Three-Parameter P-S-N Curve Fitting Based on Improved Maximum Likelihood Estimation Method

open access: yesProcesses, 2023
The P-S-N curve is a vital tool for dealing with fatigue life analysis, and its fitting under the condition of small samples is always concerned. In the view that the three parameters of the P-S-N curve equation can better describe the relationship between stress and fatigue life in the middle- and long-life range, this paper proposes an improved ...

On Serre's uniformity conjecture for semistable elliptic curves over totally real fields [PDF]

open access: yes, 2015
Let $K$ be a totally real field, and let $S$ be a finite set of non-archimedean places of $K$. It follows from the work of Merel, Momose and David that there is a constant $B_{K,S}$ so that if $E$ is an elliptic curve defined over $K$, semistable outside

Acoustic radiation force impulse imaging for noninvasive evaluation of renal parenchyma elasticity: preliminary findings. [PDF]

open access: yesPLoS ONE, 2013
OBJECTIVE: To evaluate the diagnostic value of acoustic radiation force impulse (ARFI) to test the elasticity of renal parenchyma by measuring the shear wave velocity (SWV) which might be used to detect chronic kidney disease (CKD).

Large N Duality, Lens Spaces and the Chern-Simons Matrix Model [PDF]

open access: yes, 2003
We demonsrate that the spectral curve of the matrix model for Chern-Simons theory on the Lens space S^{3}/\ZZ_p is precisely the Riemann surface which appears in the mirror to the blownup, orbifolded conifold.

Fast Fencing [PDF]

open access: yes, 2018
We consider very natural "fence enclosure" problems studied by Capoyleas, Rote, and Woeginger and Arkin, Khuller, and Mitchell in the early 90s. Given a set $S$ of $n$ points in the plane, we aim at finding a set of closed curves such that (1) each point

The value of dual-energy spectral CT in differentiating solitary pulmonary tuberculosis and solitary lung adenocarcinoma

open access: yesFrontiers in Oncology, 2022
BackgroundTo explore the value of dual-energy spectral CT in distinguishing solitary pulmonary tuberculosis (SP-TB) from solitary lung adenocarcinoma (S-LUAD).MethodsA total of 246 patients confirmed SP-TB (n = 86) or S-LUAD (n = 160) were ...

Minimal decomposition of binary forms with respect to tangential projections [PDF]

open access: yes, 2010
Let $C\subset \mathbb{P}^n$ be a rational normal curve and let $\ell_O:\mathbb{P}^{n+1}\dashrightarrow \mathbb{P}^n$ be any tangential projection form a point $O\in T_AC$ where $A\in C$.

RESEARCH ON BENDING FATIGUE TEST BASED ON 42CRMO GEAR (MT)

open access: yesJixie qiangdu, 2023
42CrMo is a kind of ultra-high strength steel, which has high strength, good hardenability and small deformation after quenching. It is widely used in driving materials such as large gears, bearing spindle and connecting rod used in traction.

On Chow Stability for algebraic curves [PDF]

open access: yes, 2015
In the last decades there have been introduced different concepts of stability for projective varieties. In this paper we give a natural and intrinsic criterion of the Chow, and Hilbert, stability for complex irreducible smooth projective curves $C ...
