and the B-50 Connector Block tocollect data. This simple arrangement is structured to make data acquisition look “as easy as”connecting wires to a computer. Later labs use the NB-MIO-16 I/O Board with the appropriateSCXI components needed for each particular transducer. By then, the students begin toappreciate that data acquisition is much more than simply connecting wires to a computer.Lab activities for the Experimental Methods course include an introduction to first and secondorder systems, calibration, error propagation, uncertainty analysis, torsional vibration, thermaltime response, frequency response, and independent projects. Before shifting to a virtualinstrumentation basis for this course, the lab activities tended to center on data

four columns, the DTMFencoding supports 16 distinct keys. A touch-tone keypad has four rows, three columns, andtwelve buttons, the numbers 0 through 9, plus “*” and “#”. However, the frequency for a fourthcolumn is available for encoding in the system. To use the additional four keys, defined as A, B,C, and D by the telephone system standard, all that would be needed are four additional buttonsand contacts connecting the four rows to the additional column. Figure 3. DTMF dial Standard touch-tone telephone keypads have two contacts per button. For example,when button 1 is pushed, one contact turns on the 697-Hz oscillator, and the other one turns onthe 1209-Hz oscillator. The buttons on the top row of

During the first 80C552 external bus cycle, the IS and IRD control lines of the IDMA port are asserted and the MS byte of the data is read and the LS byte is written to latch B. For the second bus cycle, the output enable of latch B is asserted and the LS byte of the data is read. Glue logic for the interface is programmed into a GAL16V8 PLD to reduce chip count.V.

. Flexural Behavior of Reinforced Concrete Beams OVERVIEW This module illustrates the traditional concept of under- versus over-reinforced concrete beams, and the newer concept of relating the strength reduction factor to the anticipated failure mode—the so-called unified design procedure of Appendix B to the ACI concrete code11. In a nutshell, the idea is that a reinforced concrete beam fails in a brittle manner if the compressive strain in the concrete reaches its crushing limit before the tensile strain in the reinforcing steel reaches its yield limit. The design characteristic that controls this, given a set of material properties, is the ratio of steel area to concrete area. The distinction

We seek to provide a concrete startingpoint in order to facilitate such modifications, not in order to close discussions of professionalwriting. Based on our experience, we advocate that every engineering department develop oradopt a similar set of writing and report standards based on explicit examples of the reportsexpected to be generated by their students, and we further propose the set of reports describedherein as one representative set of examples.REFERENCES Carosso, R.
