  1. 1. Validation of Finite Element Model of a Tetra Pak Package

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Warsame Mohamed Ali; Abdullahi Abdi Hashi; [2023]
    Nyckelord :Abaqus; HDPE; Package testing; Validation; Abaqus; HDPE; Pakettestning; Validering;

    Sammanfattning : There is a high dependency on accurate finite element models in the packaging industry for concept selection, design and virtual validation of packages. One of themost used materials for these packages is High-Density Polyethylene (HDPE). Thismaterial is highly anisotropic, strain rate dependent and has different behavior intension and compression.

  3. 2. Aligning Business Intelligence initiatives with business strategies : Identifying alignment challenges and mitigators in SMEs

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Anton Börjesson; [2023]
    Nyckelord :Business intelligence; SMEs; IT and business alignment; IT alignment challenges; Business Intelligence; SMF; IT och affärsanpassning; Utmaningar med IT-anpassning;

    Sammanfattning : Purpose: The purpose of this study is to enrich the literature, by increasing the understanding of how business intelligence (BI) initiatives can be aligned with the business strategy in small and medium enterprises (SMEs). Thus, prior research is insufficient in terms of BI and IT alignment research in SMEs. LÄS MER

  4. 3. Machine Learning of Laser Ultrasonic Data to Predict Material Properties

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Filip Tuvenvall; [2023]
    Nyckelord :Machine Learning; Laser Ultrasonics; Material Properties; Steel; Hardness of Steel;

    Sammanfattning : The hardness of steel is an important quality parameter for several industrial applications. Conventional mechanical testing is used in quality testing for material hardness and the method is time-consuming, can cause material mix-ups, and results in material waste. LÄS MER

  5. 4. A VVER1000 primary side model in Apros

    Master-uppsats, KTH/Fysik

    Författare :Karl-Edvin Strand; [2023]
    Nyckelord :Apros; VVER1000; PWR; Modelling; HPIS; Boron acid; Apros; VVER1000; PWR; Modellering; HPIS; Borsyra;

    Sammanfattning : Nuclear power plants generate electricity by means of splitting atoms. The basic safety requirements and objectives are to protect the people, society, and the environment from radiological accidents, limit harmful effects of ionizing radiation during operation and take all reasonable practical steps to prevent radiological accidents.
