  2. 6. Differential Protection for Arbitrary Three-Phase Power Transformers

    Author : Zoran Gajic; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric power systems; power transformers; differential protection; power system protection;

    Abstract : This thesis describes how to provide standardized, current based, differential protection for any three-phase power transformer, including phase-shifting transformers with variable phase angle shift and transformers of all construction types and internal on-load tap-changer configurations. The use of standard transformer differential protection for such applications is considered impossible in the protective relaying standards and practices currently applied. READ MORE

  4. 7. The emergence of routine enforcement of international investment law : Effects on investment protection and development

    Author : Love Rönnelid; Iain Cameron; Steffen Hindelang; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Investment law; enforcement; foreign direct investment FDI ; power; investment insurance; bilateral investment treaties BITs ; World Trade Organisation WTO ; Multilateral Investment Guarantee Agency MIGA ; International Centre for Settlement of Investment Disputes ICSID ; development; developmental state; regulatory space; development strategies; law and development; New York Convention; Aron Broches; Ibrahim Shihata; Wilhelm Röpke; Friedrich Hayek; rule of law; good governance; Public International Law; Folkrätt;

    Abstract : This dissertation explores how the enforcement of international investment law became so powerful. It does so by tracing the different legal developments that have enabled the strength of the present regime. In this respect, the two aims of providing investment protection and that of fostering economic development are examined. READ MORE

  6. 9. Data Integrity and Availability in Power System Communication Infrastructures

    Author : Ognjen Vuković; György Dán; Deepa Kundur; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyber security; power systems; communications; state estimation; distributed;

    Abstract : Society is increasingly dependent on the proper functioning of electric power systems. Today's electric power systems rely heavily on information and networking technology in order to achieve efficient and secure operation. READ MORE

  7. 10. Advances on Adaptive Fault-Tolerant System Components: Micro-processors, NoCs, and DRAM

    Author : Alirad Malek; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network-on-Chip; Quality-of-Service; Main memory; Micro-processors; Error-Correcting Codes; Reliability analysis; Adaptive fault tolerance;

    Abstract : The adverse effects of technology scaling on reliability of digital circuits have made the use of fault tolerance techniques more necessary in modern computing systems. Digital designers continuously search for efficient techniques to improve reliability, while keeping the imposed overheads low. READ MORE
