Experimental study on dynamic mechanical behavior of frozen sandstone with different saturations

open access: yesMeitan kexue jishu, 2023
Water content is one of the critical factors affecting frost damage to rock masses in alpine regions. A dynamic disturbance load further complicates the issue.

Sub-domain Model for Induction Motor with More Accurate Realization of Tooth-Saturation

open access: yes, 2023
Incorporation of magnetic saturation and its aftereffects have been challenging for sub-domain based analytical electric motor models. The proposed model utilizes the direct phenomenal impact of magnetic saturation on spatial variation of the core's ...

The Saturation of the Response to an Electron Beam of Ce- and Tb-Doped GYAGG Phosphors for Indirect β-Voltaics

open access: yesApplied Sciences, 2023
GYAGG:Tb (Ce) scintillators have been confirmed to be promising sources of light emission when excited by an intense 150 keV electron beam. The saturation of the scintillation yield under such excitation conditions has been studied.

Impact of cross-saturation in sensorless control of transverse-laminated synchronous reluctance motors [PDF]

open access: yes, 2006
Synchronous reluctance (SyR) motors are well suited to a zero-speed sensorless control, because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based on the ...

Relativistic Persistent Currents in Ideal Aharonov-Bohm Rings and Cylinders

open access: yesAnnals of West University of Timisoara: Physics, 2016
In this report we revisit the results obtained in [1, 2] where the relativistic Aharonov-Bohm was studied for the first time. The method is based on the exact solutions of the complete (1+3)-dimensional Dirac equation of fermions moving in ideal Aharonov-

ANALYSIS OF POROSITE-NEUTRON (NPHI) LOGGING DATA FROM THE KINKASI FIELD: THE CASE OF THE G UP, F AND E HORIZONS OF THE CENOMANIAN RESERVOIR (D.R. CONGO COASTAL BASIN) [PDF]

open access: yesRomanian Journal of Petroleum & Gas Technology
Since the discovery of hydrocarbon deposits in the DR Congo Coastal Basin in general, and in the Kinkasi field in particular, several development wells have been drilled with a view to optimising the economic value of the reserves evaluated.

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.
