  1. 16. Simulation and Measurement of Wheel on Rail Fatigue and Wear

    Författare :Babette Dirks; Mats Berg; Roger Enblom; Mark Burstow; KTH; []
    Nyckelord :multibody simulations; prediction; wear; RCF; wheel; rail; cracks; measurements; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The life of railway wheels and rails has been decreasing in recent years. This is mainly caused by more traffic and running at higher vehicle speed. LÄS MER

  3. 17. Fundamental Limits in Wireless Wideband Networking

    Författare :Tan Tai Do; Mikael Skoglund; Tobias Oechtering; Olav Tirkkonen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The rapid growth of the wireless communication industry recently does not only bring opportunities but also challenges on developing radio technologies and solutions that can support high data rate as well as reliable and efficient communications. Two fundamental factors that limit the transmission rate are the available transmit energy and the available bandwidth. LÄS MER

  4. 18. On Application Oriented Experiment Design for Closed-loop System Identification

    Författare :Afrooz Ebadat; Bo Wahlberg; Torsten Söderström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; closed-loop identification; experiment design for identification;

    Sammanfattning : System identification concerns how to construct mathematical models of dynamic systems based on experimental data. A very important application of system identification is in model-based control design. In such applications it is often possible to externally excite the system during the data collection experiment. LÄS MER

  5. 19. Places on Becoming : An Ethnographic Case Study of a Changing City and its Emerging Residential Environments

    Författare :Alazar Ejigu; Tigran Haas; Roderick Lawrence; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; place; placemaking; large-scale housing; ethnography; modernity; condominiums; Addis Ababa; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : Some places which once were celebrated by many slowly become places of desolation and social problem while others built with similar intentions and forms continue to flourish. This is typically true of a number of large residential neighbourhoods of Post-World War II Europe and many cities of the global South. LÄS MER
