a r t i c l e i n f o Keywords: Failure mode and effects analysis Data envelopment analysis Overall risks Risk priority ranking Failure mode and effects analysis (FMEA) is a method that examines potential failures in products or processes and has been used in many quality management systems. One important issue of FMEA is the determination of the risk priorities of failure modes. In this paper ...

In this paper, dissimilar resistance spot welding of AISI 1075 eutectoid steel to AISI 201 stainless steel is investigated experimentally. For this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. The effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...

Wind turbine failure and downtime can often compromise the profitability of a wind farm due to their high impact on the operation and maintenance (O&M) costs. Early detection of failures can facilitate the changeover from corrective maintenance towards a predictive approach. This paper presents a cost-e↵ective methodology to combine various alarm analysis techniques, using data from the Supervi...

This article presents the comparison of SingleGate SOI and Multi-Gate SOI MOSFETs. In the first part we have presented two main fundamental problems of the “ultimate” (sub-10-nm) MOSFET scaling of Single-Gate geometry: the exponential growth of power consumption and sensitivity to fabrication uncertainties. These factors have played the decisive role in for eventual transfer of the CMOS industr...

Aims. We present VRi photometric observations of the quadruply imaged quasar HE0435-1223, carried out with the Danish 1.54 m telescope at the La Silla Observatory. Our aim was to monitor and study the magnitudes and colors of each lensed component as a function of time. Methods. We monitored the object during two seasons (2008 and 2009) in the VRi spectral bands, and reduced the data with two i...

Qualitative simulation interpreted by the use of functional labels to identify significant system behaviour has been shown to be a useful technique for automating design analysis tasks such a Failure Modes and Effects Analysis. However, increasing sophistication of the systems to be analysed means that it is becoming increasingly important that the correct timing of these system functions be in...

numerous types of development projects, Adams reported similar numbers, where only about one-fourth of all projects entering development become a market success (2004). Datta and Mukerjee (2001) stated that “successful project completion depends to a great extent on the early identifi cation of immediate risks.” Jiang et al. (2002), using factor analysis, confi rmed their hypothesis that risks ...

We investigated how constraints imposed by the concurrent visual context modulate the effects of prior gender and action cues as well as of stereotypical knowledge during situated language comprehension. Participants saw videos of female or male hands performing an action and then inspected a display showing the faces of two potential agents (one male and one female face) as they listened to Ge...

In this report presents our experience with automating parts of the FMEA process using a model checker. As the case study a minepump control system is used, that prevents flooding in a mineshaft
