  2. 1. Congenital clubfoot : Aspects on epidemiology, residual deformity and patient reported outcome

    Author : Henrik M Wallander; Göran Hansson; Sune Larsson; Michael Benson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Congenital clubfoot; incidence; ultrasonography; forefoot adduction; navicular position; spurious correction; Ilizarov External Fixator; subjective outcome; stiffness; patient reported outcome; norm group; gender difference; Orthopaedics; Ortopedi; Orthopaedics; ortopedi;

    Abstract : The overall aim of this thesis on congenital clubfoot was to estimate the incidence with a national perspective, analyse residual deformities and their management, and evaluate patient reported long-term quality of life and foot function. Paper I was a prospective, nationwide sampling of 280 children with congenital clubfoot during 1995-96. READ MORE

  4. 2. Modeling and post-correction of pipeline analog-digital converters

    Author : Samer Medawar; Peter Händel; Martin Gustafsson; KTH; []
    Keywords : ;

    Abstract : Integral nonlinearity (INL) for pipelined analog-digital converters (ADCs) operating at radio frequency is measured and characterized. A parametric model for the INL of pipelined ADCs is proposed and the corresponding least-squares problem is formulated and solved. READ MORE

  5. 3. Representation and diurnal variation of upper tropospheric humidity in observations and models

    Author : Ajil Kottayil; Byung-Ju Sohn; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rymdteknik; Space Technology;

    Abstract : The role of water vapour is manifold in its climate regulation of the Earth system. Most important of all despite its low concentration, is the role it plays in the upper troposphere. READ MORE

  6. 4. Van der Waals Interactions in Density Functional Theory

    Author : Erika Hult; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; van der Waals interaction; exchange-correlation energy; adhesion; intermolecular forces; physisorption; density functional theory;

    Abstract : Density functional theory is a very important method for calculating ground-state properties for atoms, molecules and solids. Albeit exact in principle, its implementation requires an approximation for the so-called exchange-correlation energy. READ MORE

  7. 5. Modeling and Implementation of Current-Steering Digital-to-Analog Converters

    Author : Ola Andersson; Mark Vesterbacka; Saska Lindfors; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data converter; analog-to-digital converters ADCs ; digital-to-analog converters DACs ; transistor; Electrical engineering; Elektroteknik;

    Abstract : Data converters, i.e., analog-to-digital converters (ADCs) and digital-to-analog converters (DACs), are interface circuits between the analog and digital domains. They are used in, e. READ MORE
