1. Finite-Element Analysis of Cryogenic Pressure Vessels Under Blast Loading
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : The behavior of cryogenic double-walled pressure vessels, such as thoseused in space launch vehicle infrastructure, under blast loading is a somewhatunderstudied topic. This is of interest due its implications on, among otherthings, launch site design and safety in the event of a launch vehicle failure. LÄS MER
2. Undersökning och täthetsmätning av små mekaniska komponenter.Leakage testing and analysis on small mechanical devices
Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : The work was conducted at Saab Dynamics AB in Karlskoga, and the focus was to investigate and evaluate available methods for leak detection of small mechanical components, such as Electro-Explosive Devices (EEDs) and fuzes in warheads and using these methods to investigate whether they work for this purpose. At the start of the project, the problem was that these mechanical components were exposed to contamination, such as moisture and dust but also TNT exudate, plasticizers, gunpowder residues, etc. LÄS MER
3. Transmedia Narrative Transportation och hur influerare verkar på sociala plattformar : En netnografisk studie på hur individuella influerares förhållningssätt gentemot sociala plattformar kan ses med ett teoretiskt förhållningssätt
Kandidat-uppsats, Umeå universitet/Institutionen för informatikSammanfattning : The aim of this study is to compare how transmedia narrative transportation theory (TNT) can be used on social plattform by influencers to how they are doing it. Social platforms are a relatively new phenomenon that is constant evolving both technical and how it´s used by the society. LÄS MER
4. An Arbitrary Lagrangian-Eulerian Finite Element Method for Shock Wave Propagation: Validating Simulations of Underwater Explosions
Master-uppsats, KTH/Numerisk analys, NASammanfattning : Underwater explosions are often modeled with Arbitrary Lagrangian-Eulerian (ALE) Finite Element Methods. The objective of this thesis is to validate the simulation method, with respect to the propagating shock wave. A two-dimensional axisymmetric model of a spherical TNT charge submerged in water is simulated using LS-DYNA. LÄS MER
5. Spårmängdsanalys av explosivämnen
Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : There is an alarming increase of explosions with devastating consequences, the ultimate being loss of life. Furthermore, these kinds of substances have a toxic effect on animals, nature and humans if they are incorrectly disposed. LÄS MER
