  1. 11. Microresonator combs for coherent optical communications

    Författare :Attila Fülöp; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber-optic communication; nonlinear optics; integrated optics devices; four-wave mixing; microresonators;

    Sammanfattning : This thesis covers the study of microresonator-based optical frequency combs for use in coherent optical communication links. Current links typically utilize several free-running lasers to achieve wavelength-division multiplexing (WDM). LÄS MER

  3. 12. Smuggle, Frame, Shoot : Illicit Media Practices and Visual Insurgency from Lebanese Incarceration

    Författare :Chafic T. Najem; Kari Andén-Papadopoulos; Malin Wahlberg; Anne Kaun; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; media studies; visual culture; media practice; media witnessing; digital activism; vulnerability; prison practices; prison representations; prison testimonies; medie- och kommunikationsvetenskap; Media and Communication Studies;

    Sammanfattning : This research explores prisoners’ illicit use of digital-media technology during their incarceration in Lebanon. Prisoners smuggle cellphones and access internet and telecommunication connection to produce and mediate videos, images, and voice recordings documenting quotidian experiences of imprisonment, violent events, and the COVID-19 Pandemic inside the notorious and overcrowded Roumieh Central Prison.

  4. 13. Library Communication Among Programmers Worldwide

    Författare :Erik Berglund; Henrik Eriksson; Sture Hägglund; Kjell Ohlsson; Kristian Sandahl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; software development; library-based programming; library communication; hypertext documentation; Open-source; bug handling; object-oriented programming; Computer science; Datavetenskap;

    Sammanfattning : Programmers worldwide share components and jointly develop components on a global scale in contemporary software development. An important aspect of such library-based programming is the need for technical communication with regard to libraries – library communication. LÄS MER

  5. 14. Secure and Privacy-Aware Data Collection in Wireless Sensor Networks

    Författare :Ioana Rodhe; Christian Rohner; Per Gunningberg; Roberto Di Pietro; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secure Data Collection; Key Distribution; Location Privacy; Quality of Information; Wireless Sensor Networks; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : A wireless sensor network is a collection of numerous sensors distributed on an area of interest to collect and process data from the environment. One particular threat in wireless sensor networks is node compromise attacks, that is, attacks where the adversary gets physical access to a node and to the programs and keying material stored on it.
