This paper presents a novel method to fabricate the horizontal frustum structure as a planar optical waveguide by using the proximity printing technique. A horizontal frustum optical waveguide with a both lateral and vertical taper structure was produced. The orthogonal and inclined masks with the diffraction effect were employed in lithography process. This method can precisely control each ho...

in this research, papaya slices with dimensions of 0.5×2×5 cm3 were dried at 45 °c using a cabinet dryer in which drying air velocity and relative humidity were 0.9 m/s and 30%, respectively. the moisture diffusion coefficient of papaya was determined in this drying condition. mass transfer equation with its boundary conditions was solved based on finite difference method. finally, coefficient ...

A method is presented for interpolation between neighbouring slices in a grey-scale tomographic data set, when a high-resolution image of the same patient is also available. Spatial correspondence between adjacent slices in the high-resolution image are established using a voxel-based non-rigid registration algorithm. These spatial correspondences are used to calculate a set of vectors, which a...

Let n be an odd integer greater than 1. We slice a circular pizza into 2n slices, making cuts from non-central interior point of the circle. estimate difference between total area even numbered slices and slices.

Data warehousing gives frameworks and means for enterprise administrators to methodically prepare, comprehend, utilize the data improve strategic decision-making skills. One of principal challenges warehouse designers is fragmentation. Currently, several fragmentation approaches warehouses have been developed since this technique can decrease OLAP (online analytical processing) query response t...

a fundamental assumption in prosthetic dentistry is that the axis-orbital plane will usually be parallel to the horizontal reference plane. most articulator systems have incorporated this concept into their designs and use orbitale as the anterior reference point for transferring the vertical position of the maxilla to the articulator. clinical observations of cantonese patients suggest that in...

In this paper, we propose a robust method to register a panoramic range data obtained by a panoramic laser range finder and an omni-directional image acquired by a stereo omni-directional system (SOS), by matching the horizontal and vertical edge histograms of the two images. The proposed method first estimates the relative horizontal rotation angle by matching the vertical edge histograms. Nex...

In this paper the application of edge detection techniques to gravity data are described. Edge enhancement in potential-field data helps geologic interpretation. There exist several methods for enhancing edges, such as tilt angle, and the derivative of tilt angle. Most of these methods are high-pass filters based on the horizontal or vertical derivatives of the field. To determine the filters n...

Artifacts arising when differential phase images are integrated is a common problem to several X-ray phase-based experimental techniques. The combination of noise and insufficient sampling the high-frequency signal leads formation streak artifacts in projections, translating into poor image quality tomography slices. In this work, we apply non-iterative integration algorithm proven reduce plana...
