  1. 1. Supporting Scientific Collaboration through Workflows and Provenance

    Författare :Tommy Ellqvist; Nahid Shahmehri; Paolo Missier; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Scientific collaboration; workflow; provenance; search engine; query language; data integration; Computer science; Datalogi;

    Sammanfattning : Science is changing. Computers, fast communication, and  new technologies have created new ways of conducting research.  For  instance, researchers from different disciplines are processing and  analyzing scientific data that is increasing at an exponential rate. LÄS MER

  2. 2. Tectonic Evolution of Taimyr in the Late Paleozoic to Mesozoic from Provenance and Thermochronological Evidence

    Författare :Xiaojing Zhang; Victoria Pease; Arild Andresen; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Taimyr; sandstones; provenance; heavy mineral analysis; detrital zircon; apatite fission track; tectonic setting; uplift; Geology; geologi;

    Sammanfattning : The Taimyr Peninsula is a key element in the circum-Arctic region and represents thenorthern margin of the Siberian Craton. The Taimyr Peninsula is a late Paleozoic fold andthrust belt and preserves late Paleozoic through Mesozoic siliciclastic sedimentarysuccessions and providing an ideal location to investigate the Paleozoic to Mesozoictectonic evolution associated with the Uralian orogeny, the Siberian Trap magmatism andopening of Amerasia Basin within a circum-Arctic framework.

  3. 3. Understanding Crustal Volatiles : Provenance,  Processes and Implications

    Författare :Lara S. Blythe; Valentin Troll; Ralf Gertisser; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; crustal volatiles; helium; carbon; volcanic gases and fluids; xeno-pumice; magma-carbonate interaction; upper crustal contamination;

    Sammanfattning : Knowledge of the provenance of crustal volatiles and the processes by which they are released is extremely important for the dynamics of magmatic systems. Presented here are the results of multiple investigations, which aim to understand magmatic volatile contamination from contrasting but complementary perspectives. LÄS MER

  4. 4. Deterministic, Explainable and Resource-Efficient Stream Processing for Cyber-Physical Systems

    Författare :Dimitrios Palyvos-Giannas; Chalmers University of Technology; []

    Sammanfattning : We are undeniably living in the era of big data , where people and machines generate information at an unprecedented rate. While processing such data can provide immense value, it can prove especially challenging because of the data's Volume, Variety and Velocity . LÄS MER

  5. 5. Privacy-aware Use of Accountability Evidence

    Författare :Jenni Reuben; Simone Fischer-Hübner; Siani Pearson; Karlstads universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Privacy; accountability; audit; evidence; system traces; provenance; access control; privacy compliance; security; Computer Science; Datavetenskap;

    Sammanfattning : This thesis deals with the evidence that enable accountability, the privacy risks involved in using them and a privacy-aware solution to the problem of unauthorized evidence disclosure. Legal means to protect privacy of an individual is anchored on the data protection perspective i.e., on the responsible collection and use of personal data.
