In this study, we compute simplicial cohomology groups with different coefficients of a connected sum of certain minimal simple surfaces by using the universal coefficient theorem for cohomology groups. The method used in this paper is a different way to compute digital cohomology groups of minimal simple surfaces. We also prove some theorems related to degree properties of a map on digital sph...
Objective: When none of digital systems and scanners is accessible and it is essential to have digitized images of conventional radiographs, digital cameras can be used. The Aim of this study was to investigate whether digital images obtained by different resolutions of a digital camera are matched to the original radiographs in evaluation of caries. Methods: In this diagnostic accuracy in v...
Background and Aim: Instagram content is of concerns to business owners today. Nevertheless, the central problem in the production of Instagram content is not just writing a text. But how the audience conveys and comprehends it. This article aims to provide a digital content marketing model for Instagram bloggers. Research Method: This is an applied mixed research (quantitative and qualitative)...
Purpose: Study aimed to identify the applications of data mining in the provision of services, collection and management of digital libraries. Methodology: This is an applied study in terms of purpose and in terms of method is qualitative research that have been done by systematic review method. For this purpose, articles have been obtained by searching databases of Springer, Emerald, ProQuest,...
Abstract Background and purpose: Extensive application of x-ray as a diagnostic tool has created a global concern. Repeating a radiograph doubles radiation dose to the patient and staff. It was expected that development of digital facilities could decrease the rate of re-take of radiographs. The aim of this study was to investigate the causes for repeating digital panoramic radiographs. Mat...
BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...
Background and Aims: Conventional radiological equipments in our country are going to be converted to digital system using computed radiology (CR) technology. If we know the accuracy of digital panoramic radiography for detection of small defects in tooth, it will be useful in cases with difficulty for taking the intraoral radiographs. The aim of this study was to evaluate sensitivity and speci...
Purpose: Concerning digital libraries, interaction between user and system is among major issues for using library software. Therefore, finding appropriate software for this purpose is of high importance. This study aims to evaluate and analyze the criteria related to user interface in Farsi web pages of self-made and purchased digital libraries in Iran. Methodology: This is an applied and eva...
introduction: radiography is one of the most important diagnostic methods for evaluation of dental caries. on the other hand, the least amount of radiation along with high quality is a main gold standard. the purpose of this study was to compare the diagnostic accuracy of primax, insight radiographic films, and direct digital images (schick cmos-aps), in detection of interproximal natural carie...
