  1. 1. Two-Barrier Problems in Applied Probability: Algorithms and Analysis

    Författare :Mats Pihlsgård; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; operations research; programming; actuarial mathematics; Statistik; Matematik; Mathematics; Naturvetenskap; Natural science; Reflection; Stochastic processes; Applied probability; Queueing; operationsanalys; programmering; aktuariematematik;

    Sammanfattning : This thesis consists of five papers (A-E). In Paper A, we study transient properties of the queue length process in various queueing settings. We focus on computing the mean and the Laplace transform of the time required for the queue length starting at $x0. We define the loss rate due to the reflection. LÄS MER

  3. 2. Performance Analysis and Optimization via Simulation

    Författare :Anders Svensson; Institutionen för informatik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; performance analysis; load sharing; mathematical model formalism; real-time control; design; Telecommunication engineering; modular optimization; circuit switched networks; Telekommunikationsteknik;

    Sammanfattning : A large amount of scientific work has been carried out to enhance the methods used for design and control of technical systems. For many of these systems, the main objective is to utilize the limited resources in an optimal way. Different simulation techniques have, in many cases, been successfully applied to the analysis.

  4. 3. Age of Information Aware Communication Systems : Modeling and Performance Analysis

    Författare :Antzela Kosta; Vangelis Angelakis; Nikolaos Pappas; Viktoria Fodor; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Advances in wireless communications and networking technology have taken us towards a pervasively connected world in which a vast array of wireless devices, from mobile phones to environmental sensors, seamlessly communicate with each other. In many of these systems the freshness of the transmitted information is of high importance. LÄS MER

  5. 4. Window-based congestion control : Modeling, analysis and design

    Författare :Niels Möller; Karl Henrik Johansson; Rayadurgam Srikant; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internet; Congestion control; Window-based; Telecommunication; Telekommunikation;

    Sammanfattning : This thesis presents a model for the ACK-clock inner loop, common to virtually all Internet congestion control protocols, and analyzes the stability properties of this inner loop, as well as the stability and fairness properties of several window update mechanisms built on top of the ACK-clock. Aided by the model for the inner-loop, two new congestion control mechanisms are constructed, for wired and wireless networks. LÄS MER

  7. 5. Analysis of Lateral Transshipments in Inventory Systems

    Författare :Stefan Vidgren; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Queueing theory; Inventory control; Stochastic; Lateral transshipments; Optimization;

    Sammanfattning : This thesis is based on two scientific papers. In these papers we study how one can approximate the inventory level of probabilities and the transshipment rates for inventory systems that apply lateral transshipment policies. LÄS MER
