  1. 1. Audio Anomaly Detection in Cars

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Asma Hussein; [2023-09-11]
    Nyckelord :Audio Anomaly detection; Outlier detection; Machine learning; Mel Frequency; Chroma;

    Sammanfattning : Audio anomaly detection in the context of car driving is a crucial task for ensuring vehicle safety and identifying potential faults. This paper aims to investigate and compare different methods for unsupervised audio anomaly detection using a data set consisting of recorded audio data from fault injections and normal "no fault" driving.

  3. 2. Prisbubblor på Sveriges bostadsmarknad: Om det existerar ett långsiktigt samband mellan svenska bostadsrättspriser och fundamentala utbuds- och efterfrågefaktorer.

    Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

    Författare :Lisa Axelsson; Kajsa Jonsson; [2023-07-06]
    Nyckelord :;

    Sammanfattning : Denna studie ämnar undersöka om det finns tecken på en prisbubbla genom att studera om det existerar ett långsiktigt samband mellan bostadsrättspriser och fundamentala utbuds- och efterfrågefaktorer i Stockholms, Göteborgs och Karlstads kommuner under tidsperioden 2000–2021. Mellan åren 1996 och 2021 ökade de svenska bostadsrättspriserna med 800% vilket är betydligt mer i jämförelse med den ekonomiska levnadsstandarden som under 2000-talet endast ökade med 60%. LÄS MER

  4. 3. Demand Forecasting of Automobile Spare Parts after the End-of-Production - A review of demand forecasting models

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Abid Ali; Arosha Ratnayake; [2023-07-03]
    Nyckelord :Demand forecasting; Spare parts; Automobile; End-of-Production EOP ; PRISMA; AHP; MCDM;

    Sammanfattning : Demand forecasting of spare parts plays a crucial role in automobile industry where it generally requires a significant attention in controlling inventory. It is possible to maintain an optimal stock level when there is a continues supply at the Original Equipment Manufacturers (OEMs). LÄS MER

  5. 4. The road to an accurate cost estimation in engineer-to-order manufacturing - A case study of cost estimation accuracy within advanced technology development in a defence and security company

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Lawin Anwar; Sandra Barría Colliander; [2023-07-03]
    Nyckelord :Engineer-to-order; new product development; cost management; cost engineering; cost estimation error; cost overruns; cost estimation accuracy; project management;

    Sammanfattning : Estimating the costs of a project is a vital part of manufacturing organisations as estimations are what set the basis for the price of the products. Precise estimates allow for effective planning and resource allocation, ensuring that the necessary materials, equipment, and personnel are available to complete the project on time and within budget.

  7. 5. Exploring the Determinants of Agricultural Commodity Returns

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Andreas Blidberg; Ludwig Skans; [2023-06-29]
    Nyckelord :Agricultural commodities; Energy commodities; Granger causality; Vector Error Correction Model; VECM; Impulse Response Functions; IRF;

    Sammanfattning : This paper investigates the Granger causal relations between agricultural commodity returns and several potential determinants using a multivariate Vector Error Correction Model (VECM) and Impulse Response Functions (IRF). Agricultural commodities are critical for global food supply, and understanding their determinants is crucial for policymakers and investors. LÄS MER
