1. 21. Development of grey-box models for simulating heating consumption in buildings : A study applying system identification methodology to a physics-based framework

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Zack Klockar; [2021]
   Keywords : System identification; heating; buildings; modelling; insulation; empirical modelling; ARX; OE; time-series; simulation; energy consumption; grey-box; black-box;

   Abstract : This study models the energy used for heating in buildings by applying system identification methodology. The model development is grounded in physics to provide guidance and interpretability when evaluated. Time-series of heating demand, outdoor temperature, indoor temperature and solar irradiation are considered for the modelling purpose. READ MORE

3. 22. Modeling wind-induced currents in lake Bolmen, Sweden, using TELEMAC 2D

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Prasanjaya Bandara Ekanayake; [2021]
   Keywords : Bolmen Lake; TELEMAC 2D; Wind induced currents; QGIS; Blue Kenue; Technology and Engineering;

   Abstract : Transport and material intermixing within lake systems have a significant impact on lake water quality. However, since researchers are primarily concerned with biological, environmental, and ecological aspects, physics and hydrodynamic behavior in lake water currents frequently receive less attention.

4. 23. Analysis of Forecasts for District Heat Production using Different Models for Seasonal Partitions

   University essay from Lunds universitet/Matematisk statistik

   Author : Leo Einarsson; [2021]
   Keywords : District heating; heat production; energy; time series; statistical bootstrap; prediction; regression; model based on season; Mathematics and Statistics;

   Abstract : District heating is a common means of space and hot water heating in Sweden. However, the demand for heating is not the same at all times. On a yearly basis more heat is required during winter, while next to none is needed in summer. READ MORE

5. 24. Modelling of water and material transport in River Storån to Lake Bolmen

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Imjal Sukupayo; [2021]
   Keywords : Brownification; Water Color; Dissolved Organic Matter; Discharge; hydraulic analysis; Tracer Analysis; Dispersion coefficient; Advection and Diffusion; Bolmen Lake; Storån River; Technology and Engineering; Earth and Environmental Sciences;

   Abstract : The change of color of water from yellow to brown termed as brownification process is mainly due to leaching of humus and iron concentrations. In recent years, this problem is increasing in lake Bolmen, a major source of drinking water in Skåne county, Sweden. READ MORE

6. 25. Inferring 3D trajectory from monocular data using deep learning

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

   Author : Victor Sellstedt; [2021]
   Keywords : Deep Learning; Monocular trajectory estimation; Time series prediction; Synthetic data; Djupinlärning; Inferens från monkulära sekvenser; Tidsserieanalys; Syntetisk data;

   Abstract : Trajectory estimation, with regards to reconstructing a 3D trajectory from a 2D trajectory, is commonly achieved using stereo or multi camera setups. Although projections from 3D to 2D suffer significant information loss, some methods approach this problem from a monocular perspective to address limitations of multi camera systems, such as requiring points in to be observed by more than one camera.
