  1. 1. Exploring Alarm Data for Improved Return Prediction in Radios : A Study on Imbalanced Data Classification

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Matematiska institutionen

    Författare :Sofia Färenmark; [2023]
    Nyckelord :Imbalanced data classification; LASSO; Boruta; SVM; RFC; neural network; decision tree; AUC; AUPRC;

    Sammanfattning : The global tech company Ericsson has been tracking the return rate of their products for over 30 years, using it as a key performance indicator (KPI). These KPIs play a critical role in making sound business decisions, identifying areas for improvement, and planning. LÄS MER

  3. 2. LPI waveforms for AESA radar

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Andreas Sjöberg; [2020]
    Nyckelord :Radar LPI waveform AESA;

    Sammanfattning : The purpose of low probability of intercept (LPI) radar is, on top of the standard requirements on a radar, to remain undetected by hostile electronic warfare (EW) systems. This can be achieved primarily by reducing the amount of radiated power in any given direction at all times and is done by transmitting longer modulated pulses that can then be compressed digitally in order to retain range resolution.

  4. 3. Big Data in Small Tunnels : Turning Alarms Into Intelligence

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

    Författare :Oscar Olli; [2020]
    Nyckelord :Alarm system; Correlation analysis; LSTM; Time series prediction;

    Sammanfattning : In this thesis we examine methods for evaluating a traffic alarm system. Nuisance alarms can quickly increase the volume of alarms experienced by the alarm operator and obstruct their work. We propose two methods for removing a number of these nuisance alarms, so that events of higher priority can be targeted. LÄS MER

  5. 4. Ground validation and bias correction of GPM-IMERG V6 satellite precipitation product over Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Mojtaba Moravej; [2020]
    Nyckelord :satellite precipitation product; bias correction; GPM-IMERG; Monte Carlo; evaluation; rain; Earth and Environmental Sciences;

    Sammanfattning : This study attempts to assess and correct the performance of Integrated Multi-satellite Retrievals for Global Precipitation Measurement (GPM-IMERG) final run daily precipitation product across Sweden. The performance of GPM-IMERG version 6 final run was evaluated against 677 rain gauges in a period from 12 March 2014 to 31 May 2019. LÄS MER

  7. 5. The impact of wind conditions on wind turbines

    Master-uppsats, KTH/Energiteknik

    Författare :Lovisa Eriksson Petersen; [2016]
    Nyckelord :;

    Sammanfattning : The world is facing global warming and the challenge to reduce greenhouse gas emissions. Wind power is a renewable source of energy with no greenhouse gas emissions when operating. Therefore, it could contribute in this challenge. LÄS MER
