2. 1. Microstructural, Mechanical and Tribological Characterisation of CVD and PVD Coatings for Metal Cutting Applications

   Author : Mikael Fallqvist; Staffan Jacobsson; Mikael Olsson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; Friction; Wear; Coatings; CVD; PVD; Alumina; Metal cutting; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials; Steel Forming and Surface Engineering;

   Abstract : The present thesis focuses on characterisation of microstructure and the resulting mechanical and tribological properties of CVD and PVD coatings used in metal cutting applications. These thin and hard coatings are designed to improve the tribological performance of cutting tools which in metal cutting operations may result in improved cutting performance, lower energy consumption, lower production costs and lower impact on the environment.

6. 4. Towards Intent-Driven Systems

   Author : Johan Silvander; Mikael Svahnberg; Andreas Jacobsson; Blekinge Tekniska Högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; business intent; business support system; intent-driven system; compositional system;

   Abstract : Context: Software supporting an enterprise’s business, also known as a business support system, needs to support the correlation of activities between actors as well as influence the activities based on knowledge about the value networks in which the enterprise acts. This can be supported with the help of intent-driven systems. READ MORE
