  2. 16. Enhancement of Salient Image Regions for Visual Object Detection

    Author : Keren Fu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geodesic distance; graph spectral decomposition; video processing; visual attention; color contrast and distribution; propagation; salient region; figure-ground segmentation;

    Abstract : Salient object/region detection aims at finding interesting regions in images and videos, since such regions contain important information and easily attract human attention. The detected regions can be further used for more complicated computer vision applications such as object detection and recognition, image compression, content-based image editing, and image retrieval.

  4. 17. Radiation Detection Techniques for the Enhancement of Nuclear Safety

    Author : Petty Bernitt Cartemo; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; whole body counting; depth profiling; voxel phantom; nuclear safeguards; Monte Carlo; orphan sources; radiation-induced material damage; pulsed beam; positron lifetime;

    Abstract : The hazard originating from the use of nuclear materials in various areas of the society necessitates a number of experimental techniques for controlling and increasing the safety connected to radioactive substances.The following thesis is divided into two parts, representing different aspects to the detection of radiation effects.

  5. 18. Elicitation and enhancement of T and B cell responses

    Author : Hannes Uchtenhagen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The Major histocompatibility complex class I (MHC-I) has been characterized in such great depth that a number of its key properties are well understood and part of its behavior can even be predicted. It is therefore intriguing that the impact of small epitope modifications on immunogenicity and the elicitation of T-cell repertoires remain often unpredictable and full of surprises. READ MORE

  6. 19. Enhancement of Volatile Fatty Acid Production from Dairy Wastewater

    Author : Merve Atasoy; Zeynep Cetecioglu; Juan Lema; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volatile fatty acid; mixed culture fermentation; pure culture; bioaugmentation; bacterial community; Flyktiga fettsyror; jäsning med blandkultur; renkultur; bioaugmentering; bakteriesamhälle; Chemical Engineering; Kemiteknik;

    Abstract : Resource recovery from waste-streams is a highly promising approach to meet with urbanization and modernization consequences. Rapid human population growth, expanding industrialization and excessive consumption of resources lead to increasing demand for raw materials and energy sources, and an escalation of greenhouse gas emission.

  7. 20. Speech Signal Extraction : A Multichannel Approach

    Author : Nedelko Grbic; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Speech Enhancement; Blind signal separation; Echo control; Adaptive systems;

    Abstract : In speech signal extraction the aim is to extract human speech in a physical environment by using microphones. In any real world environment there are many disturbance sources that cause unwanted sound pressure, which in turn may degrade the comprehension of the speech at the microphones. READ MORE
