  1. 16. Exploring the effects of IFRS on earning management : A comparative study of South Korean and Swedish manufacturing companies

    Kandidat-uppsats, Södertörns högskola/Institutionen för samhällsvetenskaper

    Författare :MiRi Lee; Jenny Cerpa Veliz; [2023]
    Nyckelord :Accounting regulation; IFRS; earning management; accruals; discretionary accruals.;

    Sammanfattning : The adoption of International Financial Reporting Standards (IFRS) has been a significant event in the accounting profession, as it provides a common language for financial reporting across the globe. The impact of IFRS adoption on earnings management practices in South Korean and Swedish manufacturing companies is studied in this research. LÄS MER

  3. 17. Utveckling av interna transportflöden: En fallstudie utförd på Volvo CE Braås om utmaningar idag och i framtiden med koppling till säkerhet och produktivitet

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för management (MAN)

    Författare :Linn Grahn; Astrid Olsson; [2023]
    Nyckelord :Spaghetti diagram; internal transport flows; logistics layout; challenges; approach; trucks; frequency; AGV; measurement of internal transport; lean production; Spagettidiagram; interna transportflöden; logistiklayout; utmaningar; angreppssätt; truckar; frekvens; AGV; mätning av interna transporter; lean production;

    Sammanfattning : Background: By optimizing a company's internal flows, several benefits, including reduction of waiting time and incidents, can be generated. A relevant starting point for the concept of lean production is the effort to reduce the amount of waste. A variant of an improvement tool is a so-called spaghetti diagram. LÄS MER

  4. 18. Enhancing failure prediction from timeseries histogram data : through fine-tuned lower-dimensional representations

    Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Vijay Jayaraman; [2023]
    Nyckelord :time-series prediction; time-series histogram analysis; Convolution Neural Network CNN ; Autoencoder; Weibull Time-to-Event WTTE ; Recurrent Neural Network RNN ; Engine turbo charger failure prediciton;

    Sammanfattning : Histogram data are widely used for compressing high-frequency time-series signals due to their ability to capture distributional informa-tion. However, this compression comes at the cost of increased di-mensionality and loss of contextual details from the original features. LÄS MER

  5. 19. Examining the Effects of AWGN Jamming on a Tactical Data Link Communication System

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

    Författare :Noor Schroen; [2023]
    Nyckelord :Tactical Data Links; VOACAP; HF; AWGN; Jamming; Tactical Data Links; VOACAP; HF; AWGN; Jamming; Tactical Data Links; VOACAP; HF; AWGN; Jamming;

    Sammanfattning : This master thesis investigates the jamming of Tactical Data Links (TDLs). The goal is to make a model that is capable of giving an overview of a communication system under jamming conditions, offering the user a suggestion for the best coding scheme and modulation to use in any given situation.

  7. 20. Capturing genes with high impact based on reconstruction errors produced by variational autoencoders

    Master-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Utz Lovis Rieger; [2023]
    Nyckelord :;

    Sammanfattning : In this work we present a novel method to extract potential hub genes, transcription factors and regions with densely interconnected protein-protein-interaction networks from RNAseq data. To achieve this we deploy variational autoencoders, a generative machine learning framework, and extract the gene-wise reconstruction errors. LÄS MER
