1. 1. Consequences of alternative forest management in riparian buffer zones : a GIS analysis

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Elijah Ourth; [2023]
   Keywords : Riparian buffer zones; Continuous cover forestry; CCF; Hyggesfritt; Geographical information system; Ditch network maintenance; Ditch; Stream; Natural channel;

   Abstract : With increasing pressure from policymakers and the general public to conduct alternative forest management throughout the European Union (EU), Sweden needs to find ways to best prioritize the implementation of this alternative management. Alternative management is a term used to describe alternative management methods to clear-cut rotation forestry and can include silvicultural methods such as continuous cover forestry, management increasing proportion tree diversity and presence of broadleaves, and extended rotation lengths.

3. 2. Turbulent Boundary Layers Modelling with Deep Operator Networks

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Yu-Cheng Lu; [2023]
   Keywords : Turbulent Boundary Layers; Pressure Gradient; Composite Profiles; Deep Operator Networks; Sensitivity Analysis Nyckelord på svenska;

   Abstract : This thesis project aims to advance the modelling of pressure gradient turbulent boundary layers (PG TBLs) and offer new insights into TBLs modelling. Previous analytical studies have explored various mathematical models, but this research introduces an extended unstacked Deep Operator Networks (DeepONets) architecture with double outputs and five branch parameters.

4. 3. Adjoint optimization of a liquid-cooled heat sink

   University essay from KTH/Teknisk mekanik

   Author : Roven Pinto; [2023]
   Keywords : Adjoint method; topology optimization; porosity; OpenFOAM;

   Abstract : Improving the design of flow channels in a liquid-cooled heat sink is critical for boosting the capabilities of electronic components as well as reducing energy usage by the pump. This work explores the use of topology optimization to minimize the pressure difference across a heat sink and consequently, the energy used to supply the liquid. READ MORE

5. 4. ASSESING HISTORICAL (1926-1996) NEAR-SURFACE WIND SPEED VARIABILITY ACROSS SWEDEN

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Jessika Lönn; [2022-06-27]
   Keywords : Near-surface wind speed; teleconnection patterns; Sweden; stilling; reversal;

   Abstract : Homogenized near-surface wind speed (NSWS) series of 7 stations from rescued observational journals have been analyzed for the 70-years time-period 1926-1996 to investigate past changes and variations across Sweden. During the whole period, there has been a statistically significant (at p < 0.05) decreasing trend of -0.11 m s-1 decades-1. READ MORE

6. 5. Modelling Gas Flow Behaviour in Gas Atomizer

   University essay from KTH/Materialvetenskap

   Author : Aravind Senan Vasanthasenan Reji; [2022]
   Keywords : Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

   Abstract : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.
