1. 1. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction

   Författare :Sasa Trajkovic; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VVA; Regenerative; Air-motor; Compressor; Pneumatic; Hybrid; Vehicle; Electric Hybrid; Drive Cycle; GT-Power; Simulink; FPGA;

   Sammanfattning : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. LÄS MER

3. 2. Selection schemes and neural networks in adaptive real-time control : predictive simulation adaptive control

   Författare :Anders Zachrison; Linköpings universitet; []
   Nyckelord :Adaptive Control; Real-Time; Self-Organizing Feature Maps; Pneumatic; Neural Networks; Evolutionary Algorithms; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The vision of self-aware machines was the starting point of this work. The idea is a machine having knowledge about itself and its surrounding environment, being able to react to changes in the environment. LÄS MER

4. 3. Superheated Steam Drying of Wood Chips in Pneumatic Conveying Dryers

   Författare :Christian Fyhr; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superheated steam; drying; pneumatic conveying; convective; non-spherical particles; wood; heat transfer;

   Sammanfattning : This thesis contains a fundamental investigation of a pneumatic conveying dryer. The model presented can be used both for design and rating purposes and, although the main emphasis is put on the drying of wood chips in superheated steam, the results can be used for other systems as well.

5. 4. Fluid Power Applications Using Self-Organising Maps in Condition Monitoring

   Författare :Anders Zachrison; Jan-Ove Palmberg; Magnus Sethson; Richard Burton; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid power; pneumatic; self-organizing maps; condition monitoring; Signal processing; Signalbehandling;

   Sammanfattning : Condition monitoring of systems and detection of changes in the systems are of significant importance for an automated system, whether it is for production, transport, amusement, or any other application. Although condition monitoring is already widely used in machinery, the need for it is growing, especially as systems become increasingly autonomous and self-contained. LÄS MER

7. 5. Study of a Pneumatic Hybrid aided by a FPGA Controlled Free Valve Technology System
