  1. 21. Optimization and control of feed and transfer pumps

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Carlos Jorques Moreno; [2014]
    Nyckelord :Technology and Engineering;

    Sammanfattning : A new low pressure fuel system implementation for Scania’s trucks is being investigated. The main challenge consists in exchanging the mechanical pump with electrical pumps. The electrical pumps must then be controlled to supply exactly the demanded amount of fuel at the required pressure. LÄS MER

  3. 22. Extension of the Benchmark Simulation Model no. 2 with a model for chemical precipitation of phosphorus

    Uppsats för yrkesexamina på avancerad nivå, Reglerteknik

    Författare :Sofie Bydell; [2013]
    Nyckelord :BSM2; phosphate; phosphorus; chemical precipitation; wastewater treatment; BSM2; fosfat; fosfor; kemisk fällning; reningsverk;

    Sammanfattning : At present, there are more than 2000 wastewater treatments plants (WWTPs) in Sweden. Emissions of nitrogen and phosphorus from these, do contribute to the eutrophication of the Baltic Sea and watercourses on a daily basis. To reduce emissions of phosphorus, the Swedish approach has for the last 50 years been to use chemical precipitation. LÄS MER

  4. 23. Val av teknik för hastighetsmätning i kallvalsverk

    Uppsats för yrkesexamina på grundnivå, Industriell teknik

    Författare :Martin Öling; [2013]
    Nyckelord :;

    Sammanfattning : An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. LÄS MER

  5. 24. Optimization of Valve Damping

    Master-uppsats, Fluida och mekatroniska system; Tekniska högskolan

    Nyckelord :;

    Sammanfattning : Öhlins CES Technologies in Jönköping have in the last 30 years been developing control valves for semi active suspension systems used in the car industry. The system, marketed by Öhlins under the brand name CES (Continuously controlled Electronic Suspension), enables a wide working range and ability to adapt to the current road conditions. LÄS MER

  7. 25. Work Zone's Capacity Estimation and Investigation of Potential of Dynamic Merge Systems

    Master-uppsats, Kommunikations- och transportsystem; Tekniska högskolan

    Författare :Daniel Furda; Bahareh Bagherzadeh Saffarian; [2012]
    Nyckelord :Work zone; dynamic merge; alinea; aimsun; microsimulation;

    Sammanfattning : Work zones are an essential part of roads maintenance. Despite all the efforts addressed to reduce work zone’s negative impacts on the road traffic performance and improve the road safety, there still exist work zone related congestions and traffic problems. LÄS MER
