  1. 21. Low Cycle Fatigue Weld Optimization using Chaboche Material Model

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Louise Rosenblad; Filippa Hallbäck; [2018]
    Nyckelord :;

    Sammanfattning : In this master thesis a method for optimizing welds has been investigated. The method was developed by the use of a finite element (FE)-model of a silencer. The silencer is exposed to both dynamic and thermal loads. Focus has been on using topology optimization for the welds. LÄS MER

  3. 22. Press Measurements and Virtual Rework of Stamping Dies

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Einar Palsson; Mårten Hansson; [2017]
    Nyckelord :Virtual Rework; Inverse Modeling; ARAMIS Digital Image Correlation DIC ;

    Sammanfattning : Stamping dies are used in the Sheet Metal Forming (SMF) process for manufacturing of car body parts. The lead time for design and manufacturing of a stamping die is long, and therefore costly. LÄS MER

  4. 23. Spatio-temporal Traffic Flow Prediction

    Master-uppsats, KTH/Geoinformatik

    Författare :Mesele Atsbeha Gebresilassie; [2017]
    Nyckelord :ITS; principal component analysis; spatio-temporal traffic flow; spatially weighted regression; traffic flow prediction; support vector machine for regression;

    Sammanfattning : The advancement in computational intelligence and computational power and the explosionof traffic data continues to drive the development and use of Intelligent TransportSystem and smart mobility applications. As one of the fundamental components of IntelligentTransport Systems, traffic flow prediction research has been advancing from theclassical statistical and time-series based techniques to data–driven methods mainly employingdata mining and machine learning algorithms.

  5. 24. Structural Analysis & Weight Optimization : Wheel Loader Front Axle Casings

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Georg Svedling; Erik Wikblom; [2017]
    Nyckelord :Wheel Loader; Weight Optimization; Topology Optimization; Strucutral Analysis; Mechanical Desing; Axle Casing;

    Sammanfattning : The purpose of this thesis work was to establish methodologies for performing structural analysis and weight optimization of wheel loader front axle casings at Volvo Construction Equipment AB (Volvo CE). A methodology for creating extensive finite element models to analyze durability with respect to both static failure and fatigue life was to be created in the software ANSYS 18. LÄS MER

  7. 25. Modeling Control Traffic in Distributed Software Defined Networks

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Muhammd Zeshan Naseer; [2016]
    Nyckelord :;

    Sammanfattning : Software defined networks (SDNs) have evolved as novel network architecture in modern networking. However, to allow SDN scale for several thousand switches, the control architecture needs to be distributed, with control traffic between switches and controllers, as well as among the controllers.
