For over 10 years i have been awed by the magnificent sport of roller skating. It wasn’t until i was about 5 years old when i actually attempted to try the epic sport myself. I stood in the big pale yellow house that was owned by my mother and my over-cranky step-father. It was a really ancient house even though it wasn’t built to long ago. The strawberry-milk colored shutters were creaky when opened, the paint on the outer part of the mansion like structure was peeling rapidly by the day. The

Light emitting diodes, also known as LEDs have really changed the way people think about lighting. An ordinary incandescent light bulb uses up 90% of energy it consumes as heat. Also, they last about 900 hours. The LED lasts about 25,000 hours, which is equivalent to 22 years. This is a major difference. Origins of the Technology: In 1962, Nick Holonyak Jr. invented the first light emitting diode, also known as the LED light bulb. He was a general Electric researcher. Some of the first work done

Tennessee Williams was once quoted as saying 'Symbols are nothing but the natural speech of drama...the purest language of plays'. This quote is especially true for his work A Streetcar Named Desire. As in all Williams' plays light plays a crucial role in the struggle between the main characters. Blanche and Mitch have a discussion about their names and ages in the bedroom while the others are playing poker. After a while, Blanche claims, “I can't stand a naked light bulb, any more than I can a rude

Tennessee Williams uses various motifs, background music and light to explore the theme of reality vs fantasy, eventually showing how Blanche loses hold of reality and slips into insanity. Throughout the play, Blanche struggles to tell between fantasy and reality, because of her strong desire to remain youthful, protect her status as a Southern Belle and the traumatic memory of Allan's death. The motif of light represents both the reality of Blanche's past and present self, thus avoiding light

Introduction In this two part lab we are to build a spectroscope from parts included with our lab kit to visualize and analyze the spectra of several light sources. In the second part of the lab we are to build a pinhole viewer. We are to then take the pinhole viewer and measure the diameter of the sun and moon. After completing both parts of the lab, there are several questions that need addressing. This paper examines and answers those questions. Spectroscope To understand this week’s experiment

The system bandwidth is 8 MHz located from 2 MHz to 10 MHz. The point to point system (with one LED lamp on) can still work well with the visible light path Fig. 9. PLC modulator. Fig. 10. Demodulator in the receiver. up to 8 meters with the interference from the normal indoor lighting devices and provide a date rate of around 48 Mbps within 8MHz bandwidth. For the two LED lamps, LED A is connected directly to the PLC modulator and LED B is connected to the modulator via a section

Dear Property Managers of Domain College Park, The purpose of this letter is to propose a solution to the frequent problems at the Doman College Park apartment complexes. The solution involves implementing the Energy Efficient Lighting Program (EELP) in order to reduce the energy consumption problems in the building. Proposal Synopsis In this letter, I present a proposal to implement the Energy Efficient Lighting Program for the Domain College Park apartment complexes. The problem is that the

Climate change, also know as global warming, is a huge, global issue in our world today. Eventually, our lives “may be threatened by rising sea levels, disrupted food production, extreme weather, and emergent diseases” (TGES). Since 1750 and the early 19th century, “the planet's average surface temperature has risen about 2.0 degrees Fahrenheit (1.1 degrees Celsius) since the late 19th century” (NASA GCC). But why are people worried about the future of climate change? Well, global warming is dangerous

In the year 2009, there were 39.6 million adults who were 65 years or older. Baby Boomers made up about 12.9% of the population or roughly 1 in every 8 humans. By the year 2030, this number is expected to almost double making 72.9 million adults who are aged 65 years or older making up for an astounding 19% of the world's population. All in all, 5% of the world’s population are in nursing homes. Lighting should be a primary concern to those living in, working in, and designing Nursing Homes. Light
