  1. 1. Physical Layer Security for MIMOTransmission of Short PacketCommunications

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Varun Duvva; Bharath Reddy Anugu; [2024]
    Nyckelord :Physical Layer Security; Multiple-Input Multiple-Output; Short Packet communication; Maximum Ratio Combining; Maximum Ratio Transmission; and Beamforming;

    Sammanfattning : This thesis explores the practical application of Physical Layer Security (PLS) inMultiple-Input Multiple-Output (MIMO) systems, particularly focusing on ShortPacket Communication (SPC). The aim is to enhance the security of wireless com-munications against eavesdropping threats. LÄS MER

  3. 2. Implicit Message Integrity Provision : In Heterogeneous Vehicular Systems

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Paul Molloy; [2023]
    Nyckelord :Privacy; Code Generation; Vehicle-to-infrastructure; Vehicular ad hoc Networks; Standardization; Remote Procedure Calls; Safety; Integritet; Kodgenerering; Fordon-till-infrastruktur; Ad hoc-nät för Fordon; Standardisering; Samtal om fjärrprocedur; Säkerhet;

    Sammanfattning : Vehicles on the road today are complex multi-node computer networks. Security has always been a critical issue in the automotive computing industry. It is becoming even more crucial with the advent of autonomous vehicles and driver assistant technology. There is potential for attackers to control vehicles maliciously. LÄS MER

  4. 3. Methods and Purposes of Aerodynamic Correlation in Formula Student

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Alix Le Bastard; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis investigates how methods of aerodynamic validation can assist a formula student team in designing their aerodynamic package. When de- signing their aerodynamic components, formula student team mostly rely on CFD software simulations, but there is no guarantee that the simulations de- pict properly the physical behaviour of the airflow around the car.

  5. 4. Visualizing Zones : Defining the Notion of Zones in Physical Access Control for Security Management System

    Kandidat-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

    Författare :Joanne Ju; [2023]
    Nyckelord :physical access control; security; zone visualisation; abstract representation; visual communication; space and place; human perception; workplace study; human-computer interaction HCI ; Computer Supported Cooperative Work CSCW ; research through design; interaction design;

    Sammanfattning : In the domain of access control, the notion of zone is still ambiguous. The zone demands clearer contextualization that resonates with the security operators in their workplace. LÄS MER

  7. 5. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

    Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Shivang Parmar; [2023]
    Nyckelord :Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

    Sammanfattning : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. LÄS MER
