PREDICTION OF TITANIUM ALLOYS EROSIVE WEAR UNDER LONG-TERM DROPLET-IMPACT EFFECT

open access: yesAdvanced Engineering Research, 2011
The approximating model for the definition of the steam turbines blades wear rate under the continuous operation through the droplet-impact erosion is built on the ground of the comparative analysis of the stand test data of the titanium alloy samples.

Approximation of Any Particle Size Distribution Employing a Bidisperse One Based on Moment Matching

open access: yesColloids and Interfaces
Dispersed phases like colloidal particles and emulsions are characterized by their particle size distribution. Narrow distributions can be represented by the monodisperse distribution. However, this is not the case for broader distributions.

Nonlinear Nonnested Spline Approximation

open access: yes, 2017
Nonlinear approximation from regular piecewise polynomials (splines) supported on rings in R2 is studied. By definition, a ring is a set in R2 obtained by subtracting a compact convex set with polygonal boundary from another such a set, but without ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Accelerated Modeling of Transients in Electromagnetic Devices Based on Magnetoelectric Substitution Circuits

open access: yesEnergies
During switching in electrical systems, transient electromagnetic processes occur. The resulting dangerous current surges are best studied by computer simulation.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

FEATURES OF USE OF MONTE-CARLO METHOD FOR APPROXIMATION OF STATISTICAL DISTRIBUTIONS OF RESULTS OF NONLINEAR TRANSFORMATIONS IN RADAR-TRACKING PROBLEMS

open access: yesВесці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2017
An approach to the decision of mathematical problems with use of modelling random variables, the method which has received the name of Monte-Carlo is considered. The given method has got the greatest popularity for numerical calculation of high frequency

Systems of Approximating Functions when Using Variational Methods for Calculating Thin-Walled Building Structures

open access: yesStructural Mechanics of Engineering Constructions and Buildings
The question of the use of approximating functions in the calculation of thinwalled building structures is investigated and the requirements that they must satisfy are analyzed.

Iterative methods for the force-based quasicontinuum approximation : analysis of a 1D model problem [PDF]

open access: yes, 2011
Force-based atomistic-continuum hybrid methods are the only known pointwise consistent methods for coupling a general atomistic model to a finite-element continuum model.
