  2. 1. Improved remaining useful life estimations for on-condition parts in aircraft engines

    Author : Veronica Fornlöf; Anna Syberfeldt; Anders Skoogh; Högskolan i Skövde; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aircraft engine maintenance; Reliability; Remaining useful life; On-condition parts; Prognosis; Technology; Teknik; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Abstract : This thesis focuses on obtaining better estimates of remaining life for on-condition (OC) parts in aircraft engines. Aircraft engine components are commonly classified into three categories, life-limited parts (LLP), OC-parts and consumables. Engine maintenance typi-cally accounts for 10% to 20% of aircraft-related operating cost. READ MORE

  4. 2. Storage-Centric System Architectures for Networked, Resource-Constrained Devices

    Author : Nicolas Tsiftes; Thiemo Voigt; Per Gunningberg; Chenyang Lu; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Internet of Things; wireless sensor networks; resource-constrained devices; file system; database management system; virtual machine; data compression; reprogramming; checkpointing; Datavetenskap; Computer Science;

    Abstract : The emergence of the Internet of Things (IoT) has increased the demand for networked, resource-constrained devices tremendously. Many of the devices used for IoT applications are designed to be resource-constrained, as they typically must be small, inexpensive, and powered by batteries. READ MORE

  5. 3. On a learning system for industrial automation : Model-based control and diagnostics for decision support

    Author : Moksadur Rahman; Konstantinos Kyprianidis; Anders Avelin; Gunnar Bengtsson; John Hedengren; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Learning system; Supervisory system; Pulp and paper; Micro gas turbine; Process modelling; Model-based control; Diagnostics; Decision support; Anomaly detection; Fault detection; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Access to energy is fundamental to economic and technological advancement. Hence, the more the world develops, the greater the demand for energy becomes. Evidently, the production and consumption of energy alone account for more than 80% of global anthropogenic greenhouse gas (GHG) emissions. READ MORE

  6. 4. Real-time Locating Systems for indoor applications : the methodological customization approach

    Author : Bartosz Jachimczyk; Wlodek Kulesza; Alfonso Bahillo Martínez; Blekinge Tekniska Högskola; []

    Abstract : Emerging wireless technologies increase the potential and effectiveness of wireless Real-time Locating Systems (RTLSs), which precisely localize the position, and identify things and people in real time. Among many applications, RTLSs are widely used in the industrial sector for indoor logistics and safety applications. READ MORE

  7. 5. Stability of power systems with large amounts of distributed generation

    Author : Valerijs Knazkins; Lennart Söder; Ian A. Hiskens; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; engineering; electronics and electrical engineering; system science; Elektroteknik; Electrical engineering; Elektroteknik;

    Abstract : This four-part dissertation is essentially concerned with some theoretical aspects of the stability studies of power systems with large penetration levels of distributed generation. In particular, in Parts I and II the main emphasis is placed upon the transient rotor angle and voltage stability. READ MORE
