competitionitself to gather names and information from the students.The first information form is the “Pizza Ticket”. The schedule for the competition is postersession, distance announcement, lunch, car race, and awards ceremony. The high schoolstudents fill out the pizza ticket and turn it in as they get their food. The pizza ticket serves twopurposes: (1) we get the demographic information that we are interested in and (2) we can keepthe University students from eating the lunch before the high school students do. The pizzaticket is shown in Figure 1. The pizza ticket from the 2003 race did not prompt the students formajor, and the majority of the students simply answered “college”. Results from the 2004 ticketswere much more specific

is the literature review 1. This means that students need tobe familiar with the current related research in their selected areas, and must be able to reflecttheir knowledge of this work in their research papers. Unfortunately, many graduate studentslack sufficient experience in compiling information from a variety of technical sources andpresenting these results. There are a variety of useful handbooks that describe the mechanics ofwriting, such as the texts by Davis 2 and Day 3. However, instructor guidance is necessary to aidstudents in both the selection of an appropriate research topic and the selection of relatedresearch articles 4. This paper describes a specific procedure for implementing this process. Proceedings

of students is not economical or readily available.To satisfy the dual requirements of diversity and cost efficiency, two students, one electrical andone mechanical, were offered special topic engineering credit to design and build this fluid flowequipment under the supervision of faculty mentors.MAF TheoryAutomotive mass airflow sensors (MAF) are used to calculate the amount of air entering theengine intake of an electronic fuel injection system. There are two types of automotive MAFs,digital and variable voltage (analog). Both use a “hot-wire” principal.The hot-wire principal uses a resistor (usually a coil of wire) that is heated by a constant voltage.The coil of wire is placed in an airflow-sampling channel. See Figure 1. The entering

students still have rather limited practicalunderstanding of how to apply these basic principles to laboratory measurements thatinvolve real time-varying signals. Courses involving the detailed statistical treatment oftime-dependent random signals are not part of the MNE curriculum since they generallyhave prerequisite requirements beyond the reach of our typical undergraduate students.In addition, while available course textbooks (e.g., [1], [2]) usually provide a gooddiscussion of the statistical treatment of random errors, they do not generally address thepractical issue of how to actually perform independent sampling of time-series data.The Sampling ProblemIt is typically assumed that the samples of measured variables used in statistical
