  1. 1. On Adapting Data Collection to Intrusion Detection

    Författare :Ulf Larson; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; attack manifestation; data reduction; in-vehicle network; attack analysis; adaptation; intrusion detection; computer security; data collection; forensic investigation;

    Sammanfattning : Intrusion detection systems (IDSs) are capable of detecting both suspicious insider activity and attacks from external penetrators. They can also detect both known and previously unknown attacks. These capabilities make them valuableassets in the protection of computer systems and networks. LÄS MER

  2. 2. Never Heard Before: A Musical Exploration of Organ Voicing

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :João Segurado; Göteborgs universitet.; Gothenburg University.; [2015]
    Nyckelord :HUMANIORA; HUMANITIES; voicing; voicing; sound; listening; pipe; organ; tone; musical composition; musical performance; experimental; collaboration; artistic research; ethnography; musique concrète; transient; attack; steady-state; harmonic spectrum; languid; toe-hole; mouth; flue; reed; Studio Acusticum; Gerald Woehl; Piteå;

    Sammanfattning : This study describes the role of organ sounds in musical performance and exa- mines the visions and artistic perspectives of the voicer, who creates the sounds, and the organist, who uses them in performance. Organ pipe sounds are shaped in a process of gradual transformation called voicing, to suit the practice of musical performance, and they influence that practice in significant ways. LÄS MER

  3. 3. On Some Symmetric Lightweight Cryptographic Designs

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Martin Ågren; Lunds universitet.; Lund University.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight cryptography; integrity; authentication; symmetric cryptography; stream ciphers; block ciphers; Grain-128a; BEAN; KTANTAN; textsc{PRINTcipher}; FCSR combiner; related-key attack; linear cryptanalysis; linear correlations; invariant subspace attack.;

    Sammanfattning : This dissertation presents cryptanalysis of several symmetric lightweight primitives, both stream ciphers and block ciphers. Further, some aspects of authentication in combination with a keystream generator is investigated, and a new member of the Grain family of stream ciphers, Grain-128a, with built-in support for authentication is presented.

  4. 4. Symptomatic Carotid Stenosis - optimal timing of surgical treatment

    Detta är en avhandling från Göteborg : University of Gothenburg. Sahlgrenska Academy, Institute of Medicine

    Författare :Sofia Strömberg; Göteborgs universitet.; Gothenburg University.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carotid endarterectomy; carotid artery stenosis; stroke; transient ischemic attack; ocular transient ischemic attack;

    Sammanfattning : Abstract In patients with symptomatic carotid artery stenosis is convincing evidence that carotid endarterectomy (CEA) confers maximum benefit if performed within 14 days from index event. Patients with TIA or minor stroke have an increased risk of early recurrent stroke in the first weeks after the index event, then declining over months. LÄS MER

  5. 5. Model based aircraft design : high angle of attack aerodynamics and weight estimation methods

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Christopher Jouannet; Linköpings universitet.; Linköpings universitet.; [2005]

    Sammanfattning : This thesis addresses modelling of high angle of attack aerodynamic characteristics and weight estimation for highly maneuverable aircraft during conceptual design. In order to allow configuration selection with sufficient confidence, especially with unconventional configurations, high angle of attack aerodynamic prediction and weight estimations methods need to be improved.
