1. 21. Verifying Information Flow Control Libraries

   Författare :Marco Vassena; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Information Flow Control (IFC) is a principled approach to protecting the confidentiality and integrity of data in software systems. Intuitively, IFC sys- tems associate data with security labels that track and restrict flows of information throughout a program in order to enforce security. LÄS MER

3. 22. Hardware and Software Mechanisms for Control Flow Checking

   Författare :Ghassem Miremadi; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault tolerance; error detection latency; signature monitoring; watchdog processor; dependability evaluation; transient faults; physical fault injection; concurrent error detection; control flow checking; error detection coverage;

   Sammanfattning : The improvement of dependability in computing systems requires the evaluation of fault tolerance mechanisms such as error detection, error recovery and reconfiguration. Central to this thesis is an experimental evaluation of several hardware and/or software implemented mechanisms for the concurrent detection of control flow errors. LÄS MER

4. 23. Toward Secure and Reliable Networked Control Systems

   Författare :André Teixeira; Henrik Sandberg; Karl H. Johansson; Kameshwar Poolla; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Security and reliability are essential properties in Networked Control Systems (NCS), which are increasingly relevant in several important applications such as he process industry and electric power networks. The trend towards using non-proprietary and pervasive communication and information technology (IT) systems, such as the Internet and wireless communications, may result in NCS being vulnerable to cyber attacks.

7. 25. Multilevel Power Converters with Smart Control for Wave Energy Conversion

   Författare :Deepak Elamalayil Soman; Mats Leijon; Jan Isberg; Sebastain Nielebock; Gopal Mondal; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multilevel power converter; FPGA control; Wave Energy; Three-level boost converter; Three-level buck-boost converter; Variable-renewable-energy; Three-level neutral point clamped inverter; Linear generator; DC-link; AC2AC direct converter; Modular multilevel converter; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : The main focus of this thesis is on the power electronic converter system challenges associated with the grid integration of variable-renewable-energy (VRE) sources like wave, marine current, tidal, wind, solar etc. Wave energy conversion with grid integration is used as the key reference, considering its high energy potential to support the future clean energy requirements and due the availability of a test facility at Uppsala University.
