Effect of Void Defects on the Indentation Behavior of Ni/Ni3Al Crystal

open access: yesNanomaterials, 2023
Inconel 718 (IN 718) superalloys are widely used as engineering materials owing to their superior mechanical performance. And voids are unavoidable defects in IN 718 superalloy preparation, which dramatically affect the mechanical properties of IN 718 ...

Calculation of wear (f.i. wear modulus) in the plastic cup of a hip joint prosthesis [PDF]

open access: yes, 1975
The wear equation is applied to the wear process in a hip joint prosthesis and a wear modulus is defined. The sliding distance, wear modulus, wear volume, wear area, contact angle and the maximum normal stress were calculated and the theoretical ...

The problem of the Pleiades distance. Constraints from Stromgren photometry of nearby field stars [PDF]

open access: yes, 2001
The discrepancy between the Pleiades cluster distance based on Hipparcos parallaxes and main sequence fitting is investigated on the basis of Stromgren photometry of F-type stars.

51 Tauri and the Hyades distance modulus

open access: yesThe Astrophysical Journal, 1988
Une nouvelle relation masse luminosite s'appuyant sur l'etude de l'etoile binaire spectroscopique 51 Tau est proposee pour l'amas des Hyades. De nombreuses binaires visuelles sont considerees pour etablir de nouvelles estimations de leurs elements orbitaux et de leurs masses.

Computation Method for the Settlement of a Vertically Loaded Pile in Sloping Ground

open access: yesAdvances in Civil Engineering, 2020
Based on the hyperbolic curve tangent modulus method and the wedge stress theory, this paper proposes a calculation method for the settlement of a vertically loaded single pile in sloping ground.

Fault Location of the Renewable Energy Sources Connected Distribution Networks Based on Time Differences of the Modal Traveling Waves

open access: yesIEEE Access, 2023
The topology of the distribution network and direction of the power flow will change when distributed generators (DGs) are connected to it, making it difficult to locate faults using conventional techniques like the impedance approach.

(In)stability of de Sitter vacuum in light of distance conjecture and emergence proposal

open access: yesJournal of High Energy Physics, 2023
The distance conjecture claims that as the modulus traverses along the trans-Planckian geodesic distance, the effective field theory becomes invalid by a descent of a tower of states from UV.

Distance between a Maximum Modulus Point and Zero Set of an Entire Function [PDF]

open access: yesComplex Variables, Theory and Application: An International Journal, 2003
Let f be an entire function of finite positive order. A maximum modulus point is a point w such that |f(w)|= max {|f(z)|:|z=|w|}. We obtain lower bounds for the distance between a maximum modulus point w and the zero set of f. These bounds are valid for all sufficiently large values of |w|.

The Optical Gravitational Lensing Experiment. Short Distance Scale to the LMC [PDF]

open access: yes, 1998
We present {\it UBVI} photometry of the eclipsing binary HV2274 - the system which has been recently used for distance determination to the LMC by Guinan et al. (1998).

Padé Approximant and Minimax Rational Approximation in Standard Cosmology

open access: yesGalaxies, 2016
The luminosity distance in the standard cosmology as given by ΛCDM and, consequently, the distance modulus for supernovae can be defined by the Padé approximant.
