Introduction background Air traffic controller is a profession that are trained to expedite and maintain a safe and orderly flow in global air traffic control system. Means‚ the ATC are very important in conduct the air traffic so that there are no conflict occurs. A conflict situation occurs when two or more aircraft are too close to each other‚ violating the horizontal and vertical to separation distance of 5 nautical miles(NM) and 1000 feet in the current ATM standards. This profession need

“Let There Be Light” 18 November 2013 Finding the Medium between Happy and Healthy The authors Douglas J. Lisle PH.D. and Alan Goldhamer D.C. wrote the book‚ The Pleasure Trap: Mastering the Hidden force that undermines Health and Happiness‚ to reveal to people how to live healthy yet happy lives. The authors did an adequate job of revealing to their audience how sleep is an important aspect to our happiness. They are able to do this by connecting Thomas Edison’s invention of the light bulb to the

ev Sensotronic Brake Control (SBC™) works electronically‚ and thus faster and more precisely‚ than a conventional hydraulic braking system. As soon as you press the brake pedal and the sensors identify the driving situation in hand‚ the computer makes an exact calculation of the brake force necessary and distributes it between the wheels as required. This allows SBC™ to critically reduce stopping distances. SBC™ also helps to optimise safety functions such as ESP®‚ ASR‚ ABS and BAS. With Sensotronic

Light I | | INTRODUCTION | Light‚ form of energy visible to the human eye that is radiated by moving charged particles. Light from the Sun provides the energy needed for plant growth. Plants convert the energy in sunlight into storable chemical form through a process called photosynthesis. Petroleum‚ coal‚ and natural gas are the remains of plants that lived millions of years ago‚ and the energy these fuels release when they burn is the chemical energy converted from sunlight. When animals digest

Visible light (commonly referred to simply as light) is electromagnetic radiation that is visible to the human eye‚ and is responsible for the sense of sight. Visible light is usually defined as having a wavelength in the range of 400 nanometres (nm)‚ or 400×10−9 m‚ to 700 nanometres – between the infrared‚ with longer wavelengths and the ultraviolet‚ with shorter wavelengths. These numbers do not represent the absolute limits of human vision‚ but the approximate range within which most people can

gaining notoriety as an important means of expanding renewable energy resources. As such‚ it is vital that those in engineering fields understand the technologies associated with this area. My project will include the design and construction of a microcontroller-based solar panel tracking system. Solar tracking allows more energy to be produced because the solar array is able to remain aligned to the sun. This system builds upon topics learned in this course. A working system will ultimately be demonstrated

Light is everywhere in our world. We need it to see: it carries information from the world to our eyes and brains. Seeing colors and shapes is second nature to us‚ yet light is a perplexing phenomenon when we study it more closely. Here are some things to think about: Our brains and eyes act together to make extraordinary things happen in perception. Movies are sequences of still pictures. Magazine pictures are arrays of dots. Light acts like particles—little light bullets—that stream from the
