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

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

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

   Abstract : 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. READ MORE

3. 2. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Joel Fransson Forsberg; [2023]
   Keywords : Vibrations; Formica ants; Vibrometer; Vibrational signals; Imidacloprid; Before-After-Control-Impact;

   Abstract : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. READ MORE

4. 3. Detection of voids in welded joints using ultrasonic inspection : Quality control of welded joints in copper canisters for purpose of permanent storage of used nuclear waste

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Bakhtiar Afzalan; [2021]
   Keywords : Ultrasonic inspection; Nuclear waste; Nuclear waste storage; welded joints;

   Abstract : This thesis was done i cooperation with SKB Clab in Oskarshamn and studies use of sonic waves for detecting voids and irregularities in the weld joints of copper capsules used for long term storage of radioactive waste. Since these could pose material failure and thereby risk radioactive contamination of ground water it is very important to find means of quality control before storage. READ MORE

5. 4. Investigation into the pedagogical value of demonstrating deliberate design deficiencies in PCB design instruction

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Björn Sunedal; [2021]
   Keywords : PCB design; Interactive Lecture Demonstration; PODS; pedagogy; PCB-konstruktion; Interaktiv föreläsningsdemonstration; PODS; pedagogik;

   Abstract : Universities and other higher education institutions have been struggling with high levels of student dropouts and poor graduation rates for a long time. As a result, there has been an interest in modifying traditional teaching techniques and implementing new ones to improve student learning outcomes. READ MORE

6. 5. Dynamic analyses of hollow core slabs : Experimental and numerical analyses of an existing floor

   University essay from KTH/Bro- och stålbyggnad

   Author : Markus Hansell; Panagiotis Tamtakos; [2020]
   Keywords : Hollow core slab; Structural dynamics; Signal analysis; Mode shape; Frequency response function; Complex mode; FE-model; Håldäcksbjälklag; Strukturdynamik; Signalanalys; Modform; Frekvenssvar; Komplex mod; FE-modellering.;

   Abstract : For intermediate floors in residential and office buildings, as well as in parking garages and malls, there is a wide use of hollow core concrete slabs in Sweden today. Hollow core slabs are precast and prestressed concrete elements with cylindrical-shaped voids extending along the length of the slab. READ MORE
