  • Filter clogging data collection for prognostics 
    Eker, Ömer Faruk; Camci, Fatih; Jennions, Ian K. (2013-12)
    Filtration is a critical process in many industrial systems to obtain the desired level of purification for liquids or gas. Air, fuel, and oil filters are the most common examples in industrial systems. Filter clogging is ...
  • A Hybrid Prognostic Methodology and its Application to Well-Controlled Engineering Systems 
    Eker, Ömer Faruk (Cranfield University, 2015-01)
    This thesis presents a novel hybrid prognostic methodology, integrating physics-based and data-driven prognostic models, to enhance the prognostic accuracy, robustness, and applicability. The presented prognostic methodology ...
  • Major challenges in prognostics: study on benchmarking prognostic datasets 
    Eker, Ömer Faruk; Camci, Faith; Jennions, Ian K. (PHM Society, 2012-12-31)
    Even though prognostics has been defined to be one of the most difficult tasks in Condition Based Maintenance (CBM), many studies have reported promising results in recent years. The nature of the prognostics problem is ...
  • A new hybrid prognostic methodology 
    Eker, Ömer Faruk; Camci, Fatih; Jennions, Ian K. (Prognostics and Health Management Society, 2019-03-08)
    Methodologies for prognostics usually centre on physics-based or data-driven approaches. Both have advantages and disadvantages, but accurate prediction relies on extensive data being available. For industrial applications ...
  • Physics-based Degradation Modelling for Filter Clogging 
    Eker, Ömer Faruk; Camci, Faith; Jennions, Ian K. (PHM Society, 2014-07-23)
    Separation of solids from fluid is a vital process to achieve the desired level of purification in industry. Contaminant filtration is a common process in a variety of applications in industry. Clogging of filter phenomena ...
  • Physics-based prognostic modelling of filter clogging phenomena 
    Jennions, Ian K.; Camci, Faith; Eker, Ömer Faruk (Elsevier, 2015-12-29)
    In industry, contaminant filtration is a common process to achieve a desired level of purification, since contaminants in liquids such as fuel may lead to performance drop and rapid wear propagation. Generally, clogging ...
