Ophthalmic method and apparatus [PDF]

, 1973
A method and apparatus for removing material and components such as the lens from an eye is described. High speed rotary cutting members at one end of a rod macerate the lens while an annular tubing disposed around the cutting members vibrates ...

Interaction Mechanisms between Blades and Maize Root–Soil Composites as Affected by Key Factors: An Experimental Analysis

Agriculture
To design a high-performance stubble-breaking device, studying the interaction mechanisms between blades and root–soil composites is urgent. A simplified experimental method was proposed to investigate the cutting process and the effects of key factors ...

Mathematical modeling of vibration resistance of long turning of slender parts

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение
This paper is devoted to mathematical modeling of vibration-resistant machining of low-rigidity parts. The relevance of this research stems from the occurrence of significant vibrations in the workpiece during machining on a metal-cutting machine.

Optic flow based perception of two-dimensional trajectories and the effects of a single landmark. [PDF]

, 2001
It is well established that human observers can detect their heading direction on a very short time scale on the basis of optic flow (500ms; Hooge et al., 2000). Can they also integrate these perceptions over time to reconstruct a 2D trajectory simulated

A map and a pipe : a new approach to characterizing erosion-corrosion regimes of Fe in three dimensions using CFD modelling [PDF]

, 2009
In studies of erosion-corrosion, much work has been carried out in recent years to identify regimes of behaviour. Such regimes describe the transition between the erosion and corrosion dominated mechanisms.
