  1. 1. Interscale transport of Reynolds stresses in wall-bounded flows

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Författare :Gioele Ferrante; Andres Morfin; [2019]
    Nyckelord :Reynolds Stress; Zero-Pressure Gradient Turbulent Boundary Layer; Turbulent Couette Flow; Inverse Interscale Transport; Energy Cascase; Wall-bounded Flows; Direct Numerical Simulation; Large Eddy Simulation.;

    Sammanfattning : Couette, pipe, channel, and zero-pressure gradient (ZPG) turbulent boundary layer (TBL) flows have classically been considered as canonical wall-bounded turbulent flows since their near-wall behavior is generally considered to be universal, i.e. invariant of the flow case and the Reynolds number.

  2. 2. DNS Performance : A study of free, public and popular DNS servers in 2019

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap; Linköpings universitet/Institutionen för datavetenskap

    Författare :Felix Zedén Yverås; Filip Ström; [2019]
    Nyckelord :DNS; DNS Performance; Response Time;

    Sammanfattning : The Domain Name System (DNS) is an integral part of making the internet a more human-friendly place. However, it comes with the cost of an added abstraction layer that introduces extra latency in many aspects of the modern computing experience - a great selling point for many DNS services. LÄS MER

  3. 3. Hantering av nätverkscache i DNS

    Kandidat-uppsats, Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Författare :Hans Lindqvist; [2019]
    Nyckelord :Caching name server; DNS; Internet of Things; Ipv6; Unbound; PowerDNS Recursor; Cachande namnserver; DNS; Sakernas Internet; Ipv6; Unbound; PowerDNS Recursor;

    Sammanfattning : The Domain Name System, DNS, is a fundamental part in the usability of the Internet, but its caching function is challenged by the increase of address size, number of addresses and automation. Meanwhile, there are limits in the memory capacity of certain devices at the Internet’s edge towards the Internet of Things. LÄS MER

  4. 4. DETECTION of INFRASTRUCTURE ANOMALIES in BUILD LOGS USING MACHINE LEARNINGText classification on Continous Integration log files.

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Didrik Lindqvist; [2019]
    Nyckelord :;

    Sammanfattning : Continuous integration is a practice where software developers integrate their code to a bigger codebase multiple times per day. Before the integration, the code is built and tested by e.g open source build tools such as Jenkins, and the information produced during this process is stored in a log file. LÄS MER

  5. 5. Enabling high-fidelity measurements of turbulent boundary layer flow over wing sections in the MTL wind tunnel.

    Master-uppsats, KTH/Mekanik

    Författare :Fermin Mallor; [2019]
    Nyckelord :Fluid mechanics; aerodynamics; turbulence; RANS; wind-tunnel experiments; insert design; Strömningsmekanik; aerodynamik; turbulens; RANS; vindtunnel experiment; inlaga designen;

    Sammanfattning : A reinforced fiber-glass model of a NACA 4412 wing profile is designed and set-up in the Minimum Turbulence Level (MTL) wind tunnel facility at KTH. The model has 65 pressure taps orifices, and the set-up includes two mounting panels designed to allow for particle image velocimetry (PIV) and hot wire anemometry (HWA) measurements of the boundary layer (to be performed in a future campaign).
