display involving analog to digital conversion and laser bit communication was constructed. The exhibit also demonstrates how more bits can be used to communicate a more accurate signal. For this task‚ an audio information source (CD player) produces a signal that is converted to digital information. This information will then be sent to a receiver using laser light switching on and off to communicate zero’s and one’s. The receiver will pick up the laser light and convert the digital information back

Learn how to create laser graffiti This week‚ I met with the gentlemen of Graffiti Research Lab Vienna‚ aka‚ GRLv‚ and they were kind enough to break it on down and show me how to set up a laptop‚ camera‚ projector‚ and laser to be a nondestructive and awesome graffiti tool. The following is copied directly and without edits from the README file as found in the Laser Marker zipfile that you can find in the sidebar at http://graffitiresearchlab.at.

Name: Nguyễn Dạ Thảo Linh. ID: BABAWE11068. Individual Assignment. Session 10 - Questions for the case "Peerless Laser Processors". Question 1: Describe the business performance of Peerless before the purchase of the state-of-the –art punch presses in 1991 and after that? (2.5 points). Answer: In 1981‚ the company faced a do or die decision that forced them to use new technology. If the lasers failed‚ the company would have had nothing to fall back upon. There was no good economic justification

way to identify the brand of lipstick someone was wearing at a crime scene without removing the evidence from its bag‚ avoiding contaminating the evidence (2013). The technique by the name of Raman Spectroscopy was used (2013). This method detects laser light allowing for investigators to analyze lipstick marks left at the crime scene (2013). “Analyzing lipstick traces can be used to establish physical contact between two individuals‚ such as a victim and a suspect” (2013). This advancement is significant

different experience. The presentation held in the planetarium and the environment of this room was dark except domed ceiling and exit sign. The instructor was really informing people and kids very friendly. Instructor was describing stars with the red laser light point to understand a better view of the stars and galaxies. Kids liked that presentation because instructor was very friendly with them and he was showing stars with comparing shapes of dragon‚ dog and hunter. There was also a telescoping viewing

The second type of measurement that coincides with distance is speed. The most common devices that are used to receive speed measurements are radar guns. Georgia State University’s website‚ “Police Radar” focusses on the process of typical radar guns. Typical guns expel microwave waves off to the atmosphere while the gun is directed to hit towards a target From there‚ an object moving by who hits it sends the waves back with its modified frequency caused by the Doppler Effect (Georgia State University

Creative writing! The End Before My Eyes! ‘Another typical day‚’ I said to myself when I woke up this morning; but I could never have been so wrong in my entire life! It was a Tuesday morning and the moon was still out. I didn’t think anything of it at the time. I bathed and got ready to get out my house since my bus was due in 10mins. As soon as I got out the moon became the colour of pure red blood. It intrigued me. So I got on the yellow knocked up bus and got out my little ‘Blue Note’

Light that is visible to the human eye is a small portion of the electromagnetic spectrum which can vary in colour based on the wavelength of what is being seen at any particular time. This visible light has a primary function of causing electrons to become more active with higher energy rates. The colour that is seen revolves around the size of this portion which is noted as the wavelength. White light is a culmination of all colours which is the cause of it being the brightest. Furthermore‚ when
