4. 2. Wear resistant low friction coatings for engine components

   Author : Per Lindholm; Sören Andersson; Rickard Larker; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering materials; cam; roller follower; carbon coating; engine test; finite element method; Konstruktionsmaterial; Construction materials; Konstruktionsmaterial;

   Abstract : Engine development today is driven by cost, performance and government regulations. Customers want cars and trucks to consume less fuel, last longer, pollute less and be safer. Several of the requirements have tribological associations. For example, product longevity can be improved by lowering friction and using more wear-resistant components. READ MORE

5. 3. Drum Brake Squeal

   Author : Johan Hultén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction induced; squeak; vibration; drum brake; squeal; instability; self-excited; noise;

   Abstract : Drum brake squeal is a common discomfort. The main goal of this thesis is to investigate the mechanisms that generate drum brake squeal and to create a base for the search for solutions. A series of steps towards the understanding of these mechanisms are taken. Firstly, a simple model for friction-induced vibration is presented. READ MORE

6. 4. Optimizing Ocean Feature Estimation and Tracking through Adaptive Sampling and Formation Control of Autonomous Underwater Vehicles

   Author : Joana Filipa Gouveia Fonseca; Karl H. Johansson; Nina Mahmoudian; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Increased ocean temperatures caused by climate change are expected to lead to more frequent and severe harmful algal blooms, which deteriorate water quality, cause human illness and fish mortality. Scientific understanding of algal blooms and their dynamics is limited due to the lack of data from such ocean phenomena. READ MORE

7. 5. Force-based control for human-robot cooperative object manipulation

   Author : Ramin Jaberzadeh Ansari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinesthetic perception; physical human-robot collaboration; system identification; human-robot interaction control;

   Abstract : In Physical Human-Robot Interaction (PHRI), humans and robots share the workspace and physically interact and collaborate to perform a common task. However, robots do not have human levels of intelligence or the capacity to adapt in performing collaborative tasks. READ MORE
