The main objective of predictive maintenance is to identify a small problem before it becomes a big problem. Thermal Imaging is one of the best tools for predictive maintenance. This technology allows us to see a small temperature increase before it becomes a catastrophic failure. Modern technology is able to more accurately evaluate potential problems. The technology allows for collecting better and more extensive data than was previously available — from which very detailed temperature analysis can be made. Thermal inspections of electrical and mechanical systems will show you the necessary areas in your company on which to concentrate your efforts. By focusing specifically on those areas that need to be maintained, you will be saving money several ways: avoiding downtime in production, non-productive wages, greater repair costs and lost time. By performing annual thermal inspections you will also benefit by maintaining the most favorable insurance rating. Paper published with permission.

We are in the era of the fourth industrial revolution. Which highlights adaptability, monitoring, digitisation and efficiency in manufacturing as a result of the design of new smart mechanical systems. A central role in Industry 4.0 is played by maintenance and, within this framework, we define and review condition-based predictive maintenance. Thereafter, we propose a new class of smart mechanical systems that self-optimise utilising both condition-based maintenance and dynamic system modification. Akin to smart structures, smart mechanical systems will recognise and predict faults or malfunctions and, subsequently, self-optimise to restore desirable system behaviour. Potential benefits include increased reliability and efficiency while reducing cost without the requirement of highly skilled technicians. Thus, small and medium-sized enterprises are a specific target of such technology due to their increasing level of automatisation within Industry 4.0.

Mechanical looseness is one of the common failures detected on machines and mechanical systems. In this research, resonance effect that is a problem for mechanical systems has been studied within perspective of mechanical looseness failure through a bearing. A test setup has been designed, built and located in laboratory environment. A bearing in the electrical motor, that is one of the elements in the test setup construction, has been chosen for acquiring data throught acoustic, vibration and electrical consumption during the test. The purpose of this research is testing condition monitoring of mechanical looseness failure and resonance for studying comparison of different predictive maintenance perspectives. The test was implemented at the electricity frequency of 40.5 Hz that forced the electrical motor through identified rotation speed. According to the analysis results, inspecting of mechanical looseness failure and resonance problem has been detected as the most effectively by vibration analysis.

In modern technology, vibration signal is to be utilized in predictive maintenance application,more often when Dynamic Signal Analyzer (DSA) is invented. Unballance in rotor cause significantdeflection on rotated shaft and possible damage the machine. DSA is used in monitoring a condition ofbig rotation machines such as turbin, compressor, pump and generator. This research used double rotorsshaft system which was supported with journal bearing as a modification from the real rotation machines.Two of vibration characteristic as a sign of abnormal condition in rotation machine are unballance andoil whirl phenomenon. Meanwhile, oil whirl is seen in many rotation machines that use journal bearingas support its shaft. For rotation machine with high speed, oil whirl phenomenon can cause resonance inthe system, and then become the oil whip. Based on this condition that is very reasonable for makingearly detection, identification, and looking for the solution to prevent not wanted incident.

Jacob Ulrich: “The Time and Space of Sleep: Reading Sleep in In Search of Lost Time”This article examines the significance and structuring function of sleep and sleep related instances in Marcel Proust’s In Search of Lost Time. Through close readings of narrative conceptions of time in the ouverture the article shows how descriptions of the narrator’s sleep both destabilize the narrative and form a narrative pattern to which the overall structure of the novel adheres. Secondly, the article focuses on spatiality and sleep, particularly the narrator’s bedroom, which appears as a privileged place where certain perceptual conditions are displayed and experimented with. Descriptions of sleep in the novel thus form a boundary or threshold that negotiates between inner and outer modes of perception. The article concludes by addressing, in more general terms, the potential problems involved when studying ‘sleep and literature’.
