Making the correct maintenance strategy decision for industrial multistage machines (MSTM) is a constant challenge manufacturers. Preventive strategies are most popular and provide interesting results but cannot prevent unexpected failures consequences, such as time lost production (TLP). In these cases, predictive should be used to maintain appropriate level of operation time. This research ai...

An improved highly accelerated life stress test (HALST) procedure and modeling method was developed to evaluate the reliability of multilayer ceramic capacitors with base-metal electrodes (BMEs). Reliabilities of ceramic capacitors with precious-metal electrodes (PMEs) and BMEs are discussed. A combination of leakage current and mean-time-to-failure (MTTF) measurements under accelerated life st...

Transport and binding of molecules to specific sites are necessary for the assembly and function of ordered supramolecular structures in cells. For analyzing these processes in vivo, we have developed a confocal fluorescence fluctuation microscope that allows both imaging of the spatial distribution of fluorescent molecules with confocal laser scanning microscopy and probing their mobility at s...

In industrial globalization “safety” is emerging as most noticing and valued factor. The main intention of this design of safety systems is to avoid unexpected accidents and to achieve reduction in dangerous environment according to health and property risk. The different safety functions considered to increase the relative safety of the plant are combinable and all together named as safety ins...

Starting with the meaning of the word quality, diverse concepts connoted by the term are examined. Instead of a bathtub curve, the desirable shape of a failure rate covering the entire life of a good product, which might be called hockey-stick line, is introduced. From the hockey-stick line and the definition of reliability, two measurements are extracted. The terms r-reliability (failure rate)...

We consider a clustered wireless sensor network (WSN) under epidemic-malware propagation conditions and solve the problem of how to evaluate its reliability so as to ensure efficient, continuous, and dependable transmission of sensed data from sensor nodes to the sink. Facing the contradiction between malware intention and continuous-time Markov chain (CTMC) randomness, we introduce a strategic...

This chapter deals with the problems occur in the welding under the consideration of many causes of defects such as cracking, distortion, porosity, inclusion and undercutting. Welding is very useful for every industry. It is used as a fabrication and sculptural that joins the two parts of materials, generally metals or thermoplastic, through a restricted amalgamation from a suitable combination...
