Automated anonymization of sensitive data on production unit

Kujawa Marcin, Piotrowski Robert

Journal of Automation Mobile Robotics and Intelligent Systems

2023

Vol. 17, No. 1

40--44

The article presents an approach to data anonymization with the use of generally available tools. The focus is put on the practical aspects of using open‐source tools in conjunction with programming libraries provided by suppliers of industrial control systems. This universal ap‐ proach shows the possibilities of using various operating systems as a platform for process data anonymization. An additional advantage of the described approach is the ease of integration with various types of advanced data analysis tools based both on the out‐of‐the‐box approach (e.g., business intelligence tools) as well as customized solutions. The discussed case describes the anonymiza‐ tion of data for the needs of sensitive analysis by a wider group of recipients during the construction of a predictive model used to support decisions.

Modelling and Measurement of Folk Guitar : Truss Rod and Strings in Numerical Analysis of Tone

Bielski Paweł Michał, Kujawa Marcin, Lubowiecka Izabela

2019

Vol. 44, No. 1

35--49

The study makes an attempt to model a complete vibrating guitar including its non-linear features, specifically the tension-compression of truss rod and tension of strings. The purpose of such a model is to examine the influence of design parameters on tone. Most experimental studies are flawed by uncertainties introduced by materials and assembly of an instrument. Since numerical modelling of instruments allows for deterministic control over design parameters, a detailed numerical model of folk guitar was analysed and an experimental study was performed in order to simulate the excitation and measurement of gitar vibration. The virtual guitar was set up like a real guitar in a series of geometrically non-linear analyses. Balancing of strings and truss rod tension resulted in a realistic initial state of deformation, which affected the subsequent spectral analyses carried out after dynamic simulations. Design parameters of the gitar were freely manipulated without introducing unwanted uncertainties typical for experimental studies. The study highlights the importance of acoustic medium in numerical models.
