“Mirage: An optical effect that is sometimes seen at sea‚ in the desert‚ or over a hot pavement‚ that may have the appearance of a pool of water or a mirror in which distant object are seen inverted‚ and that is caused by the bending or reflection of rays of light by a layer of heated air of varying density.”(Merriarn-Webster’s Medical Dictionary) Imagine yourself walking alone in the desert‚ you haven’t drink any water for a long time‚ you were tired‚ thirsty and exhausted. Suddenly‚ there was

The article by the various authors listed above concentrated on the various techniques that are used to locate and then to excavate these sites. They list and discuss the various techniques that they use. These vary from side-scanning to locate the sites to high resolution video to see how the site appears and the various locations

Rock art documentation by using multispectral is becoming popular in the cultural heritage domain. Multispectral is a camera with multi-lenses and sensors‚ which can take pictures of an object by multi-wavelength at the same scene. Usually‚ the advantage of using multispectral is it can detect an invisible object because it equipped with Near Infra-red (NIR) band‚ which is useful in reflecting the invisible spectrum. However‚ in the application of rock art documentation‚ multispectral is only focused

Nt1310 Unit 8 Assignment Splicing and Connection Performance In this paper you will find 3 factors that could affect splicing performance‚ 3 intrinsic factors‚ and 3 extrinsic factors. 3 Factors that could affect splicing performance could be attenuation‚ modal dispersion‚ and chromatic dispersion. Attenuation can cause splice performance issues because of dirty fiber end faces‚ excessive gaps between fibers or improperly installed connector offsets of fiber cores when mated. Modal Dispersion also

Lori Stenbeck Bio K121 June 7‚ 2012 The Microscope Introduction: The purpose of a microscope is to see either enlarge images of small objects and or make seen what is invisible to the naked eye. We have two types of microscopes available in the lab. The dissecting microscope is designed to study objects in three dimensions at low magnification. The compound microscope is used for examining small or thinly sliced sections of objects under magnification that is higher than the dissecting microscope

Originally‚ a device known as the ’photophone’ was used to transmit sound. This replaced Thomas .A. Edison’s ’phonograph. Since the development of optical fibres ’photo phones’ and ’phonographs’ are no longer used or needed. Optical fibres have many advantages; they enable the sound messages to carry for 50km without any need for a repeater unlike other optical communication systems‚ which need repeaters at 1km intervals. Optical fibres have replaced other methods of communication for many reasons
