  1. 1. Industrial Digital Fabrication Using Inkjet Technology

    Författare :Ingo Reinhold; Carl-Mikael Zetterling; Matti Mäntysalo; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  2. 2. Enabling Internet-Scale Publish/Subscribe In Overlay Networks

    Författare :Fatemeh Rahimian; Seif Haridi; Šarunas Girdzijauskas; Márk Jelasity; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Publish Subscribe; Content Distribution; Peer-To-Peer Overlay Network; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : As the amount of data in todays Internet is growing larger, users are exposedto too much information, which becomes increasingly more difficult tocomprehend. Publish/subscribe systems leverage this problem by providingloosely-coupled communications between producers and consumers of data ina network. Data consumers, i.e. LÄS MER
