Three Dimensional Refraction Methods

specialized methods to teach spelling: comparing three methods

چکیده: بررسی ادبیات مربوطه در کشور در زمینه یادگیری زبان انگلیسی نشان می‎دهد که علی‎رغم اهمیت املا در فرآیند یادگیری به طور عام و یادگیری زبان انگلیسی به طور خاص، این مولفه از جایگاهی متناسب با اهمیت آن برخوردار نیست و عمدتاً نادیده گرفته شده است. تحقیقات گسترده‎ای در خارج از کشور در مورد ماهیت این مولفه صورت گرفته است، در حالی که به جرأت می‎توان گفت در داخل کشور گامی در مورد درک ماهیت آن و فرآی...

Stereoscopic three-dimensional television using active glasses with switchable refraction

We have devised a full-resolution stereoscopic television system incorporating both a patterned retarder and active glasses. Selective vision of the left image by the left eye and the right image by the right eye is achieved by a conventional combination of a patterned retarder and left and right polarized filters. Full resolution is provided by the active components of the glasses acting as a ...

Negative refraction in three-dimensional point-dipolelike polaritonic crystals

We propose two practical realizations of the point-dipole crystal, shown previously to be capable of negative refraction and other metamaterial and plasmonic properties. These are: an array of highly polarizable spheres, and the complementary array of spherical cavities in a highly polarizable medium. We study light propagation through these polaritonic crystals and show that they are capable o...

Methods For Analyzing Three Dimensional Scenes

Several methods f o r analyzing three dimensional scenes are discussed w i t h respect to t h e i r advantages and d i f f i c u l t i e s i n g e t t i n g r e a l three d i mensional coordinates.
