  1. 1. Measuring the Utility of Synthetic Data : An Empirical Evaluation of Population Fidelity Measures as Indicators of Synthetic Data Utility in Classification Tasks

    Master-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :Alexander Florean; [2024]
    Nyckelord :Synthetic Data; Machine Learning; Population Fidelity Measures; Utility Metrics; Synthetic Data Quality Evaluation; Classification Algorithms; Utility Estimation; Data Privacy; Artificial Intelligence; Experiment Framework; Model Performance Assessment; Syntetisk Data; Maskininlärning; Population Fidelity Mätvärden; Användbarhetsmätvärden; Kvalitetsutvärdering av Syntetisk Data; Klassificeringsalgoritmer; Användbarhetsutvärdering; Dataintegritet; Artificiell Intelligens; AI; Experiment Ramverk; Utvärdering av Modellprestanda;

    Sammanfattning : In the era of data-driven decision-making and innovation, synthetic data serves as a promising tool that bridges the need for vast datasets in machine learning (ML) and the imperative necessity of data privacy. By simulating real-world data while preserving privacy, synthetic data generators have become more prevalent instruments in AI and ML development. LÄS MER

  2. 2. Predicting inflow and infiltration to wastewater networks based on temperature measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Martin Åsell; [2024]
    Nyckelord :Inflow and Infiltration; I I; CNN; Linear regression;

    Sammanfattning : Sewer pipelines are deteriorating due to aging and sub optimal material selections, leading to the infiltration of clean ground and rainfall water into the pipes. It is estimated that a significant portion (up to 40-50%) of the water entering wastewater treatment plants is actually clean infiltrated water. LÄS MER

  3. 3. The Impact of Spin-offs on Shareholder Value : Evidence from the Swedish Market 1991-2022

    Master-uppsats, Uppsala universitet/Företagsekonomiska institutionen

    Författare :Moa Landing; Gustav Swedenborg; [2023]
    Nyckelord :Spin-offs; Corporate restructurings; Abnormal returns; Determinants of abnormal returns;

    Sammanfattning : This thesis uses an event study methodology to investigate the short- and long-term effect on shareholder value from Lex ASEA-approved spin-offs' on the Swedish market between 1991-2022. The impact of spin-offs has been examined by estimating the effects on the parent firm, the spun-off entity, and a value-weighted pro-forma entity. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Isak Evaldsson; Henrik Paulcén; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 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.

  5. 5. Implementing Kalman Filtering Algorithms for Estimating Clamp Force on a Test Rig : Testing the Power and Limitations of Unscented Kalman Filter-based Estimations

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

    Författare :Tim Naser; [2023]
    Nyckelord :Clamping Froce; Kalman Filtering; Unscented Kalman Filtering; Tightening; Consequence of User Errors During Tightening; Velocity Profiles; Klämkraft; Kalman Filtrering; Unscented Kalman Filtrering; Åtdragning; Konsekvens av Användarfel Under Åtdragning; Hastightersprofiler.;

    Sammanfattning : his study explores clamp force estimation using Unscented Kalman Filtering (UKF) in torque-controlled tightening scenarios with various velocity profiles. Previous research has explored the impact of velocity levels on target torque and clamping force, but only using hand-held tools. LÄS MER
