2. 1. Fault Isolation in Distributed Embedded Systems

   Author : Jonas Biteus; Erik Frisk; Jan Eric Larsson; Linköpings universitet; []
   Keywords : Fault diagnosis; Fault isolation; Distributed diagnosis; Embedded systems; Fault tree analysis.; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : To improve safety, reliability, and efficiency of automotive vehicles and other technical applications, embedded systems commonly use fault diagnosis consisting of fault detection and isolation. Since many systems are constructed as distributed embedded systems including multiple control units, it is necessary to perform global fault isolation using for example a central unit. READ MORE

5. 3. Analysing Fault Tolerance for Erlang Applications

   Author : Jan Henry Nyström; Bengt Jonsson; Sven-Olof Nyström; John Hughes; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; formal methods; symbolic evaluation; fault tolerance; erlang; Computer engineering; Datorteknik; Computer Systems; Datorteknik;

   Abstract : ERLANG is a concurrent functional language, well suited for distributed, highly concurrent and fault-tolerant software. An important part of Erlang is its support for failure recovery. Fault tolerance is provided by organising the processes of an ERLANG application into tree structures. READ MORE

   Abstract : Modern society is unquestionably heavily reliant on supply of electricity. Hence, the power system is one of the important infrastructures for future growth. READ MORE

7. 5. Environmental risk assessment of shipwrecks – Model development and application

   Author : Hanna Landquist; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bayesian updating; shipwreck; environmental risk assessment; fault tree analysis; decision support;

   Abstract : Potentially polluting shipwrecks containing oil or other hazardous substances pose a threat to the marine environment. This is a global problem and many shipwrecks stem from the Second World War having been deteriorating on the sea floor since then. Only in Swedish waters more than 300 wrecks are estimated to pose an environmental threat. READ MORE
