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

    Author : Björn Samuelsson; Athanasios Migdalas; Anders Segerstedt; Sven Axsäter; Leonidas Pitsoulis; Luleå tekniska universitet; []
    Keywords : 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;

    Abstract : 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.

  4. 2. Fault location in resonant earthed medium voltage distribution systems

    Author : Md Zakaria Habib; Nathaniel Taylor; Mohamed F. Abdelfattah; Matti Lehtonen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical distribution; Distribution network; Reliability; SAIDI; Fault location; FL; Fault passage indicator; FPI; Compensated neutral; Resonant earthing; Resonant grounding; Petersen coil; Arc suppression coil.; Distributionsnät; Tillförlitlighet; Fellokalisering; FL; Felpassageindikation; FPI; Kompenserat nät; Spoljordat nät; Petersenspole.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : A major challenge in electric distribution systems is to increase the reliability of the electricity supply in an economical way. At the final medium-voltage level in the system, such as 10 kV or 20 kV, a single feeder may supply tens of medium/low-voltage transformers and hundreds of customers, with many branches of lines and cables where faults can occur.

  5. 3. Dryout and Power Distribution Effects in Boiling Water Reactors

    Author : Carl Adamsson; Henryk Anglart; Barry Azzopardi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dryout; Film flow analysis; Power distribution; Measurements; Subchannel; Atomic physics; Atomfysik;

    Abstract : Film flow measurements at several axial positions in round pipes with variousaxial power distributions are presented for conditions corresponding to normaloperation of a BWR. It is confirmed that the film flow rate approaches zero atthe onset of dryout. READ MORE

  6. 4. Asymptotics of Eigenpolynomials of Exactly-Solvable Operators

    Author : Tanja Bergkvist; Boris Shapiro; Andrei Martinez-Finkelshtein; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; exactly-solvable; eigenpolynomials; zero distribution; asymptotics; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Abstract : The main topic of this doctoral thesis is asymptotic properties of zeros in polynomial families arising as eigenfunctions to exactly-solvable differential operators. The study was initially inspired by a number of striking results from computer experiments performed by G. Masson and B. Shapiro for a more restrictive class of operators. READ MORE

  7. 5. Ethical Issues in the Adoption and Implementation of Vision Zero Policies in Road Safety

    Author : Henok Girma Abebe; Karin Edvardsson Björnberg; Sven Ove Hansson; Matts-Åke Belin; Elin Palm; KTH; []
    Keywords : HUMANIORA; HUMANITIES; Ethics; Equity; Road Safety; Vision Zero; Responsibility; Systems Thinking; Risk; Drivin; Philosophy; Filosofi;

    Abstract : The aim of this doctoral thesis is to analyze ethical issues in the adoption and implementation of Vision Zero policies. The first article analyses criticisms against Vision Zero goals and measures promoted to reach them. We identify and assess “moral”, “operational”, and “rationality-based” arguments against Vision Zero. READ MORE
