of a low-speed high-torque hydrostatic transmission unit

    Author : Håkan Olsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : This thesis concerns a study of the performance of an industrial low-speed high-torque hydrostatic drive system. This type of hydrostatic transmission is commonly used in continuous operation in a wide range of heavy-duty drive applications. In many applications the transmissions have to compete with e.g. READ MORE

  5. 13. Carbon Nanotube Transistors: Nanotube Growth, Contact Properties and Novel Devices

    Author : Johannes Svensson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon nanotube; chemical vapour deposition; Field effect transistor; Marangoni convection; Schottky barrier;

    Abstract : Carbon nanotubes (CNTs) are envisioned to be used as the basic building blocks in future electronics due to their excellent electronic properties such as high mobility, compatibility with high-k dielectrics and small diameters resulting in advantageous electrostatics. This thesis is divided into three separate topics related to increasing the fabrication yield and performance of CNT field effect transistors (CNTFETs). READ MORE

  6. 14. Computational Models in Deep Brain Stimulation : Patient‐Specific Simulations, Tractography, and Group Analysis

    Author : Teresa Nordin; Karin Wårdell; Simone Hemm-Ode; Johannes D. Johansson; Harith Akram; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anisotropy; Deep brain stimulation DBS ; Finite element method FEM ; Patient‐specific simulation; Probabilistic stimulation maps PSM ; Tractography;

    Abstract : Deep brain stimulation (DBS) is an established method for symptom relief in movement disorders like Parkinson’s disease, essential tremor (ET), and dystonia. The therapy is based on implanting an electrode with four contacts in the deep brain structures where it provides electrical stimulation, mainly impacting the nerve tracts. READ MORE

  7. 15. Energy Services in Sweden - Customer Relations towards Increased Sustainability

    Author : Kerstin Sernhed; Energihushållning; []
    Keywords : demand-side management; district heating; electricity; Customer relations; district-heating marketing strategies; load management; feedback;

    Abstract : Energy use and supply are evident issues to consider for a sustainable development, where the economic, social and environmental aspects are all important. In large grid-bound systems, the supply of energy is usually a rather invisible activity and the contacts between household custo-mers and utilities are sometimes only repre-sented through the energy bill.
