1. 1. The Application of Multivariate Statistical Process Control during Industrial Hot Isostatic Pressing Sintering Processes : A Case study at Seco Tools AB

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

   Författare :Karl Ericsson; [2023]
   Nyckelord :Multivariate statistical process control; Batch processes; Quality prediction;

   Sammanfattning : This Master's thesis focuses on improving the understanding and monitoring of the Hot Isostatic Pressing (HIP) sintering process used by Seco Tools AB to manufacture cemented carbides for cutting tools. While essential for producing cutting tools with superior hardness and toughness the HIP sintering process introduces a complex relationship between the selected process parameters and the achieved materials properties.

3. 2. Identifying subarctic river thermal and mechanical ice break-up using seismic sensing

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Stefania Ursica; [2021]
   Nyckelord :Ice break-up; River ice; Subarctic; Thermal melting; Mechanical break-up; Freeze-up; Environmental seismology; Seismic signals;

   Sammanfattning : River-ice break-up in high-latitude regions, despite its brevity, is a fundamental process, representing the most dynamic and complex period of fluvial processes. Moreover, ice break-up has significant cascading ecological effects, with a different severity for mechanical vs. LÄS MER

   Sammanfattning : Nouryon, formerly Akzo Nobel, is a world-leading manufacturer of particles. Already in the 70s, one part of Nouryon was founded in Stockvik where to this day still produce particles of the highest class. LÄS MER

5. 4. Alkali Circulation in the Blast Furnace - Process Correlations and Counter Measures

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

   Författare :Joel Carlsson; [2018]
   Nyckelord :Alkali; coke; experimental blast furnace; top gas; mass spectrometry; multivariate analysis;

   Sammanfattning : In blast furnace ironmaking one major challenge is to control and measure the alkalis circulating and accumulating in the blast furnace (BF). Alkali enter the BF with the primary raw material and will form a cycle where it is first reduced to metal at the lower parts forming gas. LÄS MER

7. 5. Quality Data Management in the Next Industrial Revolution : A Study of Prerequisites for Industry 4.0 at GKN Aerospace Sweden

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

   Författare :Robert Erkki; Philip Johnsson; [2018]
   Nyckelord :Industry 4.0; Smart Manufacturing; Internet of Things; Big Data; Quality Control; Statistical Quality Control; Multi-variate Analysis; Machine Learning; Cyber-Physical System; Quality Data Management;

   Sammanfattning : The so-called Industry 4.0 is by its agitators commonly denoted as the fourth industrial revolution and promises to turn the manufacturing sector on its head. However, everything that glimmers is not gold and in the backwash of hefty consultant fees questions arises: What are the drivers behind Industry 4. LÄS MER
