Correction-Efficiency-Coefficient-Based Trajectory Optimization for Two-Dimensional Trajectory Correction Projectile

open access: yesAerospace, 2022
Based on the lift-to-drag ratio of a two-dimensional trajectory correction projectile, in this paper, a novel correction efficiency coefficient model has been proposed for the trajectory optimization of a two-dimensional trajectory correction projectile,

Correction coefficient for see-through labyrinth seal [PDF]

open access: yesEPJ Web of Conferences, 2017
In a steam turbine design, the flow-part design and blade shapes are influenced by the design mass-flow through each turbine stage. If it would be possible to predict this mass-flow more precisely, it will result in optimized design and therefore an ...

Finding coefficients for correction of potential value of wood assortments in real on the example of beech from thinning cuts in Serbia [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2021
Calculating the value of wood in forests has always been a job full of challenges for the appraiser, especially if in that case the condition is not to cut down trees. As one of the possibilities, the method of "model" cutting can be used, which

A high-precision correction method in non-rigid 3D motion poses reconstruction

open access: yesConnection Science, 2022
Occlusion, rotation and other factors affect human motion structure because of the incomplete acquired image sequence, resulting in poor performance of non-rigid three-dimensional (3D) motion pose reconstruction.
