background: driver fatigue is one of the major implications in transportation safety and accounted for up to 40% of road accidents. this study aimed to analyze the eeg alpha power changes in partially sleep-deprived drivers while performing a simulated driving task. methods: twelve healthy male car drivers participated in an overnight study. continuous eeg and eog records were taken during driv...
leiomyoma is a rare esophageal tumor that constitutes less than 1% of esophageal malignancies. it should be removed when diagnosed even if asymptomatic. this study presents two cases of esophageal leiomyoma in 38 and 62 years old men who presented with dysphagia and evaluated for diagnosis and location of related tumors. patients were clinically examined and upper gastrointestinal endoscopy, ch...
A rate control algorithm at the group of picture (GOP) level is proposed in this paper for variable bit rate applications of the H.265/HEVC video coding standard with buffer constraint. Due to structural changes in the HEVC compared to the previous standards, new rate control algorithms are needed to be designed. In the proposed algorithm, quantization parameter (QP) of each GOP is obtained by ...
In order to enhance the accuracy of the motion vector (MV) estimation and also reduce the error propagation issue during the estimation, in this paper, a new adaptive error concealment (EC) approach is proposed based on the information extracted from the video scene. In this regard, the motion information of the video scene around the degraded MB is first analyzed to estimate the motion type of...
The present paper is intended to present a robust multiplicative video watermarking scheme. In this regard, the video signal is segmented into 3-D blocks like cubes, and then, the 3-D wavelet transform is applied to each block. The low frequency components of the wavelet coefficients are then used for data embedding to make the process robust against both malicious and unintentional attacks. Th...
Objective: To determine the effectiveness of Transcranial Direct Current Stimulation (tDCS) in contrast with video game on executive function in children with Attention Deficit Hyperactivity Children (ADHD). Methodology: This study was an unblinded Randomized Control Trial with ADHD participants recruited from various schools of Patiala District in Punjab, India. Participants were screened fo...
Introduction: Adherence to diet in dialysis patients is one of the important care challenges that affect the quality of life. Education can change behavior by changing the level of awareness, attitude, and practice. Therefore, this study aimed to compare the effect of face-to-face and video-based diet training on the quality of life of patients undergoing hemodialysis. Methods: This study is a ...
BACKGROUND AND AIM: Poor oral health among children with impaired hearing has been reported frequently due to lack of communication skills and effective health educations. In this study, we assessed the effect of two training methods on short-term oral health outcomes among children with impaired hearing.METHODS: In this experimental study, 80 hearing impairment (HI) student aged 7-19 years old...
Introduction: Laryngeal dysfunction may be divided into three categories; organic, neurologic and functional disorders. Dysphonia and hoarseness are the most common symptoms and, in some cases, the only signs of laryngeal dysfunction. In differential diagnosis of any type of chronic hoarseness, a neoplastic process must be considered and, thus continuous light video laryngoscopy can provide imp...
Introduction: There are methodological challenges on the subject of communication skills training despite general agreement on its advantages. This study was performed to compare the effect of communication skills training through video feedback with the usual method of lecture. Methods: This quasi-experimental double-blind prospective study was performed on two groups of 20 interns in the ye...
