1. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room
University essay from Uppsala universitet/Avdelningen för beräkningsvetenskapAbstract : 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.

2. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. READ MORE

3. Accumulation of 63Ni, 106Ru and 125Sb in phytoplankton
University essay fromAbstract : Background: Nuclear Power Plants (NPPs) release small amounts of radionuclides which contribute with a low radiation dose to the environment as well as humans and animals. In this context, marine ecosystems are critical, since most NPPs in Sweden are located by the sea. READ MORE

4. Deanonymizing Onion Services byIntroducing Packet Delay
University essay from Blekinge Tekniska HögskolaAbstract : Background. Onion services facilitate two-way communication over the Tor net-work without letting either party know the other address or location. Many different techniques to break that anonymizing have come forth, but most of them have only been on paper. Some have been tested but then only on a separate network and not on the live Tor network. READ MORE

5. Hydrogen Fuel Cell Lifetime Simulation in Marine Applications
University essay from KTH/Kraft- och värmeteknologiAbstract : Maritime transportation emits about 3% of global greenhouse gas, International Maritime Organization (IMO) aims to reduce shipping’s emissions by 50% with respect to 2008 levels. Proton exchange membrane fuel cells (PEMFCs) are considered among the most promising clean technologies for decarbonizing the maritime sector. READ MORE
