The various process parameters affecting the quality characteristics of the shock absorber during the process were identified using the Ishikawa diagram and by failure mode and effect analysis. The identified process parameters are welding process parameters (squeeze, heat control, wheel speed, and air pressure), damper sealing process parameters (load, hydraulic pressure, air pressure, and ...

abstract background: the number of women who select cesarean section due to fear of childbirth has increased. role play education seems to be a helpful method to remove or reduce the fear of childbirth. therefore, this study aimed to investigate the effect of role play education on primiparous women’s fear of natural delivery and their decision on the mode of delivery. materials and methods: in...

In this paper, numerical simulation of FRP composite cylinder tubes progressive crushing processes is conducted using LS-Dyna. Details on the numerical modeling strategy are given and discussed. It is found that triggers introduced in the numerical simulation can effectively model the bevel trigger at the end of the tubular specimens. It is also found that two-layer finite element model based o...

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 ...

trichoderma is a genus of asexually reproducing fungi that is present in all types of soils. trichoderma species have been recognized as antagonists of soil-borne and foliage pathogens and as efficient decomposers of cellulosic waste materials. moreover, they have the ability to increase plant growth and induce plant resistance. along with mycoparasitism, antibiotics and competition, induced re...

A mechanical model for the prediction of mode I delamination failure of a laminated double cantilever beam (DCB) type specimen is presented. The volume of material ahead of the crack tip that experiences high stresses due to the presence of the crack tip was replaced by a nonlinear elastic spring foundation. The volume undergoing global deformation due to the external loading was replaced by a ...

In semiconductor world, there is a new paradigm shift from chip-scaling to system-scaling to meet the ever-increasing electronic system demands in power saving, performance, and functionality (including memory bandwidth) increase, form factor improvement and cost reduction. This shift is also triggered by the growing concerns for industry to sustain Moore's Law. Innovations on wafer-...

The main research intent of this paper is to introduce the use of fault tree analysis (FTA) and failure mode and effects analysis (FMEA) in conjunction to analyse the risk and reliability of a complex mechatronic system in both qualitative and quantitative manner. The major focus is on handling imprecise and vague information with the help of fuzzy synthesis of information. A complex mechatroni...
