  5. 4. Enhancing Tropospheric Humidity Data Records from Satellite Microwave and Radiosonde Sensors

    Författare :Isaac Moradi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CDR; climate; microwave; radiosonde; water vapor; remote sensing; antenna; homogenization; humidity; meteorology; troposphere; radio-frequency;

    Sammanfattning : Water vapor is the most dominant greenhouse gas and plays a critical role in the climate by regulating the Earth's radiation budget and hydrological cycle. A comprehensive dataset is required to describe the temporal and spatial distribution of water vapor, evaluate the performance of climate and weather prediction models in terms of simulating tropospheric humidity, and understand the role of water vapor and its feedback in the climate system.

  7. 5. Sensing capability of nanomodified Portland cement composites

    Författare :Thanyarat Buasiri; Andrzej Cwirzen; Karin Habermehl-Cwirzen; Jan Olek; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensing cementitious composites; nanomodified Portland cement; Carbon nanofibers; CNF; piezoresistive materials; sensor; cement-based sensor; self-monitoring; sensing capability; Byggmaterial; Building Materials;

    Sammanfattning : Sensing cement-based composites refer to composites that have sensing functionality that can measure several physical and chemical parameters. Sensing cement-based composites are fabricated by incorporating some functional fillers, such as conductive fibers (CFs), carbon nanofibers (CNFs), carbon nanotubes (CNTs), and graphene, into conventional concrete.
