It consists of three optical elements : the concave primary mirror‚ the diagonal or small flat mirror and the eyepiece or ocular‚ mounted in a tube. The primary mirror gathers light from astronomical objects and focuses it in its focal plane. The small flat mirror turns the image

the theme of illusion and reality through Othello’s illusions that his loving‚ caring‚ honest wife has committed adultery. These illusions are created by jealous Iago who plants seeds of uncertainty and doubt into Othello’s mind and turns his world upside down.

Abstract The military/aerospace platform operational environment challenges the creativity of fiber optic module packaging engineers as they endeavor to develop and mature new active and passive single-mode fiber optic and photonic components for next generation avionics networking applications. Low sales and manufacturing volumes inherent to avionics combined with lack of standard interface specifications for current and next generation fiber optic local area network architectures and sub-systems

Internet Infrastructure: Undersea Cables When thinking about where the internet lives‚ it would be plausible to think it lies among high-tech satellites communicating around the world simultaneously – resembling something of a digital cloud. Instead‚ the internet does not resemble a cloud‚ but instead resides in a physical infrastructure in hundreds of cables snaking underground and along the bottom of the sea. In fact‚ overseas satellite links currently account for only roughly 2 percent of international

HIGH TECHNOLOGY FIBRES FOR TECHNICAL TEXTILES 1 INTRODUCTION Human life is surrounded by hundreds of textile fibres either in the form of clothes‚ interior textiles or in the form of high performance technical textiles made of conventional or high technology fibres for various applications. A textile fibre is usually defined as a flexible‚ macroscopically homogenous cylindrical body mainly with circular cross- section having a high ratio of length to diameter (typically 100-3000: 1). Textile

Illusion Versus Reality In Shakespeare’s famous tragedy Hamlet there is a dominant and overwhelming theme that is amplified throughout the entire play. Things are not always what they seem. Many of Shakespeare’s most complex characters hide behind multiple masks of lies and deceit. The American Heritage Student Dictionary defines illusion as “an unreal or misleading appearance or image” and reality as “the state of things as they actually exist”. The focus of this essay is the struggle between
