  1. 1. Real-Time Optimization of Cone Crushers

    Författare :Erik Hulthén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process optimization; crushing; CSS; real-time optimization; eccentric speed; cone crusher;

    Sammanfattning : Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation and production of rock materials. Cone crusher control systems are widely used for machine protection, wear compensation and, to some extent, increasing production. These systems ordinarily focus on the crusher and not the yield of production process. LÄS MER

  3. 2. Development of speed-power performance models for ship voyage optimization

    Författare :Xiao Lang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-scale measurements; speed-power performance; added resistance due to waves; energy efficiency; machine learning; voyage optimization;

    Sammanfattning : Various measures, such as voyage optimization, performance monitoring and ship cleaning schedules, have been developed to help increase the energy efficiency of shipping operations. One of the most important elements needed for these measures is a reliable ship speed-power model. LÄS MER

  5. 4. Modeling, Optimization and Analysis of Electromobility Systems

    Författare :Gabriel Domingues; Industriell elektroteknik och automation; []
    Nyckelord :Electromobility; Electric Vehicles; Hybrid Vehicles; Charging; Modeling; Optimization;

    Sammanfattning : Due to an increase in environmental awareness and an improved understanding on the impact of human activity on our planet’s climate, there is a strong desire both from governments and the general public to reduce harmful pollution and emissions. This requires action on different fronts, like decarbonizing electricity generation, industrial activity and not least the transport sector. LÄS MER

  7. 5. Applications of Resource Optimization in Wireless Networks

    Författare :Patrik Björklund; Peter Värbrand; Mikael Johansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; telecommunication; scheduling; gsm; wcdma; ad-hoc; frequency planning; Telecommunication; Telekommunikation;

    Sammanfattning : The demand for wireless communications is increasing every year, but the available resources are not increasing at the same rate. It is very important that the radio resources are used in an efficient way allowing the networks to support as many users as possible. LÄS MER
