Arc Furnace Power-Susceptibility Coefficients
Energies, 2022 The article presents the susceptibility coefficients active power kp and reactive power kq, as proposed by the author. These coefficients reflect the reaction of arc furnaces (change of the furnace operating point) to supply voltage fluctuations. The considerations were based on the model of the arc device in which the electric arc was replaced with a ...

Computational Optimization of Adaptive Hybrid Darrieus Turbine: Part 1
Fluids, 2019 Darrieus-type Vertical Axis Wind Turbines (VAWT) are promising for small scale decentralized power generation because of their unique advantages such as simple design, insensitive to wind direction, reliability, and ease of maintenance.

ON NILPOTENT POWER SERIES WITH NILPOTENT COEFFICIENTS [PDF]
Korean Journal of Mathematics, 2013 Summary: Antoine studied conditions which are connected to the question of Amitsur of whether or not a polynomial ring over a nil ring is nil, introducing the notion of nil-Armendariz rings. Hizem extended the nil-Armendariz property for polynomial rings onto power-series rings, say nil power-serieswise rings.

Power series with almost periodic coefficients [PDF]
Proceedings of the American Mathematical Society, 1967 and that the corresponding limit at x = e(O), where 0 is not congruent (mod 1) to an integral multiple of a, is zero. P. Sziisz has pointed out that for the proof of (1) and (2) Davenport's conditions can be reduced to the following: (a) limN_. EInIN ane(nt) exist for each real t, and (b) I E jnI,N a.e(nt) I

Advanced design and optimization of wind turbines based on turbine theories [PDF]
, 2019 A review of wind turbine technology showed that many flaws in both the flow models and computations are involved in the traditional fundamentals. While traditional methods for design and computation are all based on the airfoil theory, a new method based
