consisted of five sequential lab activities in five consecutive weeks: the studentswere required to: 1) calibrate the level sensors and the pump; 2) model the coupled-tanks process with a transfer function; 3) obtain a closed-loop transfer function that satisfies the system performance requirements; 4) determine the controller’s transfer function Gc(s) and convert the transfer function into a difference equation that can be implemented as a digital controller on a computer; and 5) integrate the controller with the sensors, the pump, and the coupled-tanks apparatus to test and analyze the entire system’s performance.Each of these five activities is detailed in subsequent sub-sections.

Ligand-Receptor Interaction Figure 1 is a diagram of a simple ligand-receptor interaction where the rate constants kf (M-1 -1 s ) and kr (s-1) model the reaction associated with the ligand binding to the receptor and thereverse dissociation reaction respectively. The associated equilibrium reaction and the concomitant reaction rate equation are shown in(1) where R is the number of unoccupied receptors per cell, L is the free ligand concentration(M/dm3) and C is the number of bound receptor ligand complexes per cell

the United States. Nationwide this was accomplishedthrough the use of a method called triangulation. In this method a rather long base line ismeasured on one coast, say 25 miles, using a steel tape and taping bucks6. Using a transit toensure that the line is straight and leveling to determine the elevations of the ends of the tape, avery precise measurement is made of the base line (a very long and tedious task). See Figure-2on the left is a metric leveling rod, in the center a taping buck. The elevation of the end points ofthe tape are determined with dumpy level as shown in Figure-3.

Altogether, the students performed six laboratory exercises that weregraded. Four exercises were conventional, and two were inquiry-based.Tank FillingThe objective of the tank filling exercise is to develop in students a solid conceptual Page

overall human capital strategy. The remainderof the paper will focus on the STEP Program itself.A consequence of the end to the cold war was that the Department of Defense (DoD) found itselfwith an excess amount of infrastructure that was no longer required. The excess infrastructureincluded personnel no longer needed to support our post cold war efforts. This lead to congressauthorizing a number of Base Realignment and Closure (BRAC) rounds to be conducted into themid-1990’s that were intended to right size DoD both in physical plant infrastructure as well asin personnel resources. BRAC rounds were conducted every odd numbered year culminating inthe last, and most extensive, round occurring in 1995. This periodic BRAC process did reducethe size

Assuming positive answers to Step #2, the interested faculty develops a Progressive Research Project Master Plan. The Plan for a progressive research project must identify desired outcomes that can be achieved by successive groups of students in a series of 3- month research projects. This should be based on the results Step #1. Ideally this is done in conjunction with the students who completed the initial project. 4. Faculty, with students who have completed their project(s

It is a small field that is obscure from mainstreamScience and Engineering but shares the same principles and theories taught at any institution ofhigher learning. The function of this small group touches almost every action we do and everytransaction we make in our day to day existence. Two such examples of this that are easilyrelated to are

Students are required to upload some of their datafiles on the server to be used in post-lab analysis and homework assignments, linking labexperience to theoretical learning in the course.Finally, the students obtain hands-on experience with the software, which is widely used inindustry for control and data acquisition, thus they get a competitive edge in job hunting.10.
