  1. 31. On Integrity Monitoring of Integrated Navigation Systems

    Författare :Jan Palmqvist; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In civil aviation a new philosophy for flight safety and traffic management is under development. The goal is to enable an expected increase in air traffic density by reducing aircraft separation. The accuracy of the position estimate determined by the navigation system in each aircraft determines this separation. LÄS MER

  3. 32. Rock Mass Characterisation Using Drill Performance Monitoring : Problems, Analysis challenges and Limitations

    Författare :Rajib Ghosh; Piyush Rai; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Sammanfattning : In open pit mining, it is important to know as much information as possible about rock masses to be mined for more cost-effective mining operation. In rock engineering perspective, information about rock mass characteristics usually includes hardness of the rock, geological features, fractures, faults, ore contacts, water bearing stratum.

  4. 33. Over-the-Air Computation for Machine Learning: Model Aggregation via Retransmissions

    Författare :Henrik Hellström; Carlo Fischione; Viktória Fodor; Kaibin Huang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Communications; Machine Learning; Over-the-Air Computation; Federated Learning; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : With the emerging Internet of Things (IoT) paradigm, more than a billion sensing devices will be collecting an unprecedented amount of data. Simultaneously, the field of data analytics is being revolutionized by modern machine learning (ML) techniques that enable sophisticated processing of massive datasets. LÄS MER

  5. 34. Self Assembly at the Liquid Air Interface

    Författare :Niga Petru; Rutland Mark; Ye Shen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; VSFS; SFG; interface; crown ethers; ethylene oxides; ionic liquids; fatty acids; domains.; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : The aim of this work is to study the interfacial properties of amphiphilic compounds at the liquid–air interface in an attempt to develop a comprehensive understanding of their orientation as well as the influence of their interaction with the solvent on the interfacial layer properties. Using Vibrational Sum Frequency Spectroscopy (VSFS) as the main tool, the molecular structure of the amphiphilic layer and the amphiphile–solvent relation can be illuminated in great detail – it is arguably the most sensitive surface spectroscopy currently available.

  7. 35. Training measures and technologies for air contaminant risks

    Författare :Karl Gummesson; Marianne Ekman Rising; Ing-Marie Andersson; Gunnar Rosén; Annika Vänje; Mats Bohgard; KTH; []
    Nyckelord :Arbetsmiljö; Attityd; Motivation; Utbildning; Industriell ekonomi och organisation; Industrial Engineering and Management;

    Sammanfattning : AbstractAs air contaminants continue to pose a problem in organizations, more studies are needed to identify and reduce employees’ exposure to air contaminants. Limited research proposes methods for managing air contaminants, especially with focus on reducing exposure by improving safety behavior, safety knowledge, safety attitudes and safety motivation among employees in the workplace, by, for instance, using safety training.
