...Modeling and Designing of a New Indoor Free Space Visible Light Communication System∗ Z. Wu, J. Chau, and T.D.C. Little Department of Electrical and Computer Engineering Boston University, Boston, Massachusetts tdcl@bu.edu August 1, 2011 MCL Technical Report No. 08-01-2011 Abstract–Recent developments in solid-state light-emitting diode (LED) materials and devices is driving a resurgence into the use of free-space optics (FSO) for wireless broadband communication. This technology uses the visible spectrum provided by “white” LEDs that are becoming ubiquitous in lighting and has some desirable properties competitive with existing radio frequency (RF) communications. By leveraging the low-cost nature of LEDs and lighting units there are many opportunities to exploit this medium for widespread optical communication deployment. The optical medium, however, has particular characteristics, including directionality and susceptibility to noise sources in the visible spectrum that must be managed. In this paper we present a new indoor FSO system, also known as a visible light communication (VLC) system that addresses achieving satisfactory data rates through diffuse link while supporting mobility under line of sight (LOS) constraints. The system model is presented with theoretical performance analysis indicating a promising rate for indoor scenarios. The new VLC prototype that can deliver in excess of 1 Mbps while providing both illumination and communication at several meters is also...

...MINI PROJECT ON AUTOMATIC STREET light An introduction: Needs no manual operation for switching ON and OFF. When there is need of light. It detects itself weather there is need for light or not. When darkness rises to a certain value then automatically street light is switched ON and when there is other source of light i.e. day time, the street light gets OFF. The sensitiveness of the street light can also be adjusted. In our project we have used three L.E.D for indication of bulb but for high power switching one can connect Relay (electromagnetic switch) at the output of pin 3 of I.C 555. Then it will be possible to turn ON/OFF any electrical appliances connected all the way through relay. Principle : This circuit uses a popular timer I.C 555. I.C 555 is connected as comparator with pin-6 connected with positive rail, the output goes high(1) when the trigger pin 2 is at lower then 1/3rd level of the supply voltage. Conversely the output goes low (0) when it is above 1/3rd level. So small change in the voltage of pin-2 is enough to change the level of output (pin-3) from 1 to 0 and 0 to 1. The output has only two states high and low and can not remain in any intermediate stage. It is powered by a 6V battery for portable use. The circuit is economic in power consumption. Pin 4, 6 and 8 is connected to the positive supply and pin 1 is grounded. To detect the present of an object we have used LDR and a source of light. LDR is a special type of resistance...

...I sit on the old courthouse steps in the town square of Denton in the great state of Texas. The square is filled with people from all walks of life. Nestled between two universities and surrounded by residential neighborhoods, this place is constantly alive with people coming and going. I find myself humming along to the sounds of music coming from a group of young college kids who have set up their instruments and are performing on the courthouse lawn for all to enjoy. A gentle breeze picks up and with it is carried a glorious scent of bbq wafting over from one of the local restaurants. This place plays host to many festivals throughout the year. From where I am seated I can see the strings of white LED lights strung throughout the trees on the courthouse lawn. In the evening these lights are turned on creating a lovely ambiance. This is the type of place where the waitress at the diner knows your name and order as soon as you walk in the door. This is that small town America that for so many years I looked for and finally have found. I sit on the steps of the old courthouse here in Denton, Texas. The courthouse square is packed with all sorts of people. Many have walked here from a few blocks away due to the limited parking options. Just a few feet from me, an amateur band of college kids have set up and are using the courthouse lawn as an open air practice studio. Walking about the square, darting in and out of the waves of people, I duck into a diner. The waitress...

...Pioneer Petroleum Case Analysis Pioneer Petroleum Cases Analysis The Problem: Pioneer Petroleum Corporation (PPC) has two major problems that are interfering with the goal of the firm to maximize shareholder wealth. The first is that PPC has been calculating their weighted average cost of capital incorrectly, by incorrectly calculating their after tax cost of debt and their cost of equity. This miscalculation has subjected PPC to more risk and has hurt the company’s ability to make appropriate investment decisions. This has also led PPC to accepting investment decisions that should not have been included within their acceptable range. Second, PPC has been using a single company-wide rate for their multi-divisional company. In either instance the company is not maximizing wealth. Statement of Facts and Assumptions: PPC has been calculating their after tax cost of debt using the coupon rate of 12% instead of the actual interest rate which is 8%. Taking the 8% interest rate into account, PPC’s actual cost of capital would be calculated as: [.08(1-.34)]= 5.28%. PPC has simply been using 10% (their equity growth rate) as their cost, but must instead either use the CAPM model to calculate their cost of equity, or the Dividend-growth model. If they use the CAPM model, which is the most accurate, their cost of equity will be: .078+.8(.1625-.078)=14.56%. Or they can use the Dividend-growth model and their cost of equity would be: (2.7/63)+.1=14.29%. Both are...

Full form of LED is light emitting diode. The concept of LED is pretty simple. Like every other diodes, LED is made of semiconductor filled with impurities from Group IIIA and GROUP VA elements, creating a p-n junction. As electricity flows from the p part to the n part, holes from the p part meet the electrons from the n part. When the holes and electrons meet, they radiate energy. In LED, this energy is used as light. Electroluminescence, the basic concept of LED was discovered in 1907 by H J Round. But until 1968, LEDs were very costly and inefficient for commercial and personal use. The Monsanto Company was the first industry to mass produce LED lights for indicators in 1968. After that, there had been quite some developments in LED technology resulting in the efficiency to rise exponentially with a doubling... READ FULL DOCUMENT Introduction p. 3 II.

...strategies has financial costs and benefits. These are discussed below. 1) Ten per cent increase through efficiency The efficiency improvement strategy carries no costs and should yield 10 per cent on the bottom line, or about an additional $12,100 profit. The calculations are: $550,000 annual revenue x 2% margin = $11,000 net profits $11,000 net profit x 10% efficiency improvement = $1,100 $11,000 + 1,100 = $12,100 increase in net profits 2) Add adventure diving The adventure diving resort strategy will require about $15,000 to get started. It should yield about $95,680 additional revenue. The calculations are: 8 divers per trip x $115 for each diver = $920 revenue per trip $920 each trip x 2 dives per week - $1,840 revenue per week $1,840 revenue per week x 52 weeks = $95,680 annual adventure diving revenue 3) Focus on family diving The family diving resort strategy will cost $60,000 to $160,000 (in renovations and improvements) and should yield at least an additional $157,000 over current revenues, assuming no increases in prices. If Coral Divers raises its prices to equal other family resorts, the revenues should be even higher. Two methods of calculation are shown below. Method 1: Occupancy during high season is 90 per cent, so: 90% (“x”) = 0.90x [where “x” equals total seasonal revenue] And occupancy during low season is 50 per cent, so: 50% (“x”) = 0.50x [where “x” equals total seasonal revenue] ...

...whether a floor price and taxing on alcohol would benefit Thailand’s population and also whether the UK should trial similar ideas. A Simple Model for Demand To be able to work out the effect that the increase in demand will have on the annual consumption I would have to interpret the data given in the report. As we are told, the price per litre of alcohol is expected to increase by 60% to 2,500 Baht in 2013, I was therefore able to work out that in 2012 the average price of alcohol would have been 1,562.5 Baht per litre by doing the following calculation: 2500 / 160% = 1562.5 2500 / 160% = 1562.5 378 / 100 1.5 = 372.33 378 / 100 1.5 = 372.33 Moreover, as we were also told in the report the annual amount of alcohol consumed in 2012 was 378 million litres and that this is expected to decrease by 1.5% by 2013. I was able to calculate the predicted amount of litres of alcohol consumed by doing the simple calculation: An Equation for the Demand Curve The information that I have formulated above has allowed me to be able to calculate the gradient and more importantly the equation of the demand curve between Thailand’s annual consumption of...

...now trading at $37.41 and $78.69, which are both significant rises since five years ago. After finding the closing monthly stock prices for Wal-Mart, Microsoft and the S&P 500, as well as the monthly yield for a 30-year T-bond, we took their average for each to find the expected return. Respectively for Microsoft and Wal-Mart we found the expected returns were 1.54% and 0.88%. For Microsoft this is well above the benchmark of the S&P’s expected return, which was 1.30%, while for Wal-Mart it is well below the benchmark. We also found that Microsoft and Wal-Mart’s expected returns are higher than the average monthly yield of a 30-year T-bond, which is good because it shows they are outperforming a risk free asset. Following our calculation of expected return we went onto other risk and return measures like variance and covariance. The variances of Microsoft and Wal-Mart are 0.47% and...
