Computer aided design and computer aided modeling tools are becoming increasingly important in the design and performance evaluation of communication systems. In this work, we report on the computer simulation modeling study of terrestrial digital microwave radio transmission, using Block Oriented System Simulator package (BOSS). The work concentrates on semi-analytical error rate evaluation in...

Background: The application of digital educational games in health professions education is on expansion and game-based education usage is increasing. Methods: Diverse databases were searched and the related papers were reviewed. Results: Considering the growing popularity of educational games in medical education, we attempted to classify their benefits, flaws, and engaging factors. Conclus...

Due to the expected increase of defects in circuits based on deep submicron technologies, reliability has become an important design criterion. Although different approaches have been developed to estimate reliability in digital circuits and some measuring concepts have been separately presented to reveal the quality of analog circuit reliability in the literature, there is a gap to estimate re...

The inkjet printing machine was initially used on ceramic parts as a small device in designing and advertising offices limitedly. In recent years, this device has been applied professionally to create high-quality patterns in the industry. In this method, liquid ceramic ink is sprayed on the specified parts by piezoelectric nozzles and after drying and discharging, the organic matter is baked a...

In wireless channel the noise has a zero mean. This channel property can be used in the enhancement of the noise performance in the digital receivers by oversampling the received signal and calculating the decision variable based on the time average of more than one sample of the received signal. The averaging process will reduce the effect of the noise in the decision variable that will approa...

the present research endeavors to discover similarities and differences among digital libraries in iran and to clarify the extent of their consistency in terms of main library requisites. using a qualitative -quantitative method, i.e. a survey research method using content analysis, it identifies iranian digital libraries (idls) and explores their characteristics. reviewing the literature, we i...

background radiographs play an integral role in the assessment of periodontal disease. in recent years, advent of digital imaging has revolutionized radiology in dentistry. patients and methods in this diagnostic accuracy study, 48 inter proximal surfaces were evaluated in eight patients. these patients had alveolar bone loss in anterior regions because of periodontitis. intraoral (parallel per...

Dual spacization of publishing means emergence of digital publishing in online and offline virtual environments along with analogue publishing. Analogue publishing is a kind of publishing that is produced in the form of physical printed writings as they appear in a single paper, single or many pages newspapers and magazines and books, writings on leaves and pieces of trees, natural skin and lea...
