  1. 6. An add-on filter technique to improve micropollutant removal and water quality in on-site sewage treatment facilities

    Författare :Wen Zhang; Gunno Renman; Erik Kärrman; Carlos Alberto Arias; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micropollutant; on-site sewage facilities; physicochemical properties; pore structure; sorbents; surface functional group; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Onsite sewage treatment facilities (OSSFs) in Sweden currently release significant amounts of nitrogen (N) and phosphorus (P) into groundwater or/and receiving water bodies. Micropollutants (MPs) have been found in both surface water and groundwater, indicating insufficient removal of MPs by OSSFs. LÄS MER

  3. 7. Regulation of thromboinflammation in therapeutic medicine : Special focus on surface coating strategies

    Författare :Sana Asif; Bo Nilsson; Christine Skerka; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Biomaterials are an integral part of modern health care and offer potential treatment modalities to diseases and conditions otherwise intractable. However, the critical issue herein is incompatibility reactions. LÄS MER

  4. 8. Spatio-Temporal Pre-Processing Methods for Region-of-Interest Video Coding

    Författare :Linda S. Karlsson; Tingting Zhang; Mårten Sjöström; Youzhi Xu; Apostolos Georgakis; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Region-of-interest; video coding; pre-processing; spatio-temporal filters; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : In video transmission at low bit rates the challenge is to compress the video with a minimal reduction of the percieved quality. The compression can be adapted to knowledge of which regions in the video sequence are of most interest to the viewer. LÄS MER

  5. 9. Automated feature detection in multidimensional images : a unified tensor approach

    Författare :Einar Heiberg; Klas Nordberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Manual identification of structures and features in multidimensional images is at best time consuming and operator dependent. Feature identification need to be accurate, repeatable and quantitative. This thesis presents a unified approach for automatic feature detection in multidimensional scalar and vector fields. LÄS MER

  7. 10. Implementation of digital-serial LDI/LDD allpass filters

    Författare :Krister Landernäs; Johnny Öberg; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik; Elektronik;

    Sammanfattning : In this thesis, digit-serial implementation of recursive digital filters is considered. The theories presented can be applied to any recursive digital filter, and in this thesis we study the lossless discrete integrator (LDI) allpass filter. LÄS MER
