  2. 1. A WCET Analysis Method for Pipelined Microprocessors with Cache Memories

    Author : Thomas Lundqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; real-time systems; data cache; infeasible paths; pipeline; instruction cache; dynamically scheduled processor; worst-case execution time; timing analysis; path analysis; timing anomaly;

    Abstract : When constructing real-time systems, safe and tight estimations of the worst case execution time (WCET) of programs are needed. To obtain tight estimations, a common approach is to do path and timing analyses. READ MORE

  4. 2. A timing approach to network-based anomaly detection for SCADA systems

    Author : Chih-Yuan Lin; Simin Nadjm-Tehrani; Mikael Asplund; Aditya P Mathur; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SCADA securuty; anomaly detection;

    Abstract : Supervisory Control and Data Acquisition (SCADA) systems control and monitor critical infrastructure in society, such as electricity transmission and distribution systems. Modern SCADA systems are increasingly adopting open architectures, protocols, and standards and being connected to the Internet to enable remote control. READ MORE

  6. 4. Tracing environmental change and human impact as recorded in sediments from coastal areas of the northwestern Baltic Proper

    Author : Lena Norbäck Ivarsson; Elinor Andrén; Thomas Andrén; Mikael Lönn; John Anderson; Södertörns högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; paleoecology; diatom stratigraphy; stable nitrogen isotopes; hypoxia; nutrient discharge; eutrophication; Medieval Climate Anomaly; Little Ice Age; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : The eutrophication of the Baltic Sea due to increased anthropogenic nutrient loads during the 20th century is well documented and studied. However, in the Baltic Sea drainage area, humans have affected the environment longer than the environmental monitoring can provide data for. READ MORE

  7. 5. Techniques to Tighten the Upper Bound on the ExecutionTime of Task-based Parallel Applications

    Author : Petros Voudouris; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scheduling; Multiprocessor; WCET; Uniform; Hard; multicore; Related; DAG; Real-Time; Dynamic; Unrelated; Makespan; Homogeneous; Parallel; Identical;

    Abstract : To use multiprocessors in hard real-time systems, schedulability analysis is needed to provide formally proven guarantees for the timing behavior of the system. Programming models for parallel applications, such as OpenMP, use pragmas to specify parts of the application as parallel tasks, for example, a function or a body of a loop. READ MORE
