1. 21. Development of Typical Load Profiles on residential electricity consumption using attribute data on electric vehicles, heating systems and fuse sizes

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Industriell teknik

   Författare :Aikaterini Manousidou; Martina Lundberg; [2022]
   Nyckelord :Typical Load Profiles; electric vehicles; load curves; smart grid; electrification; Velander formula;

   Sammanfattning : It is time to phase out fossil fuels and invest our efforts in green energy production through a major restructuring of the energy system. At the same time, more people are acquiring electric vehicles (EVs), thus creating a higher demand of electricity, and solar panels, allowing the consumer to also be a micro-producer. LÄS MER

3. 22. Data-driven Dynamic Baseline Calibration Method for Gas Sensors

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Cheng Yang; [2021]
   Nyckelord :CO2 gas sensing; drift; dynamic baseline calibration; time series analysis; data-driven modeling; clustering; classification; CO2 gasavkänning; drift; dynamisk baslinjekalibrering; tidsserieanalys; datadriven modellering; kluster; klassificering;

   Sammanfattning : Automatic Baseline Correction is the state-of-the-art calibration method of non-dispersive infrared CO2 sensing, which is the standard CO2 gas monitoring method. In this thesis, we improve it by introducing the dynamic baseline based on environmental data. LÄS MER

4. 23. Understanding Traffic Cruising Causation : Via Parking Data Enhancement

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Författare :Mirza Jasarevic; [2021]
   Nyckelord :Machine Learning; Unsupervised Learning; Time Series; Parking; Dynamic Time Warping;

   Sammanfattning : Background. Some computer scientists have recently pointed out that it may be more effective for the computer science community to focus more on data preparation for performance improvements, rather than exclusively comparing modeling techniques. LÄS MER

5. 24. Anomaly Detection in District Heating using a Clustering based approach

   Magister-uppsats,

   Författare :Minh-Tung Nguyen; Metjan Baduni; [2021]
   Nyckelord :Anomaly Detection; Data Mining; Unsupervised Machine Learning; Clustering; DBSCAN; Time Series;

   Sammanfattning : The global demand for energy has increased in recent years. In Northern Europe and North America, centralized production and distribution of heat energy is commonly regarded as District Heating (DH). Efficient delivery of heat in the DH system is crucial not only for the building dwellers but even for companies that supply such energy. LÄS MER

7. 25. Agriculture monitoring using satellite data

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Graff Erik; [2021]
   Nyckelord :Sentinel; satellite; agriculture; monitoring; dynamic time warping; remote sensing;

   Sammanfattning : As technology advances, the possibility of using satellite data and observations to aid inagricultural activities comes closer to reality. Swedish farmers can apply for subsidies for their land in which crop management and animal grazing occurs, and every year thousands of manual follow-up checks are conducted by Svenska Jordbruksverket (Swedish Board of Agriculture) to validate the farmers’ claims to financial aid.
