  1. 21. The role of fault management in the embedded system design

    Författare :Carlo Vitucci; Daniel Sundmark; Thomas Nolte; Fredrik Asplund; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Management; Resilient system; Recovery methodology.; Computer Science; datavetenskap;

    Sammanfattning : In the last decade, the world of telecommunications has seen the value ofservices definitively affirmed and the loss of the connectivity value. This changeof pace in the use of the network (and available hardware resources) has ledto continuous, unlimited growth in data traffic, increased incomes for serviceproviders, and a constant erosion of operators’ incomes for voice and ShortMessage Service (SMS) traffic.

  3. 22. Network and user-level traffic adaptation for collaborative-workspace applications

    Författare :Jeremiah Scholl; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pervasive Mobile Computing; Distribuerade datorsystem;

    Sammanfattning : Collaborative workspace applications based on IP-multicast offer a scalable solution for computer supported human-to-human communication. Although Internet-wide multicast access is not a reality, multicast deployment is steadily increasing on subnets, such as corporate and campus networks. LÄS MER

  4. 23. Aspects of Power Consumption in Coherent Fiber-Optical Communication Systems

    Författare :Lars Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical frequency comb; Fiber-optical communication; power consumption; carrier-recovery; Raman amplification; energy-efficiency; optical amplifier; digital signal processing; coherent detection; erbium-doped fiber amplifier; phase-tracking;

    Sammanfattning : The power consumption of coherent fiber-optical communication systems is becoming increasingly important, for both environmental and economical reasons. The data traffic on the Internet is increasing at a faster pace than that at which optical network equipment is becoming more energy efficient, which means that the overall power consumption of the Internet is increasing.

  5. 24. A Journey towards Sustainable Small Wastewater Treatment Systems in Low and Lower–Middle Income Countries

    Författare :Claudia Cossio Grageda; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater treatment system; local stakeholders; operation and maintenance; sustainability assessment; institutional dimension; EVAS tool EVAluation of Sustainability ; low and lower-middle income countries; sustainability indicators; resource recovery; performance assessment;

    Sammanfattning : The sustainability of small wastewater treatment systems (WWTSs) in low and lower-middle income countries represents a challenge in terms of functionality and optimal performance in the ongoing effort to treat wastewater sufficiently to enable safe discharge or reuse. The reuse of wastewater is a common practice in these countries, especially where water resources are scarce. LÄS MER

  7. 25. Voltage Source Converters with Energy Storage Capability

    Författare :Hailian Xie; Hans-Peter Nee; Lennart Ängquist; Ambra Sannino; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Voltage source converter; StatCom; Energy storage; Active power compensation; Phase jump; Voltage dip; VSC; Weak network; Flux modulation; deadbeat control; Electric power engineering; Elkraftteknik;

    Sammanfattning : This project deals with voltage source converters with energy storage capability. The main objective is to study the possible benefits of energy storage to a power system with a VSC as the interface between them. First of all, a converter control system is proposed for a two level VSC. LÄS MER
