for Engineering EducationClass CommunicationLast year we begun using Blackboard, a website based software, as “communicationscentral” for the class. Its use has been very successful. As an example, the calendar forthe Fall 2003 course as posted on the website is given in Figure 1 (at the end of thepaper). All assignments and all instructions are also posted. The “communication”feature (email) allows efficient information exchange among all students, teams, clients,faculty advisors and instructors/facilitators. Student’s questions can be answered and, ifappropriate, the answers are communicated to the entire class via email and the web site.Grades are also entered into a secure location at the website to which individual studentshave

Therefore, NOx emissions result in lessefficient ozone production. The following have been found to contribute to air pollution:1. Sulfur dioxide is released when sulfur-containing fuels, such as coal and oil, are burned.Common sources of sulfur dioxide emissions are electric utilities and certain industrialprocesses, such as copper smelting. Sulfur dioxide at elevated concentrations can causerespiratory problems and also affects plant and crop production. It also can be a contributingcomponent of acid rain.2. Toxic

Science Foundation,however, among engineering professionals, 88% are White, 6% are Asian, and only 6%are minority [1]. To improve minority representation in engineering and engineeringtechnology programs, institutions of higher education have used a number of approaches,such as the increase of visibility of the engineering profession, mentoring students, andacademic support [2]. Strategies to recruit and retain students include hands-onapproaches [3, 4], field trips [5, 6], summer workshops [7], and software trainingprograms [8]. This paper describes a project that uses all these methods to attractunderrepresented students to science and engineering through a program that includespresentations at high schools, invited speakers, field trips, hands

with the DSK. Figure 1 shows a very simple Simulink modelthat samples an input signal present at the analog jack at 8 kHz, filters it, and sends it tothe analog output jack. The ADC and DAC blocks take care of configuring the hardwarecorrectly without further programming. To filter the signal, the “fdatool” (filter designand analysis tool) block allows the programmer to specify the filter characteristicsthrough a graphical user interface (GUI) and calculates the filter coefficients, as shown inFigure 2. Students are able to perform this simple filtering implementation at the end ofthe second week of classes. The facility of experimenting with different filter parametersand listening to the results keeps them excited about their project and

Educationmodeling of jointed structures [1]. Development of a novel finite element code requires ageneral approach to handle applied loads that may vary in magnitude and directionaccording to an arbitrary prescribed law. In the present work we propose a simple modelthat is able to capture load history effects through an incremental approach.A number of studies have been done in the past to investigate memory rules in contactand frictional problems, but mainly for the contact of two identical spheres. Analyticalanalysis was carried out by Cattaneo [2] , Mindlin and Deresiewicz [3] for several typesof loading scenarios. A general model for the same contact was proposed by Dobry et al[4] that is able to manage arbitrary variations in the applied loads. It has

The current levels (2001) are 28.10 and 12.26 tones/day respectively. Thetotal CO emissions by all modes, which are 123.99 tones/day in 2001 would increase to179.11 tones/day by the year 2025.Study indicate that cars, which have a share of 12% in passenger kms emit 38.6% of totalemissions, whereas buses, which have a 50.7% share in passenger kms are emitting 2.3% ofthe total emissions.

It does this by sensing the ambienttemperature, comparing it to the desired temperature, and producing a control action thatwill keep the ambient temperature at or near the desired temperature. This paperdescribes a project that involves designing, building, and demonstrating a regulatorycontrol system. The system will maintain the temperature of a process at a desired setpoint. Another goal is to incorporate a PC-based data acquisition system (DAQ) alongwith LabVIEW, a graphics-based programming language by National Instruments.LabVIEW has been used in many control systems applications [1-5].To demonstrate the functionality of the system

Again, here the demand is ofpractical nature.Due to the myriad of forces shaping EM programs, curriculum design and development is noeasy task in this field.

diametrically opposite format is what is often used in most Law Schools, where noevaluation is done on material comprehension and retention until the very end of term (finalexam).The concept of "chunking" and the capacity of short term memory were first discussed byMiller.1 The author sustained the idea that short-term memory could only hold 5-9 chunks ofinformation (seven plus or minus two), where a chunk is any meaningful unit. A chunk couldrefer to images, words, digits, or even people's faces. The concept of chunking and the limitedcapacity of short term memory became a fundamental element of all subsequent theories ofmemory.Applying chunking theory to student assessment builds on cognitive and educational psychology.Mislevy2 observed that

It is thus prudent to evaluate how these media arechanging students’ academic experience.In prior research [1, 2], we evaluated an instructional CD that is currently included withthe book Thermodynamics: An Engineering Approach [3]. In addition to presenting thestudents with text content, tables, and graphs, the CD also includes active learningtechniques such as interactive exercises, graphical modeling, physical world simulations,and exploration [2]. The aspect we were most interested in was how students interactedwith the CD. In a modified version that we provided to students, the CD automaticallyrecorded each student’s interactions in a log

This often invites adiscussion of Torricelli’s Law because some students are familiar with it from previoustextbooks.4 Torricelli’s law states that water issues from a hole in the bottom of a tankwith a velocity of v(t ) = C 2 ⋅ g ⋅ h(t ) [1]where h(t) is the water height above the hole at time t, g is the gravitational acceleration,and C is the Borda

It acted as the stress raiser with a known stressconcentration factor to accelerate the fatigue test and eliminate inconsistent clampingeffect at the end of the cantilever specimen. The testing frequency was capped at 10 Hzso that thermal degradation will not be a factor in the fatigue test. Figure 1 below shows aschematic of the experimental setup. A cantilever specimen was subjected to flexuralbending with the help of a minishaker. Operational frequency of 10 Hz was provided by afrequency generator to the minishaker and the amplitude of vibration was verified with anoscilloscope as
