1. 11. Gate Drive Design for SiC MOSFET Device Characterization : Investigation into the impact of the gate inductance and resistance on the switching behaviour of SiC Power MOSFETs

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

   Author : Elochukwu Mbah; [2023]
   Keywords : Silicon Carbide Power MOSFET; Gate Inductance; Gate Resistance; Miller Period; dv dt and di dt transients; Double Pulse Test; Kiselkarbid Power MOSFET; Gateinduktans; Gate Resistance; Millerperioden; dv dt och di dt transienter; Dubbelpulstest.;

   Abstract : Silicon Carbide as a wide-bandgap semiconductor has several physical and electrical advantages over Silicon for high voltage and high frequency applications. SiC as a MOSFET device has a lot of great characteristics like lower on-resistance and low input capacitances. READ MORE

3. 12. Structural responses due to underwater detonations : Validation of explosion modelling methods using LS-DYNA

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Gustav Blomgren; Ebba Carlsson; [2023]
   Keywords : Underwater explosion; UNDEX; detonation; fluid structure interaction; FSI; SSA; S-ALE; shock-wave; explosive; PETN; explosive modelling; Sub-Sea Analysis; Structured ALE; Arbitrary Lagrangian Euler; Multi Material Arbitrary Lagrangian Euler; MMALE; LS-DYNA;

   Abstract : Modelling the full event of an underwater explosion (UNDEX) is complex and requires advanced modelling methods in order to achieve accurate responses. The process of an UNDEX includes a series of events that has to be considered. READ MORE

4. 13. Weight status and psychosomatic complaints in Swedish adolescent boys and girls: examining the buffering role of family support.

   University essay from Stockholms universitet/Institutionen för folkhälsovetenskap

   Author : Jasmin Venäläinen; [2023]
   Keywords : Weight status; overweight; obesity; psychosomatic complaints; family support; adolescents; HBSC;

   Abstract : Introduction: Psychosomatic complaints have increased among adolescents in recent decades, as well as overweight and obesity rates, which have become a public health issue. The associations between weight status and psychosomatic complaints are not clear, therefore further research is needed. READ MORE

5. 14. Design and evaluation of a novel Transillumination SFDI system for quantitative assessment of tissuesections for rapid, label-free cancer margin detection

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Merel Younan; [2023]
   Keywords : SFDI; transillumination SFDI system; tissue-conserving surgeries; thin layers; tissue analysis; skin cancer;

   Abstract : This study investigates the potential of Spatial Frequency Domain Imaging (SFDI) as a non-invasive imaging technique for tissue analysis in the context of Mohs surgery, a standard procedure for skin cancer removal with margin control. The current practice of performing multiple histopathologic sections during the procedure is time-consuming and labor-intensive. READ MORE

6. 15. Modelling and Optimisation of Relativistic Magnetron with Transparent Cathode : Applications for High-Power Microwaves

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : David Sawert; [2023]
   Keywords : Relativistic Magnetron; RM; High-Power Microwaves; HPM; Particle-in-Cell; PIC; MAGIC3D; TE11;

   Abstract : This thesis aimed to investigate the relativistic magnetron (RM), which is a high-power microwave (HPM) source. Since the RM can generate high-intensity microwave radiation, it can be used as a pulsed electromagnetic weapon to target electronic systems in different objects, such as drones, missiles, or vehicles.
