Attracting talented high school graduates and impartingthe best possible civil and construction engineering education is critical to the future of the U.S.construction industry.In the early 1980’s the construction industry faced increased national and internationalcompetition, stringent governmental regulations, and an environmentally conscious populace.The industry also encountered issues such as organized labor, challenges of new technologiesand new materials, and construction of complex projects. These forces emphasized the value ofstrong engineering and management skills required for

Inaddition, a preliminary study of the problem was conducted. A typical AS/RS system consists ofthe following components: storage structure, storage/retrieval (S/R) machine, storage modules(e.g., pallets for unit loads), and pickup-and-deposit stations. The primary issue was to whatdegree the AS/RS model should mimic the real system. After careful consideration, the

First, Chuck Roth will fill you in on the Personalized System of Instruction, or PSI, aself-paced system of instruction best known as the Keller Plan. Fred S. Keller developed thismethod in the 1960s in Brazil, and he and Gil Sherman refined it later at Arizona StateUniversity. Billy Koen at the University of Texas first applied it to engineering education in1969, and his success encouraged Larry Hoberock, Chuck Roth and Gerry Wagner to use themethod in their classes. Later, the Alfred P. Sloan Foundation provided a sizable grant toexpand this activity, and ultimately, 19 PSI

observations we have already made. The fundamentalnotation of Bayesian statistics can be stated as that of conditional probability, P ( H \ E ) ,which is the probability of hypothesis H given that we have observed evidence E 11. It isnecessary to take into account the prior probability of H and the extent to which E providesevidence of H. To do this, we must define a universe that contains an exhaustive, mutuallyexclusive set of H i ’s among which we are trying to discriminate. Then let P ( H i \ E ) = The probability that hypothesis H i is true given evidence E P( E \ Hi ) = The probability that we will observe evidence E given that hypothesis i is true P( Hi ) = A priori probability that hypothesis i is true in the absence of any specific evidencek

The MATLAB script file for the audio portion is shown in Figure 1. Initially, thesampling rate is 36000 samples/s. The data is plotted and the sound played. Next, the sinusoidis sampled at 18000 samples/s. The two sampled signals are plotted on top of each other to seethat no aliasing has occurred. The signal is played to see if any audible difference can be heard.Finally, the sinusoid is sampled at 3000 samples/s, and plotted in comparison to the signalsampled at 36000 samples/s. The 2400 Hz tone has been aliased to 600 Hz. The signal isplayed, and the

There are also increasing numbersof non-traditional learners coming back to school or going to school for the first time in order toupgrade their skills or to obtain a degree (or another degree). For example, the number of highschool graduates is expected to increase 30% from 1992 to 2008. 5 It is further anticipated thatbecause of the economic factors associated with a college degree, high school graduates rate ofattending will likely increase.
