1. 6. Towards Topography Characterization of Additive Manufacturing Surfaces

   Författare :AMOGH VEDANTHA KRISHNA; Bengt Göran Rosén; Frederic Cabanettes; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser-based Powder bed fusion; Fused deposition modeling; Structured light projection; Stylus profilometer; Multiple regression; Areal surface texture parameters; Profile parameters; Feature-based characterization; Power spectral density; Scale-sensitive fractal analysis; Confocal fusion; Additive manufacturing;

   Sammanfattning : Additive Manufacturing (AM) is on the verge of causing a downfall to conventional manufacturing with its huge potential in part manufacture. With an increase in demand for customized product, on-demand production and sustainable manufacturing, AM is gaining a great deal of attention from different industries in recent years. LÄS MER

3. 7. Oil consumption and Friction in a Piston Ring-Cylinder Liner assembly.-A multifunctional Surface Approach

   Författare :Cecilia Anderberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder liner surface; surface characterization; oil consumption; surface texture parameters;

   Sammanfattning : About a half of the frictional losses in an internal combustion engine come from the interactions between the piston assembly and cylinder liner surface. The tribological considerations in the contact between the piston ring and cylinder liner have attracted much attention over the past few decades. LÄS MER

4. 8. On Polishability of Tool Steels

   Författare :Sabina Rebeggiani; Bengt-Göran Rosén; Liam Blunt; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steels; polishability; surface characterisation; surface texture parameters; high gloss polishing; injection moulding;

   Sammanfattning : One of the world’s fastest growing industries is the plastic industry. Today’s ever increasing demands of high quality products, shorter lead times and reduced costs push development and research forwards. LÄS MER

5. 9. Calibration Procedure and Industrial Applications of Coherence Scanning Interferometer

   Författare :Olena Flys; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coherence Scanning Interferometer; Power Spectral Density; 3D parameters; Characterization; uncertainty;

   Sammanfattning : Countless industrial applications over the past decades have indicated the increased need to relate surface texture to surface function. Measurement and characterization of the areal nature of the surface allows the manufacturer to alter how the surface interacts with surroundings. LÄS MER

7. 10. Impacts of climate change on surface hydrology in the source region of the Yellow River

   Författare :Feifei Yuan; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source region of the Yellow River; climate change; summer precipitation; ENSO; teleconnection pattern; sea surface temperature; Xinanjiang model; Rainfall-Runoff process;

   Sammanfattning : The source region of the Yellow River contributes about 35% of the total water yield in the Yellow River basin playing an important role for meeting the downstream water resources requirements. The declining water availability caused by climate change in the source region of the Yellow River is expected to have severe repercussions for the 110 million basin inhabitants in terms of water resources affecting agricultural productivity, municipal, and industrial water supply.
