  1. 1. Moving Networks, a Better Way to Serve Vehicular Users

    Författare :Sui Yutao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; small cells; device-to-device communication; vehicular small cells; Moving relay node; moving cells; moving networks; interference management; ultra-dense networks; vehicular penetration loss;

    Sammanfattning : Nowadays, a great number of mobile broadband users are vehicular. It is very common that people are using their mobile devices either for working or entertainment when they are on the go. We are expecting mobile broadband to offer comparable experience everywhere, e.g. LÄS MER

  3. 2. Sampling from large flotation cells : An invastigation of spatial distribution

    Författare :Lisa Malm; Jan Rosenkranz; Tommy Karlkvist; Anders Sand; Nils-Johan Bolin; Pertti Lamberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flotation; sampling; Mineral Processing; Mineralteknik;

    Sammanfattning : The general trend in flotation technology today is towards larger flotation cells, which enables a higher throughput. However, adverse effects such as segregation and reduced froth transport efficiency have also been observed in larger cells. LÄS MER

  4. 3. Specific and nonspecific immune mechanisms in human gut : a comparative study of normal and ulcerative colitis intestine

    Författare :Moorix Mo-Wai Yeung; Sten Hammarström; Marie-Louise Hammarström; Marita Troye-Blomberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human intestine; ulcerative colitis; lymphoid aggregates; intraepithelial lymphocytes; lamina propria lymphocytes; γδT-cells; cytokines; IL-2; carcinoembryonic antigen; biliary glycoprotein; epithelial cells; glycocalyx;

    Sammanfattning : The intestine, with its large mucosal surface area, digests and absorbs food nutrients and maintains a beneficial microbial flora in the colon. Local protective immune responses against intestinal pathogens ensure the survival of the individual. These immune reactions are both specific and non-specific in nature. LÄS MER

  5. 4. Protein Recovery Using Simulated Moving Bed Technology and Macroporous Chromatographic Support Material

    Författare :Jonatan Andersson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; Chromatography; Simulated Moving Bed; Protein;

    Sammanfattning : Due to its gentle and high resolving power, chromatography is the work horse within protein separation. Still it is an expensive method due to low productivity, diluted product streams, large waste streams and expensive support material. This limits its potential use to areas of high price products.

  7. 5. Optimization of Manufacturing Cells Using Discrete Event Models

    Författare :Avenir Kobetski; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Flexible Manufacturing; Optimal Scheduling; Supervisory Control Theory; A*; Velocity Balancing; Discrete Events Systems; Mixed Integer Linear Programming; Timed Deterministic Finite Automata; Robot Coordination; Visibility Graphs;

    Sammanfattning : As the name suggests, this thesis is concerned with flexible manufacturing systems (FMS) and their way of living. More specifically, the main objective of this workis to generate working schedules for the moving objects of the manufacturing cells. LÄS MER
