  2. 11. Industrial Digital Fabrication Using Inkjet Technology

    Author : Ingo Reinhold; Carl-Mikael Zetterling; Matti Mäntysalo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inkjet printing; droplet formation; digital fabrication; sintering; nanoparticles; printed electronics; Industrial Information and Control Systems; Industriella informations- och styrsystem; Media Technology; Medieteknik; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : The use of acoustic waves initiated by the deformation of a microchannel is one method for generating monodisperse, micrometer-sized droplets from small orifices and is employed in piezo-electric inkjet printheads. These printheads are used in both graphical printing and digital fabrication, where functionalities, such as optical, biological, electrical or mechanical, are being produced locally. READ MORE

  4. 12. Distributed File System Metadata and its Applications

    Author : Mahmoud Ismail; Jim Dowling; Seif Haridi; Luis Veiga; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Distributed hierarchical file systems typically decouple the storage and serving of the file metadata from the file contents (file system blocks) to enable the file system to scale to store more data and support higher throughput. We designed HopsFS to take the scalability of the file system one step further by also decoupling the storage and serving of the file system metadata. READ MORE

  6. 14. A Feasibility Study of Wireless Networks for 17 and 60 GHz and the Impact of Deployment Strategies on the System Performance

    Author : Matthias Unbehaun; Jens Zander; Gerald Q. Jr. Maguire; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Information technology; Informationsteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : This thesis addresses the question of how to deploy the infrastructure for wireless networks carrying high data rate services. It starts from the assumption that a major part of the costs for installing wireless infrastructure is caused by antenna site acquisition, planning of network coverage and capacity as well as manpower for setting up and wiring the antenna sites.
