In coastal environs, tidal salt and freshwater marshes and mangroveswamps (mangals) are typical 1.Although not easily defined, wetlands are often identified as transitional lands between uplandsand aquatic systems where the water table is usually at or

Seattle, WA, 28 June - 1 July 1998ABSTRACTThe primary goal of Rowan University's freshmen engineering course is to immerse students inmultidisciplinary projects that teach engineering principles using the theme of engineering meas-urements in both laboratory and real-world settings. Currently, many freshman programs focuseither on a design project or discipline specific experiments that may not be cohesively inte-grated. At Rowan, freshman engineers are introduced to industrial problems through a series of 4modules and a interrelated-interactive lectures on problem solving, safety and ethics. In this pa-per a the process engineering module using the vehicle of a cogeneration plant is presented.INTRODUCTIONThe Rowan engineering faculty are taking

The second course generally entails anexamination of non-ideal behavior – both for pure components and for mixtures, as well as phaseand chemical equilibria. These courses are often steeped in theory (particularly the secondcourse) and provide limited exposure to the specific applications in unit operations and inindustry where these non-ideal effects are significant. If one were to poll undergraduates inchemical engineering, I believe that many would feel that their undergraduate training in thiscritical area of chemical engineering did not provide them with: 1) sufficient

The act of closing the assessment loop or providing feedback to the program willprobably be the most difficult aspect for engineering programs as they implement assessmentplans to satisfy ABET Criteria 2000. Much of the assessment literature suggests that developingand agreeing upon goals is the most difficult aspect for faculty unaccustomed to discussingundergraduate education issues in great detail. However, the eleven goals in ABET Criteria2000, Criterion 3, provide a “default” position for faculty unable to or who choose not to definetheir own set of goals.1 There is also an extensive literature on outcomes assessment measuresused at a variety of schools.2-6 Closing the assessment

In fact, “current activities in the Baldrige Office suggestthat the development of additional award categories for the public sector are being seriouslyconsidered. An announcement of a new award category for education is anticipated in the nearfuture.”Whatever one may think of the TQM aficionados’ place in higher education, if their models canlead us to greater accountability, lower costs and higher quality, they will

A typical com-puter assignment in that era would require the student to carry out the followingtasks: 1.) Derive the model equations for the problem at hand, 2.) Find an appropri-ate numerical method to solve the model (mostly NLE’s or ODE’s), 3.) Write anddebug a FORTRAN program to solve the problem using the selected numerical algo-rithm, and 4.)

In literature they are also known as MA (moving average)and ARMA (autoregressive MA) filters, among others. An FIR filter is described by thefollowing difference equation:y(n) = b0x(n) + b1x(n-1) + b2x(n-2) +…….bN-1x(n-N+1) =N −1∑ b x(n − i).i =0 iOne important design method in FIR filters is the so-called windowing technique whichutilizes the Fourier series theory to express the impulse response in terms of

The current evolution is marked by major developments occurring on a monthly basis.One of the possible forms of the educational resources for the (near) future are stand-aloneprograms that are a primary learning resource for a course.

A number of investigators have studied the dielectric response using the waveguide orthe resonant cavity technique1-7. In this research, a microwave resonant cavity in the TE011 modeis used as a probe for dielectric studies as a function of temperature and frequency. The detailsof such a spectrometer have been given elsewhere4, but for the sake of continuity a block diagramof the complete system is given in Figure 1.
