A study of the transient processes in the physical model of the electric power systems with predominant part of the renewable energy sources [PDF]
E3S Web of Conferences, 2021 The renewable energy take part in the most of the electric power systems in the modern world. The part of this type of energy in the global electric power system, as well as in the local scale, increases with the setting the stricter requirements for ...

CoRR, 2021 The complex representation of real-valued instantaneous power may be written as the sum of two complex powers, one Hermitian and the other non-Hermitian, or complementary. A virtue of this representation is that it consists of a power triangle rotating around a fixed phasor, thus clarifying what should be meant by the power triangle.

Active Currents, Power Factor, and Apparent Power for Practical Power Delivery Systems
IEEE Access, 2020 Concepts of apparent power and power factor as measures of a system's power delivery capability are over a century old but have not been defined in one general, rigorous and acceptable way.

Rock breaking performance of the newly proposed unsubmerged cavitating abrasive waterjet
International Journal of Mining Science and Technology, 2023 To improve the rock breaking ability, cavitating waterjet and abrasive waterjet are combined by using a coaxial low-speed waterjet generated around the periphery of a high-speed abrasive waterjet, and a new type of waterjet called unsubmerged cavitating ...

Grounding theories of powers [PDF]
Synthese, 2020 AbstractNecessitarianism, as we shall use the term, is the view that natural properties and causal powers are necessarily connected in some way. In recent decades the most popular forms of necessitarianism have been the anti-Humean powers-based theories of properties, such as dispositional essentialism and the identity theory.
