1. 6. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Franz Wikner; [2024]
   Nyckelord :Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

   Sammanfattning : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

3. 7. EFFEKTER PÅ UPPSTRÖMSSTABILITETEN I FYLLNINGSDAMMAR : Ändrade porvattentryck till följd av cykliska magasinsnivåer

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Emma Widén; [2024]
   Nyckelord :Vattenfluktuationer; Släntstabilitet; Porvattentryck; Tolererat fel; Finita elementmetoden;

   Sammanfattning : Hydropower is one of the few energy sources with the ability to store a resource and thus regulate electricity production. When the water level in a reservoir changes, this affects the pore water pressures in the dam. LÄS MER

4. 8. Estimating Diffusion Tensor Distributions With Neural Networks

   Master-uppsats, Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

   Författare :Rimaz Nismi; [2024]
   Nyckelord :Diffusion; Magnetic Resonance Imaging; MRI; Neural Networks; Optimal transport; Earth mover s distance; Sinkhorn distance;

   Sammanfattning : Magnetic Resonance Imaging (MRI) is an essential healthcare technology, with diffusion MRI being a specialized technique. Diffusion MRI exploits the inherent diffusion of water molecules within the human body to produce a high-resolution tissue image. An MRI image contains information about a 3D volume in space, composed of 3D units called voxels. LÄS MER

5. 9. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

   Författare :Fredrik Malmström; [2024]
   Nyckelord :;

   Sammanfattning : The thesis proposes to model the flow of gases in a room by solving the incompressible Navier-Stokes equations in three dimensions. The transportationof scalars such as temperature and concentration of CO2 is modeled by solving the advection-diffusion equation, and the effects of temperature on thevelocity is accounted for by employing the Boussinesq approximation.

7. 10. FE-Modelling of Composite Girder tests

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Holger Berggren; Bergstedt Ola; [2024]
   Nyckelord :shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

   Sammanfattning : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. LÄS MER
