  1. 1. Spectral Image Processing with Applications in Biotechnology and Pathology

    Author : Milan Gavrilovic; Carolina Wählby; Ewert Bengtsson; Ingrid Carlbom; Robert Murphy; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; color theory; light microscopy; spectral imaging; image analysis; digital image processing; mathematical modeling; estimation; noise models; spectral decomposition; color decomposition; colocalization; cross-talk; autofluorescence; tissue separation; prostate cancer; biomedical applications; molecular biotechnology; histopathology; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Color theory was first formalized in the seventeenth century by Isaac Newton just a couple of decades after the first microscope was built. But it was not until the twentieth century that technological advances led to the integration of color theory, optical spectroscopy and light microscopy through spectral image processing. READ MORE

  2. 2. Synaptic uncoupling in the mouse cochlea induced by noise or cisplatin and its clinical relevance

    Author : Evangelia Tserga; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : The cochlea has an autonomous circadian clock that controls auditory function and increases vulnerability to noise trauma during the active phase. The mechanisms regulating the circadian control of the auditory system are poorly understood. READ MORE

  3. 3. Signal Processing Tools for Electron Microscopy

    Author : Jakob Spiegelberg; Jan Rusz; Kristiaan Pelckmans; Peter M. Oppeneer; Johan Verbeeck; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES;

    Abstract : The detection of weak signals in noisy data is a problem which occurs across various disciplines. Here, the signal of interest is the spectral signature of the electron magnetic chiral dichroism (EMCD) effect. READ MORE

  4. 4. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals

    Author : Sara Abbaspour; Maria Lindén; Urban Wiklund; Mälardalens högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. READ MORE

  5. 5. Management of urban woodlands - effects on bird communities and recreational values

    Author : Erik Heyman; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Forest management; Urban woodlands; Birds; Recreation; Clearance; Understory;

    Abstract : The ongoing urbanisation increases the pressure on urban nature. Urban woodlands are receiving growing attention as they provide valuable ecosystem services to urban citizens, mainly by providing areas for recreation but also through improving air quality and reducing noise. READ MORE
