1. 1. Usage of databases in ARINC 653-compatible real-time systems

   Uppsats för yrkesexamina på avancerad nivå, Linköpings universitet/Institutionen för datavetenskap; Linköpings universitet/Institutionen för datavetenskap

   Författare :Martin Fri; Jon Börjesson; [2010]
   Nyckelord :ARINC 653; INTEGRATED MODULAR AVIONICS; EMBEDDED DATABASES; SAFETY-CRITICAL; REAL-TIME OPERATING SYSTEM; VXWORKS;

   Sammanfattning : The Integrated Modular Avionics architecture , IMA, provides means for runningmultiple safety-critical applications on the same hardware. ARINC 653 is aspecification for this kind of architecture. It is a specification for space and timepartition in safety-critical real-time operating systems to ensure each application’sintegrity.

3. 2. Performance Optimisation with a Real-Time Database

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Andreas Wikensjö; [2009]
   Nyckelord :;

   Sammanfattning : Embedded control systems are gaining an increasing amount of responsibility in today's vehicles and industrial machines. As mechanical components are replaced by software, the complexity of control systems and the amount of data they are responsible for greatly increase. LÄS MER

4. 3. Zohmg—A Large Scale Data Store for Aggregated Time-series-based Data

   Master-uppsats, Chalmers tekniska högskola/Institutionen för data- och informationsteknik

   Författare :Per Andersson; Fredrik Möllerstrand; [2009]
   Nyckelord :;

   Sammanfattning : Analyzing data at a massive scale is one of the biggest challenges that Last.fmis facing. Interpreting patterns in user behaviour becomes a challenge whenmillions of users interact in billions of combinations; the data sets must beanalyzed, summarized and presented visually. LÄS MER

5. 4. Investigation of a real-time communication interface between C200 and a computer

   Y-uppsats, Luleå tekniska universitet/Tillämpad fysik, maskin- och materialteknik/Datorstödd maskinkonstruktion

   Författare :Eric Eklund; [2009]
   Nyckelord :Vehicle testing; KWP2000; CCP; CAN; RS-232;

   Sammanfattning : Scania is developing a telematic unit for remote communication called Communicator 200 (C200). The purpose of the unit is to collect vehicle data and send it back to Scania. C200 is a black box hidden in the top drawer with no interaction towards the driver. Field tests are performed to verify functions in C200. LÄS MER

7. 5. Partition Aware Database Replication : A state-update transfer strategy based on PRiDe

   Magister-uppsats, Högskolan i Skövde/Institutionen för kommunikation och information

   Författare :Johan Olby; [2007]
   Nyckelord :Data Replication; Distributed Databases; PRiDe; MANET; Optimistic Replication; Real-Time Systems;

   Sammanfattning : Distributed real-time databases can be used to support data sharingfor applications in wireless ad-hoc networks. In such networks, topology changes frequently and partitions may be unpredictable and last for an unbounded period. In this thesis, the existing database replication protocol PRiDe is extended to handle such long-lasting partitions. LÄS MER
