Analysis of power parameters of combined three-direction deformation of parts with flange [PDF]

open access: yesFME Transactions, 2021
The upper bound power method is used to simulate the process of combined radial-backward-forward extrusion of hollow parts of the "cup with flange and branch pieces" type from a continuous workpiece.

Cosmic velocity fields and their interpretation [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
We review the current status of our knowledge of cosmic velocity fields, on both small and large scales. A new statistic is described that characterizes the incoherent, thermal component of the velocity field on scales less than 2 h −1 Mpc ( h

Combined prediction model of truck multi-section travel time in open-pit mine based on velocity field

open access: yesGong-kuang zidonghua, 2022
Due to the complexity of road in open-pit mine, the existing truck travel time prediction methods are difficult in the actual deployment. This leads to the truck optimal scheduling system only realizing scheduling instead of optimization.

Aspect angle dependence of the E region irregularity velocity at large flow angles [PDF]

open access: yes, 2007
We present the Doppler velocity observations of 1-m plasma waves in the auroral E region by the Scandinavian Twin Auroral Radar Experiment (STARE) Norway VHF coherent radar in the context of simultaneous and coincident measurements of electron and ion ...

Shrinking of Ischia Island (Italy) from Long-Term Geodetic Data: Implications for the Deflation Mechanisms of Resurgent Calderas and Their Relationships with Seismicity

open access: yesRemote Sensing, 2021
The identification of the mechanisms responsible for the deformation of calderas is of primary importance for our understanding of the dynamics of magmatic systems and the evaluation of volcanic hazards.

Exact solutions for the longitudinal flow of a generalized Maxwell fluid in a circular cylinder

open access: yesArchives of Mechanics, 2010
This paper deals with the longitudinal flow of a generalized Maxwell fluid in an infinite circular cylinder, due to the longitudinal variable time-dependent shear stress that is prescribed on the boundary of the cylinder. The fractional calculus approach

Isoscalar dipole response of heavy nuclei in low-energy region within kinetic model [PDF]

open access: yesЯдерна фізика та енергетика, 2020
The isoscalar dipole response of heavy spherical nuclei in the low-energy region is studied by using a semiclassical model, based on the solution of the linearized Vlasov kinetic equation for finite Fermi systems. In this translation-invariant model, the

Examining the Velocity field and the effects of hydraulic and geometrical parameters on the amount of the sediment entering the diversion channels through using Artificial Neural Network and ANSYS-CFX Software [PDF]

open access: yesمهندسی منابع آب, 2019
Intakes are one of the varied types of channel and river- water- intake structures. The experimental model is first simulated through ANSYS- CFX software. The verification results indicate that the results of the numerical model correspond fairly well to
