Inorder to properly analyze the wind speed, we determined the portion of the month windspeeds were above 3.2 meters per second (the lower speeds do not contribute any output)and the average of those speeds (see Table 2), we determined an average speed of 4.5m/soccurring 35% of the time (10.5 days/month).

) codes demonstrate high performance capabilities, arbitrarily close to the Shannon limit,and are becoming feasible with today’s processing technology [10]. LDPC codes are founded onbasic linear-algebra principles. In this paper math is performed in the binary subspace of real-numbers, and hence addition and multiplication are performed in base 2, e.g. addition becomesthe XOR operation, and multiplication becomes the AND operation. LDPC codes utilize a sparsebinary parity-check matrix, H, with dimensions M×N. Matrix H can be either regular, meaningthat there are a specific number of 1’s per row and column, or irregular, in which there may ormay not be a constraint on the number of 1’s. In this project we will deal only with an irregularparity

While the published formulaapplies to a material removal process only, due to the nature of the process it can be extrapolatedthat the same process variables (I, and Tm) apply for carbon nanotube manufacturing. Theempirical material removal rate formula is to be augmented as the results dictate. Based on thecurrent prices of carbon, and the cost of electrical energy as found from students’ electrical bills,an economical analysis is to be

’s (Lorenz 1963; Baker and Gollub 1996; Flake 2001). The dictionary meaning of the word “chaos” is complete disorder or confusion. Chaosin science and engineering refers to an apparent lack of order in a system thatnevertheless obeys certain laws and rules. This understanding of chaos is the same as thatof dynamical instability. Deterministic system can produce results which are chaotic andappear to be random. But these are not technically random because the events can bemodeled by a nonlinear procedure/formula. The pseudo-random number generator in acomputer is an example of such a system. A system which is stable, linear or non-chaoticunder certain conditions may degenerate into randomness or unpredictability (may bepartial) under other

instructions had to be doable andunambiguous. As the students quickly learned, even when the solution to a problem is wellunderstood, it is sometimes difficult to express the solution in elementary steps.The class then built on the idea of the kind of steps needed in an algorithm by writinginstructions for an imaginary S robot. The S robot was defined to be able to pick up one playingcard from a deck and hold it in its hand. It could make some determination about the card such asits suit or value and it could either put the card back on the top of the deck or discard it to thefloor. The students were again placed in groups, given some playing cards, and assignedproblems to solve of the nature: count the number of cards in the deck. New instructions

The collaborative environment of theactivities arranged by these societies may be a contributing factor in the change.Historically, about one-third of all bachelor’s degrees have been awarded in science and engineering.Even though women are 56% of the college population, women earned only 19.5% of engineeringbachelor's degrees in 200511.
