  1. 16. Bearing Diagnosis Using Fault Signal Enhancing Teqniques and Data-driven Classification

    University essay from Linköpings universitet/Fordonssystem

    Author : Benjamin Lembke; [2019]
    Keywords : Bearing diagnosis; rolling element bearings; predictive maintenance; signal processing; fault detection; gearbox diagnosis; support vector machine; svm; binary classification; one class classification; machine learning; feldetektion; diagnos; feldiagnos; växellåda; signalbehandling; maskininlärning;

    Abstract : Rolling element bearings are a vital part in many rotating machinery, including vehicles. A defective bearing can be a symptom of other problems in the machinery and is due to a high failure rate. Early detection of bearing defects can therefore help to prevent malfunction which ultimately could lead to a total collapse. READ MORE

  3. 17. Microgrid Safety and Protection Strategies

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Aryudha Hartono; [2018]
    Keywords : IB-RES; grid-connected mode; islanded mode; short circuit; IED; directional zero and negative sequence current protection; unbalanced load flow; protection coordination; fault ride-through;

    Abstract : One of the challenging issues with the Microgrid is that the bidirectional power flow providedby the distributed generator (DG) which modify the fault current level. Furthermore, theinverter based-renewable energy source (IB-RES) limits the total fault current contributionto the grid due to its thermal capability. READ MORE

  4. 18. "L'eau c'est la vie": Seeking Sustainable Water Access and Community Participation in Rural Cameroon

    University essay from Linnéuniversitetet/Institutionen för samhällsstudier (SS)

    Author : Eva Beal; [2016]
    Keywords : Cameroon; Tikar; community-based management; rural water schemes; functionality; handpumps; participation; institutional bricolage;

    Abstract : In the rural water scheme projects across sub-Saharan Africa, the participatory Community Based Management model has become the norm. Through initial financing by oustide funders, the goal is for communities to independently take on the financing of the operation and maintenance (O&M) of the improved water schemes, thereby ensuring sustainability and functionality of the pumps.

  5. 19. Cylinder Pressure Sensor based Engine Combustion and Fuel System Diagnostics

    University essay from KTH/Fordonsdynamik

    Author : Michael Korres; [2016]
    Keywords : ;

    Abstract : Nowadays, the developed diagnostics models and software are not capable of locating the root cause of an emerging malfunction, or in other words the responsible component, while the vehicle is up and running. In most cases they are solely able to provide the driver with indications that a fault has been detected within a group of components. READ MORE

  6. 20. Locating Faults on Energized Airfield Lighting Power Cables

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Dennis Honkanen; Simon Anderjon; [2016]
    Keywords : Fault Location; State of Health; Airfield; Lighting; LED; Fault; Series Circuit; Technology and Engineering;

    Abstract : The purpose of this study is to investigate the feasibility of both online and offline fault location and state of health technologies for airport series circuits used to provide power to light fixtures on the runway. In current series circuits, only some ground faults can be detected and no automated fault location or state of health features are available. READ MORE
