Innovative Instrument Design for Systems with Varying Frequency Inputs / Critical Thinking in Science and Education

ABSTRACT: Innovative Instrument Design for Systems with Varying Frequency Inputs

The paper provides some practical aspects of frequency multiplication applied to the synchronization of power grid instruments operating at unknown frequency or in a regime with a constant small frequency drifts. The circuit that realizes the multiplication is intended to replace the device’s internal clock and to guarantee fixed pre-defined (programmable) number of samples per period of the input signal. This prevents spectrum leakage and other issues associated with spectrum calculations from time samples using common time-frequency transformations. Consequently, the architecture of the device implementing this solution can be simplified through elimination of digital circuits for various filtering and numerical corrections. Two possible architectures for the realization of this device are presented and the restrictions necessary to ensure adequate positioning of harmonics along the frequency axis are shown.

ABSTRACT: Critical Thinking in Science and Education

Critical thinking in science means the ability to distinguish facts from assumptions, analyzing data without bias, and asking questions that lead to deeper understanding. Through critical thinking, scientists make discoveries that change our perspective on the world. Critical thinking represents the foundation upon which the entire scientific method is built. Without the ability to think critically, scientific progress would be significantly limited, and our ability to solve problems, innovate, and build a sustainable future would be diminished. NANO-THINK project (Teaching critical thinking in science through nano-learning and virtual exchange principles) is dedicated to developing a specialized learning program that actively encourages the development of critical thinking in various scientific disciplines. By utilizing distance learning technology and concept of nano-learning, the project aims at providing an efficient and unique learning experience. This paper presents key results of the GAP analysis conducted on a sample of 585 students and 218 teaching staff from Serbia, Croatia, Montenegro and Bosnia and Herzegovina, as well as further steps in this project. The activities are implemented in partnership involving the following institutions: Faculty of Health Studies from Rijeka, which is also the project coordinator, the Nikola Tesla Institute from Belgrade, University of Donja Gorica, Medical Faculty from Graz, International Burch University, the Verlab Institute from Sarajevo, company B-Solutions from Tivat and the International Academy of Science and Arts in Bosnia and Herzegovina.

Biography of the presenter

Prof. Dr. Boris Antić works at the Faculty of Technical Sciences in Novi Sad since 1999 at the Department of Electrical Measurements, Department of Energy, Electronics and Telecommunications. He is the recipient of the prestigious scholarship of the German Academic Exchange Service (DAAD) in the period 2001/2002. He is the author of several papers at domestic and international conferences and foreign journals, and has published several textbooks. His research career is focused on the fields of electrical measurements, telecommunications and Earth observation. He is well versed in European regulations and policies. Since 2008 to the present, he has actively participated in numerous TEMPUS projects (USP-OF, TIU, KNOWTS, STREV), ERASMUS+ projects (NANO-THINK), FP7 projects (AgroSense, BalkanGeoNet, EOPower, IASON, InnoSense and Fractals) and H2020 projects (SMART4ALL). In 2014, he worked as an external associate of the Joint Research Centre (JRC) of the European Commission and the national contact person for scientific support for the implementation of the Danube Strategy and the Danube Reference Infrastructure for Spatial Data (DATA and services). He was the first head of the Technology Transfer Centre at the University of Novi Sad. He holds the position of General Director of Smart Grid Solutions doo Novi Sad.
