  1. 11. Air quality around preschools in Gothenburg: an evaluation of measurement methods

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Emma Forsmalm; [2023-06-21]
    Nyckelord :low-cost sensors; passive diffusion samplers; pick-ups and drop-offs; regulatory measurements;

    Sammanfattning : In this study the air quality around four different preschools, chosen to represent different local traffic environments, was measured and the measurement methods used were evaluated. The aim was to compare the information retrieved using different methods, discuss the possible applications of them and finally see if more specific activities, in this case pick-ups and drop-offs, could be seen in the data retrieved.

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

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

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

    Sammanfattning : 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. LÄS MER

  4. 13. Navigating the Risks of Dark Data : An Investigation into Personal Safety

    Magister-uppsats, Linnéuniversitetet/Institutionen för informatik (IK)

    Författare :Anshu Gautam; [2023]
    Nyckelord :Dark data; Hidden data; Big data; Unstructured data; Missing data; Privacy; Cybersecurity; Personal data; Data storage; Consumer protection;

    Sammanfattning : With the exponential proliferation of data, there has been a surge in data generation fromdiverse sources, including social media platforms, websites, mobile devices, and sensors.However, not all data is readily visible or accessible to the public, leading to the emergence ofthe concept known as "dark data.

  5. 14. Development and Implementation of Techniques for the Simulation and Processing for Future SAR Systems

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Tim Kinnunen; [2023]
    Nyckelord :Synthetic Aperture Radar; SAR; Reverse Backprojection Algorithm; RBPA; Backprojection Algorithm; SAR simulator; SAR processing;

    Sammanfattning : Synthetic Aperture Radar (SAR) is a type of radar system that can generate high-resolution images with which one can detect subtle changes on the scale of centimetres from space. It can operate in any weather condition and during both day and night, making it unique compared to optical sensors. LÄS MER

  7. 15. Optimization of Thermal Comfort on Electric Buses : A Comprehensive Study on Passenger Satisfaction in Stockholm, Sweden

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Ellinor Hambraeus; Maxwell Minotta Cuervo; [2023]
    Nyckelord :Electric bus; Bus temperature; Thermal comfort; Energy efficiency; Predicted Mean Vote; Equivalent temperature v; Elbuss; busstemperatur; termisk komfort; energieffektivisering; Predicted Mean Vote; Ekvivalent temperatur vii;

    Sammanfattning : The transition towards electrification in the bus sector is necessary to achieve the global climate goals and has gained significant traction in recent years. However, there are critical challenges associated with this transition, one of them being the absence of excess heat that traditional combustion engines provided to warm the bus cabin. LÄS MER
