A review on detection and diagnosis illustrate that process.faults can be detected when based on the estimation of unmeasurable process parameters and state variables. Abstract-The supervision of technical processes is the subject of increased development because of the increasing demands on reliability and safety. The use of process computers and… (More)
For the improvement of reliability, safety and efficiency advanced methods of supervision, fault-detection and fault diagnosis become increasingly important for many technical processes. This holds especially for safety related processes like aircraft, trains, automobiles, power plants and chemical plants. The classical approaches are limit or trend… (More)
Model based feedback control strategies for electrohydraulic braking and active steering systems in passenger cars are considered. Simulation results with a complex vehicle model and measurements from test drives with a real car are shown for brake control. For a µ-split road surface additional drive dynamics control is required like ESP or active front… (More)
PURPOSE This prospective study aimed to compare sonoelastography, B-mode ultrasonography, and mammography in terms of their ability to distinguish benign from malignant breast lesions. We also assessed how the diagnostic value of sonoelastography differs between palpable and clinically occult lesions. MATERIALS AND METHODS Evaluation revealed a total of… (More)
