1. 6. Characterisation of Nonlinear Structural Dynamic Systems in Conceptual Design

   Författare :Niclas S Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural dynamics; Model order reduction; Nonlinear characterisation; Multi-body dynamics; Frequency response functions; Multisines; Response classification; Driveline systems; Concept design analysis; Stepped-sine; Support vector machine;

   Sammanfattning : The engine and driveline systems of passenger cars generates and distributes the necessary driving power and are major contributors to vehicle emissions, noise and vibrations, etc. More environmental friendly technologies under development are expected to intensify and add new comfort related problems, since most of them affect vibration sources or system damping.

3. 7. The Robustness and Energy Evaluation of a Linear Quadratic Regulator for a Rehabilitation Hip Exoskeleton

   Författare :Rabé Andersson; Niclas Björsell; Daniel Rönnow; Gianni Borghesan; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip Rehabilitation Exoskeleton; Robust Controller; Energy Consumption; Series Elastic Actuator SEA ; LQR Control; Luenberger State Observer; Torque Control; Höftexoskelett för rehabilitering; Robust reglering; Energiförbrukning; serieelastiskt manöverdon SEA ; LQR reglering; Luenberger State Obser-ver; Moment reglering;

   Sammanfattning : The implications of gait disorder, muscle weakness, and spinal cord injuries for work and age-related mobility degradation have increased the need for rehabilitation exoskeletons. Specifically, the hip rehabilitation exoskeletons due to a high percentage of the mechanical power is generated by this join during the gait cycle. LÄS MER

4. 8. SiC-FET Gas Sensors Developed for Control of the Flue Gas Desulfurization System in Power Plants Experimental and Modeling : Experimental and Modeling

   Författare :Zhafira Darmastuti; Anita Lloyd Spetz; Lars Ojamäe; Niclas Lindqvist; Mike Andersson; Bilge Saruhan-Brings; Linköpings universitet; []
   Nyckelord :SiC-FET sensors; temperature cycle operation; detection mechanism studies; SO2; H2S;

   Sammanfattning : Electricity and power generation is an essential part of our life. However, powergeneration activities also create by-products (such as sulphur oxides, nitrogen oxides,carbon monoxide, etc), which can be dangerous when released to the atmosphere. LÄS MER

5. 9. SiCFET gassensors : theory, developent, and applications to flue gas cleaning processes  in power plants

   Författare :Zhafira Darmastuti; Anita Lloyd Lloyd Spetz; Lars Ojamäe; Mike Andersson; Niclas Lindqvist; Mikael Larsson; Jaco Visser; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Environmental and health concerns lead to stricter regulations on power plant emission. Sensors play an important role, not only as part of the process control to ensure that the effluent stays under the regulated values, but also to increase the pollution removal efficiency and to decrease the reagent consumption.

7. 10. The Impact of Dissolved Matter on Fiberline Processes

   Författare :Caroline Wilke; Ulf Germgård; Niclas Andersson; Juha Fiskari; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bleach plant control; Carbonate; Carryover; Chlorine dioxide bleaching; COD; Dissolved lignin; Dissolved matter; Fiberline control; Filtrate; Hexenuronic acid; Hydrogen peroxide bleaching; Kappa number; Oxygen delignification; Wash loss; Chemical Engineering; Kemiteknik;

   Sammanfattning : The impact of dissolved matter on the performance of four fiberline process stages was investigated: oxygen delignification, hot acid treatment, chlorine dioxide bleaching, and hydrogen peroxide reinforced alkaline extraction. In particular the impact on delignification due to dissolved lignin was studied. LÄS MER
