We present the design, manufacturing, and dynamical characterization of a mechanical suspension made by passive magnetic spring an eddy current damper integrated into single device. Three configurations with 2, 3, 4 permanent magnets axially distributed opposite polarizations are designed, simulated, manufactured, tested. Stiffness 2410, 2050, 2090 N/m damping coefficient 5.45, 10.52 17.25 Ns/m...

We completely determine those natural numbers $n$ for which the full matrix ring $M_n(F_2)$ and triangular $T_n(F_2)$ over two elements field $F_2$ are either n-torsion clean or almost clean, respectively. These results somewhat address settle a question, recently posed by Danchev-Matczuk in Contemp. Math. (2019) as well they supply more precise aspect nil-cleanness property of $n\times n$ all ...

Let R be a commutative ring with multiplicative identity and C coassociative counital R-coalgebra the α-condition. A clean comodules defined based on cleanness rings modules. C-comodule M is comodule if endomorphism of clean. over itself i.e., as For an idempotent e ∈ R, there are relations between eRe R. It’s motivated us to investigate this condition for coalgebra. any C, we can construct ⇀C↼...

The rare processes K → πνν̄ and KL → π νν̄ play an outstanding role in the field of flavorchanging-neutral-current transitions. The main reason for this is their unmatched theoretical cleanness and their large sensitivity to short-distance (SD) effects arising in the standard model (SM) and its innumerable extensions. As they offer a precise determination of the unitarity triangle (UT) , a compar...

Listeners may be able to recognise speech in adverse conditions by “glimpsing” time-frequency regions where the target speech is dominant. Previous computational attempts to identify such regions have been source-driven, using primitive cues. This paper describes a model-driven approach in which the likelihood of spectro-temporal patches of a noisy mixture representing speech is given by a gene...
