The concept of literacy has undergone a conceptual leap due to the constant growth of technology and the introduction of digital tools. Often-cited as an important component of modern literacy, digital literacy has received significant attention. Since the role of socio-demographic characteristics like gender, place of residence, access to digital tools, fields of study, level of university and...
Purpose: Digital library user interfaces has a determining role in desirable performance of this kind of libraries. Digital Library service providers to the blind and deaf users will have their best performance when the users (deaf and blind users) could have a proper interaction with them. This study aims to evaluate and analyze the criteria related to user interface in digital libraries servi...
Background and Objective: Nowadays, the use of digital devices such as televisions, DVDs, smartphones, tablets, and computer games is increasing among children. The present study was conducted with the aim of understanding the potential effects of the use of media in children. Instruments and Methods: In the present systematic review, domestic and International articles investigating the effec...
Recording the variation of joint angles as a feedback to the control unit is frequent in articulated arms. In this paper, magnetic sensor AS5045, which is a contactless encoder, is employed to measure joint angles of 6R robot and the performance of that is examined. The sensor has a low volume, two digital outputs and provides a high resolution measurement for users; furthermore its zero positi...

This study aims to investigate the attitude towards digital gap among students, and its relationship with educational progress and socio-economic status (SES) of university students at Alborz Uni...
Introduction: A study model is a precise three dimensional replica of patient’s dentition and plays an important role in treatment planning. Many digital multi-media applications have become available to the clinician and his or her staff to facilitate standard procedures in practice and management. The aim of this study is to evaluate reliability and validity of dental measurement made on dig...
Background and Aim: Interaction in a digital library help users locating and accessing information and also assist them in creating knowledge, better perception, problem solving and recognition of dimension of resources. This paper tries to identify and introduce the components and elements that are used in interaction between user and system in search and retrieval of information in digital li...
The aim of this paper is to compute a simplicial cohomology group of some specific digital images. Then we define ringand algebra structures of a digital cohomology with the cup product. Finally, we prove a special case of the Borsuk-Ulam theorem fordigital images.
Increasing interest is being shown in the use of microprocessor for protection, switching and data acquisition required in modern high voltage substations. One of the most difficult functions to fulfill is that of transmission line distance protection employing samples of the voltage and current waveform taken from high voltage transducer equipment at the usual relaying point. This paper examin...
