  2. 1. Perpetual product development : a study of small technology-driven firms

    Author : Jan Bodin; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Perpetual product development; technology; aircraft industry; small firms; inventor; key actors; resources;

    Abstract : This dissertation focuses the attention toward inventors and key actors involved in product development projects. The study focuses on how a new product development process is carried out operationally and strategically in small, technology-driven firms. READ MORE

  4. 2. X-ray Phase Contrast Tomography : Setup and Scintillator Development

    Author : Hanna Dierks; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-rays; x-ray imaging; x-ray microscopy; X-ray detectors; perovskites; laboratory setups; phase contrast; μCT; scintillator; Phase contrast PC ; Tomography x-ray computed ;

    Abstract : X-ray microscopy and micro-tomography (μCT) are valuable non-destructive examination methods in many disciplines such as bio-medical research, archaeometry, material science and paleontology. Besides being implemented at synchrotrons radiation sources, laboratory setups using an X-ray tube and high-resolution scintillation detector routinely provide information on the micrometre scale.

  5. 3. Simulation of Phase Transformations and coarsening : Computational tools for alloy development

    Author : Johan Jeppsson; John Ågren; Gerhard Inden; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Abstract : The final properties of an alloy are highly interlaced with its microstructure. It is therefore essential to control the evolution of the microstructure of the material during the fabrication process. Nowadays, materials design involves an increasing part of computational design to complement the traditional experimental trial and error approach. READ MORE

  6. 4. Frequency Noise in Coherent Optical Systems: Impact and Mitigation Methods

    Author : Aditya Kakkar; Richard Schatz; Sergei Popov; Gunnar Jacobsen; Xiaodan Pang; Oskars Ozolins; Magnus Karlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Equalization enhanced phase noise; frequency noise; coherent optical communications; carrier phase recovery; carrier phase estimation; circular quadrature amplitude modulation; EEPN; CmQAM; blind phase search; phase noise;

    Abstract : The increase in capacity demand along with the advancement in digital signal processing (DSP) have recently revived the interest in coherent optical communications and led to its commercialization. However, design and development of robust DSP algorithms for example for carrier phase recovery (CPR) becomes complex as we opt for high order modulation formats such as 16QAM and beyond. READ MORE

  7. 5. Development of functional asymmetries in young infants : A sensory-motor approach

    Author : Erik Domellöf; Louise Rönnqvist; Jacqueline Fagard; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Laterality; development; handedness; human infant; stepping response; placing response; head turning; arm movement; reaching; kinematic parameters; intralimb coordination; Psychology; Psykologi;

    Abstract : Human functional laterality, typically involving a right-sided preference in most sensory-motor activities, is still a poorly understood issue. This is perhaps particularly true in terms of what underlying mechanisms that may govern lateral biases, as well as the developmental origins and course of events. READ MORE
