Once the students have had a little experience computing area under the curve,they can begin to solve applications problems using this Riemann sum. Some illustrative examples:Problem: Find the work done hauling 40 feet of chain that is hanging from a window whose sill is 50 feetabove the street, if the chain weighs half a pound per foot.Solution: Since work is force times distance, and the distance is different for each point along the chain, wecan approximate the work done with a Riemann sum. For each slice, we can approximate its distance to thewindowsill by using the furthest point on the slice - thus using the Riemann rightsum. The

This third lab intro-duces students to the use of these analyzers as well as teaching them some important concepts in signalanalysis. To introduce some of the features of the B&K octave band analyzer, the students investigate andcompare the spectra of white and pink noise as measured in frequency bands. They observe that white noisehas the same energy at all frequencies, but has an increasing power spectrum on an octave band scale. Pinknoise maintains a constant octave band power spectrum, but its energy decreases with increasing

Experimental designs such as the Central Composite design@3~ (basedon the 2“ factorial design) or the Box-Behnken desigff-4) are used to collect data in a systematic way so that amathematical model to the response surface can be determined. The Box-Behnken design has the advantage overthe Central Composite Design in that fewer total experimental runs are needed and that the independent variablesor factors are varied between three equally spaced values. This design collects enough data so that a mathematicalmodel of the response surface can be determined. A simple response surface model is the polynomial: = .f bo + b]xl + bJz + b$j+ b

An “A” grade was earned by achieving a total point accumulation of >90% of the total possible on 6 activities (homework, class participation, midterm exam, and 3 projects). A “B” grade was awarded for an 80% total, or by achieving a 90% total on only 5 activities. By similar means a “C” grade contract was constructed. Since the students taking the course were a self-selected and highly motivated group, it was not surprising that the quality of the work we reviewed was uniformly outstanding. Eleven of the twelve students earned the “A” grade. At least two of the projects or portfolios will be available at the meeting presentation for review by interested attendees.

Doing this will reap several significant benefits (in the non-statistical sense). You will (a) gain an appreciation of how much work you have really done, (b) impress others (who will have no idea whether or not it has meaning), and (c) have a good excuse for sitting and staring at the wall. The real, and sometimes surprising, benefit of developing some type of visual representation [7] of your ideas is that you may be able to see causes, effects, and other relationships more
