  1. 21. Strategic Maintenance Development in Manufacturing Industry

    Författare :Antti Salonen; Mats Deleryd; Marcus Bengtsson; Pra Murthy; Mälardalens högskola; []
    Nyckelord :Innovation and Design; innovation och design;

    Sammanfattning : Industrial maintenance is a substantial financial post. The total value of maintenance budgets in Europe has been estimated to be approximately 1500 billion € per year. At the same time, there are indications that about a third of these costs are wasted due to poor planning, overtime costs, inferior use of preventive maintenance and so forth. LÄS MER

  3. 22. Seasonal turnover in groundwater

    Författare :Maria Engström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : This Licentiate Thesis presents a new approach of understanding leakage in agricultural land. Former studies concentrate on long term measurement of different pollutants in nearby watercourses and streams. The new approach is so far only numerically performed, but will soon be complemented by laboratory tests and field measurements. LÄS MER

  4. 23. Ventilation Performance in Operating Rooms : A Numerical Assessment

    Författare :Cong Wang; Sture Holmberg; Sasan Sadrizadeh; Anna Bogdan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating room ventilation; bacteria-carrying particles; laminar airflow; mixing ventilation; temperature-controlled airflow; computation fluid dynamics; Lagrangian particle tracking; Civil and Architectural Engineering; Byggvetenskap; Strömnings- och klimatteori; Fluid and Climate Theory;

    Sammanfattning : Surgical site infections (SSIs) remain one of the most challenging postoperative complicationsof healthcare and threaten the lives of millions of patients each year. Current evidence hasshown a positive relationship between the airborne concentration of bacteria-carryingparticles (BCPs) in the operating room (OR) and the rate of infections. LÄS MER

  5. 24. Dependable Path Planning for Autonomous Control

    Författare :LanAnh Trinh; Mikael Ekström; Baran Cürüklü; Federico Pecora; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

    Sammanfattning : Changing from automatic to autonomous control has emerged as the main shift on the development of robots nowadays. The autonomous control allows robot to have more freedom as well as direct interactions with human and other robots. Having a dependable platform for autonomous control becomes crucial when building such a system. LÄS MER

  7. 25. The EEG of the Newborn Brain - Detection of Hypoxia and Prediction of Outcome

    Författare :Nils Löfgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; telemedicine; neonatal; prediction; infraslow EEG; cerebral; entropy; asphyxia; EEG; VLFA; hypoxia; Kolmogorov complexity; qEEG; detection; spectral estimation; newborn;

    Sammanfattning : Brain function requires a continuous flow of oxygen and an insufficient supply (hypoxia) for a few minutes during the first period of life may have severe consequences; consequences which might impact both the life of the individual who has been struck and his or her family. Therefore, there is a need to find a method which can enable the detection of an insufficient oxygen supply at an early stage, before brain damage becomes permanent. LÄS MER
