Fall 1996, we asked students to fill out a questionaire. Although we are stillworking with the raw data, several inferences can already be drawn.EECS 100 vs. a course in CTable 1 provides the raw data arranged as follows: Each of the eight rows corresponds to one ofthe eight conditions of the three variables:a. whether the student ever wrote a computer program prior to EECS 100 (Yes, No). b. whetherthe student was happy he/she took EECS 100 (Happy, Unhappy). c. whether the student inretrospect would have preferred C or EECS 100 (C, 100).The columns correspond to the grades they received in the course. Of the 208 students whoanswered the question, 179 (86%) were happy they took EECS 100, 29 (14%) were not. Of the208 students who answered the

Some co-op employers hire only for double blocks,wanting the student for six consecutive months.DFMA is a required course for fourth year students. Prerequisites are Geometric Dimensioningand Tolerances and Manufacturing Processes. A normal track student will have completed twowork blocks prior to taking this course. Due to a significant number of transfer students, andstudents who have experienced academic problems, the class usually has a few third year students,and several fifth year students.The course covers two major areas: Design for Assembly (DFA) and

lowpass averaging filter with 5 x 5 coefficients was applied to the Alane image in Figurel(a) to generate the image in Figure l(b). Note that the effect of lowpass filtering is asmoothing or blurring of the edges. In contrast, the highpass filter was used to generateFigure l(c). In this image the edges have been accentuated, which is why highpass filtersare often known as “edge detectors.” Visualizing the result of convolving a filter maskwith the data helps provide the intuition necessary for understanding how a particularfilter can change an input signal.3.2.

The following considerations must all be satisfied: (a) The total laminate can not have less than four, and not more than six, plies (b) The resulting tensile stress concentration factor on the edge of the hole must be between 2.6 and 3.0. (c) The maximum laminate tensile strain on the hole boundary must be between 6800 and 7300 microstrain

The variables, p2 and p8, list the coefficients of the 2nd and8th order polynomial, respectively, starting with the highest power first. According to the Figure 1-b, the 2nd order polynomial is a gentle curve that follows the datatrend. However, the 8th order polynomial varies more between the data points. This suggest thatthe 8th order polynomial is not a good function for interpolation between

gatheringinformation from a variety of engineering texts and interviewing both engineering faculty andconstruction firms, the students selected four controllable variables and three interactions, eachwith two levels, (Table 1), which resulted in a total of seven degrees of freedom. Hence an L8orthogonal array was selected for the inner array. The four controllable factors were, regular tapwater, (A), Portland cement (type I), (B), pea-gravel, (C), and sand, (D). The three interactionswere between: water and cement, (AxB); water and coarse aggregate, (AxC); and cement andcoarse aggregate, (BxC). The two uncontrollable (noise) factors were humidity, factor X, andtemperature, factor Y. Studying the interaction between these noise factors required threedegrees of

There was no curve: an A is earned with an average from 90to 100, a B from 80 to 89, a C from 70 to 79, a D from 60 to 69 and an F for below 59. Infact, students in EElOl preferred not to have a curve, as they were afraid that a few giftedstudents or science majors would spoil the grade for the rest. Three exams were given during the semester, with an optional final exam. If a studentdid badly in an exam, he/she could take it again during the finals period and the higher scorewould be used in computing the grade. This approach follows this instructor’s view thata
