  2. 16. Development of intelligent robot systems based on sensor control

    Author : Mikael Fridenfalk; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Envision; kinematics singularities.; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik; Igrip; Matlab; 6D; 3D; laser scanning; arc sensing; seam tracking; robotic welding; Asimov; ROWER-2; FUSE; virtual prototyping; rapid prototyping; software development; simulation; virtual sensor; Robot; sensor control;

    Abstract : Sensor based control systems increase flexibility and autonomy in robotics. One of the most common applications in robotics is welding, which is often limited to objects with fine tolerances. READ MORE

  4. 17. Discrete-Event Simulation, Operations Analysis, and Manufacturing System Development: Towards Structure and Integration

    Author : Lars Holst; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integration; Manufacturing System Development; Discrete-Event Simulation; Production technology; Produktionsteknik;

    Abstract : After more than four decades of presence in the manufacturing industry, discrete event simulation has established itself as a powerful technology for a wide range of strategic, tactical, and operational applications in production, logistics, and supply chain management. Discrete event simulation software packages - although not entirely adequate - are relatively capable, and methodologies for performing simulation projects are reasonably well-developed and documented.

  5. 18. Aspects on Interference and Diversity in Wireless Networks

    Author : Fredrik Florén; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; Elektronik och elektroteknik; Electronics and Electrical technology; feedback; multiuser communication; diversity; throughput; packet radio networks; Interference; frequency hop communication;

    Abstract : This thesis deals with two topics in wireless communications: interference between frequency-hopping (FH) networks, and multiuser diversity. The work on FH treats a system where FH is used to provide simultaneous access to the channel for multiple uncoordinated wireless networks. READ MORE

  6. 19. Coding and Modulation for Wideband CDMA

    Author : Ola Wintzell; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbo codes.; Electronics and Electrical technology; channel coding; impulse radio; coordinated transmission; pre-coding; cellular radio capacity; Direct sequence code division multiple access DS-CDMA ; pulse position hopped code division multiple access PPH-CDMA ; Elektronik och elektroteknik; Telecommunication engineering; Telekommunikationsteknik;

    Abstract : Wideband CDMA (Code Division Multiple Access) is one of the key technologies for future mobile communication systems. This thesis studies various coding and transmission methods for wideband CDMA communications. In a cellular environment, the system performance depends on the interference from other cells.
