  1. 1. Information Erasure: An Information-Flow Approach to Semantics and Enforcement

    Detta är en avhandling från Chalmers University of Technology

    Författare :Filippo Del Tedesco; Chalmers tekniska högskola.; Chalmers University of Technology.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Computer science; erasure; information flow; security; erasure policies; enforcement; Python;

    Sammanfattning : Many modern online services require sensitive data to complete their tasks. For this reason, guaranteeing security policies in such services is a major concern. The traditional (and well studied) aspects of security, namely confidentiality, integrity, and availability of data, capture many but not all desirable policies involving sensitive-data. LÄS MER

  2. 2. An Information Flow Approach to Fault-Tolerant Security and Information Erasure

    Detta är en avhandling från Chalmers University of Technology

    Författare :Filippo Del Tedesco; Chalmers tekniska högskola.; Chalmers University of Technology.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information flow security; Information Erasure; Fault Tolerance;

    Sammanfattning : Sensitive information is a crucial asset for both individuals and companies. Since it is processed in a largely automated way, it is important that the computational infrastructures are equipped with methods for reasoning about and enforcing security policies. Information flow security has been proposed for this purpose in many contexts. LÄS MER

  3. 3. Coding Speech for Packet Networks

    Detta är en avhandling från Chalmers University of Technology

    Författare :Jonas Lindblom; Chalmers tekniska högskola.; Chalmers University of Technology.; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Informationsteknik; Information technology; speech coding; voice over IP; frame erasure; packet loss concealment; Gaussian mixture modeling; bounded support; sinusoidal modeling; harmonic modeling; vector quantization; variable dimension;

    Sammanfattning : The topic of this thesis is speech coding for packet networks. Problems related to the use of packet networks for voice communication are addressed. Real-time voice communication is for example very delay sensitive; if the total end-to-end delay in a telephone session grows large, it is perceived as annoying. LÄS MER

  5. 5. Learning not to fear : extinction, erasure, and the recovery of fear memories

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Clinical Neuroscience

    Författare :Armita Golkar; Karolinska Institutet.; Karolinska Institutet.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Much of the progress in understanding the mechanisms underlying the formation and persistence of fear memories comes from studies of Pavlovian conditioning and extinction. Recently, considerable interest has been turn to strategies that facilitate the development and persistence of extinction. LÄS MER
