1. 1. EV battery temperature estimation : Designing a model for minimal temperature of high-voltage battery in a BEV

   University essay from Mittuniversitetet/Institutionen för data- och elektroteknik (2023-)

   Author : Björn Arvidsson; [2023]
   Keywords : BEV; temperature estimation; lowpass filter; BEV; lågpassfilter; temperaturestimering;

   Abstract : Fordonsindustrin är inne i ett skifte, där förbränningsmotorer (ICE) bör-jar fasas ut och det satsas mer på eldrift med hjälp av batterier (BEV).  I detta arbete, som efterfrågades av Volvo Cars, utvecklades en matema-tisk modell som uppskattar den lägsta temperaturen i en elbils högspän-ningsbatteri.

3. 2. Estimating Ambient Temperature using Internal Sensors and Thermal Modelling in Mobile Phones

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Isak Evaldsson; Henrik Paulcén; [2023]
   Keywords : Technology and Engineering;

   Abstract : This thesis studies the possibility of estimating the ambient temperature around a mobile phone using its internal temperature sensors. The thesis aims to develop and evaluate ambient temperature models that use internal temperature sensors within the device and, from a manufacturer’s perspective, investigate if the models for ambient temperature can be enhanced by tailoring them to the internals of specific devices.

4. 3. Dynamic Warning Signals and Time Lag Analysis for Seepage Prediction in Hydropower Dams : A Case Study of a Swedish Hydropower Plant

   University essay from Uppsala universitet/Datalogi

   Author : Lovisa Olsson; Julia Hellström; [2023]
   Keywords : hydropower; dam safety; dam monitoring; seepage; prediction models; data-driven methods; artificial intelligence; AI;  linear regression; Support Vector Regression; SVR; Long Short-Term Memory; LSTM;

   Abstract : Hydropower is an important energy source since it is fossil-free, renewable, and controllable. Characteristics that become especially important as the reliance on intermittent energy sources increases. However, the dams for the hydropower plants are also associated with large risks as a dam failure could have fatal consequences. READ MORE

5. 4. Fouling modelling in a UHT unit based on plant data.

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Thai Lam; [2023]
   Keywords : UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

   Abstract : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. READ MORE

6. 5. Efficiency of radial piston hydraulic motors

   University essay from Umeå universitet/Institutionen för fysik

   Author : Jennifer Eriksson; [2023]
   Keywords : Efficiency; Loss mechanics; MATLAB; Simulation model; Radial piston hydraulic motor;

   Abstract : In a world with high energy cost, the efficiency of motors becomes increasingly important. Thereby, the understanding of loss mechanics is of great significance and having accurate simulation models for the efficiency of motors is crucial. READ MORE
