  1. 1. Modelling of Traffic Loads on Bridges Based on Measurements of Real Traffic Loads in Sweden

    Författare :Fredrik Carlsson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy vehicles; traffic intensity; Peaks Over Thresholds; axle and bogie pressure; traffic load effects; probability based classification; Technological sciences; Teknik;

    Sammanfattning : This thesis treats traffic load effects in road bridges and in particular bending moment and shear force in different types of bridges. All traffic load effects are described in terms of statistical distribution functions for annual extreme values. LÄS MER

  3. 2. Traffic Load Effects on Bridges, Statistical Analysis of Collected and Monte Carlo Simulated Vehicle Data

    Författare :Abraham Getachew; KTH; []
    Nyckelord :bridge; traffic load; transverse distribution; characteristic value; weigh in motion;

    Sammanfattning : Research in the area of bridge design has been and still isconcentrated on the study of the strength of materials andrelatively few studies have been performed on traffic loads andtheir effects. Traffic loads have usually been assumed to begiven in codes. LÄS MER

  4. 3. Analysis of traffic load effects an railway bridges

    Författare :Gerard James; KTH; []
    Nyckelord :bridge; rail; traffic load. Load effect. Dynamic amplification factor; extreme value theor; peaks-over-threshold;

    Sammanfattning : The work presented in this thesis studies the load and loadeffects of traffic loads on railway bridges. The increasedknowledge of the traffic loads, simulated using fieldmeasurements of actual trains, are employed in a reliabilityanalysis in an attempt at upgrading existing railwaybridges. LÄS MER

  5. 4. Future Train Traffic Control : Development and deployment of new principles and systems in train traffic control

    Författare :Gunnika Isaksson-Lutteman; Bengt Sandblad; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

    Sammanfattning : The train traffic control system of the future requires new solutions and strategies in order to better meet tomorrow’s demands and goals. Uppsala University and Trafikverket have been collaborating for several years in research regarding train traffic control and how to improve traffic controllers’ support systems and working environment.

  7. 5. Traffic Management in Software-Defined Data Center Networks

    Författare :Cristian Hernandez Benet; Andreas Kassler; Boris Koldehofe; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SDN; data center; load-balancing; traffic management; EVPN; big data; programmable data plane; Computer Science; Datavetenskap;

    Sammanfattning : Traffic management in data centers is paramount to improving network and application performance, thereby improving the quality of service by reducing network congestion, packet loss, and latency. However, the deployment and configuration of traffic management techniques are challenging due to diverse data-center traffic characteristics, large data center topologies, and the interplay of different protocols at the routing, transport, and link layer.
