Nowadays Inertial Measurement Units are largely implemented in several applications, such as automotive and self‑driving vehicles, Unmanned Aerial Vehicles, cellular phones, robotics, artificial intelligence and many others. Despite this, recent literature doesn’t cover properly both the characterization of the dynamical metrological performances and the reliability analysis when microelectronic devices operate under real environmental conditions. Trying to fill this gap, the characterization of an Inertial Measurement Unit under vibration condition is proposed in this work by means of a...

While investigating rotating faults in vibration signals, one of the typical symptoms is the presence of repetitive transients, which are characterized by impulsive and cyclostationarity signature. The approach quite popular nowadays in the industry for their detection is time-frequency techniques.Those techniques are mainly analysis tools as opposed to processing tools, and in any case, are unable to offer a versatile methodology that applies to all mechanical signals in all circumstances. The paper is motivated by ideas borrowed from thermodynamics, where transients are seen as departures...

Maintenance of industrial processes, plants and complex systems is, of course, extremely important to ensure the quality of work performed, ensure employee safety, timely prediction of the necessary downtime, which of course affects business efficiency. The service life of the plant is extended by regular maintenance inspections and monitoring of malfunctions to eliminate the onset of failure even in the event of complete deviations to avoid a major system failure. Recently, the system has been monitored using automatic BMS / SCADA systems, in addition to which additional regular visual...

The 21st century manufacturing technology is unimagined without the various CAM toolpath generation programs. The aim of developing the toolpath strategies which offered by the software is to ensure the longest possible tool lifetime and more efficiency of the cutting method. In this paper, we aim is to compare the efficiency of the 3 types of EdgeCam tool path strategy in the curse of micro-milling of the ceramic material. During the analysis we dealt with the evaluation of the dimensional distortion of the manufactured geometries and the recorded vibration signals.

Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. The objectives of HVAC systems are to provide an acceptable level of occupancy comfort and process function, to maintain good indoor air quality, and to keep system costs and energy requirements to a minimum. Performing a reliability prediction provides an awareness of potential equipment degradation during the equipment life cycle. Reliability under a range of conditions is one of the most important requirements to guarantee in HVAC installed on trains. Predicting the...

This paper proposes a hybrid model (HyM) for a heating, ventilation and air conditioning (HVAC) system installed in a passenger train. This HyM fuses data from two sources: data taken from the real system and synthetic data generated using a physics-based model of the HVAC. The physical model of the HVAC was developed to include the sensors located in the real system and new virtual sensors reproducing the behaviour of the system while a failure mode (FM) is simulated. Statistical features are calculated from the selected signals. These features are labelled according to the related FMs and...

Encapsulated test parts, like microswitches, clocks, relays, sensor systems, lamps, electronic control units are used in diverse industrial applications. Therefore these components have to fulfill a variety of requirements. This includes leak tightness against dirt and moisture (e.g. IP 67), as the penetration of liquids can cause serious malfunction. In the definition of the IP protection classes a description how to perform a suitable laboratory test is given. In the production line, this laboratory test cannot be transferred and used. Widespread is the use of the test medium compressed...

This paper discusses the problem of the residual compensation effect. The residual compensation effect referred to as the fault compensation effect, is an underrated issue of a modelbased diagnostics. In part, this is justified due to the relatively low probability of such an effect. However, there is a belief that the inability to isolate faults in case of the residual compensation effect is the evident drawback of the model-based diagnostics. This paper shows that under some conditions, the problem of fault compensation could be overcome. In this connection, the necessary and sufficient...

Requests for laboratory accreditation according to the ISO/IEC 17025 standard have become more and more frequent, both to commercial and scientific laboratories. Although Ruđer Bošković Institute (RBI) is a scientific institute whose primary role is scientific research, it also provides professional services to public/customers. Traditionally, these services were not expected to be accredited. However, customers’ needs changed and the need for accredited services provided by the RBI’s laboratories emerged. Therefore, the need for quality management system (QMS) complying with the ISO/IEC...

The Robert Koch Institute (RKI) is Germany’s leading governmental scientific institution in the field of biomedicine and moreover one of the most essential bodies for the safeguarding of public health. It issues independent recommendations for medical specialists, state and local health authorities and the federal government. Furthermore, there is a brisk exchange of information and advice with its partner countries, for instance to improve preparing disease outbreaks and health crises. In conclusion the Robert Koch Institute contributes to health protection not only in Germany, but across...
