It is characterized by four morphological features, large malalignment ventricular septal defect, Pulmonary stenosis, Overriding of aorta, and Right ventricular hypertrophy. The infant with TOF does well for the first few months of life with minimal or no cyanosis. The cyanosis begins to increase with secondary slow increase in polycythemia as well. Hypercyanotic spells are the most common complicating features of TOF
Patients and methods: This is a retrospective study of 200 patients with Tetralogy of Fallot (TOF) referred to Ibn Al-Bitar Center for Car

A robust video-bitrate adaptive scheme at client-aspect plays a significant role in keeping a good quality of video streaming technology experience. Video quality affects the amount of time the video has turned off playing due to the unfilled buffer state. Therefore to maintain a video streaming continuously with smooth bandwidth fluctuation, a video buffer structure based on adapting the video bitrate is considered in this work. Initially, the video buffer structure is formulated as an optimal control-theoretic problem that combines both video bitrate and video buffer feedback signals. While protecting the video buffer occupancy from exceeding the limited operating level can provide continuous video str
