  1. 1. Exploring New Physics Through Collider and Gravitational Wave Measurements with Artificial Neural Networks: the Case Study of QCD-like Technicolor

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Ashar Ahmed Kamal; [2023]
    Nyckelord :Artificial Neural Networks; ANN; Beyond the Standard Model; BSM; parameter space scan; Physics and Astronomy;

    Sammanfattning : With physicists actively exploring Beyond the Standard Model (BSM) theories that may fill in the gaps of the Standard Model (SM), a fundamental question arises: which parameters hold physical significance? In this thesis, we present our initial progress towards the development of a model-independent artificial intelligence framework designed for conducting parameter space scans in BSM scenarios. Our framework incorporates several publicly available high-energy physics packages, namely SPheno, HiggsBounds, HiggsSignals, and CosmoTransitions. LÄS MER

  3. 2. Predicting user churn using temporal information : Early detection of churning users with machine learning using log-level data from a MedTech application

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

    Författare :Love Marcus; [2023]
    Nyckelord :User churn; Customer attrition; Artificial neural networks; Log-level analysis; Random forests; Decision trees; Användarbortfall; Kundbortfall; Artificiella neurala nätverk; logganalys; Slumpskogar; Beslutsträd;

    Sammanfattning : User retention is a critical aspect of any business or service. Churn is the continuous loss of active users. A low churn rate enables companies to focus more resources on providing better services in contrast to recruiting new users. LÄS MER

  4. 3. Unsupervised Detection of Interictal Epileptiform Discharges in Routine Scalp EEG : Machine Learning Assisted Epilepsy Diagnosis

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Författare :Shuai Shao; [2023]
    Nyckelord :EEG; electroencephalography; IED; interictal epileptiform discharges; spike detection; epilepsy; unsupervised; Fourier transform; STFT; short-time Fourier transform; CWT; continuous wavelet transform; DWT; discrete wavelet transform; ML; machine learning; ANN; artificial neural network; CNN; convolutional neural network; autoencoder; HMM; hidden Markov model; ECS; Euclidean distance of cumulative spectrum;

    Sammanfattning : Epilepsy affects more than 50 million people and is one of the most prevalent neurological disorders and has a high impact on the quality of life of those suffering from it. However, 70% of epilepsy patients can live seizure free with proper diagnosis and treatment. Patients are evaluated using scalp EEG recordings which is cheap and non-invasive. LÄS MER

  5. 4. Användning av ekologiska och närproducerade livsmedel i ämnet hem- och konsumentkunskap

    Kandidat-uppsats, Umeå universitet/Institutionen för kost- och måltidsvetenskap

    Författare :Ann-Charlott Olén; Carina Hemmarö; Filippa Svedlund; [2023]
    Nyckelord :ekologiskt; närproducerat; ramfaktorer; hem- och konsumentkunskap;

    Sammanfattning : Bakgrund Genom att handla närproducerat och ekologiskt är det möjligt att bidra till hållbar utveckling. Enligt det centrala innehållet för hem och konsumentkunskap ska elever utbildas att göra genomtänkta val av livsmedel som främjar deras hälsa, ekonomi och vår miljö.

  7. 5. Redo att fortsätta leverera? En kvantitativ undersökning om förekomst och betydelse av krisberedskapsplanering i svensk socialtjänst under coronapandemins inledning

    Master-uppsats, Lunds universitet/Socialhögskolan

    Författare :Ann Edlund; [2023]
    Nyckelord :disaster preparedness; disaster preparedness plan; disaster response; social services; covid-19 pandemic; Social Sciences;

    Sammanfattning : The aim of this study was to investigate the occurrence and variation in disaster preparedness planning, for particularly vulnerable groups, in Swedish social services at the beginning of the covid-19 pandemic. The aim was also to investigate whether disaster preparedness planning, as measured in this study, had a bearing on the number of deaths from covid-19 in special accommodation and home care for the elderly and disabled during 2020 and 2021.
