  1. 1. A domain-specific language for protocol stack implementation in embedded systems

    Author : Yan Wang; Veronica Gaspes; Thorsteinn Rögnvaldsson; Dimiter Driankov; Julia Lavall; Rögnvaldsson Thorsteinn; Driankov Dimiter; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Computer and Systems Science; Datavetenskap;

    Abstract : Embedded network software has become increasingly interesting for both research and business as more and more networked embedded systems emerge. Well-known infrastructure protocol stacks are reimplemented on new embedded hardware and software architectures. READ MORE

  2. 2. Obtaining Accurate and Comprehensible Data Mining Models : An Evolutionary Approach

    Author : Ulf Johansson; Lars Niklasson; Tom Ziemke; Thorsteinn Rögnvaldsson; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Rule extraction; Ensembles; Data mining; Genetic programming; Artificial neural networks; Computer science; Datalogi; rule extraction; ensembles; data mining; genetic programming; artificial neural networks;

    Abstract : When performing predictive data mining, the use of ensembles is claimed to virtually guarantee increased accuracy compared to the use of single models. Unfortunately, the problem of how to maximize ensemble accuracy is far from solved. READ MORE

  3. 3. Methods to quantify and qualify truck driver performance

    Author : Iulian Carpatorea; Slawomir Nowaczyk; Thorsteinn Rögnvaldsson; Wahde Mattias; Högskolan i Halmstad; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Driver performance; heavy-duty vehicle; fuel economy; fuel consumption; fuel prediction; truck driver;

    Abstract : Fuel consumption is a major economical component of vehicles, particularly for heavy-duty vehicles. It is dependent on many factors, such as driver and environment, and control over some factors is present, e.g. route, and we can try to optimize others, e. READ MORE

  4. 4. A Self-Organized Fault Detection Method for Vehicle Fleets

    Author : Yuantao Fan; Thorsteinn Rögnvaldsson; Sławomir Nowaczyk; Erik Frisk; Högskolan i Halmstad; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Abstract : A fleet of commercial heavy-duty vehicles is a very interesting application arena for fault detection and predictive maintenance. With a highly digitized electronic system and hundreds of sensors mounted on-board a modern bus, a huge amount of data is generated from daily operations. READ MORE

  5. 5. Wisdom of the Crowd for Fault Detection and Prognosis

    Author : Yuantao Fan; Thorsteinn Rögnvaldsson; Sławomir Nowaczyk; Olga Fink; Högskolan i Halmstad; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Monitoring and maintaining the equipment to ensure its reliability and availability is vital to industrial operations. With the rapid development and growth of interconnected devices, the Internet of Things promotes digitization of industrial assets, to be sensed and controlled across existing networks, enabling access to a vast amount of sensor data that can be used for condition monitoring.
