One-dimensional vs. two-dimensional based features: Plant identification approach

Two - vs . Three - Dimensional Object - Based Video

This paper compares 2-D and 3-D object modeling in terms of their capabilities and performance (peak-signal-to-noise-ratio and visual image quality) for very low bitrate video coding. We show that 2-D object-based coding with aane/perspective transformations and triangular mesh models can simulate almost all capabilities of 3-D object-based approaches using wireframe models at a fraction of the...

One- Vs Two- or Three-dimensional Effects in Sedimentary Valleys

This study of the effects of local geological conditions on seismic ground motion uses 1D amplification as a reference point and examines, via simple theoretical and more realistic numerical examples and observations, how 2D and 3D conditions differ from 1D estimations. Because 1D simulations cannot model basin and edge effects, 1D response tends, in general, to exhibit lower peaks and be of sh...

One - dimensional versus two - dimensional dynamics Sebastian

one and two dimensional ultrasonic vibration tool

this research is carried out to design and manufacturing of lathe vibration tool and their tests. firstly, one-dimensional vibration tool is designed and made of the bending vibration mode. one-dimensional vibration tool with half piezoelectric rings is considered to excite the bending mode of tool. structure of vibration tool is designed in abaqus software about 20 khz and then is made with re...
