In unternehmensweiten Work ow Management Systemen WfMS kann die von der WF Engine zu bew altigende Last sehr gro werden Au erdem werden hohe Anforderungen an die Verf ugbarkeit eines solchen Systems gestellt Deshalb wurden in der Literatur zahlreiche Architekturen f ur skalierbare WfMSe vorgeschlagen die auf unterschiedlichen Verteilungen der WF Engine basieren Diese Architekturen werden in dem...

Because of legislative regulations like OBDII, on-board diagnosis has gained much interest lately. A model based approach is suggested for the diagnosis of the air intake system of an SI-engine. Important research issues are modeling concepts, residual generation and evaluation, overall performance, and limiting factors. The diagnosis system is based on a non-linear semi-physical model and uses...

This paper presents a new method for on-board fault diagnosis for the air-path of spark ignition (SI) engines. The method uses an adaptive radial basis function (RBF) neural network to classify pre-defined possible faults from engine measurements to report the type and size of the fault. The RBF fault classifier adapts its widths and weights to model the time-varying dynamics of the engine and ...

The paper presents an application of artificial neural network to modelling emission from Diesel engine. In our study six independent engine control variables have been identified and used. In order to found the relations between engine control parameters and emission the radial artificial neural network (ANN) has been applied. The ANN has been trained on the base of measurement results whose c...

The paper describes correlation between combustion knock intensity and combustion rate calculated as the heat release rate from combustion pressure traces of a hydrogen fuelled spark ignited engine. Unlike a gasoline spark ignited (SI) engine, the hydrogen fuelled engine can easily generate knock during combustion at working conditions similar to a gasoline engine. However, the hydrogen knock d...

Commercial, aluminum die-cast alloys are subject to long-term stresses leading to viscoelastic material responses resulting in inefficient engine operation and failure. Constant load creep tests were conducted on aluminum die-casting alloys: B-390, eutectic Al-Si and a 17% Si-Al alloys. Rupture occurred in the primary creep regime, with the eutectic alloy having the longest times to failure. Pr...
