1. 1. The Drivers of Decoupling: The Influence of Political factors on CO2 Emissions using a two-way fixed effect approach

   University essay from Göteborgs universitet/Graduate School

   Author : Emilia Akbary; Daniella Söderling; [2023-06-29]
   Keywords : Fixed effects; Political indicators; Carbon emissions; Environmental Kuznets Curve; Decoupling; Sustainable Development;

   Abstract : The fight against climate change and the subsequent discussions about sustainable growth have been ongoing for decades. While multiple countries have successfully achieved sustainable growth, which is described as decoupling in the literature, it is still unanswered which factors are the key driving forces. READ MORE

3. 2. Drivers of sea level variability using neural networks

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Linn Carlstedt; [2023-05-10]
   Keywords : ;

   Abstract : Understanding the forcing of regional sea level variability is crucial as many people all over the world live along the coasts and are endangered by extreme sea levels and the global sea level rise. The adding of fresh water into the oceans due to melting of the Earth’s land ice together with thermosteric changes has led to a rise of the global mean sea level with an accelerating rate during the twentieth century.

4. 3. Neural Network-based Anomaly Detection Models and Interpretability Methods for Multivariate Time Series Data

   University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

   Author : Deepthy Prasad; Swathi Hampapura Sripada; [2023]
   Keywords : multivariate - time series; anomaly detection; neural networks; autoencoders; interpretability; counterfactuals;

   Abstract : Anomaly detection plays a crucial role in various domains, such as transportation, cybersecurity, and industrial monitoring, where the timely identification of unusual patterns or outliers is of utmost importance. Traditional statistical techniques have limitations in handling complex and highdimensional data, which motivates the use of deep learning approaches. READ MORE

5. 4. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Tanmmay Rout; [2023]
   Keywords : Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

   Abstract : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

6. 5. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Zhenyu Li; [2023]
   Keywords : mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

   Abstract : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. READ MORE
