6) The light distributors in each room include a lighting level adjusting unit to allow users to select their preferred lighting level. Each room adjusting unit communication to the rooftop control unit through PLC (Power Line Communication) [24] to let rooftop control unit determine how much sunlight should be switched into the room. If all sunlight is switched in and still not enough for the user selected lighting level, LEDs will be turned on to supplement. (7) Long system life and low maintenance

Key Advantages of the Keyence VHX-6000: • Advanced Focusing • Accurate Dimensional Measurements • Contamination Analysis in line with ISO 16232 Standards • 3D Display and Measurement The Keyence VHX-6000 microscope has been found to have many of the key aspects needed to analyse and quantify sub-surface defects on samples taken from the GKN traveller specimen. It has many advanced capabilities that lead it to producing sample images of exceptional quality. A key requirement in this task was

Fibre Optics Materials http://www.madehow.com/Volume-1/Optical-Fiber.html Invented by Alexander Brambell, a fibre optic cable is a single, hairline piece of cable mainly made from silicone dioxide and other tiny amounts of chemicals are usually added. Liquid silicon tetrachloride in a gaseous stream of oxygen is the most important and commonly used source of silicon in the vapour deposition method which is very commonly used. Other chemicals are sometimes used to produce outer shells and

retina. When light enters the eye and hits the photoreceptors (rods and cones) located in the retina, the retinal ganglion cells are activated. The retinal ganglion cells are organized in the retina and then are sent to the optic nerve, which is located at the back of the eye. The optic nerve transports the signals from the retinal ganglion cells to the lateral geniculate nucleus (also abbreviated as the LGN). The thalamus is the structure that houses the lateral geniculate nucleus. The primary function

responsible for responding to light, focusing and transmitting light through a lens. The human brain consists of 12 cranial nerves that are either motor, sensory or contains both functions. CN Olfactory: primary sensory nerve that allows smell CN Optic: vision; primary sensory nerve CN Oculomotor: CN Trochlear: enables eye to look downward or inward CN Trigeminal: facial sensation; chewing CN Abducens: moves eye laterally CN Facial: contributes to facial expression CN Vestibulocochlear: Hearing

Good morning students and teachers, today I will be talking to you about the technology and physics behind the Compact disc otherwise known as the CD Everybody knows that the CD is slowly fading out and being replaced by a digital world where files and streams are the main methods of music delivery. But the CD is not yet done. What is a CD? A CD is a thin circular disc comprised of metal and plastic, the CD is about 12cm in diameter and is usually made up of 3 layers, it is capable of storing up

Two painters in history are known for their abilities to depict scenes in such realistic manners that you would never know they are actually producing paintings. These painters are named Johannes Vermeer and Albert Bierstadt. Both men came from different times and ethnic backgrounds. Dutchman, Johannes Vermeer was born in the year 1632 and passed away in 1675. Over his lifetime Vermeer used a style of painting that causing modern day historians and art lovers to struggle to figure out how he painted

Olivia Silvestri Due: 10/19/15 Using a Compound Microscope Lab Report E Period Abstract The purpose of this lab is to learn about the parts and uses of a compound microscope. It is also to learn how to properly use and take care of the microscope. This lab showed me what materials and parts of the microscope I should use when examining an object. Introduction The microscope was invented by a father

abstract Photonic crystal is a composite dielectric with periodic modulation of refractive index that brings about unique photonic band-gap effect by which light could be totally reflected on the surface of such material regardless of any incident angle or mode. Such bandgap effect could be understood by investigating the optical performance of photonic crystals. In this paper, photonic bandgap calculations are performed for two dimensional photonic crystals using matlab. Plane wave expansion

Fantasy will always be more cherished than reality. Our imaginations give way to disappointment when it's time to buckle down and come back to the real world. However, for Nellie this is quite the opposite. In Anton Chekhov’s “The Looking Glass” character development, symbolism, and diction are used to communicate that reality upsets our expectations. Character Development is one of the most effective tools used to communicate the overall theme of The Looking Glass. Character Development is used
