  1. 6. Heuristic Mathematical Programming Methods for Lot-sizing, Inventory Control, and Distribution Cost Estimation in the Supply Chain

    Författare :Björn Samuelsson; Athanasios Migdalas; Anders Segerstedt; Sven Axsäter; Leonidas Pitsoulis; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic lot size; Multi-echelon inventory systems; Supply network optimization; Distribution; Location analysis; Distribution cost approximation; Industrial Logistics; Industriell logistik;

    Sammanfattning : The supply function has an important role to support the business to create a customer value. Two important parts of this process is to have the warehouses and production sites in the right location and to have the right items stocked at the right level. This thesis is concerned with those two parts of the supply chain management.

  3. 7. Seismicity Analyses Using Dense Network Data : Catalogue Statistics and Possible Foreshocks Investigated Using Empirical and Synthetic Data

    Författare :Angeliki Adamaki; Roland Roberts; Beata Orlecka-Sikora; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistical Seismology; Earthquake Catalogue Statistics; Seismicity Patterns; Precursors; Foreshocks; Στατιστική Σεισμολογία; Κατάλογοι Σεισμών; Μοτίβα Σεισμικότητας; Πρόδρομα Φαινόμενα; Προσεισμοί; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : Precursors related to seismicity patterns are probably the most promising phenomena for short-term earthquake forecasting, although it remains unclear if such forecasting is possible. Foreshock activity has often been recorded but its possible use as indicator of coming larger events is still debated due to the limited number of unambiguously observed foreshocks. LÄS MER

  4. 8. Antennas, Wave Propagation, and Localization in Wireless Body Area Networks

    Författare :Rohit Chandra; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Body Area Network; WBAN; body sensor network; body-centric communication; wearable devices; ear-to-ear propagation; antennas; analytical propagation model; localization; wireless capsule endoscopy; in-mouth device; implants;

    Sammanfattning : A network of communicating wireless devices that are implantable, wearable or within close proximity of a human body is called wireless body area network (WBAN). The propagation channels for the devices in the WBAN are either through the body or over the body. LÄS MER

  5. 9. Triad count estimation and transitivity testing in graphs and digraphs

    Författare :Martin Karlberg; Tom Snijders; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; Statistik; statistik; Statistics;

    Sammanfattning : Triads and transitivity are two concepts within the field of social network analysis that are closely related to each other. We study some estimation and testing problems related to those concepts, using the tools of graph theory; the results obtained could be applied to graphs representing other kinds of data than social relations.

  7. 10. Data Integrity and Availability in Power System Communication Infrastructures

    Författare :Ognjen Vuković; György Dán; Deepa Kundur; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyber security; power systems; communications; state estimation; distributed;

    Sammanfattning : Society is increasingly dependent on the proper functioning of electric power systems. Today's electric power systems rely heavily on information and networking technology in order to achieve efficient and secure operation. LÄS MER
