EnergiesThe result of continuous efforts in the development of power theory, Budeanu’s power theory was successfully extended. The mathematical description that has been proposed is based on another concept, namely the Currents’ Physical Components (CPC) theory.

Energies, 2023 This article presents methods of reactive power compensation using passive elements in the form of a capacitor (C) or choke (L) and an LC structure selected in such a way as to lead to the minimization of the reactive current (reactive power) of a single-

EnergiesThis article presents principles for matching reactance parameters for minimizing balancing compensation, whose mathematical origins come from the Currents’ Physical Components (CPC) theory developed by Czarnecki. The construction of minimizing balancing

EnergiesBudeanu’s power theory, in its fundamental version, describes single-phase sinusoidal and nonsinusoidal systems. Over time, this elementary description has been extended to three-phase three-wire and four-wire systems, regardless of power conditions ...

Journal of Consumer Behaviour, Volume 21, Issue 6, Page 1420-1439, November/December 2022., 2022 Abstract Grocery shopping is a major contributor to unsustainable consumption in the developed world. This study constructs a hierarchy of sustainable grocery shopping (SGS), using a broad range of SGS consumption activities that contribute to an individual's aggregate grocery shopping. We confirm the suitability of Rasch modelling to construct the SGS

Tourist taxation as a sustainability financing mechanism for mass tourism destinations
International Journal of Tourism Research, Volume 24, Issue 4, Page 577-592, July/August 2022., 2022 Abstract Tourism taxation is one of the tools that can effectively contribute to obtaining resources that favor the development of policies to improve sustainability and the tourist experience in the destination. In this context, the objectives of this research are, on the one hand, to identify tourist preferences when offered 15 different taxes and ...

Geometric Algebra for teaching AC Circuit Theory
International Journal of Circuit Theory and Applications, Volume 49, Issue 11, Page 3473-3487, November 2021., 2021 We present a novel way to teach AC circuit theory under the paradigm of geometric algebra. By formulating this new mathematical framework, the paper presents and discusses how GA can be of help to avoid the limitations of the usage of complex algebra in nonsinusoidal AC circuits.

IET Smart Grid, Volume 2, Issue 4, Page 491-503, December 2019., 2019 The increasing aggregation of renewable‐based distributed generating units besides the impressive growing usage of non‐linear loads raises unwanted challenges for traditional power terms definition in power engineering. This fact consequently affected the performance of the conventional control frameworks and industrial compensation techniques. In this

Theorems of compensation and Tellegen in non‐sinusoidal circuits via geometric algebra
The Journal of Engineering, Volume 2019, Issue 4, Page 3409-3417, April 2019., 2019 Presently, it is not possible to corroborate Tellegen's theorem or to articulate the compensation theorem in the frequency domain when considering all the harmonics simultaneously. The circuit analysis approach based on geometric algebra is used here to solve these two challenges.
