Video traces contain information about encoded video frames, such as frame sizes and qualities, and provide a convenient method to conduct multimedia networking research. Although widely used in networking research, these traces do not allow to determine the video quality in an accurate manner after networking transport that includes losses and delays. In this work, we provide (i) an overview o...

the purpose of velocity analysis is to extract the normal moveout velocity as a function of the zero-offset travel time at selected cdp locations along the seismic line. since results of velocity analysis depend on coherency estimator, an estimator that provides a high velocity resolution is essential. even though the conventional semblance method which is the most popular coherency estimator (...

due to some difficulties during seismic data acquisition, like natural obstacles (high voltage electricity cable, bad coupling of geophones with the ground) some of the traces cannot be recorded. since bad traces make the final stack unclear, usually bad traces go mute while processing. the final image of the earth’s crust is highly dependent of the quality and resolution of acquired data and m...

the present paper investigates how far ideologies can be tease out in discourse by examining the employed schemata by two ideologically opposed news media, the bbc and press tv, to report syria crisis during a period of nine months in 2011. by assuming that news is not a valuefree construction of facts and drawing on micro structural approach of schema theory, for the first time in discours...

the application of nmo (normal moveout) has been recognized as an effective method of generating quasi-zero-offset traces in traditional common-midpoint processing. artifacts of the nmo method relate to the nmo-stretch effects. conventional application of normal-moveout correction to a common-midpoint (cmp) reflection generates a stretch that increases with offset and decreases with zero-offset...
