1. 6. Data and Visual Analytics for Cyber-physical Systems : Current Situation and Strategies for Action

   Författare :Didem Gürdür; Martin Törngren; Jad El-khoury; Helena Holmström Olsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

   Sammanfattning : Today, cyber-physical systems (CPS) exist everywhere in different sizes, with different functionalities and capabilities. CPS often support critical missions that have significant economic and societal importance. LÄS MER

3. 7. Making Interoperability Visible : A Novel Approach to Understand Interoperability in Cyber-Physical Systems Toolchains

   Författare :Didem Gürdür; Martin Törngren; Jad El-khoury; Erik Herzog; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyber-physical Systems Toolchains; Interoperability; Interoperability Assessment; Data Visualization; Visual Analytics.; Machine Design; Maskinkonstruktion;

   Sammanfattning : In CPS development and production environments, tightly integrated processes include different engineering disciplines, development and production departments, and software tools working together, where all of the technical engineering processes become strictly intertwined. CPS development and production toolchains have a highly heterogeneous nature, and supporting toolchain architects is necessary for improving the understanding of the interrelationships between tools.

4. 8. Design and optimization of parallel haptic devices : Design methodology and experimental evaluation

   Författare :Suleman Khan; Kjell Andersson; Jan Wikander; Ölvander Johan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical simulation; 6-DOF haptic devices; design methodology.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : The simulation of surgical procedures, in the case of hard tissues such as bone or teeth milling, using a haptic milling surgery simulator requires a haptic device which can provide high stiffness and transparency. To mimic a real milling process of hard tissue, such as for example creating a narrow channel or cavity, the simulator needs to provide force/torque feedback in 5–6 degrees of freedom (DOF). LÄS MER

5. 9. Improving Fuel Efficiency of Commercial Vehicles through Optimal Control of Energy Buffers

   Författare :Mohammad Khodabakhshian; Jan Wikander; Lei Feng; Johan Ölvander; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy buffer; Optimal control; Hybrid electric vehicle; Engine cooling system; Equivalent consumption minimization strategy; Model predictive control; Machine Design; Maskinkonstruktion;

   Sammanfattning : Fuel consumption reduction is one of the main challenges in the automotiveindustry due to its economical and environmental impacts as well as legalregulations. While fuel consumption reduction is important for all vehicles,it has larger benefits for commercial ones due to their long operational timesand much higher fuel consumption. LÄS MER

7. 10. Kinematic Control of Redundant Knuckle Booms with Automatic Path Following Functions

   Författare :Björn Löfgren; Jan Wikander; Arto Finland Helsinki University of Technology Visala; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic manipulator; redundancy; kinematic control; local optimization; knuckle boom; forest machine; forwarder; boom tip control; joystick control; simulations; path following; Construction engineering; Konstruktionsteknik;

   Sammanfattning : To stay competitive internationally, the Swedish forestry sector must increase its productivity by 2 to 3% annually. There are a variety of ways in which productivity can be increased. One option is to develop remote-controlled or unmanned machines, thus reducing the need for operator intervention. LÄS MER
