1. 21. Particle generation for geometallurgical process modeling

   Författare :Pierre-Henri Koch; Jan Rosenkranz; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; ore texture; texture classification; breakage simulation; process modeling; Mineralteknik; Mineral Processing;

   Sammanfattning : A geometallurgical model is the combination of a spatial model representing an ore deposit and a process model representing the comminution and concentration steps in beneficiation. The process model itself usually consists of several unit models. LÄS MER

3. 22. Multivariate Synergies in Pharmaceutical Roll Compaction : The quality influence of raw materials and process parameters by design of experiments

   Författare :Nabil Souihi; Johan Trygg; Jukka Rantanen; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Roll compaction; dry granulation; mannitol; dicalcium phosphate; design of experiments; orthogonal projections to latent structures; critical quality attributes; tablet manufacturing; quality by design; design space; near-infrared chemical imaging; texture analysis; modeling; scale up; instrumented roll; Johanson model;

   Sammanfattning : Roll compaction is a continuous process commonly used in the pharmaceutical industry for dry granulation of moisture and heat sensitive powder blends. It is intended to increase bulk density and improve flowability. LÄS MER

4. 23. On the Mechanisms behind the Tribological Performance of Stellites

   Författare :Daniel H. E. Persson; Sture Hogmark; Staffan Jacobson; Mikael Olsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Stellite; Co-based; phase transformation; fcc; hcp; texture; alignment; low-friction; laser cladding; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : This thesis reveals the tribological mechanisms behind the intrinsic low friction potential of the Co-based family of alloys called Stellites. Although being an established and important group of materials, a satisfactory explanation to why they exhibit low-friction properties under severe sliding conditions has not previously been found in the literature.

5. 24. Radiomics in cancer prognosis : applications and limitations of quantitative texture analysis

   Författare :Yi-Hua Zhang; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Medical imaging has become an integral part of clinical diagnostics since the discovery of X- rays at the end of the 19th century. Recent advances in computing power have opened up the possibility to extract quantitative data from medical images beyond what is visible to the human eye, so-called radiomics. LÄS MER

7. 25. Characterisation of Functional Pressing Die Surfaces

   Författare :Johan C Berglund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional correlation; functional surface; functional filtration; pressing die; multi-scale analysis; characterisation; finish milling; texture anisotropy; polishing; surface topography;

   Sammanfattning : The manufacture of dies and moulds is a critical aspect of many production systems since the manufacturing and try-out of new dies and moulds often is essential in determining the lead-time and quality of a new production system. In the automotive industry, many new car models are introduced each year and for each of these models, a new set of pressing dies has to be designed and manufactured. LÄS MER
