  2. 16. Membrane Filtration of Lignocellulosic Materials: In situ Monitoring of Membrane Fouling Using Fluid Dynamic Gauging

    Author : Kenneth Gacutno Arandia; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood components; Membrane fouling; Fluid dynamic gauging; Cross-flow filtration;

    Abstract : The transition of process industries from utilizing fossil-based resources to bio-based ones necessitates energy-efficient and selective operations. One practical operation that can be employed for processing streams containing lignocellulosic biomass, such as forest and agricultural residues, is membrane separation. READ MORE

  4. 17. Dynamic avalanche in Si and 4H-SiC power diodes

    Author : Martin Domeij; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Semiconductor power modules for the control of high currentsand high voltages have important applications in motor drives,traction and power transmission. Dynamic avalanche is of atechnological interest since it may limit the safe operatingarea for bipolar switching devices and for power diodes, whichare important integral parts of a power module.

  5. 18. On the dynamic ST-segment during acute myocardial infarction

    Author : Per Johanson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute myocardial infarction; ST-monitoring; prognosis; angiography;

    Abstract : Acute myocardial infarction is the single most common cause of death for both men and women in Sweden. Great efforts have over the years successfully been made to improve immediate treatment and care, and thereby prognosis. However, inadequacies in use of new knowledge and technology have been reported in this field. READ MORE

  6. 19. Dizziness, balance and rehabilitation in vestibular disorders

    Author : Lena Kollén; Claes Möller; Margareta Möller; Monika Fagevik Olsén; Mikael Karlberg; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; benign paroxysmal positional vertigo; static balance; dynamic balance; unilateral vestibular loss; dizziness; walking; vestibular rehabilitation; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN; Caring sciences; Vårdvetenskap; Vårdvetenskap; Nursing Science;

    Abstract : Dizziness and balance problems are common symptoms at all ages. The aims were; to evaluate rehabilitation, static, dynamic balance and recovery in acute unilateral vestibular loss (AUVL), to evaluate the treatment of benign paroxysmal positional vertigo (BPPV) with assessment of static and dynamic balance and to evaluate the prevalence of dizziness and BPPV in a population of 75-year-olds.

  7. 20. Structure and Motion Estimation in Rigid Body Perspective Dynamic Systems

    Author : Fredrik Nyberg; Matematikcentrum; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Abstract This thesis concerns different aspects of recursive estimation of structure and motion in dynamic rigid body perspective systems, where the three-dimensional position of observed object feature points are expressed as states in a system of deterministic or stochastic differential equations describing the object motion, combined with a set of output equations in the form of two-dimensional perspective measurements obtained using a single camera. Firstly, a number of novel hybrid matching constraints are derived for the recovery of motion parameters in a rigid body perspective system where the measurements can be considered as arriving at closely spaced time instants.
