Trains of DB Schenker Rail AG create a continuous logfile of diagnostics data. Within the company, methods to use this data in order to increase train availability and reduce costs are researched. An interesting and promising application is the prediction of train component failure. In this paper, we developed and evaluated a method that utilizes the diagnostic data to predict future component ...

When test is done right, that is to an acceptable quality specification (and without impeding productivity and cost), defective parts fail the screening process. Without splitting hairs on definition, diagnosis and debug digs deeper to determine why the part is unacceptable. Troubleshooting how and why a part (or system) fails is important. For example, this may be needed for yield improvement,...

In this paper, we present a framework, called Embedded-System Safety Aspects Visualization (ESSAVis), that is a system prototype designed to analyze the safety aspects of embedded systems. The ESSAVis prototype provides a 3D environment that aids in detecting infected components in the hardware of the target embedded system. The prototype also provides an abstract representation for the failure...

The hardmetal cutting tools used in machining are submitted to extreme conditions in terms of temperature and mechanical loading. A better understanding of the failure of cutting tools and capability to predict tool life are key factors in the development of new tool materials with improved mechanical behaviour. Main failure mechanisms are wear, thermal–mechanical fatigue and brittle fracture. ...

Determining battery lifetimes is beset with difficulties. Performance data are not generally available and costly to generate since large numbers of batteries must be tested to destruction. Furthermore, the required test period to verify the predictions is often greater than commercial decision lead time. While the reliability predictions in the following section are very useful, they are desig...

The demand for volume deployment of photonic components has increased, and with it the need to effectively manufacture in a reproducible and cost effective way. Therefore, it is important to keep the assembly process consistent and stable. A simple shear test setup was used in this study to determine the shear force that can be used as an instant indicator to the process stability of fiber arra...

BDI programming languages provide a well developed route to implementing intelligent agents. However, as such agents are increasingly being used to work in, and interact with, real environments their treatment of external actions needs to be improved. In this paper we describe a mechanism for handling actions which have durations and failures. In particular we note that where an action has a du...

Information-centric networks are an interesting new paradigm for distributing content on the Internet. They bring up many research challenges, such as addressing content by name, securing content, and wide-spread caching of content. Caching has caught a lot of attention in the research community, but a lot of the work su↵ers from a poor understanding of the di↵erent metrics with which caching p...

This paper presents observed failure modes for a geobag structure from a series of physical modeltests. Six hundred bags were employed to observe the failure in terms of friction force, water depth, flow rateand bag aging. Three different failures are reported. An analysis of the effect of bag aging shows that 52% ofsaturated bags gain weight in the range 0 to 5% and about 70% of in...

The survival signature has been introduced to simplify quantification of reliability of systems which consist of components of different types, with multiple components of at least one of these types. The survival signature generalizes the system signature, which has attracted much interest in the theoretical reliability literature but has limited practical value as it can only be used for syst...
