REFRACTION IN SCHOOLS.

Refraction in volume graphics

Refraction in Discrete Raytracing

Refraction is an important graphics feature for synthesizing photorealistic images. This paper presents a study on refraction rendering in volume graphics using discrete ray tracing. We describe four basic approaches for determining the relative refractive index at each sampling position, and examine their relative merits. We discuss two types of anomalies associated with some approaches and th...

the relationship between teaching styles and personality types of efl teachers in iranian schools

معلمان یکی از موثرترین عنصر برای موفقیت در هر سیستم آموزشی می باشند. این تحقیق? رابطه بین شخصیت معلمان و سبک های آموزشی شان را در محیط یادگیری زبان انگلیسی در ایران بررسی می کند. بهمین جهت? با توجه به موارد موجود? تعداد 45 نفر از معلمان زبان از مدارس مختلف تبریز انتخاب شدند. اطلاعات از طریق نوع شخصیت معلم و فهرستی از سبکهای آموزشی شان جمع آوری شد. تجزیه و تحلیل داده ها نشان داد که رابطه معنی دا...

Negative refraction in indefinite media

Initial experiments on wedge samples composed of isotropic metamaterials with simultaneously negative permittivity and permeability have indicated that electromagnetic radiation can be negatively refracted. In more recently reported experiments [Phys. Rev. Lett. 90, 1074011 (2003)], indefinite metamaterial samples, for which the permittivity and permeability tensors are negative along only cert...

Refraction in Full-term Babies.

Tim study of refraction in newborn infants may be helpful in understanding the incidence of refractive errors in later years. In this paper, the refractive conditions of 100 newborn infants are reported. Not much work on this subject has been done in the past. Sorsby, Benjamin, and Sheridan (1961) reported the refractive condition of the eyes in the age-group 2 to 23 years, and Hosaka (1963) ob...
