“…The data collected and the conclusions drawn can be used in the design of technological process, but they can equally well serve the task of building intelligent systems, as has already been demonstrated in previous works of the authors using rough set theory [12] and the logic of plausible reasoning [13] and others related with diagnostics [14] or [15].…”

AustemPereD DuctIle Iron mAnufActurIng DAtA AcquIsItIon Process WIth the use of semAntIc technIquesThe aim of this work was to propose a methodology supporting the task of collecting the comparative data on studies of the mechanical properties of ADI. Collecting of research data is an important step in the process of finding the optimum design solutions for newly made products -experimental data allow us properly calibrate the manufacturing process of ADI to let the final product achieve the required properties. Parameters of the ADI production process, i.e. the time and temperature of austenitising and austempering, as well as the alloying elements added to ductile iron affect the ADI properties. The design process can use research data collected, among others, from the Web. As stated in the article, the process of data acquisition can be supported by semantic technologies, including ontologies which are descriptive logic formalism.

“…This paper also deals with railway interlocking signaling installations with Uninterrupted Power Supply UPS capability for safety applications and predictive diagnostics. In [30], fault diagnostics of electric motors by non-invasive methods utilizing acoustic signals generated by the motor are proposed. The proposed approached reduces the cost and faults in motors.…”

Abstract:In this article a new distinct winding scheme is articulated to utilize three phase induction machines for multifunctional operation. Because of their rugged construction and reduced maintenance induction machines are very popular and well-accepted for agricultural as well as industrial purposes. The proposed winding scheme is used in a three phase induction machine to utilize the machine for multifunctional operation. It can be used as a three-phase induction motor, welding transformer and phase converter. The proposed machine design also works as a single phase induction motor at the same time it works as a three-phase to single phase converter. This new design does not need any kind of special arrangement and can be constructed with small modifications to any standard three-phase induction motor. This modified induction machine is thoroughly tested to determine its efficiency and other parameters and also hardware implementation results are provided in the article, which validate the design and construction.

“…This concept requires mathematical transformation of the sensor readings since the signal is affected by irregularities occurring in all three contact points of the sphere. It can be easily conducted with the use of Fourier transform [6,7]. angles between supports and the sensor axis [5] Sensor readings in a given point of the profile is a function of the angles between supports and the change of the displacement of the sensor tip in this point.…”

Spherical elements constitute significant group of machine parts. In particular, they are commonly applied in bearing industry. Spherical elements should be usually manufactured very precisely and their form deviations are relatively small. Deviations of balls used in rolling bearings usually do not exceed 1 micrometer. The problem of accurate measurement of spherical parts is complicated and standards do not provide too many recommendations referring to this problem. The paper presents up-to-date solutions of the problem of measurements of spherical parts. It also presents the method of sphericity measurements developed at Kielce University of Technology. In addition, measurement strategies are presented that are based on developed method.
