  1. 11. Software Defined VNA : Measure Coupling Between Elements in an Antenna Array

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Alexander Söderlund; [2023]
    Nyckelord :VNA; Vector Network Analyser; SDR; KrakenSDR; S-parameter; Antenna Coupling;

    Sammanfattning : With improvements in hardware of antenna receivers, fully digital arrays have been made possible to use in real time systems. These systems have a greater complexity, with the advantage of more dynamic system design since the use of the communication system can be changed with only a software change. LÄS MER

  3. 12. Utveckling av driftstöd för planering av fjärrkyla : En explorativ studie om utvecklingen av ett optimeringsbaserat driftplaneringsverktyg för fjärrkylanätet City i Linköping, Sverige

    Master-uppsats, Linköpings universitet/Energisystem

    Författare :Christian Haapanen; Louise Hedenskog; [2023]
    Nyckelord :District cooling; MILP; UC problem; Optimization; Operational plan; Smart energy systems; Fjärrkyla; MILP; UC problem; Optimering; Driftplanering; Smarta energisystem;

    Sammanfattning : The average global temperature is rising due to climate change. This leads to an increase in cooling demand along with higher usage of electricity to operate cooling processes. One way to decrease the electricity usage is to introduce absorption cooling which uses heat instead of electricity as its main source of power. LÄS MER

  4. 13. Adjoint optimization of a liquid-cooled heat sink

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Roven Pinto; [2023]
    Nyckelord :Adjoint method; topology optimization; porosity; OpenFOAM;

    Sammanfattning : Improving the design of flow channels in a liquid-cooled heat sink is critical for boosting the capabilities of electronic components as well as reducing energy usage by the pump. This work explores the use of topology optimization to minimize the pressure difference across a heat sink and consequently, the energy used to supply the liquid. LÄS MER

  5. 14. Securing SDN Data Plane:Investigating the effects of IP SpoofingAttacks on SDN Switches and its Mitigation : Simulation of IP spoofing using Mininet

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :SHIVAKUMAR YADAV JABBU; ANIRUDH SAI MADIRAJU; [2023]
    Nyckelord :Software Defined Networking; IP Spoofing; Flooding; DDoS Attacks; Data Plane; Mininet;

    Sammanfattning : Background:Software-Defined Networking (SDN) represents a network architecture that offers a separate control and data layer, facilitating its rapid deployment and utilization for diverse purposes. However, despite its ease of implementation, SDN is susceptible to numerous security attacks, primarily stemming from its centralized nature. LÄS MER

  7. 15. Optimizing Relay Placement for Scalable Secure VPLS Networks using Facility Location Modeling

    Master-uppsats, Linköpings universitet/Databas och informationsteknik

    Författare :Xi Tan; [2023]
    Nyckelord :VPLS; HIP; CFLP; SDN;

    Sammanfattning : Virtual Private LAN Service (VPLS) networks have emerged as a popular solution for providing scalable and efficient Layer 2 connectivity across wide-area networks. However, designing secure and scalable VPLS networks presents significant challenges. LÄS MER
