  1. 1. Environmental Modeling and Uncertainty

    Författare :Muhammad Sarfraz Iqbal; Dik van de Meent; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QSAR; multimedia fate modeling; uncertainty analysis; probability bounds analysis; fuzzy arithmetic; chemical safety assessment; REACH;

    Sammanfattning : Environmental fate models are used to evaluate the fate and effects of chemicals for risk assessment. Fate models may be effective and low-cost substitutes for field measurements and are helpful to project future scenarios. LÄS MER

  3. 2. On Perception-Based Error Protection for Mobile Multimedia

    Författare :Muhammad Imran Iqbal; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Representation of multimedia requires large amounts of data. Therefore, multimedia source signals are compressed to reduce the data rate that would otherwise be required for its transmission. However, compression renders multimedia data more vulnerable to transmission errors. LÄS MER

  4. 3. Preferential Coding for Mobile Multimedia Services

    Författare :Muhammad Imran Iqbal; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Different parts of source encoded multimedia streams such as those associated with standard image or video formats possess different levels of importance with respect to their contribution to the quality of the reconstructed image or video. This unequal importance among data within a codestream gives rise to preferential treatment of the more significant parts of the codestream compared to the less important parts. LÄS MER

  5. 4. Mesoporous Silica Particles for a Potential Therapeutic Application

    Författare :Muhammad Naeem Iqbal; Niklas Hedin; Tore Bengtsson; Mirva Eriksson; Jessica Rosenholm; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mesoporous silica; SBA-15; amylase; lipase; electron microscope; adsorption; type 2 diabetes; materialkemi; Materials Chemistry;

    Sammanfattning : Mesoporous silica particles (MSPs) have a high surface area, pore volume, and tunable pore size and surface properties, which makes them ideal for advanced therapeutic, biocatalytic, separation, and drug delivery applications. The work in this thesis shows that MSPs can be employed for therapeutic applications with minimal risk of adverse consequences. LÄS MER
