1. 1. Mouthfeel Assessment of Tetra Pak Paper Straws: Exploring the Correlation between Instrumental Measurements and Sensory Evaluation

   University essay from Lunds universitet/Förpackningslogistik

   Author : Natchaya Hanprerakriengkrai; [2023]
   Keywords : mouthfeel; paper straws; correlations; instrumental measurement; sensory evaluation; Technology and Engineering;

   Abstract : The implementation of the Single-Use Plastics Directive has gained significant attention due to the detrimental impacts of plastic pollution, leading to the transition from plastic straws to paper straws for Tetra Pak’s portion-size carton packages. However, the acceptance of paper straws could be hindered by negative mouthfeel perceptions, which customers find the difficulties to accurately describe them. READ MORE

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Vyshak Mohandas; Sreekuttan Thazhathe Kalathil; [2023]
   Keywords : Gear; FZG-test; Electric vehicles; Mechano-Chemical Surface Treatment; Efficiency; Surface Roughness.; Gear; FZG-test; Elfordon; Mekanisk-kemisk ytbehandling; Effektivitet; Ytsträvhet.;

   Abstract : This thesis presents an experimental research study aimed at identifying the optimal mechano-chemical surface treatment for powder metallurgy gears utilized in electric vehicles (EVs). The primary objective of the study is to determine the most effective surface treatment method in terms of enhancing gear transmission efficiency. READ MORE

4. 3. Shallow Water : A comparison between hydraulic measurements and numerical models

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Dan Nilsson; [2023]
   Keywords : CFD; Surface Roughness; Manning coefficient; Hydropower;

   Abstract : In the near future hydropower will be used to regulate intermittent energy sources, shallow water ways can then occur in close proximity to the power plants, where the bottom often consists of stones in a similar length scale as the water depth. The idea of this project, which has been initiated by Vattenfall R\&D, is to compare experimental measurements in a laboratory environment with numerical simulations with CFD, this to find a way to represent roughness structures where there is low relative submergence.

5. 4. Turbine Performance Analysis in Wake and Wake-Free Conditions Using Nacelle Mounted Lidar at a Wind Farm in Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Izabela Fijołek; [2022]
   Keywords : Sweden; wind power; onshore; lidar; wake effect; performance analysis; power curve;

   Abstract : The need for optimizing wind farms’ production and maximizing the profitability of projects necessitates power performance analysis. Nowadays, the use of remote sensing devices for this purpose becomes more and more popular due to many advantages this technology has over traditional met masts. READ MORE

6. 5. Manning’s roughness coefficient in small scale nature-like fish passages

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Aleksander Jaworowski; [2022]
   Keywords : Manning’s coefficient; flow measurement; fish passage; fish migration; roughness coefficient; Technology and Engineering;

   Abstract : Fishway construction remains a crucial measure in environmental adaption of flow barriers. A well-functioning fishway should be able to pass all naturally occurring species of fish and other aquatic fauna. READ MORE
