Introduction: Video games are common cultural issues with great influence in all societies. One of the important cognitive effects of video games is on creating stress on video players. The present research objective was to study different types of stress in players based on video game styles. Methods: A total of 80 players, aged 18 to 30 years, played four types of video games; Ru...
This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...
Aims: The aim of this study was to compare the effect of teach-back method and video clip teaching on the sense of coherence of mothers with children suffering from asthma. Materials & Methods: In this field trial study 75 eligible mothers with children suffering from asthma were selected by convenience sampling method, but were randomly divided into three groups of: video clip group, teach-ba...
Fiberoptic nasoendoscopy (FNE) is a powerful investigative tool in ear, nose, and throat practice in which its use in the management of epistaxis is varied among clinicians. The practice of assessing the nasal cavity after removal of nasal packs is common but its usefulness has not been evaluated. Therefore, we assessed the benefits of routine FNE after removal of nasal packs in epistaxis patie...
Recognition of visual events as a video analysis task has become popular in machine learning community. While the traditional approaches for detection of video events have been used for a long time, the recently evolved deep learning based methods have revolutionized this area. They have enabled event recognition systems to achieve detection rates which were not reachable by traditional approac...
Background: Autism spectrum disorder (ASD) is characterized by difficulty in the areas of social functioning, communication , and the presence of stereotypic and repetitive behaviors. Video modeling has been found to be an effective procedure for teaching a variety of skills to persons with autism.

the purpose of the present study was to compare the effects of two methods of self-modeling and video demonstration of an expert on the acquisition and retention of volleyball serve skill. participants were 30 students (aged between 12 and 14) who were assigned into two homogeneous groups after the pretest. the self-modeling group (n = 15) watched their performances in the criterion task via a ...
ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. h...
