today radiology and imaging are the only and main method to generate geometrical data from body. 3d model of the body will give us the best and reliable information for better understanding and diagnostic. on the other hand with development of cad/cam and rapid prototyping, the 3d printers were born to build 3d models without considering the geometry. today the 3d printers are able to makes a 3...

The purpose of this study was to investigate the effect of the reactive dye structure and type of penetrant in ink formulation on paper ink-jet printing. Different type of papers, which have same grammage was printed upon with three commercial reactive dyes, CI Reactive Blue 49 Ink 1, 4, CI Reactive Blue 21 Ink 2, Ink 5 and CI Reactive Blue 19 Ink 3, Ink 6, which are based on different reactive...

Reconstruction the spectral data of color samples using conventional color devices such as a digital camera or scanner is always of interest. Nowadays, multispectral imaging has introduced a feasible method to estimate the spectral reflectance of the images utilizing more than three-channel imaging. The goal of this study is to spectrally characterize a color scanner using a set of conventional...

In this paper we discuss the main features of the Residence Times Difference Fluxgate Magnetometer. A low-cost technology, negligible onboard power requirements and the intrinsic digital form of the readout signal are the main advantages of the proposed strategy. Results obtained show the possibility to realise low-cost devices exploiting Printed Circuit Board (PCB) technology for applications ...

This paper presents, a hybrid method, low-resolution and high-resolution, for Persian page segmentation. In the low-resolution page segmentation, a pyramidal image structure is constructed for multiscale analysis and segments document image to a set of regions. By high-resolution page segmentation, by connected components analysis, each region is segmented to homogeneous regions and identifyi...

To reduce the risk of spread of the novel coronavirus (COVID-19), the emerging protocols are advising for less physicianpatientcontact, shortening the contact time, and keeping a safe distance. It is recommended that unnecessary castingbe avoided in the events that alternative methods can be applied such as in stable ankle fractures, and hindfoot/midfoot/forefoot injuries. Fib...
