Rapid advances in observational cosmology have led to the establishment of a precision cosmological model, with many of the key cosmological parameters determined to one or two significant figure accuracy. Particularly prominent are measurements of cosmic microwave background (CMB) anisotropies, led by the seven-year results from the Wilkinson Microwave Anisotropy Probe (WMAP) [1–3]. However th...
Many years ago various new concepts have been introduced into Isabelle to support the Isar proof language. While the original motivation was coming from the demands of human-readable proof texts, most of this infrastructure has turned out as generally useful in building other advanced mechanisms. So today “Isar” concepts already permeate large parts of Isabelle, enabling simpler and more powerf...
در این تحقیق مدل‌سازی عددی رسوب‌شویی در مخزن سد سفیدرود و تأثیر آن در احیای حجم مخزن در کوتاه مدت و بلند مدت مورد بررسی قرار گرفته است. بدین منظور از مدل عددی GSTARS 3 برای بررسی فازهای مختلف فلاشینگ استفاده شده است. این مدل برای رسوب‌شویی آزاد و تحت فشار تهیه و هرکدام به طور مجزا مورد تجزیه و تحلیل قرار گرفته است. بررسی های انجام شده ب...
Today, people collect their personal multimedia content on home media servers. In addition to consuming their content on TV sets, people are using mobile multimedia players, PCs and even mobile phones. Since those terminals have various capabilities, it is necessary to adapt the content to a more device specific version. For audio, video, and graphics scalable codecs exist which realize this go...
To investigate the development of motion integration in infants, we used an eye movement technique to measure subjects' ability to track leftward versus rightward pattern motion in a stimulus consisting of a field of spatially segregated moving gratings. Each grating moved in one of two oblique directions, with the two directions interleaved across the display. When spatially integrated, patter...
