Flip-flops areNOT fundamental circuit components, as is taught in introductory courses. Flip-flops aredesigned from more elementary components using asynchronous techniques. The purpose forthis paper is to remind digital circuit designers that to understand fully the principles they use intheir designs, they must apply knowledge of asynchronous sequential circuit design.BasicsSequential circuits, or finite state machines, are designed around the templates shown on the nextpage.

Some of the sinkhole A zones in the city were not made AE zones because standardmethods gave 100-yr flood zones much lower than those observed in large events. Figure 1shows three sinkhole flood zones, of which two are approximate A zones. Accurate determination of flood zones requires several things: 1) accurate topographicsurvey data, 2) application of appropriate hydrologic and hydraulic models, 3) good calibrationdata, and 4) familiarity with the watershed. Each of these four requirements for good flood mapsis a link in a chain. Failure to provide any one of the links can significantly reduce the accuracyof the map. A

Although the typical undergraduate curriculum is crowded enough as it is, and studentshave the ability to learn how to deal with these difficulties through elective courses and graduatestudy, it is important that the students come away knowing that these subtleties exist and thatthere are techniques out there for dealing with them. Much of the advancement taking place incontrols education seeks to address these deficiencies through laboratory work and project-basedlearning.1 2 A specific area of control system design and analysis that even many advanced graduatestudents are unaware of is that of discrete event system (DES) control. Discrete event control isoften confused with digital control. Whereas digital control systems

An unnecessarily large Pc couldinterfere with the healthy academic atmosphere in the class without necessarily leading tosignificant increase in control over cheating, as will be evident from the following analysis.We assume that the probability of getting caught in a given activity (e.g. a quiz or homework) isindependent of the probability of getting caught in any other activity. Therefore, the probabilityof getting caught at least once in n incidents is given by:This is plotted in figure 1 for various values of Pc for a range of n up to 40. It is

Beginning with the Class of 1980 only those students interested in furthering theirstudies in engineering took both Thermodynamics and Fluid Mechanics. All other cadets took anew course, Thermofluid Dynamics (ME304), that covered selected topics in thermodynamicsand fluid mechanics to provide “essential engineering knowledge necessary to understand thecomplex mechanical world of the U.S. Army”.1 Curriculum revision in the late 1980s requiredall non-engineering majors to take a five-course engineering sequence comprised of five coursesfrom one of the ABET-accredited engineering

(hereinafter called the “RC”), is a tabletop steam-electric power plant that looks andbehaves similarly to a real steam turbine power plant (see Figure 1). It also has the advantage ofrelatively low-cost. About the size of an office desk, the plant contains three of the four majorcomponents of a modern, full-scale, fossil fuel fired electric generating station: boiler, turbine,and condenser. Using only propane and water, the plant will actually generate electricity. Notethat the RC does not operate in a true cycle (there is no pump); it is a once-through unit (seeFigure 2). Nonetheless, many of the key issues regarding steam power generation are illustratedby the device.The RC is outfitted with sensors to measure key properties. The data is displayed

Two recent Gallup polls had asked thesame question 1, 2 , and nearly 70 percent of respondents, all adults, also said computers.(The next most common response, at 4%, was "electronics.")
