  2. 21. Printed RFID Humidity Sensor Tags for Flexible Smart Systems

    Author : Yi Feng; Werner Zapka; Li-Rong Zheng; Qiang Chen; Donald Lupo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intelligent packaging; humidity sensor; wireless sensor; chipless RFID; multi-walled carbon nanotube; inkjet printing; LC resonator; paper electronics; flexible electronics.;

    Abstract : Radio frequency identification (RFID) and sensing are two key technologies enabling the Internet of Things (IoT). Development of RFID tags augmented with sensing capabilities (RFID sensor tags) would allow a variety of new applications, leading to a new paradigm of the IoT. READ MORE

  4. 22. Influence of Water on Coarse Granular Road Material Properties

    Author : Jonas Ekblad; Ulf Isacsson; Hervé Di Benedetto; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Highway Engineering; Granulat materials; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : Even though the practical experience of using coarse unbound granular materials is extensive, detailed knowledge on the mechanical and hydraulic behavior is to a large extent lacking. Regarding influence of water on mechanical properties, this is even more pronounced. READ MORE

  5. 23. Sustainability of irrigated agriculture under salinity pressure – A study in semiarid Tunisia

    Author : Fethi Bouksila; Avdelningen för Teknisk vattenresurslära; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : In semiarid and arid Tunisia, water quality and agricultural practices are the major contributing factors to the degradation of soil resources threatening the sustainability of irrigation systems and agricultural productivity. Nowadays, about 50% of the total irrigated areas in Tunisia are considered at high risk for salinization. READ MORE

  6. 24. Electromagnetic Dispersion Modeling and Analysis for Power Cables

    Author : Stefan Gustafsson; Sven Nordebo; Alexander Nosich; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; power cable; electromagnetic model; dispersion relation; asymptotic analysis; sensitivity analysis;

    Abstract : This thesis addresses electromagnetic wave propagation in power cables. It consists of five papers, where the three first papers are based on one and the same model, and the last two papers are based on a similar but slightly different model. READ MORE

  7. 25. Towards understanding breakage and flow in sublevel caving (SLC) : Development of new measurement techniques and results from full-scale tests

    Author : Matthias Wimmer; Pekka Särkkä; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : Blast function, fragmentation and gravity flow are core elements for sublevel caving (SLC). For the ore recovery to be as high and the waste rock dilution as low as possible all three elements have to work as planned. READ MORE
