The determination of the outher shape of object “C” lower ceiling in the VŠB-TU Ostrava [PDF]

open access: yesActa Montanistica Slovaca, 2005
The paper deals with the measurement of the conical shape of lower ceiling by the total station Leica TCR307 and with the evaluation for its reconstruction. The 3D coordinates of the upper and lower border of the conical surface are calculated.

Gravity duals of boundary cones [PDF]

open access: yes, 2016
The replica trick defines Renyi entropies as partition functions on conically singular geometries. We discuss their gravity duals: regular bulk solutions to the Einstein equations inducing conically singular metrics at the boundary.

Ultrasonic Lapping of Conical Surfaces

open access: yesJournal of the Japan Society of Precision Engineering, 1978
超音波縦振動を付加した円すい面のラッピング実験の結果,次のことがわかった.(1)超音波振動を付加させると,ラップ量を増やすことができる.この振動によるラップ量の増加効果は振動速度と回転速度との比で決まり,この比が大きくなると大きくなる.(2)超音波振動を付加させると,ラップ抵抗を減少させることができる.この振動によるラップ抵抗の減少効果は,振動速度と回転速度との比で決まり,この比が大きくなると大きくなる.(3)仕上面粗さは適切な振動速度と回転速度の条件で超音波振動ラッピングを行うと向上させることができる.

Conical Statistical Optimal Near-Field Acoustic Holography with Combined Regularization

open access: yesSensors, 2021
For the sound field reconstruction of large conical surfaces, current statistical optimal near-field acoustic holography (SONAH) methods have relatively poor applicability and low accuracy.

Spectral transitions for Aharonov-Bohm Laplacians on conical layers [PDF]

open access: yes, 2016
We consider the Laplace operator in a tubular neighbourhood of a conical surface of revolution, subject to an Aharonov-Bohm magnetic field supported on the axis of symmetry and Dirichlet boundary conditions on the boundary of the domain.

Bi-Lipschitz geometry of weighted homogeneous surface singularities

open access: yes, 2007
We show that a weighted homogeneous complex surface singularity is metrically conical (i.e., bi-Lipschitz equivalent to a metric cone) only if its two lowest weights are equal.

Optimizing Post Friction Stir Welding Heat Treatment in Dissimilar Friction Stir Welded 6061/AlSi10MgMn Joints for Electrical Vehicle Battery Housing

open access: yesAdvanced Engineering Materials, EarlyView.
Microstructural evolution and hardness optimization along the cross‐section of friction stir welded AA6061/AlSi10MgMn joints, for electric vehicle battery housings, were investigated. Postweld aging between 170°C and 220°C enhances hardness uniformity within the nugget zone.
