  1. 11. 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. 12. Towards the Limits of Nonlinearity Compensation for Fiber-Optic Channels

    Författare :Naga Vishnukanth Irukulapati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Viterbi algorithm; fiber-optic channel; stochastic digital backpropagation; performance limits; factor graphs; near-MAP detector; Digital backpropagation; nonlinear compensation; mutual information;

    Sammanfattning : The performance of long-haul coherent optical systems is fundamentally limited by fiber nonlinearity and its interplay with chromatic dispersion and noise. Due to nonlinearity, the signal propagating through the fiber interacts with itself and with the noise generated from the inline amplifiers. LÄS MER

    Sammanfattning : Information technology evidence consists of a mix of representations of various applications of digital electronic equipment, and can be brought to the fore in all contexts that result in legal decisions. The occurrence of such evidence in legal proceedings, and other legal decision-making, is a phenomenon previously not researched within legal science in Sweden. LÄS MER

  4. 14. Designing for Usable Privacy and Transparency in Digital Transactions

    Författare :Julio Angulo; John Sören Pettersson; Simone Fischer-Hübner; Erik Wästlund; Joachim Meyer; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Usable privacy; usable transparency; usability; user experience; mental models; mobile devices; digital transactions; e-commerce; user interfaces; Information Systems; Informatik; Computer Science; Datavetenskap;

    Sammanfattning : People engage with multiple online services and carry out a range of different digital transactions with these services. Registering an account, sharing content in social networks, or requesting products or services online are a few examples of such digital transactions. LÄS MER

  5. 15. Superconductor Digital Signal Processor

    Författare :Irina Kataeva; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rapid Single Flux Quantum logic RSFQ ; multiuser detector; VHDL; Multiply-Accumulate Unit; Successive Interference Canceller;

    Sammanfattning : Superconductor digital technology based on Rapid Single Flux Quantum logic (RSFQ) offers more than 50 times gain in speed and more than 100 reduction in power consumption over mainstream CMOS devices. However, the necessity of cooling down to 4 K and modest degree of integration density currently available mean that employing RSFQ is reasonable only for the tasks that are impossible or ineffective to implement in CMOS technology.
