2. 1. Design Issues in VLSI Implementation of Image Processing Hardware Accelerators - Methodology and Implementation

   Author : Hongtu Jiang; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Bildbehandling; image processing; Imaging; Teknik; Technological sciences; Controller Synthesis; Circuit design; FPGA; Image convolution; Image processing; Video segmentation; Signalbehandling; Electronics; Elektronik;

   Abstract : With the increasing capacity in today's hardware system design enabled by technology scaling, image processing algorithms with substantially more complexity can be implemented in a single chip with real-time performance. Combined with the demand for low power consumption or larger resolution seen in many applications such as mobile devices and HDTV, new design methodologies and hardware architectures are constantly called for to bridge the gap between designers productivity and what the technology could offer.

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Abstraction hierarchy; Angular timeline visualization; Air traffic complexity; Air traffic control; Air traffic controller; Conflict detection and resolution; Ecological interface design; Focus context visualization; Human-automation collaboration; Human–computer interaction; Information visualization; Interaction; Rate of climb or descent; Research through design; Safety-critical systems; Visual analytics; Visualization; Visualization design and evaluation methods; Work domain analysis;

   Abstract : Automation in today’s world supports human operators to accomplish several tasks in limited time. With more advanced automation and autonomous systems, the hu-mans’ role is shifting from hands-on operational tasks to supervisory tasks. READ MORE

6. 4. Contention-based Multiple Access Architectures for Networked Control Systems

   Author : Chithrupa Ramesh; Karl Henrik Johansson; Henrik Sandberg; Dawn Tilbury; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

   Abstract : Networked Control Systems (NCSs) use a wireless network for communication between sensors and controllers, and require a Medium Access Controller (MAC) to arbitrate access to the shared medium. Traditionally, a MAC for control systems is chosen primarily based on the delay it introduces in the closed loop. READ MORE

7. 5. Analysis and Design of Hybrid Control Systems

   Author : Jörgen Malmborg; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lyapunov theory; Mode switching; Multi-controllers; PID control; Simulation; Higher order sliding; Hybrid control; Sliding modes; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : Different aspects of hybrid control systems are treated: analysis, simulation, design and implementation. A systematic methodology using extended Lyapunov theory for design of hybrid systems is developed. The methodology is based on conventional control designs in separate regions together with a switching strategy. READ MORE
