design steps are overwhelmed by the necessity to know the instruction set andperform the book keeping required to keep track of all the control and timing signals. At WichitaState University we developed and began using the LIS-4 (4-bit limited instruction set)architecture 15 years ago for use in an Introduction to Computer Architecture course. In 1987this architecture was presented in a book on digital design [1]. This course is the third in asequence of 3 undergraduate digital design courses The last 4 years we have made use of acomputer aided logic design program called B2LOGIC which allows the students to build, test,and program the computer [2]. In the following sections we give an overview of the LIS-4 andthe design as required by the

engineering programs are currentlyundergoing a major change of life as the nuclear industry passes from a growing, building, powergeneration dominated phase into a steady power operation phase and a growing service/supportindustry. As nuclear engineering programs change to adjust to the changingemployment/practice environment, they wonder if their new programs will still meet ABET/EACengineering accreditation requirements. I have good news. ABET Engineering Criteria 2000was created to “assure that graduates of an accredited program are adequately prepared to enterand continue the practice of engineering.”1 This is exactly what we are trying to do with theongoing re-engineering of nuclear engineering departments and programs.ABET ENGINEERING CRITERIA

1 System OverviewThis implementation of LabVIEW illustrates the fundamental radar principles at acousticalfrequencies. An ultrasonic transducer is the heart of the system. It acts first as a transmitter andlater as a receiver. In the transmit mode, the ultrasonic transducer transmits 16 sonic pulses at49.4 kHz. These pulses propagate through space with the speed of sound toward the nearestobject and are reflected by it. The reflected pulses, or echoes, travel back toward the ultrasonictransducer which now switches to the receive mode. The time difference between the transmittedpulse and the echo can be converted into distance to the object by appropriate scaling.In this implementation, LabVIEW is used to

The gear wasmodeled using stick diagrams based on dimensions furnished by Lockheed Martin TacticalAircraft Systems (Puttman, 1995).Stick diagrams serve a purpose similar to that of the electrical schematic or circuit diagram, inthat they display only the essential skeleton of the mechanism which however embodies the keydimensions that determine the path of the motion. In the case of this analysis, the stick diagramwas taken a step further. Basic geometry was drawn to represent the

That is, the error messages must distinguish assembler errors from the Motorola M68000assembly language syntax errors, and the assembler must graphically highlight the line element (label, operator, oroperand) which caused the error

secondary effects, such as offset, drift, clock-jitter, etc., can become critical factors inintegrated applications. These effects must be understood and accounted for. For one example,the author presents an analysis of an ADC simulation that includes the jitter present in real ADCclock-circuitry.The analysis will feature a mathematical approach needed to determine an effective method forsimulating the jitter that is present in a real ADC clock. The Signal Processing Worksystem(SPW) will be used to implement a block diagram-based ADC simulation [1]. The basicapproach is to use one of the perfect ADC models within SPW and then add the clock-jittercomponent to the simulation. An analysis of an ADC model will be conducted to determine theeffect of

attrition,perhaps a great deal of it, is due to lack of academic preparedness or to lack of academicqualifications. In that view, the attrition is expected, even desirable, since the attritionis “washing out” those students who don’t “have what it takes.”This paper reports on a study of the 1050 students who entered Ohio State in Autumn1988 intending to major in engineering. We report four conclusions:1 - Of the 1050 students, 29 quarters later, 34.9% had completed a degree in engineering atOhio State, 30.8% had completed a degree in some other major at Ohio State, and 34.4%had left Ohio State without completing a degree.
