Polarisation-mode coupling in (100)-cut Nd:YAG

Optics Express, 2006
We investigate the polarisation-mode dynamics and Lamb's mode coupling constant for orthogonally polarised laser states in a dual-mode (100)-cut Nd:YAG laser with feedback, and compare with an anisotropic rate equation model. The anisotropic (100)-cut Nd:YAG exhibits thermally-induced depolarisation and polarisation-mode coupling dependent on the pump ...

Influence of cutting parameters and plasma cutting mode on cutting quality and process noise [PDF]

Manufacturing Technology, 2020
Plasma cutting is an ever-evolving method of industrial cutting of materials. Like all modern methods, it must meet the requirements for the quality of the cut, but also the hygiene and safety regulations set by European legislation. New ways are being sought to reduce process noise while improving the quality of the cutting surface.

Predictive plots for conical pick performance using mechanical and elastoplastic properties of rocks

Journal of Rock Mechanics and Geotechnical Engineering, 2020
Conical picks are by far the most widely used drag type cutting tools employed on partial face rock excavation machines. The cutting force and specific energy are two important design parameters for the conical pick performance, and the rock cutting ...

The mode of inheritance in tetraploid cut roses [PDF]

Theoretical and Applied Genetics, 2012
Tetraploid hybrid tea roses (Rosa hybrida) represent most of the commercial cultivars of cut roses and form the basis for breeding programmes. Due to intensive interspecific hybridizations, modern cut roses are complex tetraploids for which the mode of inheritance is not exactly known.
