  1. 11. Restoring Consistency after Network Partitions

    Författare :Mikael Asplund; Simin Nadjm-Tehrani; Paul Ezhilchelvan; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; distributed systems; fault tolerance; network partitions; dependability; integrity constraints; Computer science; Datalogi;

    Sammanfattning : The software industry is facing a great challenge. While systems get more complex and distributed across the world, users are becoming more dependent on their availability. As systems increase in size and complexity so does the risk that some part will fail. LÄS MER

  3. 12. Architecting and Modeling Automotive Embedded Systems

    Författare :Ola Larses; Martin Törngren; Kurt Sandkuhl; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Automotive; Embedded systems; Architecture; Dependability; Cost; Systems engineering; Systemteknik;

    Sammanfattning : Dealing properly with electronics and software will be a strong competitive advantage in the automotive sector in the near future. Electronics are driving current innovations and are at the same time becoming a larger part of the cost of the vehicle. LÄS MER

  4. 13. Modeling and Tuning Security from a Quality of Service Perspective

    Författare :Stefan Lindskog; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; network security; quality of service QoS ; tunable security; dependability; security service; data protection; security evaluation; Datavetenskap; Computer Science;

    Sammanfattning : Security has traditionally been thought of as a system or network attribute that was the result of the joint endeavors of the designer, maintainer and user, among others. Even though security can never reach a level of 100%, the aim has been to provide as much security as possible, given the boundary conditions in question. With the advent of, e.g. LÄS MER

  5. 14. On Impact and Tolerance of Data Errors with Varied Duration in Microprocessors

    Författare :Örjan Askerdal; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault injection; dependability; error propagation analysis; fault tolerance; error effect analysis;

    Sammanfattning : The evolution of high-performance and low-cost microprocessors has led to their almost pervasive usage in embedded systems such as automotive electronics, smart gadgets, communication devices, etc. These mass-market products, when deployed in safety-critical systems, require safe services albeit at low recurring costs.
