Torque calculation of five-phase synchronous reluctance motors with shifted-asymmetrical-salient-poles under saturation condition

open access: yesCES Transactions on Electrical Machines and Systems, 2020
In traditional analytical method (AM), the magnetic saturation is always ignored to simplify the calculation process. However, synchronous reluctance motors (SynRMs) often operate around saturation point to achieve higher torque density. Therefore, a new

On saturation games

open access: yesEuropean Journal of Combinatorics, 2016
A graph $G = (V,E)$ is said to be saturated with respect to a monotone increasing graph property ${\mathcal P}$, if $G \notin {\mathcal P}$ but $G \cup \{e\} \in {\mathcal P}$ for every $e \in \binom{V}{2} \setminus E$. The saturation game $(n, {\mathcal P})$ is played as follows.

Consensus With Output Saturations [PDF]

open access: yesIEEE Transactions on Automatic Control, 2017
This paper consider a standard consensus algorithm under output saturations. In the presence of output saturations, global consensus can not be realized due to the existence of stable, unachievable equilibrium points for the consensus. Therefore, this paper investigates necessary and sufficient initial conditions for the achievement of consensus, that ...

Superficial Saturation [PDF]

open access: yesTokyo Journal of Mathematics, 1986
For a Cohen-Macaulay semi-local ring A of dimension \(d=1\) a stable ideal I of definition has the equivalent properties \((i)\quad \lambda (A/I^ n)\) \((\lambda =length)\) is a polynomial for all \(n>0\), \((ii)\quad xI=I^ 2\) for some \(x\in I\) [see \textit{J. Lipman}, Am. J. Math. 93, 649-685 (1971; Zbl 0228.13008)].

Numerical Simulation Of The Treatment Of Soil Swelling Using Grid Geocell Columns

open access: yesSlovak Journal of Civil Engineering, 2015
In this paper, a method for the treatment of the swelling of expansive soil is numerically simulated. The method is simply based on the embedment of a geogrid (or a geomesh) in the soil.

Generic saturation

open access: yesJournal of Symbolic Logic, 1998
Assuming that ORD is ω + ω-Erdös we show that if a class forcing amenable to L (an L-forcing) has a generic then it has one definable in a set-generic extension of L[O#]. In fact we may choose such a generic to be periodic in the sense that it preserve the indiscernibility of a final segment of a periodic subclass of the Silver indiscernibles, and ...
